The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] Reference below Figure 1-Figure 14 A heat exchanger assembly 2 according to an embodiment of the present invention is described.

[0041] Reference Figure 4-Figure 6 According to the heat exchanger assembly 2 of the first embodiment of the utility model, the heat exchanger assembly 2 includes a heat exchanger component 21, a heat exchanger bracket 22 and a pipe pressure plate 23.

[0042] The heat exchanger bracket 22 includes a pipe fixing structure 221, and the pipe fixing structure 221 includes a clamping portion 222 and a pipe connecting the clamping portion 222 along a first direction (for example, referring to Figure 4The first mounting portion 223 and the second mounting portion 224 are on opposite sides of the pipe fixing structure 221 (e1 direction in the figure), and the first mounting portion 223 is formed with a slot 225; the pipe pressing plate 23 is installed on the pipe fixing structure 221, and the pipe pressing plate 23 includes a pipe pressing portion 231 and a first connecting portion 232 and a second connecting portion 233 connected to the pipe pressing portion 231 on opposite sides of the first direction. The pipe pressing portion 231 is located at the clamping portion 222 along the second direction (for example, refer to Figure 5 The tube pressing portion 231 and the clamping portion 222 define a clamping space for clamping the heat exchanger pipe 26. The first connecting portion 232 is suitable for being inserted into the slot 225 along the second direction, and the second connecting portion 233 is connected to the second mounting portion 224.

[0043] The card slot 225 can facilitate the installation of the first connecting part 232 on the piping fixing structure 221, so that the overall structure of the piping pressure plate 23 and the piping fixing structure 221 is compact. The card slot 225 and the first connecting part 232 are snap-fitted to each other, so that the disassembly or installation between the piping pressure plate 23 and the piping fixing structure 221 can be facilitated. The card slot 225 can also play a positioning role for the first connecting part 232, so that the assembly position of the piping pressure plate 23 on the piping fixing structure 221 is accurate. Moreover, the card slot 225 that is snap-fitted to the first connecting part 232 is formed on the first mounting part 223, which can simplify the molding process of the piping fixing structure 221, reduce the mold production cost, and improve production reliability.

[0044] The pressing tube portion 231 is located on one side of the clamping portion 222 along the second direction, and the pressing tube portion 231 and the clamping portion 222 jointly define a clamping space for clamping the heat exchanger piping 26.

[0045] The cooperation between the piping fixing structure 221 and the piping pressing plate 23 can be used to fix the heat exchanger piping 26 and enhance the connection stability between the heat exchanger piping 26 and the heat exchanger component 21. By moving the piping pressing plate 23 along the second direction and toward the direction close to the piping fixing structure 221, the clamping portion and the clamping portion 222 cooperate to clamp and fix the heat exchanger piping 26. At the same time, the first connecting portion 232 can be inserted into the slot 225 of the first mounting portion 223 along the second direction, and the second connecting portion 233 is aligned and connected with the second mounting portion 224. This can make the assembly between the piping pressing plate 23 and the piping fixing structure 221 more convenient, thereby improving the assembly efficiency of the piping pressing plate 23 on the heat exchanger bracket 22.

[0046] For example, the assembly process of the piping pressing plate 23 on the heat exchanger bracket 22 can be as follows: clamp the heat exchanger piping 26 in the clamping portion 222 of the piping fixing structure 221, move the piping pressing plate 23 along the second direction and in the direction close to the heat exchanger bracket 22 to the piping fixing structure 221, so that the clamping portion is located at a position opposite to the clamping portion 222 and the clamping portion and the clamping portion 222 jointly clamp and fix the heat exchanger piping 26, and the first connecting portion 232 is smoothly inserted into the slot 225 of the first mounting portion 223 along the second direction, and the second connecting portion 233 is aligned and connected with the second mounting portion 224, thereby completing the assembly of the piping pressing plate 23 and the piping fixing structure 221, and making the assembly between the piping pressing plate 23 and the heat exchanger bracket 22 more convenient.

[0047] For example, the first direction may be parallel to the left-right direction; for another example, the first direction may also have an angle with the left-right direction.

[0048] For example, the angle between the first direction and the left-right direction is less than 30°, and the angle between the first direction and the left-right direction may be 3°, 5°, 10°, 15°, 25°, etc.

[0049] For example, the second direction may be parallel to the front-rear direction; for another example, the second direction may also be at an angle to the front-rear direction.

[0050] For example, the angle between the second direction and the front-rear direction is less than 30°, and the angle between the second direction and the front-rear direction may be 3°, 5°, 10°, 15°, 25°, etc.

[0051] According to the heat exchanger assembly 2 of the embodiment of the utility model, a slot 225 is formed on the heat exchanger bracket 22, so that the piping pressure plate 23 is moved along the second direction and in the direction close to the heat exchanger bracket 22, and the clamping portion and the clamping portion 222 cooperate to clamp and fix the heat exchanger piping 26. At the same time, the first connecting portion 232 can be inserted into the slot 225 of the first mounting portion 223 along the second direction, and the second connecting portion 233 is aligned and connected with the second mounting portion 224, so that the assembly between the piping pressure plate 23 and the piping fixing structure 221 can be more convenient, thereby improving the assembly efficiency of the piping pressure plate 23 on the heat exchanger bracket 22.

[0052] Reference Figure 6 and Figure 7 According to some embodiments of the present utility model, the slot 225 penetrates the first mounting portion 223 along the second direction, and the first connecting portion 232 includes a straight insertion section 234 and a flange section 235 which are arranged at an angle, the straight insertion section 234 is connected between the pressing tube portion 231 and the flange section 235, and there is a first angle α between the straight insertion section 234 and the pressing tube portion 231, and the straight insertion section 234 is suitable for inserting the slot 225 along the second direction. In the second direction, the flange section 235 is located on the side of the first mounting portion 223 away from the pressing tube portion 231 and is in contact with the flange section 235 and the first mounting portion 223. The flange section 235 can enhance the overall structural strength of the piping pressure plate 23. The slot 225 penetrates the first mounting portion 223 along the second direction, which can facilitate the straight insertion section 234 to penetrate the slot 225, so that the first connection portion 232 is inserted into the slot 225 along the second direction, and the flange section 235 is located on the side of the first mounting portion 223 away from the pipe pressing portion 231 and the flange section 235 is in contact with the first mounting portion 223, which can enhance the connection stability between the first connection portion 232 and the first mounting portion 223, and reduce the possibility of the first connection portion 232 being detached from the slot 225 due to the vibration of the heat exchanger component 21 when the heat exchanger component 21 is working; through the contact connection between the flange section 235 and the first mounting portion 223, the disassembly or installation between the first connection portion 232 and the first mounting portion 223 of the piping pressure plate 23 can also be made more convenient.

[0053] Reference Fig.10 and Fig.14According to some embodiments of the utility model, the width w1 of the slot 225 in the first direction is greater than the width w2 of the flange section 235 in the first direction, ensuring that the flange section 235 can pass through the slot 225 smoothly; the length w3 of the straight insertion section 234 in the second direction is greater than the depth w4 of the slot 225 in the second direction, ensuring that the straight insertion section 234 can pass through the slot 225 so that the flange section 235 passes through the slot 225 and the flange section 235 is located on the side of the first mounting portion 223 away from the tube pressing portion 231. By making the width w1 of the slot 225 in the first direction greater than the width w2 of the flange section 235 in the first direction, and the length w3 of the straight insertion section 234 in the second direction greater than the depth w4 of the slot 225 in the second direction, it is ensured that the straight insertion section 234 and the flange section 235 can be smoothly inserted into the slot 225 along the second direction, and it can be ensured that the flange section 235 passes through the slot 225 so as to contact the side of the first mounting portion 223 away from the pressing tube portion 231.

[0054] Reference Fig.14 According to some embodiments of the present invention, the first angle α is an obtuse angle. For example, the first angle α can be 95°, 100°, 120°, 135°, 150°, 160°, etc. By making the first angle α between the straight-insertion section 234 and the pipe pressing section 231 an obtuse angle, the space in the second direction is fully utilized, and the straight-insertion section 234 is conveniently inserted into the card slot 225 along the second direction, so that the card connection between the first connecting portion 232 and the first mounting portion 223 is more labor-saving, thereby making the assembly between the pipe pressing plate 23 and the pipe fixing structure 221 more convenient.

[0055] Reference Fig.14According to some embodiments of the present invention, the pressing tube portion 231 includes a first pressing tube section 236, a second pressing tube section 237 and a third pressing tube section 238 which are connected in sequence, the first pressing tube section 236 is connected between the straight insertion section 234 and the second pressing tube section 237, and the third pressing tube section 238 is connected between the second pressing tube section 237 and the second connecting portion 233. The pressing tube section 231 is divided into three sections, namely, a first pressing tube section 236, a second pressing tube section 237 and a third pressing tube section 238, which are interconnected. The first pressing tube section 236 is connected to the straight insertion section 234, and can play a transitional role between the second pressing tube section 237 and the straight insertion section 234, for example, the straight insertion section 234 can be smoothly turned into the second direction, so that the straight insertion section 234 can be smoothly inserted into the slot 225 along the second direction; the second pressing tube section 237 is connected to the first pressing tube section 236 and the third pressing tube section 238, and can be used to change the direction between the pressing tube section 231 and the straight insertion section 234 to adapt to different angle requirements, thereby making the overall structure of the pressing tube section 231 and the pipe fixing structure 221 more compact; the third pressing tube section 238 is connected to the second pressing tube section 231 and the second connecting section 233, and can be used to change the direction between the pressing tube section 231 and the second connecting section 233 to adapt to different angle requirements, so that the second connecting section 233 can smoothly transition to the required angle direction.

[0056] There is a first angle α between the straight-insertion section 234 and the first pressing tube section 236, a second angle β between the second pressing tube section 237 and the first pressing tube section 236, a third angle γ between the second pressing tube section 237 and the third pressing tube section 238, and a fourth angle θ between the third pressing tube section 238 and the second connecting portion 233. There is a first angle α between the straight-insertion section 234 and the first pressing tube section 236, and a second angle β between the second pressing tube section 237 and the first pressing tube section 236. For example, the straight-insertion section 234 extends along the second direction, and the second pressing tube section 237 extends along the first direction, so that the turning between the straight-insertion section 234 and the second pressing tube section 237 can be smoother; there is a third angle γ between the second pressing tube section 237 and the third pressing tube section 238, and a fourth angle θ between the third pressing tube section 238 and the second connecting portion 233, for example, the second connecting portion 233 can be made smoother. The connecting portion 233 and the second pressing tube section 237 are spaced apart along the second direction, and the second pressing tube section 237 and the second connecting portion 233 are connected by the third pressing tube section 238, and a third angle γ is defined between the third pressing tube section 238 and the second pressing tube section 237, and a fourth angle θ is defined between the third pressing tube section 238 and the second connecting portion 233, so that the second pressing tube section 237 and the second connecting portion 233 can form a continuous structure, and the turning transition between the second pressing tube section 237 and the second connecting portion 233 can be smoother.

[0057] Reference Fig.14According to some embodiments of the present invention, the first angle α, the second angle β, the third angle γ and the fourth angle θ are all obtuse angles. For example, the first angle α can be 95°, 100°, 120°, 135°, 150°, 160°, etc., the second angle β can be 95°, 100°, 120°, 135°, 150°, 160°, etc., the third angle γ can be 95°, 100°, 120°, 135°, 150°, 160°, etc., the fourth angle θ can be 95°, 100°, 120°, 135°, 150°, 160°, etc., through the straight insertion section 234 and The first angle α between the first pressing tube section 236 is an obtuse angle, and the first pressing tube section 236 and the second pressing tube section 237β are obtuse angles, which can make the turning between the straight insertion section 234 and the second pressing tube section 237 smoother; the third angle γ between the second pressing tube section 237 and the third pressing tube section 238 is an obtuse angle, and the fourth angle θ between the third pressing tube section 238 and the second connecting part 233 is an obtuse angle, which can make the turning transition between the second pressing tube section 237 and the second connecting part 233 smoother.

[0058] By making the first angle α, the second angle β, the third angle γ and the fourth angle θ all obtuse angles, the turning transition between the straight insertion section 234 and the second pressing tube section 237 can be made smoother, and the turning transition between the second pressing tube section 237 and the second connecting portion 233 can be made smoother, so that the turning transition between the first connecting portion 232 of the piping pressing plate 23 and the pressing tube portion 231 can be made smoother, and the turning transition between the second connecting portion 233 and the pressing tube portion 231 can be made smoother.

[0059] For example, when the heat exchanger piping 26 is located at the clamping portion 222 of the piping fixing structure 221, at least a portion of the heat exchanger piping 26 protrudes from the clamping portion 222 of the piping fixing structure 221 along the second direction, and a first angle α is formed between the first pipe pressing section 236 and the straight insertion section 234 of the piping pressing plate 23, a second angle β is formed between the second pipe pressing section 237 and the first pipe pressing section 236, a third angle γ is formed between the second pipe pressing section 237 and the third pipe pressing section 238, and a fourth angle θ is formed between the third pipe pressing section 238 and the second connecting portion 233. The first angle α, the second angle β, the third angle γ and the fourth angle θ are all obtuse angles, which can make the overall structure of the piping pressing plate 23 and the heat exchanger piping 26 more compact, reduce space occupancy, and avoid interference between the piping pressing plate 23 and the heat exchanger piping 26 during assembly, making the assembly of the piping pressing plate 23 on the piping fixing structure 221 more convenient.

[0060] Reference Figure 11-13According to some embodiments of the present invention, the tube pressing portion 231 is formed with a convex structure 239 protruding away from the clamping portion 222. The convex structure 239 can enhance the structural strength of the tube pressing portion 231, thereby enhancing the overall structural strength of the piping pressing plate 23.

[0061] Reference Fig.11 and Fig.12 According to some embodiments of the present invention, at least the pressure tube portion 231 is along the third direction (for example, referring to Figure 1 The folding structure 240 is formed on two opposite sides of the pipe pressing plate 23 (in the vertical direction). The folding structure 240 can enhance the overall structural strength of the pipe pressing plate 23 and prevent the opposite sides of the pipe pressing portion 231 along the third direction from directly pressing the heat exchanger pipe 26 and scratching the heat exchanger pipe 26.

[0062] For example, the pipe pressing plate 23 is a metal part, and the surface of the heat exchanger pipe 26 is covered with thermal insulation cotton. By forming a folding structure 240 on at least two opposite sides of the pressing pipe part 231 along the third direction, it can be avoided that when the pressing pipe part 231 provides a clamping force on the heat exchanger pipe 26, the opposite sides of the pressing pipe part 231 along the third direction may avoid scratching the thermal insulation cotton on the surface of the heat exchanger pipe 26 due to the sharp edges.

[0063] Reference Figure 11-13 According to some embodiments of the present invention, the tube pressing portion 231 is formed with a convex structure 239 protruding away from the clamping portion 222, and at least two opposite sides of the tube pressing portion 231 along the third direction are formed with a folding structure 240. The convex structure 239 can enhance the structural strength of the tube pressing portion 231, thereby enhancing the overall structural strength of the pipe pressing plate 23; and the folding structure 240 can enhance the overall structural strength of the pipe pressing plate 23, and can prevent the opposite sides of the tube pressing portion 231 along the third direction from directly pressing the heat exchanger pipe 26 and scratching the heat exchanger pipe 26.

[0064] Reference Figure 4 and Figure 5 According to some embodiments of the utility model, the second connecting portion 233 and the second mounting portion 224 are connected by a fastener 25, which can make the connection between the second connecting portion 233 and the second mounting portion 224 simple and have strong stability, and facilitate the disassembly or installation between the second connecting portion 233 and the second mounting portion 224.

[0065] The fastener 25 is suitable for passing through the second connecting portion 233 and the second mounting portion 224 along the second direction. Since the second mounting portion 224 is connected to one side of the piping fixing structure 221 along the first direction, and the second connecting portion 233 is connected to one side of the piping pressing plate 23 along the first direction, the fastener 25 is passed through the second connecting portion 233 and the second mounting portion 224 along the second direction. When the piping pressing plate 23 moves along the second direction and toward the direction close to the heat exchanger bracket 22, the pipe pressing portion 231 of the piping pressing plate 23 can cooperate with the clamping portion 222 of the heat exchanger bracket 22 to clamp and fix the heat exchanger piping 26. Moreover, the fastener 25 is passed through the second connecting portion 233 and the second mounting portion 224 along the second direction, so that the second connecting portion 233 and the second mounting portion 224 can be aligned and the fixed connection between the second connecting portion 233 and the second mounting portion 224 can be achieved through the fastener 25, so that the fixed connection between the second connecting portion 233 and the second mounting portion 224 is more convenient.

[0066] For example, the installation process of the piping pressing plate 23 on the heat exchanger bracket 22 can be as follows: move the piping pressing plate 23 along the second direction and toward the direction close to the heat exchanger bracket 22, so that the pipe pressing part 231 of the piping pressing plate 23 is opposite to the clamping part 222 of the piping fixing structure 221 of the heat exchanger bracket 22, so as to clamp and fix the heat exchanger piping 26, and at the same time, make the first connecting part 232 snap into the slot 225 of the first mounting part 223 along the second direction to achieve a snap connection between the first connecting part 232 and the first mounting part 223, and make the second connecting part 233 and the second mounting part 224 aligned, so that the fastener 25 is passed through the second connecting part 233 and the second mounting part 224 along the second direction, and the fixed connection between the second connecting part 233 and the second mounting part 224 can be achieved, so that the assembly between the piping pressing plate 23 and the heat exchanger bracket 22 is more convenient.

[0067] Reference Figure 8-Figure 10According to some embodiments of the present invention, the surface of the clamping portion 222 facing the clamping space includes one or more clamping surfaces 226 arranged along the first direction, the cross section of the heat exchanger pipe 26 is annular, and the clamping surface 226 is an arc-shaped concave in the direction away from the pressing pipe portion 231. The clamping portion 222 is used to fix and support the heat exchanger pipe 26. The surface of the clamping portion 222 facing the clamping space includes one or more clamping surfaces 226 arranged along the first direction. For example, if there are one or more heat exchanger pipes 26, it is convenient for one or more heat exchanger pipes 26 to contact with one or more clamping surfaces 226, and it can simultaneously fix and support one or more heat exchanger pipes 26. A clamping force can be applied to one or more heat exchanger pipes 26 to ensure that the heat exchanger pipe 26 can be firmly and reliably fixed to the clamping portion 222, and multiple heat exchanger pipes 26 can be arranged in order along the first direction to avoid interference between multiple heat exchanger pipes 26.

[0068] In addition, the cross-section of the heat exchanger piping 26 is circular, and the clamping surface 226 is an arc-shaped arc that is concave in the direction away from the pressing pipe portion 231, which can increase the contact area between the clamping surface 226 and the heat exchanger piping 26. The clamping portion 222 can better wrap at least a portion of the heat exchanger piping 26, enhance the clamping force of the clamping portion 222 on the heat exchanger piping 26, and thus enhance the connection stability between the piping fixing structure 221 and the heat exchanger piping 26.

[0069] Reference Figure 5 , Figure 8 and Fig. 9 According to some embodiments of the present invention, the heat exchanger bracket 22 includes a water receiving tray 227 located at the lower end of the heat exchanger bracket 22, the water receiving tray 227 is located on the bottom surface of the heat exchanger component 21, and part of the side wall of the water receiving tray 227 constitutes the piping fixing structure 221.

[0070] The water receiving tray 227 can collect condensed water or other liquids generated during the operation of the heat exchanger component 21. Since the water receiving tray 227 is located on the bottom surface of the heat exchanger component 21, the condensed water or other liquids generated during the operation of the heat exchanger component 21 can fall into the water receiving tray 227 under its own gravity, thereby reducing the possibility that the condensed water or other liquids generated during the operation of the heat exchanger component 21 directly flow to the outside of the heat exchanger assembly 2 and damage the components outside the heat exchanger assembly 2.

[0071] Part of the side wall of the water receiving tray 227 constitutes the pipe fixing structure 221 , which can enhance the stability of the pipe fixing structure 221 , thereby enhancing the stability of the heat exchanger pipe 26 located between the pipe fixing structure 221 and the pipe pressing plate 23 .
