Abstract
The invention relates to an inter-cooling integrated volute. A volute body (5) is formed by pressure casting through a metal die. A before-inter-cooling airflow channel (3) and an after-inter-cooling airflow channel (7) are arranged in the volute body (5), an annular intercooler (6) is arranged between the before-inter-cooling airflow channel (3) and the after-inter-cooling airflow channel (7), fins (14) used for enhancing heat transfer are arranged in the annular intercooler (6), an included angle is formed between the pointing direction of the fins (14) and the tangent direction, and the pointing direction of the fins (14) is consistent with the airflow direction. An airflow inlet (1), an airflow outlet (8), a cooling water inlet (9) and a cooling water outlet (10) are formed in the volute body (5). The cooling water inlet (9) and the cooling water outlet (10) are distributed in the circumferential direction by 180 degrees. The inter-cooling integrated volute lowers the temperature of compressed air, and improves power of an engine. While the power of the engine is improved and thermal load and discharge temperature are improved, the structural size of the engine is reduced.
Description
Technical field
The present invention relates to turbo-charger technical field, be specifically related to cold integrated spiral case in one.
Background technique
Motor improves charge density after supercharging, and then increases engine power, improves engine consumption.But along with pressure ratio increases, the air temperature of blower outlet also increases, and limits the raising of charge density to a certain extent, therefore often adds intercooler after supercharging and cools engine charge.Experience shows, under given boost pressure, charge-air temperature often declines 10 DEG C, and its density about increases 3%, and when air oil consumption rate all remains unchanged, the power of diesel engine also can improve 3%.Along with the increase of engine power density, this effect can be more obvious.In order to the effect increasing cooling needs to increase the volume of intercooler, but the excessive intercooler of volume is unallowable concerning vehicular engine, and even some vehicular engine is due to the restriction in space, cannot install intercooler.
Summary of the invention
Cold integrated spiral case in one, it comprises airflow inlet 1, impeller 2, Diffuser 3, back of the body dish 4, compressor volute 5, annular intercooler 6, air-flow path 7, flow outlet 8, water intake 9, water outlet 10, O-ring seal 11, O-ring seal 12, O-ring seal 13, after impeller 2 is arranged on the airflow inlet 1 of compressor volute 5, annular intercooler 6 is arranged in the air-flow path 7 of annular, compressor volute 5, cavity between back of the body dish 4 and annular intercooler 6 is Diffuser 3, water intake 9 is arranged on the bottom of compressor volute 5, water outlet 10 is arranged on compressor volute 5 top.
Fin 14 in described annular intercooler 6 is 20-60 degree with tangential direction angle.
Described annular intercooler 6 is fixed by the inner concave station of compressor volute 5 and back of the body dish 4.
In described, cold integrated spiral case is provided with the water intake 9 of at least one cooling water and the water outlet 10 of a cooling water, and water intake 9 distributes in 180 ° of circumferences with water outlet 10.
Described compressor volute 5 adopts metal pattern high pressure die casting shaping.
Described annular intercooler 6 axial dimension L is at least 0.08 times of impeller 2 outlet diameter, and the ratio of annular intercooler 6 internal diameter d1 and impeller 2 outlet diameter is at least 1.2, and annular intercooler 6 outside diameter d 2 is 1.5 ~ 3 with the ratio of impeller 2 outlet diameter.
Beneficial effect of the present invention:
The present invention adopts between Diffuser 3 and air-flow path 7, adds annular intercooler 6, and the heat that after absorbing compression by annular intercooler 6, fresh air transmits, reduces compressed-air actuated temperature.Invention structure is simple, not only possesses the effect of conventional compressor volute, can also bear the effect that intercooler reduces pressurization gas temperature, while engine power lifting and heat load and delivery temperature improvement, decreases the physical dimension of motor.
Accompanying drawing explanation
The structural representation of Fig. 1 cold integrated spiral case in being;
The structural profile schematic diagram of Fig. 2 cold integrated spiral case in being;
Fig. 3 is the structural profile schematic diagram of annular intercooler;
Fig. 4 is annular intercooler water inlet and outlet direction schematic diagram.
Embodiment
Fresh air enters compressor volute 5 by airflow inlet 1, after impeller 2 does work compression, pressure and temp raises and enters cold front air-flow path 3 diffusion reduction of speed in Diffuser, after cold in entering after annular intercooler 6 cools, air-flow path 7 is collected by it again, transports to engine air inlet tube or other use device of air eventually through flow outlet 8.Cycle of engine cooling water enters annular intercooler 6 by water intake 9, absorb the high temperature gas flow heat that annular intercooler 6 transmits, and reduces compressed-air actuated temperature, then flowed out by cooling water outlet 10.
