According to an embodiment of the present invention, a cooling cycle of a refrigerator in relation to a cooling cycle of a refrigerator comprises: a first cooling cycle with a first coolant pipe wherein a first coolant flows and a second cooling cycle with a second coolant pipe wherein a second coolant flows; first and second compressors compressing first and second coolants to obtain high-temperature and high-pressure gaseous coolants; an integrated condenser condensing the first and second coolants penetrated through the first and second compressors to obtain high-temperature and high-pressure fluidic coolants; first and second expansion valves changing the first and second coolants penetrated through the integrated coolant into low-temperature and low-pressure two-phase coolants; and first and second evaporators changing the coolants penetrated through the first and second expansion valves into low-temperature and low-pressure gaseous coolants. The integrated condenser comprising a plurality of first and second condensing pipes partly forming the first and second coolant pipes connecting the first and second expansion valves, and the first and second compressors and heat exchange pins in contact with the surface of the first and second condensing pipes is characterized such that the first and second condensing pipes are arranged alternately arranged in rows in a width direction. |
