A method for manufacturing a cold water tank assembly within which purified water at room temperature passes through a plurality of heat exchange chambers having a spiral orbit, the method comprising:
- preparing a cold water tank, including:
- preparing a cylindrical body having an opened inlet and an accommodation space therein, and preparing a cap configured to seal the opened inlet of the body;
- preparing an evaporator, including:
- preparing the evaporator having a spiral shaft tube having a prescribed length and a spiral tube configured to form a plurality of turns of first spirals along the length with a predetermined first pitch around the spiral shaft tube by bending a side of the spiral shaft tube, wherein and the spiral tube has an extension line extending without bending at an end to have directionality in a first direction or second direction, and performing an electrolytic polishing process on the evaporator;
- preparing a partition wall, including:
- preparing a tubular shaft body with a predetermined length and the partition wall configured to have a plate shape extending in the first direction and the second direction around the shaft body and form a partition extending in a third direction while forming a plurality of turns of second spirals at a predetermined second pitch;
- assembling a first assembly, including:
- positioning a lower hole of the shaft body on an upper end of the spiral shaft tube, and rotating and assembling the evaporator or partition wall so that the spiral shaft tube passes through the shaft body and the spiral tube passes between the partitions;
- assembling a second assembly, including:
- thermally fusing a flange to a side of the spiral shaft tube and a side of the spiral tube, and assembling the cap to the first assembly so that the spiral shaft tube and the spiral tube pass through the cap and then are exposed to outside;
- and assembling the cold water tank assembly, including:
- inserting and arranging the second assembly into the accommodation space of the body to form the plurality of the heat exchange chambers in the accommodation space of the body.
A cold water tank assembly, comprising:
- a cold water tank including:
- a body configured to have a cylindrical shape with an inlet pipe and an outlet pipe through which purified water flows, said body comprising an accommodation space therein and an entrance expanded in a first direction and second direction, said entrance expanded a predetermined length in a third direction, said body comprising a cap configured to seal the entrance;
- an evaporator through which refrigerant flows, the evaporator configured to include a spiral shaft tube placed in the accommodation space in the third direction, and a spiral tube in which an end of the spiral shaft tube extends in the third direction while forming a plurality of turns of first spirals at a predetermined pitch around the spiral shaft tube;
- and
- a partition wall including:
- a shaft body arranged to surround the spiral shaft tube, and a partition configured to have a plate shape extending in the first direction and the second direction around the shaft body and extend in the third direction while forming a plurality of turns of second spirals at a predetermined pitch,
- wherein an end edge of the partition is arranged closely to an inner circumferential surface of the accommodation space of the cold water tank to form a plurality of heat exchange chambers as a flow path communicating with the inlet pipe and the outlet pipe in the accommodation space in the third direction, and
- wherein the spiral tube is arranged to pass through the plurality of heat exchange chambers continuously, and after forming the first spiral, an extension line thereof that extends without bending for the end to have directionality in the first direction or second direction is exposed to the outside of the cold water tank.
