Two-phase heat transfer without de-gassing

摘要

An apparatus suitable for two-phase heat transfer where volatile fluids such as volatile halogenated organic compounds may be used as a heat-transfer fluid without first de-gassing the volatile fluid or having to maintain the apparatus/system in a de-gassed state. Preferably, the apparatus is self-modulating. It comprises a heat source (30), an evaporator (32), a condenser (36), a heat sink (37) and an expansion device (38) to maintain a constant operating pressure and constant temperature of the heat source (30).
