Abstract:
A cooling sheet for pillow includes a plurality of thermoelectric coolers, a thermal pad, and a heat sink. The thermoelectric coolers are electrically connected one another in series, with a first junction and a second junction. The thermal pad is thermally connected to the first junction of the thermoelectric coolers. The heat sink is thermally connected to the second junction of the thermoelectric coolers. The thermal pad is adapted to be used with a pillow, and the temperature of the thermal pad is controlled by the thermoelectric coolers. The thermoelectric coolers include first and second metals that are dissimilar from the first metal. The first and second metals are connected to each other at two junctions forming Peltier junctions. The thermoelectric coolers further include an EMF source for providing electric current through the Peltier junctions. The thermoelectric coolers can be realized by two dissimilar semiconductors.
