Loop Vapor Chambers for Consumer Applications
Keywords: Two Phase, Loop Heat Pipe, Commercial
Passive two phase loop devices, commonly known as Loop Heat Pipes or Loop Thermosiphon, have been used in high end applications for over a decade. They offer performance advantages over traditional heat pipes such as higher capacities, the ability to move heat long distances and some designs, performance against gravity. What has limited these from becoming more mainstream products has been the cost. Loop Heat Pipes for satellite applications can cost $$1000's of dollars each. An investigation was done to see if this technology can be applied to more mainstream applications such as PCs, Servers and telecom equipment. Results of this investigation will be reported. Included in this study are both performance characteristics as well as cost drivers for this type of product. Two examples will be looked at in detail, a design for small form factor PCs and a design for a 1U type box.
