Description
Technical field
The present invention relates to a kind of Stirling engine, particularly designs its arrangement.
Background technology
Stirling engine is a kind of outer combustion-ing engine, and it is different from internal combustion engine, and it absorbs heat outside cylinder, by its work
Make medium（Gas）Heating, by the way that when gases are heated, they expand, compresses to the cold to produce power.When the hot head of continuous heating engine
（Heat dump）, make the working media matter expansion of inside, promote piston movement, expanding gas are recycled to cold air chamber and carry out cooling receipts
Contracting, repeatedly cyclic process as progress.Four cylinder Stirling engines are exactly that the gas circuit of four cylinders is cascaded, finally
Piston is mechanically connected by two bent axles, connecting rods, realizes that mechanism is run.
This external-combustion engine needs temperature end and low-temperature end, is operated using temperature difference, one in the engine body
It is the high-temperature and high-pressure cavity that create a working media（It is made up of the top half and hot head of piston）, when working media is by returning
After hot device and cooler, low-temperature end was cooled to by coolant（The latter half of piston）, so as to realize that Stirling starts
The working cycles of machine.When working media vibrates between high and low temperature chamber, piston up-down, and logical side bent axle, connecting rod will be living
The conversion of motion of plug is the rotary motion of bent axle, realizes power output.And the engine housing needs the work to different cylinder bodies
Medium is cooled down, and keeps the medium of each cylinder not connected in cooling, and this just brings difficulty to engine structure design.It is existing
The each cylinder cooling medium of four cylinder Stirling engines be also independent, employ more pipeline, it is complicated.
The content of the invention
The technical problem to be solved in the present invention：In view of the above-mentioned problems, provide four highly integrated cylinder Stirling engines
Body structure.
Technical solution of the present invention：
A kind of four highly integrated cylinder Stirling engine body structures, including casing and four working cylinders, its feature exist
In：Box house has interlayer to be divided into space two layers up and down, and four working cylinder matrix patterns are vertically installed at box house and passed through
Interlayer, the lower semisection outside wall surface and casing lower layer space composition coolant high temperature chamber of four working cylinders, the upper half of four working cylinders
Sheaf space forms coolant low temperature cavity in section outside wall surface and casing, and four gas coolers, gas cooler are installed on the outside of casing
On pipeline coolant high temperature chamber is connected with coolant low temperature cavity, the inlet and outlet of coolant sets up separately in casing both sides.
The cooling liquid inlet of low temperature but liquid low temperature cavity is opened on wall box, and four working cylinder centers are high temperature coolants
Outlet duct, high temperature coolant outlet duct are connected through coolant low temperature cavity with the cooling liquid outlet on wall box.
Gas high-temperature region in working cylinder is connected with gas cooler lower end by pipeline, the gas low temperature area in working cylinder
Connected with gas cooler upper end by the perforation in cabinet wall structure.
Two layers of air flue is offered on the interlayer of casing, respectively as feeding pneumatic and return-air gas circuit.
There are four gas cooler mounting surfaces and an air manager mounting surface on cabinet exterior）, air manager peace
Dress face is located at below cooling liquid outlet, installs air manager on air manager mounting surface, air manager connects confession respectively
Gas gas circuit and return-air gas circuit.
Casing top is installation position of drive shafting.
Beneficial effects of the present invention：
This body structure makes full use of cabinet space of knowing clearly, and the coolant between four gas coolers connects in casing
Logical, the gas working medium of each cylinder body shares identical coolant and cooled down while keeping separate, ingenious rational
Body structure is designed, and the cavity of working media flow and the high temperature chamber and low temperature of coolant are formed using the casing of casting
Chamber so that casing realizes functional requirement with simplest structure.The space between four working cylinders is utilized to cast out in casing cold
But the cavity of liquid, upper chamber are coolant high temperature chamber, have a delivery port on casing；Lower cavity is the low temperature of coolant
Chamber, have a water inlet on casing, it is achieved thereby that four cylinders and even, respectively by a total inlet and outlet pipe with starting
The cooling system connection of machine.By installing cooler in four, outside the enclosure portion plane, high-temperature gas is allowed to carry out heat with coolant
Exchange, while also achieve the connection of two chambers in casing, coolant is realized circulation.
According to the operation principle of four cylinder Stirling engines, body structure is optimized, be integrated with casing it is high,
Cryogenic liquid cavity and its entry and exit, the mounting plane of each cylinder cooler, piston seat mounting plane, air manager installation
Plane, the cooler mounting plane of 4 cylinders, the connection of gas circuit is realized using the method that hole is processed in tank material, is avoided
The challenge of outside the enclosure portion installation pipeline so that four cylinder Stirling engine body structures and peripheral parts are subtracted
Change, the size of four cylinder Stirling engines can be greatly reduced, and due to being internally integrated substantial amounts of water route and gas circuit, reduce
The installation number of outer tube, also improve the reliability of Stirling engine.
