Abstract
An experiment on a generator utilizing boiling and condensation was carried out in a wind-tunnel test bench. Fuluorinert (FC5312) was used as the working fluid. A vertical tube type boiler was chosen and the hot side electrode of the thermoelectric module was processed into a low-finned surface to increase the hot side temperature. Experimental parameters were the temperature of the cooling water, the velocity and the temperature of the air. Two types of boiler and two sorts of thermoelectric material were tested and compared. As a conclusion, the thermoelement characteristic is very important for system designing, and the structure designing will improve the following characteristic of the boiler to load fluctuation.
