Abstract

The invention relates to an air heat exchanger (1) for cooling power electronic components (2), comprising:-a carrier plate (3) having a receiving region (4) for receiving the power electronic components (2); -a heat exchange plate (7) which is coupled to the carrier plate (3), at least one hermetically closed cavity (10) for accommodating a working medium (13) being defined by the carrier plate (3) and the heat exchange plate (7), the cavity (10) having an evaporator (11) and a condenser (12), the evaporator (11) being arranged at a distance from the condenser (12) in the heat transfer direction (14); and a cooling rib (15) coupled to the heat exchange plate (7).

Description

technical field [0001] The invention relates to an air heat exchanger for cooling power electronic components. Background technique [0002] An embodiment of an air heat exchanger is known from EP 0051315 A2. Although the aim of EP0051315A2 was already to improve the heat dissipation of the individual components, this has not yet been adequately addressed in EP0051315A2 for components with high thermal output, such as for example power electronics components. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and to provide an air heat exchanger which also has improved heat dissipation for electronic components with high thermal output. [0004] One possibility to improve heat dissipation consists in the application of liquid heat exchangers. However, liquid heat exchangers have the disadvantage of high energy consumption for cooling medium circulation. Furthermore, liquid heat exchangers have a compl...
