Abstract
The cooling of power modules used in high-power systems, such as three-phase inverters, may require a cooling apparatus that is heavier than desired for some applications, such as electric vehicles. A cooling apparatus is disclosed that can provide sufficient cooling in a weight-reduced package. Additionally, assembly methods are disclosed that make the cooling apparatus more robust to shocks and vibrations, which may be experienced by electric vehicles.
Claims20
A cooling apparatus for a power module, the cooling apparatus comprising:
- a body including:
- a basin having a bottom surface offset from a top surface by a depth;
- and
- a cover coupled to the top surface of the body by an adhesive, the cover including:
- a first material layer facing the basin;
- and
- a second material layer facing the power module.
