U-shaped cooling module for electrical power equipment

Abstract

The invention relates to a cooling module (1) configured to cool at least one electrical module, the cooling module (1) comprising two fluid inlet / outlet apertures (12) and a cooling channel (11) formed in the cooling module (1). The cooling channel (11) has a U-shaped section forming two branches such that the cooling channel (11) ensures a U-shaped flow of the cooling fluid between the two fluid inlet / outlet apertures (12), the cooling module (1) comprising, between the two branches, at least one receptacle (13) adapted to allow a sealed insertion of the at least one electrical module, the at least one electrical module is thereby cooled by heat conduction.

Description

technical field [0001] The present invention relates to the field of cooling of electrical equipment, in particular for vehicles, in particular for electric or hybrid vehicles. More particularly, the present invention relates to cooling modules, especially for use in power electrical equipment, especially DC-DC voltage converters, chargers, or inverters. Background technique [0002] As is known, the power electrical device may comprise at least one power electronic module. It should be noted that the term "power electronic module" should be understood to refer to an assembly comprising components through which electrical energy flows. These components may include electronic switches, such as semiconductor transistors, arranged in the circuit so as to allow a controlled flow of electrical energy. In particular, the component is a bare semiconductor chip, for which a single body implements a packaging, eg a physical packaging. In other words, a power electronic module is a...

[0006] However, the bracket described by document US 2018219488 A1 comprises channels formed in the mass of the bracket configured to fluidly connect two cooling modules, making the production of such a bracket complex and expensive

In particular, the implementation of such supports involves expensive molding techniques, in particular gravity casting processes using cores, and involves carrying out extensive tests, in particular leak tests at the end of the process of manufacturing electrical and electrical equipment, moreover, in all In the event of a leak test failure described above, the implementation is costly

In addition, gravity casting processes using cores can create impurities on the surface of molded parts that can degrade the performance of systems that include these molded parts
