Abstract:
A flexible pad capable of selectably heating or cooling an animal or human body part. The pad is formed of two planar surfaces having at least two side portions disposed between said planar surfaces that are made of a mesh material for air circulation within the pad. One planar surface is made of thermal conductive material having a plurality of thermoelectric modules bonded to the conductive material. The thermoelectric modules transfer heat to or away from the conductive material. A heat sink is attached to the opposing side of each modules for dissipating heat from the conductive material during the cooling process. A rheostat has a reversing switch for changing polarity of the rheostat to either transfer heat to the thermoelectric modules and to the planar surface, or from the thermoelectric module to the heat sink.
