Detailed Description
The utility model provides a low pressure electrical equipment protector, includes equipment box 1 and air inlet box 2, equipment box 1 sets up box baffle 7 with air inlet box 2 butt joint face, air intake 3 is seted up to box baffle 7, be provided with radiator fan 4 in the air inlet box 2, the both sides face of air inlet box 2 is provided with can open with closed shutter 6, equipment box 1 bottom is provided with air exit 8.
When the equipment is used, the cooling fan 4 of the air inlet box body 2 works, meanwhile, the shutter 6 of the air inlet box body 2 is opened, air enters from the shutter 6 and is discharged through the air outlet 8 at the bottom of the equipment box body 1 to perform cooling; when the device is not in use, the radiator fan 4 is stopped and the shutter 6 is closed. When the heat dissipation device is not used, dust is prevented from entering the box body from the heat dissipation port, and the influence on the normal use of internal devices is avoided. The arrangement of the equipment box body 1 and the air inlet box body 2 can effectively ensure the air speed circulation of air inlet and air outlet, and is favorable for heat dissipation of equipment. The box body partition plate 7 is arranged, so that dust in the air inlet box body 2 to the equipment box body 1 can be effectively received and attached, and the heat dissipation efficiency of the equipment box body 1 is improved.
As shown in fig. 1, 2 and 3, the wind inlet case 2 is provided on the top of the equipment case 1. The area of the bottom surface of the air inlet box body 2 is larger than that of the top surface of the equipment box body 1, and the bottom surface of the air inlet box body 2 covers the top surface of the equipment box body 1 along the extension of the top surface of the equipment box body 1. The box partition 7 is provided with two air inlets 3, and each air inlet 3 is provided with a corresponding heat radiation fan 4. A partition 5 is provided between the two heat dissipation fans 4. The louver 6 is an electric louver. The electric shutter comprises an actuating mechanism 61, a junction box 62, a window 63, a waterproof box 64, a blade 65 and a dustproof net 66, wherein the actuating mechanism 61 and the junction box 62 are arranged in the waterproof box 64, the blade 65 and the dustproof net 66 are arranged on the window 63, the dustproof net 66 is arranged outside the blade 65, and the actuating mechanism 61 drives the blade 65.
When the air conditioner is in use, the heat radiation fan 4 works, the actuating mechanism 61 is electrified, the actuating mechanism 61 opens the blades 65 of the louver window, air enters from the louver window 6 and is discharged through the air outlet 8 at the bottom of the equipment box body 1, and heat radiation is performed. When the radiator fan is not used, the radiator fan 4 stops, the actuator 61 is powered off, the blades 65 of the shutter are automatically reset through the spring in the actuator 61, and the shutter 6 is closed. When the heat dissipation device is not used, dust is prevented from entering the box body from the heat dissipation port, and the normal use of internal devices is prevented from being influenced.
