PURPOSE: A refrigerator compressor is provided with a small defrosted water tray, and to smoothly facilitate a heat exchange by an increased surface. CONSTITUTION: A refrigerator compressor(10) is cooled by defrosted water supplied from an evaporator. An uneven part(20) is formed on the surface of the compressor. The uneven part is extended at 0-90 degrees along the surface of the compressor, and the defrosted water flows along the uneven part. The uneven part is extended with a spiral shape along the surface. The uneven part comprises a plurality of closed curve lines, and openings are formed at the lowest parts of each closed curve line. The lowest part of an upper closed line is vertically placed to the highest part of a lower closed line. The end part of the uneven part is extended upwardly. |
