<p>A cooling device has a cooler provided at at least one side-wall side in a room formed by heat-insulated box bodies, a cooling room in front of the cooler, and a fan for causing air in the cooling room to flow. The cooler and the cooling room are partitioned by a partition plate so that cold air collects in the cooler. The fan is provided closer to the cooler than the partition plate, the partition plate in front of the fan has an opening. The size of the opening is greater than the diameter of the fan. When viewed in the direction of its rotation axis, the fan is installed in the opening and there is an open space outside the fan. The rotation of the fan produces a discharge flow of cold air blown from the cooler through the opening to the cooling room and a suction flow of cold air sucked from the cooling room through the opening to the cooler. This causes the discharge flow and the suction flow to collide with each other. As a result the cold air in the cooling room and the cold air collecting in the cooler are exchanged so that a cold air flow speed is held back and the cooler is kept from frosting.</p> |
