Abstract:
A cooling device comprising a thermal insulating box, a cooling coil part of a cooling coil disposed on at least one inner wall of the thermal insulating box, a fan arranged in front of the cooling coil part, and a cooling chamber as a space in front of the fan, where the fan discharges air into the cooling chamber to flow therein, whereindry cooling air in the cooling coil part is sucked from a rear side of the fans and discharged into the cooling chamber; air returning from the cooling chamber is divided into a first air volume corresponding to a volume of sucked air passed through the cooling coil part that is fed from the cooling chamber to the cooling coil part through areas not occupied by the cooling fan, and a second air volume that heads directly for the rear of the fan, wherein most of the air returning from the cooling chamber directly heads for the rear of the fan; and a speed at which the airflow is fed is set so as to permit vapor generated in the cooling chamber to solidify before the vapor is brought into contact with the cooling coil.
