Abstract
A cooling device for cooling a power module has cooling channels between a base and a cover of the cooling device. A cooling medium can flow in the cooling channels. The base and/or the cover is in the form of a metal surface for thermal connection to the power module. Side walls of the cooling channels are formed by ribs. At predefined positions, the ribs have local deflections from the usual course of the cooling channel in question so that a turbulent flow of the cooling medium occurs locally at each deflection.
Claims19
A cooling device for cooling a power module, comprising:
- a base:
- a cover:
- cooling channels between the base and the cover of the cooling device,
- wherein the cooling channels are arranged such that a cooling medium can flow in the cooling channels,
- wherein the base and/or the cover are/is a metallic surface for thermal connection to the power module,
- wherein side walls of the cooling channels are formed by ribs and define a usual course of each of the cooling channels,
- wherein the cooling channels and ribs extend in a first direction:
- wherein the ribs have, at predefined positions, local deflections, wherein the local deflections deflect from the usual course of the cooling channel in question, such that turbulent flow of the cooling medium occurs locally at the respective local deflection.
