Cooling and heating device for electric vehicle

Abstract

A cooling and heating device for an electric vehicle includes a blower unit, which contains therein a blower in order to forcibly blow intake air. A temperature control unit is connected to the blower unit to receive air that is blown from the blower unit. A heat exchanger core having a thermoelectric element is disposed inside the temperature control unit. A heat pipe transfers heat. One end of the heat pipe is in contact with one surface of the thermoelectric element. Heat dissipation fins are disposed on the other end of the heat pipe. A cooling passage contains therein the heat dissipation fins of the heat pipe. Coolant fluid flows inside the cooling passage so that the coolant fluid performs heat exchange with the heat dissipation fins. The cooling and heating device can be used with electric vehicles and can increase cooling efficiency.

         2 . The cooling and heating device of  claim 1 , comprising a plurality of heat pipes for transferring heat. 
     
     
         3 . The cooling and heating device of  claim 1 , wherein the heat exchanger core is disposed on one end of the heat pipe, and includes:
 a plurality of thermoelectric elements, wherein one surface of each of the thermoelectric elements is in contact with an outer surface of the heat pipe;   heat exchanger fins in contact with the other surface of each of the thermoelectric elements; and   an insulator disposed between the heat pipe and the heat dissipation fins to hold the thermoelectric elements.   
     
     
         4 . The cooling and heating device of  claim 1 , wherein the cooling passage includes:
 a circulation pump for circulating the coolant fluid; and   a water-cooling blower fan for blowing outer air to the coolant fluid that is circulated by the circulation pump.   
     
     
         5 . The cooling and heating device of  claim 4 , wherein a heat exchanger chamber is provided between the circulation pump and the water-cooling blower fan, and the heat dissipation fins are disposed in the heat exchanger chamber. 
     
     
         6 . The cooling and heating device of  claim 4 , wherein the water-cooling blower fan is disposed in a water-cooling heat exchanger, and the heat dissipation fins are disposed inside a lower header of the water-cooling heat exchanger. 
     
     
         7 . The cooling and heating device of  claim 1 , wherein the heat dissipation fins are positioned higher than the heat exchanger core. 
     
     
         8 . The cooling and heating device of  claim 1 , wherein the temperature control unit further includes a drain line, wherein the drain line discharges moisture that is produced from the heat exchanger core out of the vehicle.
