As one preferably, on same second fin, from fin root（Connecting portion i.e. with base tube 1）To fin
Between top, the density in hole 23 is constantly reduced.Main cause is that, from fin root to fin top, the temperature of fin is continuous
Decline, therefore the thickness of boundary region is constantly reduced, the density in the hole 23 by arranging change, it is possible to achieve destruction boundary region
The thickness of diverse location, so as to save material.
Preferably, the PTAT example relation in the change of the density in hole 23 and fin.
Preferably, for the width b2 between the second fin is changed according to certain rule, concrete rule is
From the base angle of isosceles triangle to drift angle, the width of the second fin 18 extended from two waists of isosceles triangle is increasingly
Greatly, the end from the drift angle of isosceles triangle to the first fin 17, the second fin 19 extended from the first fin 18 are wide
Degree is less and less.Main cause is the second fin arranged in waist, and heat dissipation capacity gradually increases from base angle to drift angle, therefore needs
The area increased by radiating, therefore by increasing the width of fin increasing the area of dissipation of fin.In the same manner, along first
Fin 18, from bottom to end, the quantity of radiating is fewer and feweri, therefore the corresponding area for reducing fin.By such
Arrange, can greatly improve radiating efficiency, while greatly material-saving.
Preferably, from the base angle of isosceles triangle to drift angle, from the second radiating that two waists of isosceles triangle extend
The amplitude that 18 width of piece increases is increasing, from end of the drift angle of isosceles triangle to the first fin 17, from the first radiating
The amplitude that 19 width of the second fin that piece 17 extends is reduced is less and less.It is found through experiments, by above-mentioned setting, with increase
Or reduction amplitude is identical compares, it is possible to increase about 16% radiating effect.Therefore there is good radiating effect.
