Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
Referring to fig. 1 to fig. 4, an electrical apparatus for assisting heat dissipation of a side cabinet according to the present invention will now be described. The side cabinet auxiliary heat dissipation electrical equipment comprises a power cabinet 1 and a side cabinet 2. The front plate of the power cabinet 1 is provided with an air inlet 11, and the top plate is provided with a first air outlet 12; the side cabinet 2 is arranged on one side of the power cabinet 1, and the inner cavity of the side cabinet is communicated with the inner cavity of the power cabinet 1; the front plate and/or the rear plate and/or the side plate of the side cabinet 2 are/is provided with a second air outlet 21.
A first heat dissipation air duct is formed in an inner cavity of the power cabinet 1, and the first heat dissipation air duct is communicated with the air inlet 11 and the first air outlet 12; a second heat dissipation air duct is formed between the inner cavity of the power cabinet 1 and the inner cavity of the side cabinet 2, and the second heat dissipation air duct is communicated with the air inlet 11 and the second air outlet 21.
The electrical equipment provided by the embodiment is suitable for being applied to the environment of an offshore wind power platform. Because marine air humidity is great, easily produces and congeals fog, in avoiding congealing the fog and getting into power cabinet 1, increase waterproof top cap 3 at the top of power cabinet 1 and side cabinet 2. The waterproof top cover 3 covers most of the first air outlet 12, and the air outlet area of the first air outlet 12 is reduced.
The side cabinet 2 may be any one of a power distribution cabinet, an incoming line cabinet, a communication cabinet, a control cabinet, and the like, and in practical applications, the power cabinet 1 needs to be used with the above-mentioned equipment. In the above devices, no large heating element is provided, and the requirement for heat dissipation is not high. Therefore, after any one of the above devices is integrated with the power cabinet 1, a second heat dissipation air duct can be formed by using the inner cavity of the side cabinet 2, and the second air outlet 21 is formed in the side cabinet 2, so that air is assisted by the second heat dissipation air duct, the air outlet area of the power cabinet 1 can be increased, the air outlet quantity is increased, the heat dissipation efficiency of the power cabinet 1 is effectively improved, and the subsequent power grade improvement of the power cabinet 1 is facilitated.
For example, the inner cavity of the power cabinet 1 is equipped with a plurality of power units 13 sequentially arranged from top to bottom, as shown in fig. 1 to 3, each power unit 13 has a first air duct 14 from front to back; the front end of each power unit 13 is equipped with a heat radiation fan and a filter screen. The heat dissipation fan corresponds to the air inlet 11 in front and back. Each power unit 13 is spaced from the rear plate of the power cabinet 1, and a third air duct 15 is formed at the spacing from bottom to top.
A second air duct 22 is formed in the inner cavity of the side cabinet 2; each first air chute 14 is in communication with a second air chute 22.
The first heat dissipation air duct includes a plurality of first air ducts 14 and a third air duct 15. The second heat dissipation air duct includes a plurality of first air ducts 14 and a second air duct 22.
Air enters the power cabinet 1 from the air inlet 11, is blown by the cooling fan and flows backwards in the first air duct 14, and the components of the power unit 13 are cooled in the flowing process. The hot air after absorbing heat partially flows to the third air duct 15, is discharged from the first air outlet 12, partially enters the second air duct 22, and is finally discharged from the second air outlet 21.
Specifically, the second air duct 22 may be separately disposed in the inner cavity of the side cabinet 2 to avoid components inside the side cabinet 2, or the inner cavity of the side cabinet 2 may be regarded as the second air duct 22 as a whole, and a portion of air passing through the first air duct 14 may enter the second air duct 22 under the action of pressure, and then is discharged through the second air outlet 21.
The first heat dissipation air duct in this embodiment is formed by using the positional relationship of each component of the power unit 13 and the positional relationship between the power unit 13 and the power cabinet 1, and an air duct does not need to be separately provided, so that the structure of the power cabinet 1 is simplified, and the cost is saved.
Since the electrical equipment with the side cabinet for assisting in heat dissipation in this embodiment is suitable for being applied to an offshore wind power platform environment and is limited by an ambient environment, the rear portion of the electrical equipment has no maintenance space, and an air outlet cannot be formed in the rear plate, and in addition, if other machines are placed around the electrical equipment, an air outlet cannot be formed in the side plate, and in such an environment, it is preferable that the second air outlet 21 is formed in the front plate of the side cabinet 2. Therefore, the electrical equipment can be installed close to the wall, the space is saved, and the power equipment adopts a front maintenance mode, so that the installation of parts and the subsequent maintenance operation are convenient.
Preferably, in order to avoid the backflow of the hot wind, the overfire air area of the second wind outlet 21 is defined to be 0.125-0.25 times of the overfire air area of the wind inlet 11, and the transverse distance between the second wind outlet 21 and the wind inlet 11 is greater than 200mm.
The area of the second air outlet 21 is increased, so that heat diffusion is facilitated, and the temperature of outlet air is reduced. However, when the area of the second air outlet 21 is too large, the backflow phenomenon of hot air is serious, and on the contrary, the temperature of the air inlet 11 and the temperature of the components of the power unit 13 are increased, so that the air outlet area of the second air outlet 21 is within a reasonable range, which is beneficial to rapid heat diffusion and can reduce the backflow of hot air.
In addition, the closer the second air outlet 21 is to the air inlet 11, the more serious the hot air backflow is, so the transverse distance between the second air outlet 21 and the air inlet 11 is set to be greater than 200mm.
In addition to the second outlet 21 being disposed on the front plate of the side cabinet 2, if the surrounding space is large and there is no other device impact, the second outlet 21 may be disposed on the side plate of the side cabinet 2 and/or the rear plate of the side cabinet 2.

Because the power cabinet is not influenced by the environment, a third air outlet can be formed in the rear plate of the power cabinet 1. The rear air outlet of the power cabinet 1 needs to guide a part of the hot air to the side cabinet 2, so that an air deflector 16 is disposed in the inner cavity of the power cabinet 1, as shown in fig. 5 and 6, the air deflector 16 is located in front of the third air outlet, the air deflector 16 is inclined with respect to the front-rear direction of the power cabinet 1, and a plurality of air guiding holes are disposed on the air deflector 16 and distributed at intervals.
Part of hot air can directly pass through the air guide hole and then is discharged out of the power cabinet 1 from the third air outlet; part of the hot air is blocked by the air deflector 16, changes the flow direction, enters the side cabinet 2, and is discharged out of the side cabinet 2 from the second air outlet 21.
