Utility model content
The utility model provides a kind of Stirling engine cylinder cooling device in view of the deficiencies of the prior art, and feature exists
In：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, cold
But liquid passes through helical metal pipe（2）Metal tube import（4）It is pumped into, cylinder（1）Coolant liquid is transferred heat to, is then cooled down
Liquid is exported by metal tube（3）Heat is taken out of, then coolant liquid passes through coolant duct（5）, radiator（6）After cooling,
Passing through pump（7）And coolant duct（5）It is pumped into helical metal pipe（2）It is interior, it circuits sequentially；Helical metal pipe（2）Material
Fusing point be greater than cylinder（1）The fusing point of material；Coolant liquid should have antifreeze function, can be realized by addition anti-icing fluid；Spiral
Shape metal tube is directly loadable into mold when cylinder is cast, and cylinder has cast rear screw shape metal tube and has been embedded in cylinder.
The beneficial effects of the utility model are：
Cylinder material is changed to aluminium alloy, alleviates cylinder weight, and installation difficulty reduces；The pyroconductivity of aluminum alloy material
Greatly, after cooperation coolant liquid is cooling, cylinder heat dissipation effect can be made to greatly enhance；Be conducive to the promotion of engine overall power density；
Helical metal pipe is directly loadable into mold when cylinder is cast, and cylinder has cast rear screw shape metal tube and has been embedded in cylinder.
Helical metal pipe can guarantee the slickness and ride comfort of cooling liquid flowing channel；The helical structure of helical metal pipe can also have
Effect promotes the heat-transfer capability between coolant liquid and cylinder wall, and coolant liquid is flowed by cylinder top, lower part outflow, flow direction it is whole to
Under, with flowed up in cylinder working medium flow direction on the contrary, facilitate increase heat convection, enhance cooling effect.
