Outdoor installation type cabinet
First Claim
1. An outdoor installation type cabinet for accommodating electronic equipment, comprising:
- a substantially box-shaped cabinet body having a side wall formed with a plurality of first ventilation openings;
an outside air passage provided in said cabinet body so as to extend between said first ventilation openings of said side wall of said cabinet body;
an external fan for generating a flow of outside air in said outside air passage;
a heat exchanging means provided in said cabinet body so as to be spaced from an inner surface of said side wall of said cabinet body, for performing heat exchange between said outside air flowing in said outside air passage and inside air present in said cabinet body; and
a temperature detecting and controlling means for detecting a temperature of said side wall of said cabinet body and controlling an operation of said external fan according to said temperature detected,wherein said cabinet body has a partition wall formed with a second ventilation opening, said partition wall dividing a space inside of said cabinet body into an upper section as an equipment accommodating portion for accommodating said electronic equipment and a lower section as a battery accommodating portion for accommodating a storage battery;
a portion of said side wall of said cabinet body corresponding to said battery accommodating portion is formed with a third ventilation opening; and
said outside air passage further extends between said first ventilation openings and said second ventilation opening.

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.

6. An outdoor installation type cabinet for accommodating electronic equipment, comprising:
-
a substantially box-shaped cabinet body having a first side wall formed with a first upper ventilation opening and a first lower ventilation opening, and having a second side wall formed with a second upper ventilation opening and a second lower ventilation opening; a first fan accommodating chamber defined in said cabinet body at a position in the vicinity of said first upper ventilation opening of said first side wall of said cabinet body; a second fan accommodating chamber defined in said cabinet body at a position in the vicinity of said second upper ventilation opening of said second side wall of said cabinet body; a first external fan provided in said first fan accommodating chamber so as to discharge air inside said first fan accommodating chamber from said first upper ventilation opening; a second external fan provided in said second fan accommodating chamber so as to discharge air inside said second fan accommodating chamber from said second upper ventilation opening; a first outside air passage provided in said cabinet body so as to extend between said first fan accommodating chamber and said first lower ventilation opening; a second outside air passage provided in said cabinet body so as to extend between said second fan accommodating chamber and said second lower ventilation opening; a first heat exchanging means provided in said cabinet body so as to be spaced from an inner surface of said first side wall, for performing heat exchange between outside air flowing in said first outside air passage and inside air present in said cabinet body; a second heat exchanging means provided in said cabinet body so as to be spaced from an inner surface of said second side wall, for performing heat exchange between outside air flowing in said second outside air passage and said inside air present in said cabinet; and a temperature detecting and controlling means for detecting a first temperature as a temperature of said first side wall and a second temperature as a temperature of said second side wall and controlling operations of said first external fan and said second external fan according to results of comparison of said first temperature detected, said second temperature detected, and a plurality of preset temperatures. - View Dependent Claims (7, 8, 9)
