Description

Technical Field

[0001] This utility model relates to the field of turbocharger equipment technology, and in particular to a heat-insulated turbocharger housing. Background Technology

[0002] A turbocharger is a device that uses the exhaust energy of an engine to drive a turbine impeller, which in turn drives a compressor impeller to compress the intake air. Its housing typically consists of a turbine housing, a compressor housing, and an intermediate housing. The turbine housing directly withstands the impact of the high-temperature exhaust gas, and its operating temperature can reach over 700 ℃, and even exceed 950 ℃ in some gasoline engine applications.

[0003] In existing technologies, turbine housings are typically integrally cast from high-temperature heat-resistant cast iron or nickel-based alloys, and external heat shields or insulation layers are used to reduce heat transfer. However, the following problems still exist in practical applications:

[0004] Traditional turbine housing external insulation measures are mostly independent components that only provide protection and insulation functions, without providing insulation and support for the bottom of the overall equipment. This results in low flexibility of equipment use, requires a lot of auxiliary equipment for installation, increases the overall installation and use costs, and makes it difficult to disassemble the equipment when maintenance is needed, which also affects maintenance efficiency and causes many inconveniences.

[0005] Therefore, this utility model provides a heat-insulated turbocharger housing. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a heat-insulated turbocharger housing.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a heat-insulated turbocharger housing, including a turbocharger,

The top of the support column, located on the side of the fixing rod furthest from the fixing block, is threaded with a third positioning bolt extending into the heat insulation plate, reinforcing the connection between the support column and the heat insulation plate. The two fixing blocks on the same side are threaded with second positioning bolts, limiting the movement of the two fixing blocks on the same side. This multi-bolt structure facilitates quick assembly and disassembly of various components inside the bottom support housing, accelerating daily maintenance efficiency.
