Title:
GRAIN REFRIGERATOR FILLED COOLING AID TO HAVE IMPROVED COOLING EFFICIENCY
Document Type and Number:
WIPO Patent Application WO/2021/167316
Kind Code:
A1
Abstract:
The present invention relates to a grain refrigerator, which: has a cooling unit in which the internal space is filled with a cooling aid, and since the cooling aid has a high thermal capacity and thermal conductivity, cooling efficiency increases because of increasing cooling efficiency of the cooling unit, and cooling air can be maintained for a predetermined amount of time even when a current supplied to the cooling unit is cut off, and thus, even though a separate cooling device does not have to be provided, the temperature of the inside of a grain storage barrel can be cooled down to a preset temperature even without additionally providing the separate cooling device, thereby reducing the total volume and cost of the grain refrigerator; and, when moisture formed in the internal space of the cooling unit is discharged to the outside thereof, allows the discharge moisture to be discharged along a heat-dissipating plate structure in a heated state, so that the discharge moisture is heated by means of the heat-dissipating plate structure so as to be discharged in a gas phase, and thus, since a separate moisture discharge means does not have to be provided, volume can be reduced.
