Description

Technical Field

[0001] This utility model relates to the field of turbocharger technology, and in particular to a turbocharger housing with high noise reduction. Background Technology

[0002] A turbocharger is an air compressor that increases the intake air volume by compressing air. A turbocharger consists of a turbocharger housing, an impeller, and other auxiliary structures.

[0003] In existing turbochargers, the main noise during use is caused by the rotation of the impeller inside the housing. However, the noise reduction effect of the turbocharger housing itself is not good, which affects the working environment of the turbocharger. Therefore, in order to better realize the noise reduction function of the turbocharger housing, promote the technological progress of the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the turbocharger housing structure in the prior art. Utility Model Content

The protective assembly includes two protective shells that wrap around the outside of the turbocharger housing body. Multiple heat-conducting fins are fixedly connected to one inner wall of each protective shell. A sound-absorbing block is inserted between every two heat-conducting fins. A connecting block is fixedly connected to one outer wall of each protective shell. The connecting blocks of the two protective shells are fixed together by threads.

[0007] Furthermore, a first rubber pad is provided between the two connecting blocks.

[0008] Furthermore, a second rubber pad is fixedly connected to the top outer wall of the protective shell.

[0009] Furthermore, a third rubber pad is fixedly connected to the inner wall of the protective shell.

[0010] Furthermore, a connecting seat is fixedly connected to one side of the outer wall of the protective shell, and a heat dissipation component is provided at one end of the connecting seat.

A support frame is fixedly connected between the multiple inner walls of the connecting shell, and a cooling fan is fixedly connected to one side of the support frame.

[0012] Furthermore, dustproof nets are fixedly connected to both ends of the connecting shell.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The sound-absorbing blocks absorb the noise generated by the turbocharger during operation, thereby achieving a good noise reduction effect and improving the noise reduction effect of the turbocharger housing itself.

[0015] 2. A first rubber pad is placed between the connecting blocks of the two protective shells to provide a good buffering effect and prevent vibration transmission. Then, a second rubber pad is bonded to the top outer wall of the protective shell to further reduce the transmission of vibration and noise and improve the noise reduction effect.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 A high-noise-reduction turbocharger housing includes a turbocharger housing body 1. The outer surface of the turbocharger housing body 1 is provided with a protective component 2. The protective component 2 includes two protective shells 201. The two protective shells 201 wrap around the outside of the turbocharger housing body 1. The mating gap between the two protective shells 201 is ≤0.5mm. Multiple heat-conducting plates 202 are welded to the inner wall of one side of the protective shell 201. The heat-conducting plates 202 are copper plates with a thickness of 0.8mm, a spacing of 8mm, and a height of 2 / 3 of the inner cavity height of the protective shell 201.

[0025] A sound-absorbing block 203 is inserted between every two heat-conducting plates 202. The sound-absorbing block 203 is one of mineral wool block or glass fiber block. The density of the sound-absorbing block 203 is 80-120 kg / m³, the thickness is 10-15 mm, and the distance between the sound-absorbing block 203 and the heat-conducting plate 202 is 3-5 mm. The porosity of the sound-absorbing block 203 is 85%-92%, and the ratio of its length to the inner length of the protective shell 201 is 0.9:1.

[0026] The protective component 2 is wrapped around the outside by two protective shells 201, which can prevent external objects from damaging the turbocharger housing body 1, and can also embed multiple heat-conducting plates 202 and sound-absorbing blocks 203 inside to effectively reduce noise and help dissipate heat. One side of the outer wall of the protective shell 201 has an integrally formed connecting block 204, and the connecting blocks 204 of the two protective shells 201 are fixed together by threads.

[0027] A first rubber pad 205 is provided between the two connecting blocks 204. The first rubber pad 205 is provided between the connecting blocks 204 of the two protective shells 201 to provide a good buffering effect and prevent vibration transmission.

[0028] A second rubber pad 3 is bonded to the top outer wall of the protective shell 201 to further reduce the transmission of vibration and noise.

[0029] A third rubber pad 4 is bonded to the inner wall of the protective shell 201. The third rubber pad 4 is bonded to the inner wall of the protective shell 201 to reduce the vibration generated by the turbocharger when running at high speed.

[0030] The first rubber pad 205 is made of nitrile rubber with a Shore A hardness of 50-55 degrees and a thickness of 5±0.2mm; the second rubber pad 3 is made of silicone rubber with a Shore A hardness of 40-45 degrees; the third rubber pad 4 is made of neoprene rubber with a Shore A hardness of 60-65 degrees and a thickness of 3-4mm.

[0031] A connecting seat 5 is welded to one side of the outer wall of the protective shell 201. A heat dissipation component 6 is provided at one end of the connecting seat 5. The heat dissipation component 6 includes a connecting shell 601. The connecting shell 601 is fixed to one end of the connecting seat 5 by bolts. A support frame 602 is fixed between the multiple inner walls of the connecting shell 601 by bolts. A cooling fan 603 is fixed to one side of the support frame 602 by bolts. The cooling fan 603 has a rated power of 18W and an air volume of ≥15CFM.

[0032] The cooling fan 603 blows air toward the protective shell 201, thereby cooling the protective shell 201 and improving the cooling efficiency of the turbocharger. Both ends of the connecting shell 601 are fixed with dustproof mesh 604 by bolts. The dustproof mesh 604 is made of stainless steel with a mesh density of 200 meshes and a thickness of 0.3mm, thereby preventing dust from entering the connecting shell 601.

[0035] The working principle of this embodiment is as follows: When in use, firstly, the two protective shells 201 are wrapped around the outside of the turbocharger housing body 1, and then the bolts are passed through the two connecting blocks 204 to fix the two protective shells 201, thereby completing the assembly of the protective component 2.

[0036] Then, the heat from the turbocharger during operation is transferred to the protective shell 201 through the heat-conducting fins 202 made of copper sheets, and then dissipated into the air through the protective shell 201. At the same time, the cooling fan 603 blows air toward the protective shell 201, thereby cooling the protective shell 201 and improving the cooling efficiency of the turbocharger.

[0037] Next, the noise from the turbocharger during operation is absorbed by the sound-absorbing block 203, thus reducing noise. Then, the first rubber pad 205 is placed between the connecting block 204 of the two protective shells 201 to provide a good buffering effect and prevent vibration transmission. Next, the second rubber pad 3 is bonded to the top outer wall of the protective shell 201 to further reduce the transmission of vibration and noise. Then, the third rubber pad 4 is bonded to the inner wall of the protective shell 201 to reduce the vibration generated by the turbocharger during high-speed operation, thereby reducing the collision between the protective shell 201 and the turbocharger housing body 1, and thus better achieving the noise reduction effect.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
