Patent Number: 6,293,107

Title: Thermoelectric cooling system

Abstract: Air traps 37a, 37b are disposed on one side adjacent at least one of suction and discharge ports of circulating pumps 14a, 14b forming a heat radiating or heat absorbing cycle. Also, the circulating pumps 14a, 14b are disposed at a level higher than heat-radiating and cooling heat exchangers 10, 20 and first and second heat exchanging portions 26a, 26b to recover air bubbles mixed therein so that the air bubbles circulated can be reduced to improve the heat efficiency.
