In heating and cooling assemblages, that use a thermoelectric module of the Peltier type held tightly between heating and cooling members, an improvement, for avoiding fracture of the frangible components of the Peltier type thermoelectric module, is provided by using a clamping means, that acts against the members clamped against the thermoelectric module, that employs spring means that exert the assembly pressure against the thermoelectric module\s substrates. The spring means desirably apply force in line with the central portion of the module\s substrates, where the hottest portion of the module\s substrate is located. The spring means employ one or more elongated leaf springs whose center is offset from the ends of the springs that are engaged by selectively actuatable clamping means. In one specific form a cooling box for use in the field is equipped with assemblages, as disclosed, provided at the corners of the box.

In an enclosed multi-edged box whose interior is to be selectively cooled or heated by use of thermoelectric modules of the Peltier type; the provision of at least one short cornering wall section, which joins two principal walls of the box, and a heat transfer unit mounted on the cornering wall section in heat conducting relationship therewith, the heat transfer unit including a first heat conducting member secured to the outside of the cornering wall section, a heat exchange member operatively associated with the first heat conducting member and spaced therefrom; a Peltier type thermoelectric module interposed between said first heat conducting member and the heat exchange member; a pair of elongated clamping means associated with the first heat conducting member and heat exchange member for clamping same against opposite substrates of the thermoelectric module; elongated bowed spring means operatively associated with the pair of clamping means for clamping the heat exchange member in heat conductive relation against one substrate of the module, with the center of the spring means resiliently biasing the heat exchange member against the substrate of the module that engages the heat exchange member; and fin means on the heat exchange member for exchanging heat therefrom with ambient air.
