Abstract
A cooling apparatus for cooling an electronic component includes a heat sink, a heat sink cover to close a top area opening of the heat sink, a tube-shaped cooling element arranged inside the heat sink for some cooling ribs of the heat sink in mechanical contact with an outer side of the tube-shaped cooling element, and an impeller with blades for generating a cooling flow of a cooling medium. The tube-shaped cooling element forms a first cooling duct to conduct the cooling flow in a first cooling flow direction. A second cooling duct opposite the first cooling duct is formed between an inner area of the heat sink and the outer side of the tube-shaped cooling element to conduct the cooling flow in a second cooling flow direction. The cooling flow is redirected from the first cooling duct to the second cooling duct or vice versa.
