Heat pipes, heat transfer methods using heat pipes and heat transfer fluids used in heat pipes

摘要

The present invention also includes a method of transferring heat, the method comprising: (a) comprising a liquid working fluid comprising at least about 60 wt% of cis 1-chloro-3,3,3-trifluoropropene. Providing a heat pipe comprising an evaporation section and a condensation section comprising a working fluid vapor comprising cis 1-chloro-3,3,3-trifluoropropene; (b) placing the evaporation section in thermal communication with a body, fluid, surface, etc. to be cooled; And (c) placing the condensation section in thermal communication with a body, fluid, surface, and the like to be heated.
