Modular box-type assembly-structure low-noise cabinet

Abstract

The invention discloses a modular box-type assembly-structure low-noise cabinet. The cabinet comprises a chassis, an electric control cabinet, a host cabinet, a main silencing cabinet and a filteringcabinet, wherein the electric control cabinet, the host cabinet, the main silencing cabinet and the filtering cabinet are sequentially arranged on the chassis from left to right. The host cabinet is of a rectangular structure and comprises a host cabinet body, a main top cabinet and a main bottom cabinet, the main top cabinet and the main bottom cabinet are fixed at the upper end and the lower endof the host cabinet body respectively, and an inner cavity of the host cabinet body correspondingly communicates with an inner cavity of the main top cabinet and an inner cavity of the main bottom cabinet. Sound insulation board units are arranged in the directions of the six side faces of the host cabinet body respectively, and each sound insulation board unit comprises an inner layer sound insulation board and an outer layer sound insulation board. The front and back surfaces of each inner layer sound insulation board are each provided with silencing cotton, and silencing cotton is attachedto the inner side of each outer layer sound insulation board. During assembly, the working space is easy to arrange, the operation is convenient, warping deformation is not likely to happen, the structural strength is good, and the sealing surface can be easily ensured to be flat. Noise of a host needs to penetrate through three layers of sound insulation cotton when spreading in any direction, so that the sound insulation effect is good.

Description

Technical field: [0001] The invention relates to a low-noise cabinet with a modular box-type assembled structure. Background technique: [0002] Fan cabinets can usually be divided into two types: frame type and assembled type. [0003] The frame structure has good strength and the sealing of the cabinet is easy to achieve, but the pickling, painting and other processes in the manufacturing process require large-scale lifting and turning equipment, which is not available to most sheet metal companies; at the same time, the structure is fixed and the expandability is poor. [0004] The assembled structure is better in manufacturability, but the structural strength is slightly weaker, the cabinet is easily deformed, and the sealing of the cabinet is not easy to guarantee. [0005] Common assembled cabinets can be divided into plate structure and box structure. [0006] The plate structure is to build the cabinet directly on the chassis with plates of various shapes, so it is...

AI Technical Summary

Problems solved by technology

[0006] The plate structure is to build the cabinet directly on the chassis with plates of various shapes, so it is small in size, easy to manufacture, convenient to transport, and easy to arrange the assembly of internal parts; but the plates are easy to warp and deform, the number of parts is large, and the assembly is complicated. Many board connection positions, poor reliability, poor cabinet strength

[0007] The box-type structure uses multiple boxes placed side by side in series on a chassis to directly form a cabinet, so the number of parts is small, the assembly is fast, and the structural strength is good; but the parts are assembled inside a single box, and the internal parts of the box are installed. The work arrangement is cramped
