Abstract
A subsea unit includes a housing containing a dielectric liquid, a first heat generating component and a second heat generating component. The first heat generating component is arranged in thermal connection with the housing and the second heat generating component is arranged at a distance from the housing. A method of cooling heat generating components contained in a housing of a subsea unit is also presented.

17. A subsea unit comprising:
-
a housing containing a dielectric liquid; a first heat generating component; and a second heat generating component, wherein the first heat generating component is arranged in thermal conductive connection with the housing, wherein the second heat generating component is arranged at a distance from the housing, wherein the first heat generating component is arranged in thermal conductive connection with a side wall of the housing. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 32, 33, 34, 37)

31. A method of cooling heat generating components contained in a housing of a subsea unit comprising the steps of:
-
providing a housing; arranging a first heat generating component in thermal conductive connection with a side wall of the housing; arranging a second heat generating component at a distance from the housing; filling the housing with a dielectric liquid so that the heat generating components are immersed in the dielectric liquid; arranging the subsea unit under the sea water surface, preferably on the seabed, so that the housing is cooled by the sea water; and supplying electric power to the heat generating components so that the first heat generating component heats up the dielectric liquid and thus a convective flow of the dielectric liquid is created within the housing, cooling also the second heat generating component.
