Specifically, cabinet body includes door-plate 310, backboard 320 and the coaming plate that the two links together, door-plate 310 and back Plate 320 is oppositely arranged, and 100 inner space of machine case body is divided into the first accommodating chamber 110 and second and accommodated by backboard 320 and coaming plate Chamber 120；Gas outlet 321 is located on backboard 320.

Please continue to refer to Fig. 3, door-plate 310 is connected on machine case body 100.

Wherein, door-plate 310 can be mounted on machine case body 100 by screw.

In the embodiment, sealing structure is equipped between door-plate 310 and machine case body 100, to further prevent dust, rainwater Deng enter the second accommodating chamber 120, the dust-proof and waterproof requirement of further satisfaction electrical cabinet assembly 300.

Wherein, sealing structure includes the sealing joint strip being located between door-plate 310 and machine case body 100 or sealing sponge 400.

In the embodiment, in order to improve dust-proof effect, sealing sponge 400 is selected.

Wherein, the sealing sponge 400 for the closed circular structure that is square is selected.

Specifically, the EVA sponge with a thickness of 1mm can be selected, and be connected to door-plate 310 and cabinet by way of stickup Between ontology 100.

On the basis of the above embodiments, the second accommodating chamber 120 also has the air inlet 311 being in communication with the outside.The ventilation When machine system works, extraneous gas enters the second accommodating chamber 120 by air inlet 311, and is flowed out by gas outlet 321, Cross-ventilation can be formed during this, so that the heat in the second accommodating chamber 120 be taken away, plays the role of heat exchange well.

As shown in Figure 3 and Figure 4, electrical cabinet assembly 300 further includes being located at the intracorporal heating element 500 of cabinet, and generate heat first device Between air inlet 311 and gas outlet 321, ambient atmos are entered part 500 by air inlet 311, and after heating element 500 The first accommodating chamber 110 is flowed into from gas outlet 321, and is discharged by centrifugal blower 200.

Specifically, heating element 500 includes frequency converter.

Wherein, frequency converter is located in above-mentioned cabinet body.

In the embodiment, after extraneous gas enters the second accommodating chamber 120 by air inlet 311, first device that generates heat is being flowed through When part 500, heat caused by heating element 500 can be taken away well, made 500 fast cooling of heating element, prevented It causes high temperature protection to be even damaged because temperature is excessively high.

As shown in figure 3, air inlet 311 is located on door-plate 310.

Please continue to refer to Fig. 3, in the embodiment, height where air inlet 311 is less than height where gas outlet 321, it may be assumed that will Air inlet 311 is arranged in 310 upper position of door-plate, and gas outlet 321 is located at 320 upper position of backboard.According to aerodynamic characteristics, The largely or entirely heat in the second accommodating chamber 120 can be discharged in time for the characteristics of being risen using hot-air, and heat It is more preferable that effect is discharged.

In the embodiment, the setting form of air inlet 311 can there are many, it is introduced below several, but be not limited to following Specific constructive form.

Such as: air inlet 311 uses shutter air inlet.

Specifically, shutter air inlet includes three (being not limited to three) openings that Open Side Down；Open Side Down for this Shutter air inlet can play the role of preventing dust, rainwater from entering the second accommodating chamber 120.

For another example: air inlet 311 includes one or more round tube holes.

It is equipped with please continue to refer to Fig. 3, at air inlet 311 for filtering the first filter 600 for entering gas by this mouthful；Or Person is equipped at gas outlet 321 for filtering the second filter 700 for sending out gas by this mouthful；Again either, air inlet 311 Place is equipped with for filtering the first filter 600 for entering gas by this mouthful and gas outlet 321 equipped with for filtering by the mouth Send out the second filter 700 of gas.

Wherein, which can play the role of filtering dust and other impurity, reduce in gas The influence of dust and other impurity to electric component in electrical cabinet assembly 300, so that the electrical cabinet assembly 300 be made to can satisfy Dust-proof requirement.

Second filter 700 can play the role of further filtering dust and other impurity, reduce in gas The influence to components in centrifugal blower 200 of dust and other impurity, so that it is dust-proof to can satisfy the VENTILATING SYSTEM BY VOLTAGE STEP Requirement.

In the embodiment, the structure type of first filter 600 and the second filter 700 can there are many.

Such as: both of which uses filter screen structure.

For another example: first filter 600 includes the first filter chamber, wherein the air inlet region of the first filter chamber and air inlet 311 It is connected, the outlet air region of the first filter chamber is connected with the second accommodating chamber 120；It, can be in gas in this kind setting Dust and other impurity play filtration well, to ensure that the gas entered in the second accommodating chamber 120 passes fully through the The filtering of one filter 600 reduces and dust or other impurity has even been avoided to enter in the second accommodating chamber 120.

Wherein, the second filter 700 includes the second filter chamber, the air inlet region of the second filter chamber and the second accommodating chamber 120 Connection, the outlet air region of the second filter chamber is connected with gas outlet 321；This kind setting in, can to the dust in gas with And other impurity play filtration well, to ensure the gas entered in the first accommodating chamber 110 completely through the second filter 700 filterings reduce and dust or other impurity have even been avoided to enter in the first accommodating chamber 110.

In the embodiment, the air inlet region of first filter 600 can cover air inlet 311；Either, the second filter 700 outlet air region can cover gas outlet 321；Again either, the air inlet region of first filter 600 can cover air inlet 311 and second the outlet air region of filter 700 can cover gas outlet 321.

Since the air inlet region of first filter 600 can cover air inlet 311, it is thus possible to guarantee by air inlet 311 The gas of entrance all passes through air inlet region and enters in first filter 600, further increases filter effect.

Since the outlet air region of the second filter 700 can cover gas outlet 321, it is thus possible to guarantee by gas outlet 321 The gas of entrance all passes through outlet air region and enters in the second filter 700, further increases filter effect.

Please continue to refer to Fig. 3, first filter 600 and the second filter 700 are respectively positioned in the second accommodating chamber 120.

On the basis of the above embodiments, first filter mounting rack and the second filtering are additionally provided in the second accommodating chamber 120 Device mounting rack.

Wherein, first filter mounting rack is bonded in the back that door-plate 310 is equipped with air inlet 311 by 3M glue and silicone adhesive Face；Second filter mounting rack is bonded on coaming plate or backboard 320 by 3M glue and silicone adhesive.
