Description
Technical field
The present invention relates to turbo-charger technical field, be specifically related to cold integration spiral case in one.
Background technology
Engine improves charge density after supercharging, and then increases engine power, improves engine consumption.But with
Pressure ratio to increase, the air themperature of blower outlet also increases, and limits the raising of charge density to a certain extent,
Therefore often add charge air cooler after supercharging engine charge is cooled down.Experience have shown that, under given boost pressure, increase
Pressure air themperature often declines 10 DEG C, and its density about increases 3%, when air oil consumption rate all keeps constant, and the merit of diesel engine
Rate also can improve 3%.Along with the increase of engine power density, this effect can become apparent from.In order to increase the effect needs of cooling
Increase the volume of charge air cooler, but the excessive charge air cooler of volume is unallowable for vehicular engine, even some car
With engine due to the restriction in space, it is impossible to install charge air cooler.
Summary of the invention
In one cold integration spiral case, it include airflow inlet 1, impeller 2, diffuser 3, back of the body dish 4, compressor volute 5,
Annular charge air cooler 6, gas channel 7, air stream outlet 8, water inlet 9, delivery port 10, O-ring seal 11, O-ring seal 12, fluid sealant
Circle 13, after impeller 2 is arranged on the airflow inlet 1 of compressor volute 5, annular charge air cooler 6 is arranged in the gas channel 7 of annular,
Compressor volute 5, the cavity between back of the body dish 4 and annular charge air cooler 6 is diffuser 3, and water inlet 9 is arranged on compressor volute 5
Bottom, delivery port 10 is arranged on compressor volute 5 top.
Fin 14 in described annular charge air cooler 6 is 20-60 degree with tangential direction angle.
Described annular charge air cooler 6 is fixed with back of the body dish 4 by the internal concave station of compressor volute 5.
In described, cold integration spiral case is provided with water inlet 9 and the delivery port of a cooling water of at least one cooling water
10, and water inlet 9 is circumferentially distributed in 180 ° with delivery port 10.
Described compressor volute 5 uses metal pattern compression casting to be molded.
Described annular charge air cooler 6 axial dimension L is at least 0.08 times of impeller 2 outlet diameter, annular charge air cooler 6 internal diameter
D1 is at least 1.2 with the ratio of impeller 2 outlet diameter, and annular charge air cooler 6 outside diameter d 2 is 1.5 with the ratio of impeller 2 outlet diameter
~3。
Beneficial effects of the present invention:
The present invention uses and adds annular charge air cooler 6 between diffuser 3 and gas channel 7, by annular charge air cooler 6
The heat that after absorbing compression, fresh air transmits, reduces compressed-air actuated temperature.Inventive structure is simple, not only possesses routine and calms the anger
The effect of machine spiral case, it is also possible to bear charge air cooler and reduce the effect of pressurization gas temperature, promotes and heat in engine power
While load and delivery temperature are improved, decrease the physical dimension of engine.

Detailed description of the invention
Fresh air enters compressor volute 5 by airflow inlet 1, and after impeller 2 acting compression, pressure and temp raises
Enter cold front gas channel 3 diffusion reduction of speed in diffuser, colder in entering after annular charge air cooler 6 cooling after gas channel 7
Collected by it, transport to engine air inlet tube eventually through air stream outlet 8 or other use device of air.Cycle of engine cooling water is by entering
The mouth of a river 9 enters annular charge air cooler 6, absorbs the high temperature gas flow heat of annular charge air cooler 6 transmission, reduces compressed-air actuated temperature, then
Flowed out by cooling water outlet 10.
