Abstract: The present invention relates to a multi-orientational cooling system with a bubble pump for generation of a circulating flow of cooling fluid. The cooling system is a closed cooling system comprising at least one hollow member facilitating flow of the cooling fluid, comprising a first heat-receiving part, a heat-emitting part, and a tubular first part adapted for functioning, in a first angular orientation of the system, as a first bubble pump for generation of a fluid flow in the system and being positioned down-stream the first heat-receiving part, and a tubular second part adapted for functioning, in a second angular orientation of the system, as a second bubble pump for generation of a fluid flow in the system and being positioned downstream the first heat-receiving part.

Abstract: A device for cooling, in particular electronic components, in particular of a processor unit, having an evaporator for the absorption of heat in a coolant in particular by means of evaporation; a gas cooler for cooling of the coolant in particular by means of condensation; a first coolant conduit for communicating connection of an evaporator outlet with a gas cooler inlet; a second coolant conduit for communicating connection of a gas cooler outlet with an evaporator inlet; a filling device for filling of the device with coolant; and the filling device is arranged on the evaporator or on the gas cooler.
