Abstract

The invention relates to an inter-cooling integral volute. An inter-cooling front air channel (1) and an inter-cooling rear air channel (2) are arranged in the volute (11); an annular intercooler (3) is arranged between the inter-cooling front air channel (1) and the inter-cooling rear air channel (2), is fixed in a shell (11) through a diffusion plate (4) and a rear disk (10) and is sealed with the volute (11) through a silicon seal (9); the volute (11) is provided with an air flow inlet (5), an air flow outlet (6), a cooling water inlet (7) and a cooling water outlet (8); and the cooling water inlet (7) and the cooling water outlet (8) are arranged on the same line and towards opposite directions, and are communicated with the annular intercooler (3). The inter-cooling integral volute absorbs heat transmitted by compressed fresh air through the annular intercooler, reduces the temperature of the compressed air and improves engine power.

Description

In cold integrated spiral case
Technical field
The invention belongs to field of turbochargers, be specifically related to a kind of in cold integrated spiral case.
Background technique
Motor has improved charge density through after the supercharging, and then increases engine power, improves engine consumption.But along with pressure ratio increases, the air temperature of blower outlet also increases, and has limited the raising of charge density to a certain extent, so has often increased intercooler after the supercharging and need in the air inlet cold.Experience shows, under given boost pressure, and 10 ℃ of the every declines of charge-air temperature, its density increases 3% approximately, and when the air oil consumption rate all remained unchanged, the power of diesel engine also can improve 3%.Along with the increase of engine power density, this effect can be more obvious.For the effect that increases cooling need increase the volume of intercooler, but the excessive intercooler of volume is unallowable to vehicular engine, even some vehicular engine is because the restriction in space can't be installed intercooler.The main effect of conventional supercharger air compressor spiral case is to collect compressed fresh air, is delivered to the suction tude of intercooler or motor then.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned deficiency, provide a kind of in cold integrated spiral case, this spiral case absorbs the heat that the compression fresh air transmits by annular intercooler, reduces compressed-air actuated temperature, has promoted engine power.
Technological scheme of the present invention: cold integrated spiral case in a kind of, cold preceding air-flow path during it comprises, in cold back air-flow path, the annular intercooler, the diffusion plate, airflow inlet, flow outlet, cooling water intake, cooling water outlet, O-ring seal, back of the body dish and spiral case, cold preceding air-flow path in being provided with in the spiral case, in cold back air-flow path, in cold before air-flow path with in be provided with annular intercooler between the cold air-flow path afterwards, the annular intercooler is by the diffusion plate, back of the body dish is fixed in the housing, seal by O-ring seal between annular intercooler and the spiral case, spiral case is provided with airflow inlet, flow outlet, cooling water intake, cooling water outlet, cooling water intake, cooling water outlet is 180 ° of layouts, cooling water intake, cooling water outlet is communicated with annular intercooler.
The bore of described cooling water intake, cooling water outlet is 8～100mm.Axial distance L 〉=the 10mm of described annular intercooler, inner diameter d 〉=40mm, outer diameter D 〉=50mm.
The present invention compared with prior art has following beneficial effect: the present invention has increased annular intercooler between air-flow path and the cooling back air-flow path before cooling, absorb the heat that the compression fresh air transmits by annular intercooler, reduce compressed-air actuated temperature.It is simple in structure, in cold integrated spiral case not only possess the effect of conventional compressor volute, can also bear the effect that intercooler reduces the pressurization gas temperature, effectively promoted engine power, improve heat load and delivery temperature, reduced the physical dimension of motor.
