Abstract:
A thermoelectric cooling device comprises a liquid heat exchanger, at least two air heat exchangers, and at least two thermoelectric modules. The liquid heat exchanger includes a liquid circulation path through which liquid coolant flows to exchange heat with the liquid heat exchanger. Air flows over each of the air heat exchangers to exchange heat with the respective air heat exchanger. A first thermoelectric module is thermally coupled on a first side with a first side of the liquid heat exchanger and on a second side with a first air heat exchanger to transfer heat between the air heat exchanger and the liquid heat exchanger. A second thermoelectric module is thermally coupled on a first side with a second side of the liquid heat exchanger and on a second side with the second air heat exchanger to transfer heat between the air heat exchanger and the liquid heat exchanger.

Abstract:
A heat exchanger includes a plurality of tubes (12), each tube configured for a flow of fluid therethrough and one or more fins located between adjacent tubes of the plurality of tubes. The one or more fins are spaced by a fin pitch (Fp,18) and are configured to improve thermal energy transfer between the plurality of tubes and ambient air. Each fin includes a fin face extending between the adjacent tubes, a substantially planar fin cap (22) connected to the fin face secured to one or the tubes, and a fin radius (Rc,26) connecting the fin face to the fin cap such that the fin radius is reduced to promote condensate removal from the heat exchanger.
