  • Patent number: 9080809
    Abstract: A cooling device of the present invention, includes: a cooler provided on at least one side-wall side of a chamber formed with a thermal insulating box; a cooling chamber in front of the cooler; and a fan that allows air in the cooling chamber to flow. The cooler and the cooling chamber are partitioned by a partition so as to allow cold air to be accumulated in the cooler, the fan is disposed on a side of the cooler relative to the partition, the partition in front of the fan has an aperture, and cold air accumulated in a space inside the partition and hot air in the cooling chamber are exchanged by the fan through the aperture. Thereby, a cooling device with a simple configuration and excellent cooling performance can be provided, by which the amount of frost deposited on a cooling coil can be reduced and the miniaturization of the device can be realized.
