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.
