Heat dissipation structure of power battery pack of new energy vehicle

Abstract

The invention provides a heat dissipation structure of a power battery pack of a new energy vehicle. The heat dissipation structure includes a liquid inlet, a vertical liquid cooling plate, a liquid cooling tube, a rectangular tray, a mounting base, a flow guiding pipe, a heat dissipation board, an air duct, an upper cover plate, a horizontal liquid cooling plate, a liquid outlet, and a heat conductive sheet. The horizontal liquid cooling plate is arranged on the inner bottom of the top end of the tray. The vertical liquid cooling plate is arranged on the top end of the horizontal liquid cooling plate in an integrated structure. By modifying the heat dissipation structure of the power battery pack of the new energy vehicle, a plurality of independent working zones are supplied to the battery module and effective circulating heat dissipation channels are supplied to the zones, so that temperature of the battery cells in the zones is consistent. The heat dissipation structure improves working efficiency of the battery module and prolongs service life of the power battery pack, thus effectively solving the problems and defects described in the background technologies.

Description

Technical field [0001] The invention relates to the technical field of heat dissipation structures for new energy vehicles, and more specifically, to a heat dissipation structure for power battery packs of new energy vehicles. Background technique [0002] The power battery module is a power source that connects several single batteries in series and parallel through conductive connectors, and is fixed in the design position through the process and structure, and cooperates with the function of charging and discharging electric energy. It can be said that the basic function of the module is to connect and fix And safety protection. [0003] With the increasingly prominent environmental problems, the development of new energy vehicles is getting faster and faster. As the core component of new energy vehicles, the development prospects of vehicle power battery modules are getting wider and wider, and the working temperature of power battery modules is too high. Or too low will reduc...
