HEAT EXCHANGE TYPE COOLING DEVICE
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.
1 . A heat exchange type cooling device comprising:
an enclosure partitioning between an inside and an outside;
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, the outside-air passage being independent from the inside-air passage;
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 heater being provided upstream of the heat-exchanging element in the inside-air passage.
2 . The heat exchange type cooling device of claim 1 , wherein the inside-air blower sends the inside air in an airflow direction; and
the heater has an airflow surface arranged perpendicularly to the airflow direction.
3 . The heat exchange type cooling device of claim 1 , wherein the heater includes a first heating element and a second heating element having characteristics different from each other.
4 . The heat exchange type cooling device of claim 3 , wherein
the inside-air blower sends the inside air in an airflow direction; and
the first heating element and the second heating element have airflow surfaces arranged perpendicularly to the airflow direction.
5 . The heat exchange type cooling device of claim 3 , wherein
the first heating element includes
a first heating body, and
a first holder holding the first heating body, and
the second heating element includes
a second heating body, and
a second holder holding the second heating element.
6 . The heat exchange type cooling device of claim 5 , wherein the second holder has a structure identical to a structure of the first holder.
7 . The heat exchange type cooling device of claim 5 , wherein the second heating element has a structure identical to a structure of the first heating element.
8 . The heat exchange type cooling device of claim 1 , wherein the heater includes
a heating body, and
a thermal fuse operating according to a temperature of the heating body.
9 . The heat exchange type cooling device of claim 8 , wherein
the heating body has an airflow surface, and
the thermal fuse is positioned near the airflow surface.
10 . The heat exchange type cooling device of claim 1 , further comprising a thermolabel having an appearance changing according to a temperature of the heater.
