Battery cold plate water jacket

Abstract

The invention relates to a battery cold plate water jacket, which comprises a water jacket liquid inlet, water jacket flow channels, a water jacket liquid outlet, and a water jacket joint. The water jacket flow channels present two flat S shapes side by side. The tails of the two S-shaped water jacket flow channels are connected in series to form a continuous flow channel. The water jacket liquidinlet and the water jacket liquid outlet are distributed on the side of the cold plate water jacket, and on the two sides in the thickness direction of the cold plate water jacket. The water jacket liquid inlet and the water jacket liquid outlet are connected to the water jacket flow channels through the water jacket joint. A step is disposed at the water jacket joint and a chamfer is disposed atthe bottom of the step. The cross-sectional area of the entire water jacket flow channels remains the same. The water jacket liquid inlet and the water jacket liquid outlet are configured as 45-degreeelbows. Each section of the water jacket flow channels and the adjacent section have the same distance.

Description

technical field [0001] The invention relates to a battery cold plate water jacket. Background technique [0002] At present, with the increasingly prominent energy issues, energy saving and emission reduction has become one of the primary concerns of automobile companies, so more and more companies have begun to produce electric vehicles. The performance of electric vehicles is greatly affected by the power battery pack. At present, the energy density and power density of new energy power batteries are also increasing. The heating temperature of the battery needs to be paid attention to. On the one hand, the operating temperature of the battery pack has an impact on the performance of the battery. In addition, the overheating of the battery will also cause the risk of spontaneous combustion. Conventional natural air cooling and forced air cooling of batteries can no longer meet the needs of new energy use, so more and more power batteries are beginning to use liquid cooling...
