<p>PURPOSE: A natural cooling heat exchanger is provided to maintain temperature in a communication room to a set point without large amount of power consumption because a process is repetitively proceeded that heated air in the room is naturally cooled through a natural cooler in the outside and then the cooled air is supplied to the inside. CONSTITUTION: A natural cooling heat exchanger comprises a fan(10), a natural cooler(20), a blower(30), and a thermostat(40). The fan delivers heated air in a communication room installed all kinds of communication devices to the natural cooler. The natural cooler cools the heated air in a natural cooling system. The blower supplies the natural cooled air in the natural cooler into the room in order to decrease indoor temperature. The thermostat measures the indoor temperature and operates the fan and blower if the indoor temperature is exceeded the set temperature.</p> |
