The invention relates to an ultrasonic heating device which comprises a control cavity and a heating rod. The control cavity is provided with a wiring port, a control switch, a handle and the like. When the control switch is closed, high-frequency current produced by an ultrasonic power supply is input into a piezoelectric plate located in the heating rod through a first high-frequency lead wire and a second high-frequency lead wire, the piezoelectric plate produces high-frequency vibration under the effect of the high-frequency current and transfers the high-frequency vibration to a matched layer, the matched layer transfers the high-frequency vibration to a fluid around the heating rod in an ultrasonic mode, and accordingly the fluid is stirred and heated. The ultrasonic heating device can heat high-viscosity, low-heat-conductivity and flammable fluids, acoustic energy in the high-viscosity fluid quickly dissipates through ultrasonic heating, and the heating effect is good. The acoustic streaming enables mixing and stirring to be accelerated, and heating of the low-heat-conductivity fluid can be accelerated. In addition, the acoustic energy has good energy delivery performance, the local temperature of the fluid is not overhigh, and the flammable fluid can be safely heated.
Description
technical field [0001] The invention relates to a heating device, in particular to an ultrasonic heating device. Background technique [0002] Ultrasonic heating is a physical phenomenon of high-intensity ultrasound. Acoustic energy causes molecules and macromolecular groups in the medium to vibrate, and then the vibration energy is converted into heat energy, which increases the temperature of the medium. It actually originates from the inconsistency caused by the relaxation effect in the medium when the ultrasonic vibration energy propagates in the medium. Avoided energy absorption and conversion. Ultrasonic heating has been used in the fields of focused ultrasonic burning of cancerous tumors, ultrasonic physiotherapy, ultrasonic welding and other fields. [0003] The current fluid heating methods are mainly heat exchangers and electric heating, which can meet the requirements in most cases, but for some special cases, such as high viscosity, low thermal conductivity, fl...
