Heat exchanger for cooling electronic component, has two stages arranged consecutively, where each stage has heat exchanging channel and guiding channels that are in flow connection with heat exchanging channels of next stages

摘要

The heat exchanger has heat exchanging channels (11, 21, 31) with an inlet (9) and an outlet (33) for a medium flowing through the channels. Two stages (10, 20) are arranged consecutively in a direction of flow of the medium, where each stage has one of the heat exchanging channels. The stage (10) has parallel guiding channels (12, 22) arranged in the channel (11). The channels (11, 21) have outlets (13, 23) at the end of the respective stages. The guiding channels of the respective stages (10, 20) are in flow connection with the heat exchanging channels (21, 31) of stages (20, 30).
