There is disclosed a portable refrigerator which is formed by casting an insulating wall of foamed-in-place insulating foam in a manner which provides inner and outer shell portions on the insulating wall and a depression therein which exposes a surface of the internal thermal sink and, except for a pigtail and positive and negative contact points which points project through the outer shell portion in position to be connected with the positive and negative poles, respectively, of the thermoelectric element, completely imbeds the electrical connections. ...
In a process for making a thermoelectric device powered by a thermoelectric element of the Peltier type which is held in heat-exchange between an internal thermal sink imbedded in an insulating wall and has an external thermal sink spaced from said insulating wall, and in which electrical connections connect the positive and negative poles of said thermoelectric device with an external power source, the improvement which comprises: casting said insulating wall of foamed-in-place insulating foam about said inner thermal sink in a manner which provides an ...
