Description

Technical Field

[0001] The utility model belongs to the technical field of air outlet pipes, and in particular relates to an air outlet pipe for an intercooler of an automobile engine. Background Art

[0002] The intercooler system is an important part of the normal operation of the supercharged engine. Its function is to reduce the temperature of the high-temperature gas after turbocharging, increase the intake volume, and thus achieve the effect of increasing the engine power. The intercooler outlet pipe is an important part connecting the intercooler assembly and the engine throttle.

[0003] At present, the pressurized gas discharged from the intercooler will pass through the outlet pipe, and the outlet pipe generally adopts a flexible hose. In this way, the excessive pressure of the gas discharged from the intercooler can easily cause damage to the outlet hose. In addition, the hose is prone to swinging significantly during the process of conveying pressurized gas, especially in the part of the outlet pipe close to the outlet of the intercooler, where the air flow pressure is greater. If this part is not restricted, it is easy to affect the overall stability of the outlet pipe. Utility Model Content
