Specific embodiment
In conjunction with accompanying drawing, the present invention is described as follows：
In figure is the structure of bionical pulsating heat pipe of the present invention：Evaporimeter, fin, chain box cupling, liquid injecting mouth, nozzle structure, absolutely
Hot arc, condensation segment, evaporator section.
By screwed chain box cupling, evaporator section and adiabatic section are connected, be conducive to installation and the mass of pulsating heat pipe
Produce；
Pulsating heat pipe is first vacuumized by the present invention from liquid injecting mouth, then from the working medium of injection certain volume so that filling rate is
70%, then close liquid injecting mouth；
After evaporator section is heated, fluid channel is distributed to each heat dissipation region and again converges by the bionical fluid channel of evaporimeter.Examine
Considering the dispersion of coolant and convergence is reversible process, and the left and right sides of runner can also be mirror-image structure, therefore by individual layer stream
Road is reduced to, along the symmetrical mirror image of square two diagonal, draw heat source region by square two diagonal
It is divided into the big delta-shaped region of four grades, slightly adjust the topological structure of the side of double-deck fluid channel, diagonal along two, square
