Abstract
The invention discloses a thermoacoustic driven stirling engine and belongs to the field of applications of thermomotors. The thermoacoustic driven stirling engine is formed by four core components namely a high pressure air storage bottle, a hot chamber, a power air cylinder and a motor; the power air cylinder is communicated with the hot chamber by arranging an air descending channel; the hot chamber is communicated with the high pressure air storage bottle by arranging an air ascending channel; an air valve is arranged in the middle of the air ascending channel; an integral structure which is formed by the high pressure air storage bottle, the hot chamber and the power air cylinder except the motor is total sealing; the interior of the integral structure is filled with high-pressure working medium gas which can be hydrogen, helium, nitrogen or air and the like. Compared with the traditional stirling engine, the thermoacoustic driven stirling engine does not adopt easy-to-wear moving components such as a distribution piston or an air remover, but moves the air through cold and hot space which is formed by the high pressure air storage bottle and the hot chamber, so that the reliability of the engine is greatly improved. The thermoacoustic driven stirling engine can be applied to a temperature difference and waste heat power generation system and a solar photo-thermal power generation system.

Background technique
Stirling engine is that the pastor Luo Bate Stirling (Robert Stirling) in London was invented in 1816, so called after " Stirling engine ".Stirling engine is the external-burning type heat engine, and there is airtight Working medium gas (available hydrogen, nitrogen, helium or air etc. are as working medium) its inside, presses the Stirling periodic duty.Its theoretic efficiency, no better than intrinsic peak efficiency, is referred to as Carnot's cycle efficiency.
The advantage of Stirling engine is: it does not have the quick-fried acting problem of shake of traditional combustion engine, is the motor of high efficiency, low noise, low pollution and low operating cost, can utilize solar energy, underground heat, chemical energy, nuclear energy equal energy source to make its operation.
The shortcoming of Stirling engine is: traditional Stirling engine is typically provided with gas distribution piston or moves this class of gas device moving element easy to wear, it needs power consumption and has increased a potential source of trouble in movement process, thereby, reduced the reliability of motor and shortened working life of motor.
Summary of the invention
Purpose of the present invention, be to overcome the deficiencies in the prior art, a kind of simple in structure, science is provided, structure rationally, gas distribution piston is not set or moves this class of gas device moving element easy to wear, the substitute is the hot and cold interval that adopts high-pressure gas cartridge and hot cell to form and move gas, reliability is high, and manufacture cost and operating cost is the hot acoustic Stirling motor of low-down popular style all.
To achieve these goals, " Stirling engine that a kind of heat is sound-driving " provided by the invention is by high-pressure gas cartridge, hot cell, actuating cylinder, this four large core component of motor (current collection moves with electricity generate function in the motor of one) forms, by a downtake is set, actuating cylinder is connected with hot cell, by air flue on is set, hot cell is connected with high-pressure gas cartridge, the middle part of upper air flue is provided with air valve, except motor, the a whole set of structure that above each member forms is totally enclosed, be hedged off from the outer world, its inside has been full of the Working medium gas of high pressure, Working medium gas can be hydrogen, nitrogen, helium or air etc.
Power piston, connecting rod, the flywheel that described actuating cylinder is inner by it and supported that the engine shaft of flywheel forms, the other end of engine shaft is provided with big belt pulley.
Described motor, its central shaft is motor shaft, an end upper support of motor shaft plays small belt pulley.
The interlock of described engine shaft and motor shaft is: on big belt pulley and small belt pulley, a drivign belt be complementary with them is set, its diaxon can be linked.
Described hot cell is an airtight member, its front portion is heating plate, and the periphery of this heating plate is thermal source, the Working medium gas transferring heat energy that thermal source is indoor by the heating plate thermotropism be clipped in the middle, this hot cell is exactly between the hot-zone of a high temperature in fact, and its temperature is 600 ℃～800 ℃.
Its rear portion of described high-pressure gas cartridge is provided with gas charging valve, and between the air storage cold-zone that this whole high-pressure gas cartridge is exactly a high pressure in fact, the pressure of its internal working medium gas is 1.5Mpa～20Mpa.
Different from the Stirling engine of prior art, the present invention's " Stirling engine that a kind of heat is sound-driving " does not arrange gas distribution piston or moves the power consumption such as gas device and moving element easy to wear, the substitute is be provided with cold, between hot-zone, combine to move gas with it, in the middle of, high-pressure gas cartridge is between cold-zone, hot cell is between hot-zone, in addition, the actuating cylinder structure that has retained traditional Stirling formula motor, by upper air flue and downtake are set, the three is connected, during work, the Working medium gas of high pressure is made expanded by heating in totally enclosed three intervals, meet the motion of cold compression, vibration back and forth again and again like this, the pressure wave of Working medium gas does work to the power piston in actuating cylinder, make its motion, this kinetic energy makes electric machine rotation by the transmission device of engine interior again, sending electricity comes.Adopt the present invention; reduced the source of trouble; the structure that makes motor is simpler, rationally and science; its reliability is higher than free piston type Stirling linear electric generator (it phenomenon of shutting down because of gas leakage often occurs); its manufacture cost and operating cost are far below photovoltaic generation, and its manufacture cost of every kilowatt is 1/4 of Guang Fu Unit crystal silicon battery, and its operating cost is 1/7 left and right (can realize low electricity price networking) of photovoltaic generation; and pure transformation efficiency doubles above than photovoltaic generation.
