Abstract
The present invention uses electric current to either chill or warm air ambient air. The Portable Thermoelectric Cooling and Heating Device is composed of an array of thermoelectric units, a driving fan, a cold sink, a hot sink, air baffles and a cooling fan. The thermoelectric units are arranged in contact with the cold sink (cold side) and hot sink (hot side). Applying a current causes a temperature difference to develop between each side. The driving fan creates a pressure gradient is to pull air through the center of the cold sink. The cooling fan pulls air through an arrangement of baffles connected to the hot sink to help dissipate heat. The result is chilled or hot air, depending on the direction of the current. The invention allows for several improvements over current heating and air-conditioning systems: a simplified design without moving parts, elimination of the need for FREON, improved versatility and others.
