Hysteresis phenomena in flat-type loop heat pipe
نویسندگان
چکیده
Testing of loop heat pipes showed that the heat-load dependence operating temperature was not always unambiguous. It may have hysteresis phenomena. The had a certain relationship with previous history power variation, and also related to initial parameters pipes. has been found gas-liquid distribution in compensation chamber which depended on interaction between leak evaporator reflux liquid from condenser. rose gas phase increased.

A Titanium Based Flat Heat Pipe
1. ABSTRACT We are developing innovative heat pipes based on Nano-Structured Titania (NST) with a potential for high heat carrying capacity and high thermal conductivity. These heat pipes have a flat geometry as opposed to a cylindrical geometry found in conventional heat pipes. The flatness will enable a good contact with microprocessor chips and thus reduce the thermal contact resistance. We ...
