[0002] The power cabinet, as a backup power system or power recovery system, generates heat when its internal components are in operation. It is usually necessary to use heat dissipation equipment to discharge the internal heat in time to avoid component failure caused by excessive internal temperature.

[0003] A high-temperature resistant and safe indoor power cabinet is disclosed in a Chinese utility model patent with announcement number CN205452824U. When the temperature is too high, the high-temperature warning module on the control panel will receive a signal. At the same time, the solenoid valve controller on the control panel will control the solenoid valve to operate, and the dry powder fire extinguisher box will spray dry powder through the powder outlet pipe, effectively preventing fire in the power cabinet.

The design of the dustproof net prevents external insects from entering the power cabinet.

[0028] An air pump 8 and an air intake manifold 7 are installed at the top of the cabinet 1. The air outlet of the air pump 8 is connected to the air intake manifold 7 through a pipeline, and the air intake manifold 7 is respectively connected to the tops of multiple injection pipes 5 through multiple hoses 71. The airflow generated by the air pump 8 is transported to each injection pipe 5 through the air intake manifold 7, and then enters the interior of the cabinet 1 through the air holes 51, and cools the components therein to take away the heat.

[0029] The outer surface of the horizontal tube 52 is provided with a plurality of equally spaced extension tubes 53 toward the left, and a plurality of evenly distributed air holes 51 are opened on the extension tube 53. The end of the horizontal tube 52 away from the air injection tube 5 is blocked, and the right end of the extension tube 53 is connected to the horizontal tube 52, and the other end is blocked. The airflow in the air injection tube 5 can enter the horizontal tube 52 and the extension tube 53 and flow out upward, which can make the airflow at the bottom flow upward, so as to cool the components therein.

[0030] Three equally spaced support frames 12 are provided at the bottom of the cabinet 1. The support frames 12 are provided with a plurality of evenly distributed screw holes from top to bottom. An electrical board 3 is mounted on the front side of the three support frames 12 by screws, and a distance of 1-3 cm is provided between the rear surface of the electrical board 3 and the outer surface of the air jet pipe 5. Various components in the power cabinet are mounted on the electrical board 3. The airflow blown out from the air jet pipe 5 on the rear side cools the components on the front side, and the airflow can flow to both sides to take away the heat.

[0031] The rear end opening design of the cabinet 1 forms a rear opening 11, in which a rear plate 13 is installed by screws, and the outer ring surfaces of the plurality of air injection pipes 5 are in contact with the surface of the rear plate 13, which is convenient for the installation of internal components and the arrangement of circuits, and also for subsequent maintenance.

[0032] A base plate 4 is installed at the bottom end of the cabinet 1, and a plurality of air outlets are opened on the base plate 4, and the number and position of the plurality of air outlets correspond one to one with the number and position of the air holes 51 on the horizontal tube 52 and the extension tube 53.

[0034] The implementation principle of a high temperature protection device for a power cabinet in the embodiment of the present application is as follows: in actual use, a corresponding number of electrical panels 3 are installed on three support frames 12 according to actual conditions, and there is a certain space between every two adjacent electrical panels 3. Components are installed on the electrical panels 3. In normal use, the airflow generated by the air pump 8 enters into the multiple jet pipes 5 through the air intake manifold 7. Since the surface of the jet pipe 5 is provided with multiple air holes 51, the airflow inside it will diffuse and blow out through the air holes 51, thereby being able to cool down the components on the front side, and the horizontal pipe 52 and the extension pipe 53 arranged at the bottom will also blow out cold airflow, which will generate flow and cool down the components. The exhaust fans 9 at the left and right ends will make the internal airflow flow outward and discharge, which makes the airflow at the top and the bottom flow toward the middle position, thereby cooling it as a whole to prevent the temperature from rising.

[0035] By arranging a plurality of jet pipes 5, a horizontal pipe 52, and an extension pipe 53 inside the power cabinet, in conjunction with the air intake manifold 7 and an air pump 8, high-speed airflow can be ejected from the rear end and the bottom end inside the power cabinet, thereby blowing air to the internal components and cooling them down;

[0036] By arranging the exhaust fan 9 in the middle of the left and right sides of the power cabinet, the exhaust fan 9 can make the internal airflow diffuse and discharge outward, so that the airflow ejected from the jet pipe 5, the horizontal pipe 52 and the extension pipe 53 can flow toward the middle of the two sides, thereby cooling it as a whole, preventing the temperature from rising and improving safety.

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
