DETAILED DESCRIPTION

[0029] With the rapid development of electric vehicles, the automotive industry is coupling various thermal management subsystems to save energy and space, forming highly integrated thermal management modules. Thermal management integrated modules are mainly divided into refrigerant-side integrated modules, water-side integrated modules, and the coupling of the two. Currently, the refrigerant-side integrated module uses cast aluminum to form the internal flow channel. Joints are provided on the cast aluminum flow channel plate, sealed with O-rings or sealing gaskets, and bolted to the heat exchanger 120. This approach has the following problems:

[0030] High cost: Mold costs are high. To ensure airtightness, the heat exchanger 120 requires high assembly position and mold processing precision. The heat exchanger 120 and the flow channel plate are sealed with O-rings or sealing sheets. The roughness of the joints of the two products must be guaranteed, so high processing precision is required, which increases costs. The one-piece cast aluminum needs to be installed with other module components and the entire vehicle, so the connection parts must be strong, heavy, and costly.

[0031] The process is complicated: the heat exchanger 120 is sealed by an O-ring or a sealing sheet. During assembly, the O-ring or sealing sheet needs to be installed on the joint, lubricated, press-fitted, and tightened with bolts;

[0032] High leakage risk: There is a risk of sealing in all sealing parts, and problems in component processing and assembly processes may lead to substandard finished products;

[0033] Limitations: Cast aluminum materials have limitations, and special die-cast aluminum materials must be selected (the Si and Mg element content must be controlled at a low level). Therefore, brazing cannot be used, and the remaining components must be sealed by O-rings or sealing gaskets.

[0034] In response to the above problems, the present invention provides a refrigerant integrated module 100, which adopts a split structure to manufacture the refrigerant flow plate 110, so that the refrigerant flow plate 110 can form a refrigerant flow path through two or more parts processed by aluminum stamping or cutting, which is beneficial to reducing the processing cost of the refrigerant integrated module 100, and such a structural setting method is beneficial to reducing the structural weight, and is convenient for connection with the heat exchanger 120 or other components when installed in the whole vehicle; and during installation, compared with the connection and sealing method through sealing rings and connecting bolts in the prior art, due to the structural changes of the refrigerant flow plate 110, welding can be used for installation and connection, thereby improving the stability of the seal, reducing the connection and sealing parts of the refrigerant flow plate 110 and the heat exchanger 120, and less assembly, and reducing the process cost.

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0039] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0040] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0041] Please refer to Figure 1 and Figure 2 , this embodiment provides a refrigerant integrated module 100, the refrigerant integrated module 100 includes a refrigerant flow channel plate 110 and a heat exchanger 120;

[0042] The refrigerant flow channel plate 110 includes a first section 111 and a second section 112 . The first section 111 and the second section 112 are connected to form a refrigerant flow channel.

[0043] The heat exchanger 120 is connected to the first sub-portion 111 or the second sub-portion 112 and communicates with the refrigerant flow channel.

[0044] It should be noted that such a setting method allows the refrigerant flow channel plate 110 to be made of weldable materials, and then when assembled with the heat exchanger 120, the sealing method and connection method between the two can be changed to one-piece brazing, thereby effectively solving the problems of high cost, heavy weight, high leakage rate, and low qualified rate of sealing joints.

[0045] Please refer to Figure 1 and Figure 2The refrigerant integrated module 100 includes a refrigerant flow channel plate 110 and a heat exchanger 120; the refrigerant flow channel plate 110 adopts a split structure, so that the refrigerant flow channel plate 110 can be formed into two or more parts through aluminum stamping or cutting, which is beneficial to reducing the processing cost of the refrigerant integrated module 100, and such a structural setting method is beneficial to reducing the structural weight, and is convenient for connection with the heat exchanger 120 or other components when installed in the whole vehicle; and during installation, the heat exchanger 120 is connected to the refrigerant flow channel plate 110 by welding, and then compared with the connection and sealing method of the heat exchanger 120 to the refrigerant flow channel plate 110 by a sealing ring and connecting bolts in the prior art, due to the structural change of the refrigerant flow channel plate 110, it can be installed and connected by welding, thereby improving the stability of the seal, reducing the parts for connecting and sealing the refrigerant flow channel plate 110 and the heat exchanger 120, and less assembly, and reducing the process cost.

[0046] Further, please refer to Figure 1-Figure 7 In this embodiment, when configuring the refrigerant flow channel plate 110, since it is made in a split manner, based on this method, the first division 111 and the second division 112 can be made by stamping to reduce the production cost, and on the basis of stamping, the corresponding molded refrigerant flow channel structure can be formed in the first division 111 and the second division 112; specifically, the first division 111 and the second division 112 are respectively provided with a first refrigerant flow groove 113 and a second refrigerant flow groove 114 with a semicircular cross-section, and the first refrigerant flow groove 113 and the second refrigerant flow groove 114 extend along the same curved path to jointly form the refrigerant flow channel after the first division 111 and the second division 112 are connected.

[0047] In addition, based on the above structure, the heat exchanger 120 is connected to the refrigerant flow plate 110 by welding. Therefore, the heat exchanger 120 can be connected to the first division 111 by welding. Based on this, the first division 111 is configured with a first refrigerant inlet 115 and a first refrigerant outlet 116, and the first refrigerant inlet 115 is separated from the first refrigerant outlet 116; and the heat exchanger 120 is configured with a second refrigerant inlet 121 and a second refrigerant outlet 122; the first refrigerant inlet 115 is connected to the second refrigerant outlet 122, and the second refrigerant inlet 121 is connected to the first refrigerant outlet 116.

[0048] Further, please refer to Figure 1-Figure 7In this embodiment, to facilitate connection of the heat exchanger 120 to the first subsection 111, a first connecting portion 117 and a second connecting portion 118 are protruded from the first subsection 111 in a direction away from the second subsection 112. The first connecting portion 117 is spaced apart from the second connecting portion 118, and both the first connecting portion 117 and the second connecting portion 118 are connected to the heat exchanger 120. This arrangement facilitates welding the heat exchanger 120 to the first connecting portion 117 and the second connecting portion 118 by providing the protruding first connecting portion 117 and the second connecting portion 118 on the first subsection 111, thereby reducing the difficulty of welding.

[0049] Based on the structure of the first connecting portion 117 and the second connecting portion 118 described above, this embodiment adopts a method in which the first refrigerant inlet 115 is opened at the first connecting portion 117, and the first refrigerant outlet 116 is opened at the second connecting portion 118. Therefore, in this way, when the heat exchanger 120 and the first subsection 111 are welded together, the heat exchanger 120 can be connected to the first refrigerant inlet 115 and the first refrigerant outlet 116 on the first subsection 111. That is, the connection and connection steps can be combined, thereby simplifying the connection and connection manufacturing steps and reducing the installation cost.

[0050] Thus, the refrigerant integrated module 100 adopts the above-mentioned structural arrangement, so that the refrigerant flow channel plate 110 can be selected from weldable stamped aluminum or cut aluminum; and on this basis, the refrigerant flow channel plate 110 is formed of two or more parts processed by stamping or cutting aluminum to form a flow path;

[0051] Furthermore, compared with the connection and sealing method in the prior art in which the heat exchanger 120 is connected to the refrigerant flow channel plate 110 by a sealing ring and connecting bolts, the refrigerant integrated module 100 can be connected by brazing components, and the flow channel plate is also brazed with stacked heat exchanger 120 products such as water-cooled capacitors or coolers; in addition, the refrigerant flow channel plate 110 and the heat exchanger 120 are welded together by riveting, and then radially welded to form a seal, or the refrigerant flow channel plate 110 and the heat exchanger 120 are in plane contact through process positioning, and a seal is formed after welding their end faces, etc.; the heat exchanger 120 eliminates the bottom plate, and the core itself is welded integrally with the refrigerant flow channel plate 110; therefore, the refrigerant integrated module 100 can be installed and connected by welding, thereby improving the stability of the seal, reducing the components for connecting and sealing the refrigerant flow channel plate 110 and the heat exchanger 120, and less assembly, and reducing process costs.

[0052] Based on the above, please refer to Figures 1-8In this embodiment, the heat exchanger 120 is welded to the refrigerant channel plate 110. Based on the above structure, there are multiple connection methods when welding the first connection portion 117 and the second connection portion 118 to the heat exchanger 120, such as:

[0053] The refrigerant flow channel plate 110 and the heat exchanger 120 are in plane contact and positioned by a process, and a sealing is formed after welding their end faces, which is not limited to welding methods. Specifically, the first connecting portion 117 and the second connecting portion 118 are both in contact with the heat exchanger 120, and the end faces of the first connecting portion 117 and the second connecting portion 118 are both welded to the heat exchanger 120. In other words, the end faces of the first connecting portion 117 and the second connecting portion 118 can be welded to the heat exchanger 120.

[0054] In addition, the refrigerant flow channel plate 110 and the heat exchanger 120 can also be welded together by riveting and then radially welded to form a seal. Specifically, the second refrigerant inlet 121 and the second refrigerant outlet 122 are both protruding from the bottom of the core of the heat exchanger 120, and the second refrigerant inlet 121 extends into the first refrigerant outlet 116, and the second refrigerant outlet 122 extends into the first refrigerant inlet 115 (such as Figure 8 As shown). And on this basis, make welding connection;

[0055] Based on the aforementioned arrangement that the second refrigerant inlet 121 extends into the first refrigerant outlet 116 and the second refrigerant outlet 122 extends into the first refrigerant inlet 115, the second refrigerant inlet 121 is riveted to the first refrigerant outlet 116, and the second refrigerant outlet 122 is riveted to the first refrigerant inlet 115; the portion of the second refrigerant inlet 121 extending into the first refrigerant outlet 116 is welded to the first refrigerant outlet 116, and the portion of the second refrigerant outlet 122 extending into the first refrigerant inlet 115 is welded to the first refrigerant inlet 115. In this way, the stability and sealing of the connection can be improved based on both riveting and welding connection methods.

[0056] In summary, based on the above-mentioned refrigerant integrated module 100, this embodiment further provides an electric vehicle, which includes the above-mentioned refrigerant integrated module 100. By adopting the above-mentioned refrigerant integrated module 100, the electric vehicle can reduce costs and reduce leakage risks.

[0057] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
