Abstract

The utility model relates to an inside header type steeliness column radiator, which comprises a radiator uniwafer which is formed by an upper and lower header and a steel tube, a head flake and a rear flake of the radiator. Compared with other steeliness column model radiators, the utility model has the advantage of higher pressure, corrosion resistance, smooth and attractive figure, and the processing cost is reduced for 20%.

Description

Interior weldering header type steel column type heat radiator

Affiliated technical field:

The utility model relates to a kind of interior weldering header type steel column type heat radiator, belongs to field of heating.

Background technology:

The steel column type heat radiator of field of heating use now is mostly by water manifold and steel pipe combine up and down.Product pressure-bearing height, big, the Heat stability is good of heat dissipation capacity, the height of radiator, sheet number can be adjusted at any time according to the needs of area of dissipation, are easy to use flexibly.But because use and development that critical process welding method mode in this production process and effect affect this radiator always.Especially up and down the moulding of two ends water manifold welding, not only increased polishing operation process for back processing, influenced presentation quality, main is to cause the uneven distribution of weld seam even, in use having stayed the hidden danger that forms localized seepage's water because of the corrosion of water quality butt welded seam.At present, different welding methods is being inquired into by many producers, because it is complex-shaped, operation is too much, cost is too high, investment is excessive, also fails better to solve this difficult problem.

Summary of the invention:

The technical problems to be solved in the utility model: for the percolating water phenomenon that welding fabrication caused of the steel column type heat radiator water manifold that solves present use and reduce processing link, reduce cost, aesthetic in appearance, weldering header type steel column type heat radiator in the utility model design is a kind of, on this radiator behind the lower collecting box welding fabrication, weld seam is in header inside, the outside need not the secondary operations of polishing, not only be lowered into cost, and make this radiator pressure-bearing higher, life-span is longer, has solved the percolating water phenomenon that water tank causes because of processing method and long-term aqueous corrosion.

The technical scheme that its technical problem that solves the utility model adopts is: the shape that at first changes water manifold, make two R angles of former header into the radian big arc chord angle of trying one's best, the equally big water channel hole in former header two sides, with one of them dilated diameter, like this, can make welding rod stretch into header inside to reach the purpose of freely welding by macropore.As yet not before the butt welding moulding, carry out annealing in process in the punching press of header sheet,, reach the crystal phase structure that improves metal, increase its corrosion resistance to eliminate it because of the stress that punching press forms.The water manifold up and down of moulding and steel pipe are connected into the monolithic of radiator through flash of light welding or argon arc welding, by monolithic assembled formation the utility model radiator.In order to save material cost and accessory, first fin of radiator of the utility model design outside punching press of water manifold up and down protrudes blind plate replacement nut and mends core, lays air valve in the place's perforate of last blind plate.The water channel hole of the water manifold up and down of cauda adds the weldering nut and uses in order to installing.

The beneficial effects of the utility model are: because radiator is designed to arc chord angle and strengthens water channel hole in the R angle of water manifold up and down, reached the purpose that connects weldering in the case.Weldering header type steel column type heat radiator has been compared following advantage with other steel column type heat radiator in the utility model:

1, interior welds has changed the force direction that is subjected to of header weld seam, and pressure-bearing is higher, and security is good.

2, interior welds, weld seam have been filled up the interface in the header, the chronic corrosion that thoroughly solved the water quality docking port, and stress relieving by annealing in addition, thus prolonged life-span of header.

3, interior welds, profile is bright and clean attractive in appearance.

4, owing to the change of welding method and material, processing cost reduces by 20%.

Description of drawings:

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is a monolithic front view of the present utility model.

Fig. 3 is a monolithic side view of the present utility model.

Fig. 4 is a header inside weld schematic diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is further described:

1 is header among Fig. 1, Fig. 2, Fig. 3, Fig. 4; The 2nd, big mouthful of water channel; The 3rd, the water channel osculum; The 4th, the butt weld of header and steel pipe; The 5th, steel pipe; The 6th, the header inside weld; The 7th, header R angle; The 8th, the radiator cauda; The 9th, first of radiator; The 10th, first blind plate of radiator.

The specific embodiment:

Going up lower collecting box 1 as shown in Figure 4 all is made up of monolithic interior welds after annealing that drawing has big water channel 2 and draw 3 respectively.

As Fig. 2, shown in Figure 3ly be welded to form the radiator monolithic by last lower collecting box 1 and steel pipe 5.

The radiator of the utility model design begins the size of radiator monolithic according to radiator area need how much welding through

water channel

2,3 successively of monolithic radiator be combined by first 9 as shown in Figure 1, welds cauda 8 at last and forms.
