ABSTRACT

The experimental analysis presented here is based on the heat transfer performance of parallel miniature heat pipe (mHP) system intended for desktop computer processor cooling. The system consists of six single copper tube mHPs slotted into two copper blocks at the evaporator section and fifteen parallel copper sheets at the condenser section. Stainless steel wicks are inserted inside the copper tubes, while methanol and iso-propanol serves solely as working fluids. Heat transfer characteristics of mHPs are determined by conducting the experiment at various levels of heat inputs and analyzed to evaluate the performance. The overall heat transfer coefficient of the system is determined as a performance parameter. The results show that, the behavior of the heat pipe varies significantly for different heat inputs and different working fluids.

Keywords: Parallel Miniature Heat Pipes, Heat Flux, Overall Heat Transfer Coefficient, Working Fluids.
