<p>The present invention relates to a refrigerator having a direct cooling storage room, which increases a refrigerant flow and a contact area by processing a spiral groove on the inner surface of an evaporator for a direct cooling refrigerator, thereby improving heat exchange performance. The refrigerator cools the direct cooling storage room through an evaporator by condensing the refrigerants, compressed in a compressor, in a condenser. The evaporator includes: a tube for surrounding the outer wall of the storage room; and a groove formed on the inner surface of the tube.</p> |
