Two-phase heat-exchange method and device with bearing-mounted gear pump

摘要

The method involves using a corrosive coolant i.e. ammonia, partially at a liquid state and a vapor state, where viscosity of the coolant is less than water. The coolant is driven in a circuit i.e. conduits, by displacement using pumping, where the circuit comprises heat exchange units including evaporator exchanger and condenser exchanger groups with a cold source and a hot source external to the electronic circuits. A state of contact of the heat exchange units is changed by the coolant. An independent claim is also included for a diphasic type heat exchange device comprising a gear pump.
