Patent ID: 8763408

Claim:
An active cooling system for transferring heat from a heat source to an external heat sink comprising an ejector cooling system having a high temperature evaporator and a low temperature evaporator, and a thermoelectric cooling device having a hot side in thermal communication with the high temperature evaporator for supplying heat used to vaporize a primary fluid and a cold side in thermal communication with the low temperature evaporator for removing heat from the low temperature evaporator, wherein the elector comprises a nozzle and a mixing chamber, the mixing chamber being in fluid communication with the low temperature evaporator, the nozzle being in fluid communication with the high temperature evaporator and the mixing chamber; the ejector being disposed with respect to the high temperature evaporator and the mixing chamber to eject primary fluid from the high temperature evaporator and to use the nozzle to aspirate a secondary fluid vapor into the mixing chamber.
