Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a heat exchanger bracket and an air conditioner. Background Technology

[0002] The heat exchanger is the core component of the indoor unit of an air conditioner. During cooling, it absorbs heat from the air through the evaporation of low-temperature refrigerant to achieve indoor temperature reduction.

[0003] The heat exchanger of a cabinet air conditioner is generally connected to the cabinet shell via a bracket structure to fix the heat exchanger inside the cabinet. Existing brackets for fixing heat exchangers typically consist of several parts assembled together, including a top bracket, two side brackets, and a drip tray.

[0004] However, the assembled heat exchanger bracket requires its own assembly before the air conditioner unit can be assembled, increasing the complexity of the production process. Most importantly, the various components of the bracket are fixed together with screws, etc. During long-term operation of the air conditioner, factors such as equipment vibration and alternating hot and cold temperatures can cause the connections to loosen, affecting the bracket's ability to securely hold the heat exchanger in place. Utility Model Content

[0005] The problem solved by this invention is that the existing split-type evaporator bracket is troublesome to assemble, and the screws used to fix the parts of the evaporator bracket may loosen due to vibration and other factors, which will affect the stability of the bracket.

[0006] To address the aforementioned issues, this utility model provides a heat exchanger bracket and an air conditioner. The heat exchanger bracket is integrally molded, eliminating the need for pre-assembly during air conditioner assembly, thus making assembly more convenient. The integrally molded heat exchanger bracket also eliminates the need for screws to fix components, reducing assembly errors and the risk of loosening.

[0007] In the first aspect, this utility model provides a heat exchanger bracket for use in an indoor cabinet air conditioner. The heat exchanger bracket includes an integrally formed upper bracket, side brackets, and a water collection tank. The side brackets include two side brackets, which are respectively disposed at both ends of the upper bracket and the water collection tank along the length direction. One end of each side bracket is connected to the upper bracket, and the other end is connected to the water collection tank. The heat exchanger mounting cavity is formed by the upper support, the two side supports, and the water collection tank. The heat exchanger mounting cavity is used to install the heat exchanger.

[0008] This application integrates the upper support, side supports, and water collection tank into a single molded structure. This integrated structure effectively enhances the overall strength and structural stability of the heat exchanger support. Compared to traditional split-type heat exchanger supports, it reduces the pre-assembly process, making assembly more convenient. The integrated design also eliminates the need for screws to secure components, reducing assembly errors and the risk of loosening. Furthermore, the upper support, two side supports, and water collection tank together form a heat exchanger mounting cavity. When the heat exchanger is installed within this cavity, the upper and side supports effectively support the top and sides, while the water collection tank supports the bottom. This multi-point support ensures uniform support in all directions, further enhancing its stability during operation.

[0009] In an optional embodiment, the heat exchanger mounting cavity has an air inlet side and an air outlet side; The upper bracket has a first flange on the side located on the air inlet side, facing the heat exchanger mounting cavity; Both of the side supports have a second flange on the side located on the air inlet side, facing the heat exchanger mounting cavity; The first flange and / or the second flange are provided with a plurality of first fixing holes, which are used for screws to pass through to fix the heat exchanger bracket to the heat exchanger.

[0010] This application features a first flange extending inward on the air inlet side of the upper support, and second flanges extending inward on the air inlet side of both side supports. This design allows the first flange and the two second flanges to collectively surround the upper and sides of the heat exchanger, forming a limiting support structure for the heat exchanger in the air inlet direction. This effectively prevents displacement or tilting of the heat exchanger during installation or operation, improving the overall structural stability. Multiple first fixing holes are provided on the first flange and / or second flange, allowing for quick and detachable rigid connection between the heat exchanger and the support during assembly by screwing into these holes. This enables rapid assembly, ensures the heat exchanger's secure installation during operation, and facilitates subsequent maintenance or replacement. The multiple first fixing holes allow for selection of appropriate fixing positions based on the specific dimensions of the heat exchanger and installation requirements during actual assembly, thereby enhancing the applicability and assembly flexibility of the support.

[0011] In an optional embodiment, the upper bracket is provided with a third flange on the side of the air outlet side, in a direction away from the heat exchanger mounting cavity, and the third flange is provided with a plurality of second fixing holes; The second fixing hole is used for screws to pass through to fix the top of the heat exchanger to the third flange, and enables the third flange to be connected to the back panel of the indoor cabinet unit.

[0012] This application features an outward-facing third flange on the air outlet side of the upper bracket, with multiple second fixing holes on this flange. This allows the third flange to engage with screws through these holes, securing the connecting piece at the top of the heat exchanger to the heat exchanger bracket. Simultaneously, the third flange also establishes a structural connection with the rear panel of the indoor unit, thereby enhancing the overall stability and support strength of the heat exchanger within the unit. In other words, a single set of screws can achieve a secure connection between the heat exchanger, the heat exchanger bracket, and the rear panel of the indoor unit, making assembly more convenient.

[0013] In an optional embodiment, the second flange is provided with a groove on one side of the air outlet side. The groove extends along the length of the side support to avoid the copper tubes on both sides of the heat exchanger and to guide the condensate on the side support located on the air outlet side into the water collection tank.

[0014] This application incorporates a groove on the outlet side of the second flange, extending along the length of the side support. This provides clearance for the copper tubes on both sides of the heat exchanger, preventing interference between the tubes and the heat exchanger support during assembly and improving assembly reliability. Furthermore, the groove effectively guides condensate generated on the outlet side of the side support into a collection tank, preventing dripping or accumulation of condensate on the support surface during operation and thus enhancing the overall leak-proof performance. The groove's extension direction aligns with the length of the side support, allowing condensate to flow smoothly under gravity and ultimately collect in the collection tank, achieving effective collection and guidance of condensate.

[0015] In an optional embodiment, the water collection tank is provided with a supporting structure, and the bottom end of the heat exchanger can be supported by the supporting structure.

[0016] This application features a supporting structure protruding from the water collection tank. The bottom of the heat exchanger can be supported by this supporting structure, which limits the installation position of the heat exchanger in the height direction, ensuring its stable placement within the heat exchanger mounting cavity and facilitating alignment during assembly. Furthermore, the supporting structure raises the bottom of the heat exchanger relative to the bottom plate of the water collection tank by a certain height. When condensate drips from the surface of the heat exchanger, the gap between the bottom of the heat exchanger and the bottom plate of the water collection tank allows the condensate to flow smoothly into the water collection tank and along the bottom plate towards the drain outlet. This prevents condensate from accumulating at the bottom of the heat exchanger, reducing the risk of corrosion from accumulated water and improving the drainage efficiency of the water collection tank.

[0017] In an optional embodiment, the support structure has a first limiting boss, which can abut against the side of the heat exchanger located on the air outlet side when the bottom end of the heat exchanger is supported by the support structure.

[0018] This application provides a first limiting boss on the support structure. After the heat exchanger is installed into the heat exchanger mounting cavity, its bottom is supported by the support structure, and the lower part of the air outlet side can be effectively positioned and fixed by the limiting effect of the first limiting boss. This restricts the degree of freedom of the heat exchanger in the air outlet direction, eliminating the need for additional screws. This can improve assembly efficiency and also avoid opening holes in the side wall of the water collection tank.

[0019] In an optional embodiment, the bottom plate of the water collection tank is provided with a plurality of spaced second limiting protrusions near the air inlet side. The second limiting protrusions are spaced apart from the rear plate of the water collection tank, and the gap between any two adjacent second limiting protrusions forms a water inlet trough. When the bottom end of the heat exchanger is supported by the support structure, the second limiting boss can abut against the side of the heat exchanger located on the air inlet side, so that the side of the heat exchanger located on the air inlet side is spaced apart from the rear plate of the water collection tank.

[0020] This application incorporates multiple spaced second limiting protrusions on the bottom plate of the water collection tank near the air inlet side. When the bottom of the heat exchanger is supported by the structure, the side of the heat exchanger located on the air inlet side abuts against the second limiting protrusions. Combined with the first limiting protrusions, this effectively limits the forward and backward movement of the heat exchanger. Most importantly, it prevents the air inlet side of the heat exchanger from contacting the rear plate of the water collection tank, allowing condensate from the air inlet side of the heat exchanger to flow into the water collection tank. The water channel formed by the gap between any two adjacent second limiting protrusions guides water droplets dripping or condensing from the air inlet side of the heat exchanger along the surface of the bottom plate and is then concentrated and guided to the drain outlet or water collection chamber via the water channel, thereby improving overall drainage efficiency and preventing condensate from stagnating or overflowing in the water collection tank.

[0021] In an optional embodiment, the water collection tank includes a bottom plate, side plates disposed on both sides of the bottom plate along its length, a front plate disposed on the front side of the bottom plate, and a rear plate disposed on the rear side of the bottom plate. The bottom plate, the side plates, the front plate, and the rear plate enclose a water collection cavity. The bottom ends of the two side supports are respectively connected to the two side plates, and the bottom ends of the second flanges disposed on the two side plates are respectively connected to both sides of the rear plate along its length. The base plate has a drain outlet on one side along its length. A portion of the base plate near the rear plate is inclined to form a water guiding surface, and the water guiding surface is inclined with water guiding ribs facing the drain outlet.

[0022] This application designs a section of the base plate near the rear plate as an inclined water-guiding surface. This inclined surface quickly guides water from below the heat exchanger's bottom to a lower position, preventing the bottom of the heat exchanger from being submerged in condensate and thus extending its service life. The water-guiding surface is also equipped with guide ribs that slope towards the drain outlet. These ribs quickly direct the condensate flowing from the heat exchanger to the drain outlet, preventing water from accumulating in the collection tank and submerging the bottom of the heat exchanger.

[0023] In an optional embodiment, the first flange, the second flange, and the rear plate of the water collection tank are connected in sequence; The first flange is provided with a fourth flange facing the air inlet side; The second flange is provided with a fifth flange facing the air inlet side; The rear plate of the water collection tank is provided with a sixth flange facing the air inlet side, and the sixth flange is inclined towards the top of the heat exchanger support. The fourth flange, the fifth flange, and the sixth flange are connected in sequence.

[0024] This application connects the first flange, the second flange, and the rear plate sequentially to form a closed structure, which improves the overall structural strength. The fourth, fifth, and sixth flanges, connected sequentially to form a closed structure, enhance structural stability and guide condensate. When hot air enters the heat exchanger mounting cavity from the air inlet side, condensate forms on the heat exchanger surface after heat exchange. Some of this condensate flows down the fifth flange on the air inlet side, providing initial guidance and preventing direct dripping. The sixth flange's inclined design further directs the condensate flowing down the fifth flange into the collection tank, preventing accumulation between the support and the heat exchanger, thus improving the overall drainage efficiency and leak-proof performance.

[0025] Secondly, this utility model provides an air conditioner, including an indoor cabinet unit; The indoor cabinet unit includes a housing, a heat exchanger, and a heat exchanger bracket as described in any of the foregoing embodiments; The heat exchanger bracket is fixed inside the housing, and the heat exchanger is installed inside the heat exchanger mounting cavity.

[0026] The air conditioner provided in this application, by integrating the upper bracket, side brackets, and water collection tank into a single molded structure, effectively improves the overall strength and structural stability of the heat exchanger bracket. Compared to traditional split-type heat exchanger brackets, it reduces the pre-assembly process, making air conditioner assembly more convenient. The one-piece molded heat exchanger bracket also eliminates the need for screws to fix components, reducing assembly errors and the risk of loosening. Furthermore, the upper bracket, two side brackets, and water collection tank together form a heat exchanger mounting cavity. When the heat exchanger is installed within this cavity, the upper and side brackets effectively support the top and sides of the heat exchanger, while the water collection tank supports the bottom. This multi-point support method ensures uniform support for the heat exchanger in all directions, further enhancing its stability during operation. Attached Figure Description

Detailed Implementation

[0029] The heat exchanger of a cabinet air conditioner is generally connected to the cabinet shell via a bracket structure to fix the heat exchanger inside the cabinet. Existing brackets for fixing heat exchangers typically consist of several parts assembled together, including a top bracket, two side brackets, and a drip tray.

[0030] However, the assembled heat exchanger bracket requires its own assembly before the air conditioner unit can be assembled, increasing the complexity of the production process. Most importantly, the various components of the bracket are fixed together with screws, etc. During long-term operation of the air conditioner, factors such as equipment vibration and alternating hot and cold temperatures can cause the connections to loosen, affecting the bracket's ability to securely hold the heat exchanger in place.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Please refer to Figure 1 This embodiment provides an air conditioner 300, which is a floor-standing unit. The air conditioner 300 includes an indoor floor-standing unit 310. The indoor floor-standing unit 310 is generally installed indoors and can adjust the indoor air temperature according to needs.

[0033] In this embodiment, the indoor unit 310 includes a housing 311, a heat exchanger 312, and a heat exchanger bracket 100. The heat exchanger bracket 100 is fixed inside the housing 311, and the heat exchanger 312 is mounted on the heat exchanger bracket 100.

[0034] It should be noted that in some embodiments of this application, the indoor unit 310 can be square or round in shape. In terms of air supply type, the indoor unit 310 can be an axial flow unit, a centrifugal unit, or a cross-flow unit. The fixed positions of the heat exchanger bracket 100 and the heat exchanger 312 can be set according to specific needs. For example, in a centrifugal unit, the centrifugal fan 320 is located below the housing 311, and the heat exchanger bracket 100 and the heat exchanger 312 are inclinedly arranged in the middle of the housing 311. The centrifugal fan 320 sends air upwards, which is then heat-exchanged by the heat exchanger 312 and discharged from the air outlet of the housing 311. In cross-flow or axial flow units, the heat exchanger 312 and the heat exchanger bracket 100 are generally vertically aligned with the position of the air inlet on the inner side of the housing 311.

[0035] Please refer to Figures 1 to 4 In this embodiment, the heat exchanger support 100 includes an integrally formed upper support 110, side supports 130, and a water collection tank 150. Two side supports 130 are respectively disposed at both ends of the upper support 110 and the water collection tank 150 along their length, with one end of each side support 130 connected to the upper support 110 and the other end connected to the water collection tank 150. The upper support 110, the two side supports 130, and the water collection tank 150 enclose a heat exchanger mounting cavity 170, which is used to mount the heat exchanger 312.

[0036] In this embodiment, the upper support 110, the side supports 130, and the water collection tank 150 are designed as an integral structure. This forms a single, integrated structure, effectively improving the overall strength and structural stability of the heat exchanger support 100. Compared to traditional split-type heat exchanger supports 100, this reduces the pre-assembly process, making assembly more convenient. The integrally formed heat exchanger support 100 also eliminates the need for screws to fix the components, reducing assembly errors and the risk of loosening. Furthermore, the upper support 110, the two side supports 130, and the water collection tank 150 together form a heat exchanger mounting cavity 170. When the heat exchanger 312 is installed within the mounting cavity 170, the upper support 110 and the side supports 130 effectively support the top and sides of the heat exchanger 312, while the water collection tank 150 supports the bottom of the heat exchanger 312. This multi-point support method ensures that the heat exchanger 312 is evenly supported in all directions, further enhancing its stability during operation.

[0037] It should be noted that, taking the heat exchanger bracket 100 as an example of its application in a centrifugal cabinet air conditioner, both side brackets 130 are inclined relative to the water collection tank 150. When the heat exchanger bracket 100 is installed at an incline in the middle of the housing 311, the water collection tank 150 is horizontally positioned, and both side brackets 130 extend upwards and backwards at an incline. However, when the heat exchanger bracket 100 is applied to a cross-flow or centrifugal cabinet air conditioner, it is only necessary to ensure that both side brackets 130 are perpendicular to the water collection tank 150.

[0038] It should also be noted that the heat exchanger bracket 100 is roughly rectangular in shape, and the heat exchanger 312 is embedded in the heat exchanger mounting cavity 170 of the heat exchanger bracket 100.

[0039] Please refer to Figures 1 to 4 Taking a centrifugal square cabinet air conditioner as an example, the housing 311 includes a rear panel 314, side panels 315, a front panel 316, a lower panel 317, a base 318, and a top cover 319. There are two side panels 315, installed on the left and right sides of the rear panel 314. The front panel 316 is installed on the top front side of the side panels 315, and the lower panel 317 is installed on the bottom front side of the two side panels 315. The base 318 is installed at the bottom. The top cover 319 is installed at the top, together forming an installation cavity. A heat exchanger bracket 100 is installed at an angle within the installation cavity, and a heat exchanger 312 is installed on the heat exchanger bracket 100, dividing the installation cavity into upper and lower chambers. A centrifugal fan 320 is located in the lower chamber, with its outlet corresponding to the heat exchanger bracket 100, and its inlet corresponding to the air inlet of the rear panel 314. The front panel 316 has an air outlet. The centrifugal fan 320 can draw in air from outside the casing 311 and send it to the heat exchanger 312 for heat exchange. The air that has been heated will be sent out through the air outlet to achieve indoor temperature regulation.

[0040] Please refer to Figure 4 , Figure 5 and Figure 6 Furthermore, the heat exchanger mounting cavity 170 has an air inlet side 171 and an air outlet side 172. The upper bracket 110 has a first flange 111 on the side of the air inlet side 171 facing the heat exchanger mounting cavity 170. Both side brackets 130 have second flanges 131 on the side of the air inlet side 171 facing the heat exchanger mounting cavity 170. The second flanges 131 are provided with multiple first fixing holes 133 for screws to pass through in order to fix the heat exchanger bracket 100 to the heat exchanger 312.

[0041] In this embodiment, a first flange 111 is provided on the upper bracket 110 on the air inlet side 171 facing the heat exchanger mounting cavity 170, and two second flanges 131 are provided on the side of the two side brackets 130 on the air inlet side 171 facing the heat exchanger mounting cavity 170. This design allows the first flange 111 and the two second flanges 131 to surround the upper part and both sides of the heat exchanger 312, forming a limiting support structure 151 for the heat exchanger 312 in the air inlet side 171 direction. This effectively prevents the heat exchanger 312 from shifting or tilting during installation or operation, improving the stability of the overall structure. Multiple first fixing holes 133 are provided on the second flanges 131, allowing for quick and detachable rigid connection between the heat exchanger 312 and the heat exchanger bracket 100 during assembly by screwing into the first fixing holes 133. This enables rapid assembly, ensures the secure installation of the heat exchanger 312 during operation, and facilitates subsequent maintenance or replacement operations. The arrangement of multiple first fixing holes 133 allows for the selection of appropriate fixing positions based on the specific dimensions and installation requirements of the heat exchanger 312 during actual assembly, thereby enhancing the applicability and assembly flexibility of the bracket.

[0042] In some other embodiments of this application, a plurality of first fixing holes 133 may also be provided on the first flange 111.

[0043] It should be noted that during assembly, the heat exchanger 312 is usually installed in the heat exchanger mounting cavity 170 first, and then the heat exchanger 312 and the heat exchanger bracket 100 are pre-assembled by screws driven through the first fixing hole 133.

[0044] Please refer to Figure 4 , Figure 7 and Figure 8 Furthermore, the upper bracket 110 has a third flange 113 on the side of the air outlet side 172 facing away from the heat exchanger mounting cavity 170. The third flange 113 has a plurality of second fixing holes 114. The second fixing holes 114 are used for screws to pass through to fix the top of the heat exchanger 312 to the third flange 113, and to connect the third flange 113 to the back panel 314 of the indoor cabinet unit 310.

[0045] In this embodiment, an outward-facing third flange 113 is provided on the side of the upper bracket 110 located on the air outlet side 172, and multiple second fixing holes 114 are provided on the third flange 113. This allows the third flange 113 to engage with screws through the second fixing holes 114, achieving a fixed connection between the connecting piece at the top of the heat exchanger 312 and the heat exchanger bracket 100. Simultaneously, the third flange 113 can also establish a structural connection with the rear panel 314 of the indoor cabinet unit 310, thereby enhancing the stability and support strength of the heat exchanger 312 within the cabinet unit. In other words, a single set of screws can achieve a fixed connection between the heat exchanger 312, the heat exchanger bracket 100, and the rear panel 314 of the indoor cabinet unit 310, making assembly more convenient.

[0046] It should be noted that, generally, a bent sheet metal part 321 is welded to the top of the heat exchanger 312, and this sheet metal part 321 has multiple fixing holes. Secondly, the top of the rear panel 314 of the cabinet housing has a folded edge, and mounting holes corresponding to the fixing holes are provided on the folded edge. During assembly, the third folded edge 113 is overlapped onto the folded edge, and then the heat exchanger 312 is installed in the heat exchanger mounting cavity 170, with the sheet metal part 321 abutting against the outside of the third folded edge 113. Finally, a set of screws is used to secure all three components.

[0047] Please refer to Figure 4 In this embodiment, the second flange 131 is provided with a groove 135 on one side of the air outlet side 172. The groove 135 extends along the length of the side support 130 to avoid the copper tubes on both sides of the heat exchanger 312 and to guide the condensate of the side support 130 on the air outlet side 172 into the water collection tank 150.

[0048] In this embodiment, a groove 135 is provided on one side of the second flange 131 located on the air outlet side 172, and the groove 135 extends along the length of the side support 130. This provides clearance for the copper tubes on both sides of the heat exchanger 312, preventing interference between the copper tubes and the heat exchanger support 100 during assembly, thus improving assembly reliability. Furthermore, the groove 135 effectively guides the condensate generated on the side support 130 located on the air outlet side 172 into the water collection tank 150, preventing condensate from dripping or accumulating on the support surface during equipment operation, thereby improving the overall leak-proof performance. The extension direction of the groove 135 is consistent with the length direction of the side support 130, allowing the condensate to flow smoothly along the groove 135 under gravity and ultimately flow into the water collection tank 150, thus achieving effective collection and guidance of the condensate.

[0049] Please refer to Figure 4 , Figure 5 and Figure 6In this embodiment, the water collection tank 150 is provided with a support structure 151, and the bottom end of the heat exchanger 312 can be supported by the support structure 151.

[0050] In this embodiment, a support structure 151 protrudes from the water collection tank 150. The bottom end of the heat exchanger 312 can be supported by the support structure 151. The support structure 151 can limit the installation position of the heat exchanger 312 in the height direction, so that it is stably located in the heat exchanger mounting cavity 170, which facilitates alignment during assembly. Secondly, the support structure 151 can also raise the bottom end of the heat exchanger 312 relative to the bottom plate 155 of the water collection tank 150 by a certain height. When condensate drips from the surface of the heat exchanger 312, since there is a certain gap between the bottom end of the heat exchanger 312 and the bottom plate 155 of the water collection tank 150, the condensate can flow smoothly into the water collection tank 150 and flow along the bottom plate 155 of the water collection tank 150 to the drain outlet 160. This can prevent condensate from accumulating at the bottom end of the heat exchanger 312, reduce the risk of corrosion of the heat exchanger 312 by accumulated water, and improve the drainage efficiency of the water collection tank 150.

[0051] Specifically, the support structure 151 is configured as an "L" shape with a 90° tilt, with its horizontal section connected to the rear plate 158 of the water collection tank 150 and its vertical section connected to the bottom plate 155 of the water collection tank 150. The horizontal section forms a support surface, which is perpendicular to the side bracket 130. After the heat exchanger 312 is installed in the heat exchanger mounting cavity 170, the support surface supports the bottom of the heat exchanger 312. In this embodiment, the support structure 151 is configured as an "L" shape with a 90° tilt, so that the support structure 151 can provide support without affecting the drainage of water from the water collection tank 150 to the drain outlet 160.

[0052] Furthermore, the support structure 151 includes two supports, which are respectively arranged on both sides of the water collection tank 150 along its length to support the two ends of the bottom of the heat exchanger 312.

[0053] In this embodiment, the support structure 151 is provided with a first limiting boss 152. When the bottom end of the heat exchanger 312 is supported by the support structure 151, the first limiting boss 152 can abut against the side of the heat exchanger 312 located on the air outlet side 172.

[0054] In this embodiment, a first limiting boss 152 is provided on the support structure 151. After the heat exchanger 312 is installed into the heat exchanger mounting cavity 170, its bottom is supported by the support structure 151, and the lower area of ​​the air outlet side 172 can be effectively positioned and fixed by the limiting effect of the first limiting boss 152. This restricts the degree of freedom of the heat exchanger 312 in the direction of the air outlet side 172, eliminating the need for additional screws. This can improve assembly efficiency and also avoid opening holes in the side wall of the water collection tank 150.

[0055] It should be noted that the first limiting boss 152 protrudes from the support surface. The first limiting boss 152 can be provided on the support surfaces of all support structures 151, or it can be provided on the support surfaces of only some support structures 151. Specifically, it can be designed according to actual needs and spatial layout. In this embodiment, since the position of one support structure 151 corresponds to the drain outlet 160 of the water collection tank 150, to avoid interference between the two, the first limiting boss 152 is only provided on the support structure 151 on the other side.

[0056] In some other embodiments of this application, the first limiting boss 152 may also protrude from the side plates 156 on both sides of the length direction of the water collection tank 150, so as to abut against the front side of the bottom of the heat exchanger 312.

[0057] Please refer to Figure 4 , Figure 5 and Figure 6 In this embodiment, the bottom plate 155 of the water collection tank 150 is provided with a plurality of spaced second limiting protrusions 153 near the air inlet side 171. The second limiting protrusions 153 are spaced apart from the rear plate 158 of the water collection tank 150, and the gap between any two adjacent second limiting protrusions 153 forms a water inlet channel 154. When the bottom end of the heat exchanger 312 is supported by the support structure 151, the second limiting protrusions 153 can abut against the side of the heat exchanger 312 located on the air inlet side 171, so that the side of the heat exchanger 312 located on the air inlet side 171 is spaced apart from the rear plate 158 of the water collection tank 150.

[0058] In this embodiment, multiple spaced second limiting protrusions 153 are provided on the bottom plate 155 of the water collection tank 150 near the air inlet side 171. When the bottom of the heat exchanger 312 is supported by the support structure 151, the lower end of the heat exchanger 312, located on the air inlet side 171, abuts against the second limiting protrusions 153. Combined with the first limiting protrusions 152, this achieves front-to-back limiting of the heat exchanger 312. Most importantly, it prevents the air inlet side 171 of the heat exchanger 312 from abutting against the rear plate 158 of the water collection tank 150, allowing the condensate from the air inlet side 171 of the heat exchanger 312 to flow along the air inlet side 171 into the water collection tank 150. The water channel 154 formed by the gap between any two adjacent second limiting protrusions 153 can guide water droplets dripping from the air inlet side 171 of the heat exchanger 312 or generated by condensation to flow along the surface of the bottom plate 155, and be concentrated and guided to the drain outlet 160 or the water collection chamber 159 through the water channel 154, thereby improving the overall drainage efficiency and preventing condensate from stagnating or overflowing in the water collection channel 150.

[0059] Specifically, the water collection tank 150 includes a base plate 155, side plates 156 disposed on both sides of the base plate 155 along its length, a front plate 157 disposed on the front side of the base plate 155, and a rear plate 158 disposed on the rear side of the base plate 155. The base plate 155, side plates 156, front plate 157, and rear plate 158 enclose a water collection cavity 159. The bottom ends of the two side supports 130 are respectively connected to the two side plates 156, and the bottom ends of the second flanges 131 disposed on the two side plates 156 are respectively connected to both sides of the rear plate 158 along its length. A drain outlet 160 is provided on one side of the base plate 155 along its length. A portion of the base plate 155 near the rear plate 158 is inclined to form a water guiding surface 161, and water guiding ribs 162 are inclined towards the drain outlet 160 on the water guiding surface 161.

[0060] In this embodiment, a portion of the base plate 155 near the rear plate 158 is configured as an inclined water guiding surface 161. The inclined water guiding surface 161 can quickly guide the water below the bottom of the heat exchanger 312 to a lower position, thereby preventing the bottom of the heat exchanger 312 from being immersed in condensate and improving the service life of the heat exchanger 312. The water guiding surface 161 is inclined towards the drain outlet 160 and has water guiding ribs 162. In this way, the water guiding ribs 162 can quickly guide the condensate flowing down from the heat exchanger 312 to the drain outlet 160, preventing water from accumulating in the water collection tank 150 and submerging the bottom of the heat exchanger 312.

[0061] Please refer to Figure 4 , Figure 5 and Figure 6 Furthermore, the first flange 111, the second flange 131, and the rear plate 158 are connected in sequence. The first flange 111 has a fourth flange 115 facing the air inlet side 171. The second flange 131 has a fifth flange 137 facing the air inlet side 171. The rear plate 158 of the water collection tank 150 has a sixth flange 163 facing the air inlet side 171, and the sixth flange 163 is inclined towards the top of the heat exchanger bracket 100. The fourth flange 115, the fifth flange 137, and the sixth flange 163 are connected in sequence.

[0062] In this embodiment, the first flange 111, the second flange 131, and the rear plate 158 are connected sequentially to form a closed structure, which improves the overall structural strength. The fourth flange 115, the fifth flange 137, and the sixth flange 163, connected sequentially to form a closed structure, improve structural stability and guide condensate. When hot air enters the heat exchanger mounting cavity 170 from the air inlet side 171 and undergoes heat exchange with the heat exchanger 312, condensate forms on the surface of the heat exchanger 312. Some of this condensate flows down along the fifth flange 137 on the air inlet side 171, providing initial guidance and preventing direct dripping. The sixth flange 163 is angled to guide the condensate flowing down the fifth flange 137 into the water collection tank 150, preventing condensate accumulation between the support and the heat exchanger 312, thereby improving the overall drainage efficiency and leak-proof performance.

[0063] Two snap-fit ​​areas 164 are provided at both ends of the front side of the water collection tank 150, which can snap copper pipes, etc. Connecting lugs 165 are provided on both sides of the water collection tank 150. The flange of the side panel 315 is provided with through holes corresponding to the positions of the connecting lugs 165. Screws can be driven into the connecting lugs 165 through the through holes to fix the bottom of the evaporator bracket to the outer shell.

[0064] Please refer to Figure 2 In this embodiment, sheet metal connectors 323 are connected to the middle of the heat exchanger 312 on both sides in the width direction, and the sheet metal connectors 323 are connected to the side panels 315 of the outer shell. An insulation cover 234 is also provided on the inner side of the front panel 316, below the air outlet.

[0065] In summary, this embodiment integrates the upper support 110, the two side supports 130, and the water collection tank 150 into a single structure. This integrated structure effectively enhances the overall strength and structural stability of the heat exchanger support 100. Compared to traditional split-type heat exchanger supports 100, it reduces the pre-assembly process, making assembly more convenient. The integrated heat exchanger support 100 also eliminates the need for screws to fix components, reducing assembly errors and the risk of loosening. Furthermore, the upper support 110, the two side supports 130, and the water collection tank 150 together form a heat exchanger mounting cavity 170. When the heat exchanger 312 is installed within the mounting cavity 170, the upper support 110 and the side supports 130 effectively support the top and sides of the heat exchanger 312, while the water collection tank 150 supports the bottom of the heat exchanger 312. This multi-point support method ensures that the heat exchanger 312 is evenly supported in all directions, further enhancing its stability during operation.

Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
