The first heat exchanger includes a first manifold and a plurality of first tubes, and the second heat exchanger includes a second manifold. Solder is filled in the splice between the first manifold and the second manifold to achieve a welded connection between the first manifold and the second manifold. However, the splice between the first manifold and the plurality of first tubes also needs to be filled with solder separately to achieve a welded connection between the first manifold and the plurality of first tubes, making the welding process relatively complex.

[0006] In this application, a first current collector core is welded to multiple first tubes through a first welding layer, and a first welding layer is welded to a second current collector core.

[0017] The heat exchange components of exemplary embodiments of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can complement or combine with each other.

[0018] According to a specific embodiment of the heat exchange component of this application, such as Figures 1 to 7As shown, the heat exchange assembly 1000 includes a first heat exchanger 100 and a second heat exchanger 200, which are arranged side by side. A fan is provided on one side of the first heat exchanger 100 and the second heat exchanger 200 to accelerate the heat exchange between the first heat exchanger 100, the second heat exchanger 200 and the air. For example, the first heat exchanger 100 is a low-temperature radiator, and the second heat exchanger 200 is an outdoor heat exchanger.

[0019] The first heat exchanger 100 contains a coolant that exchanges heat with the air. The first heat exchanger 100 primarily utilizes the principles of natural convection and forced ventilation to exchange heat between the cooling medium and the outside air, dissipating heat and achieving cooling. Specifically, a fan blows across the first heat exchanger 100, carrying away heat from it. The temperature difference between the first heat exchanger 100 and the outside air, combined with natural convection, allows heat to be transferred from the first heat exchanger 100 to the outside air, thus achieving heat dissipation.

[0020] The second heat exchanger 200 contains refrigerant, which exchanges heat with the air.

[0021] In some embodiments, such as Figures 1 to 4 As shown, the first heat exchanger 100 includes a first manifold 110, a first welded layer 120, and a plurality of first tubes 130. The second heat exchanger 200 includes a second manifold 210. The first welded layer 120 welds the first manifold 110 and the second manifold 210 together. The first welded layer 120 extends at least from the second manifold 210 to the plurality of first tubes 130, thus enabling a single welded layer to complete the welding connection between the first manifold 110 and the first tubes 130, and between the first manifold 110 and the second manifold 210, simplifying the welding process. The area of ​​the side of the first welded layer 120 closest to the first manifold 110 is the same as the area of ​​the side of the first manifold 110 closest to the first welded layer 120. For example, the first tubes 130 are flat tubes.

[0022] In some embodiments, the first side 111 of the first current collector 110 is parallel to the length direction of the plurality of first tubes 130, and the second side 211 of the first current collector 110 is also parallel to the length direction of the plurality of first tubes 130. The first side 111 of the first current collector 110 is welded to the second side 211 of the second current collector 210 through a first welding layer 120. In this way, after the first side 111 of the first current collector 110 and the second side 211 of the second current collector 210 are welded together, the welding connection surface can be kept approximately parallel to the first tubes 130, avoiding the probability of the welding connection surface touching the first tubes 130.

[0023] The second heat exchanger 200 also includes a second welded layer 220 and a plurality of second tubes 230. The first welded layer 120 is disposed on the outer peripheral surface of the first manifold 110, and the second welded layer 220 is disposed on the outer peripheral surface of the second manifold 210. For example, the second tubes 230 are flat tubes.

[0024] The first welding layer 120 and the second welding layer 220 weld the first current collector 110 and the second current collector 210. The first current collector 110 and the first welding layer 120 can be formed by rolling and welding a single plate or by rolling and welding two plates. The plate includes a substrate layer and a composite layer. The substrate layer forms the first current collector 110, and the composite layer forms the first welding layer 120. That is, the substrate layer is rolled to form the first current collector 110, and the composite layer is rolled to form the first welding layer 120, with both the substrate layer and the composite layer being rolled simultaneously. The second current collector 210 and the second welding layer 220 are similar. The materials of the first current collector 110, the second current collector 210, the first tube 130, and the second tube 230 are all aluminum alloys.

[0025] The primary components of the first weld layer 120 and the second weld layer 220 are metal alloys. Different types of weld layers have different compositions. For example, the main components of the aluminothermic weld layer include sodium fluoride, sodium chloride, alumina, and titanium dioxide, while auxiliary components include ammonium chloride, aluminum carbide, and silicon carbide. The main function of the weld layer is to lower the melting point and oxide film of aluminum, promote the flow of the molten aluminum pool, and improve weld quality. Sodium fluoride mainly acts as a flux and welding agent, allowing aluminum to melt at low temperatures and promoting the formation and flow of the molten aluminum pool. Sodium chloride plays a similar role to sodium fluoride and also reduces viscosity, making the molten aluminum pool easier to flow. Alumina acts as a penetrant and removes the oxide film, promoting the formation and flow of the molten aluminum pool. Titanium dioxide mainly removes the oxide film, improving weld quality. In addition to the above main components, the aluminothermic weld layer also contains some auxiliary components, such as ammonium chloride, aluminum carbide, and silicon carbide. Ammonium chloride increases surface tension, making the molten aluminum pool easier to flow and removing the oxide film. Aluminum carbide acts as a reducing agent, removing oxide films and forming a protective layer in the molten aluminum pool, thus improving weld quality. Silicon carbide reduces the surface tension of the molten aluminum pool, promoting pool formation and flow, while also removing oxide films.

[0026] The first welding layer 120 welds the first collector core 110 to multiple first tubes 130. The second welding layer 220 welds the second collector core 210 to multiple second tubes 230. The first welding layer 120 and the second welding layer 220 weld the first collector core 110 and the second collector core 210. By having the first welding layer 120 disposed on the outer peripheral surface of the first collector core 110 and the second welding layer 220 disposed on the outer peripheral surface of the second collector core 210, the two welding layers complete the connection between the collector and the tubes, and between collectors, reducing the connection cost of the heat exchange assembly.

[0027] The first current collector 110 has a weld layer (first weld layer 120) between it and the plurality of first tubes 130, and the second current collector 210 has a weld layer (second weld layer 220) between it and the plurality of second tubes 230. The first current collector 110 and the second current collector 210 have two weld layers (first weld layer 120 and second weld layer 220). One weld layer between the first current collector 110 and the second current collector 210 is sufficient for welding requirements, while two weld layers enhance the welding strength.

[0028] In some embodiments, the area of ​​the first welding layer 120 is the same as the area of ​​the outer peripheral surface of the first current collector 110, and the area of ​​the second welding layer 220 is the same as the area of ​​the outer peripheral surface of the second current collector 210. That is, the first welding layer 120 completely covers the outer peripheral surface of the first current collector 110, and the second welding layer 220 completely covers the outer peripheral surface of the second current collector 210, making the thickness of the first current collector 110 and the second current collector 210 uniform at all points, thus reducing the processing difficulty.

[0029] The first current collector 110 and the second current collector 210 are welded together by the first welding layer 120 and the second welding layer 220, which reduces the distance between the first current collector 110 and the second current collector 210, reduces the space occupied by the first current collector 110 and the second current collector 210, and reduces the connection cost between the first current collector 110 and the second current collector 210.

[0030] The area of ​​the side of the second weld layer 220 near the second current collector 210 is the same as the area of ​​the side of the second current collector 210 near the second weld layer 220. The first side 111 of the first current collector 110 is parallel to the length direction of the plurality of second tubes 230, the second side 211 of the second current collector 210 is parallel to the length direction of the plurality of second tubes 230, and the fourth side 212 of the second current collector 210 near the plurality of second tubes 230 is perpendicular to the second side 211 of the second current collector 210 near the first current collector 110. In this way, after the first side 111 of the first current collector 110 and the second side 211 of the second current collector 210 are welded together, the welding connection surface can be kept approximately parallel to the second tubes 230, avoiding the probability of the welding connection surface touching the second tubes 230.

[0031] The third side 112 of the first current collector 110 near the plurality of first tubes 130 is perpendicular to the first side 111 of the first current collector 110 near the second current collector 210, and the side of the second current collector 210 near the plurality of second tubes 230 is perpendicular to the side of the second current collector 210 near the first current collector 110. This facilitates the insertion of the first tube 130 into the first current collector 110, reducing contact between the first tube 130 and the side of the first current collector 110 near the second current collector 210; it also facilitates the insertion of the second tube 230 into the second current collector 210, reducing contact between the second tube 230 and the side of the second current collector 210 near the first current collector 110.

[0032] In some embodiments, such as Figures 3 to 5 As shown, the first tube 130 includes a first tube core 131 and a third welding layer 132, with the third welding layer 132 disposed on the outer peripheral surface of the first tube core 131. The second tube 230 includes a second tube core 231 and a fourth welding layer 232, with the fourth welding layer 232 disposed on the outer peripheral surface of the second tube core 231. The third welding layer 132 and the first welding layer 120 are welded together to connect the first current collector 110 and the first tube core 131. The fourth welding layer 232 and the second welding layer 220 are welded together to connect the second current collector 210 and the second tube core 231. Thus, there are two welding layers (the third welding layer 132 and the first welding layer 120) between the first current collector 110 and the first tube core 131, which can enhance the welding strength between the first current collector 110 and the first tube core 131. The second current collector 210 and the second tube core 231 have two welding layers (fourth welding layer 232 and second welding layer 220), which can enhance the welding strength between the second current collector 210 and the second tube core 231.

[0033] like Figure 6 and Figure 7As shown, the heat exchange assembly 1000 also includes multiple fins 300. The first end of each fin 300 is connected to the fifth side surface 133 of the first tube 130, and the second end of each fin 300 is connected to the sixth side surface 233 of the second tube 230. The fifth side surface 133 and the sixth side surface 233 are located in the same plane. That is, the first heat exchanger 100 and the second heat exchanger 200 share the fins 300. The main function of the fins 300 is to increase the heat exchange area of ​​the first heat exchanger 100 and the second heat exchanger 200, thereby improving heat exchange efficiency. Another function of the fins 300 is to connect the first tube 130 and the second tube 230, strengthening the connection between the first heat exchanger 100 and the second heat exchanger 200. Of course, the fins 300 can also be partially connected only to the first tube 130 and not to the second tube 230, and partially connected only to the second tube 230 and not to the first tube 130. That is, the first heat exchanger 100 and the second heat exchanger 200 do not share fins. This application is not limited to this.

[0034] In some embodiments, the first pipe 130 is a type B pipe, and the second pipe 230 is a folded porous pipe or an extruded porous pipe. Since the coolant flows in the first pipe 130, which has a relatively low pressure, a type B pipe is sufficient to meet the coolant's pressure requirements. However, the refrigerant flows in the second pipe 230, which has a higher operating pressure than the coolant. Therefore, a porous pipe is required in the second pipe 230 to meet the refrigerant's pressure requirements. The porous pipe can be a folded porous pipe or an extruded porous pipe.

[0035] The distance between adjacent first tubes 130 is different from the distance between adjacent second tubes 230. The first heat exchanger 100 and the second heat exchanger 200 require different heat exchange efficiencies, and the different distances between adjacent first tubes 130 and adjacent second tubes 230 can satisfy these different heat exchange efficiencies. Of course, when the heat exchange efficiency requirements of the first heat exchanger 100 and the second heat exchanger 200 are not very high, the distances between adjacent first tubes 130 and adjacent second tubes 230 can also be set to be the same, which can reduce process complexity and cost.

[0036] In some embodiments, such as Figure 2 As shown, the heat exchange assembly 1000 also includes a side plate 400, which is connected to a portion of the plurality of fins 300. The side plate 400 is located on one side of the plurality of first tubes 130 and the plurality of second tubes 230. That is, the first heat exchanger 100 and the second heat exchanger 200 share the side plate 400. The side plate 400 strengthens the connection between the first heat exchanger 100 and the second heat exchanger 200 by connecting with the plurality of first tubes 130 and the plurality of second tubes 230.

[0037] like Figure 7As shown, the side plate 400 includes a side plate body 410 and a baffle portion 420. A first portion of the side plate body 410 is connected to a plurality of first pipes 130, and a second portion of the side plate body 410 is connected to a plurality of second pipes 230. The baffle portion 420 is connected to one end of the side plate body 410 near the first current collector 110, and extends towards the first pipes 130 and the second pipes 230. The baffle portion 420 can protect the outermost first pipes 130 and second pipes 230, isolating them from the outside.

[0038] During the welding process of the heat exchange assembly 1000, the first collector core 110, the first weld layer 120 and multiple first tubes 130, the second collector core 210, the second weld layer 220 and multiple second tubes 230 are first assembled. Then, the first weld layer 120 and the second weld layer 220 are melted simultaneously. After the first weld layer 120 and the second weld layer 220 solidify, the heat exchange assembly 1000 is welded together. In this way, the first heat exchanger 100 and the second heat exchanger 200 can be welded together in a single welding process, realizing the integration of the first heat exchanger 100 and the second heat exchanger 200, reducing process steps and lowering process costs.

[0039] In this application, the "connection" between two components can be a direct connection or a connection via a pipeline. The two components may only have a pipeline between them, or they may have a valve or other component in addition to a pipeline. Similarly, the "connection" between two components in this application can be a direct connection or a connection via a pipeline. The two components may only have a pipeline connection, or they may have a valve or other component in addition to a pipeline connection.

Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application.
