A waterproof and dustproof case

Abstract

The invention discloses a waterproof and dustproof case used for accommodating an electric device. The case comprises a case housing, top cover plate assemblies, a dustproof assembly, panel assemblies and a waterproof joint. The top cover plate assemblies are arranged on a top plate of the case housing. The dustproof assemblies are arranged in openings in left and right sides of a main body plate. An inner cavity in one side where the dustproof assemblies are arranged is separated into a wind inlet channel and a wind outlet channel via a separator plate. The panel assemblies are arranged on the front face. The waterproof joint is arranged on a base plate. An electric device is embedded in an opening whose profile shape matches that of the electric device, and the opening is arranged in a middle separator plate. The interior of the case is in a quite closely sealed state, and the waterproof joint and the dustproof assemblies have better waterproof and dustproof effects, so waterproof and dustproof effects of the case are improved. The interior of the case housing is separated into the wind inlet channel and the wind outlet channel at an air channel, so a circulation heat dissipation air channel is formed and whole heat dissipation performance of the case is improved, thereby improving performance of the electric device and extending service lifetime of the electric device.

Description

technical field [0001] The invention relates to a cabinet, in particular to a waterproof and dustproof cabinet. Background technique [0002] During the use of the electrical device, in order to protect the safety and reliability of its working state, it is often necessary to place the electrical device in a protective case. For general electrical devices, such as low-power inverter models, the industry's conventional design of the chassis needs to meet the IP20 protection level. At the same time, the industrial design of the chassis needs to meet the IP54 protection level, so that the chassis can achieve strong waterproof and dustproof effects in special environments, and ensure the normal operation and service life of electrical devices. [0003] In order to achieve the purpose of the above-mentioned waterproof and dustproof chassis, in the design of the chassis of the existing electrical equipment, a sealing groove and silica gel are often arranged between the chassis bo...

AI Technical Summary

Problems solved by technology

[0004] In the process of applying the above-mentioned case, although there are louvers 02 with downward openings processed on both sides of the case body 01, the air outlet 03 with an open structure is used on the top, and the air intake and cooling holes 04 are directly processed on the bottom, and there is no structural modification to the inside of the case. Sealed, and there is no waterproof and dustproof structural design inside, so water droplets can easily enter the inside of the chassis from the upper, lower, left, and right side panels of the cabinet 01, which cannot achieve a good waterproof effect

At the same time, the dust-proof net provided on the inside of the louver 02, the air outlet 03 and the air inlet cooling hole 04 is pasted with adhesive. Once the adhesive is exposed to water or heated for a long time, the adhesiveness of the adhesive will weaken. As a result, the dust-proof net is easy to fall off, so that a better dust-proof effect cannot be achieved

[0005] In addition, in order to achieve a certain waterproof and dustproof effect in the existing chassis, the interior of the box body 01 does not isolate the air duct for the required heat dissipation electrical device, so that the electrical device 06 cannot form an independent air duct for heat dissipation after the electrical device 06 generates heat after power-on work , the heat dissipation performance of the chassis is greatly reduced
