Example Embodiment
[0025] Example one:
[0026] Such as figure 1 , figure 2 As shown, a preferred embodiment of the present invention includes a stress bolt 1, a cylindrical back cover 2, a piezoelectric ceramic element 3, a conical front cover 4 with a series of holes in the radial direction, a negative electrode lead 5, and a positive electrode. Lead wire 6, pulsating heat pipe 7, multiple sets of heat conducting fins 8, liquid-filled pipe 9, condensation section 10, adiabatic section 11 and evaporation section 12.
[0027] The cylindrical back cover 2, the piezoelectric ceramic element 3, and the conical front cover 4 with a series of holes in the radial direction are tightly combined by the stress bolt 1 to be processed into a cylindrical piezoelectric ultrasonic transducer. The positive side of the piezoelectric ceramic element 3 is opposed to each other, and a thin copper sheet is sandwiched as the positive lead end of the piezoelectric ultrasonic transducer; the negative side of the piezoelec...
