Description

Technical Field

[0001] The invention relates to the technical field of silent covers, in particular to a silent cover for a diesel generator set. Background Art

[0002] A silent cover is a covering designed to reduce the noise generated by a device when it is running. It is commonly used on devices such as computer cases, printers, and air conditioners. The silent cover absorbs and isolates noise through sound insulation materials and structural design, thereby reducing the impact of the device on the surrounding environment when it is running. When choosing a silent cover, you should consider the sound insulation effect of the material, the heat dissipation performance, and whether it is easy to install and maintain.

[0003] According to the authorization announcement number CN 212615033 U, the disclosed "a silent cover structure for a diesel generator set" includes a cover body, a cover door and an exhaust channel. The cover body is provided with a cover door on the top, and an exhaust channel is fixedly provided on the side of the cover body. The inner surfaces of the cover body and the cover door are provided with sound insulation cotton. The left and right ends of the inner wall of the cover body are provided with sliding grooves, and the sliding grooves are connected by a supporting plate for sliding; that is, the sound insulation cotton inside the cover body uses its own sound insulation and sound absorption function to reduce the operating noise of the internal structure of the generator set body. Although the sound insulation cotton can absorb part of the sound, its sound insulation effect is limited because it mainly targets the absorption of medium and high frequency sounds. The sound insulation cavity uses a spatial structure, a combination of air layers and materials to block and absorb sound, thereby achieving a better sound insulation effect.

[0004] The existing silent cover usually uses sound insulation cotton as the sound insulation material of the diesel generator set, which is mainly aimed at absorbing medium and high frequency sounds, while low frequency sounds can still penetrate the entire silent cover, thus affecting the sound insulation effect; at the same time, the existing sound insulation cover covers the diesel generator set, making it difficult for the heat generated by the diesel generator set to dissipate, affecting the heat dissipation effect of the diesel generator set. To this end, we provide a silent cover for diesel generator sets. Summary of the invention
