Abstract

The invention relates to a chassis cooling system for a battery pack. The chassis cooling system comprises a chassis shell which opens upwards and a plurality of battery pack separating plates. A plurality of sliding grooves are formed in the inner side wall of the chassis shell, and the battery pack separating plates are embedded into the sliding grooves. A liquid storage cavity filled with negative thermal expansion materials is formed in each battery pack separating plate, and a water inlet channel and a water outlet channel which both communicate with the liquid storage cavity are also formed in each battery pack separating plate. A cooling cavity and ducts communicating with the water inlet channels and the water outlet channels are formed in the chassis shell, the cooling cavity communicates with the ducts communicating with the water inlet channel and the water outlet channel to form a cooling liquid passage, and the cooling cavity is filled with air bags.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a battery pack chassis cooling system. Background technique [0002] At present, the cooling methods widely used in new energy vehicle battery packs mainly include air cooling and water cooling. The heat dissipation system of new energy vehicles currently adopting air-cooling mode adds fans, windshields and other devices. The heat dissipation capacity of the air-cooled heat dissipation system in the prior art is proportional to the volume, and the heat dissipation capacity of the air-cooled heat dissipation system is limited and the efficiency is low. ; It is easy to generate vibration, and it is difficult to apply to occasions with high heat dissipation pressure and limited space. [0003] At present, the new energy vehicles that use water cooling to cool the battery pack in the prior art have the following problems: 1) The layout of each component is too scattered and not co...
