Thermal management system for electrical components

Abstract

The invention relates to a thermal management system (200) for an electrical component, which system is capable of radiating heat during operation of the electrical component, in particular for an electrical energy storage module, comprising: at least one housing (2) for accommodating at least one electrical component, in particular a plurality of such housings arranged in parallel; at least one heat exchange plate (210) extending over at least part of the surface of the side of the housing, the at least one plate comprising at least one heat transfer fluid channel between a fluid inlet (211) and a fluid outlet (212) of the plate (210); a supply conduit configured to supply the heat transfer fluid to the plate via the fluid inlet of the plate and a discharge conduit configured to discharge the heat transfer fluid from the plate via the fluid outlet of the plate; a housing (300) defining a housing and housing the heat exchange plates and the supply and discharge conduits; a fluid collection tank (215) arranged to collect any fluid that may leak from the junctions between the fluid inlet and fluid outlet of the plate and the associated supply and discharge conduits so as to prevent said leaked fluid from falling into the bottom of the housing.

Description

technical field [0001] The present invention relates to a thermal management system for electrical components that tend to dissipate heat during operation. The thermal management system of the present invention is particularly suitable for cooling or heating electrical energy storage devices, especially for equipping the batteries of motor vehicles. Background technique [0002] Electronic components, whether they are electrical energy storage batteries, integrated circuits, servers, data centers, etc., require thermal regulation in order to keep them within their operating temperature range. [0003] For example, in the automotive field, it is known to use batteries in the form of electronic modules that tend to dissipate heat during operation. Each module may have a plurality of electronic batteries housed in the housing and liable to dissipate heat during operation. High-density energy storage batteries such as lithium-ion batteries ideally need to work in the temperatu...

Problems solved by technology

However, certain battery pack configurations and the increased exchange surface area between the battery cells and the cooling exchangers lead to an increased number of heat exchangers within the battery pack and thus multiple connections between the pipes supplying this liquid and the cooling exchangers
