    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.

    Abstract: A subsea power module including: a tank having a tank wall provided with an outwardly protruding corrugation, a power device arranged in the tank, a dielectric liquid which fills the tank, for cooling the power device, a pump configured to circulate the dielectric liquid in the tank, wherein the pump has a pump inlet and a pump outlet, a duct arranged in the corrugation such that a chamber is formed between a tip of the corrugation and the duct, wherein the duct has a duct inlet connected to the pump outlet, and wherein the duct is provided with at least one duct outlet opening into the chamber, and a distancing structure configured to space apart an outer surface of the duct facing the tank wall and the tank wall in the corrugation, whereby gaps are formed between the duct and the tank wall in the corrugation, enabling dielectric liquid that has been discharged through the at least one duct outlet into the chamber to be squeezed out from the chamber and the corrugation, and flow towards the pump inlet.

    IPC: H01F27/10

    Abstract: A static electric induction system is disclosed. The system includes a heat generating component, cooling fluid, a cooling duct along the heat generating component and a pumping system configured for driving the cooling fluid through the cooling duct, wherein the pumping system is configured for applying a varying flow rate over time of the cooling fluid in the cooling duct along a predetermined flow rate curve which is a function of time.
