Description
Technical field
The present invention relates to Stirling engine technology fields, and in particular to a kind of Stirling engine cylinder cooling means.
Background technology
Former patent《A kind of modularization multi-cylinder Stirling engine with free piston》；The patent No.：201621251275.3
The cylinder used is finned radiator structure, and effect is poor, influences the power density of engine.Meanwhile former patent upper cylinder is adopted
Cylinder iron material manufacture, weight is big, and installation difficulty is big.
The content of the invention
The present invention provides a kind of Stirling engine cylinder cooling means in view of the deficiencies of the prior art, it is characterised in that：
Its structure is cylinder（1）Inside it is provided with helical metal pipe（2）, cylinder（1）One end is provided with metal tube outlet（3）, cylinder（1）
The other end is provided with metal tube import（4）, cooling means is that cylinder can generate heat when Stirling engine is run, and is cooled down
Liquid passes through helical metal pipe（2）Metal tube import（4）It is pumped into, cylinder（1）Coolant is transferred heat to, then coolant
It is exported by metal tube（3）Heat is taken out of, then coolant passes through coolant duct（5）, radiator（6）After cooling,
Pass through pump（7）And coolant duct（5）It is pumped into helical metal pipe（2）It is interior, it cycles successively；Helical metal pipe（2）Material
Fusing point is more than cylinder（1）The fusing point of material；Coolant should possess antifreeze function, can be realized by adding anti-icing fluid；Helical form
Metal tube is directly loadable into when cylinder is cast in mold, and cylinder has cast rear screw shape metal tube and has been embedded in cylinder.
The beneficial effects of the present invention are：
Cylinder material is changed to aluminium alloy, alleviates cylinder weight, and installation difficulty reduces；The pyroconductivity of aluminum alloy material is big,
It after coordinating coolant cooling, can greatly enhance cylinder heat dissipation effect；Be conducive to the promotion of engine overall power density；Spiral
Shape metal tube is directly loadable into when cylinder is cast in mold, and cylinder has cast rear screw shape metal tube and has been embedded in cylinder.Spiral
Shape metal tube can ensure the slickness and ride comfort of cooling liquid flowing channel；The helical structure of helical metal pipe can also be carried effectively
The heat-transfer capability between coolant and cylinder wall is risen, coolant is flowed by cylinder top, and lower part outflow, flow direction is whole downward,
With flowed up in cylinder working medium flow direction on the contrary, contribute to increase heat convection, enhance cooling effect.
