The invention discloses a power battery integrated liquid cooling box, which comprises a base and an enclosing frame, wherein the base comprises a chassis fixed on a vehicle body and a flow channel integration plate paved above the chassis and fixed on the chassis, flow channels are cyclically arranged in the flow channel integration plate, the enclosing frame is fixed above the base, and is matched with the base to form an accommodating cavity for placing a power battery, the side wall of the enclosing frame is provided with high-low voltage communication installation ports, a fuse installation port, water inlets and water outlets, and the water inlets and the water outlets are communicated to the flow channels. According to the present invention, through the integrated design of the liquid cooling system and the box, the assembly of the liquid cooling system part is eliminated so as to reduce the risk of leakage, and the cooling liquid cannot leak into the box during the failure so as to ensure the use safety of the power battery; and the power battery integrated liquid cooling box has advantages of reasonable structure design, high integration and small occupation space.
Description
technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to an integrated liquid cooling box for a power battery. Background technique [0002] With the development of new energy vehicles, the safety and reliability of power batteries are becoming more and more important. As the power source of new energy vehicles, the power battery system must design a reasonable thermal management system in order to ensure its efficient and reliable operation. As a widely used thermal management system, the liquid cooling system has the characteristics of high heat exchange efficiency and easy temperature control. There is a high risk of leakage in the middle, and once leakage will seriously affect the safe use of the power battery. SUMMARY OF THE INVENTION [0003] Based on the technical problems existing in the above background technology, the present invention proposes an integrated liquid cooling box for a power battery. [0004] T...
