Fluid flow and heat transfer in a dual-wet micro heat pipe [PDF]

, 2007
Micro heat pipes have been used to cool micro electronic devices, but their heat transfer coefficients are low compared with those of conventional heat pipes. In this work, a dual-wet pipe is proposed as a model to study heat transfer in micro heat pipes.
