The water circuit board 2 is directly integrated with the water outlet end cover features of the first pump body 8 and the second pump body 10, and the interiors of the two end cover features are directly connected with the second pipeline 12 and the fourth pipeline 14, respectively, as the water outlets of the two water pumps. The first pump body 8 and the second pump body 10 are directly connected with the end cover features of the water circuit board 2, that is, the end covers of the first pump body 8 and the second pump body 10 are directly arranged on the water circuit board 2, reducing the size of the water circuit side module in the axial direction of the pump body.

In the present application, three fifth pipelines 15 are used, and the three fifth pipelines 15 are communicated with other water pipes through intermediate pipelines to each thermal management object on the vehicle. Figure 2 As shown in combination with FIG. 1, when the refrigerant flow path board 1 and the water circuit board 2 are embedded and installed, the three fifth pipelines 15 can pass through the hollow between the two heat exchangers without affecting the assembly, and when the length of the three fifth pipelines 15 does not exceed the thickness of the heat exchanger, the thickness of the entire thermal management module will not be additionally increased.

[0043] It should be noted that the management object needing heating and the management object needing heat dissipation are not fixed, and can be converted according to different external temperatures and use scenes. For example, the power battery of the automobile, when the external temperature is low and the heat generation of the battery itself is small, it is a management object needing heating;When the temperature is high or the heat generation is large, it is a management object needing heat dissipation. The heat management flow path control of various heat management objects under different temperature, scene and other use conditions is realized through the multi-way valve.

[0049] Those skilled in the art can understand that the advantageous technical features of the above-mentioned modes can be freely combined and superimposed without conflict.

[0050] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model. The above only describes the preferred embodiments of the utility model, and it should be pointed out that, for ordinary skilled in the art, without departing from the technical principle of the utility model, a plurality of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the utility model.
