Abstract

The invention provides a novel liquid cooling plate, relates to the technical field of batteries, and solves the technical problem of relatively poor heat exchange uniformity of a liquid cooling platein the prior art. The liquid cooling plate comprises an internal flow channel, a liquid inlet is formed in the bottom of the internal flow channel, a liquid outlet is formed in the top of the internal flow channel, and cooling liquid flowing in from the liquid inlet can be discharged from the liquid outlet after passing through the latticed internal flow channel. The novel liquid cooling plate isused for cooling the battery, and the temperature uniformity of the power battery is ensured as much as possible.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a novel liquid cold plate. Background technique [0002] The working performance of the electric vehicle power battery is seriously affected by the temperature. In order to ensure the working performance of the power battery, the battery is required to be at a suitable temperature. The working environment temperature of the power battery is currently -30°C ~ 55°C, and the ideal working temperature of the battery is between 15°C ~ 30°C, the traditional air cooling and natural cooling cannot meet the conditions and requirements of its use, it is necessary to apply liquid cold technique. [0003] Liquid cold plate is the most common way of liquid cooling technology. In the design of the liquid cold plate, flow uniformity and heat exchange efficiency are two very important aspects, especially flow uniformity, which will affect the heat exchange uniformity, and then affect the tem...
