Abstract

The invention provides an immersion cooling power battery pack, an immersion cooling method and a vehicle. The power battery pack includes a battery box, and a plurality of beams are arranged side by side in the battery box, and the beams connect the inner space of the battery box. It is divided into several accommodating cavities, and battery modules are arranged in the accommodating cavities; the side wall of the battery box is surrounded by two relatively parallel first side walls and two relatively parallel second side walls, so The beam and the second side wall are parallel to each other; a gap is left between the two ends of the beam and the first side walls on both sides, and a first flow channel and a second flow channel are formed along the two first side walls; A liquid inlet close to the first flow channel and a liquid outlet close to the second flow channel are respectively provided on each of the second side walls. Compared with liquid cooling, the immersion cooling system proposed by the present invention has a shorter heat transfer path, larger cooling area and higher cooling efficiency, and can exert better cooling effects from the perspective of thermal management and thermal runaway.

Description

technical field [0001] The invention belongs to the technical field of power batteries, and relates to an immersion cooling power battery pack, an immersion cooling method and a vehicle. Background technique [0002] As the main source of power for electric vehicles, power batteries have been rapidly applied and developed. The overall performance of the power battery is significantly affected by temperature. When the temperature is high, the active material of the battery is enhanced, and an irreversible chemical reaction may occur, causing thermal runaway and causing the vehicle to catch fire and explode. When the temperature difference is large, a local hot zone will be formed, and the high temperature will decay too quickly , resulting in reduced battery cycle life. Therefore, effective control of battery temperature for reasonable heat exchange is the main focus of battery thermal management system design. [0003] At present, air, liquid or phase change materials are ...
