Abstract
The invention discloses a zero-leakage stirling machine which relates to the technical field of thermal energy conversion, and aims to overcome the problems that the thermal conversion efficiency of the traditional internal combustion engine is low and the combustion is incomplete, and the costs of the expansion chamber, compression chamber, heater, cooling chamber refrigerator, and the like of the traditional stirling engines are very high, the power/weight ratio is small, the sealing is difficult, zero leakage cannot be realized and the like. The closed cavity of the stirling machine is connected with an external ventilation valve; when the internal system pressure of the Stirling engine is just equal to the external pressure value and the vetilation valve is then rotated by 20 degrees, the ventilation valve starts to open; the conduction angle of the ventilation valve 6 is 5 to 30 degrees; movably closed positions of all parts of the stirling machine and an external ventilation port of the ventilation valve are sealed in a closed shell; and the pressure of the gas working substance in the closed shell is 1 to 300p. The zero-leakage stirling machine can directly convert the combustion heat energy of fuel into mechanical energy with high efficiency, thereby realizing zero leakage and having extremely high power/weight ratio. The conversion efficiency is 20 to 80 percent.
Description
Technical field
What the present invention relates to is the technical field that thermal power transfer becomes mechanical energy.
Background technique
Existing internal-combustion engine is applied in the every field widely, wherein the quantity of automobile application is maximum, bring many facilities to the human lives, but its heat/machine conversion efficiency generally is between 20%～40%, all the other heat energy of 60%～80% can't utilize and need outwards discharging, simultaneously can not perfect combustions because of fuel, and its tail gas will discharge a large amount of dusty gass in air, make air be subjected to serious pollution, it is the one of the main reasons that cause earth environment to warm that tool is added up these.Brought loss and the destruction that to retrieve for human living environment in the future.
Stirling engine is that Stirling was in invention in 1816.Stirling engine is unique hot machine, because their theoretic efficient intrinsic peak efficiency no better than is called Carnot's cycle efficiency.Stirling engine produces power by when gases are heated, they expand, meet cold contraction.This is a kind of external-burning engine, and fuel is burnt continuously, and the expansion hydrogen (or helium) of evaporation makes piston motion as power gas, and expanding gas cools off at cold air chamber, carries out such cyclic process repeatedly.Because external-combustion engine has been avoided the quick-fried acting problem of shake of traditional combustion engine, thereby high efficiency, low noise, the low pollution and low operating cost have been realized.
But Stirling engine also has many problems to solve, and for example cost height, the power/weight ratio of expansion chamber, pressing chamber, heater, cooling chamber, regenerator etc. are little, and sealing difficulty and can't realize zero problem of revealing etc.So, can't become the motor of use in enormous quantities.
Summary of the invention
The present invention is in order to overcome existing internal-combustion engine thermal conversion efficiency low (between 20%～40%), incomplete combustion and in air the problem of a large amount of dusty gas of discharging, and existing Stirling engine exists also that costs such as expansion chamber, pressing chamber, heater, cooling chamber, regenerator are very high, power/weight ratio is little, and sealing difficulty and can't realize zero problem of revealing etc.And then a kind of Zero-leakage stirling machine proposed.
It comprises Stirling-electric hybrid, gas valve, gas working medium, closed shell;
The enclosed cavity of Stirling-electric hybrid is connected with an external gas valve, the conducting starting point of gas valve be Stirling-electric hybrid built-in system pressure just in time be in equal the ambient pressure value to rotate again 20 the degree between, the angle of flow of gas valve is that 5 degree are to 30 degree, the movable sealing place of above-mentioned all parts of Stirling-electric hybrid and the external breather port of gas valve all are enclosed in the closed shell, and the pressure of the gas working medium in the closed shell is 1～300 barometric pressure (pressurizeing under the situation that mechanical strength allows).
The rotating shaft of described Stirling-electric hybrid can with the generator interlock that is provided with in the closed shell, or be connected with the extraneous runner magnetic drives of closed shell by magnetic force.
The present invention can directly convert the combustion heat energy of fuel to mechanical energy efficiently, because of the outside all is a static seal, and can realize that zero reveals, thereby the pressure of its gas working medium can a very high (hundreds of barometric pressure, as long as mechanical strength enough just can), and then can realize the power/weight ratio of super large, further the volume of reduction means and reduce weight is realized energy-efficient.
The conversion efficiency of its heat energy/mechanical energy is 20%～80%, and heating-up temperature is high more, and its thermal conversion efficiency is high more.Its total part number is existing below 20% of the total part number of internal-combustion engine.
The material of its temperature end and the material of firing chamber are used current material and promptly may be realized, for example available existing high-temperature resistant pottery, and its heatproof is 1300 ℃～1700 ℃, or material such as stainless steel, and is promptly cheap for manufacturing cost, and can realize the purpose of production in enormous quantities sale.
Because fuel is to burn continuously, this just might be reduced to inferior limit to the pollutant of not wishing to produce outside, and then has reduced environmental pollution, promptly realizes perfect combustion.
It also have running steadily, noise is minimum, simple in structure, to material requirements is low, easy to use, maintenance cost is low, with low cost advantage.
