Abstract: A refrigerator may include a sensor configured to measure temperature, a thermoelectric device module having at least one fan and configured to cool the storage compartment; and a controller that controls a rotation speed of the fan. The rotation speed of the fan may be determined based on at least one of whether a storage compartment temperature condition measured by the sensor exists or whether an initial power input condition exists. The thermoelectric device module may be controlled differently in a first temperature region, in a second temperature region, and in a third temperature region of the storage compartment. When an initial power condition exist such that power is initially supplied to the refrigerator, the fan is controlled to spin at a rotation speed that exceeds a rotation speed corresponding to the third temperature region until a preset temperature within the second temperature region is reached.

Abstract: A thermoelectric module that has a thermoelectric element, an axial flow fan, and a heat sink and that is installed at a rear wall of the storage chamber to cool the storage chamber. The heat sink has a base configured to come in surface contact with the thermoelectric element, fins protruding from the base toward the axial flow fan and spaced apart from each other, and heat pipes having base passing portions passing through the base and fin passing portions passing through the fins and configured to transfer heat from the base to the fins. Each of the fins includes a first part arranged opposite to the hub and a second part disposed at one of both sides of the first part to face the vanes and protruding further from the base toward the axial flow fan than the first part.

Abstract: A refrigerator may have an ultra-low temperature cooling module for cooling an ultra-low temperature compartment that includes a thermoelectric element having a heating surface and a heat absorption surface disposed to oppose the heating surface and a heat conduction unit evaporation part whose one side is in contact with the heating surface of the thermoelectric element and the other side is connected to a refrigerant pipe of an evaporator to transmit heat emitted from the heating surface of the thermoelectric element to the refrigerant. An amount of heat exchange between a central portion of the heating surface having a relatively high temperature and a refrigerant of the heat conduction unit evaporation part may be greater than an amount of heat exchange between a peripheral portion of the heating surface surrounding the central portion and the refrigerant.
