The device can cool each device independently, so that the cooling effect is better.

[0015] 3. Cold air comes out of the wind bin and enters the guide bin through the air inlet. The guide plate makes the cold air flow out from the two air outlets and enter the air outlet duct, and then enter the cooling pipe from the air outlet duct. By turning the adjustment lever, the screw rod rotates, so that the two sliders move closer or farther away, so that the cold air enters the cooling pipe in the area formed by the opposite surfaces of the two sliders, and then flows out from the air outlet nozzle. The closer the two sliders are, the fewer cooling pipes the cold air can enter. The number of cooling pipes that the cold air enters can be adjusted according to the upper surface area of ​​the electrical equipment, so that the area covered by the blown cold air is equivalent to the upper surface area of ​​the electrical equipment, reducing the area where the cold air is blown out of the electrical equipment.
