- Wick must provide in order that heat pipe can be operate in any orientation. Wick provide the driving forces to circulate working fluids. A novel sintered molecular sieve and hybrid molecular sieve-Cu would be use as wick heat pipe. This paper presents the results of investigation on porosity and microstructure of molecular sieve. Physical properties of the molecular sieve such as porosity and microstructure will measured and evaluated. Porosity and microstructure of molecular sieve would affect capillary force of the wick, hence affect the performance of heat pipe. Several properties that influence the performance of wick heat pipe are capillary force, permeability, wettability and thermal conductivity. The preparation step was achieved by made wick sample. Two kind of particle size i.e. 100 µm and 200 µm and made into slurry. The slurry was shaped in the form of copper pipe in 1 inch and 60 mm diameter and length respectively. Wick sample compacted by sintering process. Sintering temperature was 950 degree for 60 second. The porosity and microstructure of wick sample tested by SEM and the results were analyzed by Image-J software to get particle shape, pore size, and porosity. The porosity will comparing with the result of capillary pumping tested. Furthermore, capillary pumping performance, porosity and microstructure of molecular sieve and hybrid molecular sieve-Cu examined by comparing with biomaterial wick. The result show that molecular sieve can be considered as a wick material.
