Patent ID: 8134833

Claim:
Cooling circuit for cooling at least one heat emitting device, said cooling circuit comprising: an evaporator having a housing with at least one wall that is thermally connectable with the at least one heat emitting device such that heat from the at least one heat emitting device is introducible to said at least one wall from outside the housing, the evaporator having at least one channel whose cross section is sized such that convection boiling is achievable in at least a portion of said at least one channel during use of the cooling circuit; at least one separation volume located at a vapor exiting port that is fluidly connected to said at least one channel and to at least one liquid reservoir; wherein the at least one channel includes at least one channel building element arranged inside the housing, said at least one channel building element comprising at least one surface at a first side of said at least one channel building element facing an inside surface of said wall and constituting the at least one channel with said wall and the at least one channel building element is an insert.
