[0029] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0033] The present application provides a refrigerant side integrated flow channel plate, referring to Figure 1 and Figure 2 The refrigerant side integrated flow channel plate includes a main flow channel plate 1 and a plurality of welding plates. The main flow channel plate 1 is provided with welding seats corresponding to the welding plates. The welding plates are welded to the corresponding welding seats by welding, thereby sealing them. After welding, the area inside the main flow channel plate 1 is sealed. Such a small area welding method has low cost, avoids technical problems such as large deformation of large area welding, and has high reliability.

[0034] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the welding plates include a first welding plate 21, a second welding plate 22, a third welding plate 23, a fourth welding plate 24, a fifth welding plate 25 and a sixth welding plate 26. Figure 3 and Figure 4 The corresponding welding seats are the first welding seat 111, the second welding seat 112, the third welding seat 113, the fourth welding seat 114, the fifth welding seat 115 and the sixth welding seat 116. Figure 5 and Figure 6 , there are corner structures in the third welding seat 113 and the sixth welding seat 116. In order to reduce the flow resistance therein, the corner structures are configured as rounded structures. In other embodiments, the number and position of the welding plates and welding seats can be specifically set according to design requirements, and this application does not limit them.

[0035] Reference Figure 1 The main channel plate 1 is provided with a plurality of channels, and different channels can be parallel to each other or cross each other for the circulation of refrigerant. The channels are mainly made of straight tubes and are manufactured by die-casting core pulling. After the die-casting core pulling is completed, the plug of the channel is also sealed by a local welding process. Compared with the multi-thread plus sealing ring plug method commonly used in the prior art, it has lower cost and occupies less space. The die-casting production process is adopted, so that the average wall thickness of the channel is smaller, and thus the mass of the main channel plate 1 in the embodiment of the present application is smaller.

[0036] Furthermore, on the main channel plate 1, heat insulation grooves are provided between adjacent channels, thereby reducing the metal contact area between different channels, which can effectively reduce the harmful heat transfer between high-temperature refrigerant and low-temperature refrigerant under different working modes. Figure 3The thermal insulation grooves include thermal insulation groove 121, thermal insulation groove 2 122, thermal insulation groove 3 123, thermal insulation groove 4 124 and thermal insulation groove 5 125. In other embodiments, the thermal insulation grooves can be specifically arranged according to the positions of the flow channels, which is not limited in the present application.

[0037] The main channel plate 1 is also provided with a number of external interfaces, each of which is connected to at least one channel. The external interfaces include equipment external interfaces and parts installation interfaces, wherein the equipment external interfaces are used to connect circulation equipment, such as compressors, heat exchangers, etc., to form a refrigerant circulation loop for the whole vehicle. The parts installation interface is used for external refrigerant side parts, such as expansion valves, stop valves, one-way valves, battery coolers, gas-liquid separators, sensors, etc. The above design has a high degree of integration, so that the main channel plate 1 occupies a small space and is light in weight.

[0038] Reference Figure 3 and Figure 4 In the embodiment of the present application, the device external interface includes device external interface 1 131, device external interface 2 132, device external interface 3 133, device external interface 4 134 and device external interface 5 135. The parts installation interface includes small expansion valve 1 installation interface 141, temperature sensor installation interface 142, pressure sensor installation interface 143, stop valve 1 installation interface 144, small expansion valve 2 installation interface 145, battery cooler refrigerant inlet installation interface 146, battery cooler refrigerant outlet installation interface 147, large expansion valve installation interface 148, stop valve 2 installation interface 149, gas-liquid separator inlet installation interface 1410 and check valve installation interface 1411. In other embodiments, the number and type of parts installation interfaces can be specifically set according to design requirements, and this application does not limit them.

[0039] Further, the part mounting interface includes a first part mounting interface and a corresponding second part mounting interface, and the first part mounting interface and the corresponding second part mounting interface are respectively used to connect parts having a parallel relationship. The first part mounting interface and the corresponding second part mounting interface are located on the same flow channel, and the center of the first part mounting interface or the corresponding second part mounting interface deviates from the center line of the flow channel.

[0040] Reference Figure 7In the embodiment of the present application, the first component installation interface mentioned above includes a stop valve installation interface 144, and the corresponding second component installation interface includes a large expansion valve installation interface 148. The stop valve 1 and the large expansion valve used for communication are in parallel in the topological principle diagram. The stop valve 1 installation interface 144 and the large expansion valve installation interface 148 are located on the same flow channel, and the center of the stop valve 1 installation interface 144 deviates from the center line of the flow channel. In actual use, the refrigerant flowing through the stop valve 1 installation interface 144 can flow directly into the stop valve 1 from the side, or flow to the large expansion valve installation interface 148 after passing around the stop valve 1 installation interface 144. Since the stop valve 1 installation interface 144 and the large expansion valve installation interface 148 are located on the same straight flow channel, the length of the pipeline is reduced, making the arrangement of the parts more compact and reasonable. At the same time, since the center of the stop valve 1 installation interface 144 deviates from the center line of the flow channel, the bypass design can effectively reduce the flow resistance of the flow channel.

[0041] Furthermore, the first part installation interface, the second part installation interface and the flow channel in which they are located can be made by die-casting core pulling or machining, and the processing difficulty is low.

[0042] The embodiment of the present application discloses a refrigerant-side integrated flow channel plate, which is provided with a main flow channel plate 1 and a welding plate, and a welding seat corresponding to the welding plate is provided on the main flow channel plate 1, and the sealing of the main flow channel plate 1 is achieved by welding the welding plate and the welding seat. Such a small-area welding method has low cost, avoids technical problems such as large deformation of large-area welding, and has high reliability. At the same time, the main flow channel plate 1 is also integrated with an external device interface and a part installation interface, and the design has a high degree of integration, so that the main flow channel plate 1 occupies a small space and is light in weight. In addition, for parts in a parallel relationship, corresponding first part installation interfaces and second part installation interfaces are also designed, and the flow resistance of the corresponding flow channel is reduced by the bypass design.

[0043] The embodiment of the present application also discloses a thermal management module, including a refrigerant side component and a water side component connected to the refrigerant side component, wherein the refrigerant side component is configured with a refrigeration side integrated flow channel plate as disclosed in the above embodiment.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection created by this application.
