Cooling apparatus having increased cooling efficiency
View Patent ↗A cooling apparatus, having increased cooling efficiency, which has a cooling rod passing through the inside of a storage receptacle such that an object to be cooled stored inside the storage receptacle is cooled by means of the cooling rod, and in which the cooling rod or the storage receptacle is filled with an auxiliary cooling solution for increasing the cooling efficiency, thereby cooling the inside of the storage receptacle to a predetermined temperature even in an environment with a high external temperature.
1 . A cooling apparatus comprising a case, a storage receptacle installed inside the case and storing water therein, and a cooling part for cooling the water stored in the storage receptacle,
wherein the cooling part includes:
a cooling rod, an upper end portion of which penetrates a bottom surface of the storage receptacle and protrudes into the storage receptacle, and a lower end portion of which is positioned lower than the bottom surface of the storage receptacle;
a cooling means installed on a lower surface of the cooling rod so as to cool the cooling rod; and
a tube body formed in a tube shape with an upper portion closed and installed to surround the cooling rod,
wherein the tube body is composed of a double wall body with an inner wall and an outer wall,
wherein the tube body includes a first partition plate and a second partition plate, the first and second partition plates spaced apart from each other in the vertical direction inside the tube body,
wherein the tube body has a plurality of through holes formed in the inner wall, the outer wall, and the first and second partition plates, so as to allow water to flow into or out of the tube body.
2 . The cooling apparatus according to claim 1 , wherein the storage receptacle includes partition walls formed to be spaced from each other such that an inner space of the storage receptacle is separated by the partition walls, the partition walls each having a plate shape and containing at least one or more drain holes.
3 . The cooling apparatus according to claim 1 , wherein the cooling means is a thermoelectric element.
