Abstract
The utility model provides a double-row overlap welding steel pipe radiator which comprises an upper header, a lower header and upright post pipes, wherein both sides of each of the upper header and the lower header are uniformly and respectively provided with an upper notch and a lower notch of two rows of corresponding welding upright post pipes; the upright post pipes are overlapped and welded with the upper notch and the lower notch of the upper header and the lower header, and the upright post pipes are connected with end enclosures of the upright post pipes. The utility model can solve the problems that welding face is small through the conventional welding of a radiator, and the welding face need burnishing, which results in low welding intensity, heavy workload of welding mouth burnishing and short life time.
Description
Technical field
The utility model relates to building heating equipment, specifically a kind of double overlap welding steel pipe radiator.
Background technology
At present, the kind that is used for steel pipe type radiator is a lot, and the last lower linked box of radiator and column tube mostly adopt conventional welding, has that solder side is little, its solder side needs polishing, causes the defective that weld strength is low, weld bond polishing workload is big, service life is short.
Summary of the invention
The purpose of this utility model provides a kind of double overlap welding steel pipe radiator, and it can solve, and the existing solder side of the conventional welding of radiator is little, its solder side needs polishing, causes the problem that weld strength is low, weld bond polishing workload is big, service life is short.
The purpose of this utility model is achieved through the following technical solutions: double overlap welding steel pipe radiator, comprise upper linked box, lower linked box and column tube, the both sides of upper linked box, lower linked box are respectively equipped with the upper notch of double corresponding welding column tube, following recess equably, the upper notch of column tube and upper linked box, lower linked box, following recess overlap welding connect, and column tube and column tube end socket join.Said column tube and upper linked box, lower linked box connecting position adopt with the column tube equivalent diameter and press the arc process structure.Upper notch on upper linked box, the lower linked box, following recess are connected by the welding of pad scolder overlap joint with column tube.The tubular of column tube is oval.The tubular of column tube is rectangle.The tubular of column tube is square.
The beneficial effects of the utility model are: press the arc process structure to make because the upper and lower connecting position that connects case and column tube adopts with the column tube equivalent diameter, make column tube become the faying surface welding with the upper and lower box-shaped that connects, therefore improved weld strength; Again owing to adopt pad scolder mode that radiator overlap joint weld bond exterior appearance must not polished, solder side is big and firmly, thus have safe and reliable, the life-span is long, cost is low, simple in structure, yield rate is high and take the little advantage of the interior space.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1, shows the ordered state of double column tube 2;
Fig. 3 is the upper notch 4 that is connected with column tube 2 respectively on the upper linked box 1 among Fig. 1, the lower linked box 6, the local enlarged diagram of following recess 5.
The specific embodiment
Double overlap welding steel pipe radiator of the present utility model, comprise upper linked box 1, lower linked box 6 and column tube 2, it is characterized in that: the both sides of upper linked box 1, lower linked box 6 are respectively equipped with the upper notch 4 of double corresponding welding column tube 2, following recess 5 equably, column tube 2 and the upper notch 4 of upper linked box 1, lower linked box 6, recess 5 overlap joint welding down, column tube 2 joins with column tube end socket 3.Column tube 2 adopts with column tube 2 equivalent diameter with upper linked box 1, lower linked box 6 connecting positions and presses the arc process structure.Upper notch 4 on upper linked box 1, the lower linked box 6, following recess 5 are connected by the welding of pad scolder overlap joint with column tube 2.When the utility model is made, according to the heat sink size that designs, cut upper linked box 1, lower linked box 6, column tube 2 and column tube end socket 3, processing gets final product according to the method described above again.The optimum shape of column tube 2 of the present utility model is oval, and the tube shape of column tube 2 can also be rectangle, and the tube shape of column tube 2 also can be for square.The technology department that the utility model is not described in detail is divided into known technology.
