Abstract

The present invention relates to an enclosure (100) having an eco-friendly cooling structure that accommodates electrical equipment and effectively releases internal heat using outside air. The enclosure (100) includes a rectangular roof section (10) and an equipment storage section (20), and the equipment storage section (20) includes a ceiling section (23), a floor section (24), and four standing wall sections (22). According to the present invention, the device storage unit (20) is mounted on a base frame (30) made of a channel steel (31) in which the base portion (32) is open horizontally outward, and cold air from the outside is introduced through the external air inlet hole (33a) of the base frame (30) and the external air inlet hole (24a) of the bottom portion (24). The introduced cold air rises through the discharge pipe (12) of the roof portion (10), where negative pressure is formed by Bernoulli's principle, and is discharged to the outside, thereby effectively cooling the device storage unit (20) naturally. In addition, external air circulation through the convection passage space (S3) formed between the inner plate (22A) and the outer plate (22B) of the upright wall portion (22) and additional internal space (S2) cooling through the louver-shaped perforated plate (26) of the inner plate (22A) are possible. In particular, the standing wall section (22) is fixed by a spacer (25) comprising a nut section (25a) integrally formed on the inner plate (22A) and a bolt (25b) that penetrates the outer plate (22B), thereby effectively preventing internal intrusion of wind and rain. In addition, when multiple hulls (100) are arranged side by side on a concrete base (1), the hulls can be stably joined in a horizontal position using a channel-type bridge bracket (50) and an angle-type bracket (60), thereby achieving excellent seismic performance. This structure effectively solves the problems of cooling efficiency, operating costs, maintenance, wind and rain intrusion, and stability when multiple hulls are installed in the existing hulls.

Description

Box having eco-friendly cooling structure The present invention relates to an enclosure having an eco-friendly cooling structure that accommodates electrical equipment and effectively releases internal heat using external air. Generally, electricity generated at a power plant is stepped up to a high voltage of 154,000 kV suitable for transmission and transmitted to a primary substation, where the supplied voltage is lowered to 22,900 kV and supplied to a secondary substation and each consumer. As such, switchboards are used as electrical equipment to safely supply high-voltage electricity transmitted from power plants to the receiving facilities of each consumer. These switchboards typically form a box-shaped enclosure and are installed on a foundation, such as a concrete structure, at specific locations on the ground or where power supply is required, while remaining isolated from the outside. Furthermore, as electricity consumption increases daily and electrical equipment becomes larger and more advanced, such switchgear is becoming relatively larger; additionally, to accommodate the diversification of electricity usage, there is a trend to incorporate receiving, transformer, distribution, rectifying, circuit breaker, and outlet sections. However, as the capacity of the electrical devices equipped in the switchgear increases and becomes more complex, the amount of heat generated by the electrical equipment installed inside becomes very high, causing the internal temperature to rise. If proper heat is not released when the temperature inside the switchgear rises, the devices built inside the switchgear may melt, which can lead to a power outage. Conventional switchgear has the problem of this vulnerability, which reduces the stable supply of power to consumers. A switchboard for solving these problems is disclosed in Korean Patent Registration No. 10-1033096. The housing of the switchgear disclosed above draws outside air into the switchgear solely by the force of the fan blades and discharges it back outside the switchgear after passing through the blades; consequently, the fan operates all day long during the summer, leading to increased operating costs and rapid deterioration of the fan, which requires frequent replacement. To solve this problem, a method is being considered to equip the enclosure of the switchboard with a sensor to detect the internal temperature and to activate the ventilation fan when a predetermined temperature is detected by the sensor; however, this method has the problem that once the interior of the switchboard enclosure rises to a predetermined temperature, it is difficult to quickly lower that temperature by the ventilation fan because the enclosure is already heated. An enclosure for solving these problems is disclosed in Patent No. 10-1362736, which was patented by the applicant. In the above-described modified enclosure, there is a roof section and an equipment storage section, and an external air passage space circulating with the internal space of the equipment storage section exists within the roof section, and an entrance for external air to enter and exit is provided on the front and rear undersides of the roof section that protrudes outward from the enclosure than the front and rear upright walls among the four upright walls of the roof section fixed to the tops of the four upright walls of the equipment storage section, and ventilation holes are formed in the four upright walls of the roof section, and a rainwater intrusion prevention louver inclined from top to bottom is provided in the ventilation holes to prevent rainwater from entering the internal space of the enclosure through the ventilation holes, and the four upright walls of the equipment storage section are arranged such that a flat inner plate and a corrugated outer plate are arranged such that the inner plate protrudes further downward relative to the outer plate and the outer plate protrudes further upward relative to the inner plate, and these are stacked and fixed by riveting, etc., and a through hole for external air to enter and exit is formed in the lower part of the inner plate, and to prevent foreign substances contained in the external air from entering and exiting the enclosure through the through hole A filter is included for this purpose. However, in the enclosure disclosed above, the ventilation openings of the four upright walls of the roof section are equipped with louvers that are inclined from top to bottom to prevent rainwater intrusion, so the outside air does not enter and exit the interior of the roof section smoothly, and there is a limit to how much the pressure head can be lowered due to the entry and exit of outside air, so the air inside the equipment storage section cannot be easily exhausted through the roof section, and thus there is a problem with heat dissipation of the enclosure through ventilation. An enclosure for solving these problems is disclosed in Patent No. 10-1637
