Abstract: Disclosed herein is a refrigerator including a cooling cycle mechanism having improved cooling cycle efficiency by more effectively performing heat exchange between a refrigerant discharged from an evaporator and a refrigerant discharged from a condenser. The refrigerator includes a cooling cycle mechanism including a compressor, a condenser, and an evaporator. The refrigerator also includes a first pipe configured including a first heat exchanger and configured to guide the refrigerant from the condenser, to the evaporator. The refrigerator further includes a second pipe including a heat exchanger and configured to guide the refrigerant from the evaporator, to the compressor. The second heat exchanger is adjacent to first heat exchanger and configured to exchange heat with the first heat exchanger. The first heat exchanger and the second heat exchanger are arranged to guide the refrigerant in a same direction.

Abstract: A refrigerator includes a housing body including an inner space of the refrigerator and a cooling cycle mechanism configured to cool the inner space. The housing body includes a plurality of housing body elements separated along a predetermined separate surface, and the plurality of housing body elements is removably coupled to each other to allow an end surface of one of the plurality of housing body elements to face an end surface of another one of the plurality of housing body elements. A sealing mechanism configured to form an air surface between opposite end surfaces is provided to prevent air from flowing into or from the inner space through between the opposite end surfaces.

Abstract: Disclosed is a heat exchanger that improves heat conduction performance. The heat exchanger includes at least one refrigerant tube including a plurality of sections arranged in a first direction and a plurality of heat exchanger fins arranged on the plurality of sections. Each of the plurality of heat exchanger fins includes at least one through hole provided to allow the at least one refrigerant tube to be inserted thereinto in a second direction perpendicular to the first direction and at least one contact member configured to protrude from one surface of the heat exchanger fin around the through hole and surround an outer circumferential surface of the refrigerant tube.
