COOLING APPARATUS

摘要

This invention relates to a cooling apparatus comprising a first cooling element (5) with first channels (6) extending between a first manifold (1) and a second manifold (2) and with a base plate (9) with a first surface (10) for receiving a heat load from an electric component (11), and a second cooling element (14) with second channels (16) extending between a third manifold (3) and a fourth manifold (4). A first section (21) of the second cooling element (14) is provided with openings (19) for allowing an airflow (18) to pass through the first section (21). The second cooling element (14) comprises a second section (22) provided with openings (19), and the cooling apparatus is configured to conduct the airflow (18) which has passed through the first section (21) through the openings (19) of the second section (22).
