Abstract
The utility model relates to a Stirling engine. In the structure, a cold cavity and a hot cavity are respectively arranged at the two ends of a U-shaped device, and are connected through a regenerator; a gas mixing piston is arranged on the bottom of the U-shaped device; and a working piston is arranged in the cold cavity. The U-shaped device is filled with liquid, so the pressure can be transmitted through the liquid after the working piston cavity and the hot cavity of the engine are separated. Thus the Stirling engine avoids the long-term work of the piston at high temperature, and reduces the manufacturing difficulty and the requirements for the material. The movement of the gas mixing piston can lead to the upward and downward lifting of the liquid level of the cold cavity and the hot cavity at the two ends of the U-shaped device, so as to realize the compression and expansion of the gas working substance. A wire mesh is arranged in the cold cavity and the hot cavity at the two ends of the U-shaped device. Thus the heat exchanging area can be expanded, so as to improve the heat exchanging speed and the volume-power ratio.
Description
Affiliated technical field
The utility model relates to a kind of Stirling engine.
Background technique
At present, most effective in the known gas engine with Stirling engine, but its summation watt rating is than low, the heat-resisting of material had relatively high expectations, and manufacture cost is higher, and the working medium sealing technique is difficult, the reliability of Sealing and life-span also have problems etc., so not popularization and application.
Summary of the invention
Not enough in order to overcome more than the existing Stirling engine, the utility model provides a kind of Stirling engine, this Stirling engine not only summation watt rating is more higher than low, thereby and can seal easily and reduce the manufacturing technology difficulty and to the requirement of material, reduce manufacture cost.
The technological scheme that its technical problem that solves the utility model adopts is: cold chamber and hot chamber are separately positioned on " U " type device two ends, and cold chamber links to each other by regenerator with hot chamber, and gas distribution piston places " U " type bottom of device, and the acting piston places cold cavity segment.In " U " type device liquid is arranged, the acting piston cavity of motor is separated the back by liquid transfering pressure with hot chamber like this, has avoided piston long-term work at high temperature, reduces manufacture difficulty and material requirements.Utilize the gas distribution piston motion to cause the lifting of " U " type cold chamber, device two ends and hot chamber liquid level to realize the compression and the expansion of gas working medium, in the cold chamber at " U " type device two ends and the hot chamber wire gaze is arranged, can increase heat exchange area, thereby improve rate of heat exchange, do high summation watt rating ratio.
The beneficial effects of the utility model are to improve the summation watt rating ratio of Stirling engine.Heat-resisting requirement of material and difficulty of processing reduce, and have reduced manufacture cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a sectional structural map of the present utility model.
1. hot chambeies among the figure, 2. regenerator, 3. wire gaze, 4. cold chamber, 5. acting piston, 6. gas distribution piston bar, 7. gas distribution piston.
Embodiment
In the drawings, the hot chamber (1) at " U " type device two ends links to each other by regenerator (2) with cold chamber (4), in hot chamber (1) and the cold chamber (4) wire gaze (3) is arranged all, acting piston (5) places cold cavity segment, gas distribution piston (7) places " U " type bottom of device, and its gas distribution piston bar (6) is through the outer wall both sides of " U " type device.
When making the liquid level in cold chamber (4) when moving right, gas distribution piston (7) rises, the liquid level in hot chamber (1) descends, gas enters the interior expanded by heating acting in hot chamber (1), transmit pressure by liquid and promote acting piston (5) motion, rise when gas distribution piston (7) makes the liquid level in hot chamber (1) during to left movement, the liquid level of cold chamber (4) descends, and gas enters interior the heat release contraction in cold chamber (4), thereby make the backhaul of acting piston (5), finish a circulation.
Gas distribution piston (7) can limit by the out of phase on rhombus-mechanism or the same bent axle with the action relationships of acting piston (5), and is same as the prior art.
Gas distribution piston bar (6) equates the pressure of gas distribution piston (7) left and right sides through the outer wall both sides of " U " type device, is beneficial to moving and control of gas distribution piston (7).
In hot chamber (1) and cold chamber (4) wire gaze (3) is arranged all, the effect of wire gaze (3) is the heat exchange area that increases hot chamber (1) and cold chamber (4) and gas working medium, liquid and the rapid heat exchange of wire gaze when the intraluminal fluid face rises, when the intraluminal fluid face descends by wire gaze and the rapid heat exchange of gas working medium that enters, accomplish that promptly fast heat is cold soon, thereby improve the summation watt rating ratio.
The regenerator of regenerator (2) structure and function and existing Stirling engine is identical, in this heat release, absorbs heat at this when living hot chamber (1) by cold chamber (4) when its effect is a gas working medium by hot chamber (1) toward cold chamber (4).
Claims (4)
1. a Stirling engine comprises cold chamber, hot chamber, gas distribution piston, acting piston and regenerator, it is characterized in that: cold chamber and hot chamber are separately positioned on " U " type device two ends.
2. Stirling engine according to claim 1, the piston that it is characterized in that doing work places cold cavity segment.
3. Stirling engine according to claim 1 is characterized in that gas distribution piston places " U " type bottom of device, and its gas distribution piston bar is through the outer wall both sides of " U " type device.
4. Stirling engine according to claim 1 is characterized in that in this cold chamber of " U " type device and the hot chamber wire gaze being arranged.
