Embodiment Construction

[0025] The drawings show various preferred embodiments of the present invention for purposes of illustration only. The structures and methods described by skilled artisans from the following discussion may alternative embodiments without departing from the principles of the invention.

[0026] 1 and 2 show a schematic structural diagram of an embodiment of the transducer of the present invention. The transducer consists of a sector-shaped magnetostrictive lamination (3), a coil (2) wound on the lamination window to generate a driving magnetic field, a central radiant tube (4), a lamination window (6), and a cooling medium channel (5). , 6), cooling medium input and output ports (7, 8), transducer drive power interface (9, 10). The magnetostrictive material selected for the transducer is an annealed nickel sheet with a thickness of 0.3 mm. The nickel sheet is processed into a fan shape according to a 1 / 4 circle, and the surface is oxidized and passivated to improve the insulat...

Abstract

The invention comprises: a magnetostriction component, a central pipe eradiator, a driving coil, a closed case, a cooling media channel, a bias magnet, a forced cooling mechanism. A group of magnetostriction materials is laminated to form ring-shaped or sector-shaped driving component; on the lamination there is a sector-shaped or hole-shaped window opened; the central pipe eradiator is connected to the radiating face of the magnetostriction component; the driving coil for generating magnetic field is located on the group of laminations; on the closed case there are an entrance and outlet of cooling media and a connector of magnet field power.

Description

technical field [0001] The invention belongs to the technical field of power ultrasonic transducers, and in particular relates to a ring-shaped centrally focused high-power ultrasonic transducer and a magnetostrictive high-power ultrasonic transducer with a forced cooling structure. Background technique [0002] Ultrasound has a very wide range of applications, especially power ultrasound can be used in processing, welding, cleaning, underwater detection, ultrasonic chemistry, etc. Therefore, various ultrasonic transducers with special structures have attracted widespread attention. The vibration core materials in ultrasonic transducers are mainly composed of two types of materials, one is piezoelectric crystal material and the other is magnetostrictive material. The current ultrasonic transducers are mainly piezoelectric transducers. This is mainly because magnetostrictive materials are mostly metal materials, and the resistivity of the materials is low. When working at hig...
