Preparation method of ultra-thin automobile radiating circular pipe and automobile radiator

Abstract

The invention discloses a preparation method of an ultra-thin automobile radiating circular pipe. The method comprises the following steps that a solid-state high-frequency welding power source is used for welding a pipe barrel into a circular pipe with the outer diameter of 7.0-7.3 mm, the thickness of a wall is 0.20-0.25 mm, and cooling, slag scraping and cutting off are carried out to obtain the ultra-thin automobile cooling circular pipe; and the invention further provides an automobile radiator, the heat radiator is composed of the ultra-thin automobile heat dissipation circular pipe, turbulent flow fins, a reinforcing plate, a mounting plate, an upper water chamber, a lower water chamber and an aluminum comb plate. According to the method, a single-layer aluminum alloy material is adopted to prepare the automobile heat dissipation circular pipe, the material uniformity is good, a high-frequency current with a high-current and large-frequency is adopted for welding, so that the welding speed is high, the welding efficiency is high, a melting point of a welding position is consistent, and the anti-corrosion performance is good; and the wall thickness of the circular pipe is very thin, not exceed 0.25 mm, the heat exchange efficiency is high, the weight is light, a consumable material is saved, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of automobile radiators, in particular to a method for preparing an ultra-thin automobile heat dissipation round pipe and a round pipe radiator core. Background technique [0002] At present, in the automobile radiator industry, extruded aluminum tubes, high-frequency welded aluminum tubes or composite aluminum tubes are widely used as the main channel of the medium. Most of the existing aluminum tubes use smooth side wall tubes with elliptical cross-sections or flat The production process of this type of product is relatively simple, but in the production process of applying this product, especially in the assembly process of the radiator core, the heat dissipation pipe and the heat dissipation belt are assembled together, and the external force of the fixture will generate axial pressure. After the side is compressed, the deformation is serious, which leads to the deformation of the high-level bulge, and t...

Problems solved by technology

[0005] At present, the core body of automobile radiators is mostly tube-belt or tube-sheet type. The cross-section of the heat pipe is long waist-shaped, the pressure resistance is not high enough, there is no spoiler structure inside, and it is inconvenient to add a spoiler device, tube-band or tube-sheet Type core body, the number of heat pipes is large, it is not easy to assemble with the main chip, and the production efficiency is not high

Secondly, in the current automobile radiator, in order to prevent sundries and dust from blocking the radiator core, the generally used spoiler fins are rectangular waves, but the pressure on the contact points between the two sides of the heat pipe and the spoiler fins is small, The mechanical strength is not high. During the test and use of the radiator, the rectangular spoiler fins are squeezed and deformed due to the small pressure, and a bulge occurs in the middle part of the radiator shape, and the width direction of the radiator core increases.
