DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic
wave generating method and apparatus for absorbing and removing heat generated by vibration
of an oscillator of an ultrasonic wave generator with a heat absorber connected to the oscillator.
is there. Heretofore, in an ultrasonic wave generator intended to irradiate ultrasonic vibration to
a small scattering medium of thermal diffusion, as shown in FIG. The heat generated by the
vibrator increases and the temperature of the vibrator is degraded, and the heat from the
vibrator is directly emitted from the radiator 2 to the target medium ( In order to prevent thermal
damage etc. of the target medium, it is transmitted to the irradiation object), and in order to
prevent them, temperature control to cool the periphery of the radiator by water cooling etc.
However, there are various disadvantages such as the inability of continuous radiation because of
the unreliability of the device and the need for cooling in the middle of radiation, and in recent

years, ceramic ultrasonic transducers have come to be widely used. But these oscillators It is a
high-dielectric material compared to conventional quartz etc., and application of high frequency
voltage is required to keep the drive of the vibrator, so the temperature rise is even larger and
temperature control is especially heavy EndPage: 1 is necessary, it is simple Proper temperature
control or long awaited. Therefore, in the present invention I, a high thermal conductivity
material is connected to the transducer, heat generated by the transducer is exchanged by
absorption into the high thermal conductivity material, temperature rise of the transducer is
suppressed, and an ultrasonic radiation surface Is a simple device that can control the
temperature of the body, and only connect a high thermal conductivity material to the vibrator,
and heat the medium to which the temperature rise is limited or when the skin of the human
body or animal is exposed to ultrasonic waves The effect is minimized, the vibration
characteristics of the vibrator itself are improved, and the remarkable effect of preventing the
damage due to the heat of the ultrasonic irradiation object is present. Referring now to the
attached drawings illustrating the embodiments of the present invention, reference numeral 1
denotes an ultrasonic transducer made of quartz, ceramics or the like. Reference numeral 2
denotes a container, in which the ultrasonic transducer 1 is connected to the inside of the
container 2 and also serves as an ultrasonic radiator, the thickness of the ultrasonic radiator 2 in
contact with the ultrasonic transducer IK is the transducer The thickness according to the
wavelength constant of the vibration frequency of 1. Reference numeral 3 is a heat absorber
having a thermal conductivity higher than that of the ultrasonic radiator 2 and made of a metallic
material of acoustic transmission loss and having a cooling capability. 4.4 is an ultrasonic
transducer electrode attached to the upper and lower sides of the ultrasonic vibration f1, 5.5 is
an electric wire connected to the electrodes 4 and 7. -7 embodiment] FIG. 1 (as shown in FIG. The
heat absorber 3 is interposed between the ultrasonic transducer 1 and the ultrasonic radiator 2,
and the heat absorber 8 is provided so as to surround the transducer].
At this time, the heat from the vibrator] achieves the intended purpose of the flow in the
direction of the arrow in FIG. Embodiment 2 As shown in FIG. 2, the ultrasonic transducer 1 is
interposed between the ultrasonic wave emitter 2 and the heat absorber, and the heat from the
transducer 1 is transmitted in the direction of the arrow in FIG. It is. EXAMPLE 3 As shown in
FIG. 3, this example is a combination of Example 1 and Example 2, and the heat from the vibrator
1 is radiated more than in Example 1.2. It has an effect of not transmitting to the body 2.
Embodiment 4 As shown in FIG. 4, a plurality of ultrasonic transducers 1 are connected, and a
heat absorber 3 having a thickness according to the wavelength constant is interposed between
the same electrodes of two transducers. That is, it is possible to appropriately implement
according to the heat generation amount of the vibrator 10 according to one or more of the first
to fourth embodiments. Since the present invention has a configuration such as i-h or more, heat
generated by the vibrator 1 is not directly transferred to the radiator, but heat is absorbed and
heat is exchanged to suppress the temperature rise of the vibrator l to suppress the temperature
increase. Those that emit sound waves efficiently have remarkable industrial value in
