Description

Technical Field

[0001] This utility model relates to the technical field of turbocharger compressor housing, specifically a turbocharger compressor housing. Background Technology

[0002] The compressor housing is one of the core components of a turbocharger. Its main function is to provide an air delivery passage for the compressor impeller and support its structure. It is a fixed component of the turbocharger and, together with the turbine housing and intermediate housing, constitutes the complete air passage system of the turbocharger.

[0003] Traditional turbocharger compressor housing outlet structures lack guiding structures, making it impossible to guide the exhaust airflow. This leads to a risk of surge at the compressor housing outlet during turbocharger operation. Therefore, there is an urgent need to design a turbocharger compressor housing to solve the above problems. Utility Model Content

[0006] The outer wall of the housing is integrally formed with a connecting flange on one side, and four through holes are opened on the outer wall of the connecting flange side.

[0007] The housing has a cavity, and a cooling component is bolted to one side of the outer wall of the housing.

[0008] The cooling component includes a housing, with a frame integrally formed on one side of the top outer wall of the housing, an installation groove on one side of the outer wall of the housing, and the installation groove communicating with the frame. A liquid storage area is provided inside the housing.

[0009] The cooler is bolted inside the frame, and multiple fins are welded to the outer wall of one side of the bottom of the cooler. The fins are located inside the liquid storage area.

[0010] The installation groove has a return pipe inserted into one side of its inner wall, with one end of the return pipe inserted into the cavity. The installation groove has a pump body installed on one side of its inner wall by bolts, and the pump body is connected to the storage area through a pipe. The pump body has a delivery pipe inserted into its outlet end, with one end of the delivery pipe extending into the cavity.

[0011] The frame shell is equipped with a cooling fan installed inside by bolts, and a dustproof net is installed on the top of the frame shell by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through its air outlet assembly, allows the integrated curved section and diverter block within the air outlet duct to guide multi-directional airflow during turbocharger operation, reducing turbulence losses and improving the uniformity of the compressor outlet airflow, thus avoiding the risk of surge caused by localized high pressure. Through its cooling assembly and cavity, the pump drives the coolant in the storage area to enter the cavity via a delivery pipe, directly cooling the high-temperature area of ​​the casing. The return pipe enables coolant recycling, significantly improving heat exchange efficiency compared to traditional air cooling. Furthermore, the cooler and fins are immersed in the storage area, actively reducing the coolant temperature and ensuring that the casing temperature does not drop under extreme operating conditions.

In this process, the integrally formed bend 11 and flow divider 10 inside the air outlet duct 9 can guide the airflow to multiple directions, reduce turbulence loss, improve the uniformity of the airflow inside the air outlet duct 9, and avoid the risk of surge caused by local high pressure. A connecting flange 6 integrally formed on one side of the outer wall of the housing 4, the connecting flange 6 facilitates the connection of the housing 4 and the turbocharger, and four through holes 7 are opened on one side of the outer wall of the connecting flange 6, the through holes 7 facilitate the bolts to pass through the connecting flange 6.

[0021] The shell 4 has a cavity 8. A cooling component 3 is bolted to one side of the outer wall of the shell 4. The cooling component 3 includes a housing 12. A frame 13 is integrally formed on one side of the top outer wall of the housing 12. A mounting groove 16 is formed on one side of the outer wall of the housing 12, and the mounting groove 16 is interconnected with the frame 13. A liquid storage area 22 is formed inside the housing 12, which stores coolant. A cooler 19 is bolted to the inside of the frame 13. The cooler 19 is preferably a TES1-00703 model. Multiple fins 20 are welded to one side of the outer wall of the bottom of the cooler 19. When the cooler 19 is started, it will cool the coolant in the liquid storage area 22 through the fins 20 to ensure that the shell 4 temperature does not drop under extreme conditions. The fins 20 are located inside the liquid storage area 22. A return pipe 21 is inserted into one side of the inner wall of the mounting groove 16, and one end of the return pipe 21 is inserted into the cavity 8. A pump body 17 is bolted to the side. The preferred model of the pump body 17 is DYH-22W. The pump body 17 is connected to the liquid storage area 22 through a pipe. A liquid delivery pipe 18 is inserted into the water outlet of the pump body 17. When the pump body 17 is started, it will input the coolant inside the liquid storage area 22 into the cavity 8. As the pump body 17 is started, the coolant will continuously flow into the cavity 8.

A dustproof net 15 is bolted to the top of the frame shell 13 to prevent dust from entering the inside of the frame shell 13.

[0022] Working principle: When the turbocharger is running, air flows into the housing 4 from the intake pipe 5, and then the air inside the housing 4 is discharged from the exhaust assembly 2. During this process, the one-piece molded bend 11 and the flow divider 10 in the exhaust duct 9 can guide the airflow to flow in multiple directions, reduce turbulence loss, improve the uniformity of airflow inside the exhaust duct 9, and avoid the risk of surge caused by local high pressure. At the same time, the pump body 17 drives the coolant in the liquid storage area 22 to enter the cavity 8 through the liquid delivery pipe 18, directly cooling the high temperature area of ​​the housing 4. The return pipe 21 realizes the recycling of coolant, and the heat exchange efficiency is greatly improved compared with traditional air cooling. In addition, the cooler 19 and fins 20 are immersed in the liquid storage area 22, and the coolant temperature is reduced through active cooling to ensure that the housing 4 temperature does not drop under extreme conditions.
