Abstract
A refrigerator as disclosed herein may include a refrigerator body having a freezing compartment and a refrigeration compartment, a cooling circuit including a compressor, a condenser, and an evaporator to cool the freezing compartment and the refrigeration compartment using a first refrigerant, and a thermosyphon that includes a pipe for a second refrigerant to flow. The pipe may have a first section having a first prescribed shape for condensing refrigerant and a second section having a second prescribed shape for vaporizing refrigerant. A valve may be provided at the pipe to operate the thermosyphon. The cooling circuit and the thermosyphon may be operated independently. The thermosyphon may provide auxiliary cooling for the refrigeration chamber when the cooling circuit is not operational.
