Abstract
A refrigerator includes a hollow casing, an insulation layer securely attached to an inner side thereof, a freezer area defined in the casing and in communication with the opening of the casing, a refrigeration area defined in the casing and separated from the freezer area by a baffle. The refrigeration area is in communication with the opening. A first conductor and a second conductor are sandwiched between the baffle and the insulation layer. A thermoelectric cooling chip is selectively actuated for reducing and increasing air temperature. A first heat dissipation device is provided to dissipate heat from the thermoelectric cooling chip, such that heat conduction between the first conductor and the second conductor is able to conduct cold air from the thermoelectric cooling chip to the refrigeration area and the freezer area.
