In this way, the flow guide 118 is fixed or limited, and the processing and manufacturing of the integrated assembly 100 are facilitated.

[0035] Further, refer to Figures 3 to 7As shown, as an implementation manner, the flow guide 118 comprises a lug portion 121 and a body portion 1182, the lug portion 121 is fixedly connected with the body portion 1182 or the lug portion 121 and the body portion 1182 are an integral structure, the first flow channel plate 116 comprises a recessed portion 122, the lug portion 121 is fixedly connected or positionally connected with the recessed portion 122, and the body portion 1182 is located in the inner recessed groove 1161. First, the lug portion 121 is formed on the flow guide 118, which is conducive to improving the structural strength of the flow guide 118. Second, the weight of the flow guide 118 can be appropriately increased, and the flow guide 118 can be selected to be made of a material with a lower cost than the material of the first flow channel plate 116, so that the production cost of the integrated assembly 100 is further reduced.

[0036] Specifically, as an implementation manner, referring to Figures 3 to 7 As shown, the body portion 1182 comprises an outer wall portion 1182a, the outer wall portion 1182a is gap-fitted with the wall portion corresponding to the inner recessed groove 1161, the recessed portion 122 is inwardly recessed from the wall portion corresponding to the inner recessed groove 1161, the lug portion 121 is outwardly protruded from the outer wall portion 1182a, and the lug portion 121 is positionally connected or fixedly connected with the recessed portion 122.

For example, the fixed connection between the flow guide 118 and the second flow channel plate 117 can be achieved at the same time as the welding of the first flow channel plate 116 and the second flow channel plate 117. In this way, while increasing the connection strength between the flow guide 118 and the second flow channel plate 117, it is beneficial to simplify the manufacturing steps of the integrated assembly 100.

Further, the supporting portion 1212 protrudes from the end surface 1181, and the supporting portion 1212 can be flush with the first welding surface 1162. It can be understood that the supporting portion 1212 is closer to the second flow channel plate 117 than the end surface 1181, and only the supporting portion 1212 is welded and fixed with the second flow channel plate 117 when the first flow channel plate 116 and the second flow channel plate 117 are welded. In this way, it is beneficial to reduce the manufacturing difficulty of the integrated assembly 100.

[0038] As a specific embodiment, please refer to Figures 1 to 12 As shown, the integrated assembly 100 comprises an interface portion 113, the interface portion 113 has an interface cavity 1131, the integrated assembly 100 comprises a flow channel cavity 112, the interface cavity 1131 communicates with the flow channel cavity 112, and the flow guide 118 is arranged upstream of the interface portion 113.

In this way, it is beneficial to reduce the manufacturing difficulty of the integrated assembly 100.

[0039] Please refer to Figures 8 to 9As shown, the number of flow guides 118 can be multiple, which can be adapted according to the structure of the flow channel cavity 112 of the integrated assembly 100. Specifically, as another implementation manner, the integrated assembly 100 comprises a mounting portion 1164 having an outlet 1164b and an inlet 1164c, the integrated assembly 100 comprises an electric pump 1141 installed on the mounting portion 1164, the electric pump 1141 comprises a pump inlet 1141a and a pump outlet 1141b, the pump inlet 1141a is in communication with the inlet 1164c, the pump outlet 1141b is in communication with the outlet 1164b, and the flow guide 118 is arranged downstream of the outlet 1164b.

The number of flow guides 118 can be matched with the number of electric pumps. In the embodiment, the number of electric pumps is 3, and the number of flow guides 118 is also 3.

[0040] Further, as an implementation manner, please refer to Figures 8 to 11 As shown, the flow guide 118 comprises a first surface 1183, which is away from the second flow channel plate 117 along the thickness direction of the flow guide 118, and extends along the direction of the working medium flow. The integrated assembly 100 comprises a flow channel cavity 112, which comprises a first channel 1121 downstream of the pump outlet 1141b, and the wall portion forming the first channel 1121 comprises the first surface 1183 of the flow guide 118. The flow area of the starting end of the first channel 1121 is greater than that of the pump outlet 1141b, and the flow area of the first channel 1121 gradually increases along the flow direction of the cooling liquid. In this way, it is beneficial to reduce the noise of the integrated assembly 100. Please refer to Figure 11 As shown, S1 is the path of the cooling liquid flow.

[0041] Further, as an implementation manner, please refer to Figures 8 to 11 As shown, the flow cross section of the first channel 1121 comprises a width and a height, and the height gradually increases along the flow direction of the cooling liquid in the first channel 1121.

[0042] To further reduce the cost of the integrated assembly 100, please refer to Figures 8 to 11 As shown, the flow cross-sectional area of the first channel 1121 can be adaptively adjusted according to the cross-sectional area of the pump outlet 1141b, that is, for a water pump with a larger power, the flow cross-sectional area of the pump outlet 1141b changes, the size value in the thickness direction of the flow guide piece 118 can be changed to adaptively adjust the flow cross-sectional area of the first channel 1121. In this way, the integrated assembly 100 can be matched with electric pumps 1141 of different powers, which is conducive to increasing the adaptability of the flow channel integrated part 11 to water pumps of different powers. For example, for a water pump with a large power, the size value in the thickness direction of the flow guide piece 118 can be reduced to increase the size value in the height direction of the flow cross-sectional area of the first channel 1121. For a water pump with a small power, the size value in the thickness direction of the flow guide piece 118 can be increased to reduce the value of the flow cross-sectional area of the first channel 1121.

[0043] The position of the flow guide piece 118 can be set according to the requirements of the specific integrated assembly 100 and the flow channel cavity 112.
