Battery liquid cooling plate assembly, battery assembly and vehicle

Abstract

The invention discloses a battery liquid cooling plate assembly, a battery assembly and a vehicle, and belongs to the field of battery safety, the battery liquid cooling plate assembly comprises a liquid cooling plate upper plate, a liquid cooling plate lower plate and a cooling liquid joint, a cooling flow channel is formed between the liquid cooling plate upper plate and the liquid cooling plate lower plate, the liquid cooling plate lower plate is provided with a plurality of cooling grooves; a plurality of openings are correspondingly formed in the liquid cooling plate upper plate, the plurality of openings and the plurality of grooves are arranged in a one-to-one correspondence manner, and the battery modules are partially fixed in the cooling grooves through the openings and are in sealed connection with the liquid cooling plate upper plate; at least one circulating hole is formed in the groove wall of each cooling groove, and the multiple cooling grooves are communicated through the circulating holes; the cooling liquid joint is arranged on the liquid cooling plate upper plate and communicated with the cooling flow channel, and the cooling groove located in one side of the cooling liquid joint is communicated with the cooling flow channel. The battery liquid cooling plate assembly is simple in manufacturing process, low in requirement for arrangement space and high in applicability, semi-immersed cooling of the battery module is achieved, and heat management of the battery module can be effectively achieved.

Description

technical field [0001] The invention relates to the technical field of battery safety, in particular to a battery liquid cold plate assembly, a battery assembly and a vehicle. Background technique [0002] New energy vehicles have the advantages of high energy efficiency, zero emissions, no pollution, high specific energy, low noise, and high reliability. As the main energy storage component of the new energy battery vehicle, the power battery assembly mainly ensures the low-speed driving of the vehicle, braking energy recovery, energy regulation of the hybrid engine system and other functions. As the core component of battery assembly structure protection and fixation, the importance of battery assembly is self-evident. As the main component of the power battery thermal management system, the liquid cold plate undertakes the functions of cooling, heating, and temperature equalization of the battery. [0003] The existing liquid cold plate solution does not realize the mod...
