Thermoelectric cooling with plural dynamic switching to isolate heat transport mechanisms

摘要

A thermoelectric element (1) is coupled to a hot sink (6) and a cold sink (4) through respective switches (7,8) which are closed to establish thermal coupling of hot sink and cold sink with the thermoelectric element. A controller (9) selectively actuates the switches which has microelectro mechanical device, so as to establish a potential difference across the thermoelectric element. The duty cycle of the voltage occurs the thermoelectric element correlates with that of the two switches. The duty cycle of the switch (7) for selective switching is lesser than that of the switch (8). An INDEPENDENT CLAIM is included for operating method of thermoelectric cooling apparatus.
