Thermal management device for an electrical and / or electronic component of a motor vehicle.

Abstract

Thermal management system for an electrical and / or electronic component of a motor vehicle. Thermal management system for an electrical and / or electronic component of a motor vehicle comprising: - a hollow wall (31) of which a first face (311) is intended to be disposed near or in contact with at least one component of an electrical or electronic element (2) to be cooled or heated, - a substantially cylindrical channel (32) extending inside the hollow wall (31) in a direction of flow of the heat transfer fluid, the channel (32) being in contact with a given portion of the first face (311), - a turbulator (33) extending in the channel (32) in the direction of flow of the heat transfer fluid, and - a means for circulating the heat transfer fluid in the channel (32), the device being characterized in that a shape of the turbulator (33) varies according to the direction of flow of the heat transfer fluid.

Claims

a calculation of a propeller pitch which allows the implementation of the heat transfer power (Pj).

4. Thermal management system (3) according to any one of the preceding claims, characterized in that the turbulator (33) is in the form of a propeller whose pitch varies according to the direction (Dl) of flow of the heat transfer fluid.

5. Thermal management system (3) according to the preceding claim, characterized in that the turbulator (33) is made by twisting a sheet of material so as to make a twist, and / or in that the material used to make the turbulator (33) is a metal, for example aluminium, or a plastic material, or a composite material.

6. Thermal management system (3) according to claim 4 or 5, characterized in that the edges of the helix formed by the turbulator (33) are fixed to an internal wall (321) of the channel (32), in particular by spot welding and / or resistance welding and / or shrink fitting.

7. Motor vehicle (100) comprising a thermal management system (3) according to any one of the preceding claims.
