Problems solved by technology

In order to increase the cooling effect, it is necessary to increase the volume of the intercooler, but an intercooler that is too large is not allowed for a vehicle engine, and even some vehicle engines cannot be installed with an intercooler due to space constraints.

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

technical field [0001] The invention belongs to the field of turbochargers, and in particular relates to an intercooling integrated volute. Background technique [0002] After the engine is supercharged, the air-fill density is increased, thereby increasing engine power and improving engine fuel consumption. However, as the boost ratio increases, the temperature of the air at the outlet of the compressor also increases, which limits the increase in the charge density to a certain extent. Therefore, after supercharging, an intercooler is often added to require intercooling of the intake air. Experience shows that at a given boost pressure, the density of the boost air increases by about 3% for every 10°C decrease in the temperature of the boost air. When the air fuel consumption rate remains unchanged, the power of the diesel engine can also increase by 3%. This effect becomes more pronounced as the engine power density increases. In order to increase the cooling effect, it...
