Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to a heat exchanger mounting structure and an air conditioner. Background Technology

[0002] Heat exchangers in air conditioners are typically installed together with air ducts to allow more of the heat-exchanged air to flow into the ducts and outwards from the air conditioner, thus achieving better heat exchange. However, existing heat exchangers usually utilize side plates on both sides for installation with the air ducts. These two side plates often have different structural designs due to the arrangement of the heat exchange tubes and their installation with the air ducts. Because the outlines and structures of the two side plates are very similar, workers easily confuse them, leading to frequent misinstallation problems. Summary of the Invention

[0003] The main objective of this invention is to provide a heat exchanger installation structure that avoids the problem of misinstallation of the two side plates of the heat exchanger and improves the assembly efficiency of the heat exchanger.

[0004] To achieve the above objectives, the heat exchanger mounting structure proposed in this invention includes:

[0005] The heat exchanger includes a heat exchanger body and two side plates disposed on opposite sides of the heat exchanger body. Each side plate has a first flange folded in a first direction on the same side. The two first flanges are used to connect to the air duct of the air conditioner. The two side plates have the same structure.

[0006] Optionally, the side plate is further provided with a second flange that is arranged opposite to the first flange, and the heat exchanger body is located between the second flange and the first flange.

[0007] Optionally, the second flange is provided with a second mounting part, which is used to connect to the water receiving tray of the air conditioner.

[0008] Optionally, multiple second mounting portions are provided, and the multiple second mounting portions are distributed at intervals along the length direction of the side plate.

[0009] Optionally, the second mounting part is provided with a threaded bottom hole, and the heat exchanger mounting structure further includes a water receiving tray. The water receiving tray is provided with a positioning hole and an adjustment hole corresponding to the two threaded bottom holes. The adjustment hole and the positioning hole are distributed at intervals along the first direction.

[0010] Optionally, the side plate has a first pre-drilled area and a second pre-drilled area, the first pre-drilled area being used for mounting the heat exchanger body of the first model, and the first pre-drilled area and the second pre-drilled area being used together for mounting the heat exchanger body of the second model.

[0011] Optionally, the first pre-drilled area and the second pre-drilled area are arranged sequentially in the direction from the side plate toward the air duct.

[0012] Optionally, the heat exchanger body includes multiple heat exchange tubes, and the first pre-drilled area is provided with multiple pipe holes spaced apart along the width direction of the side plate. The pipe holes include multiple pipe mounting holes spaced apart along the length direction of the side plate, and the pipe mounting holes are used for the heat exchange tubes to be installed.

[0013] Optionally, the heat exchanger mounting structure further includes an air duct, the air duct including an air duct body and a sliding groove provided on the air duct body, the sliding groove being provided with two corresponding to the two first flanges; the first flanges are slidably inserted into the sliding grooves along a second direction, the second direction being intersecting the first direction.

[0014] The present invention also proposes an air conditioner including the aforementioned heat exchanger mounting structure.

[0015] The technical solution of this invention sets the first flanges of the two side plates to face the same direction, i.e., fold in the first direction, so that the two side plates have sufficient conditions to be set to have the same structure, that is, the two side plates are set as the same part. In this embodiment, the structures of the two side plates are set to be the same. In this way, after the workers receive the side plate part, they can arbitrarily install it on the left and right sides of the heat exchanger, that is, it can prevent incorrect installation and improve assembly efficiency; secondly, it can simplify the material management of the side plate part, thereby reducing material management costs; furthermore, since only a mold for one part is developed, the mold development cost can be reduced, thereby reducing the overall development cost of the air conditioner.

[0034] Heat exchangers in air conditioners are typically installed together with air ducts to allow more of the heat-exchanged air to flow into the ducts and outwards from the air conditioner, thus achieving better heat exchange. However, existing heat exchangers usually utilize side plates on both sides for installation with the air ducts. These two side plates often have different structural designs due to the arrangement of the heat exchange tubes and their installation with the air ducts. Because the outlines and structures of the two side plates are very similar, workers easily confuse them, leading to frequent misinstallation problems.

[0035] In view of this, the present invention proposes a heat exchanger mounting structure, referring to... Figures 1 to 4 ,in, Figure 2 The first direction refers to the direction from the right side of the heat exchanger to the left side in the figure; the second direction refers to the direction from the bottom side of the heat exchanger to the top side in the figure; and the third direction refers to the direction from the air duct towards the heat exchanger. In one embodiment of the present invention, the heat exchanger mounting structure includes:

[0036] The heat exchanger 20 includes a heat exchanger body 210 and two side plates 220 disposed on opposite sides of the heat exchanger body 210. Both side plates 220 have side edges close to the air duct 10 of the air conditioner. Both side edges of the side plates 220 are folded in a first direction with first flanges 221. The two first flanges 221 are used to connect with the air duct 10 of the air conditioner. The structures of the two side plates 220 are the same.

[0037] The technical solution of this invention sets the first flanges 221 of the two side plates 220 to face the same direction, i.e., folded in the first direction, so that the two side plates 220 have sufficient conditions to be set to have the same structure, that is, the two side plates 220 are set to be the same part. In this embodiment, the two side plates 220 are set to have the same structure. In this way, after the workers receive the side plate 220 part, they can arbitrarily install it on the left and right sides of the heat exchanger 20, that is, it can play a role in preventing incorrect installation and improving assembly efficiency; secondly, it can simplify the material management of the side plate 220 part, thereby reducing material management costs; furthermore, since only one part mold is developed, the mold development cost can be reduced, thereby reducing the overall development cost of the air conditioner. Of course, the two side plates 220 can also be set to have different structures, that is, the two side plates 220 are set to be two different parts. Regardless of whether the structures of the two side plates 220 are the same, the first folded edge 221 can strengthen the structural strength of the side plate 220, and the connection with the air duct 10 at this position with higher structural strength can improve the reliability of the installation of the heat exchanger 20 and the air duct 10.

[0038] Reference Figure 4 and 5 In this embodiment, the side plate 220 is further provided with a second flange 222 that is opposite to the first flange 221, and the heat exchanger body 210 is located between the second flange 222 and the first flange 221. The second flange 222 can also strengthen the structural strength of the side plate 220, thereby making the installation of the side plate 220 and the air duct 10 more reliable, and providing a more reliable installation effect for the heat exchanger body 210.

[0039] In this embodiment, optionally, the two side plates 220 include a first side plate and a second side plate arranged sequentially along a first direction. The heat exchanger tube includes a main pipe section and an elbow. The main pipe section has a welding end passing through the first side plate, and the elbow is welded to the welding end. Generally speaking, the heat exchanger tube 211 is usually made of copper or aluminum, and the corresponding heat exchangers are called copper tube heat exchangers and aluminum tube heat exchangers. The side plates of the aluminum tube heat exchanger are usually made of aluminum. In this way, the first flange 221 and the second flange 222 are both folded in a direction away from the welding end of the heat exchanger tube 211. For the aluminum tube heat exchanger, when welding the welding end of the heat exchanger tube and the elbow, the aluminum first flange 221 and the second flange 222 can be prevented from being melted and damaged by the high temperature of the welding gun or spatter. Understandably, this heat exchanger installation structure is also applicable to copper tube heat exchangers. That is, the side plate can be used in both copper tube heat exchanger and aluminum tube heat exchanger air conditioner products, thereby improving the adaptability of the side plate 220 and reducing the development cost of the air conditioner.

[0040] Reference Figure 1 ,2 In this embodiment, optionally, the second flange 222 is provided with a second mounting part 223, which is used to connect with the water receiving tray 30. In this way, by adding another mounting point to the heat exchanger body 210 through the second mounting part 223, and by mounting it with the water receiving tray 30, the installation reliability and stability of the heat exchanger body 210 can be further improved.

[0041] Reference Figure 1 , 2 In this embodiment, optionally, the second mounting part 223 is a threaded bottom hole. The heat exchanger mounting structure also includes a water receiving tray 30. The water receiving tray 30 is provided with a positioning hole 31 and an adjustment hole 32 corresponding to the two threaded bottom holes. The adjustment hole 32 and the positioning hole 31 are distributed at intervals along the first direction. It should be noted that the size of the positioning hole 31 is adapted to the threaded bottom hole, and the size of the adjustment hole 32 in the first direction is larger than the threaded bottom hole. This is so that when the side plate 220 and the water receiving tray 30 are fastened with screws, the adjustment hole 32 can effectively offset the influence of the manufacturing tolerance and assembly tolerance of the heat exchanger 20 and the manufacturing tolerance of the water receiving tray 30, which facilitates the installation by workers and improves the assembly efficiency. Secondly, the adjustment hole 32 can also make the water receiving tray 30 adaptable to different models of heat exchangers 20, which is conducive to the platform design of the water receiving tray 30 and thus reduces the product development cost of the air conditioner. Furthermore, the screw-locking fixing method simplifies the installation structure of the second mounting part 223 and the water tray 30, thereby reducing the manufacturing cost of the air conditioner. The screw connection is also simple and convenient, improving assembly efficiency. Specifically, the positioning hole 31 can be a round hole or a regular polygonal hole adapted to a threaded bottom hole, while the adjustment hole 32 can be a rectangular hole, an oblong hole, or an elliptical hole, with its major axis extending along the first direction. However, this design is not limited to this. In other embodiments, the second mounting part can also be a snap-fit ​​protrusion located on the side of the second flange away from the heat exchanger body, with the water tray having a snap-fit ​​hole corresponding to the snap-fit ​​protrusion, and the snap-fit ​​protrusion snapping into the snap-fit ​​hole.

[0042] Reference Figure 1 , 3 In this embodiment, optionally, multiple threaded bottom holes are provided, and the multiple threaded bottom holes are distributed at intervals along the second direction. In this way, at least one threaded bottom hole is provided as a reserved mounting hole, so that the side plate 220 parts with the same structure can be adapted to different models of heat exchanger body 210 or water receiving pan 30, which is conducive to the platform design of side plate 220 and thus reduces the overall development cost of air conditioner.

[0043] Reference Figure 5 and 6 ,in, Figure 5 This is a schematic diagram of the side plate 220 in this embodiment. Figure 6 for Figure 5The front view of the side plate 220 shows that, in this embodiment, the side plate 220 only has pipe mounting holes 226 in the first pre-drilled area 224, and can be adapted for installation with the first type of heat exchanger body 210. Optionally, in this embodiment, the side plate 220 has a first pre-drilled area 224 and a second pre-drilled area 225. The first pre-drilled area 224 is used for installation of the first type of heat exchanger body 210, and the first pre-drilled area 224 and the second pre-drilled area 225 are used together for installation of the second type of heat exchanger body 210. It should be noted that, referring to... Figure 2 The heat exchanger body 210 typically includes multiple heat exchange tubes 211; assuming the first type of heat exchanger body 210 has a smaller number of heat exchange tubes 211, while the second type of heat exchanger body has a larger number of heat exchange tubes. (Refer to...) Figure 7 and 8 , Figure 7 This is a schematic diagram of the structure of side plate 220' in another embodiment. Figure 8 for Figure 7 A front view of the middle side plate 220'. In another embodiment, the side plate 220' has pipe mounting holes 226 in the first pre-drilled area 224 and the second pre-drilled area 225, and can be adapted to be installed with the heat exchanger body of the second model. It can be understood that multiple pipe mounting holes 226 for heat exchange tubes 211 to pass through can be arranged in both the first pre-drilled area 224 and the second pre-drilled area 225, and the pipe mounting holes 226 corresponding to the heat exchange tubes 211 of the second model product are at least partially arranged with the same structure and the same installation position as the pipe mounting holes 226 corresponding to the heat exchange tubes 211 of the first model product. Understandably, if the side plate 220 only has pipe mounting holes 226 in the first pre-drilled area 224, then the first-type side plate 220 part can only be fitted to the first-type heat exchanger body 210. If the side plate 220 has pipe mounting holes 226 in both the first pre-drilled area 224 and the second pre-drilled area 225, then the second-type side plate 220 part can be fitted to both the first-type and second-type heat exchanger bodies 210. Understandably, if the second-type side plate 220 part is directly installed with the first-type heat exchanger body 210, the pipe mounting holes 226 in the second pre-drilled area 225 will be idle, which will arouse suspicion from users. For example, users may think that the manufacturer has secretly reduced the configuration, thus causing user complaints. Therefore, in order to avoid user complaints, different models of side plate 220 parts are required for different models of heat exchangers 20. Under this premise, the pipe mounting holes 226 on the first pre-drilled area 224 are set to be shared by different models of heat exchangers 20, so that the molding molds of the side plate 220 and the pipe mounting holes 226 on it can be shared at least partially, thereby reducing the mold development cost and the overall development cost of the air conditioner.

[0044] Reference Figure 2 , 5 In this embodiment, the heat exchanger body 210 further includes multiple heat exchange tubes 211. The first pre-drilled area 224 is provided with multiple pipe holes spaced apart along the width direction of the side plate 220. These pipe holes include multiple pipe mounting holes 226 spaced apart along the length direction of the side plate 220. The pipe mounting holes 226 are used for the heat exchange tubes 211 to pass through and be installed. It should be noted that "multiple" refers to two or more. Thus, the multiple pipe mounting holes 226 on the first pre-drilled area 224 are arranged in an orderly manner, which not only helps to improve the heat exchange efficiency of the heat exchanger body 210 but also simplifies the mold structure of the side plate 220, thereby reducing mold development costs.

[0045] Reference Figure 7 and 8 In this embodiment, the second pre-drilled area 225 is further provided with at least one pipe routing hole, which includes a plurality of pipe mounting holes 226 spaced apart along the length of the side plate 220. Thus, the plurality of pipe mounting holes 226 on the second pre-drilled area 225 are arranged in an orderly manner, which not only helps to improve the heat exchange efficiency of the heat exchanger body 210, but also simplifies the mold structure of the side plate 220, thereby reducing mold development costs.

[0046] In this embodiment, optionally, the pipe mounting holes 226 on the side plate 220 are formed using a stamping process. This allows the pipe mounting holes 226 on the first pre-drilled area 224 and the second pre-drilled area 225 to be formed in two separate stamping processes. The pipe mounting holes 226 on the second pre-drilled area 225 can be selectively formed according to product requirements, enabling side plate 220 parts with different structures to share some forming molds, thereby reducing mold development costs and ultimately reducing the overall development cost of the air conditioner. Specifically, the side plate 220 can be formed into a first flange 221 and a second flange 222 using a stamping, drawing, or extrusion molding process. Then, the side plate 220 is sent to the first punching process, where a pipe mounting hole 226 is punched out on the first pre-drilled area 224 using a first punching die, directly obtaining a first-model side plate 220 part that can be fitted to the first-model heat exchanger body 210. To obtain a second-model side plate 220' part that can be fitted to the second-model heat exchanger body, the first-model side plate 220 part can be sent to the second punching process, where a second punching die is used to punch out the pipe mounting hole 226 on the second pre-drilled area 225. In this way, the first-model side plate 220 and the second-model side plate 220' at least share a drawing or extrusion molding die and a first punching die, thereby reducing mold development costs and ultimately reducing the overall development cost of the air conditioner. However, this design is not limited to this. In other embodiments, the side plate can also be set by injection molding, wherein the injection mold master mold of the two side plate parts of the first model and the second signal can be completely shared, while the injection mold male mold can be partially shared.

[0047] Reference Figure 6 and 8 In this embodiment, optionally, the first pre-drilled area 224 and the second pre-drilled area 225 are arranged sequentially in the direction from the side plate 220 toward the air duct 10. Generally speaking, the air duct 10 is usually built into the air conditioner, so the side of the heat exchanger body 210 near the air duct 10 is concealed inside the air conditioner, while the side away from the air duct 10 is visible to the user. By placing the second pre-drilled area 225 near the air duct 10, the second pre-drilled area 225 can be concealed, that is, the heat exchanger 20 appears the same from the outside when viewed from different models of air conditioners. For example, as... Figure 4 As shown, the side of the first-type heat exchanger body 210 away from the air duct 10 is nearly flush with the end face of the second flange 222, and the side of the second-type heat exchanger body away from the air duct can also achieve this state. However, this design is not limited to this; in other embodiments, the second pre-drilled area can also be located within the first pre-drilled area.

[0048] Reference Figures 9 to 11In this embodiment, optionally, the heat exchanger mounting structure further includes a duct 10. The duct 10 includes a duct body 11 and a sliding groove 12 provided on the side edge of the duct body 11. The sliding groove 12 is provided with two corresponding first flanges 221. The first flanges 221 slide into the sliding grooves 12 along a second direction, which intersects with the first direction. It should be noted that the second direction refers to the length direction of the side plate 220, and the first direction is the thickness direction of the side plate 220. This simplifies the mounting structure of the heat exchanger 20 and the duct 10, thereby reducing manufacturing costs. Furthermore, the installation operation of sliding the first flanges 221 into the sliding grooves 12 is simple, thereby improving assembly efficiency. However, this design is not limited to this. In other embodiments, the heat exchanger mounting structure may also include a duct, which includes a duct body and a snap-fit ​​protrusion provided on the side edge of the duct body. The first flange is provided with a snap-fit ​​hole corresponding to the snap-fit ​​protrusion, and the snap-fit ​​protrusion is snapped into the snap-fit ​​hole.

[0049] Reference Figure 10 and 11 In this embodiment, optionally, a third flange 111 extends along the first direction from the side edge of the duct body 11, and a fourth flange 112 extends along the direction toward the heat exchanger body 210 from the third flange 111. A first limiting portion 113 protrudes from the fourth flange 112 in the direction away from the first direction. The third flange 111, the fourth flange 112, and the first limiting portion 113 together define the slide groove 12. Thus, the third flange 111 and the fourth flange 112 not only strengthen the structural strength of the side edge of the duct body 11, but also cooperate with the first limiting portion 113 to limit the first flange 221 within the slide groove 12. This slide groove 12 forming structure is not only simple in structure, thus helping to reduce the manufacturing cost of the duct 10, but also has good structural strength, thereby improving the installation stability and reliability of the duct 10 and the heat exchanger 20. However, this design is not limited to this. In other embodiments, the side edge of the air duct body may be provided with a groove on the end face facing the heat exchanger body. The groove has a first end and a second end distributed sequentially in a second direction. The groove edge of the second end protrudes towards the center of the groove and a limiting protrusion abuts against the side of the first flange away from the air duct body.

[0050] Reference Figure 10 In this embodiment, optionally, the first limiting portion 113 has a first side edge and a second side edge sequentially distributed in a second direction. The side of the first limiting portion 113 facing the third flange 111 includes a first guide surface segment 114 near the first side edge. In the second direction, the first guide surface segment 114 extends obliquely in a direction close to the fourth flange 112. Thus, the first guide surface segment 114 can play a good guiding role, thereby facilitating the worker to operate the first flange 221 to slide and insert it into the groove 12 in the second direction.

[0051] Reference Figure 9 and 10 In this embodiment, optionally, the third flange 111 is provided with an avoidance groove 115 corresponding to the first limiting part 113. Generally speaking, the air duct 10, due to its complex structure and high structural strength requirements, is usually manufactured using injection molding. Understandably, the smaller the width of the groove 12 in the direction from the side plate 220 towards the air duct 10, the better it is at limiting the displacement of the side plate 220 in that direction, thereby reducing the amount of swaying of the side plate 220 in that direction and making the installation of the side plate 220 and the air duct 10 more stable and reliable. Since the thickness of the first flange 221 in that direction is usually small enough to meet the installation strength requirements, the width of the groove 12 is also set to be small. However, if the distance between the third flange 111 and the first limiting part 113 is too small, the corresponding mold structure will be too thin, leading to problems with the mold structure and a short service life. Therefore, by partially sinking the area of ​​the third flange 111 corresponding to the first limiting part 113, that is, by setting up a structure to avoid the sink groove 115, the mold structure corresponding to that location can be thickened, thereby reducing the probability of mold errors and increasing the service life of the mold.

[0052] In this embodiment, optionally, the third flange 111 is recessed with a stepped portion corresponding to the first limiting portion 113, and the clearance groove 115 is located on the bottom wall of the stepped portion. Thus, by providing the stepped portion, not only can the mold structure corresponding to the clearance groove 115 be strengthened, but the structural strength of the third flange 111 itself can also be strengthened, thereby improving the structural strength of the slide groove 12, and further improving the stability and reliability of the installation of the heat exchanger 20 and the air duct 10.

[0053] Reference Figure 9 and 10 In this embodiment, optionally, a supporting portion 116 protrudes from the center of the bottom of the recess 115 toward the first limiting portion 113, and the side of the first flange 221 facing the recess 115 abuts against the supporting portion 116. Thus, while improving the structural strength of the mold, the supporting portion 116 and the first limiting portion 113 together limit the first flange 221, thereby improving the limiting effect of the slide 12 on the first flange 221 and reducing the probability of looseness and wobbling after the side plate 220 is installed.

[0054] Reference Figure 10 and 11In this embodiment, optionally, the peripheral surface of the abutment portion 116 is arc-shaped. This allows the abutment portion 116 to provide good guidance, facilitating the worker's operation of sliding the first flange 221 along the second direction past the avoidance groove 115 and inserting it deeper. However, this design is not limited to this. In other embodiments, the abutment portion may have a fifth side edge and a sixth side edge sequentially distributed in the second direction, and the side of the abutment portion facing the first limiting portion includes a third guide surface segment near the fifth side edge. In the second direction, the third guide surface segment extends obliquely towards the first limiting portion.

[0055] In this embodiment, optionally, the supporting portion 116 protrudes from the bottom surface of the groove of the third flange 111. In this way, the supporting portion 116, together with the first limiting portion 113, can better confine the first flange 221 of the side plate 220 within the slide groove 12, further reducing the probability of looseness and wobbling after the side plate 220 is installed, thereby improving the stability and reliability of the installation of the heat exchanger 20 and the air duct 10.

[0056] Reference Figure 10 and 11 In this embodiment, optionally, multiple first limiting portions 113 are provided, and the multiple first limiting portions 113 are distributed at intervals along the second direction. In this way, the first flange 221 can be better confined within the slide groove 12, reducing the probability of looseness and wobbling after the side plate 220 is installed, thereby improving the stability of the installation of the heat exchanger 20 and the air duct 10.

[0057] Reference Figure 9 , 10 In this embodiment, optionally, the two sliding grooves 12 include a first sliding groove 12 and a second sliding groove 12 arranged sequentially along a first direction. A third flange 111 on the first sliding groove 12 protrudes towards the heat exchanger body 210 with a second limiting portion 117. The side of the second limiting portion 117 facing the first sliding groove 12 abuts against the side plate 220. Thus, by using the second limiting portion 117 abutting against the side plate 220, the side plate 220 can be prevented from sliding out of the first sliding groove 12 in a direction opposite to the first direction, thereby improving the reliability and stability of the installation of the heat exchanger 20 and the air duct 10. It can be understood that since both side plates 220 are fixed relative to the heat exchanger body 210, limiting only one side plate 220 to prevent it from sliding out in a direction opposite to the first direction ensures a good connection between the other side plate 220 and the heat exchanger body 210 and the air duct 10. This simplifies the installation structure of the air duct 10, thereby reducing its manufacturing cost. However, this design is not limited to this. In other embodiments, the third flanges on both the first and second slides may be provided with second limiting portions, with the side of the second limiting portion facing the fourth flange abutting against the side plate.

[0058] Reference Figure 10 and11 In this embodiment, optionally, the second limiting portion 117 has a third side edge and a fourth side edge sequentially distributed in the second direction. The side of the second limiting portion 117 facing the fourth flange 112 includes a second guide surface segment 118 near the first side edge. In the second direction, the second guide surface segment 118 extends obliquely in the direction close to the fourth flange 112. Thus, the second guide surface segment 118 can play a good guiding role, thereby facilitating the worker to operate the first flange 221 to slide and insert it into the groove 12 in the second direction.

[0059] Reference Figure 10 and 11 In this embodiment, optionally, the second limiting part 117 and the first limiting part 113 are arranged in a staggered manner in the second direction. This simplifies the molding die structure of the air duct 10, thereby reducing the mold development cost of the air duct 10.

[0060] Reference Figure 10 and 11 In this embodiment, optionally, multiple second limiting portions 117 are provided, and the multiple second limiting portions 117 are distributed at intervals along the second direction. This can better confine the first flange 221 within the slide groove 12, reduce the probability of the side plate 220 accidentally slipping out of the slide groove 12 after installation, and thus improve the stability of the installation of the heat exchanger 20 and the air duct 10.
