Abstract
This refrigerator comprises: a body comprising a storage chamber; a thermoelectric element provided on an upper wall of the body and comprising a heat-emitting part and a heat-absorbing part; a heat dissipation sink in contact with the heat-emitting part on an upper side of the thermoelectric element; and a heat dissipation duct coupled to the upper wall. The heat dissipation duct comprises: an air inlet; and a partition part which has a height lower than the height of the heat dissipation sink, and partitions the inside of the heat dissipation duct into an inlet space and a fan accommodation space provided below the inlet space. The refrigerator further comprises a heat dissipation fan provided in the fan accommodation space. The heat dissipation duct and the heat dissipation fan are provided such that the heat dissipation fan is operable to cause air to be introduced through the air inlet, flow into the inlet space, flow into the fan accommodation space, and then flow into the heat dissipation sink.
