Patent ID: 7059137

Claim:
A portable heating/cooling system, comprised of: (a) a multi-sided heat exchanger made of metal with high heat conductivity; (b) said heat exchanger having holes running lengthwise through its center; (c) a stacked arrangement of thermoelectric modules attached to periphery of said heat exchanger; (d) an inlet duct for allowing ambient air to enter said passageways; (e) a driving fan for forcing ambient air through said heat exchanger; (f) a vent in which chilled or heated air is directed away from the system; (g) a heat dissipating unit for cooling the hot sides of the thermoelectric units; (h) a master control unit for determining the polarity of current through said thermoelectric modules; (i) a master control unit for adjusting the temperature of expelled air from said heating/cooling system; (j) an of arrangement of thin-shaped metal heat sink wafers or baffles attached to periphery of heat sink, constructed to maximize surface area; (k) a cooling fan for forcing ambient air through arrangement of said wafers or baffles; (l) an inlet duct to allow ambient air to enter said heat dissipating unit; and (m) a vent to expel heated air from said heat dissipating unit.
