In addition, a temperature sensor 18 for sensing the internal temperature of the inner housing 10 is installed. Furthermore, a control panel capable of controlling the operation of the pump 13 by determining the temperature signal sensed by the temperature sensor 18 may be installed.

The outer enclosure 20 is provided with a door 21 that can be opened and closed on the front side, and a space for accommodating the inner enclosure 10 is provided. A cooling water tank 30 for storing a predetermined amount of cooling water is installed in the lower portion of the outer enclosure 20 . The cooling water tank 30 is piped with the pump 13 of the inner housing 10 to supply water. In addition, a supply hose 15 for supplying the coolant pumped from the coolant tank 30 by the pump 13 of the inner casing 10 to the upper portion of the inner casing 10 is connected to the outer casing 20 . And at the end of the supply hose 15 , the injection pipe 16 for spraying through the injection nozzle 17 to the upper end of the inner housing 10 is installed at the inner upper end of the outer housing 20 .

In addition, a plurality of inlet holes 22 are formed in the upper end surface or the side cross-section of the outer housing 20 . The inlet hole 22 is a through hole through which rainwater flows in. A drain hole 23 is formed in the lower front of the outer enclosure 20 . The drain hole 23 is to discharge to the outside when the rainwater introduced from the outside is greater than a certain amount.

The cooling water tank 30 may have an insulating material applied thereto. A water level sensor 32 is installed in the coolant tank 30 to detect the amount of coolant stored therein, and a liquid sensor 33 for detecting coolant supplied to the upper end of the coolant tank 30 is installed. In addition, an opening/closing member 31 that opens and closes to store coolant into the coolant tank 30 by a detection signal of the liquid sensor 33 may be installed at the upper end of the coolant tank 30 .

The opening/closing member 31 is opened when the operation of the pump 13 is started under the control of the controller 12, and is closed after a predetermined time when the operation of the pump 13 is stopped. In addition, when the water level of the cooling water tank 30 is below the set water level in a state in which the operation of the pump 13 is stopped, the controller 12 causes the opening and closing member 31 to be opened with a detection signal from the liquid sensor 33 . This is to be able to supplement the cooling water tank 30 with rainwater flowing in from the outside of the outer enclosure 20 .

Meanwhile, in FIG. 4A , irregularities may be formed in the longitudinal direction on the front and rear surfaces and the left and right surfaces of the inner housing 10 . That is, while the coolant sprayed from the injection pipe 16 flows down from the upper end of the inner casing 10 , it flows down along the recesses of the irregularities 35 formed on the surface of the inner casing 10 . Accordingly, the unevenness 35 formed on the surface of the inner casing 10 induces the flow of cooling water and increases the surface area of the inner casing 10 to improve thermal conductivity. In addition, in FIG. 4B , the cooling fins 36 are coupled to the surface of the inner enclosure 10 , so that the same effect as the unevenness 35 can be predicted.

The CCTV equipment installed in the inner enclosure 10 starts to heat while operating, and heat conduction occurs through the case of the inner enclosure 10 inside the inner enclosure 10 . And the heat conducted to the inner housing 10 is conducted to the outside through the case of the outer housing (20). At this time, in the summer season or on days when the sun is strongly shining, the temperature inside the inner casing 10 is further increased due to the heat generated from the CCTV equipment installed in the inner casing 10 and the external temperature.

Therefore, the temperature sensor 18 installed in the inner housing 10 senses the internal temperature of the inner housing (10). At this time, the controller 12 operates the pump 13 when the temperature sensed by the temperature sensor 18 is equal to or higher than a set temperature, for example, 60° C. or higher. And the controller 12 opens the opening/closing member 31 installed in the cooling water tank 30 together with the operation of the pump 13 . Cooling water is pumped from the cooling water tank 30 installed in the external housing 20 by the operation of the pump 13 and supplied along the pipe, and the pumped cooling water is filtered through the filter 14 .

Cooling water passing through the filter 14 is supplied to the injection pipe 16 through the supply hose 15 .

And the cooling water supplied to the injection pipe 16 is evenly sprayed on the upper end of the inner housing 10 through the plurality of injection nozzles (17). The cooling water sprayed from the injection nozzle 17 cools the surface of the inner casing 10 while flowing down along the surfaces of the front and rear surfaces and the left and right surfaces from the top of the inner casing 10 . When the surface of the inner housing 10 is cooled with the cooling water, the internal temperature of the inner housing 10 is lowered.

The cooling water flowing down from the surface of the inner enclosure 10 falls onto the cooling water tank 30 installed at the lower part of the outer enclosure 20, and the dropped cooling water pools at a certain level while opening and closing the cooling water tank 30 at the upper end of the cooling water tank 30 ( 31) through the open through hole.

In addition, the coolant is mixed with water and volatile ethanol to rapidly cool the surface of the inner housing 10 .

In this way, the coolant pumped from the coolant tank 30 is sprayed on the upper surface of the inner enclosure 10 through the spray nozzle 17 of the spray pipe 16 along the supply hose 15, and the sprayed coolant is the inner casing After passing through the surface of (10), the inner housing (10) is cooled by heat exchange through a circulation process that falls onto the cooling water tank (30) and flows back into the cooling water tank (30).

In addition, when the concave-convex 35 is formed on the surface of the inner housing 10 or the cooling fins 36 are coupled, the cooling water sprayed on the upper surface of the inner housing 10 evenly flows down along the recessed portion for more effective cooling will do

And when the temperature of the inner housing 10 is lowered and the temperature sensed by the temperature sensor 18 is below the set temperature, the controller 12 stops the operation of the pump 13 . And when the set predetermined time elapses, the opening and closing member 31 is operated to close the through hole 37 . That is, the controller 12 closes the cooling water tank 30 to prevent evaporation of the cooling water when the set time elapses for the cooling water sprayed on the surface of the inner enclosure 10 to fall and flow back into the cooling water tank 30 . to make it possible

In addition, the light blocking film 40 installed on the upper end and side of the outer housing 20 prevents the outer housing 20 from being heated by direct sunlight. The inlet hole 22 formed in the outer enclosure 20 allows rain or snow, such as rainwater, to flow into the outer enclosure 20 . Rainwater flowing into the external enclosure 20 is stored in the upper part of the cooling water tank 30, and when the water level in the cooling water tank 30 is below the set water level in a state where the operation of the pump 13 is stopped, the liquid sensor 33 ) by opening the opening/closing member 31 to fill the cooling water tank 30 with rainwater through the through hole 37, so that the cooling water tank 30 can be filled with insufficient cooling water. Rainwater introduced into the outer enclosure 20 is discharged to the outside through the drain hole 23 when the water level is higher than a certain level.

In the present invention, the above embodiment is an example, and the present invention is not limited thereto. Anything that has substantially the same configuration as the technical idea described in the claims of the present invention and achieves the same operation and effect is included in the technical scope of the present invention.
