Abstract
An outdoor installation type cabinet which accommodates electronic equipment has a number of thin tubes which form an outside air passage and outside air is allowed to flow in the outside air passage by operating an external fan. A heat exchanger which is spaced from each wall of the cabinet is provided at a midway portion of the outside air passage to perform heat exchange between the outside air flowing in the outside air passage and inside air present in the equipment accommodating portion. A circulating fan is installed in the equipment accommodating portion to circulate the inside air. A bimetal is mounted on each side wall of the cabinet to detect a temperature of each side wall and control operations of the external fan, the circulating fan, and an internal fan according to the temperature detected. If the temperature of one side wall is higher than the temperature of the opposite side wall under given temperature conditions, the operation of only the circulating fan on that one side wall is stopped in to thereby suppress the entry of heat of solar radiation through that one side wall into the cabinet body and simultaneously continue to cool the interior of the cabinet.
