Detailed ways

Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

In the present invention, in the case of no contrary description, the used orientation words such as "up, down, left and right" usually refer to the up, down, left and right shown in the accompanying drawings; "inside and outside" Refers to the inside and outside of the outline of each part itself.

When using a weak current cabinet, dust will inevitably enter the cabinet 1 through the air inlet P. The inventors of the present invention have learned through research and analysis that in the prior art, although the heat dissipation air flow should follow the flow route from the air inlet P to the fan 5 in theory, in fact a stream of circulating air will be formed at the height of the fan 5 . Since dust is entrained in the cooling air flow, part of the dust also flows with the circulating air at the height where the fan 5 is located, that is, the height where the electrical component 8 is located. During the process of dust circulation, it will inevitably contact or collide with the electrical components 8, and thus adhere to the electrical components 8, resulting in a decrease in the cleanliness of the electrical components 8 and an increase in failure rate.

In order to solve the above problems, the present invention provides a weak current cabinet, which includes a cabinet body 1 and a fan 5 installed on the cabinet body 1, wherein the position of the cabinet body 1 opposite to the fan 5 A tuyere 4a communicating with the outside is provided on the top, so that an air convection area is formed in the weak current cabinet through the fan 5 and the tuyere 4a.

The air convection area is formed in the weak current cabinet through the fan 5 and the tuyere 4a, so that the generation of circulation can be avoided while realizing heat dissipation through the convective air. The dust in the weak current cabinet and the environment can move linearly with the convective air, thereby avoiding the circulation of dust and reducing the chance of dust contacting and colliding with the electrical components 8, so that the weak current cabinet and the electrical components 8 inside are kept clean and in good operating condition .

Wherein, the fan 5 and the tuyere 4a can be arranged at any appropriate relative position of the cabinet body 1 as long as an air convection area can be formed in the cabinet body 1 .

Preferably, the fan 5 can be installed on the top wall of the cabinet 1, and the tuyere 4a can be arranged at the bottom of the cabinet 1, thereby providing air convection from top to bottom in the cabinet 1, So that the electrical components 8 in the whole cabinet 1 are sufficiently cooled. Since the electrical components 8 are mainly arranged on the upper part of the cabinet body 1, this arrangement can increase the range of air flow in the cabinet body 1 and the heat dissipation space, so as to keep the temperature and heat in the cabinet body 1 low.

In addition, the fan 5 can be installed on the top wall of the cabinet body 1 in various appropriate ways, as long as it can be installed on the top wall and exchange airflow with the outside. Preferably, as shown in FIG. 2 , the top wall 3 of the cabinet body 1 may have an installation groove 3 a for installing the fan 5 .

Those skilled in the art can understand that the tuyere 4a can be arranged at any suitable position on the bottom of the cabinet body 1 as long as it can form an air convection area together with the fan 5 . For example, the tuyere 4a may be disposed on the bottom wall 4 of the cabinet body 1 .

In addition, the weak current cabinet can include electrical components 8 installed on the upper part of the cabinet body 1, so as to be close to the fan 5, so as to rapidly cool down under the cooling effect of the fast-flowing airflow near the fan 5.

Wherein, the fan 5 may be various types of fans, for example, for blowing air into the cabinet 1 or sucking air from the cabinet 1 outside. In a preferred embodiment of the present invention, the fan 5 is used to blow air into the cabinet 1, so that the air flow can drive the dust to move from top to bottom in the cabinet 1, so that the dust is far away from the upper part of the cabinet 1. electrical components8.

More preferably, the weak current cabinet may further include a dust collection device, and the dust collection device is in fluid communication with the interior of the cabinet body 1 through the tuyere 4a. Most of the dust flowing with the convective air can be discharged to the external environment through the tuyere 4a, even if a small part of the dust cannot be discharged, it can be collected together by the dust collection device, which is convenient for centralized follow-up treatment. In addition, the dust collecting device can prevent undischarged dust from rising up and polluting the interior of the cabinet 1 under the action of the airflow.

Wherein, the dust collection device can adopt various appropriate structures, as long as it can collect dust and facilitate subsequent treatment. For example, the dust collection device may be a container (such as a box or a bag) filled with an adsorbent.

In the embodiment shown in FIG. 2 , the dust collection device may include a filter plate 6 disposed at the lower part of the cabinet body 1 .

Wherein, the filter plate 6 can be formed into an appropriate shape and structure, as long as it can allow the airflow entrained with dust to pass through and prevent or inhibit the reverse movement of the dust. For example, in the embodiment shown in Fig. 2, the filter plate 6 forms a sieve plate structure.

In addition, the filter plate 6 can be parallel to the bottom wall 4 of the cabinet body 1, so as to prevent the inclined setting from affecting the air convection. Preferably, the distance from the filter plate 6 to the bottom wall 4 is 1/5-1/3 of the height of the cabinet body 1, so as to ensure sufficient convection and heat dissipation space while providing the dust collection function.

More preferably, the cabinet body 1 includes an openable cabinet door 7 for cleaning the dust collection device. Those skilled in the art can understand that other ways can also be used to clean the dust collection device. For example, an opening communicating with the space below the filter plate 6 may be provided on the side wall 2 of the cabinet body 1 .

The preferred embodiment of the present invention has been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the specific details of the above embodiment, within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, These simple modifications all belong to the protection scope of the present invention.

In addition, it should be noted that the various specific technical features described in the above specific implementation manners may be combined in any suitable manner if there is no contradiction. In order to avoid unnecessary repetition, various possible combinations are not further described in the present invention.

In addition, various combinations of different embodiments of the present invention can also be combined arbitrarily, as long as they do not violate the idea of the present invention, they should also be regarded as the disclosed content of the present invention.
