[0055] 1. The horizontal pipe and vertical pipe are shaped by a
one-off extruding, the cover panel and through-hole are blanked by
a one-off punching, and assembly is finished by a one-off welding
in a soldering furnace. The main body of the radiator is shaped
into a vertical-pipe radiator which has overcome the disadvantages
in coil-pipe type radiator of simplex circulation line and too many
detours that block circulating and in plate type radiator of low
resistance to pressure that will make the radiator distort or
deform or make the weld points crack and so on.
[0056] 2. The main parts are shaped by extruding, and thus the
machining technique is simple and reliable with low cost and high
rate of finished products. The vertical pipe, horizontal pipe and
the bar fins at the end of horizontal pipe are shaped by one-off
extruding which increases the heat radiating area by 8.about.10
times and improving the heat transferring efficiency by
60%.about.80% comparing with existing products.

production.
[0058] 4. Bar fins are added to the surface of the vertical pipe
and horizontal pipe to enlarge the effective heat radiating area
and decrease the number of welding points.
