Abstract:
1. An assembly for a thermoelectric heat pump comprising: a heat transfer region comprising a plurality of rows, each of the plurality of rows comprising a plurality of thermoelectric modules, each of the thermoelectric modules comprising a high temperature junction and a low temperature junction; a waste fluid channel configured to be in substantial thermal communication with a high temperature portion of the heat transfer region; a main fluid channel configured to be in substantial thermal communication with a low temperature portion of the heat transfer region; and a channel enclosure providing a barrier between fluid in the waste fluid channel and fluid in the main fluid channel; wherein the channel enclosure comprises wedge shaped projections configured to contact the heat transfer region at boundaries between the high temperature portion of the heat transfer region and the low temperature portion of the heat transfer region such that leakage between the waste fluid channel and the main fluid channel at a junction between the channel enclosure and the heat transfer region is eliminated; wherein a first row of thermoelectric modules are electrically connected in parallel, wherein a second row of thermoelectric modules are electrically connected in parallel, and wherein the first row and the second row are electrically connected in series; and wherein the plurality of thermoelectric modules are oriented such that a high temperature junction of a first thermoelectric module and a high temperature junction of a second thermoelectric module face towards one another.
