Abstract
An evaporator is disclosed for a cooling circuit. The evaporator includes a housing having at least one wall for contacting a heat emitting device. A channel, the cross section of which is small enough to allow convection boiling, and a separation volume are located in the evaporator. The separation volume is located at a vapor exiting port of the channel. The evaporator can include a liquid reservoir.
Claims17
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.
Power module comprising:
- at least one heat emitting device that is thermally connected to at least one cooling circuit, the 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 the at least one wall from outside of 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;
- and
- 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.
