Abstract
A thermoelectric cooler for cooling a sample of hot, continuously flowing gas involves a mechanical heat flow path passing from the flowing gas through a heat-exchanging tube channeling the gas, a heat-conductive block housing the tube, a thermoelectric element having a cold side abutting the block, a heat sink abutting a hot side of the thermoelectric element, and cooling air streams passing through slots in the heat sink. The heat sink is a unibody, jointless metallic body having relatively thin fins defining the slots. A high pressure blower drives turbulent air streams through the slots of the heat sink, and a thermal switch is disposed on the heat sink near the hot side of the thermoelectric element.
