Description

Supercharger volute with heat insulation structure

Technical Field

The utility model belongs to the technical field of superchargers, and particularly relates to a supercharger volute with a heat insulation structure.

Background

The automobile turbocharger mainly uses the inertial impulsive force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, the turbine drives the coaxial impeller, and the impeller presses the air sent by the air filter pipeline to make the air enter the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, the impeller compresses more air into the cylinder, and when the air pressure and density of the air increase, the combustion efficiency can be increased.

However, the temperature of the exhaust gas discharged from the engine is high, and heat is released when high-pressure compressed gas is utilized, so that the temperature of the supercharger is extremely high during operation, combustion is easily caused when substances such as oil stains are splashed on the surface of the supercharger, and meanwhile, the normal operation of surrounding equipment is influenced by strong heat radiation.

The existing volute heat shield structure is mostly used for realizing heat insulation by reducing the contact area, and the metal plate is bent, and the bent part is spliced with the edge of the shell of the supercharger so as to reduce the contact area. However, the fixing mode of single-side fixing has lower structural strength, resonance can be generated when the supercharger runs, metal fatigue is easily generated to cause shell rupture, and the safety of equipment is influenced.

Therefore, in order to solve the problems existing in the existing heat insulation structure of the supercharger, a supercharger volute with the heat insulation structure is provided.
