[0039] The power distribution cabinet generates a large amount of heat when working. If the heat is not dissipated in time, the heat will accumulate in the cabinet, causing the temperature to rise, which may cause equipment failure or even fire and other safety hazards. The radiator plays an important role in the stable operation of the power distribution cabinet. The existing radiator usually includes a heat dissipation fin and a fan. The heat dissipated by the power distribution cabinet is absorbed by the heat dissipation fin, and then the fan sucks air to the heat dissipation fin to absorb the heat on the radiator to complete the heat dissipation of the power distribution cabinet. It can also blow air to the heat dissipation fin to blow away the dust on the heat dissipation fin to complete the cleaning of the heat dissipation fin. However, the air volume and wind force of the fan of the current radiator blowing air to the heat dissipation fin are difficult to control, which makes it difficult to meet the requirements of the air volume and wind force for blowing or sucking air on the radiator, resulting in poor heat dissipation effect and poor cleaning effect on the heat dissipation fin.

The cover plate 41 is detachably mounted on the top end of the sleeve 31. The fairing 42 is mounted on the cover plate 41 and abuts against the outer wall of the sleeve 31. The two ends of the fairing 42 are respectively an air suction port 421 and an air inlet 422. The air suction port 421 is connected to the air inlet 422, and the air inlet 422 is arranged toward the heat dissipating fins 21. An adjusting baffle 50 is arranged at the air inlet 422. The adjusting baffle 50 can move relative to the fairing 42 to adjust the size of the air inlet 422.

[0042] Vertical Figure 1 The up and down directions in .

[0043] The technical solution of the present invention is to respectively install a cooling structure 30 and a heat dissipation structure 20 on the heat dissipation position 12 and the installation position 11 on the base 10. The heat dissipation fins 21 in the heat dissipation structure 20 can efficiently absorb the heat in the distribution cabinet, and then the heat on the heat dissipation fins 21 can be absorbed by the fan 33 in the cooling structure 30 to achieve heat dissipation of the distribution cabinet. Further, the cooling structure 30 includes a sleeve 31 and a fan 33, the sleeve 31 extends in the up-down direction, a wind cavity 32 is formed in the sleeve 31, the fan 33 is installed in the wind cavity 32, a vent 34 is opened on one side of the sleeve 31 in the horizontal direction, a cover plate 41 is installed on the top of the sleeve 31, a fairing 42 is connected to the cover plate 41, the fairing 42 extends in the horizontal direction, and the fairing 42 is respectively formed with an air inlet 422 and an air suction port 421 at both ends of the extension direction thereof, when the cover plate 41 is installed on the top of the sleeve 31, the air suction port 421 is connected to the vent 34, and the air inlet 422 is arranged toward the heat dissipation fin 21.

And the size of the air inlet 422 can be adjusted by the adjustment baffle 50 arranged at the air inlet 422.

[0044] It should be noted that the forward rotation of the fan 33 can generate wind that is sucked into the air cavity 32 from the air inlet 422 through the air suction port 421 and the vent 34, thereby absorbing the heat on the heat dissipating fins 21; the reverse rotation of the fan 33 can cause the wind to be blown out from the air cavity 32 through the vent 34 and the air suction port 421 and out from the air inlet 422, thereby blowing off the dust on the heat dissipating fins 21 and completing the cleaning of the heat dissipating fins 21.

[0045] In one embodiment of the present invention, the adjustment baffle 50 can be lifted and lowered at the air inlet 422, and the heat dissipation device 100 also includes a lifting structure 60, which is installed on the cover plate 41, and the lifting structure 60 is used to drive the adjustment baffle 50 to lift and lower vertically relative to the fairing 42 to adjust the size of the air inlet 422.

[0046] Specifically, a lifting structure 60 is provided on the cover plate 41, and the lifting structure 60 drives the adjusting baffle 50 to rise and fall relative to the fairing 42 in the up and down directions, so that the position of the adjusting baffle 50 at the air inlet 422 can be changed in the up and down directions to change the shielding area of ​​the air inlet 422 by the adjusting baffle 50, thereby completing the adjustment of the size of the air inlet 422, and the adjustment is simple and convenient.

[0047] In one embodiment of the present invention, the lifting structure 60 includes:

[0048] Driving member 61;

[0049] A transmission assembly 62, the transmission assembly 62 is mounted on the cover plate 41;

[0050] The lifting assembly 63 includes a support rod 631 and a lever 632. The two ends of the lever 632 are respectively a first end 6321 and a second end 6322. The first end 6321 is hinged to the transmission assembly 62, and the second end 6322 is hinged to the adjustment baffle 50. The support rod 631 extends vertically, and the bottom end of the support rod 631 is supported by the cover plate 41. The top end of the support rod 631 is hinged to the lever 632 at a position between the first end 6321 and the second end 6322.

[0051] The driving member 61 is used to drive the first end 6321 to descend or ascend through the transmission assembly 62 , so as to drive the adjusting baffle 50 to ascend or descend vertically relative to the fairing 42 through the second end 6322 .

[0052] Specifically, a support rod 631 extends in the up-down direction on the cover plate 41, and the bottom end of the support rod 631 is connected to the cover plate 41, and the top end of the support rod 631 is connected to a position on the lever 632 between the first end 6321 and the second end 6322. The first end 6321 of the lever 632 is connected to the adjusting baffle 50, and the second end 6322 of the lever 632 is connected to the transmission assembly 62. The driving member 61 drives the first end 6321 to descend or ascend through the transmission assembly 62, and can drive the second end 6322 to ascend or descend, thereby driving the adjusting baffle 50 connected to the second end 6322 to ascend or descend, thereby completing the adjustment of the size of the air inlet 422, and the adjustment is simpler and more convenient.

[0053] In one embodiment of the present invention, the driving member 61 is a fan 33, and the transmission assembly 62 includes a lifting rod 621 and a first power plate 622. A through hole 411 connected to the wind chamber 32 is opened on the cover plate 41. The lifting rod 621 is vertically lifted and lowered through the through hole 411. The top end of the lifting rod 621 is connected to the first end 6321, and the bottom end of the lifting rod 621 extends into the sleeve 31 and is connected to the first power plate 622. The fan 33 is used to blow and suck the first power plate 622 to drive the first power plate 622 and the lifting rod 621 to rise and fall.

[0054] Further, the driving member 61 is a fan 33 in the air cavity 32, the transmission assembly 62 includes a lifting rod 621 and a first power plate 622, a through hole 411 is provided on the cover plate 41, the through hole 411 is connected to the air cavity 32, the lifting rod 621 is penetrated in the through hole 411 along the up-down direction, and the bottom end of the lifting rod 621 extends into the air cavity 32 and is connected to the first power plate 622, and the top end of the lifting rod 621 extends to the top of the cover plate 41 and is connected to the first end 6321 of the lever 632. When it is necessary to absorb heat, the fan 33 rotates forward to generate a downward suction force, which sucks the first power plate 622 downward, and drives the lifting rod 621 and the first end 6321 connected to the lifting rod 621 to move downward, so as to drive the second end 6322 and the adjustment baffle 50 connected to the second end 6322 to rise, thereby increasing the size of the air inlet 422, so as to increase the air volume and more comprehensively absorb the heat of the heat dissipation fins 21. When the heat dissipation fins 21 need to be cleaned, the fan 33 rotates in the opposite direction to generate an upward thrust, pushes the first power plate 622 upward, and drives the lifting rod 621 and the first end 6321 connected to the lifting rod 621 to move upward, so as to drive the second end 6322 and the adjustment baffle 50 connected to the second end 6322 to descend, thereby reducing the size of the air inlet 422, so as to increase the wind force and more effectively blow the dust on the heat dissipation fins 21. It can be understood that, through the lifting rod 621 and the first power plate 622, when the heat dissipation device 100 provided by the present invention needs to dissipate heat or when the heat dissipation fins 21 need to be cleaned, the size of the air inlet 422 can be adaptively adjusted to generate a larger air volume or a larger wind force, thereby meeting the needs of heat dissipation or cleaning the heat dissipation fins 21. The design is ingenious, does not require manual operation by personnel, and is simple and convenient.

When it is necessary to absorb heat, the fan 33 rotates forward to generate a downward suction force, which sucks the second power plate 72 downward and drives the lifting plate 71 to move downward, so as to reduce the area of ​​the vent 34 blocked by the lifting plate 71, thereby increasing the size of the vent 34, so as to further increase the air volume, and absorb the heat of the heat dissipating fins 21 more comprehensively. When it is necessary to clean the heat dissipating fins 21, the fan 33 rotates backward to generate an upward thrust, which pushes the second power plate 72 upward, and drives the lifting plate 71 to move upward, so as to increase the area of ​​the vent 34 blocked by the lifting plate 71, thereby reducing the size of the vent 34, so as to further increase the wind force, and can more effectively blow the dust on the heat dissipating fins 21 off. It can be understood that, through the lifting plate 71 and the second power plate 72, when the heat dissipation device 100 provided by the present invention needs to dissipate heat or when the heat dissipation fins 21 need to be cleaned, the size of the vent 34 can be adaptively adjusted to generate a larger air volume or a larger wind force, thereby meeting the needs of heat dissipation or cleaning the heat dissipation fins 21.
