Liquid feeding method for thermoelectric cooling systems

摘要

A liquid suction port 34 between a heat-radiating heat exchanger 10 and a heat exchanging portion 26a of a manifold is connected to a liquid tank 51, and a self-priming pump 52 is connected to a suction port or discharge port of a circulating pump 14a in series. Then, the self-priming pump 52 is operated to pump a liquid from the liquid tank 51. After the liquid has reached a discharge port of the self-priming pump 52, the operation of the self-priming pump 52 is stopped and the liquid suction port 34 is closed. Finally, the self-priming pump 52 is removed and a coupling port between the self-priming pump 52 and the circulating passage is closed.
