Problems solved by technology

Its main disadvantages are high production cost of high-frequency tubes or spoilers using double-sided cladding materials, low production efficiency of adding spoilers during assembly, high matching tolerance requirements, difficulty in applying flux, resulting in low brazing rate
The brazing strength is poor, which affects the service life of the product. Therefore, the development of a new type of cooling tube and production process for automotive intercoolers has always been a new subject to be solved urgently at home and abroad.

Abstract

The invention relates to the production process of cooling pipe for vehicles, starting with cutting aluminum bar with Phi100 into length of 380+- 5mm, heating it till 500-530deg.C, putting it to extrusion machine with special mold to compress the bar material with certain cross section, calibrating the extruded aluminum material, and cutting based on the required length, deburring and cleaning the residue inside and outside, with the product formed by tubes and oblique support barricades and up and below the tube being horizontal structures, both ends in arc structure, jointing part using arc transition. It is simplified in production process, good in molding plasticization, with finer molecule, reduced processes and dregs.

Description

Technical field: [0001] The invention relates to a cooling pipe for an automobile intercooler and a production process in the technical field of transportation tools. Background technique: [0002] At present, automobiles have become the main tools used by people in the transportation industry at home and abroad, and automobile intercoolers, as the main parts of automobiles, play a key role in improving the quality of automobile products. Environmental pollution is recognized as one of the three major public hazards in the world. It has been determined that a large part of urban air pollution comes from vehicle exhaust emissions. After the automobile intercooler is used in the automobile, in addition to increasing the engine power to achieve the purpose of energy saving, it also reduces the ambient air pollution caused by automobile exhaust emissions. Automotive intercoolers use cooling pipes as the main functional components. The traditional design is to use aluminum recta...
