working principle:

First, the device is moved by the universal wheel 19. When moving to the designated work place, when the electrical cabinet is working, the second temperature sensor 9 can sense the temperature in the rectangular box 1. If the temperature is not high, no When heat dissipation is required, the electrical components in the device will not work, thereby saving electric energy. Afterwards, the volatile liquid 4 in the rectangular box 2 needs to absorb the heat in the rectangular box 1 to form natural heat dissipation. The volatile liquid 4 can For ethanol and other liquids, the semicircular grooves on both sides of the rectangular box body 2 can better hang the wall and absorb heat better. When the volatile liquid 4 is volatilizing, the wall hangs in half The inside of the circular groove will absorb heat for a second time to volatilize, and then when the second temperature sensor 9 senses that the temperature is too high, the electrical components in the device start to work. First, the miniature electric control push rod 15 in the sliding part drives the slider 16 slides up and down, thereby driving the blowing fan 5 on the mounting plate 6 to slide up and down, the blowing fan 5 will dissipate heat from the equipment, and when the first temperature sensor 7 on the mounting plate 6 senses that the temperature there is too high, it can control the micro electric control The push rod 15 stops pushing, and the power of the blowing fan 5 is increased to achieve the effect of efficient heat dissipation. Afterwards, the suction fan 8 will extract the hot air in the rectangular box 1. Since the hot air flows upward, the suction fan 8 is set On the upper surface of the rectangular box 1, it can’t effectively cool down the temperature. It can reach the water-cooled radiator 11, then blow the air through the fan 12, and then enter the inside of the rectangular box 1 through the ventilation hole 13, and then the third fan 21 pumping cold air into the duct 17, the cold air flows downward, will be sucked in by the third fan 21, and then blown out through the duct 17 through the lower surface of the rectangular box 1 to achieve efficient heat dissipation. The brake pads 20 can Fix to the wheel 19 to avoid shaking, and then the dust protection net 18 can prevent dust and debris from entering the inside of the device.
