Abstract

The invention discloses a wave-resistant muffler. The muffler includes an inner pipe and an outer pipe installed on the inner pipe. One end of the outer pipe is provided with close-up blocks distributed at equal intervals, the close-up blocks are welded and fixed with the side wall of the inner pipe, the portion, near the outer pipe, of the side wall of the inner pipe is provided with cooling finsdistributed at equal intervals, the end, away from the close-up blocks, of the side wall of the outer pipe is provided with heat emission holes distributed annularly, the end, away from the close-upblocks, of the inner wall of the outer pipe is welded with contraction rings, the inner walls of the contraction rings are welded and fixed with the side wall of the inner pipe, the inside of the inner pipe is sleeved with a muffler assembly, the muffler assembly includes a muffler outer pipe and a muffler inner pipe sleeving the inside of the muffler outer pipe, and one end of the muffler inner pipe is welded with sealing rings. Through the combination of the cooling fins, heat dissipation is facilitated, shrinkage and deformation, caused by excessive temperature, of a resin sound absorptionlayer are avoided, the service life of the muffler is prolonged, the muffling area is increased, the muffling effect is increased, the better muffling effect is achieved, and installation is facilitated.

Description

technical field [0001] The invention relates to the technical field of mufflers, in particular to a wave resistive muffler. Background technique [0002] The muffler is divided into resistive muffler and resistive muffler according to the working principle. Since the muffler frequency band of the resistive muffler is narrow, it is mainly used for low-frequency muffler, and it has little effect on the middle and high frequency muffler. Therefore, the introduction of the resistive muffler can solve the problem. insurmountable problem. The advantage of the resistive muffler is that it can eliminate noise in a wide range of medium and high frequencies, especially for high-frequency sound waves. [0003] The existing wave-resistive muffler has a general sound-absorbing effect and low heat dissipation performance, so a wave-resistive muffler is now proposed. Contents of the invention [0004] The object of the present invention is to propose a wave resistive muffler in order t...
