Cooling system of supersonic transducer

Abstract

The invention relates to an ultrasonic energy converter cooling system, wherein an ultrasonic energy converter comprising a magnetic core assembly carries out direct evaporative cooling on an inner cavity and an outer cavity of the ultrasonic energy converter. The system comprises a compressor, a condenser, a throttle element, an evaporator and an electro-acoustics conversion device. The evaporator comprises a main shaft, a radial slot, an annular channel, a double-ended bolt, a magnetic core assembly, a magnetic core inner cavity, a magnetic core outer cavity, a rear cover plate, an oil return slot, an upper casing, a decoupling ring, a decoupling oil gas hole, a lower casing, and a liquid inlet, wherein the liquid inlet is connected with a central hole of the double-ended bolt, and the two outlets of the central hole of the double-ended bolt are communicated with the magnetic core inner cavity. The ultrasonic energy converter cooling system adopts steam compressing regeneration principle to form regeneration circulation, the refrigerant takes away heat quality in the inner cavity of the electro-acoustics conversion device to make the ultrasonic energy converter to work in the predetermined temperature range under the action of the temperature control system.

Description

technical field [0001] The invention relates to a refrigeration technology, in particular to an ultrasonic transducer cooling system. Background technique [0002] During the conversion process of electric energy and sound energy, the ultrasonic transducer generates heat due to eddy current, and the temperature of the system rises, which may cause the performance of the transducer to attenuate or fail to work normally. At present, ultrasonic transducers with low power have relatively low heating power, so there is no need for a dedicated cooling system; for high-power ultrasonic transducer systems, there is no effective way to solve the problem of heat dissipation and cooling due to the high heating power . [0003] The thermal effect of eddy current: A coil is wound on a metal cylinder. When an alternating current is passed into the coil, the metal cylinder is in an alternating magnetic field. Due to the small resistance of the metal conductor and the large eddy current, ...
