Patent ID: 7841385

Claim:
A cooled electronics system comprising: a multi-fluid cooled electronics module, the multi-fluid cooled electronics module being cooled by a first fluid coolant received at a first inlet thereof and a second fluid coolant received at a second inlet thereof, wherein the first fluid coolant and the second fluid coolant are immiscible and have different densities; at least one heat exchanger for cooling fluid effluent from the multi-fluid cooled electronics module, the fluid effluent comprising the first fluid coolant and the second fluid coolant; a pump for providing the first fluid coolant and the second fluid coolant to the multi-fluid cooled electronics module from the heat exchanger, the pump comprising: a first fluid path for pumping the first fluid coolant and a second fluid path for pumping the second fluid coolant, the first fluid path comprising a first pumping chamber and the second fluid path comprising a second pumping chamber; at least one diaphragm separating the first pumping chamber and the second pumping chamber; and an actuator coupled to the at least one diaphragm for transitioning the at least one diaphragm between a first position and a second position, wherein transitioning of the at least one diaphragm to the first position pumps first fluid coolant from the first pumping chamber while concurrently drawing second fluid coolant into the second pumping chamber, and transitioning of the at least one diaphragm to the second position pumps second fluid coolant from the second pumping chamber while concurrently drawing first fluid coolant into the first pumping chamber.
