Embodiment Construction
[0016] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0017] combine figure 1 , the present invention provides a power battery thermal management system based on the joint liquid cooling and heat dissipation of the tabs and the bottom of the battery cell. The battery pack is clamped by the liquid cooling plate on the top and bottom of the system, and the combination of multiple spatial dimensions is used for efficient liquid cooling and heat dissipation; isolation The thermally conductive filling glue provided in the frame increases the heat exchange contact area between the tab and the top liquid cooling plate. The present invention couples the heat management method of tab heat dissipation, which can greatly reduce the heat transfer resistance of the system, efficiently dissipate heat from the battery module, ensure that the power battery is in a suitable temperature range, and further improve the temperature unifo...
