PURPOSE: An evaporation pipe structure and a method for circulating a refrigerant of the drawer type storage are provided to efficiently cool storage by maintaining an evaporation pipe without temperature variation by intensively arranging evaporation pipes at 2/3 or 3/4 height of right and left surfaces. CONSTITUTION: An evaporation pipe structure of the drawer type storage comprises first, second, third, fourth evaporation pipes(50,52,70,90), and first, second, and third connection pipes(60,80). The first evaporation pipe is installed in one side of the storage and comprises a refrigerant inlet. The second evaporation pipe is installed in another side of the storage. The third evaporation pipe is installed in other side of the storage. The forth evaporation pipe is installed in the upper side of the storage and comprises a refrigerant outlet. The first connection pipe is installed in the rear of the storage by connecting the first and second evaporation pipes. The second connection pipe is installed in the rear of the storage by connecting the second and third evaporation pipes. The third connection pipe connects the third and forth evaporation pipes.
