ABSTRACT:
There is disclosed a thermoelectric device suitable for drying gases in which a finned heat-dissipating device is in contact with the hot face of a thermoelectric element and a thermal sink is in contact with the cold face thereof. The thermal sink has formed therein a conduit which zig-zags from an inlet at the upper part thereof to a point at the bottom thereof and then upwardly to an outlet at the other side. The conduit is formed by routing out a channel in a block and sealing it off with a face plate to provide the desired conduit. The various elements are held together by face plates spanning the heat-radiating device and the thermal sink, and the space between the two is desirably filled with insulating material. The device is used in combination with a gas analyzer in which exhaust gases, for example, from an internal combustion engine, are fed through the dryer and then into the analyzer.
