How do thermoelectric materials work
WebThermoelectric materials could make very useful devices: by passing an electrical current through them, they could provide cooling with no moving parts; by delivering heat to them (possibly waste heat from an engine or industrial process) they could generate electricity. However, there is a difficulty, because for large heat transport, large electrical currents … WebAs direct current passes through the thermoelectric device, it actively pumps heat from the cold side sink to the one on the hot side. The fan on the hot side then circulates ambient air between the sink’s fins to absorb some of the collected heat.
