Stirling engine is when operation, due to continuous burning in the firing chamber of fuel outside cylinder, the working medium that is independent of combustion gas is absorbed heat by heater, and press Stirling circulation and externally do work, therefore avoid pinking acting and the intermittent combustion process of similar internal-combustion engine, thereby realized efficient, low noise and low emission operation.Efficient: overall energetic efficiency reaches more than 80%; Low noise: at the bottom of 1 meter of bare machine noise in 68dBA; Low emission: exhaust emissions reaches Europe 5 standards.
Because working medium is not burnt, external-combustion engine has been avoided the quick-fried acting problem of the shake of traditional combustion engine, thereby has realized high efficiency, low noise, low pollution and low operating cost.The external-combustion engine various inflammable gass that can burn, as rock gas, biogas, petroleum gas, hydrogen, coal gas etc., the also liquid fuel such as incendivity diesel oil, liquefied petroleum gas (LPG), can also burn wood, and utilizes solar energy etc.As long as hot chamber reaches 700 ℃, the equipment operation of can doing work, ambient temperature is lower, and generating efficiency is higher.The advantage of external-combustion engine maximum is to exert oneself not affected by altitude with efficiency, is very suitable for high altitude localities and uses.
Simultaneously Stirling engine remain subject matter and shortcoming be: manufacture cost is higher, and working medium sealing technique is more difficult, and reliability and the life-span of Sealing also have problems, and cost of material is high, and power adjustments control system is more complicated, and machine is comparatively heavy; The cost of expansion chamber, pressing chamber, heater, cooling chamber, regenerator etc. is high, and heat loss is 2-3 times of explosive motor etc.
Organic rankine cycle system comprises pump, vaporizer, decompressor, generator, condenser etc.Heat collector absorbs solar irradiance, and in heat collector, heat exchange medium temperature raises, and heat transferring medium is passed to organic working medium by vaporizer heat.Organic working medium is level pressure heating in vaporizer, and the gaseous state organic working medium of high pressure enters decompressor expansion acting, drives generator generating; The organic working medium that decompressor afterbody is discharged enters level pressure condensation in condenser, and the organic working medium of condensator outlet enters vaporizer and completes power generation cycle one time after pump pressurization.
Organic rankine cycle system exists conversion efficiency not high, and volume is large, need to be by baroque decompressor acting.
Radial engine is that a kind of cylinder is arranged a kind of reciprocating engine that is star-like arrangement around bent axle, and piston is connected on bent axle by a master connecting rod, and the connecting rod that the piston of the top connects is master connecting rod; The connecting rod of other piston is articulated connecting rod, and they are connected on the ring of master connecting rod middle position by tip hole.
It is large that radial engine has rigidity, lightweight, and reliability, maintenance and survivability are good, and flash-up potentiality are large, and rotating speed is high, deficiency be manufacture cost higher, to processing technology require high, to maintenance, require high.
Summary of the invention
The cost that the utility model has overcome the expansion chamber that external-combustion engine exists, pressing chamber, heater, cooling chamber, regenerator etc. is high, and heat loss is the problems such as 2-3 times of explosive motor; Having overcome organic rankine cycle system needs decompressor or steam turbine, the technical barrier that manufacture cost is high; Overcome the problem that internal-combustion engine radial engine structure is comparatively complicated, manufacture cost is high.The star-like negative pressure power equipment the utility model proposes is to have adopted existing radial engine structure, in conjunction with the thermodynamic apparatus of Stirling engine, organic rankine cycle system and internal-combustion engine radial engine advantage.To pull piston acting cylinder being carried out to cooling generation negative pressure after heat absorption.
The utility model provides that a kind of thermal energy conversion efficiency is high, can adjust working medium quantity within the scope of peak output adjusts output power, can adjust by adjusting temperature the negative pressure power equipment of output power, machine stable output power.
The technical solution adopted in the utility model is: a kind of star-like negative pressure power equipment, comprises connecting tube, breather check valve, gas exhausting valve, cylinder, piston, piston ring, connecting rod, bent axle, radiator, rotatingshaft and casing; Casing is provided with cylinder and is star-like arrangement around bent axle, and piston is connected on bent axle by connecting rod; In cylinder, be respectively equipped with piston, piston is provided with piston ring; Piston connects connecting rod, and connecting rod connects bent axle, bent axle connection of rotating axle, and rotatingshaft is fixed on casing by bearing; The top dead center of cylinder is provided with breather check valve and gas exhausting valve; Cylinder skin is provided with radiator; Cylinder head is provided with cylinder cap.
