HEAT EXCHANGE TYPE COOLING DEVICE

摘要

A heat exchange type cooling device includes an enclosure, an inside-air passage allowing inside air in the inside of the enclosure to flow through the inside-air passage and returning the flowing inside air to the inside, an outside-air passage allowing outside air at the outside of the enclosure to flow through the outside-air passage and returning the flowing outside air to the outside, an inside-air blower sending the inside air to the inside-air passage, an outside-air blower sending the outside air to the outside-air passage, a heat-exchanging element exchanging heat between the outside air flowing through the outside-air passage and the inside air flowing through the inside-air passage, and a heater for heating the inside air. The outside-air passage is independent from the inside-air passage. The heater is provided upstream of the heat-exchanging element in the inside-air passage. This heat exchange type cooling device can heat and cool the inside of the enclosure while preventing dust and moisture from entering into the inside of the enclosure.
