Summary of the invention
At above-mentioned technical problem to be solved, main purpose of the present invention provides the metallic crystal device of a kind of reasonable in design, applied widely, good effect of heat exchange, energy-conservation employing ultrasonic wave cavitation reinforcement.
The technical scheme that the present invention takes is as follows, and a kind of metallic crystal device that adopts ultrasonic wave cavitation reinforcement is characterized in that, the superturbulent flow cooler crystallizer with ultrasonic wave cavitation reinforcement also includes:
Ultrasonic signal generator is used for sending high-frequency signal;
Transducer, transducer are installed on the housing of crystallizer and the ultrasonic signal generator wire coupling, are used for receiving high-frequency signal and produce ultrasonic vibration.
The further setting of the present invention is: crystallizer comprises crystallizer or crystallization plates, crystallizer or crystallization plates are the hollow closed, the hollow bulb of crystallizer or crystallization plates is a condensing zone, it is suitable that the crystallizer housing is arranged at the periphery of crystallizer or crystallization plates and crystallizer or crystallization plates, crystallizer housing outer periphery is equipped with water-cooling system, comprise a water stream channel, and cooling water inlet and coolant outlet, cooling water inlet and the coolant outlet composition water-cooling system that is connected with water stream channel respectively, be separately installed with transducer on the two end plates of crystallizer housing, ultrasonic signal generator connects by lead mutually with transducer.
Another object of the present invention provides a kind of metal cooling means that adopts ultrasonic wave cavitation reinforcement, may further comprise the steps: send high-frequency signal by ultrasonic signal generator, make transducer produce ultrasonic vibration, cooling water in the crystallizer is produced the ultrasonic cavitation effect, make cooling water become the superturbulent flow state, strengthen cooling.
The fouling of crystallizer housing is effectively cleaned and prevented to ultrasonic vibration, improves cooling effect.Simultaneously, send high-frequency signal, make crystallizer produce ultrasonic vibration by ultrasonic signal generator, to crystallizer carried out ultrasonic vibration by crystal metal, crystal grain thinning improves the crystal metal mechanical performance.
Operation principle of the present invention is as follows:
Ultrasonic cavitation is in the liquid because ultrasonic physical action, a certain zone in liquid can form local temporary transient negative pressuren zone, so in liquid, produce hole or bubble. these bubbles that are filled with steam or air are in unsteady state, when they are closed suddenly, can produce shock wave, thereby at the very big very big pressure of local tiny area generation, thereby the sound field energy that gathers together is discharged rapidly in the minimum space in liquid, form thundering high temperature (can up to more than the 5000K), high pressure (can be up to 5x10
7Pa) and extreme physical conditions such as strong shock wave and jet.Ultrasonic cavitation is intersected and is comprised the fluid coring, cavitation is initiated, the dynamic behaviour of cavitation cavity, a lot of physics such as sound chaos and cavitation effect and chemical phenomenon, the crystallizer heating surface is constantly washed away in the microjet effect that ultrasonic cavitation produces, increase the less turbulence of fluid at heat transfer interface, reduce the bound thickness of conducting heat, thereby increase heat transfer coefficient, making liquid is the superturbulent flow state.The reinforcement cooling of ultrasonic crystallizer, reason also is: (1) ultrasonic wave has cleaning action, cleans the dirt that passes heat-transfer area automatically, and dirty pull-up is fallen or attenuation, heating surface is kept clean, thereby reduce dirtiness resistance.
Beneficial effect of the present invention is as follows: the present invention is by applying ultrasonic vibration in cooling water, make cooling water produce the ultrasonic cavitation effect, the very little superturbulent flow state that also becomes of flow rate of liquid, strengthen cooling effect, make crystallizer produce ultrasonic vibration, crystallizer carried out ultrasonic vibration, crystal grain thinning by crystal metal.Compared with prior art have the following advantages:
1, cooling capacity improves;
2, energy savings;
3, ultrasonic wave has the antiscale cleaning action to crystallizer, can keep long-term high heat exchange efficiency.
4, reduce mold structure.
5, improve the crystal metal mechanical performance.
