Abstract

The invention relates to a condenser (3) of a cooling device (2) of at least one battery element (103) of a motor vehicle, configured to liquefy a dielectric fluid deposited in the form of vapor at the surface of said condenser, characterized in that the condenser comprises at least one main wall (6) and a plurality of secondary walls projecting from the main wall and participating in forming a chamber for receiving one or more battery elements. The condenser comprises a cooling fluid circuit provided in the thickness of the main wall and at least one dielectric fluid circuit in liquid form provided in the thickness of at least one secondary wall, said electrical fluid circuit being equipped with at least one nozzle for projecting the dielectric fluid.

Description

technical field [0001] The present invention belongs to the field of thermal treatment devices for electrical storage systems of motor vehicles, and more specifically, the invention relates to a device for cooling battery components that get hot. The invention also relates to a method of using the cooling device. Background technique [0002] In the field of motor vehicles, heat treatment devices make it possible to modify the temperature of batteries, in particular to reduce the temperature of batteries, which tend to heat up when they are used. Generally, this type of heat treatment device for batteries uses a heat exchanger. In particular, the different battery cells of the electrical storage system can be cooled by means of a cooling plate, inside which a cooling fluid circulates, which is in contact with the battery cells to be cooled. It has been found that this type of heat exchanger leads to uneven cooling of the cells of an individual electrical storage system, le...
