Interior weldering column radiator
Technical field
The utility model relates to heating radiator technical field, relates in particular to interior weldering column radiator.
Background technology
What the header tube of existing steel column radiator adopted is common steel tube, and can only be from outside weldings after heat dissipation element combination, and the many and weld seam in welding dead angle exposes.Its shortcoming is: water-flowing amount is little, affects heat dissipation capacity, and weld seam exposes not attractive in appearance, and many because of welding dead angle, poor sealing performance, easily causes leakage, and service life is short.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of welds heat dissipation element in upper and lower header, makes the outside no-welding-seam of radiator, not only attractive in appearance but also ensured the weld strength of radiator.
For achieving the above object, technical scheme of the present invention is: comprise upper and lower header and pillar heat dissipation element, it is characterized in that upper and lower header is all pressed into semi-surrounding shape by sheet material, upper and lower header bilateral symmetry has the hole of some tubing shapes, insert respectively in the hole of upper header and lower collecting box at pillar heat dissipation element two ends, at upper header and lower collecting box inside, upper and lower header and heat dissipation element is welded into enclosure space respectively.
Owing to adopting technique scheme, the upper header of radiator and lower collecting box are pressed into semi-surrounding shape, bilateral symmetry is gone out the hole of some tubing shapes, make heat dissipation element become possibility in header interior welds, weld seam does not expose without polishing, and not only attractive in appearance but also ensured the weld strength of radiator, heat dissipation element is respectively managed and inserted welding in header tube, make thermal source little at the inner heating agent circulation resistance of radiator, radiating effect is better than outside weld radiator.

Detailed description of the invention
Embodiment mono-: as accompanying drawing 1a, 1b, shown in accompanying drawing 2, comprise upper and lower header 1,2 and pillar heat dissipation element 3, it is characterized in that upper and lower header 1,2 are all pressed into semi-surrounding shape by sheet material, upper and lower header 1,2 bilateral symmetry has the hole of some tubing shapes, and insert respectively in the hole of upper header and lower collecting box at pillar heat dissipation element 3 two ends, at upper header and lower collecting box inside, upper and lower header and heat dissipation element are welded into enclosure space respectively, and weld with argon arc welding.
Pillar heat dissipation element is to make with tubing.After pillar heat dissipation element and upper and lower header weld, upper and lower header is rolled into close-shaped.
Embodiment bis-: as shown in Figure 3, its structure and embodiment mono-are basic identical, its difference is heat dissipation element 3 to insert respectively in upper header 1 and lower collecting box 2, welding from upper header 1 and lower collecting box 2 respectively, after pillar heat dissipation element and upper and lower header weld, be welded into the header of sealing by header cover plate and upper and lower header, header cover plate is pressed into " C " shape section bar by sheet material and makes.
