Refrigerator

A refrigerator comprising:

• a main body including an upper wall;
• a storage compartment formed inside the main body;
• a first door and a second door configured to open and close the storage compartment;
• a rotation bar coupled to one of the first door and the second door and being rotatable so as to cover a gap between the first door and the second door when the first door and second door are closed;
• a thermoelectric element on the upper wall and including:
• a heating portion which generates heat, and
• a cooling portion which absorbs heat and is configured to cool the storage compartment;
• a heat dissipation sink in contact with the heating portion so that the heat dissipation sink is heated by the heat generated by the heating portion;
• a heat dissipation fan configured to generate a flow of air toward the heat dissipation sink so that the flow of air exchanges heat with the heat dissipation sink;
• and
• a heat dissipation duct including:
• a first discharge duct portion configured to guide a first portion of the flow of air, which exchanged heat with the heat dissipation sink, to be discharged to an outside of the main body;
• and
• a second discharge duct portion configured to guide a second portion of the flow of air, which exchanged heat with the heat dissipation sink, to be discharged to the rotation bar to prevent dew from condensing on the rotation bar.
