Problems solved by technology

The role of turbocharging is to increase the density of air entering the cylinder by increasing the intake pressure, thereby increasing the amount of air charged, so that more fuel can be supplied and greater power can be obtained. The temperature of the air after the intake is high. In order to improve the intake efficiency, the high-temperature gas needs to be cooled. In order to solve this problem, an intercooler is generally added between the supercharger and the intake manifold, and the high-temperature air is cooled by the intercooler. However, due to the size and position of the intercooler, it takes up a lot of space for the whole machine to be arranged on the vehicle, and it is inconvenient to install and disassemble.
Under the working conditions of the engine, there is a risk of overloading the intercooler water pipe near the flange side of the intercooler and the flange surface of the manifold, resulting in fatigue failure and a series of problems such as resonance noise.
Once the intercooler fails due to fatigue and leaks water into the engine combustion chamber, the engine will be directly damaged and scrapped. Therefore, the installation design of fixing the intercooler through the support ribs in the intake manifold is high risk. Therefore, further improvement is necessary.

Abstract

The invention discloses a side-inserted mounting and fixing mechanism for an intercooler. The side-inserted mounting and fixing mechanism comprises an intake manifold (200), the intercooler (100) arranged in the intake manifold (200), at least one bulge (120) formed in the top of the intercooler (100) and at least one fixed hole (220) formed in the intake manifold (200), wherein the fixed holes (220) and the bulges (120) are connected in a mode of one-to-one correspondence. The side-inserted mounting and fixing mechanism optimizes the reliability of the intercooler arranged in the intake manifold, reduces the potential risk of the service life of an engine, meanwhile reduces the dimensional tolerance requirement of the manifold and the intercooler, further reduces the manufacturing workload, and ensures the mounting operability of the intercooler and the manifold.

Description

technical field [0001] The invention relates to the technical field of supercharged engines, in particular to an installation and fixing mechanism of a side-inserted intercooler on an intake manifold. Background technique [0002] With the development of the economy, people's requirements for the living environment continue to increase, and the country's requirements for engine emissions continue to increase. In order to meet the emission standards formulated by the state, the existing engines all adopt supercharging and intercooling technology to reprocess the exhaust gas, so as to improve engine performance and reduce emission pollution. The role of turbocharging is to increase the density of air entering the cylinder by increasing the intake pressure, thereby increasing the amount of air charged, so that more fuel can be supplied and greater power can be obtained. The temperature of the air after the intake is high. In order to improve the intake efficiency, the high-tem...
