Means for diverging 7 in the present invention is separately mounted in branch pipe(tube) I 16 and branch pipe(tube) II 26, is mainly used for branch pipe
Water in road I 16 or branch pipe(tube) II 26 is dissipated, by taking punch-pin 1 as an example, when water enters heat dissipation cavity I by branch pipe(tube) I 16
When 12, then water frontal impact punch-pin wall 13 is dissipated in irregular turbulence state, causes the flow velocity of water different, heat absorption
Efficiency it is uneven, so that punch-pin wall 13 is absorbed heat unevenly, finally make mode buckling deformation, and the impeller 72 of means for diverging 7 is installed
In branch pipe(tube) I 16, when water impact, water flow dynamic energy is on the one hand reduced, another aspect impeller 72 rotates, leaf
Wheel 72 drives flabellum 73 to rotate synchronously by shaft 71, and the rotation of flabellum 73 dissipates the water for entering heat dissipation cavity I 12 around, will
Turbulent flow becomes laminar flow, and the flow velocity of water is more stable.
The rubber hose III 33 is provided with Pneumatic water pump 35.Cavity plate is in stationary state always, therefore adopts
It is that Pneumatic water pump 35 recycles the water in heat dissipation cavity II 22.
