Stainless Steel Welded Component of Small Backpack Heating Radiator and Manufacturing Method

Abstract

The invention discloses a stainless steel welded component of a small back basket type heating radiator and a manufacturing method thereof. For the bent horizontal tubes that are not on the same vertical plane, the two kinds of horizontal tubes are respectively connected with two vertical connecting pipes. There are two rows, and there is an angle between the two rows of ring flanges. The straight horizontal tube and the bent horizontal tube are made of thin-walled stainless steel tubes. In the two rows of circular flanges of the pipe, the pipe wall is closely fitted, the end faces are flush, and the end faces are welded to form a circular weld; the vertical connecting pipe is made of strip-shaped stainless steel sheet, and it is curled into a closed cross-sectional shape along the length direction at the closure There is a pair of protruding bar-shaped flanges, and the upper end faces of the bar-shaped flanges are welded to form a bar-shaped weld.

Description

technical field [0001] The invention belongs to the technical field of civil radiators, and relates to a stainless steel welded component of a pantry-type heating radiator and a manufacturing method thereof, in particular to a pantry-type heating radiator made of thin-walled stainless steel. Background technique [0002] Small back basket heating radiators have been widely used in residential homes. The main structure of a common small back basket heating radiator is: it includes two vertical connecting pipes arranged symmetrically on the left and right, and a number of them arranged up and down are distributed on the same Straight horizontal tubes on a vertical plane, the two ends of the straight horizontal tubes are respectively connected to two vertical connecting tubes, and there are multiple bends with bends at both ends that are not on the same vertical plane as the straight horizontal tubes The horizontal pipe is connected with two vertical connecting pipes at both en...

AI Technical Summary

Problems solved by technology

In the known prior art of a stainless steel welded structure radiator, the communication pipe is provided with an outwardly protruding annular flange, and the row pipes to be connected are inserted and welded outside the annular flange of the communication pipe, or Insert and weld the row pipes to be connected in the annular flange of the connecting pipe. For these two through connection methods, the welds are all on the outer surface, which affects the appearance of the stainless steel. When the welding temperature is unstable, especially for Thin-walled stainless steel materials are very prone to weak welding or breakdown, and at the same time, the heat transfer medium will penetrate into the gap between the annular flange of the connecting pipe and the row pipe, which may corrode the weld seam; in addition, this prior art The row pipes are all arranged in the same plane between the two connecting pipes, and it is impossible to realize the through connection between the bent horizontal pipes and the vertical connecting pipes that are not on the same plane as in the small pannier radiator
