Thermoelectric heat pumps

A thermoelectric heat pump (10) comprising one or more thermoelectric modules (11) having a hot side connected to a first heat exchanger (12) and a cold side connected to a second heat exchanger (13), characterised in that it comprises a pair of elongated bar-like elements (14, 15) made of an electrically and thermally insulating material which are arranged at two parallel sides of the heat exchangers (12, 13), at least partly interposed between facing flanges of said heat exchangers, at least one of said elongated bar-like elements (14, 15) including electric conductors for supplying power to the thermoelectric modules (11), as well as conductors for supplying control signals therefor, and that said heat exchangers (12, 13) contacting the thermoelectric modules (11) are linked one another via a plurality of fasteners (16), each fastener being formed of a substantially C-shaped metal clip and being apt to grip with both ends (16′,16″) thereof the facing flanges of the heat exchangers (12, 13) in order to hold them together, at least one (16″) of said ends of the fastener (16) gripping a corresponding flange of a heat exchanger (12, 13) indirectly with the interposition of a transverse extension (17) of the elongated bar-like elements (14, 15) so as to break the thermal bridge which otherwise would be formed between one heat exchanger and the other.
