BATTERY APPARATUS COMPRISING HEAT EXCHANGE ASSEMBLY AND ELECTRIC VEHICLE COMPRISING THE BATTERY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/032265
Kind Code:
A1
Abstract:
The present utility model relates to the technical field of electric vehicles. Specifically provided are a battery apparatus comprising a heat exchange assembly and an electric vehicle comprising the battery apparatus, aiming to solve the problem of large space occupation after heat exchange assemblies are connected to refrigerant pipes caused by unreasonable designs of the heat exchange assemblies of existing power batteries. For this purpose, the heat exchange assembly of the present utility model comprises: a heat exchange plate, refrigerant channels being arranged in the heat exchange plate, and a side surface of the heat exchange plate being provided with refrigerant ports communicated with the refrigerant channels; and a flow collection structure, the flow collection structure being used for connecting to a refrigerant pipe and being arranged on the heat exchange plate, a mounting position of the flow collection structure corresponding to positions of the refrigerant ports, the flow collection structure and the heat exchange plate enclosing a flow collection chamber, the refrigerant ports being communicated with the flow collection chamber, and a refrigerant being circulated between the refrigerant channels and the refrigerant pipe by means of the flow collection chamber. The heat exchange assembly of the present utility model can reduce or even avoid an end protruding from the heat exchange plate, thereby reducing the size of the heat exchange assembly in the length direction of the heat exchange plate, and reducing the space occupancy rate.
