Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Embodiment 1, according to a drawer-type power distribution cabinet shown in FIGS. 1-5, comprising a box body 1, a fan drawer 2 is arranged at the bottom of the box body 1, a fan 4 is arranged inside the fan drawer 2, and the Both sides of the fan drawer 2 are provided with first sliding rails 5 , one side of the fan drawer 2 is provided with a ventilation port 6 , and a ventilation duct 7 is fixed on the top of the ventilation port 6 , and one side of the ventilation duct 7 is provided with multiple ventilation ports. There are two air inlets 8, the other side of the fan drawer 2 is provided with an air exhaust duct 9, one end of the bottom of the air exhaust duct 9 is provided with an air outlet 10, and the other side of the air exhaust duct 9 is provided with a plurality of air outlets 11. A fixing plate 12 is fixed inside the box body 1, a drawer 13 is arranged on the top of the fixing plate 12, the two side walls of the drawer 13 are set in a mesh shape, and the two sides of the drawer 13 are provided with a second The slide rail 14 and the other side of the drawer 13 are fixedly provided with a baffle plate 16 , and the front side of the drawer 13 is provided with a handle 17 .

Further, the number of the fixing plates 12 and the drawers 13 is set in multiples, and each drawer 13 is provided with an air outlet 11 and an air inlet 8 on both sides respectively, which is beneficial to the circulation of the air inside the box body 1 . .

Further, the two first sliding rails 5 and the second sliding rails 14 are fixedly connected to the inner walls on both sides of the box body 1 , which facilitates the pulling of the drawer 13 .

Further, both the ventilation duct 7 and the exhaust duct 9 are arranged in the side wall of the box body 1, which saves the space of the box body, and at the same time, the ventilation duct 7 and the exhaust duct 9 are not easily damaged.

Further, the plurality of second sliding rails 14 are arranged on the bottoms of both sides of the drawer 13 , which will not affect the circulation of the wind, nor will it affect the baffle 16 to block the air inlet 8 .

Further, the cross-sectional shape of the baffle 16 is set to be L-shaped, and a sealing gasket 15 is fixed on one side of the baffle 16 .

Further, the front edges of the fan drawer 2 and the drawer 13 are provided with a sealing ring 3, which can prevent the wind blown by the fan 4 from spreading to the outside.

The working principle of the utility model: firstly, when the fan 4 is running, because the sealing ring 3 is provided outside the fan drawer 2, the wind blown by the fan 4 will not diffuse to the outside, and the wind will enter the ventilation duct 7 through the ventilation port 6, and pass through the ventilation port 6. The ventilation duct 7 brings the wind force to the air inlet 8, and the wind will blow to the side of the drawer 13 through the air inlet 8, because the side walls on both sides of the drawer 13 are set to be meshed, the wind force will blow to the electronic components through the side wall of the drawer 13, It acts as a heat dissipation function for the electronic components, and then the wind will blow through the other side wall of the drawer 13 to the air outlet 10, and then enter the air outlet duct 9 through the air outlet 10, and finally be discharged from the air outlet 11. The design allows the wind to circulate inside the box body 1, which can have a good heat dissipation effect for the electronic components, because the baffle 16 provided on one side of the drawer 13 drives the baffle 16 to the side of the drawer 13 when the drawer 13 is pulled outward. When the drawer 13 drives the baffle 16 to move, the baffle 16 will move to the position of the air inlet 8, the baffle 16 will block the air inlet 8, and the gasket 15 will block the air inlet 8 more tightly, so that when the drawer 13 is pulled out to check or repair electronic components, the air inlet 8 of that drawer 13 will be closed, while other drawers 13 are still ventilated, avoiding the waste of resources. ;

The ventilation duct 7 and the exhaust duct 9 are arranged in the side wall of the box body, which saves the space of the box 1, and the ventilation duct 7 and the exhaust duct 9 will not be easily damaged. When the fan 4 is damaged, the fan drawer 2 slides out through the first sliding rail 5 , which also facilitates the maintenance of the fan 4 .

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection of the utility model.
