Embodiment 1

[0043] Such as Figure 1-Figure 2 , Figure 4 As shown, an improved structure of an electrical cabinet includes a cabinet body 1 and a cover plate that cooperate with each other, and two L-shaped baffles 2 are symmetrically arranged inside the cabinet body 1, and the two sides of the L-shaped baffles 2 The ends are respectively connected to two adjacent side walls of the cabinet 1, and the two L-shaped ends of the L-shaped baffle 2 are respectively in contact with the top wall and the bottom wall of the cabinet 1, and the L-shaped baffle 2 A buffer cavity 3 is formed between the cabinet body 1, and the airflow entering through the air inlet pipe 4 is buffered in the buffer cavity 3. A number of ventilation holes 21 are provided on the side of the L-shaped baffle 2 perpendicular to the air intake direction. , the ventilation holes 21 are only arranged on the side perpendicular to the air inlet direction, which can avoid the reduction of the buffering effect caused by the venti...

Embodiment 2

[0047] Such as Figure 1-Figure 3 As shown, this embodiment is based on Embodiment 1, and the drying device 5 includes a housing 52, two ends of the housing 52 are provided with installation pipes 51, and a drying plate 53 is arranged inside the housing 52, and the drying plate 53 is an arc-shaped plate protruding toward the air inlet; two drying plates 53 are arranged in parallel in the housing 52; the drying plate 53 is a mesh-like drying structure, including a filter screen and a desiccant.

[0048] In this embodiment, by making the drying plate 53 an arc-shaped plate protruding toward the air inlet end, the airflow entering the housing 52 can be guided to diffuse, improve the uniformity of the airflow contacting the drying plate 53 and reduce the airflow in the air. Velocity in housing 52.

Embodiment 3

[0050] Such as Figure 1-Figure 3As shown, this embodiment is based on Embodiment 2, and both ends of the drying plate 53 are provided with protrusions 54, and the inner wall of the housing 52 is provided with a slot that cooperates with the protrusion 54, and the protrusion 54 is inserted into the slot The detachable connection between the drying plate 53 and the housing 52 is realized. The housing 52 includes a matching installation frame and a cover plate, and the cover plate is detachably connected with the installation frame.

Abstract

The invention discloses an improved structure of an electrical cabinet. The improved structure comprises a cabinet body and a cover plate that cooperate with each other. Two L-shaped baffle plates aresymmetrically arranged in the cabinet body; buffer cavities are formed between the L-shaped baffles and the cabinet body; a plurality of vent holes are formed in the side face, perpendicular to an air inlet direction, of each L-shaped baffle. Air inlet pipes are arranged on two symmetrical side walls of the cabinet body; the air inlet pipes are communicated with the buffer cavities; the air inletpipes are provided with air inlet fans, the top of the cabinet body is provided with an air exhaust pipe, the air exhaust pipe is provided with an exhaust fan, and the air inlet pipe is provided witha drying device. According to the invention, problems that due to the fact that an existing electrical cabinet is provided with through holes for heat dissipation, heat dissipation is not uniform, and use of electronic components is affected by introduction of humid airflow are solved.

Description

technical field [0001] The invention relates to the technical field of electric control cabinets, in particular to an improved structure of an electric cabinet. Background technique [0002] Electrical cabinets (switch cabinets) are commonly used electrical equipment, which are used to support and protect internal electronic components and switching components (electrical components). Electrical cabinets are usually machined from steel. [0003] At present, the existing electrical cabinet includes a cabinet body and a cover plate that cooperate with each other. After the electrical components are installed in the cabinet body, they are closed through the cover plate to prevent the electrical components from being exposed to the outside, which is beneficial to the protection of the electrical components. [0004] The components in the electrical cabinet will emit a lot of heat when they are working. These heats are often unable to be discharged due to the support plate and t...
