Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As shown in Figures 1 to 4, the liquid cooling cylinder body 1 of this rotary polygonal piston engine, comprising: cylinder body 1, lateral surface is laterally opened
Several screw connecting columns 3 are longitudinally evenly arranged with equipped with liquid cooling slot 2, on cylinder body 1, each screw connecting column 3 runs through liquid cooling
Slot 2 and 3 side of screw connecting column is resisted against 2 inner wall of liquid cooling slot；Liquid cooling shell 4, identical as 2 shape of liquid cooling slot, the lid of liquid cooling shell 4 is set
It is fixedly connected on liquid cooling slot 2 and 4 side of liquid cooling shell with cylinder body 1, inlet opening 5 and fluid hole 6 is offered on liquid cooling shell 4；It is cold
But liquid enters liquid cooling slot 2 by inlet opening 5 and passes through 6 efflux cold trap 2 of fluid hole.
Liquid cooling slot 2 is laterally opened on cylinder body 1, and liquid cooling shell 4 is covered on liquid cooling slot 2 and 4 side of liquid cooling shell and cylinder body 1 are solid
