Embodiment
Using existing design and Sheet Metal Forming Technology, the depth of the construction opening of mainboard flat tube groove is shallower, generally depth after shaping
1mm or so, no more than 1.5mm (sheet metal thickness of mainboard) can only be reached, so the later stage assemble after the completion of, flat tube with
Contact surface at mainboard cooperation is just shorter, the flat tube in later stage and the corrosion resistance of mainboard contact position, reliability, durability, strong
The poor-performings such as degree.In addition, obtaining mainboard flat tube groove using punching technology processing, section part is the form for removing material, so
Do not weld composite bed, the composite bed that can only be just leaned on flat tube in contact when radiator core body is welded complete welding,
Poor welding quality；In addition, under existing design, mainboard flat tube groove bottom is oriented to angle A ° in the range of 70 ° -80 °, angular aperture
Degree is larger, and the capillarity of the solder flux flowing in welding process between flat tube and mainboard flat tube groove is not obvious, is assembled with flat tube
When, guide effect is poor.
In consideration of it, the utility model designer devises a kind of radiator mainboard manufacturing process, radiator mainboard and dissipated
Hot device, punctures technique by the use of construction opening 120 on the flat tube 110 by radiator mainboard and is processed into, construction opening 120
Depth can be more than the thickness of the sheet material of mainboard in itself, and then add the contact area of flat tube 200 and mainboard, structure is more
Firmly；Meanwhile, the inwall of construction opening 120 has welding composite bed, is welded after the insertion construction opening 120 of flat tube 200
When, welding quality is high, and structure is more solid and reliable；During puncturing, mainboard is deformed upon, and guide angle is 140 degree smaller, is oriented to
Make good use of, enhance capillarity when mainboard is welded with flat tube 200, be more uniformly distributed solder flux flowing, mainboard connects with flat tube 200
Touch the filling of position solder flux more full, improve the reliability of welding.
