    Abstract: It is proposed a cooling unit (100) for a power electronic module arrangement. The cooling unit includes a two-phase heat exchanger (101) including a plurality of tube elements (120), each of which having at least one tube extending in a width direction (301) of the cooling unit, within and communicating between an evaporator portion (121) and a condenser portion (122) of the cooling unit (100). The tube elements are arranged in a spaced-apart manner along a depth direction (303) of the cooling unit forming cooling paths (213) for allowing an external cooling medium (130) to flow through the cooling paths, the cooling paths traversing the condenser portion in a length direction (302) of the cooling unit (100). The cooling unit further includes flow guides (141; 142) for forcing an external cooling medium (130) arriving at the heat exchanger through the cooling paths and then away from the cooling unit.
