Description
Affiliated technical field
The present invention relates to a kind of operating mode controller, be specially the hot machine operating mode of a kind of Stirling controller.
Background technique
On December 19th, 2007, behind the Stirling reversible heat engine application Chinese patent, its vitals countercurrent flow formula regenerator, circular heat exchanger are respectively on January 5th, 2011, application on January 26th, 2011 Chinese patent.The hot machine of Stirling of three Chinese patent formations is simple and compact for structure, is very perfect solution.The online paper of delivering on June 13rd, 2006 of Chinese science and technology paper " research of novel Stirling engine design theory " has been set up the Stirling reversible heat engine mathematical model, has proposed professional technique new ideas such as ground angle, operating angle.
So far, Stirling reversible heat engine structure and design theory are very ripe, make it drop into practical application, and control system is most important! On April 9th, 2010, the academic exchange that " automobile-used Stirling engine control system " has been invited to do in second academic conference of Sichuan Province's Deyang City, this paper have proposed starting braking and the operating mode control problem solution that Stirling reversible heat engine is made motor car engine.And be that example is set forth with the hot machine of four active chamber Stirlings.Starting braking and operating mode control system are made up of 10 parts such as high-pressure working medium jar, starting brake monitor, working medium equalizer chamber, deceleration valve, acceleration valve, reduction valve one, reduction valve two, back-pressure valve, low pressure working fluid jar, working medium suction boosters; by 3 signal source controls such as starting brake control signal, rotor phase signal, operating mode control signals, finish 4 kinds of operations such as starting, acceleration, deceleration, shutdown.The annexation of each parts as shown in Figure 1.Square frame is represented parts or signal, and the direction of arrow is represented working medium flow direction or signal transfer direction.Working medium equalizer chamber wherein is the core component of operating mode control, the force value of working medium control fuel oil, air delivery volume in it; Amount of the fluctuation of the force value of working medium control working medium turnover active chamber is also just controlled the increase and decrease of output work in it, is exactly in fact control work condition.So working medium equalizer chamber is the operating mode controller just.
The operating mode controller is one Stirling reversible heat engine working medium equalizer is concentrated in the seal container, by the pressure of working medium in the control seal container, control working medium amount and fuel-air delivery volume, thereby the device of control work condition.
Summary of the invention
The objective of the invention is to design a kind of operating mode controller as the hot machine control system of Stirling core component.
To achieve these goals, the solution of the present invention is: its structure comprises the operating mode controller core and the operating mode controller shell that have a plurality of one-way valves, safety valve.Operating mode controller in-core, many identical working medium flow channels that distribute are centrosymmetric.Article one, the working medium flow channel has three connection mouths, lays respectively at the two ends and the side of operating mode controller core.The connection mouth attachment security valve or the one-way valve of one end and side, a working medium flow channel connects a safety valve, an one-way valve, and another connection mouth is on the operating mode controller core base plate perpendicular to symmetrical center line.Operating mode controller shell opener end and operating mode controller core base plate intersect, and form a confined space that contains all safety valves and one-way valve.A pressure transducer jack, two working medium turnover connection mouths are arranged on the operating mode controller shell.
Connection mouth on the described operating mode controller core base plate and the corresponding one by one connection of active chamber.
Two connection mouths on the described operating mode controller shell, one is connected with acceleration valve, and another is connected with deceleration valve, and the pressure transducer in the pressure transducer jack is connected with the fuel-air provisioning controller.
It is the working medium flow channel that flows into operating mode controller core from confined space that the working medium of the one-way valve of described operating mode controller flows to, and realizes quickening.
The working medium flow direction of the safety valve of described operating mode controller is the working medium flow channel inflow confined space from operating mode controller core, realizes slowing down.
The invention has the advantages that: the one, a plurality of working medium equalizer are concentrated on the operating mode controller core, place in the very little confined space, through-flow volume is minimum, can sensitive control.The 2nd, the operating mode controller is connected on the regenerator temperature near normal temperature one end, not in the secondary seal chamber, the operating mode controller has the control function in former secondary seal chamber, and the secondary seal chamber only has sealing function, without the contradiction of two kinds of functions of balance performance, control and sealing effect are better.The 3rd, manufacture cost significantly reduces.
