Abstract: It is proposed a two-phase heat exchanger device for a power-electronic module arrangement having a semiconductor module. The two-phase heat exchanger device includes a base plate configured for being in contact with a first semiconductor module at a first side of the base plate; and at least one tube element for a first cooling medium including a first portion having at least one evaporator channel and a second portion having at least one condenser channel. The base plate has a groove containing the tube element, wherein the groove is dimensioned for enabling thermal contact between the base plate and the first portion of the tube element and dimensioned to form a gap between the base plate and the second portion of the tube element for thermal separation of the base plate and the second portion of the tube element.

Abstract: An arrangement for cooling components of a subsea electric system including a tank filled with a dielectric fluid. The tank includes first and second sections. The arrangement includes one first electric component within the first section, and one second electric component within the second section. The arrangement includes a first heat exchanger located outside the tank and in fluid contact with the tank, and arranged during operation to be in thermal contact with sea water. The arrangement includes a pump arranged to force a flow of dielectric fluid through the first heat exchanger. Flow of dielectric fluid in the tank is by both natural and forced convection generated by the pump. The first electric component generates more heat than the second electric component. Within the first section the share of the flow by natural convection is greater than within the second section.
