[0057] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0058] An expansion valve and a heat exchange assembly for heat exchange with air are provided in the air conditioner, and the expansion valve is fixed to the heat exchange assembly through pipes connected at both ends. Since the weight of the expansion valve is heavier than the pipe body connected to it, the expansion valve will shake up and down during the transportation of the air conditioner. When the length of the pipe body connected to the expansion valve is long, or the bump amplitude during the transportation of the air conditioner is large, the shaking of the expansion valve will cause the pipe body connected to it to deform. In the related art, in order to prevent the pipe body connected to the expansion valve from deforming, a solution is provided in which the pipe body connected to the expansion valve is bent to form a buffer zone. By providing the buffer zone, the elastic deformation of the pipe body connected to the expansion valve is increased, thereby preventing the pipe body connected to the expansion valve from generating inelastic deformation. However, in the above scheme, on the one hand, the pipe body connected to the expansion valve needs to be bent, and the processing cost is high; on the other hand, the processing error and assembly error of the bent pipe body are large, and internal stress is easily generated after installation; on the other hand, the bent pipe body can generally only adapt to the vibration generated during the normal operation of the air conditioner, but may not be able to adapt to the severe bumps generated during the transportation of the air conditioner, so that the pipe body connected to the expansion valve may still be inelasticly deformed. In another solution, a bracket is provided to fix the expansion valve, wherein one end of the bracket is connected to the expansion valve and the other end is connected to the housing of the air conditioner. However, in this solution, although the expansion valve can be prevented from violently shaking, the fixing bracket must be installed after the heat exchange component and the expansion valve are installed, which limits the installation process.

[0059] In view of this, see Figures 1 to 15 In some embodiments of the present application, a fixed bracket 100 is provided. The fixed bracket 100 is used for an air conditioner. The air conditioner includes a heat exchange component 200 and an expansion valve 300. One side of the expansion valve 300 is connected to the first tube body 230, and the other side is connected to the second tube body 240. One side of the fixed bracket 100 is suitable for being connected to the heat exchange component 200, and the other side is used to directly or indirectly support the expansion valve 300 (the fixed bracket 100 indirectly supports the expansion valve 300 by supporting the first tube body 230 and / or the second tube body 240), so as to reduce the shaking amplitude of the expansion valve 300 during transportation.

[0060] See also Figure 7-Figure 8The heat exchange assembly 200 may include a heat exchange body 210 and an outer plate 220 connected to the outer periphery of the heat exchange body 210. The heat exchange body 210 may specifically include a heat exchange pipeline and heat exchange fins connected to the heat exchange pipeline. The heat exchange fins are arranged at intervals, and the heat exchange pipeline passes through each heat exchange fin. The heat exchange pipeline is used to circulate a heat exchange medium, the heat exchange medium and the heat exchange pipeline perform heat exchange, the heat exchange pipeline and the heat exchange fins perform heat exchange, and the heat exchange fins and the air perform heat exchange, thereby ultimately achieving heat exchange between the heat exchange medium and the air. An outer plate 220 is provided on the periphery of the heat exchange body 210. On the one hand, the outer plate 220 can make the structure of the heat exchange body 210 more stable. On the other hand, the outer plate 220 can also be used to connect multiple heat exchange bodies 210. In some embodiments, the heat exchange assembly 200 includes two heat exchange bodies 210, one end of the two heat exchange bodies 210 are close to and connected to each other, and the other end is far away from each other, so that the two heat exchange bodies 210 are arranged in a V shape, and the outer plate 220 is arranged on the outer periphery of the two heat exchange bodies 210, and connects the two heat exchange bodies 210 into an integrated structure.

[0061] See also Figure 1-Figure 4 The fixing bracket 100 includes a fixing portion 110 and a supporting portion 130. The fixing portion 110 is suitable for fixing to the heat exchange component 200. The fixing portion 110 can be fixed to the heat exchange component 200 in a variety of ways. For example, in some embodiments, the fixing portion 110 can be fixed to the heat exchange component 200 by welding, gluing, or interference connection. In other embodiments, the fixing portion 110 can be connected to the heat exchange component 200 in a detachable manner such as threaded connection or clamping. See Figure 6-Figure 9 In this embodiment, the fixing part 110 is threadedly connected to the heat exchange assembly 200. Specifically, the fixing part 110 is provided with a threaded through hole, the heat exchange assembly 200 is provided with a threaded hole, and the fixing part 110 and the heat exchange assembly 200 are threadedly connected by bolts or screws.

[0062] The fixing portion 110 can be connected to any suitable fixing position of the heat exchange component 200. In some embodiments, the fixing portion 110 can be fixed to the heat exchange pipeline of the heat exchange component 200. For example, the fixing portion 110 includes a plurality of hooks, and the plurality of hooks extend into the plurality of gaps of each heat exchange fin one by one so as to be hung on the heat exchange pipeline. In this embodiment, preferably, the heat exchange component 200 can be made of a heat insulating material to reduce the heat on the heat exchange pipeline from being transferred to the expansion valve 300. In other embodiments, the fixing portion 110 can be fixed to the heat exchange fin. For example, the fixing portion 110 includes a plurality of spaced connection plates, each of which is correspondingly inserted between two heat exchange fins and welded, glued or riveted to one of the heat exchange fins. Since the structural strength of the fins is not high, in order to improve the connection stability of the fixing bracket 100, a plurality of connection plates can be provided to connect the plurality of fins, thereby improving the force limit of the fixing bracket 100. See. Figure 4 as well as Figure 6-Figure 11 In this embodiment, the fixing part 110 is fixed to the outer plate 220 of the heat exchange assembly 200. Specifically, the outer plate 220 may include an upper plate body 221 located at the top, a lower plate body located at the bottom, and a side plate body 222 located between the upper plate body 221 and the lower plate body. The fixing part 110 may be fixed to any plate body in the outer plate 220. The specific fixing position of the fixing part 110 depends on the specific arrangement position of the expansion valve 300. When the expansion valve 300 is arranged at a position closer to the top of the heat exchange assembly 200, the fixing part 110 may be fixed to the upper plate body 221; when the expansion valve 300 is arranged at a position closer to the bottom, the fixing part 110 may be fixed to the lower plate body; when the expansion valve 300 is arranged at a position closer to the lateral side, the fixing part 110 may be fixed to the side plate body 222. When the fixing portion 110 is fixed to the outer plate 220 of the heat exchange assembly 200, on the one hand, since the outer plate 220 is located on the outside, the assembly of the fixing bracket 100 is not easily interfered with by other components of the heat exchange assembly 200, thereby improving the assembly convenience of the fixing bracket 100; on the other hand, the structural strength of the outer plate 220 is higher, and when the air conditioner is shaken to a large extent during transportation, the outer plate 220 can withstand a stronger impact force from the expansion valve 300.

[0063] The supporting portion 130 may be directly connected to the fixing portion 110, or may be indirectly connected to the fixing portion 110 via the intermediate connecting plate 120. The supporting portion 130 is suitable for supporting at least one of the expansion valve 300, the first tube body 230, and the second tube body 240. Figure 1-Figure 6 The number of supporting structures of the supporting portion 130 depends on actual needs. When the supporting portion 130 has one supporting structure, the supporting portion 130 supports any one of the expansion valve 300, the first tube body 230 and the second tube body 240; see Figure 3-Figure 6When the supporting portion 130 has two supporting structures, the supporting portion 130 can support any two of the expansion valve 300, the first tube body 230 and the second tube body 240; when the supporting portion 130 has three supporting structures, the three supporting structures of the supporting portion 130 can support the expansion valve 300, the first tube body 230 and the second tube body 240 one by one. The supporting portion 130 is used to support the bottom of the expansion valve 300, the first tube body 230 and the second tube body 240, so that the expansion valve 300 is not easy to shake up and down during the transportation of the air conditioner, and the probability of deformation of the first tube body 230 and the second tube body 240 is effectively reduced. In addition, compared with the design in the related art that increases the elastic deformation of the first tube body and the second tube body by bending the first tube body and the second tube body, the processing difficulty of the first tube body and the second tube body in the related art is large, and the processing error and assembly error are large. Since the present solution limits the up and down displacement of the expansion valve 300, the elastic deformation requirements of the first tube body 230 and the second tube body 240 are reduced. Therefore, the first tube body 230 and the second tube body 240 do not need to be bent, which can reduce the processing difficulty of the first tube body 230 and the second tube body 240, and can also reduce the assembly error of the expansion valve 300. In addition, in the present solution, the fixing portion 110 of the fixing bracket 100 is suitable for connecting to the heat exchange component 200, so that the heat exchange component 200, the fixing bracket 100 and the expansion valve 300 can form a whole, which facilitates the assembly and maintenance of the whole parts. Compared with the structure in which the fixing portion 110 of the fixing bracket 100 is connected to the inner wall of the shell of the air conditioner, the fixing bracket can only be installed after the expansion valve and the heat exchange unit are installed in the shell in the related art, while the fixing bracket 100 in the present solution can be installed before the heat exchange component 200 is assembled into the shell, and the assembly process is more flexible.

[0064] It should be noted that the fixed bracket 100 in the present application can always maintain a supporting state under the normal state of the air conditioner; it can also not maintain a supporting state under the normal state of the air conditioner, and a short supporting state will occur during the process of bumping and the downward swinging of the expansion valve 300 during transportation. Specifically, in some embodiments, after the fixed bracket 100, the expansion valve 300 and the heat exchange assembly 200 are assembled, the supporting portion 130 of the fixed bracket 100 abuts against the lower end of at least one of the expansion valve 300, the first tube body 230 and the second tube body 240 (it should be noted that the directional terms such as "upper" and "lower" in this article are all based on the directional position of the air conditioner in the working state) to support the expansion valve 300, thereby preventing the expansion valve 300 from swinging up and down significantly when bumping occurs during the transportation of the air conditioner. In another embodiment, after the fixed bracket 100, the expansion valve 300 and the heat exchange component 200 are assembled, the supporting portion 130 is located at the lower end of at least one of the expansion valve 300, the first tube body 230 and the second tube body 240 and is spaced apart from each other, so that the supporting portion 130 is not connected to any one of the expansion valve 300, the first tube body 230 and the second tube body 240 under normal conditions of the air conditioner. However, when a large bump occurs during the transportation of the air conditioner, the expansion valve 300 can swing downward until it is briefly supported by the supporting portion 130, so that the supporting portion 130 can limit the downward swinging limit of the expansion valve 300, thereby preventing the expansion valve 300 from swinging too much and causing deformation of the first tube body 230 and / or the second tube body 240. In this solution, compared with the structure in which the supporting portion 130 supports the expansion valve 300 at all times under normal circumstances, it is possible to compensate for the assembly error of the expansion valve 300. When the actual position of the expansion valve 300 after assembly is higher or lower than the designed position (since the expansion valve 300 is mainly suspended and fixed by the first tube body 230 and the second tube body 240, there may be a large assembly error), the supporting portion 130 can still achieve good support, and there will be no problem that the supporting portion 130 cannot achieve the supporting function when the actual position of the expansion valve 300 after assembly is lower than the designed position and lower than the supporting portion 130.

[0065] See also Figure 6-Figure 11In some embodiments, the expansion valve 300 includes a first joint 310 connected to the first tube body 230 and a second joint 320 connected to the second tube body 240. In this embodiment, the first joint 310 and the second joint 320 are located on opposite sides of the expansion valve 300 in the transverse direction. Considering that the supporting effect is better when the supporting portion 130 supports both sides of the expansion valve 300, in this embodiment, the supporting portion 130 includes two supporting structures, and the two supporting structures respectively support the opposite sides of the expansion valve 300 in the transverse direction. Specifically, the supporting portion 130 includes a first supporting arm 135 and a second supporting arm 136, the first supporting arm 135 is suitable for supporting the first joint 310 and / or the first tube body 230, and the second supporting arm 136 is suitable for supporting the second joint 320 and / or the second tube body 240. When the first supporting arm 135 supports the first joint 310 and the first tube body 230 at the same time, the first supporting arm 135 supports the junction of the first joint 310 and the first tube body 230; similarly, when the second supporting arm 136 supports the second joint 320 and the second tube body 240 at the same time, the second supporting arm 136 supports the junction of the second joint 320 and the second tube body 240.

[0066] See also Fig. 9 as well as Fig.11 In some embodiments, the first supporting arm 135 supports the first tube body 230, and the second supporting arm 136 supports the second tube body 240, so that the fixed bracket 100 indirectly supports the expansion valve 300. Compared with the structure in which the fixed bracket 100 directly supports the expansion valve 300, in this embodiment, the fixed bracket 100 only needs to correspond to the relative position and size of the first tube body 230 and the second tube body 240. Therefore, when the external dimensions and type of the expansion valve 300 change, the fixed bracket 100 can still support the expansion valve 300 well by supporting the first tube body 230 and the second tube body 240, that is, at this time, the fixed bracket 100 can adapt to more types of expansion valves 300.

[0067] When the fixing portion 110 of the fixing bracket 100 is connected to the outer plate 220 of the heat exchange assembly 200, see Figure 4 as well as Figure 7-Figure 11 In some embodiments, the fixing bracket 100 can be adapted to be connected to the upper plate body 221 of the outer plate 220 (the plate body on which the outer plate 220 is located when the heat exchange assembly 200 is in working state). Specifically, the fixing bracket 100 also includes a connecting plate body 120, and the connecting plate body 120 is respectively connected to the fixing portion 110 and the supporting portion 130. The fixing portion 110 is connected to the upper side of the connecting plate body 120, so that the fixing portion 110 is adapted to be fixed to the upper plate body 221. In order to facilitate supporting the expansion valve 300, see Fig. 9 as well as Fig.11In some embodiments, when the fixing portion 110 is connected to the upper side of the connecting plate body 120, the supporting portion 130 can be connected to the side of the connecting plate body 120 along the lateral direction and extend toward the expansion valve 300. When the fixing bracket 100 has a first supporting arm 135 and a second supporting arm 136, the two supporting arms can be correspondingly connected to the two lateral sides of the connecting plate body 120, so that the first supporting arm 135 supports the first tube body 230 and the second supporting arm 136 supports the second tube body 240. Figure 3 In other embodiments, the supporting portion 130 may also be connected to the lower side of the connecting plate body 120 and extend toward the expansion valve 300. Specifically, when the fixing bracket 100 includes a first supporting arm 135 and a second supporting arm 136, the first supporting arm 135 and the second supporting arm 136 may be respectively connected to both sides of the lower side of the connecting plate body 120, so that the first supporting arm 135 supports the first tube body 230 and the second supporting arm 136 supports the second tube body 240.

[0068] When the fixing portion 110 of the fixing bracket 100 is connected to the outer plate 220 of the heat exchange assembly 200, see Figure 12-Figure 15 In some embodiments, the fixing bracket 100 can be suitable for connecting to the side plate body 222 along the lateral side of the outer plate 220 (the plate body of the outer plate 220 located on the lateral side when the heat exchange assembly 200 is in the working state). Specifically, the fixing bracket 100 also includes a connecting plate body 120, and the connecting plate body 120 is respectively connected to the fixing portion 110 and the supporting portion 130. The fixing portion 110 is connected to one side of the connecting plate body 120 along the lateral side, so that the fixing portion 110 is suitable for connecting to the side plate body 222. In order to facilitate the support of the expansion valve 300, see Figure 14-15 In some embodiments, the supporting portion 130 is connected to the other side of the connecting plate body 120 in the transverse direction (the side opposite to the fixing portion 110), and extends in the direction close to the expansion valve 300. In this embodiment, the supporting portion 130 includes only one supporting arm. In other embodiments, the supporting portion 130 can also be connected to the lower side of the connecting plate body 120, and the supporting portion 130 includes a first supporting arm 135 and a second supporting arm 136, and the first supporting arm 135 and the second supporting arm 136 are respectively connected to the two sides of the lower side plate of the connecting plate body 120 in the transverse direction, so that the first supporting arm 135 supports the first tube body 230 and the second supporting arm 136 supports the second tube body 240.

[0069] In other embodiments, when the outer plate 220 further includes a lower plate body, the fixing portion 110 may also be connected to the lower side of the connecting plate body 120, so that the fixing portion 110 is suitable for connecting to the lower plate body of the outer plate 220. In this case, the supporting portion 130 may be connected to the upper side of the connecting plate body 120 to support the expansion valve 300, or may be connected to the side of the connecting plate body 120 along the lateral direction to support the expansion valve 300. When the supporting portion 130 includes two supporting arms, in one embodiment, the two supporting arms may be respectively connected to the two sides of the connecting plate body 120 along the lateral direction, or the two supporting arms may also be respectively connected to the two sides of the upper side of the connecting plate body 120 along the lateral direction.

[0070] Considering that there may be a distance between the expansion valve 300 and the outer plate 220, when the fixing bracket 100 is connected to the outer plate 220, in order to facilitate the fixing bracket 100 to support the expansion valve 300, the fixing bracket 100 may be provided with a bending portion extending toward the expansion valve 300, thereby compensating for the distance between the expansion valve 300 and the outer plate 220. Figure 4-Figure 6 In some embodiments, the connecting plate body 120 includes a plate body 121 and a first bent portion 122 connected to one side of the plate body 121, the first bent portion 122 is bent in a direction away from the expansion valve 300, and the first bent portion 122 is connected to the fixing portion 110 on the side away from the plate body 121. In this solution, on the one hand, the setting of the first bent portion 122 can compensate for the distance between the expansion valve 300 and the outer plate 220, so that it is convenient for the supporting portion 130 to support the expansion valve 300; on the other hand, the setting of the first bent portion 122 can also make a certain distance between the connecting plate body 120 and the heat exchange body 210, thereby reducing the heat exchange amount between the heat exchange body 210 and the connecting plate body 120, and further reducing the heat exchange amount between the expansion valve 300 and the heat exchange body 210.

[0071] In order to compensate for the distance between the expansion valve 300 and the outer plate 220, see Figure 6 as well as Fig.15In some embodiments, the connecting plate body 120 includes a plate body 121 and a second bent portion 123 connected to one side of the plate body 121. The second bent portion 123 is bent toward the expansion valve 300, and the side of the second bent portion 123 away from the plate body 121 is connected to the supporting portion 130. In this solution, on the one hand, the second bent portion 123 can compensate for the distance between the expansion valve 300 and the outer plate 220, so that the supporting portion 130 can support the expansion valve 300; on the other hand, the structural setting of the second bent portion 123 can also increase the maximum force of the supporting portion 130, thereby improving the anti-bumping effect of the heat exchange unit 10. In some embodiments, the connecting plate body 120 of the fixing bracket 100 may also be provided with both a first bending portion 122 and a second bending portion 123, so that the first bending portion 122 and the second bending portion 123 jointly compensate for the distance between the expansion valve 300 and the outer plate 220, while reducing the extension of the first bending portion 122 and the second bending portion 123. In addition, the connecting side plate has two parts bent in different directions, which also improves the overall bending resistance of the connecting side plate, making it less likely to deform.

[0072] Due to the irregular structure of the expansion valve 300, some parts of it are close to the heat exchange assembly 200, while some parts are far away from the heat exchange assembly 200. This makes the supporting effect poor when the supporting part 130 supports the expansion valve 300 close to the heat exchange assembly 200. When the supporting part 130 supports the expansion valve 300 far away from the heat exchange assembly 200, the connecting plate body 120 is prone to positional interference with the expansion valve 300. In view of this, see Figure 4-Figure 6 ,as well as Fig.15 In some embodiments, the connecting plate body 120 is provided with an avoidance hole 124, which is suitable for avoiding the expansion valve 300. The portion of the expansion valve 300 close to the heat exchange assembly 200 can pass through the avoidance hole 124 of the connecting plate body 120, thereby avoiding position interference with the connecting plate body 120, and the supporting portion 130 can also more conveniently support a more suitable portion of the expansion valve 300, thereby improving the supporting effect.

[0073] In some embodiments, the avoidance hole 124 can be formed by a material removal process, that is, a piece of material can be removed from the connecting plate body 120 by laser cutting, wire cutting or stamping, thereby forming the avoidance hole 124. In some embodiments, when the fixed bracket 100 is an injection molded part, the avoidance hole 124 can be produced when the fixed bracket 100 is integrally injection molded. In particular, in one embodiment, when the fixed bracket 100 is a sheet metal part, the avoidance hole 124 and the supporting portion 130 can be formed at the same time. Specifically, the material at the position of the avoidance hole 124 of the connecting plate body 120 can be stamped and bent by a stamping process, and the bent material is formed into the supporting portion 130, and the punched hole position is the avoidance hole 124. In other words, during the forming process of the avoidance hole 124, the material at the position of the avoidance hole 124 is not removed, but is processed into the supporting portion 130 by a bending process. In this solution, on the one hand, the avoidance hole 124 and the supporting portion 130 are formed simultaneously, so the processing efficiency is higher; on the other hand, less waste is generated during the forming process of the fixed bracket 100, the material utilization efficiency is higher, and the material cost is lower.

[0074] See also Figure 7-Figure 8 ,as well as Figure 12-14 In some embodiments, the heat exchange assembly 200 includes a heat exchange body 210 and an outer plate 220 connected to the outer periphery of the heat exchange body 210, and the outer plate 220 has a side wall surface 224 facing the expansion valve 300 and a peripheral wall surface 223 adjacent to the side wall surface 224. Specifically, when the outer plate 220 includes an upper plate body 221 and side plates 222 located on both sides of the upper plate body 221, the wall surfaces of the upper plate body 221 and the two side plates 222 facing the expansion valve 300 are all part of the side wall surface 224, and the upper wall surface of the upper plate body 221 and the wall surfaces of the two side plates 222 facing away from each other are all part of the peripheral wall surface 223. The fixing bracket 100 also includes a connecting plate body 120, and the connecting plate body 120 is respectively connected to the fixing portion 110 and the supporting portion 130. The fixing part 110 includes a first plate 111 and a second plate 112 that are bent to each other, and the first plate 111 is suitable for fitting the peripheral wall surface 223, the second plate 112 is suitable for fitting the side wall surface 224, and the second plate 112 is connected to the connecting plate 120. In this solution, the fixing part 110 includes two plates that are bent to each other, and the two plates are respectively fitted to two wall surfaces that are arranged adjacent to each other, which improves the connection stability of the fixing part 110 and facilitates the positioning of the fixing part 110 during installation. For example, when the fixing part 110 is installed, by making the second plate 112 abut against the side wall surface 224, the first plate 111 is positioned in a direction perpendicular to the side wall surface 224, which facilitates the assembly of the fixing part 110.

[0075] When the fixing portion 110 includes a first plate body 111 and a second plate body 112, and the first plate body 111 is attached to the peripheral wall surface 223, and the second plate body 112 is attached to the side wall surface 224, see Figure 7-Figure 8 In some embodiments, the fixing portion 110 may be connected to the upper plate 221 of the outer plate 220, and the first plate 111 is connected to the upper wall surface (i.e., the peripheral wall surface 223) of the upper plate 221, and the second plate 112 is connected to the wall surface (i.e., the side wall surface 224) of the upper plate 221 facing the expansion valve 300. Figure 12-14 In other embodiments, the fixing portion 110 may also be connected to the side plate body 222 of the outer plate 220, and the first plate body 111 is connected to the wall surface of the side plate body 222 facing away from the expansion valve 300 (i.e., the peripheral wall surface 223), and the second plate body 112 is connected to the wall surface of the side plate body 222 facing the expansion valve 300 (i.e., the side wall surface 224).

[0076] The supporting portion 130 can support the bottom of the expansion valve 300, the first tube body 230 or the second tube body 240 (hereinafter, the supporting portion 130 supporting the expansion valve 300 is taken as an example). Figure 1 In some embodiments, the supporting portion 130 may be a bottom plate 133 extending laterally, and after the fixing bracket 100 is installed, the bottom plate 133 is located below the expansion valve 300. In order to further enhance the supporting effect of the supporting portion 130 and the limiting effect on the expansion valve 300, see Figure 2-Figure 5 In some embodiments, the outer end of the bottom plate 133 extending laterally of the supporting portion 130 is bent upward to form a second baffle 132, and the second baffle 132 can limit the expansion valve 300. At this time, the connecting plate body 120 participates in the limiting. Specifically, the connecting plate body 120 and the second baffle 132 are respectively located on both sides of the expansion valve 300 in the lateral direction, thereby jointly limiting the displacement of the expansion valve 300 in the lateral direction. Figure 6 as well as Fig.15 In some embodiments, the supporting portion 130 includes a first baffle 131, a bottom plate 133, and a second baffle 132. The first baffle 131 is connected to the fixing portion 110, the second baffle 132 is arranged with the first baffle 131 in a lateral direction, and the bottom plate 133 connects the bottom sides of the first baffle 131 and the second baffle 132. After the fixing bracket 100 is installed, the bottom plate 133 is located at the lower end of the expansion valve 300, and the first baffle 131 and the second baffle 132 are respectively located on both sides of the expansion valve 300 in the lateral direction, so that the supporting portion 130 can not only limit the displacement of the expansion valve 300 in the vertical direction, but also limit the displacement of the expansion valve 300 in the lateral direction.

[0077] In order to improve the limiting effect on the expansion valve 300, in some embodiments, the fixing bracket 100 further includes a fixing band (not shown in the figure), which is suitable for fixing at least one of the expansion valve 300, the first tube body 230 or the second tube body 240 to the supporting portion 130. Specifically, when the supporting portion 130 supports the first tube body 230, the fixing band is arranged around the axis of the first tube body 230 and connected to the supporting portion 130, so that the first tube body 230 cannot be separated from the supporting portion 130, thereby improving the limiting effect on the expansion valve 300. When the supporting portion 130 includes a plurality of supporting arms, a plurality of fixing bands may be provided accordingly. For example, when the supporting portion 130 includes the first supporting arm 135 and the second supporting arm 136, two fixing straps may be provided, wherein one fixing strap is used to tie one of the expansion valve 300, the first tube body 230 or the second tube body 240 to the first supporting arm 135, and the other fixing strap is used to tie the other of the expansion valve 300, the first tube body 230 or the second tube body 240 to the second supporting arm 136. The fixing strap is a flexible strap, which may be made of any material used for tying. In one embodiment, the fixing strap may be a nylon tie, one end of which is provided with a tie opening, and the other end can be passed through the tie opening so as to be unidirectionally limited at the tie opening to achieve a tying effect.

[0078] See also Figure 6 as well as Fig.15 In some embodiments, the supporting portion 130 is provided with a notch 134, and the fixing strap is embedded in the notch 134, so as to achieve the positioning of the fixing strap and prevent the fixing strap from being separated from the supporting portion 130. Specifically, at least one of the first baffle 131, the second baffle 132 and the bottom plate 133 is provided with a notch 134 to achieve the limiting of the fixing strap. In this embodiment, the first baffle 131 is provided with a notch 134. In other embodiments, the upper ends of the first baffle 131 and the second baffle 132 can also be provided with a notch 134, so that when the fixing strap is embedded in the notch 134 of the first baffle 131 and the second baffle 132, the limiting effect of the components located between the first baffle 131 and the second baffle 132 can be improved.

[0079] In some embodiments, the fixing bracket 100 further includes a buffer layer 140 (not shown in the figure), which is disposed on the supporting portion 130 for supporting the wall surface of at least one of the expansion valve 300, the first tube body 230 and the second tube body 240. The buffer layer 140 can be made of any buffer material, and specifically, the material of the buffer layer 140 can be silicone, rubber, polyethylene foam or polyurethane foam. The buffer layer 140 can be disposed on any wall surface of the supporting portion 130 for contacting at least one of the expansion valve 300, the first tube body 230 and the second tube body 240. Specifically, when the supporting portion 130 includes a first baffle 131, a second baffle 132 and a bottom plate 133, the buffer layer 140 can be connected to the wall surface of the first baffle 131 facing the second baffle 132, the wall surface of the second baffle 132 facing the first baffle 131 and the upper wall surface of the bottom plate 133.

[0080] See also Figure 1-Figure 15 The embodiment of the second aspect of the present application further provides a heat exchange unit 10, which includes a fixed bracket 100, a heat exchange assembly 200 and an expansion valve 300 in any of the above embodiments. Compared with the related art, in this embodiment, since the fixed bracket 100 is added to support the expansion valve 300, the pipe body connected to the expansion valve 300 is less likely to be non-elastically deformed due to the bumping during the transportation of the heat exchange unit 10.

[0081] The embodiment of the third aspect of the present application further provides an air conditioner, the air conditioner comprising the heat exchange unit 10 in any of the above embodiments. The air conditioner may also include a housing, a compressor, a liquid storage tank, and an air supply assembly, etc., and the heat exchange unit 10, the compressor, the liquid storage tank, and the air supply assembly are all arranged in the housing. In view of the improvement of the fixing bracket 100, the air conditioner in this embodiment has the effect that the pipe body connected to the expansion valve 300 is less likely to produce non-elastic deformation during transportation.
