露出せしめて冷却効果を高めてなる。 In the drawings, reference numeral 1 denotes a diaphragm corresponding to the wall surface of a cleaning tank, etc., and has stud bolts 2 on the main part of its outer surface. 3 connects a pair of piezoelectric elements 3a, 3a' to a terminal plate 3b
A pair of metal blocks 3 are placed on both sides of the
The radiation side metal block 3c has a blind screw hole 3d screwed into the bolt 2 of the diaphragm 1 on the outer end surface of the radiation side metal block 3c. 4 is a buffer plate made of synthetic resin such as vinyl chloride resin, acrylic resin, epoxy resin, etc., interposed between the diaphragm 1 and the metal block 3c on the radiation side of the vibrator; 5 is the metal block 3 on the radiation side of the vibrator.
A cooling plate made of a metal material with high thermal conductivity such as copper or its alloy is inserted between the metal block 3c and the buffer plate 4, and as shown in the figure, the diameter is larger than that of the metal block 3c and the outer periphery is exposed to achieve a cooling effect. It's getting higher.

と金属のクラツド材を用いてもよい。 In the above embodiment, a piezo-electrostrictive vibrator was used as the ultrasonic vibrator, but a magnetostrictive vibrator made of nickel, ferrite, etc. may also be used. 4. The cooling plate 5 is screwed together with bolts 2 as shown in the figure, or
They are attached together with an adhesive such as epoxy, or they are firmly joined using both these bolts and adhesive. Furthermore, a synthetic resin and metal cladding material may be used as the buffer plate and the cooling plate.
振動板に超音波振動子を接着剤などで直接接合

し、満足な緩衝効果が得られなかつた。 When an ultrasonic vibrator is directly bonded to a diaphragm with adhesive, etc., thermal and mechanical stress distortion occurs on the bonded surface due to temperature changes and uneven wave motion during use, causing the bonded surface to break in a short period of time. Therefore, a method is generally taken to insert a synthetic resin buffer plate between the bonding surfaces of the diaphragm and the vibrator to absorb the stress and strain, but the high heat generated in the vibrator can cause the buffer plate to become severely damaged. They often soften (if made from thermoplastic resin) or crack (if made from thermosetting resin), making it impossible to obtain a satisfactory cushioning effect.

るなど優れた効果がある。 In contrast, in this case, a cooling plate made of a metal material with high thermal conductivity is inserted between the joint surfaces of the vibrator and the buffer plate. It is possible to maintain a stable state at all times, exhibit sufficient buffering effect, and enable continuous operation over a long period of time.The cooling plate also serves as reinforcement for the buffer plate, making it easier to attach it to the diaphragm. It has excellent effects.
