[0033] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0034] After research and analysis, it was found that the heat exchanger fixing structure in the related technology has the problem of large heat loss (when the heat exchanger is used as a condenser) / large cold loss (when the heat exchanger is used as an evaporator). The reason is that: the side plate and the fixed plate 3 are both sheet metal parts with good thermal conductivity. When the air conditioner is heating or cooling, the system refrigerant will transfer part of the heat or cold to the side plate through the heat exchanger body 1. Since the side plate and the fixed plate 3 fit each other in surface contact, the heat or cold will be quickly transferred to the fixed plate 3, and the fixed plate 3 is connected to the air conditioner casing 6 (also a sheet metal part) and in surface contact, the heat / cold will be further quickly transferred to the entire machine casing 6, resulting in a large heat loss / cold loss.

[0035] It can be understood that heat and cold are a set of relative concepts, and the heat conduction process can be described from different perspectives. Since heat is always transferred from a high temperature part to a low temperature part. Therefore, from the perspective of heat, the heat conduction process can be described as: a high temperature part transfers heat to a low temperature part. From the perspective of cold, the heat conduction process can be described as: a low temperature part transfers cold to a high temperature part. For example: when the heat exchanger is used as a condenser, the temperature is high, and the heat can be transferred to the casing 6 through the side plate and the fixed plate 3, resulting in heat loss in the condenser; when the heat exchanger is used as an evaporator, the temperature is low, and the cold can be transferred to the casing 6 through the side plate and the fixed plate 3 (this process is essentially that the casing 6 transfers heat to the heat exchanger body 1 through the fixed plate 3 and the side plate), resulting in cold loss in the evaporator.

[0036] To this end, the embodiment of the present application provides a heat exchanger fixing structure, including: a heat exchanger body 1, a first side plate 2 and a fixing plate 3, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 The first side plate 2 and the fixing plate 3 can be sheet metal parts, which are easy to process and shape, and have high strength, which is conducive to improving the fixing reliability of the heat exchanger.

[0037] The first side plate 2 is located at one side of the heat exchanger body 1 and is connected to the heat exchanger body 1. The first side plate 2 is provided with a first flange 21. Figure 3 and Figure 4 shown.

[0038] The fixing plate 3 may also be located on one side of the heat exchanger body 1 and connected to the first flange 21 , and a heat insulation structure is provided between the fixing plate 3 and the first flange 21 , and the heat insulation structure is configured to limit the first flange 21 from transferring heat to the fixing plate 3 .

[0039] The heat exchanger fixing structure provided in the embodiment of the present application is provided with a first flange 21 on the first side plate 2, and is connected to the fixing plate 3 by means of the first flange 21, which is beneficial to reducing the contact area between the first side plate 2 and the fixing plate 3; and a heat insulation structure is provided between the first flange 21 and the fixing plate 3, and the heat insulation structure can limit the first flange 21 from transferring heat to the fixing plate 3, thereby facilitating the reduction of the amount of heat / cold conducted to the fixing plate 3 through the first side plate 2, and further facilitating the reduction of the amount of heat / cold further conducted to the casing 6 of the air conditioner by the fixing plate 3, thereby achieving the purpose of reducing the heat loss / cold loss of the heat exchanger, and facilitating the improvement of the overall energy efficiency of the air conditioner.

[0040] In some exemplary embodiments, the heat exchanger fixing structure further includes: a second side plate 4 and a partition plate 5, such as Figure 1 As shown. The second side plate 4 is located on the other side of the heat exchanger body 1 and is connected to the heat exchanger body 1. The partition 5 is a plastic part, and the second side plate 4 is connected to the partition 5. The second side plate 4 can be a sheet metal part, which is easy to process and shape, and has high strength, which is conducive to improving the fixing reliability of the heat exchanger. The second side plate 4 can be located on the side of the heat exchanger body 1 where the refrigerant input and output pipes are located.

[0041] Compared with sheet metal parts, plastic parts have relatively poor thermal conductivity. Therefore, less heat is transferred between the first side plate 2 and the partition plate 5, which is beneficial to reducing the heat loss / cold loss of the heat exchanger body 1 and improving the energy efficiency of the whole machine.

[0042] The first side plate 2 and the second side plate 4 can be located on both sides of the length direction of the heat exchanger body 1, and the partition plate 5 can be located on one side of the thickness direction of the heat exchanger body 1. Figure 1 As shown, the first side plate 2 and the fixing plate 3 are located on the right side of the heat exchanger body 1, and the second side plate 4 is located on the left side of the heat exchanger body 1. Alternatively, the first side plate 2 and the fixing plate 3 are located on the left side of the heat exchanger body 1, and the second side plate 4 is located on the right side of the heat exchanger body 1. The partition plate 5 can be located on the rear side of the heat exchanger body 1.

[0043] like Figure 1 As shown, the partition 5 can be erected in the housing 6 of the air conditioner to divide the internal space of the housing 6 of the air conditioner into a heat exchange chamber and a fan chamber, and the heat exchanger body 1, the first side plate 2, the second side plate 4 and the fixed plate 3 can be located in the heat exchange chamber. The fan chamber can be provided with a motor, a wind wheel, a volute and other structures. The motor can drive the wind wheel to rotate and generate airflow. The partition 5 can be provided with a vent to ensure that the airflow can enter the heat exchange chamber to exchange heat with the heat exchanger body 1.

[0044] In some exemplary embodiments, Figure 5As shown, the heat insulation structure includes a heat insulation gap 215 and a protrusion located in the heat insulation gap 215. The protrusion is sandwiched between the fixing plate 3 and the first flange 21, so that the heat insulation gap 215 is formed between the fixing plate 3 and the first flange 21 (as shown in FIG. Figure 5 As shown), the first flange 21 is limited from transferring heat to the fixing plate 3.

[0045] The setting of the raised portion prevents the fixed plate 3 and the first flange 21 from forming a surface contact fitting relationship, but instead provides a heat insulating gap 215, which not only reduces the heat transfer area between the first flange 21 and the fixed plate 3, but also utilizes air with poor thermal conductivity to achieve a heat insulating effect, thereby reducing the heat conduction efficiency between the first flange 21 and the fixed plate 3, thereby reducing heat loss / cold loss.

[0046] Of course, the heat insulation structure is not limited to the structure of the heat insulation gap 215 and the protrusion. For example, the heat insulation structure may also include a heat insulation recess, which can also reduce the heat transfer area between the first flange 21 and the fixing plate 3, and can also use the air with poor thermal conductivity in the heat insulation recess to achieve a heat insulation effect. Alternatively, the heat insulation structure may also include a structure with heat insulation performance such as a heat insulation pad and a heat insulation layer.

[0047] In other embodiments, the first side plate 2 and the second side plate 4 may also be made of plastic side plates to reduce heat loss / cold loss. However, the structural strength of plastic parts is low. In order to ensure the reliability of fixing the heat exchanger body 1, the structure of the plastic side plate is more complicated, thicker and heavier, resulting in high processing costs and inconvenient assembly. In the aforementioned embodiment of the present application, the first side plate 2 and the second side plate 4 are both made of sheet metal parts, which are easy to process and low in cost, and are also conducive to reducing the weight of the whole machine, reducing the difficulty of assembly, and saving manpower and time costs.

[0048] In some exemplary embodiments, the raised portion includes a rib 211, such as Figure 5 , Figure 6 and Figure 8 As shown. The convex rib 211 facilitates the line contact matching between the first flange 21 and the fixing plate 3. Compared with the surface contact matching, the line contact matching has less heat loss / cold loss. The convex rib 211 can also act as a reinforcing rib, which is beneficial to improve the strength of the first flange 21. The convex rib 211 can be made by stamping.

[0049] Of course, the structure of the convex portion is not limited to the convex rib 211, and can also be a convex point, a convex hull (such as a hemispherical convex hull) and other structural forms, which facilitate the point contact matching of the first flange 21 and the fixing plate 3. Compared with the surface contact matching form, the point contact matching form has less heat loss / cooling loss.

[0050] In some exemplary embodiments, the cross-sectional profile of the rib 211 is arc-shaped, such as Figure 5 and Figure 6 The rib 211 is fixed to one of the first flange 21 and the fixing plate 3 and is tangent to the other of the first flange 21 and the fixing plate 3 , thereby achieving line contact between the first flange 21 and the fixing plate 3 .

[0051] Alternatively, the convex rib 211 may be provided on the first flange 21 and tangent to the fixed plate 3. Alternatively, the convex rib 211 may be provided on the fixed plate 3 and tangent to the first flange 21. Alternatively, both the first flange 21 and the fixed plate 3 may be provided with the convex rib 211, the convex rib 211 of the first flange 21 may be tangent to the fixed plate 3, and the convex rib 211 of the fixed plate 3 may be tangent to the first flange 21.

[0052] In some exemplary embodiments, the number of the ribs 211 is multiple, such as Figure 5 , Figure 6 and Figure 8 As shown, a plurality of ribs 211 are arranged at intervals along the length direction of the first flange 21. This facilitates maintaining a uniform insulation gap 215 between the first flange 21 and the fixing plate 3, and helps to prevent the first flange 21 and the fixing plate 3 from being close together due to local deformation.

[0053] The overall shape of the rib 211 is not limited, and can be a straight line, or a U-shaped, L-shaped structure. Figure 8 As shown, two ribs 211 are U-shaped, with the U-shaped opening facing away from the heat exchanger body 1 , and one rib 211 is L-shaped.

[0054] In some exemplary embodiments, the fixing plate 3 includes a fixing plate body 31 and a second flange 32 connected to the fixing plate body 31. Fig. 9 The fixing plate body 31 is connected to the first flange 21. The heat insulation structure is located between the fixing plate body 31 and the first flange 21, and the second flange 32 is configured to be connected to the housing 6 of the air conditioner.

[0055] The fixing plate body 31 can play a good supporting role for the heat exchanger body 1. The second flange 32 can be fixedly connected with the air conditioner casing 6 by welding, fasteners, etc., to ensure the position stability and use reliability of the fixing plate 3.

[0056] In some exemplary embodiments, the first flange 21 is parallel to the fixing plate body 31. Figure 5 and Figure 6 As shown, it is convenient for assembly and alignment.

[0057] In some exemplary embodiments, the first flange 21 is provided with a first connecting hole 212, such as Figure 3 , Figure 7 and Figure 8 The fixing plate 3 is provided with a second connection hole 311, as shown in FIG. Figure 3 and Fig. 9 As shown. The first connection hole 212 and the second connection hole 311 are fixedly connected by fasteners (such as screws). The fastener connection method has high connection strength and reliable fixation. The second connection hole 311 is provided in the fixing plate body 31.

[0058] In some exemplary embodiments, the number of the first connection holes 212 is multiple, such as Figure 7 and Figure 8 As shown, the second connection holes 311 can be arranged in one-to-one correspondence with the first connection holes 212, so as to connect the first flange 21 and the fixing plate 3 by multiple fasteners, effectively ensuring the fixing reliability of the fixing plate 3 to the heat exchanger body 1.

[0059] Part of the first connection holes 212 is configured as waist-shaped holes, such as Figure 7 and Figure 8 As shown, the other first connection holes 212 and the second connection holes 311 can be set as circular holes, which is convenient for reducing the difficulty of aligning the multiple first connection holes 212 with the multiple second connection holes 311. During the assembly process, the circular first connection holes 212 and the second connection holes 311 can be aligned first, the fasteners can be locked, and then the fasteners corresponding to the waist-shaped holes can be installed, which can effectively reduce the installation difficulties caused by the difficulty in aligning the holes, and is conducive to reducing the difficulty of assembling the subsequent fasteners.

[0060] In one embodiment, Figure 7 and Figure 8 As shown, there are two first connection holes 212 , one first connection hole 212 is a waist-shaped hole, and the other first connection hole 212 is a circular hole. The two first connection holes 212 are respectively located in the space surrounded by two U-shaped ribs 211 .

[0061] In some exemplary embodiments, the first flange 21 is provided with a limiting portion, and the fixing plate 3 is provided with a limiting matching portion, and the limiting portion and the limiting matching portion are limitedly matched to locate the relative position of the first flange 21 and the fixing plate 3.

[0062] In this way, the first flange 21 and the fixed plate 3 can first be pre-positioned through the limiting cooperation between the limiting part and the limiting cooperation part, so as to facilitate the concentric alignment of the first connecting hole 212 and the second connecting hole 311; and then fixedly connected by fasteners, so that the assembly process is simpler and more convenient, which is beneficial to improving assembly efficiency and saving labor costs and time costs.

[0063] In some exemplary embodiments, the limiting portion includes a limiting notch 213, such as Figure 7 and Figure 8 The limiting matching portion includes a limiting folding edge 312, as shown. Figure 3 , Figure 6 and Fig. 9 The limiting folding edge 312 is configured to be inserted into the limiting notch 213 and hook the first flange 21, as shown. Figure 6 As shown, the relative position of the first flange 21 and the fixing plate 3 is positioned. The limiting notch 213 can also reduce the heat dissipation area of ​​the first flange 21, thereby further reducing heat loss / cold loss. The limiting fold 312 can be provided on the fixing plate body 31.

[0064] Of course, the limiting portion is not limited to the limiting notch 213, and may be, for example, a limiting fold 312, a limiting groove, a limiting protrusion, a buckle, a buckle, etc. Correspondingly, the limiting matching portion is not limited to the limiting fold 312, and may be, for example, a limiting notch 213, a limiting protrusion, a limiting groove, a buckle, etc.

[0065] In some exemplary embodiments, the end of the limiting fold 312 is further provided with a guide fold 313, such as Figure 6 and Fig. 9 As shown, the guide fold 313 is configured to guide the limiting fold 312 to be inserted into the limiting notch 213, which is beneficial to further reduce the difficulty of assembling between the first flange 21 and the fixing plate 3, and is beneficial to further improve the assembly efficiency.

[0066] In some exemplary embodiments, the first flange 21 is provided with a heat dissipation notch 214, such as Figure 7 and Figure 8 As shown, this can further reduce the heat dissipation area of ​​the first flange 21, thereby further reducing the heat loss / cold loss of the heat exchanger body 1. In addition, this can also reduce the weight of the first side plate 2, which is conducive to reducing the weight of the whole machine. The shape and size of the heat dissipation gap 214 are not limited, as long as it does not affect the assembly requirements of the first flange 21 and the fixing plate 3.

[0067] like Figure 1 As shown, the embodiment of the present application further provides an air conditioner, comprising: a casing 6 and a heat exchanger fixing structure as in any one of the above embodiments, located in the casing 6. The fixing plate 3 is fixedly connected to the casing 6.
