Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a fixed device, a heat exchanger assembly, and an outdoor unit for air conditioning. Background Technology

[0002] To improve heat exchange efficiency, the outdoor unit of the air conditioner uses a multi-layer heat exchanger. However, during transportation and use, this multi-layer structure is prone to displacement or misalignment, affecting the stability and reliability of the outdoor unit. Therefore, it is necessary to position and fix the multi-layer structure. Related technologies use clamps to hold the heat exchanger, but these clamps themselves lack reliable limiting, making them prone to detaching during vibration-induced transportation. This fails to effectively fix the heat exchanger, affecting its stability and causing vibration and abnormal noise. Utility Model Content

[0040] In the description of the embodiments of this application, it should be noted that the terms "height direction", "up", "down", "top", "bottom", "left", "right", "front", "back", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application 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. Therefore, they should not be construed as limitations on the embodiments of this application.

[0041] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 invention according to the specific circumstances.

[0042] This application provides a fixed device 10 for a heat exchanger 20 of an outdoor air conditioner unit. The heat exchanger 20 includes at least an inner heat exchange unit 21 and an outer heat exchange unit 22 stacked along a first direction.

[0043] The outdoor unit of an air conditioner is an important component of a split-type air conditioning system. It works in conjunction with the indoor unit to regulate indoor temperature and air quality. The outdoor unit is responsible for the compression and condensation of the refrigerant and for releasing heat into the outside air.

[0044] For example, heat exchanger 20 can be a condenser.

[0045] The heat exchanger 20 includes at least an inner heat exchange unit 21 and an outer heat exchange unit 22 stacked along a first direction, meaning that the heat exchanger 20 has at least a double-layer structure. Here, the heat exchanger 20 can also have a triple-layer structure or more, without limitation. The first direction can be the thickness direction of the heat exchanger 20.

[0046] In this embodiment, the heat exchanger 20 is described as having a double-layer structure.

[0047] The inner heat exchange unit 21 and the outer heat exchange unit 22 are stacked along the first direction, which can increase the contact area between the refrigerant and the outside air, increase the total amount of heat released to the outside environment per unit time, and improve the heat exchange efficiency.

[0048] The heat exchange areas of the inner heat exchange unit 21 and the outer heat exchange unit 22 can be the same or different. For example, in some embodiments, the heat exchange area of ​​the inner heat exchange unit 21 can be half that of the outer heat exchange unit 22; in this case, the heat exchanger 20 can be referred to as a 1.5-row heat exchanger. In other embodiments, the heat exchange area of ​​the inner heat exchange unit 21 is the same as that of the outer heat exchange unit 22; in this case, the heat exchanger 20 can be referred to as a double-row heat exchanger.

[0049] This application also provides a heat exchanger assembly, including a heat exchanger 20 and a fixing device 10 in any embodiment of this application. The heat exchanger 20 includes at least an inner heat exchange unit 21 and an outer heat exchange unit 22 stacked along a first direction.

[0050] Please see Figure 5 and Figure 8 Along the second direction, the outer heat exchange unit 22 extends beyond the inner heat exchange unit 21 and is bent. In this embodiment, the heat exchanger 20 can be a 1.5-row heat exchanger. Part of the outer heat exchange unit 22 is stacked with the inner heat exchange unit 21, and another part extends beyond the inner heat exchange unit 21 and is bent. This helps to increase the heat exchange area of ​​the heat exchanger 20, improve the cooling efficiency of the outdoor unit of the air conditioner, and at the same time, reduce the impact on the overall size of the outdoor unit of the air conditioner.

[0051] This application also provides an outdoor air conditioning unit, including a cover, a chassis 30, and a heat exchanger assembly according to any embodiment of this application. The cover is disposed on the top side of the chassis 30 and forms a receiving area. The heat exchanger assembly is located in the receiving area, and the fixing device 10 is supported on the chassis 30.

[0052] The housing serves as the exterior component of the outdoor unit of the air conditioner and, together with the chassis 30, forms a housing area that provides housing space and installation protection for the internal heat exchanger assembly.

[0053] For example, the outdoor unit of the air conditioner also includes a compressor. Taking the outdoor unit of the air conditioner as an example of a refrigeration cycle, the compressor compresses the low-temperature, low-pressure gaseous refrigerant from the indoor unit, turning it into a high-temperature, high-pressure gas. The high-temperature, high-pressure gaseous refrigerant enters the heat exchanger 20 and exchanges heat with the air in the outside environment. The gaseous refrigerant is converted into a liquid and sent back to the indoor unit to start a new refrigeration cycle.

[0054] Please see Figures 1 to 7 The fixing device 10 includes a first fixing member 11 and a second fixing member 12.

[0055] The first fastener 11 is used to connect to the inner heat exchange unit 21 along the second direction.

[0056] The second fastener 12 is provided with a clamping groove 12a, which is used to clamp the bottom side of the heat exchanger 20.

[0057] The first fixing member 11 is connected to the inner heat exchange unit 21 along the second direction. The connection between the first fixing member 11 and the inner heat exchange unit 21 can fix the relative position of the first fixing member 11 with respect to the inner heat exchange unit 21 along the second direction, making it difficult for the first fixing member 11 to move relative to the inner heat exchange unit 21.

[0058] For example, the first fixing member 11 can be detachably connected to the inner heat exchange unit 21 along the second direction to facilitate adjustment of the position of the first fixing member 11 or the inner heat exchange unit 21. The detachable connection method can be snap-fit, screw-fit, etc., and is not limited here.

[0059] The clamping groove 12a is used to clamp the bottom side of the heat exchanger 20, meaning that the clamping groove 12a can clamp the inner heat exchange unit 21 and the outer heat exchange unit 22 from bottom to top, so that the inner heat exchange unit 21 and the outer heat exchange unit 22 will not move or displace in the first direction.

[0060] For example, please refer to Figure 1 and Figure 2 The clamping groove 12a is provided through the second direction to facilitate clamping the heat exchanger 20.

[0061] It is understandable that when the number of layers in heat exchanger 20 is greater than two, the number of layers held by clamping groove 12a is also greater than two.

[0062] This application describes the embodiment of the fixing device 10 in conjunction with the bottom of the heat exchanger 20. In other embodiments, the fixing device 10 may also be configured to cooperate with the top of the heat exchanger 20.

[0063] One of the first fixing member 11 and the second fixing member 12 is provided with a locking part 113, and the other is provided with a locking position 12b. The second fixing member 12 is connected to the first fixing member 11 and can be flipped up and down relative to the first fixing member 11 to the side of the first fixing member 11 along the second direction, so that the locking part 113 and the locking position 12b are locked together along the top and bottom direction. The first direction, the second direction, and the top and bottom direction intersect each other.

[0064] It is understandable that the first fixing member 11 may be provided with a locking part 113 and the second fixing member 12 may be provided with a locking position 12b, or the first fixing member 11 may be provided with a locking position 12b and the second fixing member 12 may be provided with a locking part 113.

[0065] The second fixing member 12 being able to rotate up and down relative to the first fixing member 11 means that the second fixing member 12 can rotate up and down relative to the first fixing member 11 from the connection point between the two. Here, the second fixing member 12 and the first fixing member 11 can be directly connected to each other, or the connection point between the two can be formed as a thin-walled structure, so that the second fixing member 12 can rotate up and down relative to the first fixing member 11. There is no limitation here.

[0066] For example, the first fixing member 11 can be connected and engaged with the inner heat exchange unit 21 first. At this time, the second fixing member 12 does not clamp the inner heat exchange unit 21. After the first fixing member 11 is installed, the second fixing member 12 is flipped upward relative to the first fixing member 11 to clamp the inner heat exchange unit 21 and the outer heat exchange unit 22. At this time, the locking part 113 can engage with the locking position 12b. That is, through the engagement of the locking part 113 and the locking position 12b, the first fixing member 11 and the second fixing member 12 are self-locked, and the first fixing member 11 and the second fixing member 12 cannot move relative to each other.

[0067] The locking part 113 and the locking position 12b are locked together in the top-bottom direction. This means that when a force is applied to the fixing device 10 from the top-bottom direction, the locking relationship between the locking part 113 and the locking position 12b will not change, and the first fixing member 11 and the second fixing member 12 will not separate or shift.

[0068] It is understood that the first fixing member 11 can be fixed relative to the inner heat exchange unit 21 in the second direction, the clamping groove 12a restricts the displacement of the inner heat exchange unit 21 and the outer heat exchange unit 22 in the first direction, and the locking part 113 cooperates with the locking position 12b to lock the first fixing member 11 and the second fixing member 12, so that the fixing device 10 can reliably limit the position in both the second direction and the top and bottom directions, so as to effectively fix the inner heat exchange unit 21 and the outer heat exchange unit 22.

[0069] The fixing device 10 is supported on the chassis 30. The fixing device 10 can obtain structural support through the chassis 30, thereby providing reliable support for the heat exchanger 20, and further realizing positioning and limiting along the top and bottom direction through the cooperation of the chassis 30 and the heat exchanger 20.

[0070] The first direction, the second direction, and the top-bottom direction can be mutually perpendicular. For example, the second direction can be... Figure 6 The left and right directions in the middle.

[0071] Understandably, in related technologies, taking a 1.5-row heat exchanger as an example, the fixing clamp cannot clamp the heat exchanger along the second direction. The clamping groove formed by the fixing clamp holds the inner and outer heat exchange units from the bottom side. The fixing clamp has no limiting position along the second direction, making it prone to movement relative to the heat exchanger, leading to fixing failure. This causes the inner and outer heat exchange units to shift or even separate, resulting in vibration and abnormal noise. Simultaneously, the fixing clamp lacks reliable upper and lower limiting positions, leaving the inner heat exchange units without reliable support, causing them to sag. This results in unevenness of the heat exchanger, increasing piping stress and affecting the service life of the outdoor air conditioning unit.

[0072] The fixing device 10 provided in this embodiment is connected to the inner heat exchange unit 21 via a first fixing member 11. The clamping groove 12a of the second fixing member 12 clamps and fixes the heat exchanger 20, and the locking part 113 and the locking position 12b achieve interlocking after assembly. This ensures that the fixing device 10 is reliably limited in both the second direction and the top and bottom directions, making it less likely to loosen or fall off the heat exchanger 20. The connection stability between the fixing device 10 and the heat exchanger 20 is high, which can effectively reduce noise and abnormal sounds during transportation and use, and extend the service life of the heat exchanger 20. At the same time, the flip design of the first fixing member 11 and the second fixing member 12 can also increase the ease of assembly, making it easier to gradually achieve the positioning and fixation of the fixing device 10 and the heat exchanger 20, and the installation is simple and reliable. Of course, the setting of the first fixing member 11 and the second fixing member 12 can also increase the structural strength of the fixing device 10 and support it on the chassis 30 of the outdoor air conditioning unit, achieving stable positioning and support.

[0073] In some embodiments, please refer to Figure 3 and Figure 4 The clamping groove 12a has a first support surface 11a, and the first fixing member 11 has a second support surface 12c. The first fixing member 11 cooperates with the inner heat exchange unit 21 in the second direction through the second support surface 12c, and the first support surface 11a is connected to the second support surface 12c.

[0074] In the initial position, the position of the first support surface 11a is flush with the position of the second support surface 12c, wherein the initial position is the position of the second fixing member 12 when it is not subjected to external force.

[0075] The first support surface 11a is used to fit tightly against the bottom surface of the heat exchanger 20, and the second support surface 12c is used to cooperate with the inner heat exchange unit 21 along the second direction. The second support surface 12c and the inner heat exchange unit 21 can be spaced apart or in abutting fit.

[0076] In the initial position, the second fixing member 12 is not subjected to external force, that is, the second fixing member 12 is in a natural state. At this time, the locking part 113 is separated from the locking position 12b.

[0077] In the initial position, the first support surface 11a and the second support surface 12c are flush, meaning there is no height difference between them. This facilitates the connection between the first fixing member 11, the second fixing member 12, and the heat exchanger 20, reducing the chance of interference. It also allows for the direct installation of a thin-walled structure 10a at the connection point, enabling the second fixing member 12 to flip relative to the first fixing member 11, thus simplifying the structure of the fixing device 10. Furthermore, it facilitates the molding of the fixing device 10.

[0078] In some embodiments, please refer to Figure 1 and Figure 2 When the locking part 113 is locked in the locking position 12b, the first support surface 11a is perpendicular to the second support surface 12c. That is, the included angle between the first support surface 11a and the second support surface 12c is 90°. In this way, the first fixing member 11 can form a structure that surrounds the inner heat exchange unit 21 on three sides together with the clamping groove 12a while connecting with the inner heat exchange unit 21, so as to achieve reliable fixation. Of course, the perpendicularity between the first support surface 11a and the second support surface 12c can also facilitate the tight fit between the first support surface 11a and the inner heat exchange unit 21 along the second direction, increasing the stability of the fit.

[0079] In some embodiments, please refer to Figure 3 The connection between the first fixing member 11 and the second fixing member 12 is formed as a thin-walled structure 10a, so that the second fixing member 12 can be flipped up and down relative to the first fixing member 11.

[0080] The thin-walled structure 10a refers to a structure where the connection between the first fixing member 11 and the second fixing member 12 is thinned to give it a certain degree of flexibility and bendability. Under the action of external force, the thin-walled structure 10a allows the second fixing member 12 to flip up and down relative to the first fixing member 11. The thin-walled structure 10a can be formed as a hingeless flexible connection structure.

[0081] In this embodiment, the thin-walled structure 10a enables the second fixing member 12 to flip relative to the first fixing member 11 without the need for an additional rotating connection structure (rotating shaft or hinge), making the structure of the fixing device 10 simpler and reducing the number of parts and manufacturing costs of the fixing device 10. The thin-walled structure 10a can be formed integrally, making it easier to form the fixing device 10 into an integral structure.

[0082] For example, in some embodiments, the fixing device 10 is an integral structure, that is, the fixing device 10 is manufactured as a single piece. During assembly, the fixing device 10 can be directly connected to the heat exchanger 20 without the need for additional connection of the fixing device 10. The fixing device 10 has a simple structure, high structural strength, and is also easy to reduce manufacturing costs and improve production efficiency.

[0083] For example, the fixing device 10 is integrally injection molded.

[0084] In other embodiments, the fixing device 10 includes a connecting shaft, and a first fixing member 11 and a second fixing member 12 are rotatably connected about the connecting shaft.

[0085] In this embodiment, the first fixing member 11 and the second fixing member 12 are rotatably connected by a connecting shaft. The second fixing member 12 can rotate up and down relative to the first fixing member 11 around the connecting shaft. The connecting shaft can increase the structural stability and structural strength of the fixing device 10.

[0086] The connecting shaft can be a pin, a rotating shaft, etc., and there are no restrictions here.

[0087] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 9 The locking part 113 includes a latch that protrudes from the side of the first fixing member 11 away from the inner heat exchange unit 21 along the first direction; or, the latch protrudes from the side of the second fixing member 12 away from the inner heat exchange unit 21 along the first direction.

[0088] The locking position 12b includes a locking groove, and the latch is inserted into the locking groove in a first direction.

[0089] In this embodiment, the engagement of the latch and the locking groove allows the engagement of the first fixing member 11 and the second fixing member 12 to be located on the side away from the inner heat exchange unit 21. While achieving the limiting, it reduces damage to the heat exchanger 20 and increases the reliability of the engagement. At the same time, the simple structure of the latch and the locking groove reduces the assembly difficulty and increases the structural simplicity of the fixing device 10.

[0090] In some embodiments, the size of the latch outside the locking groove along the first direction is 1 mm to 3 mm, for example, 1 mm, 1.2 mm, 1.4 mm, 1.5 mm, 1.8 mm, 2 mm, 2.1 mm, 2.3 mm, 2.5 mm, 2.7 mm, 3 mm, etc.

[0091] It should be noted that the dimension of the latch outside the locking groove refers to the dimension of the latch protruding outside the locking groove along the first direction after it is inserted into the locking groove. This dimension can reflect the amount of latch engagement in the locking groove.

[0092] Understandably, if the engagement amount between the latch and the locking groove is too small, the latch is likely to come out of the locking groove. If the engagement amount between the latch and the locking groove is too large, it is inconvenient to operate and may damage the latch or the locking groove.

[0093] In this embodiment, the dimensions of the latch and the locking groove are designed to ensure that the latch and the locking groove have a suitable engagement amount. This facilitates the self-locking engagement of the first fixing member 11 and the second fixing member 12 while ensuring high self-locking reliability of the first fixing member 11 and the second fixing member 12.

[0094] The number of latches and locking slots can be one or more, and there is no limitation. For example, there is one of each.

[0095] The specific structure of the first fastener 11 is not limited.

[0096] In some embodiments, please refer to Figure 1 and Figure 2 The first fixing member 11 includes a connecting plate 111 and a first flap 112. The connecting plate 111 is connected to the inner heat exchange unit 21, and the first flap 112 is connected to the connecting plate 111 and extends in a second direction from the connection with the connecting plate 111. When the locking part 113 is locked in the locking position 12b, the first flap 112 and the second fixing member 12 together clamp the heat exchanger 20. The locking part 113 protrudes from the side of the first flap 112 away from the heat exchanger 20.

[0097] For example, the connecting plate 111 may extend generally in the top-bottom direction.

[0098] The first flap 112 extends from the connection point with the connecting plate 111 in a second direction, that is, the first flap 112 can be approximately perpendicular to the first support surface 11a.

[0099] It should be noted that the positions of the connecting plate 111 and the first flap 112 are described with the fixing device 10 in the state of being in conjunction with the heat exchanger 20.

[0100] The locking part 113 protrudes from the side of the first flap 112 away from the heat exchanger 20, that is, the locking position 12b is provided on the second fixing member 12. The engagement of the locking part 113 and the locking position 12b is located away from the heat exchanger 20, so it will not affect the heat exchanger 20. At the same time, it will not affect the clamping of the clamping groove 12a on the heat exchanger 20.

[0101] For example, please refer to Figure 1 The locking part 113 includes a latch that protrudes from the side of the first flap 112 away from the heat exchanger 20. The cross-sectional area of ​​the latch can gradually decrease along the first direction away from the first flap 112 to reduce assembly difficulty.

[0102] When the locking part 113 is locked in the locking position 12b, the first flap 112 and the second fixing member 12 together clamp the heat exchanger 20. This means that the first flap 112 can also contact the inner heat exchange unit 21 and clamp and limit the heat exchanger 20 together with the clamping groove 12a.

[0103] In this embodiment, the locking part 113 is disposed on the first flap 112. When assembling the interlock, the second fixing member 12 can be flipped so that the locking position 12b cooperates with the locking part 113, increasing the assembly simplicity. At the same time, when the locking part 113 cooperates with the locking position 12b, the first flap 112 and the clamping groove 12a can also clamp the heat exchanger 20 together, further increasing the contact area between the fixing device 10 and the heat exchanger 20, and increasing the reliability of the limiting fixation.

[0104] The construction of the second fastener 12 is not limited.

[0105] In some embodiments, please refer to Figures 1 to 4 The second fastener 12 includes a base plate 123, a first clamping plate 121 and a second clamping plate 122. The first clamping plate 121 and the second clamping plate 122 are spaced apart along the first direction and are respectively connected to the top side of the base plate 123 to jointly define the clamping groove 12a.

[0106] For example, the cross-section of the groove 12a along the top and bottom direction can be generally formed as U-shaped.

[0107] When used in conjunction with the heat exchanger 20, the first clamping plate 121 and the second clamping plate 122 respectively abut against the inner heat exchange unit 21 and the outer heat exchange unit 22 along the first direction, and the bottom plate 123 provides support for the heat exchanger 20 so as to clamp and fix the heat exchanger 20 together.

[0108] The first clamping plate 121 has a notch 121a on the side near the first fixing member 11. The second fixing member 12 includes a mounting plate 124. The mounting plate 124 is connected to the first clamping plate 121 on the side away from the inner heat exchange unit 21 along the first direction and extends in the second direction. The locking position 12b penetrates the mounting plate 124 along the first direction. The first flip plate 112 is disposed in the notch 121a and is stacked with the mounting plate 124 along the first direction.

[0109] In this embodiment, the mounting plate 124 is located on the side of the first flap 112 away from the inner heat exchange unit 21 along the first direction. The mounting plate 124 and the inner heat exchange unit 21 are spaced apart. The notch 121a allows the first clamping plate 121 and the first flap 112 to avoid each other and can simultaneously clamp the heat exchanger 20. In this way, the cooperation between the first flap 112 and the mounting plate 124 is located on the side of the first flap 112 away from the inner heat exchange unit 21, which is safe and reliable. The mounting plate 124 can limit and fix the first flap 112, increasing the reliability of the fixing device 10.

[0110] In some embodiments, please refer to Figure 1 and Figure 7At least one of the first clamping plate 121 and the second clamping plate 122 is provided with a guide slope 12d on the side away from the bottom plate 123. The guide slope 12d extends obliquely away from the heat exchanger 20 in the direction from the bottom side to the top side.

[0111] In this embodiment, the guide slope 12d is disposed on the side of the first clamping plate 121 and / or the second clamping plate 122 away from the bottom plate 123. It can guide the assembly during the process of the clamping groove 12a and the heat exchanger 20, and leave a margin to reduce assembly damage to the heat exchanger 20 and increase assembly reliability.

[0112] For example, both the first clamping plate 121 and the second clamping plate 122 are provided with guide slopes 12d.

[0113] In some embodiments, please refer to Figures 1 to 4 , Figure 9 The base plate 123 is provided with at least one through drainage hole 123a.

[0114] It is understandable that condensate will inevitably be produced during the operation of a heat exchanger.

[0115] Therefore, in this embodiment, the drain hole 123a can be provided to drain the condensate generated by the heat exchanger 20 out of the fixing device 10, thereby increasing the operational reliability of the heat exchanger 20.

[0116] The number of drain holes 123a is not limited; there can be one or more. For example, there are multiple drain holes 123a to increase drainage efficiency.

[0117] The shape of the drain hole 123a is not limited. For example, it can be a round hole, a square hole, a triangular hole, etc., and there is no limitation here.

[0118] For example, please refer to Figures 1 to 4 , Figure 9 The drain hole 123a is a round hole.

[0119] The diameter of the drain hole 123a can be 5mm to 15mm, for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc. In this way, drainage can be facilitated while ensuring the structural strength of the fixing device 10.

[0120] In some embodiments, please refer to Figures 1 to 4 , Figure 9The side surface of the base plate 123 facing away from the clamping groove 12a is the first surface; the first surface has a recessed area 123c and a non-recessed area 123b. The non-recessed area 123b is used to abut against the chassis 30 of the outdoor unit of the air conditioner. The recessed area 123c is spaced apart from the chassis 30. The drain hole 123a is located in the non-recessed area 123b. The recessed area 123c extends to the edge of the base plate 123 to connect the drain hole 123a with the external environment.

[0121] In this embodiment, the recessed area 123c enables the drainage hole 123a to communicate with the external environment, so as to guide the water flow of the drainage hole 123a to the external environment and increase the drainage smoothness.

[0122] The recessed area 123c can be formed into a rectangle or other shapes.

[0123] For example, please refer to Figure 1 The recessed area 123c is formed into a rectangle, and the area of ​​the rectangle can be 25 cm². 2 (square centimeters) - 225 cm 2 For example, 25 cm 2 36cm 2 49 cm 2 64 cm 2 72 cm 2 80 cm 2 100 cm 2 125 cm 2 144cm 2 169cm 2 180cm 2 225 cm 2 In this way, both smooth drainage and structural strength can be balanced.

[0124] The connection method between the first fixing member 11 and the inner heat exchange unit 21 is not limited.

[0125] In some embodiments, please refer to Figures 6 to 8 The first fixing member 11 has a slot 11b, and a hook 114 is formed in the slot 11b. The hook 114 is used to engage with the U-shaped tube 211 of the inner heat exchange unit 21.

[0126] For example, the card slot 11b is formed on the connecting plate 111.

[0127] It should be noted that the inner heat exchange unit 21 includes refrigerant pipes and fins. The refrigerant pipes include straight pipes and U-shaped pipes 211. The U-shaped pipes 211 are used to connect two adjacent straight pipes. The U-shaped pipes 211 are mounted on one end of the inner heat exchange unit 21 along the second direction to support and fix the refrigerant pipes.

[0128] In this embodiment, the first fixing member 11 is connected to the U-shaped tube 211 through the hook 114, which effectively connects the first fixing member 11 to the inner heat exchange unit 21. The connection is simple and reliable, and the first fixing member 11 is not easy to fall off the inner heat exchange unit 21.

[0129] The number of card slots 11b is unlimited; for example, please refer to [link to example]. Figure 1 There are two card slots 11b, which are spaced apart along the top and bottom direction. Each card slot 11b is provided with a card hook 114.

[0130] Understandably, the design of the card slot 11b can be based on the U-shaped tube 211.

[0131] In some embodiments, the U-shaped tube 211 protrudes from the outside of the hook 114 by 1mm to 5mm along the second direction, for example, 1mm, 1.5mm, 1.8mm, 2mm, 2.3mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. The size of the U-shaped tube 211 protruding from the outside of the hook 114 is the engagement amount between the U-shaped tube 211 and the hook 114. This engagement amount can increase the ease of operation while ensuring docking stability.

[0132] In some embodiments, please refer to Figure 2 and Figure 8 The hook 114 has an inclined surface 11c on the side facing the inner heat exchange unit 21. The inclined surface 11c guides the insertion of the U-shaped tube 211 to increase the ease of assembly.
