Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses dustproof high heat dissipation type switch board. Referring to fig. 1 and 2, the power distribution cabinet includes a cabinet body 1 and a cabinet door 2 hinged to the cabinet body 1. The position that is close to the roof inside the cabinet body 1 fixedly connected with baffle 3, cavity 4 is formed between the roof of baffle 3 and the cabinet body 1, has seted up exhaust hole 31 in the middle of the right of baffle 3, and exhaust hole 31 vertically runs through whole baffle 3 to install exhaust fan 32 in exhaust hole 31 department. Air outlet holes 11 communicated with the cavity 4 are respectively arranged on the four side walls of the cabinet body 1.

When the inside more steam that produces of cabinet body 1 need discharge, start exhaust fan 32 with the inside steam discharge of cabinet body 1 to cavity 4 in, the steam that gets into in the cavity 4 can discharge along venthole 11 all around to can discharge the steam of the cabinet body 1 inside effectively. Because the hot air has the characteristic of automatically floating upwards, the hot air entering the cavity 4 cannot reversely flow along the air exhaust hole 31 and return to the inside of the cabinet body 1, and the effect of exhausting the hot air can be further improved.

The outer wall of the cabinet body 1 is provided with a first filter plate 12 covering the air outlet holes 11 at the positions of the air outlet holes 11, and the first filter plate 12 is fixedly connected with the cabinet body 1 through bolts. Through setting up first filter 12 can avoid among the bold debris gets into cavity 4, also has certain dustproof effect simultaneously. When the first filter 12 is full of dust and needs to be cleaned, the first filter 12 can be taken down through the loose bolts, so that the first filter 12 can be cleaned and replaced conveniently and quickly.

Still fixedly connected with is curved weather shield 5 at the top of the cabinet body 1, and the border of weather shield 5 all protrudes in the lateral wall setting of the cabinet body 1, can shelter from the rainwater through setting up weather shield 5 to can reduce among rainwater entering cavity 4, can play waterproof effect.

In order to better discharge the hot air in the cabinet body 1, a plurality of uniformly distributed heat dissipation holes 13 are respectively formed in two adjacent side walls of the cabinet body 1 adjacent to the cabinet door 2, the outer side wall of the cabinet body 1 is fixedly connected with a shell 6 covering the heat dissipation holes 13, and the bottom of the shell 6 is open.

Through setting up louvre 13 can further discharge the steam of the internal portion of cabinet 1 to promote the radiating effect of the cabinet body 1. Inside steam that carries out the emission along louvre 13 can get into casing 6 to finally discharge along the opening part of casing 6 bottom, can cover louvre 13 through setting up casing 6, thereby can avoid rainwater and dust etc. to get into the cabinet body 1 inside along louvre 13, can protect the equipment and the cable of the internal portion of cabinet, prevent the electric leakage, promote the security performance of switch board.

Referring to fig. 3 and 4, a second filter plate 61 covering the opening is disposed at the bottom opening of the housing 6, slide rails 62 are fixedly connected to both side walls of the housing 6, and the second filter plate 61 is slidably connected to the slide rails 62. The second filter plate 61 can reduce dust from entering the housing 6, and ensure gas circulation. The second filter plate 61 is slidably inserted into the housing 6, so that the second filter plate 61 can be conveniently mounted, dismounted and replaced.

The implementation principle of a dustproof high heat dissipation type switch board of this application embodiment does: when more hot air is generated in the cabinet body 1 and needs to be discharged, the exhaust fan 32 is started, part of the hot air can be discharged into the cavity 4 after the exhaust fan 32 is started, and the hot air entering the cavity 4 can be discharged along the air outlet hole 11; in addition, partial hot gas can enter the shell 6 along the heat dissipation holes 13, and the hot gas entering the shell 6 can be discharged along the opening at the bottom of the shell 6, so that the hot gas inside the cabinet body 1 can be sufficiently discharged, and the heat dissipation performance of the cabinet body 1 is ensured.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
