This study was carried out to investigate the effect of energy transport using capillary pumped loop with PVA sponge wick. The results obtained from this study are as follows. The configuration of capillary pumped loop was adequate and PVA sponge was of great use for the manufacture of capillary pump. The energy transport reached maximum when the working fluid amount was 750cc the wall temperature distribution indicated high values through out the entire length of the pipe. As the opening of a nozzle was increased, energy transport was increased but the effect was decreased.
