TECHNICAL FIELD The present invention relates to the technical field of electromechanical equipment, and particularly to a distribution cabinet heat-dissipation exhaust device.
BACKGROUND Distribution cabinets, the final-stage equipment of distribution systems, are divided into power distribution cabinets, lighting distribution cabinets and metering cubicles. The distribution cabinet is a collective name for motor control centers. The motor control center is used in cases where the load is concentrated and many closed circuits are present. A distribution cabinet is typically provided with heat-dissipation holes in the housing and with a heat-dissipation fan on the inside for heat dissipation to spread out the heat in the distribution cabinet. However, the heat-dissipation assemblies in the existing distribution cabinets generate noise while running. Therefore, a distribution cabinet heat-dissipation exhaust device having a good noise reduction effect is provided herein.
SUMMARY The present invention mainly solves the technical problem of providing a distribution cabinet heat-dissipation exhaust device which can greatly reduce the noise generated by the exhaust fan during heat dissipation and thus the stability of the electric device running in the distribution cabinet can be effectively improved. In order to solve the above technical problem, the following technical scheme is adopted by the present invention: The present invention comprises a distribution cabinet body wherein a vent is formed in a bottom of the distribution cabinet body and connected to an air-inlet pipe, an inlet air noise-reduction structure is arranged in the air-inlet pipe, a fan-fixing frame is fixedly arranged on a bottom plate of the distribution cabinet body, an exhaust fan is detachably mounted in the fan-fixing frame,
. . LU502175 the exhaust fan and the vent are coaxially arranged, the exhaust fan blows air upward, and an exhaust noise-reduction structure is mounted on top of the fan-fixing frame; the exhaust noise-reduction structure comprises a mounting frame and guiding plates, a plurality of sets of the guiding pates are uniformly arranged at intervals in the length direction of the mounting frame, and the guiding pates are detachably connected with the mounting frame; a plurality of air-outlet regions are arranged on a side wall of the distribution cabinet body.
Further, the inlet air noise-reduction structure comprises a pipe body and a noise-reduction pipe, which are both hollow tubular structures; an outer side of the noise-reduction pipe is sleeved with the pipe body, splitter plates are circumferentially uniformly distributed between the pipe body and the noise-reduction pipe, and a spiral cavity wall is arranged in the noise-reduction pipe.
Further, each of the guiding plates is clamped on two sides with mounting bars, each of the mounting bars is provided with a positioning post on one side, and positioning recesses that match the positioning posts are formed in inner walls of the mounting frame.
Further, guiding holes are formed and uniformly distributed in the guiding plates.
Further, the air-outlet regions consist of a plurality of heat-dissipation holes.
Further, fixing posts that match mounting holes in the exhaust fan are arranged on top of the fan- fixing frame.
Beneficial effects of the present invention: When the exhaust fan is in operation, air enters through the air-inlet pipe arranged, and since the air-inlet pipe has the inlet air noise-reduction structure, the double-layer design can well insulate sound.
The guiding plates can not only guide air, but also effectively reduce the noise generated by airflow, likewise the spiral cavity wall, which can greatly reduce the noise generated by the air passing through the pipe.
In the exhaust noise-reduction structure, the guiding plates are detachably arranged in the mounting frame.
The obliquely arranged guiding plates enable effective guiding and buffering of
. _ ‘qe . . , . LU502175 air. In addition, the guiding holes uniformly arranged in the guiding plates can improve the uniformity of the outlet air, thereby reducing the noise generated by the airflow. Therefore, by using the design of the present invention, the noise generated by the exhaust fan during heat dissipation can be greatly reduced; further, as the guiding plates are detachably mounted, they can be regularly cleaned easily, thereby improving the stability of the electric device running in the distribution cabinet.
