TWO-PHASE HEAT TRANSFER APPARATUS

摘要

An evaporator is provided for a two phase heat transfer apparatus. The evaporator includes an evaporator base, an evaporator body connected to the evaporator base and a capillary wicking material inside the evaporator body in contact with an interior surface of the evaporator base. The evaporator may further include a thermal separator between the evaporator body and the evaporator base which is made of a low thermal conductivity material coated with a metallic surface layer. The thermal separator reduces heat transfer from the evaporator base to the evaporator body whilst the metal surface layer allows the evaporator base and body to be hermetically sealed. The evaporator body may also include a heat shield that reduces transfer of heat from the evaporator base to liquid refrigerant in the evaporator body. An insert for inserting inside a heat exchange tube is also provided.
