摘要： 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.

摘要： A refrigerator includes: a main body having a storage chamber; a door for opening and closing the storage chamber; a thermoelectric module for cooling the storage chamber; an outside temperature sensor for detecting an outside temperature; a storage chamber temperature sensor for detecting the storage chamber temperature; and a control unit for applying a voltage within a range between the maximum voltage and the minimum voltage to the thermoelectric module. The control unit applies the set voltage, not the maximum voltage, to the thermoelectric module when the outside temperature is the uppermost outside temperature range among the plurality of outside temperature ranges and thus the temperature of the control is lowered and power consumption is reduced.

摘要： A refrigerator includes a cabinet, a thermoelectric element module, a support disposed at a lower surface of the cabinet, and a heat dissipation cover coupled to a rear side of the cabinet. The thermoelectric element module includes a thermoelectric element including a heat absorption portion and a heat dissipation portion, a first heat sink contacting the heat absorption portion, a first fan facing the first heat sink, a second heat sink contacting the heat dissipation portion, a second fan exposed to an outside of the heat dissipation cover, and an insulating member between the first heat sink and the second heat sink. The heat dissipation cover is configured to guide air from the second fan in a vertical direction, and the support defines an air passage between the lower surface and a floor to allow air to be discharged to a front side through a lower side of the cabinet.

摘要： A refrigerator includes a thermoelectric element module, and a defrosting temperature sensor, and a controller configured to control operation of the thermoelectric element module. The thermoelectric element module includes a thermoelectric element including a heat absorption portion and a heat dissipation portion, a first heat sink in contact with the heat absorption portion, a first fan facing the first heat sink, a second heat sink in contact with the heat dissipation portion, and a second fan facing the second heat sink. The controller is configured to initiate a natural defrosting operation for removing frost on the thermoelectric element module at every preset period, and terminate the natural defrosting operation based on a temperature measured by the defrosting temperature sensor corresponding to a reference temperature. The controller is configured to control operation of the thermoelectric element and rotation of the first and second fans in the natural defrosting operation.

摘要： 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.
