Double-column radiator and manufacturing method thereof

Abstract

The invention discloses a double-column radiator and a manufacturing method thereof. The double-column radiator of the invention comprises a lower beam, an upper beam and radiating pipes, wherein the upper beam and the lower beam have the same structure, and each of the upper beam and the lower beam comprises an upper cover and a bottom plate; the upper covers and the bottom plates are welded together through two abreast radiating pipes; connecting water nozzles are arranged on two ends of the upper beam and the lower beam, and are fixedly connected with the upper beam and the lower beam through nozzle sealing plates. The double-column radiator has no weak points in lateral connection and has high strength; when mounting, a colorful cap is mounted on the upper beam, so that the radiating effect of the radiator is improved and the integral appearance is more coordinated and attractive; when manufacturing, the welding position is flat edge welding, so as to omit the polishing process, reduce the welding difficulty, shorten the production process, reduce the labor intensity of workers, ensure the welding quality and improve the yield.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a double-column radiator and a manufacturing method thereof. Background technique [0002] National Patent No. 200710111389.7, the name of the invention is a steel radiator, a radiator with the radiator and its manufacturing method. The application discloses a steel radiator, which consists of an upper steel joint part and a lower steel joint. The upper steel joint part and the lower steel joint part are composed of a steel tubular part sealed and welded. The upper steel joint part and the lower steel joint part have the same structure. The half-shell parts are sealed and welded, the upper and lower half-shell parts have the same upper interface part and lower interface part respectively, and the upper interface part and the lower interface part are respectively sealed and fixedly installed with the same upper connection seat and lower connection seat . The disadvantage is th...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a double-column radiator and its manufacturing method, which can solve the problems of complex structure of the existing radiator, easy breakage of the horizontal connection port during transportation, difficulty in quality assurance and low yield rate, and the problem of the position of the welding point in the prior art. Many, welding is difficult, and the upper and lower joints are easily polished after welding with the heat dissipation pipe, resulting in uneven wall thickness of the radiator as a whole, and the reduction of its compression and impact resistance.
