Thin-walled high-temperature-resistant high-pressure-resistant intercooler corrugated pipe

Abstract

The invention belongs to the technical field of cooling systems for commercial vehicles and particularly relates to a thin-walled high-temperature-resistant high-pressure-resistant intercooler corrugated pipe. The corrugated pipe is of a three-layer structure, and the three layers include the rubber pipe inner rubber layer, the rubber pipe reinforcement layer and the rubber pipe outer rubber layer; the rubber pipe inner rubber layer is made from fluorinated silicone, the rubber pipe reinforcement layer is a high-temperature-resistant four-layer aramid cloth, and the rubber pipe outer rubber layer is made from silicone; the two ends of the corrugated pipe are straight line segments, and the middle of the corrugated pipe is a corrugated segment; the corrugated segment is provided with a wavepeak structure and a wave trough structure; the included angle beta between the two sides of the wave peak is 75-105 degrees, the corner radius R1 of the outer surface of the wave peak is 8-11 millimeters, the corner radius R2 of the inner surface of the wave trough is 5-7 millimeters, the diameter D4 of the tangent circle of the outer surface of the wave peak is equal to the outer diameter D3 ofthe straight line segments and 9-11 millimeters, and the diameter D1 of the tangent circle of the inner surface of the wave peak is equal to the inner diameter D2 of the straight line segments minus8-12 millimeters. The corrugated pipe is low in weight, and the burst pressure at the normal temperature is larger than 2 MPa; the corrugated pipe has the advantages of being resistant to high temperature, high in strength and modulus, stable in size, low in shrinking percentage, resistant to heat and chemical corrosion, good in flexibility and dielectricity and the like.

Description

technical field [0001] The invention belongs to the technical field of commercial vehicle cooling systems, and in particular relates to a bellows tube of a thin-wall high-temperature and high-pressure resistant intercooler. Background technique [0002] At present, commercial vehicle manufacturers generally adopt supercharging and air-air cooling systems, which function to supercharge and cool the intake air of the engine, increase the density of the intake air of the engine, improve the combustion conditions of the engine, increase the engine power and meet the national environmental protection requirements. Require. [0003] On a turbocharged engine, intercooler bellows are usually required to connect the engine to the intercooler. With the continuous improvement of engine power and turbocharger compression ratio, the working temperature and pressure requirements of intercooler bellows are also getting higher and higher. At the same time, the bellows of the intercooler a...
