Description

Technical Field

[0001] The present application relates to the field of thermal management technology, and in particular to a thermal management device. Background Art

[0002] A thermal management device is a heat exchange device used to exchange heat for a device or component, such as a battery or a charging station.

[0003] In the related art, the thermal management device includes a first flow channel plate, a valve assembly, a pump assembly, a first heat exchanger, and a second heat exchanger. The valve assembly, the pump assembly, the first heat exchanger, and the second heat exchanger are all connected to the first flow channel plate. The first heat exchanger and the second heat exchanger are both located on the same side of the valve assembly, and the pump assembly and the first heat exchanger are respectively located on different sides of the valve assembly. The first heat exchanger is closer to the pump assembly than the second heat exchanger. Since the first heat exchanger is closer to the pump assembly than the second heat exchanger, the distance between the pump assembly and the second heat exchanger is far, which will increase the flow resistance between the pump assembly and the second heat exchanger. Summary of the invention

[0004] The object of the present application is to provide a thermal management device, comprising a first flow channel plate, a valve assembly, a pump assembly, a first heat exchanger and a second heat exchanger, wherein the valve assembly, the pump assembly, the first heat exchanger and the second heat exchanger are all connected to the first flow channel plate;

[0005] The first heat exchanger, the second heat exchanger and the pump assembly are arranged along the circumference of the valve assembly, and the pump assembly is at least partially located between the first heat exchanger and the second heat exchanger in a direction perpendicular to the thickness direction of the first flow channel plate.

[0006] In the present application, the first heat exchanger, the second heat exchanger and the pump assembly are all located on the peripheral side of the valve assembly. Along the direction perpendicular to the thickness direction of the first flow channel plate, the pump assembly is at least partially located between the first heat exchanger and the second heat exchanger, thereby reducing the distance between the pump assembly and the second heat exchanger and reducing the flow resistance between the pump assembly and the second heat exchanger.
