Refrigerator

摘要

A refrigerator includes a main body in which a first storage compartment is defined, and a heat exchange chamber defined in the main body. An evaporator received in the heat exchange chamber. A second storage compartment is provided in the first storage compartment and a quick cooling module to cool an inside of the second storage compartment is provided, where the quick cooling module heat-exchanges with a refrigerant pipe of the evaporator. The quick cooling module includes a thermal conductive unit in thermal conduction with the refrigerant pipe, and a thermoelectric device having a first surface in thermal conduction with the thermal conductive unit to heat-exchange with the thermal conductive unit when current is supplied and a second surface facing the second storage compartment.

1. A refrigerator, comprising:
a main body in which a first storage compartment is defined; a door opening or closing the first storage compartment; a heat exchange chamber defined in the main body; an evaporator disposed in the heat exchange chamber and including a refrigerant pipe; a second storage compartment defined in the first storage compartment, the second storage compartment configured to be maintained at a temperature lower than the temperature of the first storage compartment and located on a front side of the heat exchange chamber; a drawer assembly received in the second storage compartment; a partition wall disposed between the second storage chamber and the heat exchange chamber, the partition wall including: a cool air inflow hole allowing flow of air between the heat exchange chamber and the drawer assembly; and a cool air discharge hole allowing flow of air between the drawer assembly and the heat exchange chamber; a guide part disposed between the drawer assembly and the partition wall and having a cool air guide passage which allows flow of air between the cool air inflow hole of the partition and the drawer assembly; a quick cooling module configured to rapidly cool the second storage compartment, the quick cooling module including: a thermal conductive unit contacting the evaporator by surrounding at least a portion of the refrigerant pipe of the evaporator, in order to transfer heat to the evaporator; a thermoelectric device including: a heat emission surface contacting the thermal conductive unit, in order to transfer heat to the thermal conductive unit when current is supplied; and a heat absorption surface which is opposite of the heat emission surface; and a heat dissipation member contacting the heat absorption surface of the thermoelectric device, and disposed inside the cool air guide passage, wherein air primarily cooled by the evaporator in the heat exchange chamber flows into the cool air guide passage through the cool air inflow hole of the partition wall, the air flowing along the cool air guide passage is further cooled by the heat dissipation member and enters the drawer assembly, and the air in the drawer assembly is configured to return to the heat exchange chamber through the cool air discharge hole of the partition wall.
