Description
Technical field
The present invention relates to a kind of ultrasonic ultrasonic delay line memory.
Background technology
Ultrasonic ultrasonic delay line memory is a high-power ultrasonics transducing oscillator, core is to be made of atomizing piece and corresponding electronic circuit, atomizing piece is referred to as the transducing sheet at electronic applications, during atomizer work, atomizing piece with frequency of ultrasonic vibration water, makes hydrone generation sharp impacts and produces gas in water.
In order to realize the purpose of high-power ultrasonics vibration, usually include powerful transistor in the electronic circuit of ultrasonic ultrasonic delay line memory.At present, this high power transistor usually and other electronic circuit partly form an integral body, promptly be positioned on the circuit board at other electronic devices and components place, rely on air to dispel the heat, this kind constructional device, the weak point of existence is: the volume of (1) circuit board is big, relatively heavier.Because high power transistor must be fastened on the fin, and the contact area of fin and air is big more, its radiating effect is good more.Thus, make that the volume of electronic circuit board of traditional ultrasonic ultrasonic delay line memory is big, relatively heavier; (2) cost height.Above-mentioned fin is aluminum alloy materials normally, needs to consume non-ferrous metal, causes its production cost to raise; (3) the reliability variation of circuit.Because high power transistor is in high hot state, during the ultrasonic ultrasonic delay line memory long-term work, the electronic device around this high power transistor inevitably is subjected to the influence of high temperature, especially for electronic components such as capacitors, its service behaviour will reduce, and causes the reliability variation of circuit.
Summary of the invention
At the deficiencies in the prior art, the special proposition ultrasonic ultrasonic delay line memory that a kind of volume is little, cost is low, reliability is high of the present invention.

For power transistor 5 is protected better, can also be, shell 7 is set, a little silicone grease is smeared on power transistor 5 surfaces, also can smear and fill other heat endurance and heat conductivility excellent material; Shell 7 is sleeved on the power transistor 5, and passes housing 1; In shell 7 and housing 1 lower surface junction, adhere to encapsulant 6, can prevent that the water in the housing 1 top water container 10 from penetrating into housing 1 bottom and damaging electronic circuit 2, can be dispersed in the water of housing 1 top water container 10 by the heat of shell 7 with power transistor 5 again.Smear a little silicone grease on power transistor 5 surfaces, mainly, power transistor 5 is assembled easily in order to strengthen heat conduction efficiency between shell 7 and the power transistor 5.The material of above-mentioned shell 7 can be the material of good heat-transfers such as glass, copper, stainless steel, corrosion-resistant oxidation.
When actual embedding encapsulant 6, the part encapsulant may flow into the cavity volume between shell 7 and the power transistor 5, so can possess water-proof function better.
In order to survey the height of water level automatically, avoid the dry combustion method problem, the present invention can also be provided with water level detector 4.It mainly acts on is to survey water surface elevation in the water container 10, and when water surface elevation was lower than the height of setting, water level detector 4 control electronic circuits 2 quit work ultrasonic vibration generator 3, in order to avoid damage ultrasonic vibration generator 3, promptly usually said dry combustion method phenomenon.Water level detector can and independently be arranged on water level switch in the water container 10 for mechanical float-ball type or electronic measurement and control formula, and indirect and electronic circuit 2 are electrically connected and control the work operating mode of ultrasonic vibration generator 3.Secondly, water level detector 4 can also be electronic type and the water level switch that directly is electrically connected with electronic circuit 2, described water level detector 4 is fixedly mounted on the top of housing 1, its electrode was worn housing 1 and was electrically connected with electronic circuit 2, lower surface junction at water level detector 4 and housing 1, be attached with encapsulant 6, can prevent that the water in housing 1 upper container from penetrating into housing 1 bottom and damaging electronic circuit 2.
What specify is, for guaranteed output transistor 5 has water in the course of the work all the time it is dispelled the heat, and the failure of oscillation water level that water level detector 4 or its set should be greater than or equal to the top of power transistor 5 as far as possible.
Above-mentioned encapsulant 6 is good insulation preformances, ageing-resistant such as a kind of resinae or viscose glue class, and preferably possesses the electrical material of certain flowability.
Above-mentioned ultrasonic vibration generator 3 is general purpose modules of ultrasonic ultrasonic delay line memory, it is fixed in housing 1 bottom, and be electrically connected with electronic circuit 2, its atomizing piece transducing sheet in other words passes predefined hole on the housing 1 and is exposed to the upper face of housing 1, directly contacts with water liquid in the housing 1 top water container 10.It mainly acts on is converting the mechanical oscillation of high frequency to from the higher-order of oscillation large-current electric signal of electronic circuit 2, and the mechanical vibrational energy of this high frequency is the atomization of liquid in the container slot.
Above-mentioned electronic circuit 2 is control centres of ultrasonic ultrasonic delay line memory, be assembled on the circuit board, and being fixedly mounted on housing 1 bottom, electronic circuit 2 is electrically connected by lead and external power, also is electrically connected with ultrasonic vibration generator 3, water level detector 4, power transistor 5 simultaneously.
The upper face of housing 1 is provided with groove 9, in the groove 9 sealing ring is set.Water container 10 is set, its underpart opening, and with housing 1 fixed seal connection, transducing sheet, water level detector 4, the power transistor 5 of ultrasonic vibration generator 3 are immersed in the water simultaneously.
Secondly, can be connected sealing with housing 1 with a cavity volume shell body, the electrical part of housing 1 bottom is all sealed, like this, the ultrasonic ultrasonic delay line memory of formation can be placed on arbitrarily in the water receptacle independently, and water is atomized.
The course of work of the present invention is: the present invention and water container 10 fixed connection and sealing, and in water container 10, add water, connect external power, electronic circuit 2 produces the big current oscillation of high frequency, the big current oscillation of this high frequency frequency passes to ultrasonic vibration generator 3, the high-frequency mechanical vibration of ultrasonic vibration generator 3 makes the atomization of liquid in the water container 10, and simultaneously, the heat that power transistor 5 produces is dispersed in the water in the water container 10.If the liquid in the water container 10 is less, when reaching the height of setting, water level detector 4 actions, electronic circuit 2 sends control signal, makes ultrasonic vibration generator 3 failure of oscillations, in order to avoid damage this device.
In sum, beneficial effect of the present invention is: (1) volume is little, in light weight.Because the power transistor 5 among the present invention is installed in the top of housing, directly dispels the heat by water, need not to be provided with in addition large-area fin, therefore, greatly reduces the volume of ultrasonic ultrasonic delay line memory, has alleviated the weight of ultrasonic ultrasonic delay line memory; (2) cost is cheap relatively.Owing to saved large-area metal fin, reduced the consumption of non-ferrous metal, saved production cost.(3) reliability height.Because the electronic component in the electronic circuit 2 is away from the power transistor 5 of high heat, its functional reliability greatly improves.
