[0095] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0096] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0097] The following description, with reference to the accompanying drawings, describes an outdoor air conditioning unit 10000 according to an embodiment of the present invention.

[0098] like Figures 1-16 As shown, the outdoor unit 10000 of the air conditioner according to an embodiment of the present utility model includes a housing 4000, a heat exchange device 1000, and a fixing component 500.

[0099] The casing 4000 has an installation space 411. The heat exchange device 1000 is installed in the installation space 411 and includes a plate heat exchanger 200, a throttling device assembly 100, and a valve island fastener 900. The throttling device assembly 100 includes a valve island 10, and the valve island fastener 900 detachably mounts the valve island 10 onto the plate heat exchanger 200. Thus, by detachably mounting the valve island 10 onto the plate heat exchanger 200 via the valve island fastener 900, the throttling device assembly 100 and the plate heat exchanger 200 are connected, integrating the plate heat exchanger 200 and the throttling device assembly 100. This improves the structural compactness between the plate heat exchanger 200 and the throttling device assembly 100, reduces the installation space 411 occupied by the heat exchange device 1000, and helps to reduce the size of the outdoor unit 10000.

[0100] In some related technologies, valves and heat exchangers are integrated into a single unit via a valve island 10, achieving miniaturization and centralization. However, the valve island 10 is connected to the valves via welding, and the valve island 10 is also connected to the heat exchanger via welding. The valve island 10 is typically made of aluminum alloy, while the connection part 5222 between the valve and the valve island 10 is typically made of stainless steel, as is the connection part 5222 between the heat exchanger and the valve island 10. The melting point of aluminum alloy is lower than that of stainless steel, and the difference in melting points between the two materials is significant. During the welding process, the aluminum alloy may melt while the stainless steel remains solid, easily leading to poor weld formation. For example, insufficient weld length may result in low weld strength. Furthermore, at high temperatures, iron-aluminum intermetallic compounds can easily form between the aluminum alloy and stainless steel, reducing the toughness and strength of the joint and resulting in low shear strength and overall low connection strength. Therefore, the welding between valve island 10 and valve components, and between valve island 10 and heat exchanger, is difficult, has low connection strength, is complex, has many weld points, and is difficult to integrate valve island 10, valve components and heat exchanger.

[0101] In this application, the valve island fastener 900 detachably mounts the valve island 10 onto the plate heat exchanger 200, making the connection between the valve island 10 and the plate heat exchanger 200 easy, facilitating the disassembly, repair, or replacement of the valve island 10, and reducing operational difficulty. The connection between the valve island 10 and the plate heat exchanger 200 is less prone to the formation of low-strength intermetallic compounds, making the connection less prone to cracking and resulting in high connection strength between the valve island 10 and the plate heat exchanger 200.

[0102] The fixing component 500 secures the heat exchange device 1000 within the installation space 411. Thus, after the valve island 10 is detachably mounted on the plate heat exchanger 200 via the valve island fastener 900, integrating the plate heat exchanger 200 and the throttle assembly 100, the fixing component 500 secures the heat exchange device 1000 within the installation space 411. This ensures stable support for the heat exchange device 1000 within the installation space 411, suppressing relative displacement and loosening of the heat exchange device 1000 caused by vibrations of other components of the outdoor air conditioning unit 10000 and transportation impacts. It also ensures reliable sealing and stable flow distribution of the refrigerant circuit, thereby improving the overall operational reliability of the outdoor air conditioning unit 10000.

[0103] The valve island fastener 900 and the fixing component 500 are installed and removed in the same direction.

[0104] In some embodiments, the installation and removal direction of the valve island fastener 900 can be understood as the direction in which the valve island fastener 900 can be tightened or loosened using a tool on one side of the heat exchange device 1000. In some embodiments, the installation and removal direction of the valve island fastener 900 can be understood as the axial direction of the valve island fastener 900. For example, if the valve island fastener 900 is a bolt or screw, the installation and removal direction of the valve island fastener 900 is the axial direction of the bolt or screw.

[0105] In some embodiments, the assembly / disassembly direction of the fixing component 500 can be understood as the direction in which the fixing component 500 can be fixed, positioned, overlapped, inserted, or disassembled using a tool or directly from one side of the fixing component 500. In some embodiments, the assembly / disassembly direction of the fixing component 500 can be understood as the snap-fit ​​direction of the fixing component 500, the movement direction that enables snap-fit, the insertion direction, the movement direction that enables insertion, or the axial direction of the fastener of the fixing component 500. For example, the snap-fit ​​direction can be understood as the movement direction of two mating snap-fit ​​components during the snap-fit ​​process; the movement direction that enables snap-fit ​​can be understood as: during the snap-fit ​​operation of two mating components, if one snap-fit ​​component moves in a first direction and then moves in a second direction to achieve snap-fit, then the first direction is the movement direction that enables snap-fit; the insertion direction can be understood as the orientation of the opening of the insertion hole or insertion slot; the axial direction of the fastener of the fixing component 500 can be understood as, if the fastener of the fixing component 500 is a bolt or screw, the axial direction of the fastener of the fixing component 500 is the axial direction of the bolt or screw.

[0106] Understandably, the valve island fastener 900 is used to disassemble and assemble the valve island 10 and the plate heat exchanger 200, and the fixing component 500 is used to fix the heat exchange device 1000 in the installation space 411. By having the valve island fastener 900 and the fixing component 500 disassemble and assemble in the same direction, the disassembly and assembly directions of the valve island 10 and the plate heat exchanger 200 are aligned with the overall disassembly and assembly direction of the heat exchange device 1000. This allows for disassembly and assembly on the same side, with a single, non-detour operation path. It eliminates the need to go to the opposite side or flip parts, reducing the risk of interference and misassembly caused by multi-directional operations, improving disassembly and assembly efficiency, and facilitating installation, maintenance, and replacement.

[0107] For example, when valve island 10 needs to be disassembled, the operator can loosen the valve island fasteners 900 sequentially along the disassembly direction on the same side and remove valve island 10 in a straight forward and backward motion. The fixing component 500 does not need to be loosened or removed, and the plate heat exchanger 200 remains in its original position. After valve island 10 has been replaced or repaired, valve island 10 can be put back in place along the same direction and the valve island fasteners 900 can be tightened to restore it. There is no need to cooperate on the opposite side or flip the parts, avoiding interference with adjacent air ducts, wiring harnesses and pipelines, shortening downtime and improving maintenance efficiency.

[0108] According to an embodiment of the present invention, the outdoor unit 10000 of the air conditioner has a casing 4000 forming an installation space 411. The heat exchange device 1000 is installed in the installation space 411 and includes a plate heat exchanger 200, a throttling device assembly 100, and a valve island fastener 900. The throttling device assembly 100 includes a valve island 10. The valve island 10 is detachably installed in the plate heat exchanger 200 by the valve island fastener 900, so that the plate heat exchanger 200 and the throttling device assembly 100 are integrated, thereby improving the structural compactness between the plate heat exchanger 200 and the throttling device assembly 100, reducing the installation space 411 occupied by the heat exchange device 1000, and fixing the heat exchange device 1000 in the installation space 411 by the fixing component 500, ensuring that the heat exchange device 1000 is stably supported in the installation space 411, and improving the overall operational reliability of the outdoor unit 10000. Meanwhile, by having the valve island fastener 900 and the fixing component 500 oriented to the same side for disassembly and assembly, disassembly and assembly can be performed on the same side. The operation path is simple and does not require detours. There is no need to go around to the other side or flip the parts, which reduces the risk of interference and misassembly caused by multi-directional operation and improves disassembly and assembly efficiency.

[0109] In some embodiments of this utility model, such as Figure 4 , Figure 8 and Figure 11 As shown, the housing 4000 has a fixed surface 401 inside, and the fixed surface 401 and the valve island 10 are located on opposite sides of the plate heat exchanger 200. The plate heat exchanger 200 abuts against and / or is supported by the fixed surface 401.

[0110] Therefore, with the fixed surface 401 and the valve island 10 located on opposite sides of the plate heat exchanger 200, the plate heat exchanger 200 abuts against and / or is supported on the fixed surface 401, so that the throttling device assembly 100 is installed on one side of the plate heat exchanger 200, and the other side is supported and fixed by the fixed component 500 cooperating with the fixed surface 401. This avoids mutual interference between the fixed component 500 and the throttling device assembly 100, making the overall structure of the heat exchange device 1000 composed of the plate heat exchanger 200 and the throttling device assembly 100 more compact and reasonable, effectively optimizing the spatial layout of the air conditioner outdoor unit 10000, and reducing the volume of the air conditioner outdoor unit 10000.

[0111] It should be noted that the fixing surface 401 is formed on the housing 4000 or the fixing component 500, and the specific implementation method is described in detail below.

[0112] In some embodiments of this utility model, the fixed surface 401, the plate heat exchanger 200, and the valve island 10 are arranged along the front-back direction of the outdoor unit 10000 or the left-right direction of the outdoor unit 10000.

[0113] It is understandable that, such as Figures 1-5As shown, when the fixed surface 401, plate heat exchanger 200 and valve island 10 are arranged along the front and rear direction of the outdoor unit 10000, the valve island fastener 900 is installed and removed in the front and rear direction. When it is necessary to disassemble or install the entire heat exchange device 1000 or the valve island 10, only the front panel 412 or the rear panel 413 of the housing 4000 needs to be removed.

[0114] like Figure 1 , Figure 2 and Figures 6-9 As shown, when the fixed surface 401, plate heat exchanger 200, and valve island 10 are arranged along the left-right direction of the outdoor unit 10000, the valve island fastener 900 is installed and removed in the left-right direction. When it is necessary to disassemble or install the entire heat exchange device 1000 or the valve island 10, only the side plate of the casing 4000 needs to be removed. Thus, this arrangement forms an operating path along the front-back direction or the left-right direction of the outdoor unit 10000. The installation and removal directions of the valve island fastener 900 and the fixed component 500 are on the same side, thereby obtaining a clear approach path and higher installation and removal efficiency in different installation scenarios.

[0115] In some embodiments of this utility model, such as Figures 1-5 As shown, when the fixed surface 401, the plate heat exchanger 200, and the valve island 10 are along the front-rear direction of the outdoor unit 10000, the fixed surface 401 is formed on the rear side plate 413 of the housing 4000 or the fixed assembly 500.

[0116] It is understandable that when the fixing surface 401 is formed on the rear side plate 413 of the housing 4000, the valve island 10 is located on the front side of the plate heat exchanger 200. The fixing component 500 cooperates with the fixing surface 401 of the rear side plate 413 to fix the heat exchange device 1000 in the installation space 411. The disassembly and assembly directions of the valve island fastener 900 and the disassembly and assembly directions of the fixing component 500 are in the same direction, which is the front-rear direction. When it is necessary to maintain or disassemble the valve island 10, it is only necessary to remove the front panel 412 of the housing 4000 and disassemble the valve island fastener 900 from the front side along the front-rear direction. When it is necessary to maintain or disassemble the heat exchange device 1000 as a whole, it is only necessary to remove the front panel 412 of the housing 4000 and disassemble the fixing component 500 from the front side along the front-rear direction, so that the heat exchange device 1000 as a whole can be pulled out forward or pushed in backward. Since the valve island fastener 900 and the fixing component 500 are installed and removed in the same direction, both of the above operations can be completed on the same side without having to go around to the back or flip the components. Usually, it is also not necessary to remove adjacent air ducts, pipes and wiring harnesses first. The operation path is simple, which improves the efficiency of installation and removal.

[0117] like Figures 3-5As shown, when the fixing surface 401 is formed on the fixing component 500, the fixing component 500 is located on the side of the plate heat exchanger 200 away from the valve island 10 and is connected to the housing 4000 to form the fixing surface 401. The disassembly and assembly directions of the valve island fastener 900 and the fixing component 500 are in the same direction, which is the front-rear direction. When it is necessary to maintain or disassemble the valve island 10, only the front panel 412 of the housing 4000 needs to be removed, and the valve island fastener 900 needs to be disassembled from the front side along the front-rear direction. When it is necessary to maintain or disassemble the entire heat exchange device 1000, only the front panel 412 of the housing 4000 needs to be removed, and the fixing component 500 needs to be disassembled from the front side along the front-rear direction, so that the entire heat exchange device 1000 can be pulled out forward or pushed in backward. Since the valve island 10 and the fixed component 500 are located on opposite sides of the plate heat exchanger 200 and do not obstruct each other, and the disassembly and assembly directions of the two are facing the same side, both of the above operations can be completed on the same side without having to go around to the back or flip the components. The operation path is simple, which improves the disassembly and assembly efficiency.

[0118] In some embodiments of this utility model, such as Figures 6-9 As shown, when the fixed surface 401, plate heat exchanger 200 and valve island 10 are along the left and right direction of the outdoor unit 10000, the housing 4000 includes a partition 42, which divides the installation space 411 into a fan chamber 4112 and a compressor chamber 4111. The heat exchange device 1000 is installed in the compressor chamber 4111. The fixed surface 401 is formed on the partition 42 or the fixed assembly 500 of the housing 4000.

[0119] It is understandable that, such as Figures 6-9 As shown, when the fixing surface 401 is formed on the partition plate 42 of the housing 4000, the valve island 10 is located on the side of the plate heat exchanger 200 facing the side plate of the housing 4000. The partition plate 42 provides a fixing surface 401 on one side and cooperates with the fixing component 500 to fix the heat exchange device 1000 in the compressor cavity 4111. The valve island fastener 900 is installed and removed in the left and right direction. When it is necessary to maintain or disassemble the valve island 10, only the left or right side plate 414 of the housing 4000 needs to be removed, and the valve island fastener 900 is installed and removed from the side in the left and right direction. When it is necessary to maintain or disassemble the entire heat exchange device 1000, only the left or right side plate 414 needs to be removed, and the fixing component 500 is installed and removed from the side in the left and right direction in sequence, so that the entire heat exchange device 1000 is pulled out to the left or pushed in to the right. Since the valve island fastener 900 and the fixing component 500 are installed and removed in the same direction, both types of operations can be completed on the same side without crossing the front and rear air duct areas of the unit or flipping the components. This keeps the air inlet and outlet surfaces of the fan cavity 4112 unobstructed, with a single operation path, reducing interference and improving installation and removal efficiency.

[0120] When the fixed surface 401 is formed on the fixed component 500: the fixed component 500 is located on the side of the plate heat exchanger 200 away from the valve island 10 and is connected to the housing 4000 to form the fixed surface 401. The valve island fastener 900 is installed and removed in the left and right direction. When it is necessary to maintain or disassemble the valve island 10, the valve island fastener 900 is loosened in the left and right direction from the side where the valve island 10 is located, and the valve island 10 is removed and removed in a straight forward and backward motion. The fixed component 500 does not need to be loosened. When it is necessary to maintain or disassemble the heat exchange device 1000 as a whole, the fixed component 500 is loosened in the left and right direction from the same side, and the heat exchange device 1000 is pulled out or pushed in from the side of the compressor cavity 4111. Since the valve island 10 and the fixed component 500 are located on opposite sides of the plate heat exchanger 200 and do not obstruct each other, and the disassembly and assembly directions of the two are the same, there is no need to cross the front and rear air duct areas of the unit or flip the components, keeping the air inlet and outlet surfaces of the fan cavity 4112 unobstructed, the operation path is simple, reducing interference and improving disassembly and assembly efficiency.

[0121] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figures 10-16 As shown, the fixing surface 401 is formed on the fixing component 500. The housing 4000 includes a chassis 415. The outdoor unit 10000 of the air conditioner also includes a support component 3000. The support component 3000 is fixed on the chassis 415. The fixing component 500 is fixedly connected to the housing 4000 through the support component 3000.

[0122] Understandably, the support component 3000 indirectly connects the fixing component 500 to the housing 4000, allowing the installation position and angle of the fixing component 500 to be adjusted according to the actual needs of the heat exchanger 1000. This optimizes the internal layout, improves space utilization, and facilitates subsequent maintenance and component replacement. Simultaneously, the support component 3000, fixed to the chassis 415, directly transmits weight and vibration to the chassis 415, enhancing overall stability, effectively resisting operational vibration and external impacts, and reducing the risk of component damage.

[0123] Furthermore, since the valve island fastener 900 and the fixing component 500 are installed and removed in the same direction, when only the valve island 10 needs to be replaced, the valve island fastener 900 can be installed and removed along one side in the front-back or left-right direction, and the valve island 10 can be moved in and out in a straight line. When the entire heat exchange device 1000 needs to be installed and removed, the fixing component 500 can be installed and removed in the same direction, so that the heat exchange device 1000 can be pulled out or pushed in in the same direction. This achieves a single operation path, avoids detours, reduces interference, and improves installation and removal efficiency.

[0124] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figures 10-16As shown, the outdoor unit 10000 of the air conditioner also includes at least one of a bracket, a gas-liquid separator 5000, a liquid storage tank, a high-pressure tank, and an expansion tank, and the support assembly 3000 includes at least one of a bracket, a gas-liquid separator 5000, a liquid storage tank, a high-pressure tank, and an expansion tank.

[0125] Understandably, when the support component 3000 includes a bracket, the bracket itself has a supporting function, which can provide a reliable force point for the fixing component 500, enhance the rigidity of the entire connection structure, effectively disperse the vibration and stress generated during the operation of the outdoor unit 10000 of the air conditioner, and reduce the possibility of damage to the casing 4000 and internal components due to vibration.

[0126] Meanwhile, since the gas-liquid separator 5000, liquid storage tank, high-pressure tank, and expansion tank typically have a certain weight and volume, incorporating them into the support assembly 3000 utilizes their own weight to increase system stability, making the connection between the fixing assembly 500 and the casing 4000 more secure and reducing shaking and displacement. Furthermore, the structure of the gas-liquid separator 500 and the liquid storage tank can be used to secure the fixing assembly 500 and the heat exchange device 1000, further optimizing the internal layout of the outdoor unit 10000 and improving space utilization.

[0127] In some embodiments, such as Figure 1 and Figure 2As shown, the housing 4000 includes an outer shell 41 and a middle partition 42. The outer shell 41 forms an installation space 411. The outer shell 41 includes a front panel 412, a rear side panel 413, a left side panel (not shown), a right side panel 414, a top panel (not shown), and a chassis 415. The front panel 412 and the rear side panel 413 extend along the left-right direction of the outdoor unit 10000 and are spaced apart in the front-back direction. The left side panel and the right side panel 414 extend along the front-back direction of the outdoor unit 10000 and are spaced apart in the left-right direction. The top panel and the chassis 415 are arranged opposite each other along the vertical direction of the outdoor unit 10000. The left end of the front panel 412 is connected to the front end of the left side panel, the right end is connected to the front end of the right side panel 414, the upper end is connected to the front end of the top panel, and the lower end is connected to the front end of the chassis 415. The rear side panel 413 is connected to the rear end of the left side panel 413, the right side panel 414, the top panel 415, and the chassis 415. The left side panel 413 is connected to the left end of the top panel 414 and the chassis 415 is connected to the right end of the top panel 415. The front panel 412, rear side panel 413, left side panel 414, right side panel 414, top panel 415, and chassis 415 form an installation space 411. A partition 42 is installed within the installation space 411. The upper end of the partition 42 is connected to the top panel, the lower end to the chassis 415, the front end to the front panel 412, and the rear end to the rear side panel 413. The partition 42, located between the left and right side panels 414, divides the installation space 411 into a fan chamber 4112 and a compressor chamber 4111.

[0128] In some embodiments of this utility model, such as Figure 4 , Figure 5 , Figure 8 , Figure 11 and Figures 21-25 As shown, the fixing assembly 500 includes a fixing bracket 51 and a fixing member 52. A fixing surface 401 is formed on the fixing bracket 51 or the fixing bracket 51 and the fixing surface 401 are connected. The fixing bracket 51 is located on the side of the plate heat exchanger 200 away from the valve island 10. The fixing member 52 is connected to the fixing bracket 51 and defines a fixing space. The plate heat exchanger 200 passes through the fixing space.

[0129] Therefore, once the plate heat exchanger 200 is installed in the fixed space, it is securely positioned within the fixed space by the fastener 52, thus maintaining a stable installation state during the operation of the heat exchange device 1000. Furthermore, the installation of the heat exchange device 1000 is simple, effectively improving assembly efficiency. Simultaneously, to optimize the spatial layout of the heat exchange assembly, the fixing bracket 51 is located on the side of the plate heat exchanger 200 away from the throttling device assembly 100. This allows the throttling device assembly 100 to be installed on one side of the plate heat exchanger 200, while the other side is supported and fixed by the fixing bracket 51. This avoids interference between the fixing bracket 51 and the throttling device assembly 100, making the overall structure of the heat exchange assembly more compact and rational, and reducing the space occupied by the heat exchange assembly.

[0130] In addition, such as Figure 4 and Figure 11 As shown, when the fixing surface 401 is formed on the fixing bracket 51, the fixing bracket 51 is connected to the housing 4000; or, as Figure 8 As shown, when the fixing surface 401 is formed on the housing 4000, the fixing bracket 51 is connected to the fixing surface 401, thereby making full use of the structure of the housing 4000 of the outdoor air conditioner 10000 to support and fix the plate heat exchanger 200. This has the advantages of high structural utilization and reduced additional parts. Moreover, the heat exchange assembly can be easily fixed and installed on external structures such as the outdoor air conditioner 10000, which greatly improves the convenience of installation.

[0131] In some embodiments of this utility model, such as Figures 22-24 , Figure 27 and Figure 28 As shown, the fixing member 52 includes a first cover portion 521 and a fixing portion 522. The first cover portion 521 is located on the side of the plate heat exchanger 200 opposite to the fixing bracket 51, and the first cover portion 521 extends along the width direction of the plate heat exchanger 200 (e.g., ...). Figure 23 Extending in the second direction shown, the fixing part 522 includes two parts and is respectively connected to both ends of the first covering part 521 in the length direction. The fixing part 522 is connected to the fixing bracket 51, and the first covering part 521, the two fixing parts 522 and the fixing bracket 51 form a fixing space.

[0132] Thus, the first covering part 521 covers the plate heat exchanger 200 from the side away from the fixed support 51, and the two fixing parts 522 transfer the load to the fixed support 51, thereby limiting the plate heat exchanger 200. The first covering part 521, the two fixing parts 522 and the fixed support 51 together form a fixed space, so that the plate heat exchanger 200 passes through the fixed space, further improving the installation stability and displacement resistance of the heat exchange device 1000 under operating vibration conditions.

[0133] In some embodiments of this utility model, the distance between the first covering portion 521 and the plate heat exchanger 200 along the thickness direction of the plate heat exchanger 200 is T, and satisfies 0≤T≤2mm; or, the two ends of the length direction of the first covering portion 521 extend beyond the two ends of the width direction of the plate heat exchanger 200 respectively.

[0134] It is understandable that when the distance between the first cover portion 521 and the plate heat exchanger 200 is 0 along the thickness direction of the plate heat exchanger 200, the first cover portion 521 is in contact with the plate heat exchanger 200, thereby improving the frictional limiting and anti-shaking ability of the fixing member 52 on the plate heat exchanger 200. At this time, the two ends of the length direction of the first cover portion 521 extend beyond the two ends of the width direction of the plate heat exchanger 200, so that there are gaps between the two fixing parts 522 connected to the two ends of the length direction of the first cover portion 521 and the plate heat exchanger 200, thereby reducing the noise generated by the contact between the plate heat exchanger 200 and the fixing part 522 under the vibration condition of operation.

[0135] Meanwhile, when the distance between the first cover 521 and the plate heat exchanger 200 along the thickness direction of the plate heat exchanger 200 is 0 < T ≤ 2 mm, a gap is created between the first cover 521 and the plate heat exchanger 200, thereby reducing the noise generated by the contact between the plate heat exchanger 200 and the fixing part 522 under operating vibration conditions. At this time, the length dimension of the first cover 521 is the same as the width dimension of the plate heat exchanger 200, so that the two fixing parts 522 connected to both ends of the length direction of the first cover 521 respectively fit into the plate heat exchanger 200, thereby improving the friction limiting and anti-shaking ability of the fixing part 52 on the plate heat exchanger 200.

[0136] In some embodiments of this utility model, such as Figures 22-24 , Figure 27 and Figure 28 As shown, the fixing part 522 includes a second cover part 5221 and a connecting part 5222. The second cover part 5221 extends along the thickness direction of the plate heat exchanger 200 and one end is connected to the first cover part 521. One end of the connecting part 5222 is connected to the end of the second cover part 5221 away from the first cover part 521. The other ends of the two connecting parts 5222 extend in a direction away from each other. The connecting part 5222 is connected to the fixing bracket 51.

[0137] Thus, the first covering part 521 provides coverage to the plate heat exchanger 200 on the side away from the fixed support 51, and the two second covering parts 5221 provide lateral enclosure on both sides of the plate heat exchanger 200 in the width direction, and the two connecting parts 5222 symmetrically transfer the load to the fixed support 51, forming a mechanical closed-loop structure. This achieves simultaneous limiting in the thickness and width directions of the plate heat exchanger 200, effectively suppressing the shaking and relative displacement of the heat exchange device 1000 during operation, and improving the reliability of the heat exchange device 1000 and the outdoor unit 10000 of the air conditioner.

[0138] In some embodiments of this utility model, such as Figure 22 and Figures 25-30 As shown, the two ends of the fixing member 52 along the width direction of the plate heat exchanger 200 are connected to the fixing bracket 51 by fasteners. This arrangement achieves a secure connection between the fixing member 52 and the fixing bracket 51, thereby ensuring the reliability of the fixed space defined by the fixing member 52 and the fixing bracket 51, and thus guaranteeing the stability of the heat exchange device 1000 during operation.

[0139] Furthermore, both connecting parts 5222 have a first mounting hole 5223, and the fixing bracket 51 has a second mounting hole 512 opposite to the first mounting hole 5223. Fasteners are inserted into the corresponding first mounting hole 5223 and second mounting hole 512 to achieve a tight connection between the fixing member 52 and the fixing bracket 51.

[0140] In some embodiments of this utility model, such as Figure 22 and Figures 25-30 As shown, the fastener 52 has hooks 5224 at both ends along the width direction of the plate heat exchanger 200, and the fixing bracket 51 has a hanging groove 513 that mates with the hooks 5224. Thus, during the assembly of the fixing assembly, by aligning the hooks 5224 of the fastener 52 with the hanging groove 513 of the fixing bracket 51 and inserting them, and making the hooks 5224 and the hanging groove 513 self-locking, the fastener 52 and the fixing bracket 51 are initially positioned and fixed, and the groove wall of the hanging groove 513 provides surface support for the hooks 5224, which can limit the relative displacement of the plate heat exchanger 200 in the width direction and the thickness direction.

[0141] Meanwhile, the hook 5224 and the hanging groove 513 do not require additional fasteners, resulting in a short assembly cycle and fewer steps. After the fixing part 52 and the fixed bracket 51 are initially positioned and fixed, the fixing part 52 is connected to the fixed bracket 51 at both ends along the width direction of the plate heat exchanger 200 by fasteners, thus achieving a tight connection between the fixing part 52 and the fixed bracket 51.

[0142] Furthermore, the two connecting parts 5222 have hooks 5224 at their opposite ends, the hooks 5224 extending along the thickness direction of the plate heat exchanger 200 toward the direction away from the throttle assembly 100, so that the two hooks 5224 can be inserted into the corresponding hanging slots 513.

[0143] In some embodiments of this utility model, the fixed bracket 51 includes a first positioning structure. The plate heat exchanger 200 is positioned and mounted on the side facing away from the valve island 10 on the first positioning structure, which includes a positioning groove. This arrangement connects the plate heat exchanger 200 and the fixed bracket 51. Furthermore, the positioning groove in the first positioning structure allows the side of the plate heat exchanger 200 facing away from the valve island 10 to engage with the positioning groove, achieving pre-positioning and reducing assembly difficulty.

[0144] In some embodiments of this utility model, the fixed bracket 51 includes a support plate, which is supported below the plate heat exchanger 200. Thus, by supporting the plate heat exchanger 200 below, the support plate further supports the plate heat exchanger 200 after it is installed within the fixed space, ensuring the stability of the plate heat exchanger 200 and improving the reliability of the heat exchange device 1000.

[0145] In some embodiments of this utility model, such as Figure 27 and Figure 28 As shown, the fastener 52 is a single piece. This design improves the overall rigidity and fatigue resistance of the fastener 52, enabling it to maintain a stable clamping force on the plate heat exchanger 200 under vibration and other conditions, thus enhancing overall reliability. Simultaneously, the integrated design reduces the number of parts and process costs, facilitating collaborative design with the mold and process of the mounting bracket 51, further improving the compactness and manufacturability of the heat exchange device 1000 and the outdoor air conditioning unit 10000.

[0146] Specifically, the fastener 52 is integrally formed from a metal sheet by stamping and bending, so that the first cover 521, the two second cover parts 5221 and the two connecting parts 5222 are made as a whole without secondary assembly.

[0147] In some embodiments of this utility model, the plate heat exchanger 200 includes a heat exchange body 210, which includes a plurality of stacked heat exchange plates and a first plate 240 and a second plate 250 disposed on both sides of the heat exchange plates. The first plate 240 includes a flat portion 260, on which the valve island 10 is disposed, and the fixing member 52 is fixedly connected to the second plate 250. Thus, the plate heat exchanger 200 and the fixing assembly 300 are connected by the fixing member 52 and the second plate 250, thereby fixing the plate heat exchanger 200. Furthermore, by placing the first plate 240 and the second plate 250 on opposite sides of the heat exchange plates, the valve island 10 and the fixing member 52 are located on opposite sides of the heat exchange plates, reducing interference between them.

[0148] In some embodiments of this utility model, such as Figures 32-39 As shown, the plate heat exchanger 200 has a first heat exchange channel 220 and a second heat exchange channel 230 that are separated from each other and exchange heat with each other. The plate heat exchanger 200 has a first interface 2202, a second interface 2201, a third interface 2301 and a fourth interface 2302 on the side away from the fixed support 51. The first interface 2202 and the second interface 2201 are connected to the first heat exchange channel 220, and the third interface 2301 and the fourth interface 2302 are connected to the second heat exchange channel 230.

[0149] It is understood that one of the first interface 2202 and the second interface 2201 serves as the inlet of the first heat exchange channel 220 and the other as the outlet of the first heat exchange channel 220, so that the heat exchange medium can flow into the first heat exchange channel 220 and flow out after heat exchange. Similarly, one of the third interface 2301 and the fourth interface 2302 serves as the inlet of the second heat exchange channel 230 and the other as the outlet of the second heat exchange channel 230, so that the heat exchange medium can flow into the second heat exchange channel 230 and flow out after heat exchange. Thus, through the first heat exchange channel 220 and the second heat exchange channel 230, two heat exchange media of different temperatures can flow through the plate heat exchanger 200 simultaneously. These two heat exchange media of different temperatures can exchange heat with each other, and the direction of heat exchange medium flow can be changed according to whether the air conditioning system is in heating mode or cooling mode.

[0150] The first interface 2202 and the fourth interface 2302 are along the length of the plate heat exchanger 200 (e.g., ...). Figure 23 and Figure 30 The same end of the plate heat exchanger 200 (as shown in the third direction) and along the width direction of the plate heat exchanger 200 (e.g. Figure 23 and Figure 30As shown in the second direction, the second interface 2201 and the third interface 2301 are arranged at the same end in the length direction of the plate heat exchanger 200 and along the width direction of the plate heat exchanger 200. The first interface 2202 and the second interface 2201 are at the same end in the width direction of the plate heat exchanger 200, and the third interface 2301 and the fourth interface 2302 are at the same end in the width direction of the plate heat exchanger 200. This arrangement makes the layout of the first interface 2202, the second interface 2201, the third interface 2301 and the fourth interface 2302 reasonable, and leaves sufficient operating space around each interface, making pipeline connection and overall assembly more convenient.

[0151] Because a fixed space is formed between the fixing member 52 and the fixed support for the heat exchange device 1000 to pass through, at least a portion of the fixing member 52 is positioned between the first interface 2202 and the second interface 2201 and between the third interface 2301 and the fourth interface 2302 along the length direction of the plate heat exchanger 200. This allows the fixing member 52 to avoid the locations of the first interface 2202, the second interface 2201, the third interface 2301, and the fourth interface 2302, thus preventing obstruction or interference with the connection of the pipes at the interfaces. Furthermore, compared to placing the fixed structure at the corners of the plate heat exchanger 200, this application, by positioning the fixing member 52 between the first interface 2202, the second interface 2201, and the third interface 2301 and the fourth interface 2302, can firmly press the plate heat exchanger 200 onto the fixed support 51, effectively improving the stability and vibration resistance of the entire heat exchange device 1000.

[0152] In some embodiments of this utility model, such as Figure 33 , Figure 36 , Figure 40 As shown, the outdoor unit 10000 of the air conditioner also includes a compressor 2100. Along the length of the plate heat exchanger 200, the fixing member 52 is located on the side of the throttling assembly 100 opposite to the compressor 2100. It is understood that the throttling assembly 100 has a refrigerant channel communicating with the first heat exchange channel 220 and the second heat exchange channel 230. The throttling assembly 100 is connected to the compressor 2100 so that the heat exchange medium can be delivered from the compressor 2100 to the refrigerant channel of the throttling assembly 100 or from the refrigerant channel of the throttling assembly 100 to the compressor 2100.

[0153] Therefore, along the length of the plate heat exchanger 200, the fastener 52 is located on the side of the throttle assembly 100 away from the compressor 2100, which can shorten the distance between the compressor 2100 and the throttle assembly 100, thereby shortening the distance between the connecting pipes between the two and further optimizing the overall layout of the heat exchange device 1000.

[0154] In some embodiments of this utility model, such as Figures 21-24As shown, the throttle assembly 100 also includes a valve. A refrigerant flow channel is formed within the valve island 10, and the refrigerant flow channel communicates with the heat exchange flow channel of the plate heat exchanger 200. The valve is disposed on the valve island 10 and communicates with the refrigerant flow channel. Thus, by communicating the refrigerant flow channel of the throttle assembly 100 with the heat exchange flow channel of the plate heat exchanger 200, the throttle assembly 100 is connected to the compressor 2100 so that the heat exchange medium can be delivered from the compressor 2100 to the refrigerant flow channel of the throttle assembly 100 or from the refrigerant flow channel of the throttle assembly 100 to the compressor 2100.

[0155] At least one of the sides of the plate heat exchanger 200 facing away from the throttle assembly 100 and the side of the plate heat exchanger 200 closest to the throttle assembly 100 is supported by the fixing assembly 500, making it easy for the heat exchange device 1000 to be installed in the installation space 411 via the fixing assembly 500 and facilitating the adjustment of the valve orientation, thereby ensuring that the axial direction of the valve and / or the movement direction of the valve core is perpendicular to the direction of gravity (e.g., ...). Figure 2 The angle between the vertical and horizontal directions shown is ω1, and satisfies 0°≤ω1≤45°.

[0156] This application relates the axial direction of the valve and / or the movement direction of the valve core to the direction of gravity (e.g., ...). Figure 2 The included angle (in the up and down directions shown) is ω1, and satisfies 0°≤ω1≤45°. While the valve core can realize at least one of the following: opening, closing, flow regulation, and throttling opening regulation of the refrigerant flow path, the force (support force against the gravity of the valve core) on the same or adjacent circumferential surfaces of the valve core is more evenly distributed. During operation, the wear on the same or adjacent circumferential surfaces of the valve core is more even, avoiding excessive local wear of the valve core, improving the operational reliability and life of the valve components, reducing noise, and thus improving the reliability of the heat exchange device 1000.

[0157] It should be noted that ω1 can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, or 45°. Preferably, ω1 is 0°-30°, and more preferably, ω1 is 0°-15°.

[0158] It should be noted that valves are used to control the flow rate and pressure of the heat exchange medium flowing through them, in order to achieve precise regulation of the heat exchange medium flow. For example, valves can throttle and reduce the pressure of the heat exchange medium flowing through them, thereby lowering the temperature and humidity of the heat exchange medium. Specifically, the valve is an electronic expansion valve, which includes a valve body and a valve core. The valve body forms a throttling channel communicating with the valve cavity, and at least a portion of the valve core is movably disposed within the throttling channel. Of course, the valve can also be a thermostatic expansion valve or other types of throttling devices.

[0159] Valve island 10 is fixed to plate heat exchanger 200 and located on one side of plate heat exchanger 200 in the thickness direction. The refrigerant flow channel is connected to the heat exchange flow channel of plate heat exchanger 200. Valve components are installed on valve island 10 and connected to refrigerant flow channel. Heat exchange device 1000 is installed in installation space 411. Fixing component 500 fixes heat exchange device 1000 in installation space 411. The side of plate heat exchanger 200 away from throttling device assembly 100 is supported by fixing component 500, so that plate heat exchanger 200 and throttling device assembly 100 are integrated, and mutual interference between fixing component 500 and throttling device assembly 100 is avoided. This makes the overall structure of plate heat exchanger 200 and throttling device assembly 100 more compact and reasonable, effectively optimizing the spatial layout of air conditioner outdoor unit 10000 and reducing the volume of air conditioner outdoor unit 10000. Meanwhile, by making the angle between the axial direction of the valve and / or the movement direction of the valve core and the direction of gravity ω1, where 0°≤ω1≤45°, the wear of the valve core can be reduced during operation, thereby improving the operational reliability and lifespan of the valve and reducing noise, thus improving the reliability of the outdoor unit 10000 of the air conditioner.

[0160] The axial direction of a valve component can be understood as: the axial direction of the valve core and the axial direction of the valve cavity in which the valve component is mounted. The direction of movement of the valve core can be understood as: the linear direction of movement excluding the rotation of the valve core.

[0161] In some embodiments of this utility model, such as Figure 32 As shown, valve island 10 is located at the second interface 2201 and the third interface 2301. Both the second interface 2201 and the third interface 2301 are connected to the refrigerant flow channel. One end of the valve is located on valve island 10, and the other end of the valve extends toward the fourth interface 2302. The valve is located between the two ends in the length direction of plate heat exchanger 200.

[0162] It is understandable that, since the first interface 2202 and the fourth interface 2302 are arranged at the same end in the length direction of the plate heat exchanger 200 and along the width direction of the plate heat exchanger 200, and the second interface 2201 and the third interface 2301 are arranged at the same end in the length direction of the plate heat exchanger 200 and along the width direction of the plate heat exchanger 200, the valve provided on the valve island 10 is located between the two ends in the length direction of the plate heat exchanger 200, and the other end of the valve extends toward the fourth interface 2302, thereby achieving a further optimized layout and making the overall structure of the heat exchange device 1000 more compact.

[0163] In some embodiments of this utility model, such as Figures 21-24 and Figure 32As shown, an installation gap is formed between the surface of the plate heat exchanger 200 near the valve island 10 and the valve and / or valve island 10, and at least a portion of the fixing member 52 is accommodated within the installation gap. Therefore, during the installation of the fixing member 52, the installation gap between the surface of the plate heat exchanger 200 near the valve island 10 and the valve and / or valve island facilitates one end of the fixing member 52 passing through the installation gap and connecting to the fixing bracket 51, thereby reducing assembly difficulty and improving assembly efficiency.

[0164] In some embodiments of this utility model, such as Figures 21-24 and Figure 32 As shown, an installation gap is formed between the surface of the plate heat exchanger 200 near the valve island 10 and the valve and / or valve island 10. The maximum width of the fixing member 52 along the length of the plate heat exchanger 200 is greater than the distance between the end of the valve near the fourth interface 2302 and the fourth interface 2302. Therefore, during the installation of the fixing member 52, the installation gap between the surface of the plate heat exchanger 200 near the valve island 10 and the valve and / or valve island 10 facilitates one end of the fixing member 52 to pass through the installation gap and connect to the fixing bracket 51, thereby reducing assembly difficulty and improving assembly efficiency.

[0165] In some embodiments of this utility model, the plate heat exchanger 200 is arranged vertically or inclined, with the first interface 2202 and the fourth interface 2302 located above or obliquely above the second interface 2201 and the third interface 2301. The length direction of the plate heat exchanger 200 is perpendicular to the direction of gravity (e.g., Figure 2 The angle between the vertical direction shown is ω2, 0°≤ω2≤30°; and / or, the angle between the axial direction of the valve and / or the direction of movement of the valve core and the direction of gravity is ω1, 0°≤ω1≤30°.

[0166] It is understandable that when the plate heat exchanger 200 is set vertically or at an angle, the first interface 2202 and the fourth interface 2302 are located above or diagonally above the second interface 2201 and the third interface 2301. This arrangement of the first interface 2202 and the fourth interface 2302 in the vertical direction, and the second interface 2201 and the third interface 2301 in the vertical direction, further optimizes the spatial layout of the plate heat exchanger 200 and facilitates the flow of refrigerant in the heat exchange path.

[0167] Meanwhile, since the valve island 10 is located at the second interface 2201 and the third interface 2301, both of which are connected to the refrigerant flow path, one end of the valve is located on the valve island 10, and the other end of the valve extends toward the fourth interface 2302. The valve is located between the two ends of the plate heat exchanger 200 along its length. By limiting the angle between the length direction of the plate heat exchanger 200 and the direction of gravity to between 0 and 30°, at least one of the following can be achieved through the valve core: opening, closing, flow regulation, and throttling opening regulation of the refrigerant flow path. At the same time, the force (support force against the gravity of the valve core) on the same circumferential surface or adjacent circumferential surfaces of the valve core is more evenly distributed. During operation, the wear on the same circumferential surface or adjacent circumferential surfaces of the valve core is more even, avoiding excessive local wear of the valve core, improving the operational reliability and life of the valve, reducing noise, and thus improving the reliability of the heat exchange device 1000.

[0168] It should be noted that ω2 can be 0°, 5°, 10°, 15°, 20°, 25°, or 30°. Preferably, ω2 is 0°-30°, and more preferably, ω2 is 0°-15°.

[0169] At the same time, the axial direction of the valve and / or the movement direction of the valve core are considered in relation to the direction of gravity (e.g., Figure 2 The included angle (in the up and down directions shown) is ω1, and satisfies 0°≤ω1≤45°. While the valve core can realize at least one of the following: opening, closing, flow regulation, and throttling opening regulation of the refrigerant flow path, the force (support force against the gravity of the valve core) on the same or adjacent circumferential surfaces of the valve core is more evenly distributed. During operation, the wear on the same or adjacent circumferential surfaces of the valve core is more even, avoiding excessive local wear of the valve core, improving the operational reliability and life of the valve components, reducing noise, and thus improving the reliability of the heat exchange device 1000.

[0170] In some embodiments of this utility model, such as Figures 32-39 As shown, the throttle assembly 100 includes a valve island 10, which has the refrigerant flow channel and a first flow channel port 1001, a second flow channel port 1002, and a third flow channel port 1003 respectively connected to the refrigerant flow channel. The second flow channel port 1002 is connected to a second interface 2201, and the third flow channel port 1003 is connected to a third interface 2301. Thus, this arrangement allows the refrigerant flow channel of the valve island 10 to be connected to the first heat exchange flow channel 220 via the second flow channel port 1002 and the second interface 2201, and to the second heat exchange flow channel 230 via the third flow channel port 1003 and the third interface 2301.

[0171] like Figures 21-25 and Figure 32As shown, the outdoor unit 10000 of the air conditioner also includes a first connecting pipe 600, a second connecting pipe 700, and a third connecting pipe 800. One end of the first connecting pipe 600 is connected to the first interface 2202, one end of the second connecting pipe 700 is connected to the fourth interface 2302, and one end of the third connecting pipe 800 is connected to the first flow channel 1001.

[0172] It is understood that the first connecting pipe 600 is connected to the compressor 2100 at the end opposite to the first interface 2202, so that the first heat exchange channel 220 can exchange heat exchange medium with the compressor 2100 through the first connecting pipe 600. The second connecting pipe 700 is connected to the compressor 2100 at the end opposite to the fourth interface 2302, so that the second heat exchange channel 230 can exchange heat exchange medium with the compressor 2100 through the second connecting pipe 700. The third connecting pipe 800 is connected to the compressor 2100 at the end opposite to the first channel opening 1001, so that the refrigerant channel in the valve island 10 can exchange heat exchange medium with the compressor 2100 through the third connecting pipe 800.

[0173] The first connecting pipe 600 extends in the same direction from the end opposite to the first interface 2202, the second connecting pipe 700 extends in the same direction from the end opposite to the fourth interface 2302, and the third connecting pipe 800 extends in the same direction from the end opposite to the first flow channel opening 1001. Thus, by arranging the ends of the first connecting pipe 600 (away from the first interface 2202), the second connecting pipe 700 (away from the fourth interface 2302), and the third connecting pipe 800 (away from the first flow channel opening 1001) in the same direction, a unidirectional outgoing line can be formed between the heat exchanger 1000 and the compressor 2100. This facilitates the welding connection between the first connecting pipe 600, the second connecting pipe 700, and the third connecting pipe 800 and the compressor 2100, effectively shortens the pipe length, reduces the operational difficulty of the assembly station and the stress concentration of the weld, further improves the compactness of the layout, and facilitates subsequent maintenance.

[0174] In some embodiments of this utility model, the outdoor unit 10000 of the air conditioner includes a compressor 2100, a first connecting pipe 600 extending away from the first interface 2202, a second connecting pipe 700 extending away from the fourth interface 2302, and a third connecting pipe 800 extending away from the first flow channel 1001 toward the side where the compressor 2100 is located.

[0175] Therefore, by extending the first connecting pipe 600 away from the first interface 2202, the second connecting pipe 700 away from the fourth interface 2302, and the third connecting pipe 800 away from the first flow channel 1001 towards the compressor 2100, on the one hand, the pipe bends and crossings to the compressor 2100 are reduced, the effective length of the pipe is shortened, and the friction resistance and local resistance are reduced. On the other hand, the first flow channel 1001, the second flow channel 1002, and the third flow channel 1003 form the same-side outlet direction near the compressor 2100, which facilitates the same-side welding, insulation and leakage detection around the compressor 2100, reduces the difficulty, and improves the consistency of the weld and the reliability of the seal.

[0176] In some embodiments of this utility model, such as Figures 21-25 As shown, at least one of the first connecting pipe 600 and the second connecting pipe 700 includes a first segment 61 and a second segment 62. The first segment 61 extends along the thickness direction of the plate heat exchanger 200, and one end of the first segment 61 is connected to the first interface 2202 or the fourth interface 2302. One end of the second segment 62 is connected to the other end of the first segment 61. Along the thickness direction of the plate heat exchanger 200, the second segment 62 is located on the side of the throttling device assembly 100 away from the plate heat exchanger 200 and is spaced apart from the throttling device assembly 100.

[0177] It is understandable that, since the end of the first connecting pipe 600 away from the first interface 2202, the end of the second connecting pipe 700 away from the fourth interface 2302, and the end of the third connecting pipe 800 away from the first flow channel 1001 all extend in the same direction, one end of the first connecting pipe 600 is connected to the first interface 2202, one end of the second connecting pipe 700 is connected to the fourth interface 2302, the second flow channel 1002 of the valve island 10 is connected to the second interface 2201, and the third flow channel 1003 of the valve island 10 is connected to the third interface 2301, in order to avoid the first connecting pipe 600 and Interference between the second connecting pipe 700 and the throttling device assembly 100 is prevented by the first segment 61 extending along the thickness direction of the plate heat exchanger 200, and the second segment 62 located on the side of the throttling device assembly 100 away from the plate heat exchanger 200 and spaced apart from the throttling device assembly 100. This ensures that both the first segment 61 and the second segment 62 are spaced apart from the throttling device assembly 100, thereby avoiding contact friction or mutual interference between the first connecting pipe 600 and the second connecting pipe 700 and the throttling device assembly 100 during assembly and operation, and reducing wear and noise caused by vibration.

[0178] In some embodiments of this invention, the second segment 62 extends along a straight line or a curve. Thus, as... Figures 21-25As shown, the second segment 62 of the second connecting pipe 700 extends in a straight line, passing over the throttle assembly 100 with minimal bends, so as to shorten the path of the second segment 62, reduce pressure, and simplify processing and assembly; or, in another case, as Figures 21-25 As shown, the second segment 62 of the first connecting pipe 600 extends along a curve, avoiding the local protrusions of the throttle assembly 100 in a conformal manner and with a suitable bending radius, which can reduce stress concentration and fatigue risk at the weld. Thus, by extending the second segment 62 in a straight line or a curve, the gap between the second segment 62 and the throttle assembly 100 is maintained while improving versatility.

[0179] In some embodiments of this utility model, such as Figures 21-25 As shown, at least one of the first connecting pipe 600 and the second connecting pipe 700 further includes a third segment 63 and a fourth segment 64. The third segment 63 extends along the thickness direction of the plate heat exchanger 200, one end of the third segment 63 is connected to the end of the second segment 62 away from the first segment 61, and the other end extends towards the fixed support 51. The fourth segment 64 extends along the length direction of the plate heat exchanger 200, and one end of the fourth segment 64 is connected to the end of the third segment 63 away from the second segment 62.

[0180] Understandably, since the second segment 62 is spaced apart from the throttling device assembly 100 along the thickness direction of the plate heat exchanger 200, the third segment 63 is then bent towards the fixed bracket 51 along the thickness direction of the plate heat exchanger 200. This further avoids interference between the third segment 63 and the throttling device assembly 100, and also reduces the space occupied by the first connecting pipe 600 and the second connecting pipe 700 in the thickness direction of the plate heat exchanger 200. Simultaneously, the fourth segment 64 is arranged along the length direction of the plate heat exchanger 200, forming a straight longitudinal direction, which facilitates connection with the compressor 2100's output wiring, facilitates the installation of the heat exchange device 1000, and reduces assembly difficulty. This ensures the compact arrangement and long-term reliability of the heat exchange device 1000.

[0181] In some embodiments of this utility model, such as Figures 32-39 As shown, the valve island 10 has a first flow channel port 1001, a second flow channel port 1002, and a third flow channel port 1003 that are connected to the refrigerant flow channel. The second flow channel port 1002 is connected to the second interface 2201, and the third flow channel port 1003 is connected to the third interface 2301. The valve island 10 also has a branch valve cavity. The refrigerant flow channel includes a main flow path and a branch flow path. The two ends of the main flow path are connected to the first flow channel port 1001 and the second flow channel port 1002, respectively. The two ends of the branch flow path are connected to the main flow path and the branch valve cavity, respectively. The branch valve cavity is connected to the third flow channel port 1003. The valve includes a branch valve, which is configured to be connected to and communicate with the branch valve cavity.

[0182] Thus, the heat exchange medium can flow sequentially through the first flow channel 1001, the first flow path 101, the first valve chamber 111, the second flow path 102, the second flow channel 1002, and the plate heat exchanger 200, or it can flow sequentially through the first flow channel 1001, the first flow path 101, the first valve chamber 111, the third flow path 103, the second valve chamber 121, the third flow channel 1003, and the plate heat exchanger 200, thereby achieving the connection between the valve 10 and the plate heat exchanger 200.

[0183] In some embodiments of this utility model, such as Figures 32-39 As shown, the valve island 10 also has a first valve chamber 111 and a second valve chamber 121. The refrigerant flow channel includes a first flow path 101, a second flow path 102 and a third flow path 103. The two ends of the first flow path 101 are connected to the first flow channel opening 1001 and the first valve chamber 111, respectively. The two ends of the second flow path 102 are connected to the second flow channel opening 1002 and the first valve chamber 111, respectively. The main flow path includes the first flow path 101, the first valve chamber 111 and the second flow path 102. The two ends of the third flow path 103 are connected to the first valve chamber 111 and the second valve chamber 121, respectively. The second valve chamber 121 is connected to the third flow channel opening 1003. The branch flow path includes the third flow path 103. The branch valve chamber is the second valve chamber 121. The valves include a first valve 20 and a second valve 30. The first valve 20 is configured to be connected and communicate with the first valve chamber 111, the second valve 30 is configured to be connected and communicate with the second valve chamber 121, and the branch valve is the second valve 30.

[0184] Thus, the heat exchange medium can flow sequentially through the first flow channel 1001, the first flow path 101, the first valve chamber 111, the second flow path 102, the second flow channel 1002, and the plate heat exchanger 200, or it can flow sequentially through the first flow channel 1001, the first flow path 101, the first valve chamber 111, the third flow path 103, the second valve chamber 121, the third flow channel 1003, and the plate heat exchanger 200, thereby achieving communication between the first valve 20 and the second valve 30 and the plate heat exchanger 200.

[0185] In some embodiments of this invention, at least one of the main flow path and the branch flow path is formed as a capillary flow path. The equivalent inner diameter of the capillary flow path is less than or equal to 5 mm; and / or, the length of the capillary flow path is greater than or equal to 5 mm.

[0186] In this context, a capillary flow path refers to a pipe with a small equivalent inner diameter, such as an equivalent inner diameter L of less than 5 mm. The capillary flow path can be defined by a circular tube or other shapes, and the equivalent inner diameter refers to the diameter of a circle with the same cross-sectional area as the capillary flow path. For example, in some embodiments, the equivalent inner diameter of the capillary flow path is L, where L ≤ 5 mm. Examples of L values ​​include 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4 mm, 4.5 mm, and 5 mm.

[0187] The smaller inner diameter of the capillary flow path reduces the pressure of the heat exchange medium (such as refrigerant) within it, making it easier for the liquid refrigerant to vaporize. This also reduces the likelihood of gas-liquid two-phase mixing at the outlet, thus minimizing refrigerant noise caused by the two-phase state. Furthermore, the smaller inner diameter accelerates the refrigerant flow rate, resulting in more uniform gas-liquid mixing within the capillary flow path. Smaller, more evenly distributed bubbles further reduce the likelihood of flow blockage, further lowering noise levels within the capillary flow path and consequently reducing noise within the valve island.

[0188] Specifically, in some embodiments, such as Figure 31 and Figure 32 As shown, the throttle assembly 100 has an inlet and an outlet. The inlet is used to input the heat exchange medium into the throttle assembly 100, and the outlet is used to discharge the heat exchange medium from the throttle assembly 100.

[0189] The heat exchanger 1000 has a heating mode and a cooling mode. In cooling mode, the first flow channel 1001 is the inlet, and the second flow channel 1002 and the third flow channel 1003 are both outlets. The heat exchange medium flows into the throttling device assembly 100 from the first flow channel 1001 and flows out of the throttling device assembly 100 from the second flow channel 1002 and the third flow channel 1003 to flow into the first heat exchange channel 220 and the second heat exchange channel 230 of the plate heat exchanger 200, respectively. Specifically, as shown... Figure 31 and Figures 37-39 As shown, Figure 31 The solid arrows indicate the flow direction of the heat exchange medium in the cooling mode. The heat exchange medium flows into the first flow path 101 from the first flow channel port 1001 and passes through the first valve 20. Then it splits into two paths and flows into the second flow path 102 and the third flow path 103. The heat exchange medium flowing into the second flow path 102 flows into the first heat exchange channel 220 of the plate heat exchanger 200 from the second flow channel port 1002. The heat exchange medium flowing into the third flow path 103 passes through the second valve 30 and then flows into the second heat exchange channel 230 of the plate heat exchanger 200 from the third flow channel port 1003.

[0190] In cooling mode, the heat exchange medium flowing into the first heat exchange channel 220 has a lower temperature after being throttled by the first valve 20, and the heat exchange medium flowing into the second heat exchange channel 230 has an even lower temperature after being throttled by the first valve 20 and the second valve 30. After exchanging heat with the lower-temperature heat exchange medium in the first heat exchange channel 220 and the even lower-temperature heat exchange medium in the second heat exchange channel 230, the temperature of the heat exchange medium flowing out of the plate heat exchanger 200 from the first heat exchange channel 220 is even lower, resulting in better heat exchange effect and higher cooling efficiency of the plate heat exchanger 200.

[0191] In heating mode, the second flow channel 1002 is the inlet, and the first flow channel 1001 and the third flow channel 1003 are both outlets. The heat exchange medium flows into the throttling device assembly 100 from the second flow channel 1002 and flows out of the throttling device assembly 100 from the first flow channel 1001 and the third flow channel 1003. The heat exchange medium flowing out of the throttling device assembly 100 from the third flow channel 1003 flows into the second heat exchange channel 230 of the plate heat exchanger 200. Specifically, as... Figure 31 As shown, Figure 31 The dashed arrows indicate the flow direction of the heat exchange medium in the heating mode. The heat exchange medium in the first heat exchange channel 220 flows into the second flow path 102 from the second flow path opening 1002, and then splits into two flows into the first flow path 101 and the third flow path 103. The heat exchange medium flowing into the first flow path 101 flows out from the first flow path opening 1001 after passing through the first valve 20. The heat exchange medium flowing into the third flow path 103 flows into the second heat exchange channel 230 of the plate heat exchanger 200 after passing through the second valve 30 and passing through the third flow path opening 1003.

[0192] In heating mode, the heat exchange medium in the first heat exchange channel 220 is not throttled by the first valve 20 and the second valve 30, while the heat exchange medium in the second heat exchange channel 230 is throttled by the second valve 30 and has a lower temperature. After heat exchange between the higher-temperature heat exchange medium in the first heat exchange channel 220 and the lower-temperature heat exchange medium in the second heat exchange channel 230, the temperature of the heat exchange medium flowing out of the plate heat exchanger 200 from the second heat exchange channel 230 is higher. In the air conditioner 2000, including the heat exchange device 1000, the higher temperature and pressure of the heat exchange medium flowing from the plate heat exchanger 200 into the compressor 2100 is beneficial for increasing the suction volume of the compressor 2100.

[0193] By changing the inlet and outlet of the throttle assembly 100 in cooling and heating modes, the working effect of the heat exchange device 1000 in cooling and heating modes can be improved, which is practical.

[0194] In some embodiments of this utility model, the axial direction of the first valve member 20 and / or the movement direction of the valve core of the first valve member 20 and / or the axial direction of the first valve cavity 111 are opposite to the direction of gravity (e.g., Figure 2The included angle (in the up and down directions shown) is ω11, 0°≤ω11≤30°. Therefore, while the valve core of the first valve component 20 can achieve at least one of the following: opening, closing, flow regulation, and throttling adjustment of the refrigerant flow path, the force (supporting force against the weight of the valve core) on the same or adjacent circumferential surfaces of the first valve component 20 is more evenly distributed. During operation, the wear on the same or adjacent circumferential surfaces of the valve core is more uniform, avoiding excessive local wear of the valve core, improving the operational reliability and lifespan of the valve component, reducing noise, and thus improving the reliability of the heat exchange device 1000.

[0195] It should be noted that ω11 can be 0°, 5°, 10°, 15°, 20°, 25°, or 30°. Preferably, ω11 is 0°-30°, and more preferably, ω11 is 0°-15°.

[0196] In some embodiments of this utility model, the angle between the axial direction of the second valve element 30 (i.e., the branch valve element) and / or the movement direction of the valve core of the second valve element 30 (i.e., the branch valve element) and / or the axial direction of the second valve cavity 121 (i.e., the branch valve cavity) and the direction of gravity is ω11, where 0°≤ω11≤30°. Thus, while at least one of opening, closing, flow regulation, and throttling adjustment of the refrigerant flow path can be achieved through the valve core of the second valve element 30 (i.e., the branch valve element), the force distribution (the supporting force against the gravity of the valve core) on the same or adjacent circumferential surfaces of the valve core of the second valve element 30 is relatively uniform. During operation, the wear on the same or adjacent circumferential surfaces of the valve core of the second valve element 30 is relatively uniform, avoiding excessive local wear of the valve core of the second valve element 30, improving the operational reliability and lifespan of the valve element, reducing noise, and thereby improving the reliability of the heat exchange device 1000.

[0197] It should be noted that ω11 can be 0°, 5°, 10°, 15°, 20°, 25°, or 30°. Preferably, ω11 is 0°-30°, and more preferably, ω11 is 0°-15°.

[0198] In some embodiments of this utility model, such as Figures 32-37 As shown, the angle between the axis of the first valve 20 and the axis of the second valve 30 is α, where 0° ≤ α ≤ 60°. For example, the angle between the projections of the axes of the first valve 20 and the second valve 30 onto the plane containing the end plate of the plate heat exchanger 200 is α. For example, the value of α can be 0°, 5°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, etc.

[0199] If the angle α between the axis of the first valve 20 and the axis of the second valve 30 is too large, it will increase the space occupied by the first valve 20 and the second valve 30 in the width direction of the plate heat exchanger, resulting in a large space occupied by the throttle assembly 100 and making installation more difficult. This application ensures that the angle α satisfies 0°≤a≤60°, which can appropriately reduce the space occupied by the first valve 20 and the second valve 30, making the structure of the throttle assembly 100 more compact and easier to install.

[0200] Furthermore, the first valve component 20 includes a first coil portion 201 and a first valve core 202. The first coil portion 201 is disposed above or diagonally above the first mounting portion 11. The second valve component 30 includes a second coil portion 301 and a second valve core 302. The second coil portion 301 is disposed above or diagonally above the second mounting portion 12. By limiting 0° < a ≤ 60°, the installation of the first coil portion 201 and the second coil portion 301 is facilitated, and the assembly difficulty is reduced.

[0201] In some embodiments, such as Figures 32-37 As shown, the angle between the axis of the first valve chamber 111 and the axis of the second valve chamber 121 is b, where 0° ≤ b ≤ 60°. For example, the angle between the projections of the axes of the first valve chamber 111 and the second valve chamber 121 onto the plane containing the end plate is b. For example, the value of b can be 0°, 5°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, etc. In some specific embodiments, such as... Figure 37 As shown, b = a.

[0202] If the included angle b between the axis of the first valve chamber 111 and the axis of the second valve chamber 121 is too large, it will increase the space occupied by the first valve chamber 111 and the second valve chamber 121 in the width direction of the plate heat exchanger, resulting in a large space occupied by the valve island 10 and a large overall volume of the throttle assembly 100, making installation more difficult. This application ensures that the included angle b satisfies 0°≤b≤60°, which can appropriately reduce the space occupied by the first valve chamber 111 and the second valve chamber 121, making the structure of the valve island 10 more compact and the overall structure of the throttle assembly 100 more compact, thus facilitating installation.

[0203] Furthermore, the first valve component 20 includes a first coil portion 201 and a first valve core 202, with the first coil portion 201 disposed above or diagonally above the first valve core 202. The second valve component 30 includes a second coil portion 301 and a second valve core 302, with the second coil portion 301 disposed above or diagonally above the second valve core 302. By limiting 0° < b ≤ 60°, the installation of the first coil portion 201 and the second coil portion 301 is facilitated, reducing assembly difficulty.

[0204] In some embodiments of this utility model, such as Figures 32-38As shown, a fourth flow path 104 for the flow of heat exchange medium is also defined within the valve island 10. The two ends of the fourth flow path 104 are connected to the second valve chamber 121 and the third flow channel 1003, respectively. That is, the second valve chamber 121 is indirectly connected to the third flow channel 1003 through the fourth flow path 104.

[0205] The first flow path 101 includes a first straight section 1011 that is connected to the first valve chamber 111 and forms a straight segment; the second flow path 102 includes a second straight section 1021 that is connected to the second flow channel opening 1002 and forms a straight segment; the third flow path 103 includes a third straight section 1031 that is connected to the second valve chamber 121 and forms a straight segment; and the fourth flow path 104 includes a fourth straight section 1041 that is connected to the third flow channel opening 1003 and forms a straight segment.

[0206] The second straight portion 1021 and the fourth straight portion 1041 are parallel, which can reduce the distance between the second flow channel opening 1002 and the third flow channel opening 1003, and make the through direction of the opening of the plate heat exchanger 200 for communicating with the second flow channel opening 1002 and the third flow channel opening 1003 respectively parallel to the second straight portion 1021 and the fourth straight portion 1041, so that the second flow channel opening 1002 and the third flow channel opening 1003 can be easily connected to the plate heat exchanger 200.

[0207] In some embodiments, such as Figures 32-38 As shown, the angle between the extending direction of the first straight portion 1011 and the axial direction of the first valve member 20 is c, where 60° ≤ c ≤ 120°. Here, the axial direction of the first valve member 20 refers to the axis of the valve core of the first valve member 20. For example... Figure 38 As shown, the value of c can be 60°, 70°, 75°, 80°, 85°, 90°, 100°, 110°, 115°, 120°, etc.

[0208] In some related technologies, the heat exchange medium enters the first valve member along the axial direction. When flowing through the valve core, the heat exchange medium directly impacts the valve core from the axial direction of the first valve member, causing the valve core to move along the throttling channel and repeatedly push the valve core up, generating collision noise. However, this application, by making the angle c between the extension direction of the first straight portion 1011 and the axial direction of the first valve member 20 satisfying 60°≤c≤120°, allows the flow direction of the heat exchange medium when flowing through the first straight portion 1011 to form an angle with the axis of the first valve member 20. This reduces the flow velocity of the heat exchange medium along the axial direction of the first valve member 20, and reduces the impact force of the heat exchange medium on the valve core along the axial direction of the first valve member 20, thereby reducing the noise caused by the impact or pushing of the valve core by the heat exchange medium.

[0209] In some embodiments, such as Figures 32-38As shown, the angle between the extending direction of the third straight section 1031 and the axial direction of the second valve element 30 is d, where 60°≤d≤120°. Here, the axial direction of the second valve element 30 refers to the axis of the valve core of the second valve element 30. For example... Figure 37 As shown, the value of d can be 60°, 70°, 75°, 80°, 85°, 90°, 100°, 110°, 115°, 120°, etc.

[0210] By ensuring that d satisfies 60°≤d≤120°, the flow direction of the heat exchange medium when flowing through the third straight section 1031 forms an angle with the axis of the second valve 30. This reduces the flow velocity of the heat exchange medium along the axis of the second valve 30, and reduces the impact force of the heat exchange medium on the valve core along the axis of the second valve 30. This can reduce the noise caused by the valve core being impacted or lifted by the heat exchange medium.

[0211] In some embodiments of this utility model, such as Figures 32-37 As shown, a fifth flow path 105 for the flow of heat exchange medium is defined within the valve island 10. The second flow path 102 and the third flow path 103 are both connected to and communicate with one end of the fifth flow path 105. The other end of the fifth flow path 105 communicates with the first valve chamber 111. That is, the first valve chamber 111 is connected to the fifth flow path 105 to simultaneously connect to the second flow path 102 and the third flow path 103. Through the fifth flow path 105, one end of the first valve chamber 111 can be divided into two paths to simultaneously connect to the second flow path 102 and the third flow path 103, eliminating the need to add an opening at one end of the first valve chamber 111 to separately connect to the second flow path 102 and the third flow path 103. This simplifies the structure of the valve island 10 and improves its structural strength.

[0212] In some embodiments, such as Figures 32-37 As shown, the third flow path 103 is bent and extended. By adjusting the included angle between the bent and extended sections of the third flow path 103, the two ends of the third flow path 103 can be made perpendicular to the adjacent flow path, which helps to reduce the flow resistance at both ends of the third flow path 103 and increase the flow velocity of the heat exchange medium.

[0213] For example, in some embodiments, such as Figures 32-37As shown, the third flow path 103 includes a first segment and a second segment (i.e., the third straight section 1031) that are connected. Both the first and second segments are arranged in a straight line, and the extension directions of the first and second segments are set at an angle. The end of the first segment away from the second segment is connected to the first valve chamber 111, and the end of the second segment away from the first segment is connected to the second valve chamber 121. By adjusting the angle between the extension directions of the first and second segments, the extension direction of the first segment can be made perpendicular to the extension directions of both the fifth flow path 105 and part of the second flow path 102, and the extension direction of the second segment can be perpendicular to the axial direction of the second valve 30, which helps to reduce the flow resistance at both ends of the third flow path 103. By adjusting the angle between the bent extension segments in the third flow path 103, the manufacturing of the third flow path 103 is facilitated, and the angle between the second segment 10123 and the axial direction of the second valve 30 is easier to control, thereby reducing the refrigerant noise generated when the refrigerant flows through the second valve 30.

[0214] In some embodiments, such as Figures 32-39 As shown, the first flow path 101 extends in a bent manner. Specifically, the first flow path 101 includes a first channel and a second channel (i.e., a first straight section 1011) that are connected. Both the first channel and the second channel are arranged in a straight line, and the extension directions of the first channel and the second channel are set at an angle. The end of the first channel away from the second channel is connected to the first flow port 1001, and the end of the second channel away from the first channel is connected to the first valve chamber 111. By adjusting the angle between the bent and extended sections in the first flow path 101, the manufacturing of the first flow path 101 is facilitated, and the angle between the second channel (i.e., the first straight section 1011) and the axial direction of the first valve component 20 is easily controlled, thereby reducing the refrigerant noise generated when the refrigerant flows through the first valve component 20.

[0215] In some embodiments, such as Figures 32-39 As shown, the second flow path 102 extends in a bent manner. Specifically, the second flow path 102 includes a first part and a second part (i.e., the second straight part 1021) that are connected. Both the first part and the second part are arranged in a straight line. The extension direction of the first part and the extension direction of the second part are set at an angle. The end of the first part away from the second part is connected to the first valve chamber 111, and the end of the second part away from the first part is connected to the second flow channel opening 1002. By adjusting the angle between the bent extension segments in the second flow path 102, the manufacturing of the second flow path 102 is facilitated, and the extension direction of the first part can be made perpendicular to the extension direction of the third flow path 103, the first part and the second part are perpendicular, and the extension direction of the second part coincides with the opening direction of the second interface 2201 of the heat exchanger 200, which helps to reduce the flow resistance at both ends of the second flow path 102.

[0216] In some embodiments of this utility model, such as Figures 32-37As shown, the valve island 10 includes a first mounting portion 11, which forms a first valve cavity 111. At least a portion of the first valve member 20 is installed in the first valve cavity 111, which increases the contact area between the first valve member 20 and the inner wall of the first valve cavity 111, thereby increasing the connection strength and sealing performance between the first valve member 20 and the valve island 10. The first valve member 20 can be fixedly installed or detachably installed in the first valve cavity 111, ensuring that the first valve member 20 is securely installed to the first mounting portion 11.

[0217] In some embodiments, such as Figures 32-37 As shown, the valve island 10 includes a second mounting portion 12, which forms a second valve cavity 121. At least a portion of the second valve member 30 is installed within the second valve cavity 121, which increases the contact area between the second valve member 30 and the inner wall of the second valve cavity 121, thereby increasing the connection strength and sealing performance between the second valve member 30 and the valve island 10. The second valve member 30 can be fixedly installed or detachably installed within the second valve cavity 121, ensuring that the second valve member 30 is securely installed to the second mounting portion 12.

[0218] In some embodiments, such as Figures 32-37 As shown, the angle between the axis of the first mounting part 11 and the axis of the second mounting part 12 is e, where 0° ≤ e ≤ 60°. For example, the angle between the projections of the axes of the first mounting part 11 and the second mounting part 12 onto the plane containing the end plate is e. For example, the value of e can be 0°, 5°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, etc. In some specific embodiments, such as... Figure 37 As shown, e = a.

[0219] If the angle e between the axis of the first mounting part 11 and the axis of the second mounting part 12 is too large, it will increase the space occupied by the first mounting part 11 and the second mounting part 12, resulting in a large space occupied by the valve island 10 and a large overall volume of the throttle assembly 100, making installation more difficult. This application ensures that the angle e satisfies 0°≤e≤60°, which can appropriately reduce the space occupied by the first mounting part 11 and the second mounting part 12, making the structure of the valve island 10 more compact and the overall structure of the throttle assembly 100 more compact, thus facilitating installation.

[0220] In some embodiments, such as Figures 37-38 As shown, one end of the first valve member 20 includes a first valve port 21, a first overflow port 22, and a second valve port 23. The heat exchange medium flows from one of the first valve port 21 and the second valve port 23 through the first overflow port 22 to enter the first valve member 20 for throttling, and then flows out from the other of the first valve port 21 and the second valve port 23. The first valve port 21, the first overflow port 22, and the second valve port 23 are located at one end of the first valve member 20, making the structure of the first valve member 20 more compact. In some embodiments, the first valve member 20 is also equipped with a coil.

[0221] In some embodiments, such as Figures 37-38 As shown, one end of the second valve 30 includes a third valve port 31, a second overflow port 32, and a fourth valve port 33. The heat exchange medium flows from one of the third valve port 31 and the fourth valve port 33 through the second overflow port 32 to enter the second valve 30 for throttling, and then flows out from the other of the third valve port 31 and the fourth valve port 33. The third valve port 31, the second overflow port 32, and the fourth valve port 33 are located at one end of the second valve 30, making the structure of the second valve 30 more compact. In some embodiments, the second valve 30 is also equipped with a coil.

[0222] In some embodiments of this utility model, such as Figure 22 , Figure 24 ,and Figure 42 As shown, the first valve 20 is an electronic expansion valve or a solenoid valve. The first valve 20 includes a first coil portion 201 and a first valve core 202, with the first coil portion 201 positioned above or diagonally above the first valve core 202. Thus, by using an electronic expansion valve or a solenoid valve, the first valve 20, through the first coil portion 201 and the first valve core 202, controls the flow rate and pressure of the heat exchange medium flowing through it, achieving precise regulation of the heat exchange medium flow. For example, the first valve 20 can throttle and reduce the pressure of the heat exchange medium flowing through it, lowering its temperature and humidity.

[0223] Meanwhile, by positioning the first coil section 201 above or diagonally above the first valve core 202, the wiring terminals of the first coil section 201 can be placed in a more easily operable spatial position, effectively avoiding wiring difficulties caused by the compact structure of the first valve component 20 and improving assembly efficiency.

[0224] In some embodiments of this utility model, such as Figure 22 , Figure 24 ,and Figure 42 As shown, the second valve 30 is an electronic expansion valve or a solenoid valve. The second valve 30 includes a second coil portion 301 and a second valve core 302, with the second coil portion 301 positioned above or diagonally above the second valve core 302. Thus, by using an electronic expansion valve or a solenoid valve, the second valve 30, through the second coil portion 301 and the second valve core 302, controls the flow rate and pressure of the heat exchange medium flowing through it, achieving precise flow regulation of the heat exchange medium. For example, the second valve 30 can throttle and reduce the pressure of the heat exchange medium flowing through it, lowering its temperature and humidity.

[0225] Meanwhile, by positioning the second coil section 301 above or diagonally above the second valve core 302, the wiring terminals of the first coil section 201 can be placed in a more easily operable spatial position, effectively avoiding wiring difficulties caused by the compact structure of the second valve component 30 and improving assembly efficiency.

[0226] In some embodiments of this utility model, such as Figure 22 , Figure 24 ,and Figure 42 As shown, the first valve component 20 also includes a first support component 203. One end of the first support component 203 is connected to the first coil part 201, and the other end of the first support component 203 is connected to the valve island 10 through a first fastener 204. The first fastener 204 faces the side of the valve island 10 away from the plate heat exchanger 200.

[0227] Thus, the first coil section 201 and the valve island 10 are fixedly connected by the first support member 203, ensuring that the first coil section 201 is stably set above or diagonally above the first valve core 202, effectively preventing the first coil section 201 from shaking or shifting, improving the reliability of the first valve member 20 and the safety of the heat exchange device 1000.

[0228] In some embodiments of this utility model, such as Figure 22 , Figure 24 ,and Figure 42 As shown, the second valve 30 also includes a second support 303. One end of the second support 303 is connected to the second coil part 301, and the other end of the second support 303 is connected to the valve island 10 through a second fastener 304. The second fastener 304 faces the side of the valve island 10 away from the plate heat exchanger 200.

[0229] Thus, the second support member 303 achieves a fixed connection between the second coil section 301 and the valve island 10, ensuring that the second coil section 301 is stably positioned above or diagonally above the second valve core 302, effectively preventing the second coil section 301 from shaking or shifting, improving the reliability of the second valve 30 and the safety of the heat exchange device 1000.

[0230] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 22 , Figure 24 , Figure 42 As shown, the outer casing 41 includes a front casing and a side casing that surrounds the compressor cavity, with the first fastener 204 facing either the front casing or the side casing. This arrangement ensures that the first fastener 204 is installed facing either the front casing or the side casing, allowing it to be exposed when the corresponding front casing or side casing is removed. This facilitates wiring of the first coil section 201 and inspection and maintenance of the first valve component 20.

[0231] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 22 , Figure 24 , Figure 42 As shown, the second fastener 304 faces the front or side housing. This arrangement ensures that the second fastener 304 is installed facing the front or side housing, allowing it to be exposed when the corresponding front or side housing is removed. This facilitates wiring of the second coil section 301 and inspection and maintenance of the second valve 30.

[0232] In some embodiments of this utility model, such as Figure 32 , Figure 33 , Figure 40 and Figure 42 As shown, the first mounting portion 11 has a first opening 112 on the side facing the first interface 2202, which communicates with the first valve chamber 111. The first valve core 202 is installed into the first valve chamber 111 through the first opening 112. It can be understood that since the first interface 2202 is connected to the first connecting pipe 600, the first opening 112 on the side of the first mounting portion 11 facing the first interface 2202, which communicates with the first valve chamber 111, optimizes the spatial layout of the valve island 10 and the plate heat exchanger 200, and reduces the flow resistance of the refrigerant between the refrigerant flow path and the heat exchange flow path.

[0233] In some embodiments of this utility model, such as Figure 32 , Figure 33 , Figure 40 and Figure 42 As shown, the second mounting portion 12 has a second opening 122 on the side facing the fourth interface 2302, which communicates with the second valve chamber 121. The second valve core 302 is installed into the second valve chamber 121 through the second opening 122. It can be understood that since the fourth interface 2302 is connected to the second connecting pipe 700, the second opening 122 on the side of the second mounting portion 12 facing the fourth interface 2302, which communicates with the second valve chamber 121, optimizes the spatial layout of the valve island 10 and the plate heat exchanger 200, and reduces the flow resistance of the refrigerant between the refrigerant flow path and the heat exchange flow path.

[0234] In some embodiments of this utility model, such as Figure 32 , Figure 33 and Figure 42 As shown, the first opening 112 and the second opening 122 face the same side, and the first interface 2202 and the fourth interface 2302 are located between the axis of the first opening 112 and the axis of the second opening 122.

[0235] Therefore, this arrangement reduces interference between the second connecting pipe 700 connected to the fourth interface 2302 and the first connecting pipe 600 connected to the first interface 2202 and the first valve 20, as well as reduces interference between the second connecting pipe 700 connected to the fourth interface 2302 and the first connecting pipe 600 connected to the first interface 2202 and the second valve 30, further optimizing the spatial layout of the valve island 10 and the plate heat exchanger 200. Simultaneously, it facilitates the installation of the first valve core 202 from the direction of the first opening 112 into the first valve cavity 111, and facilitates the installation of the second valve core 302 from the direction of the second opening 122 into the second valve cavity 121, reducing assembly difficulty and improving assembly efficiency.

[0236] In some embodiments, such as Figures 32-39 As shown, both the first valve 20 and the second valve 30 are used to control the flow rate and pressure of the heat exchange medium flowing through them, so as to achieve precise flow regulation of the heat exchange medium. For example, both the first valve 20 and the second valve 30 can throttle and reduce the pressure of the heat exchange medium flowing through them, thereby reducing the temperature and pressure of the heat exchange medium. The first valve 20 is an electronic expansion valve, which includes a first valve shell and a first valve core 202. The first valve shell forms a first throttling channel communicating with the first valve chamber 111, and at least a portion of the first valve core 202 is movably disposed within the first throttling channel. The second valve 30 is an electronic expansion valve, which includes a second valve shell and a second valve core 302. The second valve shell forms a second throttling channel communicating with the second valve chamber 121, and at least a portion of the second valve core 302 is movably disposed within the second throttling channel. The first valve 20 and the second valve 30 can also be thermostatic expansion valves or other types of throttling devices.

[0237] By installing the first valve 20 and the second valve 30 on the valve island 10, the valve island 10, the first valve 20 and the second valve 30 are integrated, reducing the space occupied by the valve island 10, the first valve 20 and the second valve 30, improving the structural compactness of the throttle assembly 100, and realizing the miniaturization of the throttle assembly 100 and the plate heat exchanger 200 as a whole.

[0238] The first valve 20 and the second valve 30 can both throttle and reduce the pressure of the heat exchange medium flowing through them. By adjusting the opening degree of the first valve 20 and the second valve 30, the degree of throttling and pressure reduction of the heat exchange medium can be adjusted, thereby achieving the regulation of the pressure and temperature of the heat exchange medium within the valve island 10.

[0239] The throttling device assembly 100 can define multiple flow paths for the heat exchange medium, both ends of which are connected to the outside of the throttling device assembly 100. The heat exchange medium in each flow path flows through at least one of the first valve 20 and the second valve 30. By adjusting the first flow port 1001, the second flow port 1002, and the third flow port 1003 as either inlets or outlets, the flow path of the heat exchange medium in the throttling device assembly 100 can be adjusted. The flow paths of the throttling device assembly 100 are diverse and flexibly adjustable. Combined with the adjustment of the opening degree of the first valve 20 and the second valve 30, the throttling function of the throttling device assembly 100 is made more diverse.

[0240] According to some embodiments of this utility model, refer to Figure 32 and Figure 42 The angle between the axis of the first valve element 20 and the length direction of the plate heat exchanger 200 is α1, where 0°≤α1≤45°. For example, the axis of the first valve element 20 can be the axis of the valve core of the first valve element 20, and the axis of the first valve element 20 is L1. The value of α1 can be 0°, 5°, 10°, 30°, or 45°, etc. By ensuring that the angle α1 between the axis of the first valve element 20 and the length direction of the plate heat exchanger 200 satisfies 0°≤α1≤45°, the overall structure of the throttling device assembly 100 can be made more compact, reducing the space occupied by the throttling device assembly 100.

[0241] According to some embodiments of this utility model, refer to Figure 32 and Figure 42 The angle between the axis of the second valve 30 and the length direction of the plate heat exchanger 200 is α2, where 0°≤α2≤45°. For example, the axis of the second valve 30 can be the axis of the valve core of the second valve 30, and the axis of the second valve 30 is L2. The value of α2 can be 0°, 5°, 10°, 30°, or 45°, etc. By ensuring that the angle α2 between the axis of the second valve 30 and the length direction of the plate heat exchanger 200 satisfies 0°≤α2≤45°, the overall structure of the throttle assembly 100 can be made more compact, reducing the space occupied by the throttle assembly 100.

[0242] For example, the angle α1 between the axis of the first valve 20 and the length direction of the plate heat exchanger 200 satisfies 0°≤α1≤45°, and the angle α2 between the axis of the second valve 30 and the length direction of the plate heat exchanger 200 satisfies 0°≤α2≤45°.

[0243] According to some embodiments of this utility model, refer to Figure 32 and Figure 420°≤α1≤30°. For example, the value of α1 can be 0°, 10°, 20° or 30°, etc. By ensuring that the angle α1 between the axis of the first valve 20 and the length direction of the plate heat exchanger 200 satisfies α1≤30°, the total length of the throttle assembly 100 in the width direction of the plate heat exchanger 200 can be appropriately reduced, avoiding the throttle assembly 100 occupying too much space and being difficult to install due to the excessive tilt angle of the axis of the first valve 20 relative to the length direction of the plate heat exchanger 200.

[0244] According to some embodiments of this utility model, refer to Figure 32 and Figure 42 The angle α2 between the axis of the second valve 30 and the length direction of the plate heat exchanger 200 is 5°≤α2≤30°. For example, the value of α2 can be 5°, 10°, 20° or 30°. By ensuring that the angle α2 between the axis of the second valve 30 and the length direction of the plate heat exchanger 200 is 5°≤α2, the axis of the second valve 30 can be tilted relative to the length direction of the plate heat exchanger 200, making the internal structure of the throttle assembly 100 more compact. By ensuring that the angle α2 between the axis of the second valve 30 and the length direction of the plate heat exchanger 200 is α2<60°, the total length of the throttle assembly 100 in the width direction of the plate heat exchanger 200 can be appropriately reduced, avoiding the throttle assembly 100 from occupying too much space and being difficult to install due to the excessive tilt angle of the axis of the second valve 30 relative to the length direction of the plate heat exchanger 200.

[0245] According to some embodiments of this utility model, refer to Figure 32 and Figure 42 The absolute value of the difference between α1 and α2 is less than 30°. When the absolute value of the difference between α1 and α2 is too large, the angle between the axis of the first valve 20 and the axis of the second valve 30 is too large. This will cause the maximum length of the first valve 20 and the second valve 30 in the width direction of the plate heat exchanger 200 to be too large, increasing the space occupied by the throttle assembly 100 and making the installation of the throttle assembly 100 more difficult. By making the absolute value of the difference between α1 and α2 less than 30°, the total length of the throttle assembly 100 in the width direction of the plate heat exchanger 200 can be appropriately reduced, making the internal structure of the throttle assembly 100 more compact and avoiding the excessively large relative opening angle between the first valve 20 and the second valve 30, which would lead to an excessively large total length of the plate heat exchanger 200 in the width direction and make installation difficult.

[0246] According to some embodiments of this utility model, refer to Figure 32 and Figure 42The angle between the axis of the first valve element 20 and the axis of the second valve element 30 is θ, where 0° < θ < 180°. For example, the value of θ can be 5°, 30°, 45°, 60°, 90°, 120°, 150°, 160°, 170°, etc. By ensuring that the angle θ between the axis of the first valve element 20 and the axis of the second valve element 30 satisfies 0° < θ < 180°, the axes of the first valve element 20 and the second valve element 30 are not parallel, making the internal structure of the throttle assembly 100 more compact.

[0247] According to some embodiments of this utility model, refer to Figure 32 and Figure 42 The angle θ between the axis of the first valve 20 and the axis of the second valve 30 satisfies 5° < θ. For example, the value of θ can be 6°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70°, 80°, etc. By ensuring that the angle θ between the axis of the first valve 20 and the axis of the second valve 30 is 5° < θ, the axes of the first valve 20 and the second valve 30 are not parallel, making the internal structure of the throttle assembly 100 more compact. When the absolute value of the difference between the angle θ between the axes of the first valve 20 and the second valve 30 is too large, the angle between the axes of the first valve 20 and the second valve 30 will be too large, resulting in an excessively large maximum length of the first valve 20 and the second valve 30 in the width direction of the plate heat exchanger 200. This increases the space occupied by the throttle assembly 100, making the installation of the throttle assembly 100 more difficult. By ensuring that the angle θ between the axis of the first valve 20 and the axis of the second valve 30 satisfies θ < 90°, the total length of the throttle assembly 100 in the width direction of the plate heat exchanger 200 can be appropriately reduced, making the internal structure of the throttle assembly 100 more compact and avoiding excessive relative opening angle between the first valve 20 and the second valve 30, which would lead to an excessively large total length in the width direction of the plate heat exchanger 200 and installation difficulties.

[0248] According to some embodiments of this utility model, refer to Figure 32 and Figure 42The plate heat exchanger 200 includes a heat exchange body 210, which includes multiple stacked heat exchange plates and a first plate 240 and a second plate 250 disposed on both sides of the heat exchange plates. The first plate 240 includes a planar portion 260, on which a first valve 20 and a second valve 30 are both disposed. The angle between the projections of the axis of the first valve 20 and the axis of the second valve 30 onto the plane containing the planar portion 260 is α, where 0°≤α≤60°. For example, the value of α can be 5°, 10°, 20°, 30°, 40°, 45°, 50°, 59°, etc. The angle α between the projections of the axes of the first valve 20 and the second valve 30 onto the plane of the planar portion 260 is too large. This excessive angle between the axes of the first valve 20 and the second valve 30 results in an excessively large maximum length of the first valve 20 and the second valve 30 in the width direction of the plate heat exchanger 200, increasing the space occupied by the throttle assembly 100 and making its installation difficult. By ensuring that the angle α between the projections of the axes of the first valve 20 and the second valve 30 onto the plane of the planar portion 260 satisfies 0°≤a≤60°, the total length of the throttle assembly 100 in the width direction of the plate heat exchanger 200 can be appropriately reduced. This makes the internal structure of the throttle assembly 100 more compact and avoids the excessively large relative opening angle between the first valve 20 and the second valve 30, which would otherwise lead to an excessively large total length of the throttle assembly 100 in the width direction of the plate heat exchanger 200 and make installation difficult.

[0249] According to some embodiments of this utility model, the plate heat exchanger 200 is arranged vertically or inclined. The first interface 2202 and the fourth interface 2302 are located above or obliquely above the second interface 2201 and the third interface 2301. The plate heat exchanger 200 includes a heat exchange body 210, which includes multiple heat exchange plates stacked together and a first plate 240 and a second plate 250 disposed on both sides of the heat exchange plates. The first plate 240 includes a flat portion 260, and a valve island 10 is disposed on the flat portion 260. The angle between the axis of the first valve 20 and the plane containing the flat portion 260 is f, where -30°≤b≤30°. For example, the value of f can be -30°, -20°, -10°, 0°, 10°, 15°, 20°, 30°, etc. By arranging both the first valve element 20 and the second valve element 30 on the flat portion 260, and ensuring that the angle f between the axis of the first valve element 20 and the plane containing the flat portion 260 satisfies -30°≤f≤30°, the vibration wear of the valve core of the first valve element 20 can be reduced.

[0250] According to some embodiments of this utility model, the plate heat exchanger 200 is arranged vertically or inclined. The first interface 2202 and the fourth interface 2302 are located above or obliquely above the second interface 2201 and the third interface 2301. The plate heat exchanger 200 includes a heat exchange body 210, which includes multiple heat exchange plates stacked together and a first plate 240 and a second plate 250 disposed on both sides of the heat exchange plates. The first plate 240 includes a flat portion 260, and the valve island 10 is disposed on the flat portion 260. The angle between the axis of the second valve 30 and the plane containing the flat portion 260 is g, where -30°≤g≤30°. For example, the value of g can be -30°, -20°, -10°, 0°, 10°, 15°, 20°, 30°, etc. By ensuring that the angle g between the axis of the second valve 30 and the plane containing the planar portion 260 satisfies -30°≤g≤30°, the vibration wear of the valve core of the second valve 30 can be reduced.

[0251] According to some embodiments of this utility model, refer to Figure 32 and Figure 42 The line connecting the center of the first interface 2202 and the center of the second interface 2201 is the first connecting line 270, and the line connecting the center of the third interface 2301 and the center of the fourth interface 2302 is the second connecting line 280. The angle between the axis of the first valve 20 and the first connecting line 270 is β1, and the angle between the axis of the second valve 30 and the second connecting line 280 is β2, where 0°≤β1<45° and / or 0°≤β2≤45°. For example, the value of β1 can be 0°, 10°, 30°, or 45°, etc.; the value of β2 can be 0°, 10°, 30°, or 45°, etc. By ensuring that the angle β1 between the axis of the first valve member 20 and the first connecting line 270 satisfies 0°≤β1<45°, and / or that the angle β2 between the axis of the second valve member 30 and the second connecting line 280 satisfies 0°≤β2≤45°, the overall structure of the throttle assembly 100 can be made more compact, reducing the space occupied by the throttle assembly 100.

[0252] According to some embodiments of this utility model, refer to Figure 32 and Figure 42 0°≤β1≤30°. For example, the value of β1 can be 0°, 10°, 20° or 30°, etc. By ensuring that the included angle β1 between the axis of the first valve 20 and the first connecting line 270 satisfies β1<60°, the total length of the throttle assembly 100 in the width direction of the plate heat exchanger 200 can be appropriately reduced, avoiding the situation where the axis of the first valve 20 is tilted too much relative to the first connecting line 270, resulting in the throttle assembly 100 occupying too much space and causing installation difficulties.

[0253] According to some embodiments of this utility model, refer to Figure 32 and Figure 420°≤β2≤30°. For example, the value of β2 can be 0°, 10°, 20° or 30°, etc. By ensuring that the included angle β2 between the axis of the second valve 30 and the second connecting line 280 satisfies β2<60°, the total length of the throttle assembly 100 in the width direction of the plate heat exchanger 200 can be appropriately reduced, avoiding excessive tilt angle of the axis of the second valve 30 relative to the second connecting line 280, which would cause the throttle assembly 100 to occupy too much space and be difficult to install.

[0254] According to some embodiments of this utility model, refer to Figure 32 and Figure 42 The absolute value of the difference between β1 and β2 is less than 30°. When the absolute value of the difference between β1 and β2 is too large, the angle between the axis of the first valve 20 and the axis of the second valve 30 is too large. This will cause the maximum length of the first valve 20 and the second valve 30 in the width direction of the plate heat exchanger 200 to be too large, increasing the space occupied by the throttle assembly 100 and making the installation of the throttle assembly 100 more difficult. By making the absolute value of the difference between β1 and β2 less than 30°, the total length of the throttle assembly 100 in the width direction of the plate heat exchanger 200 can be appropriately reduced, making the internal structure of the throttle assembly 100 more compact and avoiding the excessively large relative opening angle between the first valve 20 and the second valve 30, which would lead to an excessively large total length of the plate heat exchanger 200 in the width direction and make installation difficult.

[0255] In some embodiments of this utility model, such as Figures 15-18 and Figure 22 As shown, the plate heat exchanger 200 includes a heat exchange body 210, which includes multiple heat exchange plates stacked together and a first plate 240 and a second plate 250 disposed on both sides of the heat exchange plates. The valve island 10 is disposed on the first plate 240, and the second plate 250 is provided with a mounting part. The mounting part is fixedly connected to the fixing component 500 or is an integral part.

[0256] Understandably, the plate heat exchanger 200 is connected to the fixed assembly 500 via the mounting part on the second plate 250, thereby connecting the plate heat exchanger 200 to the fixed assembly 500. This, in turn, allows the heat exchange device 1000 to be fixed to the casing 3000 via the fixed assembly 500, improving overall compactness. Simultaneously, the fixed connection between the mounting part and the fixed assembly 500 facilitates the assembly and disassembly of the fixed assembly 500 and the heat exchange device 1000, thus simplifying maintenance of the heat exchange device 1000. Furthermore, the mounting part and valve island are positioned on opposite sides of the heat exchange plate, reducing interference between them and facilitating assembly.

[0257] In some embodiments of this utility model, such as Figures 1-18 As shown, the second plate 250 is installed vertically or at an angle (which can be understood as the second plate 250 extending along the height direction of the outdoor unit 10000, that is...). Figure 1(Extending vertically as shown in the figure), the first port 2202 and the fourth port 2302 of the plate heat exchanger 200 are located above or diagonally above the second port 2201 and the third port 2301. The angle between the axial direction of the valve and / or the movement direction of the valve core and the plane where the first plate 240 is located is A1, 0°≤A1≤30°.

[0258] It is understandable that when the second plate 250 is set vertically or at an angle, the first interface 2202 and the fourth interface 2302 are located above or diagonally above the second interface 2201 and the third interface 2301, so that the first interface 2202 and the fourth interface 2302 are arranged in the vertical direction, and the second interface 2201 and the third interface 2301 are arranged in the vertical direction, the spatial layout of the plate heat exchanger 200 is further optimized, and the flow of refrigerant in the heat exchange path is facilitated.

[0259] Meanwhile, by making an angle A1 between the axial direction of the valve and / or the movement direction of the valve core and the plane where the first plate 240 is located, where 0°≤A1≤30°, the valve core can achieve at least one of opening, closing, flow regulation, and throttling opening regulation of the refrigerant flow path. At the same time, it makes the force distribution (the supporting force against the gravity of the valve core) on the same or adjacent circumferential surfaces of the valve core more uniform. During operation, the wear on the same or adjacent circumferential surfaces of the valve core is more uniform, avoiding excessive local wear of the valve core, improving the operational reliability and life of the valve, reducing noise, and thus improving the reliability of the heat exchange device 1000.

[0260] It should be noted that A1 can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, or 45°. Preferably, A1 is 0°-30°, and more preferably, A1 is 0°-15°.

[0261] In some embodiments of this utility model, such as Figures 1-18 As shown, the second plate 250 is horizontally positioned, and the valve island 10 is located above the second plate 250. The angle between the axial direction of the valve and / or the movement direction of the valve core and the plane where the second plate 250 is located is A2, where 60°≤A2≤90°. Therefore, based on the space within the outdoor unit 10000, the plate heat exchanger 200 can be horizontally positioned to ensure the second plate 250 is also horizontally positioned. Furthermore, by positioning the valve island 10 above the plate heat exchanger 200, the refrigerant can flow smoothly between the refrigerant channel of the valve island 10 and the heat exchange channel of the plate heat exchanger 200, further optimizing the spatial layout of the plate heat exchanger 200.

[0262] Meanwhile, by making an angle A2 between the axial direction of the valve and / or the movement direction of the valve core and the plane where the second plate 250 is located, where 60°≤A2≤90°, the valve core can achieve at least one of the following: opening, closing, flow regulation, and throttling opening regulation of the refrigerant flow path. At the same time, it makes the force distribution (the supporting force against the gravity of the valve core) on the same or adjacent circumferential surfaces of the valve core more uniform. During operation, the wear on the same or adjacent circumferential surfaces of the valve core is more uniform, avoiding excessive local wear of the valve core, improving the operational reliability and life of the valve, reducing noise, and thus improving the reliability of the heat exchange device 1000.

[0263] In some embodiments of this utility model, Figures 15-18 The plate heat exchanger 200 includes a heat exchange body 210, which includes multiple heat exchange plates stacked together and a first plate 240 and a second plate 250 disposed on both sides of the heat exchange plates. The valve island 10 is disposed on the first plate 240, which is provided with a mounting part. The mounting part is fixedly connected to the fixing component 500 or is an integral structure.

[0264] Therefore, the plate heat exchanger 200 is fixedly connected to the fixing component 500 via the mounting part provided on the second plate 250, thereby connecting the plate heat exchanger 200 to the fixing component 500. This allows the heat exchange device 1000 to be fixed to the casing 3000 via the fixing component 500, improving overall compactness. Simultaneously, the fixed connection between the mounting part and the fixing component 500 facilitates the assembly and disassembly of the fixing component 500 and the heat exchange device 1000, thus simplifying maintenance of the heat exchange device 1000. Furthermore, the fact that the mounting part and the valve island 10 are located on the same side of the heat exchange plate further enhances compactness and achieves miniaturization.

[0265] In some embodiments of this utility model, the first plate 240 is arranged vertically or inclined, and the first interface 2202 and the fourth interface 2302 of the plate heat exchanger 200 are located above or obliquely above the second interface 2201 and the third interface 2301. The angle between the axial direction of the valve and / or the movement direction of the valve core and the plane where the first plate 240 is located is B1, where 0°≤B1≤30°.

[0266] It is understandable that when the first plate 240 is set vertically or at an angle, the first interface 2202 and the fourth interface 2302 are located above or diagonally above the second interface 2201 and the third interface 2301, so that the first interface 2202 and the fourth interface 2302 are arranged in the vertical direction, and the second interface 2201 and the third interface 2301 are arranged in the vertical direction, the spatial layout of the plate heat exchanger 200 is further optimized, and the flow of refrigerant in the heat exchange path is facilitated.

[0267] Meanwhile, by making an angle B1 between the axial direction of the valve and / or the movement direction of the valve core and the plane where the first plate 240 is located, where 0°≤B1≤30°, the valve core can achieve at least one of opening, closing, flow regulation, and throttling opening regulation of the refrigerant flow path. At the same time, it makes the force distribution (the supporting force against the gravity of the valve core) on the same or adjacent circumferential surfaces of the valve core more uniform. During operation, the wear on the same or adjacent circumferential surfaces of the valve core is more uniform, avoiding excessive local wear of the valve core, improving the operational reliability and life of the valve, reducing noise, and thus improving the reliability of the heat exchange device 1000.

[0268] It should be noted that B1 can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, or 45°. Preferably, B1 is 0°-30°, and more preferably, B1 is 0°-15°.

[0269] In some embodiments of this utility model, such as Figures 13-16 As shown, the second plate 250 is horizontally positioned, and the valve island 10 is located above the second plate 250. The angle between the axial direction of the valve and / or the movement direction of the valve core and the plane where the second plate is located is B2, where 60°≤B2≤90°.

[0270] Therefore, based on the space inside the outdoor unit 10000 of the air conditioner, the plate heat exchanger 200 can be set horizontally so that the second plate 250 can be set horizontally, and the valve island 10 can be located above the plate heat exchanger 200 so that the valve island 10 is located above the second plate 250, ensuring that the refrigerant flows smoothly between the refrigerant flow channel of the valve island 10 and the heat exchange flow channel of the plate heat exchanger 200, further optimizing the spatial layout of the plate heat exchanger 200.

[0271] Meanwhile, by making an angle B2 between the axial direction of the valve and / or the movement direction of the valve core and the plane where the second plate 250 is located, where 60°≤B2≤90°, the valve core can achieve at least one of the following: opening, closing, flow regulation, and throttling opening regulation of the refrigerant flow path. At the same time, it makes the force distribution (the supporting force against the gravity of the valve core) on the same or adjacent circumferential surfaces of the valve core more uniform. During operation, the wear on the same or adjacent circumferential surfaces of the valve core is more uniform, avoiding excessive local wear of the valve core, improving the operational reliability and life of the valve, reducing noise, and thus improving the reliability of the heat exchange device 1000.

[0272] In some embodiments of this utility model, such as Figures 13-16As shown, the fixed surface 401, plate heat exchanger 200, and valve island 10 are arranged vertically along the outdoor unit 10000, with valve island 10 located above plate heat exchanger 200. It is understood that the valve island fasteners 900 and fixing components 500 are disassembled and installed vertically. Since valve island 10 is located above plate heat exchanger 200 and fixed surface 401 is located below plate heat exchanger 200, when valve island 10 needs to be disassembled, only the top plate of the casing 4000 needs to be removed to disassemble and install valve island fasteners 900 and remove / place valve island 10 from the top side in a straight vertical direction. When the entire heat exchange device 1000 needs to be disassembled and installed, the fixing components 500 are removed vertically, and the heat exchange device 1000 is pulled out / pushed in vertically, without needing to go around to the front, back, left, or right sides of the unit, reducing interference with air ducts, pipes, and wiring harnesses.

[0273] Meanwhile, the fixed surface 401 is located below the plate heat exchanger 200 so that the fixed component 500 can provide support and limit from below, achieving stable positioning and good vibration resistance. The valve island 10 is located above the plate heat exchanger 200, with the operating surface facing the top plate, which facilitates quick access and maintenance from one side, further improving disassembly and assembly efficiency.

[0274] In some embodiments of this utility model, such as Figures 13-16 As shown, the minimum distance between the heat exchange device 1000 and the right side plate 414 of the casing 4000 is less than or equal to 150 mm.

[0275] It is understandable that, since the fixed surface 401, plate heat exchanger 200 and valve island 10 are arranged along the vertical direction of the outdoor unit 10000, and the valve island 10 is located above the plate heat exchanger 200, the valve island fastener 900 and the fixing component 500 are disassembled and installed in the vertical direction. By limiting the minimum distance between the heat device 1000 and the right side plate 414 of the casing 4000 to less than or equal to 150mm, the size of the outdoor unit 10000 in the left and right direction is effectively reduced, the volume of the outdoor unit 10000 is reduced, and the valve island fastener 900 and the fixing component 500 can be disassembled and installed from the top side in the vertical direction without affecting the disassembly of the top plate of the casing 40000.

[0276] In some embodiments of this utility model, such as Figures 13-16 As shown, the projection of the valve island fastener 900 toward the right side plate 414 is not obstructed by other components of the air conditioner outdoor unit 10000.

[0277] Understandably, since the fixed surface 401, plate heat exchanger 200, and valve island 10 are arranged vertically along the outdoor unit 10000, with valve island 10 located above plate heat exchanger 200, the projection of valve island fastener 900 onto the right side plate 414 is limited to prevent obstruction by other components of the outdoor unit 10000. This allows personnel to directly observe the heat exchange device 1000 after disassembling the right side plate 414. Valve island fastener 900 is located within a clearly visible projection area, without obstruction or interference from ducts, pipes, wiring harnesses, brackets, or other components. Therefore, while the vertical direction of valve island fastener 900 and fixing component 500 remains unchanged, this arrangement facilitates lateral assembly verification and status checks (such as torque marking, confirmation of valve island fastener 900 and fixing component 500's position, and inspection photography), and provides lateral emergency fine-tuning space when needed, further improving maintenance reliability.

[0278] In some embodiments of this utility model, such as Figures 1-16 As shown, the disassembly and assembly direction of the heat exchanger 1000 is the same as that of the valve island 10. Therefore, by aligning the disassembly and assembly directions of the heat exchanger 1000 and the valve island 10 to the same side, the disassembly and assembly operations of both the heat exchanger 1000 and the valve island 10 can be completed in a straight, forward-backward motion on the same side. This avoids having to go around to the opposite side or flip parts, ensuring a single, unobstructed work path, reducing the risk of interference and misassembly caused by multi-directional operations, and improving disassembly and assembly efficiency.

[0279] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the heat exchanger 1000 has a disassembly and assembly space between the side facing the valve island fastener 900 in the disassembly direction and the housing 4000. This space is used to disassemble the valve island fastener 900 and / or the fixing component 500. Therefore, by reserving this disassembly and assembly space on the side facing the valve island fastener 900 in the disassembly and assembly direction, the valve island fastener 900 and the fixing component 500 are directly visible after the corresponding panel is removed, without any obstruction or interference from other components inside the outdoor unit 10000. Disassembly tools can directly disassemble the valve island fastener 900 and / or the fixing component 500 along the disassembly and assembly direction, further improving disassembly and maintenance efficiency.

[0280] For example, such as Figures 1-3 As shown, the fixed surface 401, plate heat exchanger 200, and valve island 10 are arranged along the front-to-back direction. The fixed surface 401 is formed on the rear side plate 413 of the housing 4000, and there is a disassembly space between the heat exchange device 1000 and the front panel 412. Therefore, when it is necessary to disassemble the valve island 10 and the heat exchange device 1000 as a whole, only the front panel 412 needs to be removed, and the valve island fasteners 900 and / or fixing components 500 can be removed from the front.

[0281] For example, such as Figure 1 , Figure 2 , Figure 6 and Figure 10 As shown, when the fixed surface 401, plate heat exchanger 200, and valve island 10 are aligned with the left-right direction of the outdoor unit 10000, the casing 4000 includes a partition 42, which divides the installation space 411 into a fan chamber 4112 and a compressor chamber 4111. The heat exchanger 1000 is installed in the compressor chamber 4111. The fixed surface 401 is formed on the partition 42 or the fixing component 500 of the casing 4000. There is a disassembly space between the heat exchanger 1000 and the right side plate 414. Therefore, when it is necessary to disassemble the valve island 10 and the heat exchanger 1000 as a whole, only the right side plate 414 needs to be removed, and the valve island fastener 900 and / or fixing component 500 can be removed from the right side.

[0282] For example, such as Figure 1 , Figure 2 and Figure 13 As shown, the fixed surface 401, plate heat exchanger 200, and valve island 10 are arranged vertically. The fixed surface 401 is formed on the fixed assembly 500, the valve island 10 is located above the plate heat exchanger 200, and the fixed surface 401 is located below the plate heat exchanger 200. There is a disassembly space between the heat exchange device 1000 and the top plate. Therefore, when it is necessary to disassemble the valve island 10 and the heat exchange device 1000 as a whole, only the top plate needs to be removed, and the valve island fastener 900 and / or the fixed assembly 500 can be removed from the top.

[0283] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the outdoor unit of the air conditioner also includes a compressor 2100, a four-way valve 2200, a gas-liquid separator 5000, an outdoor heat exchanger 2300, and connecting pipes. The connecting pipes are used to connect the heat exchanger 1000, the compressor 2100, the four-way valve, the gas-liquid separator 5000, and the outdoor heat exchanger 2300. The compressor 2100, the four-way valve 2200, the gas-liquid separator 5000, the outdoor heat exchanger 2300, and the connecting pipes (except for those directly connected to the heat exchanger 1000) together form a clearance space. The heat exchanger 1000 is installed in the clearance space.

[0284] Therefore, after removing a portion of the casing (such as the top plate or right side plate 414), the valve island fasteners 900 and the fixing components 500 are directly visible and accessible, without obstructing or interfering with the compressor 2100, four-way valve 2200, gas-liquid separator 5000, outdoor heat exchanger 2300 and their connecting pipes. This allows the disassembly and assembly tools to move straight in and out along the disassembly and assembly direction to complete the operation, further facilitating disassembly and assembly, reducing the difficulty of disassembly and assembly, and improving the efficiency of disassembly and assembly.

[0285] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the valve island fastener 900 does not have any connecting pipes other than the connecting pipes directly connected to the heat exchange device 1000 on one side along the disassembly and assembly direction of the valve island fastener 900. This allows the valve island fastener 900 and the fixing component 500 to be directly visible and accessible after the partial casing (e.g., the top plate or the right side plate 414) is removed. Tools can be moved in and out in the disassembly and assembly direction for alignment and operation without obstruction or interference with the compressor 2100, the four-way valve 2200, the gas-liquid separator 5000, the outdoor heat exchanger 2300 and their piping. This reduces posture changes and tool switching during disassembly and assembly, and improves work efficiency and consistency.

[0286] Alternatively, the connecting pipes on the side of the valve island fastener 900 along the disassembly / assembly direction of the valve island fastener 900, excluding the connecting pipes directly connected to the heat exchange device 1000, form a clearance space to avoid removing at least one of the valve island fastener 900, the heat exchange device 1000, and the fixing component 500 from the air conditioning outdoor unit 10000. This ensures that after removing a portion of the casing (e.g., the top plate or the right side plate 414), the valve island fastener 900 and the fixing component 500 remain within a wide field of view and working window. Tools can be aligned and tightened / loosened in one go within the clearance space, reducing the probability of collisions with pipes, wiring harnesses, and air ducts, and reducing mid-process turning and flipping actions, thus improving assembly consistency and torque controllability.

[0287] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a plane located on one side of the valve island fastener 900 along the disassembly / assembly direction and perpendicular to the disassembly / assembly direction is defined as the reference plane. The projection of at least one of the valve island fastener 900, the heat exchange device 1000, and the fixing assembly 500 toward the reference plane is not obstructed by connecting pipes other than those directly connected to the heat exchange device 1000.

[0288] Therefore, after removing a portion of the casing (such as the top plate or right side plate 414), this setup allows for a wide field of view and working window in the reference plane direction: on the one hand, it facilitates quality control actions such as applying tightening torque, confirming the position of valve island fasteners 900 and fixing components 500, checking markings, and taking photos for record-keeping; on the other hand, it ensures that the trajectory and clearance space of the components remain consistent during the extraction / insertion process, avoiding collisions with adjacent components, further facilitating disassembly and assembly, reducing disassembly and assembly difficulty, and improving disassembly and assembly efficiency.

[0289] It should be noted that the above-mentioned connecting pipes include, but are not limited to, the first connecting pipe 600, the second connecting pipe 700, and the third connecting pipe 800.

[0290] In some embodiments of this utility model, such as Figures 17-20 As shown, the valve island 10 is provided with a first through hole 1101, and the plate heat exchanger 200 includes a mounting plate 290. The mounting plate 290 is provided with a second through hole 2902. The first through hole 1101 and the second through hole 2902 are arranged along the disassembly and assembly direction of the valve island fastener 900. The valve island fastener 900 passes through the first through hole 1101 and the second through hole 2902.

[0291] Therefore, by fastening the valve island 10 through the first through hole 1101 and the mounting plate 290 through the valve island fastener 900, the valve island 10 and the heat exchanger can be securely connected, improving the connection strength between the valve island 10 and the plate heat exchanger 200, and facilitating operation. Simultaneously, the arrangement of the first through hole 1101 and the second through hole 2902 along the disassembly and assembly direction of the valve island fastener 900 further ensures the disassembly and assembly direction of the valve island fastener 900, improving assembly efficiency.

[0292] The valve island fastener 900 may include one or more of bolts, screws, studs, nuts, washers, etc. For example, in some specific embodiments, the valve island fastener 900 includes a bolt, a nut, and two washers. The bolt passes through the first through hole 1101, the second through hole 2902, and the two washers in sequence from top to bottom, and is then threadedly fastened to the nut on the lower side of the mounting plate 290, resulting in high connection strength and convenient operation.

[0293] Furthermore, the valve island 10 includes a valve island 10 bracket with a first through hole 1101. The valve island fastener 900 connects the valve island 10 bracket and the mounting plate 290, thereby achieving the integration of the valve island 10 and the plate heat exchanger 200.

[0294] In some embodiments of this utility model, such as Figures 17-20 As shown, the plate heat exchanger 200 also includes a heat exchange body 210. Along the disassembly / assembly direction of the valve island fastener 900, the heat exchange body 210 is located on the side of the mounting plate 290 opposite to the valve island 10. In the width direction of the heat exchange body 210, the mounting plate 290 has a protrusion 2901 extending beyond the heat exchange body 210, and a second through hole 2902 is formed in the protrusion 2901. Therefore, the formation of the second through hole 2902 in the protrusion 2901 reduces the likelihood of interference between the valve island fastener 900 and the heat exchange body 210 during installation along the disassembly / assembly direction into the first through hole 1101 and the second through hole 2902. This makes the installation of the valve island fastener 900 more convenient and improves assembly efficiency.

[0295] Furthermore, the heat exchange body 210 includes multiple heat exchange plates stacked together and a first plate 240 and a second plate 250 disposed on both sides of the heat exchange plates. The mounting plate 290 is fixedly connected to the first plate 240 or is an integrally formed part.

[0296] In some embodiments of this utility model, such as Figures 17-20 As shown, there are two protrusions 2901, which are located on both sides of the width direction of the heat exchange body 210. Each of the two protrusions 2901 is provided with a second through hole 2902, and there are multiple first through holes 1101 that correspond one-to-one with the second through holes 2902.

[0297] Therefore, this arrangement makes it less likely for each valve island fastener 900 to interfere with the heat exchange body 210 during the process of passing through the corresponding first through hole 1101 and second through hole 2902 in the disassembly and assembly direction. This makes the installation of the valve island fastener 900 more convenient, and the connection strength is further improved by the two protrusions 2901 located on both sides of the width direction of the heat exchange body 210.

[0298] It should be noted that, Figure 20 The illustration shows two second through holes 2902 on each protrusion 2901 for illustrative purposes. However, after reading the following technical solution, those skilled in the art will obviously understand that applying this solution to a technical solution with one, three, or more second through holes 2902 would also fall within the protection scope of this utility model.

[0299] The following describes an embodiment of the air conditioner 2000 of this utility model.

[0300] An air conditioner 2000 according to an embodiment of the present utility model includes an outdoor unit 10000.

[0301] According to an embodiment of the present invention, an air conditioner 2000 includes an outdoor unit 10000. A casing 4000 forms an installation space 411. A heat exchange device 1000 is installed within the installation space 411 and includes a plate heat exchanger 200, a throttling device assembly 100, and a valve island fastener 900. The throttling device assembly 100 includes a valve island 10. The valve island 10 is detachably installed on the plate heat exchanger 200 using the valve island fastener 900, thereby integrating the plate heat exchanger 200 and the throttling device assembly 100. This improves the structural compactness between the plate heat exchanger 200 and the throttling device assembly 100, reduces the installation space 411 occupied by the heat exchange device 1000, and fixes the heat exchange device 1000 within the installation space 411 using a fixing component 500, ensuring stable support for the heat exchange device 1000 within the installation space 411 and improving the overall operational reliability of the air conditioner 2000. Meanwhile, by having the valve island fastener 900 and the fixing component 500 oriented to the same side for disassembly and assembly, disassembly and assembly can be performed on the same side. The operation path is simple and does not require detours. There is no need to go around to the other side or flip the parts, which reduces the risk of interference and misassembly caused by multi-directional operation and improves disassembly and assembly efficiency.

[0302] The following describes in detail, with reference to the accompanying drawings, the operation of an air conditioner 2000 according to a specific embodiment of the present invention in cooling mode and heating mode. It should be understood that the following description is merely illustrative and should not be construed as a limitation of the present invention.

[0303] like Figure 1 , Figure 2 , Figures 31-41 As shown, an air conditioner 2000 according to a specific embodiment of the present invention includes a compressor 2100, a four-way valve 2200, an outdoor heat exchanger 2300, a heat exchange device 1000, and an indoor heat exchange unit 2400. The indoor heat exchange unit 2400 includes multiple indoor heat exchangers 2410, multiple indoor valves 2420, and multiple indoor filters 2430, with each of the multiple indoor heat exchangers 2410, multiple indoor valves 2420, and multiple indoor filters 2430 corresponding one-to-one. The heat exchange device 1000 includes a throttling assembly 100, a plate heat exchanger 200, a first filter 300, and a second filter 400. The throttling assembly 100 includes a valve island 10, a first valve 20, and a second valve 30.

[0304] In cooling mode, the flow direction of the heat exchange medium is as follows: Figure 31 As indicated by the solid arrow, the compressor 2100 compresses the low-pressure heat exchange medium gas and then discharges the high-pressure heat exchange medium gas. This high-pressure heat exchange medium gas flows sequentially through the four-way valve 2200 and the outdoor heat exchanger 2300. The heat exchange medium then flows through the heat exchange device 1000. The heat exchange medium flowing out from the first heat exchange channel 220 flows into the indoor heat exchange unit 2400 and finally returns to the compressor 2100 side; the heat exchange medium flowing out from the second heat exchange channel 230 returns directly to the compressor 2100 side. This process is repeated cyclically, achieving the cooling function at the indoor heat exchange unit 2400.

[0305] The following is a detailed description of the flow of the heat exchange medium in the heat exchange device 1000 under the refrigeration mode to illustrate its working principle.

[0306] After the heat exchange medium flows into the heat exchange device 1000, it passes through the first filter element 300 at the first mounting base 13. The heat exchange medium is filtered by the first filter element 300, which can reduce the impurities entrained in the heat exchange medium in the heat exchange device 1000, thus helping to ensure the normal working performance of the heat exchange device 1000.

[0307] Then, the heat exchange medium flows through the first flow path 101 of the valve island 10 and through the first valve 20. In the cooling mode, the first valve 20 is fully open (at its maximum opening), so the heat exchange medium is not throttled or depressurized in the first valve 20. Subsequently, part of the heat exchange medium flowing through the first valve 20 flows through the second flow path 102 and then directly into the first heat exchange channel 220 from the second interface 2201; the other part flows through the third flow path 103 and through the second valve 30, and then flows into the second heat exchange channel 230 through the third interface 2301. Here, the heat exchange medium in the first flow path 101 and the second flow path 102 is referred to as the main flow heat exchange medium, and the heat exchange medium in the first flow path 101 and the third flow path 103 is referred to as the auxiliary flow heat exchange medium.

[0308] Since the main heat exchange medium and the auxiliary heat exchange medium have already undergone impurity filtration in the first filter element 300, the operating performance of the first valve element 20 and the second valve element 30 is not easily affected by impurities. At this time, the opening of the second valve element 30 is small, thus throttling and depressurizing the auxiliary heat exchange medium, thereby reducing its pressure to below the saturation pressure corresponding to the current temperature of the auxiliary heat exchange medium. Consequently, the auxiliary heat exchange medium completely vaporizes, its temperature decreases, and then it flows into the second heat exchange channel 230 of the plate heat exchanger 200 through the third port 2301. The lower-temperature auxiliary heat exchange medium gas and the higher-temperature main heat exchange medium liquid exchange heat within the plate heat exchanger 200, causing the main heat exchange medium to cool down, and the auxiliary heat exchange medium is used to cool the main heat exchange medium. Subsequently, the main heat exchange medium flows out of the plate heat exchanger 200 from the first port 2202, and the auxiliary heat exchange medium flows out of the plate heat exchanger 200 from the fourth port 2302. The auxiliary heat exchange medium then flows back to the compressor 2100 inlet to enter the next cycle. The main heat exchange medium flows into the indoor heat exchange unit 2400, and after being filtered by the indoor filter 2430 and throttled by the indoor valve 2420, it flows into the indoor heat exchanger 2410 for heat exchange. After completing the heat exchange, the main heat exchange medium returns to the compressor 2100 inlet via the four-way valve 2200.

[0309] In heating mode, the flow direction of the heat exchange medium is as follows: Figure 31 As indicated by the dashed arrow, compressor 2100 compresses the low-pressure heat exchange medium gas and then discharges the high-pressure heat exchange medium gas. This high-pressure gas flows through four-way valve 2200 and into indoor heat exchange unit 2400. After heat exchange is completed in indoor heat exchanger 2410, it flows through fully open indoor valve 2420 and into heat exchange device 1000. The heat exchange medium flowing out of the first heat exchange channel 220 flows into outdoor heat exchanger 2300 and finally returns to compressor 2100; the heat exchange medium flowing out of the second heat exchange channel 230 returns directly to compressor 2100. This process is repeated cyclically, achieving heating function at indoor heat exchange unit 2400.

[0310] The following is a detailed description of the flow of the heat exchange medium in the heat exchange device 1000 under heating mode to illustrate its working principle.

[0311] After the heat exchange medium flows into the heat exchange device 1000, it passes through the second filter element 400 at the second mounting base 210. The second filter element 400 filters the heat exchange medium, which can reduce the impurities entrained in the heat exchange medium in the heat exchange device 1000, thus helping to ensure the normal working performance of the heat exchange device 1000.

[0312] Then, the heat exchange medium flows into the first heat exchange channel 220 of the plate heat exchanger 200 through the first interface 2202, and then flows from the second interface 2201 to the second flow path 102. A portion of the heat exchange medium in the second flow path 102 flows directly to the first flow path 101 and passes through the first valve 20, while another portion flows to the third flow path 103 and passes through the second valve 30 before flowing into the second heat exchange channel 230 through the third interface 2301. Here, the heat exchange medium in the first flow path 101 and the second flow path 102 is referred to as the main flow heat exchange medium, and the heat exchange medium in the first flow path 101 and the third flow path 103 is referred to as the auxiliary flow heat exchange medium.

[0313] Since the heat exchange medium has been filtered for impurities in the second filter element 400 before entering the plate heat exchanger 200, the operating performance of the first valve 20 and the second valve 30 is not easily affected by impurities. At this time, the opening of the first valve 20 is small, throttling and depressurizing the main heat exchange medium. For the auxiliary heat exchange medium, after being throttled and depressurized in the second valve 30, it flows into the second heat exchange channel 230 through the third port 2301, where it exchanges heat with the main heat exchange medium in the plate heat exchanger 200, using the main heat exchange medium to raise the temperature of the auxiliary heat exchange medium. Subsequently, the heat exchange medium in the second heat exchange channel 230 flows out of the plate heat exchanger 200 through the fourth port 2302, and finally returns to the compressor 2100 side.

[0314] Therefore, in cooling mode, the heat exchange device 1000 can reduce the temperature and pressure of the heat exchange medium entering the indoor heat exchange unit 2400, which helps to improve the cooling performance of the indoor heat exchange unit 2400. In heating mode, the heat exchange device 1000 can increase the temperature and pressure of the heat exchange medium entering the compressor 2100, which helps to increase the suction volume of the compressor 2100. In cooling mode, the heat exchange medium is filtered by the first filter 300 before flowing through the plate heat exchanger 200, the first valve 20 and the second valve 30; in heating mode, the heat exchange medium is filtered by the second filter 400 before flowing through the plate heat exchanger 200, the first valve 20 and the second valve 30, which can reduce impurities in the heat exchange medium in the heat exchange device 1000, thereby reducing the risk of blockage of the first valve 20 and the second valve 30 and improving the working efficiency of the air conditioner 2000.

[0315] The valve island 10, the first valve 20, and the second valve 30 are integrated into a single unit to form a throttle assembly 100. The first filter element 300, the second filter element 400, the plate heat exchanger 200, and the throttle assembly 100 are integrated into a single unit to form a heat exchange device 1000. This design makes the heat exchange device 1000 compact, occupies less space, and has a high degree of integration.

[0316] The following describes a heat pump device according to an embodiment of the present invention.

[0317] The heat pump equipment according to an embodiment of the present utility model includes an outdoor air conditioning unit 10000.

[0318] According to the embodiment of the present invention, a heat pump device is provided with an outdoor air conditioning unit 10000. The casing 4000 forms an installation space 411. A heat exchange device 1000 is installed in the installation space 411 and includes a plate heat exchanger 200, a throttling device assembly 100, and a valve island fastener 900. The throttling device assembly 100 includes a valve island 10. The valve island 10 is detachably installed on the plate heat exchanger 200 by the valve island fastener 900, so that the plate heat exchanger 200 and the throttling device assembly 100 are integrated, thereby improving the structural compactness between the plate heat exchanger 200 and the throttling device assembly 100, reducing the installation space 411 occupied by the heat exchange device 1000, and fixing the heat exchange device 1000 in the installation space 411 by the fixing component 500, ensuring that the heat exchange device 1000 is stably supported in the installation space 411, and improving the overall operational reliability of the heat pump device. Meanwhile, by having the valve island fastener 900 and the fixing component 500 oriented to the same side for disassembly and assembly, disassembly and assembly can be performed on the same side. The operation path is simple and does not require detours. There is no need to go around to the other side or flip the parts, which reduces the risk of interference and misassembly caused by multi-directional operation and improves disassembly and assembly efficiency.
