Both ends of the battery pack heat exchange bags are connected to the heat exchange bag circulation pump through the heat exchange bag circulation pipeline. The heat exchange bag circulation pump is connected to one side of the transfer water tank. The heat exchange water tank is connected to the transfer water tank through the heat exchange circulation pipeline.

[0005] Based on the above technical solution, the battery pack heat exchange bag is composed of canvas tubes, knitted seam lines, double-ended circulation connector water pipes, and canvas tube pull-in rings. The canvas tubes are stacked, and the knitted seam lines are sewn to the edges of the canvas tubes. A water bag is provided on the canvas tube inside the knitted seam lines. The double-ended circulation connector water pipes are respectively located at both ends of the canvas tubes. Multiple sets of canvas tube pull-in rings are provided, and the multiple sets of canvas tube pull-in rings are respectively embedded in the side corners of both ends of the canvas tubes. A sealing layer is provided on the inner wall of the canvas tubes. The sealing layer on the inner wall of both ends of the canvas tubes is heat-fused and fixed. The water bag is connected to the heat exchange bag circulation pipeline through the double-ended circulation connector water pipes.

[0006] Compared with the prior art, the present invention has the following advantages: The present invention optimizes the setting of the cooling system of new energy vehicles, changes the traditional integrated design, and improves it into a split design battery pack heat dissipation system. The structure adopts a soft contact method to contact the battery pack, which is a more fitting design.
