    Patent number: 4453503
    Abstract: A heat transfer device using a thermal electric solid state heat pump coupled to a source of electrical energy to transfer heat between the heat pump and a pair of heat exchangers. One of the heat exchangers defines a fluid flow path for the transfer of heat between that heat exchanger and heat pump. The other heat exchanger transfers heat between the heat pump and the ambient environment. The direction of heat transfer is determined by the polarity of electricity supplied to the heat pump.
