AB - This paper describes an experiment investigation of Peltier water cooler that modified by adding a thermosiphon enhance heat dissipation from hot junction. The thermosiphon is worked by natural circulation and working three different are tested to explore its effectiveness, which water, kerosene, and ethylene glycol solution (50/50 mixture of distilled water). Experimental work is conducted using domestic Peltier water cooler with a 760 g water tank capacity. The thermosiphon unit is added as a modification the traditional finned heat sink connected to fan. Two different arrangements of thermosiphon are investigated, one with single riser tube, while the other has two riser tubes. The results indicates that the design with single riser tube show stable operation and gives efficient heat dissipation rather that the dual riser tube. The findings also revealed that kerosene is the best fluid to use in increasing the coefficient of performance in the system.
