Description
Technical field
The utility model belongs to turbosupercharger of car engine field, specifically a kind of with self cooling turbocharger middle body.
Background technique
In recent years, along with engine turbine supercharging technology is fast-developing, turbosupercharger is popularized gradually in automobile industry.Increasing motor, by configuration turbosupercharger, reaches the demand improving power performance, reduce oil consumption, reduce exhaust emissions.
The special operation condition of motor car engine height rotating speed, high-temperature, proposes more harsh requirement to the cooling of pressurized machine.The cooling of turbosupercharger is a serious problem, and high temperature can cause floating bearing to lose efficacy, sealing position seriously causes seal ring to lose elasticity because of carbon deposit.But more serious situation is when stopping suddenly under appearing at high engine speeds, high load operating mode, now produce " heat flows backwards " phenomenon: because turbine case and turbine wheel are still located at high operating temperatures, during engine sudden parking, lubricant oil supply also stops suddenly, cooling system also quits work, heat flows back to bearing portion and sealing position from turbine case and turbine wheel, and this two places temperature is raised suddenly.At present, turbosupercharger adopts bearing body structure, improves cooling efficiency, to improve the reliability of bearing by increasing the mode such as oil cooling, water-cooled pipeline in intermediate inside.
Summary of the invention
To be solved in the utility model be turbosupercharger intermediate heat radiation problem, provide a kind of with self cooling turbocharger middle body.
The utility model have employed following technological scheme:
With self cooling turbocharger middle body, it comprises intermediate, thermal shield and bearing, described intermediate comprises intermediate ectosome and intermediate endosome, insulated cavity is formed between intermediate ectosome and intermediate endosome, one end side face of intermediate ectosome is provided with radiating fin, and the end face of the other end of intermediate ectosome is fixed wtih thermal shield.
Described radiating fin is provided with two panels, and this two panels radiating fin circumferential hoop is around being integrally fixed on intermediate ectosome.
Described insulated cavity is around being located between intermediate ectosome and intermediate endosome, and its cross section is triangle.
Described bearing is semifloating bearing.
The utility model has the advantages that the area of contact that can reduce turbine case and intermediate, reduce turbine case and conduct heat to intermediate, can increasing heat radiation area, accelerate the cooling of pressurized machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation installing semifloating bearing.
Embodiment
As Fig. 1, shown in Fig. 2, with self cooling turbocharger middle body, it comprises intermediate 1, thermal shield 4 and bearing 5, described intermediate comprises intermediate ectosome 1a and intermediate endosome 1b, insulated cavity 2 is formed between intermediate ectosome 1a and intermediate endosome 1b, one end side face of intermediate ectosome 1a is provided with radiating fin 3, the end face of the other end of intermediate ectosome 1a is fixed wtih thermal shield 4, insulated cavity design is between the turbine end and thermal shield 4 of intermediate 1, on the one hand can weight reduction, the area of contact of turbine case and intermediate can be reduced on the other hand, reduce turbine case to conduct heat to intermediate, the radiating fin of intermediate both sides can increasing heat radiation area, accelerate the cooling of pressurized machine.
Generally, radiating fin 3 is provided with two panels, this two panels radiating fin circumferential hoop is on the outer circumferential face being integrally fixed on intermediate ectosome 1a, radiating fin can increase the heat diffusion area of intermediate, after absorbing the heat on intermediate, contact with air, accelerate the cooling of pressurized machine, improve cooling efficiency.
Insulated cavity 2 is around being located between intermediate ectosome 1a and intermediate endosome 1b, and its cross section is triangle, and wherein, bearing is semifloating bearing 5, and intermediate adopts the overall structure of semifloating bearing, and mechanical efficiency is improved; Greatly shorten the length of pressurized machine simultaneously, reduce part, be convenient to assembling.When not changing former machine cooling structure, can effectively reducing the temperature of intermediate, improving the efficiency of turbosupercharger.
