HEAT EXCHANGER

摘要

The invention relates to a heat exchanger (1) comprising a base plate (2) for receiving a heat load from one or more electric components (3), an evaporator (5) being in thermal contact with a surface of the base plate (2) for transferring said heat load into a first fluid in the evaporator channels (7), and a condenser (8) dissipating heat from the first fluid. In order to provide an efficient heat exchanger the heat exchanger comprises a collector space (16) receiving first fluid from the condenser (8'), and the collector space (16) which is located higher than the lower ends of the evaporator channels (7) is in fluid communication with lower ends of the evaporator channels (7) for passing first fluid received from the condenser (8) to the lower ends of the evaporator channels (7).
