Summary of the invention

In order to overcome above-mentioned defective, the objective of the invention is: a kind of not only good heat dissipation effect is provided, and the biplate flanging that intensity is largely increased makes up radiating tube.

Technical scheme of the present invention is: comprise the body that the heat radiation thin slice and the thin slice that dispels the heat are down combined; The both sides of last heat radiation thin slice broad ways have flanging downwards one time; Form flanging place I, flanging place II; Flanging place I, flanging place II contact with last heat radiation thin slice formation face respectively, and the both sides of following heat radiation thin slice broad ways upwards have flanging one time, form flanging place III, flanging place IV; Flanging place III, flanging place IV contacts with following heat radiation thin slice formation face respectively, on the thin slice that dispels the heat lump together the formation body with the thin slice that dispels the heat down along the flanging soldering group.

Said going up on heat radiation thin slice and the following heat radiation thin slice has relative depression reinforcement along its length, and reinforcement links together up and down.

The invention has the beneficial effects as follows: the present invention is through changing the shape of body both sides; Both sides cause through the variable thickness that folding mode obtains the radiating tube different parts, form section thickness and do not wait, that is to say through change section thickness obtain high strength and with the unification of high heat dispersion; The area thickness of middle heat radiation is constant; Make radiating tube keep good performance of heat dissipation,, formed bigger wall thickness simultaneously requiring the higher both sides of mechanical performance; Thereby obtain the significantly lifting of each item mechanical performance; Anti-ly shake, tension, performance such as high pressure resistant, shock-resistant all have and significantly improve, and when increasing various mechanical performances, the part that middle wall thickness is thin still keeps good heat dispersion.The present invention can be widely used in cooling systems such as motor vehicle, engineering machinery and farm machinery, change exchange system.
