A miniature Loop heat Pipe(LHP) has a great potential in cooling high power computer chips over a long distance. The present study was focused on modelling divers operational characteristics as a capillary limitation, heat transfer paths at the evaporator and those results were used to analyse the performance test data. The experimental model of LHP was designed to have a maximum capacity of heat transport of about 50W when operated under room air cooling condition. The evaporator was of a flat cylindrical shape(30D×14.5H㎜). Ethanol was used as a working fluid. Temperatures at the liquid and vapor lines, evaporator and condenser walls were measured.
