    Abstract: A two-phase heat exchanger for cooling at least one electronic and/or electric component with an evaporator and a condenser is provided. The evaporator is adapted to transfer heat from the electronic and/or electric component to a working fluid. The condenser comprises a roll-bonded panel, which has a first channel which has a first connection port and a second connection port. The evaporator has a second channel and first connection openings and second connection openings. The first connection port of the first channel is connected to one first connection opening of the evaporator and the second connection port of the first channel is connected to one second connection opening of the evaporator and the working fluid is provided in order to convey heat by means of convection from the evaporator to the condenser by flowing from the second channel through the first connection opening or the second connection opening of the evaporator towards the first channel.
