For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Reference below Figure 1-Figure 8 An air conditioner 100 according to an embodiment of the present invention is described.

[0046] like Figure 1-Figure 8 As shown, an air conditioner 100 according to an embodiment of the present invention includes: a casing 10 having an air inlet 101 and an air outlet 102 .

[0047] The air conditioner 100 further includes a compressor 20 disposed within the casing 10 .

[0048] The air conditioner 100 also includes a tubular heat exchanger 30, which is arranged in the casing 10. The tubular heat exchanger 30 has a water path and a refrigerant path. The refrigerant path is connected to the compressor 20. The water path is used to dissipate heat from the refrigerant path, thereby utilizing cold water for heat exchange. No additional structures such as a wind wheel are required. Compared with the traditional condenser plus wind wheel structure, the size of the entire machine can be greatly reduced.

[0049] The air conditioner 100 also includes an electronic control system 50, which is arranged in the casing 10. The electronic control system 50 forms an air duct 501, and the air duct 501 is connected to the air inlet 101 and the air outlet 102. The electronic control system 50 includes an electronic control module 51 and a cooling fan 52. At least a part of the electronic control module 51 is located in the air duct 501. The cooling fan 52 is located at one end of the air duct 501, and the cooling fan 52 is used to dissipate heat from the electronic control module 51.

[0050] That is to say, in this embodiment, by setting up a tubular heat exchanger 30, cold water is used to dissipate heat in the refrigerant circuit. Since the tubular heat exchanger 30 does not dissipate heat for the electronic control module 51, the heat of the electronic control module 51 tends to continue to increase within a certain period of time. When the temperature reaches a certain threshold, the protection of the electronic control module 51 will be triggered, causing the air conditioner 100 to shut down or not work. For this reason, by setting an air duct 501 in the electronic control system 50 and a cooling fan 52 on the air duct 501, the disadvantage that the tubular heat exchanger 30 cannot dissipate heat for the electronic control module 51 is avoided, and the electronic control module 51 is dissipated by the cooling fan 52. The cooling fan 52 generates airflow, and the airflow takes away the heat of the electronic control module 51 when flowing through the electronic control system 50, thereby achieving heat dissipation of the electronic control module 51, thereby ensuring that the air conditioner 100 can work normally for a long time.

[0051] According to the air conditioner 100 of the embodiment of the utility model, water cooling is used for heat exchange, which can reduce the size of the whole machine compared to the air cooling design. The cooling fan 52 is used to dissipate heat for the electronic control module 51. The airflow no longer flows through other heat-generating parts, thereby achieving direct heat dissipation of the electronic control module 51 with good heat dissipation effect. Therefore, on the basis of achieving heat dissipation for each component, the size of the whole machine is reduced, the body is made compact, the installation of the air conditioner 100 is facilitated, and the adaptability of the air conditioner 100 is improved.

[0052] It can be understood that according to the structure of the air conditioner 100, the air conditioner 100 here can be understood as a conventional air conditioner outdoor unit. Usually, the air conditioner outdoor unit is installed outdoors, but in the present embodiment, due to the small size of the whole machine, the air conditioner 100 can be installed indoors, for example, on the ceiling, to achieve a built-in installation of the outdoor unit. Compared with the traditional outdoor unit installation, there is no need for a dedicated outdoor unit position, no need to drill through the wall, and it is not restricted by the outdoor unit position, the bracket on the exterior wall, the wall perforation, etc. The operation is relatively simple and easy to install.

[0053] like Figure 3 and Figure 4 As shown, in some embodiments, the electric control system 50 includes a housing 53, the housing 53 has an air outlet 502, the air outlet 502 is connected to the air duct 501, the cooling fan 52 is installed on the housing 53, the cooling fan 52 and the air outlet 502 are arranged opposite to each other, and the electric control module 51 is arranged between the air outlet 502 and the cooling fan 52, thereby allowing the air flow to form convection, which is beneficial to effective blowing and cooling of the electric control module 51.

[0054] like Figure 4 As shown, in some embodiments, the housing 10 includes a chassis 11, one of the outer shell 53 and the chassis 11 has a card slot 16, and the other of the outer shell 53 and the chassis 11 has a card protrusion 534, the card protrusion 534 is suitable for being inserted into the card slot 16, and the outer shell 53 is connected to the chassis 11, thereby installing and fixing the electronic control system 50 on the housing 10, and a pre-positioned structural form is formed by the card protrusion 534 and the card slot 16 being carded together, thereby simplifying the connection process and improving the convenience of assembly.

[0055] like Figure 4-Figure 7 As shown, in some embodiments, the shell 53 includes a bottom plate 533 on one side close to the chassis 11, and a portion of the bottom plate 533 is arched in a direction away from the chassis 11 to form a latching protrusion 534, and the latching protrusion 534 is adjacent to the edge of the bottom plate 533. Therefore, when the shell 53 is placed on the chassis 11, the shell 53 can be moved horizontally so that the bottom plate 533 can move relative to the chassis 11. The chassis 11 has a latching slot 16, and the edge of one side of the bottom plate 533 where the latching protrusion 534 is provided can move in a direction close to the latching slot 16, so that the latching protrusion 534 slides into the latching slot 16, so that the latching protrusion 534 and the latching slot 16 cooperate, thereby achieving pre-positioned installation.

[0056] like Figure 5 As shown, a latching protrusion 534 is respectively provided at both ends of one side edge of the bottom plate 533, and the two latching protrusions 534 are arranged at intervals at both ends of the bottom plate 533 along the third direction F3. The bottom plate 533 is roughly square, and the two latching protrusions 534 are arranged at two corners of the bottom plate 533. The two corners can correspond to the two corners in the length direction of the bottom plate 533, so that the two sides of the shell 53 can be pre-positioned to prevent the shell 53 from rotating and offsetting.

[0057] That is to say, the pre-positioning installation of the electric control system 50 can be realized by only pushing the shell 53 horizontally to the predetermined position, which is convenient for installation. There is no need to lift the shell 53 again, and there will be no interference during the horizontal movement of the shell 53, which is convenient for installation. In addition, through the design of this structure, the electric control system 50 can be installed into the casing 10 from one side, which is convenient for maintenance and loading and unloading in a small space. Through the cooperation of the protrusion 534 and the slot 16, the electric control system 50 can be easily installed.

[0058] like Figure 4 As shown, in some embodiments, a side of the chassis 11 close to the outer shell 53 has a retaining rib 15, one end of the retaining rib 15 is connected to the chassis 11, and the other end of the retaining rib 15 is spaced apart from the chassis 11, a slot 16 is formed between the retaining rib 15 and the chassis 11, and an insertion opening of the slot 16 can be formed between the other end of the retaining rib 15 and the chassis 11.

[0059] That is to say, by setting the retaining rib 15, the electronic control system 50 can be pre-positioned for installation, which has a simple structure and is easy to manufacture. In addition, the retaining rib 15 can also be integrally formed on the chassis 11 through a stamping process, which further simplifies the manufacturing process, simplifies the structure, and facilitates the manufacturing of the overall structure.

[0060] like Figure 6 and Figure 7 As shown, in some embodiments, a fixed flange 535 is provided on one side edge of the bottom plate 533, and the fixed flange 535 extends obliquely in a direction inclined to the bottom plate 533. The chassis 11 has a connecting portion, and the fixed flange 535 is fixedly connected to the connecting portion by fasteners.

[0061] like Figure 5-Figure 7 As described, the fixed flange 535 and the locking protrusion 534 are arranged on the edges of the opposite sides of the bottom plate 533 along the first direction F1, and the fixed flange 535 extends downwardly in a direction away from the edge where the locking protrusion 534 is located. A boss protruding upward is provided on the chassis 11, and the upper surface of the boss is roughly horizontal. A side edge of the boss in the first direction F1 has a retaining rib 15, and the other side edge of the boss in the first direction F1 forms a connecting portion. The electronic control system 50 can be placed on the boss of the chassis 11, and the housing 53 is pushed in the direction close to the retaining rib 15 along the first direction F1 until the locking protrusion 534 is locked into place with the locking groove 16, at which time the fixed flange 535 can abut against the connecting portion of the edge of the boss and be fixedly connected by fasteners.

[0062] like Figure 7As shown, in some embodiments, the housing 53 includes: a first cover plate 531 and a second cover plate 532, the first cover plate 531 and the second cover plate 532 are connected, and an air duct 501 is defined therebetween, the cooling fan 52 is mounted on the first cover plate 531, the electric control module 51 is disposed in the air duct 501, and the electric control module 51 is connected to at least one of the first cover plate 531 and the second cover plate 532, thereby facilitating the manufacture of the housing 53 and the installation of the cooling fan 52 and the electric control module 51.

[0063] like Figure 6 and Figure 7 As shown, in some embodiments, one of the first cover plate 531 and the second cover plate 532 has a buckle 5313, and the other of the first cover plate 531 and the second cover plate 532 has a latch position 5324, and the buckle 5313 is engaged with the latch position 5324, thereby achieving the connection between the first cover plate 531 and the second cover plate 532, and at the same time allowing the first cover plate 531 and the second cover plate 532 to be disassembled to facilitate the maintenance of the electronic control system 50.

[0064] like Figure 5 and Figure 6 As shown, in some embodiments, the electric control system 50 further has a wiring terminal 54, which is located on the side of the first cover plate 531 away from the air duct 501, thereby integrating the wiring terminal 54 on the outside of the electric control system 50, which is beneficial to wiring and improves the convenience of assembly.

[0065] like Figure 7 As shown, in some embodiments, the first cover plate 531 includes an integrally formed first cover body 5311 and a side bracket 5312, the side bracket 5312 is used to install the cooling fan 52, and the second cover plate 532 includes an integrally formed second cover body 5321, a top plate 5322 and a side baffle 5323, wherein the second cover body 5321 is arranged opposite to the first cover body 5311, the top plate 5322, the side baffle 5323 and the side bracket 5312 are located between the second cover body 5321 and the first cover body 5311, the side baffle 5323 is arranged opposite to the side bracket 5312 and has an air outlet 502, the top plate 5322 and the side baffle 5323 are arranged at intervals to form an avoidance gap 536, the setting of the avoidance gap 536 enables the upper part of the electric control module 51 to communicate with the outside world, forming a gap that is easy to operate, so that the internal structure can be repaired and replaced without completely disassembling the electric control system 50.

[0066] like Figure 7As shown, in some embodiments, the second cover plate 532 also includes a bottom plate 533, the first cover body 5311 is supported on the bottom plate 533, and the first cover body 5311 is connected to the bottom plate 533, that is, the second cover plate 532 includes a second cover body 5321, a top plate 5322, a side baffle 5323 and a bottom plate 533, the top plate 5322 and the bottom plate 533 are arranged opposite to each other, the second cover body 5321, the side baffle 5323 are connected to the bottom plate 533, that is, the second cover body 5321, the top plate 5322, the side baffle 5323 and the bottom plate 533 are formed as one piece, thereby reducing parts and components and facilitating the assembly of the electronic control system 50.

[0067] Of course, the bottom plate 533 may also be a separate structural component, thereby facilitating the manufacturing and forming of each component.

[0068] In some embodiments, the first cover plate 531 is a plastic part, and the second cover plate 532 is a sheet metal part. By partially using plastic parts and partially using sheet metal parts, the weight of the housing 53 can be reduced and the manufacturing cost can be reduced on the basis of realizing the installation of various components.

[0069] In some embodiments, the air conditioner 100 also includes a filter, and a filter is provided at the air inlet 101 and / or the air outlet 102, and the filter is fixedly connected to the casing 10. Here, a filter can be added to the air outlet, or the air outlet itself can be made into a filter structure, so as to enhance the insect and dust prevention capabilities.

[0070] Of course, the filter can also be detachably connected to the casing 10. By adding a detachable filter to the air outlet, while enhancing its insect and dustproof capabilities, it can be replaced and cleaned to improve the use effect.

[0071] It should be noted that the air inlet 101 and the air outlet 102 here can be a large open opening, or can be composed of multiple holes, which is not limited here.

[0072] like Figure 3 As shown, in some embodiments, the compressor 20 is arranged to extend along a first direction F1, the size of the compressor 20 along the first direction F1 is larger than the size along the second direction F2, and the tubular heat exchanger 30 is arranged along an axis parallel to the second direction F2, so that the tubular heat exchanger 30 surrounds the outer periphery of the compressor 20.

[0073] It can be understood that the first direction F1 is substantially the axial direction of the compressor 20, the second direction F2 is substantially the radial direction of the compressor 20, and the axis of the tubular heat exchanger 30 is parallel to the second direction F2, so that the tubular heat exchanger 30 can be located at the periphery of the compressor 20 in the axial direction of the compressor 20, such as Figure 3As shown, the tubular heat exchanger 30 can be horizontally arranged on the periphery of the compressor 20, so that the structural layout is compact, and the tubular heat exchanger 30 can share the height space with the compressor 20, thereby reducing the height space occupied by the whole machine and reducing the height size of the whole machine.

[0074] Furthermore, the air conditioner 100 with a small height dimension can be arranged on the ceiling to achieve concealed installation of the air conditioner 100 .

[0075] like Figure 8 As shown, in some embodiments, the tubular heat exchanger 30 includes an inner tube 301 and an outer tube 302, the outer tube 302 is sleeved on the outside of the inner tube 301, one of the inner tube 301 and the outer tube 302 is connected to water to form a water path, and the other of the inner tube 301 and the outer tube 302 is connected to the compressor 20 to form a refrigerant path, that is, the tubular heat exchanger 30 is a shell and tube heat exchanger, and the water path and the refrigerant path in the inner tube 301 and the outer tube 302 form a heat exchange system through contact, wherein the inner tube of the tubular heat exchanger 30 may be for water to flow, and the outer tube may be for refrigerant to flow, so that the refrigerant path is sandwiched between water and external air, and water and external air can absorb the heat of the refrigerant at the same time to improve the condensation effect. Of course, the outer tube of the tubular heat exchanger 30 may be for water to flow, and the inner tube may be for refrigerant to flow.

[0076] Of course, the tubular heat exchanger 30 can also be a heat exchanger of other structural forms, such as a structure in which multiple tubes are arranged side by side in a radial direction of the tube to form an annular structure, so that the tubular heat exchanger 30 can be arranged around the outer periphery of the compressor 20.

[0077] like Figure 8 As shown, in some embodiments, the outer periphery of the tubular heat exchanger 30 has a fixed bracket 31, and the fixed bracket 31 includes a first connecting section 311 and a second connecting section 312. The first connecting section 311 is connected to the tubular heat exchanger 30, and the second connecting section 312 is perpendicular to the first connecting section 311, and the second connecting section 312 is fixedly connected to the chassis 11, thereby facilitating the fixed connection between the tubular heat exchanger 30 and the chassis 11, and improving the convenience and stability of fixing the tubular heat exchanger 30.

[0078] The first connecting section 311 can be welded to the outer periphery of the tubular heat exchanger 30 to improve the reliability of the connection between the first connecting section 311 and the tubular heat exchanger 30 and facilitate the assembly of the tubular heat exchanger 30 on the chassis 11 .

[0079] like Figure 8 As shown, the fixing brackets 31 include two fixing brackets 31 , which are arranged oppositely on both sides of the tubular heat exchanger 30 , so that the tubular heat exchanger 30 is clamped between the two fixing brackets 31 , which can improve the stability of the tubular heat exchanger 30 .

[0080] Of course, the fixing brackets 31 may include more brackets to improve the fixing effect of the tubular heat exchanger 30 .

[0081] In some embodiments, the air conditioner 100 also includes: a water circuit control module 40, which is disposed in the casing 10, the water circuit control module 40 is connected to the water circuit of the tubular heat exchanger 30, and the water circuit control module 40 is located between the electronic control system 50 and the compressor 20.

[0082] The water circuit control module 40 and the tubular heat exchanger 30 are arranged along the second direction F2, so that the water circuit control module 40 can be arranged on one side of the tubular heat exchanger 30, thereby making full use of the space in the second direction F2. Figure 3 and Figure 4 As shown, in the second direction F2, the size of the tubular heat exchanger 30 is smaller than that of the compressor 20, thereby leaving a certain space on one side of the tubular heat exchanger 30. The second direction F2 can be an up and down direction, where the water circuit control module 40 can be arranged above the tubular heat exchanger 30. Of course, the water circuit control module 40 can also be arranged below the tubular heat exchanger 30.

[0083] Of course, the water channel of the tubular heat exchanger 30 can also be directly connected to the faucet of the user's indoor water pipe, and the faucet switch can be used to directly control the water inlet and outlet, so as to realize heat exchange using tap water, which can further reduce the size of the whole machine.

For example, the mounting shell 41 can be supported on the tubular heat exchanger 30, thereby improving the stability of the mounting shell 41 and reducing the probability of the water circuit control module 40 shaking. At the same time, the abutment of the two can also reduce the assembly gap between the two, thereby reducing the size of the whole machine and improving the compactness of the structure. Of course, the mounting shell 41 can also be installed at the bottom of the tubular heat exchanger 30, and the tubular heat exchanger 30 is supported on the mounting shell 41 to improve the stability of the tubular heat exchanger 30.

The cover 43 can be fitted with the outer surface of a section of the tubular heat exchanger 30, that is, the curvature of the cover 43 is the same as the curvature of the outer surface of the tubular heat exchanger 30. The cover 43 can be covered on the outside of the tubular heat exchanger 30, thereby improving the reliability of the cooperation between the mounting shell 41 and the tubular heat exchanger 30 and improving the stability of the overall structure.

[0086] In some embodiments, the cover 43 includes multiple covers 43, and the multiple covers 43 are fitted with the outer surfaces of multiple sections of the tubular heat exchanger 30. Each cover 43 extends along the extension direction of a section of the corresponding tubular heat exchanger 30, and the extension directions of at least two cover covers 43 are different. For example, the tubular heat exchanger 30 includes a section extending along the first direction F1 and also includes a section extending along the third direction F3. The lower side of the mounting shell 41 includes at least two cover covers 43, one cover cover 43 is fitted with a section of the tubular heat exchanger 30 extending along the first direction F1, and the other cover cover 43 is fitted with a section of the tubular heat exchanger 30 extending along the third direction F3, thereby playing a limiting role in two directions, reducing the probability of shaking of the mounting shell 41, and improving the stability of the overall structure.

[0087] like Figure 3 and Figure 4 As shown, in some embodiments, the mounting shell 41 is fixedly connected to the electronic control system 50, thereby making full use of the structure within the air conditioner 100, improving the stability of the water circuit control module 40, and realizing the connection of multiple structures, thereby improving the compactness of the overall structure.

[0088] like Figure 4 As shown, a portion of the mounting shell 41 extends toward the direction approaching the electric control system 50 to form an extension plate 44. The extension plate 44 can be overlapped on the top of the electric control system 50, or extend into the bottom of the electric control system 50. The extension plate 44 has a fixing hole, and the electric control system 50 has a matching hole. The fixing holes and the matching holes are penetrated by fasteners to achieve a fixed connection between the mounting shell 41 and the electric control system 50.

[0090] Of course, the air inlet 101 can also be set on the top cover 13, or between two adjacent side panels 12, or on the chassis 11; correspondingly, the air outlet 102 can also be set on the top cover 13, or between two adjacent side panels 12, or on the chassis 11.

[0091] In addition, the bottom chassis 11 and the top cover 13 are arranged opposite to each other in the second direction F2 , thereby reducing the size of the housing 10 in the second direction F2 to a certain extent.

[0093] Among them, when the air conditioner 100 is equipped with an embedded indoor unit, both the indoor unit and the outdoor unit can be hidden and installed in the ceiling 200, and only the panel (including the air outlet) and the return air outlet are visible to the user at the bottom of the ceiling 200; when the air conditioner 100 is equipped with a ceiling-mounted indoor unit, the user can see the ceiling-mounted indoor unit and the connecting pipe, and the remaining structure is hidden in the ceiling, thereby realizing hidden installation of the outdoor unit.

[0094] In some embodiments, at least two of the multiple side panels 12 are integrally formed, for example, two side panels 12 are integrally formed, such as being integrally manufactured through a bending process. The two side panels 12 can also be welded into an integral part through a welding process, and then fixedly connected to another side panel. Of course, all side panels 12 can also be integrally formed, thereby effectively reducing parts and reducing the complexity of assembly.

[0095] In some embodiments, multiple side panels 12 are connected by fasteners, so that each side panel 12 is a separate structural member, which facilitates the manufacturing and forming of each side panel 12, maintenance and disassembly, etc., and also facilitates the transportation and handling of the structure.

[0096] In some embodiments, the top cover 13 is integrally formed with at least one of the multiple side panels 12. For example, the top cover 13 is integrally formed with a side panel 12, for example, they are integrally manufactured through a bending process. The top cover 13 and a side panel 12 can also be welded into an integral part through a welding process, and then fixedly connected to another side panel. Of course, the top cover 13 can also be integrally formed with multiple side panels 12 at the same time, so that after the functional components of the air conditioner 100 are installed on the chassis 11, the top cover 13 and the side panel 12 are covered and installed on the chassis 11 to realize the assembly of the whole machine, thereby effectively reducing parts and reducing the complexity of assembly.

[0097] In some embodiments, the top cover 13 is fixedly connected to at least one of the multiple side panels 12, so that the top cover 13 is a separate structural member, which facilitates the manufacturing and molding of the top cover 13, maintenance and disassembly, etc., and transportation and handling of the top cover 13.

The second direction F2 can be an up and down direction, where the valve and pipeline module 60 can be arranged above the tubular heat exchanger 30. Of course, the valve and pipeline module 60 can also be arranged below the tubular heat exchanger 30.

[0099] In addition, the mounting plate 61 is connected to the housing 10 to realize the installation of the valve pipeline module 60. For example, the mounting plate 61 extends along the third direction F3, and the two ends of the mounting plate 61 are respectively connected to two oppositely arranged side plates 12, thereby not only fixing the mounting plate 61, but also increasing the strength and stability of the housing 10.

[0100] The pipelines include refrigerant pipelines and water pipelines. Preferably, the inlets and outlets of the pipelines are on the same side, so as to facilitate the operation of connecting the refrigerant pipes and the water pipes on the same side.

[0104] When the air conditioner is turned on, check whether the electronic control module is started;

[0105] When the electronic control module is started, the cooling fan is controlled to rotate.

[0106] In the above embodiment, after the electronic control module is started, the cooling fan is controlled to rotate to continuously dissipate heat for the electronic control module, that is, to achieve real-time heat dissipation of the electronic control module in the working state, effectively reduce the temperature of the electronic control module, and thus ensure that the air conditioner can work normally for a long time.
