Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of noise reduction devices, and more specifically, to a turbocharger noise reduction device. Background Art
[0002] As an important part of modern engine technology, turbochargers use the energy of engine exhaust gas to compress air, thereby significantly increasing the engine's air intake, thereby increasing engine power, improving economy and reducing emissions. However, with the widespread application of turbochargers in cars, racing cars, trucks, agricultural machinery, ships and other fields, the accompanying noise problem has become increasingly prominent. Therefore, it is particularly important to develop a noise reduction device that can effectively reduce turbocharger noise.
[0003] Traditional turbocharger designs often focus on improving power and efficiency, while solutions to noise problems are relatively limited. These noises are mainly composed of two parts: aerodynamic noise and structural vibration noise. Aerodynamic noise originates from the complex flow of gas in the turbocharger, while structural vibration noise is the radiation noise generated by the vibration of the volute caused by the high-speed rotation of the impeller. Utility Model Content
[0004] In order to overcome the above defects of the prior art, the utility model provides a turbocharger noise reduction device to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a supercharger noise reduction device, comprising a base plate, a shell fixedly connected to the top of the base plate, a sound insulation component fixedly connected to the inside of the shell, a ventilation pipe connected to the top of the shell, the ventilation pipe passing through the sound insulation component, a silencer component fixedly connected to the top of the shell, and an exhaust pipe connected to the top of the silencer component.
[0006] As a further description of the above technical solution:
[0007] The silencer assembly comprises a tube body fixedly connected to the shell, a first silencer tube is arranged inside the tube body, and one end of the first silencer tube is fixedly connected to the ventilation tube.
[0008] As a further description of the above technical solution:
[0009] The other end of the first silencer pipe is fixedly connected to a first isolation plate, a through hole is opened at the center of the first isolation plate, and the top of the first isolation plate is connected to a second silencer pipe.
[0010] As a further description of the above technical solution:
[0011] One end of the second silencer pipe is fixedly connected to a second isolation plate, and the second isolation plate is fixedly connected to the pipe body.
[0012] As a further description of the above technical solution:
[0013] The sound insulation component includes a sound insulation felt fixedly connected to the inside of the shell, sound insulation cotton fixedly connected to the inside of the sound insulation felt, and a protrusion fixedly connected to the inner wall of the sound insulation cotton.

[0016] As a further description of the above technical solution:
[0017] The bottom of the muffler plate is fixedly connected to the base plate, and a plurality of honeycomb holes are provided on the surface of the muffler plate.
[0018] Technical effects and advantages of the utility model:
[0019] 1. By setting a sound insulation component, when in use, the utility model is fixed at the center of the outer end of the turbocharger. When the turbocharger is started, the noise generated by the impeller is divided into multiple silencer chambers by the sound insulation felt, sound insulation cotton, sound insulation board and silencer board. Therefore, when the generated noise passes through the sound insulation component, the noise can be lost to a certain extent, achieving a better noise reduction effect.

By setting up a silencer assembly, the noise that is not eliminated can reach the silencer chamber between the first isolation plate and the second isolation plate through the first silencer tube in the tube body for loss, and then be silenced through the through hole and the second silencer tube. Finally, the gas is discharged through the exhaust pipe, thereby achieving a better silencer effect. BRIEF DESCRIPTION OF THE DRAWINGS
