Column leaf periphery, column leaf is between main body cylinder block and radiating sleeve.The beneficial effect is that: the setting of radiating sleeve further improves scattered
Thermal effect, if it can use liquid cold soaking formula refrigerating mode without radiating sleeve；Air-cooled mode can be used equipped with radiating sleeve, is used
Radiating sleeve enables to cylinder body that can preferably radiate in the environment of high temperature and pressure.
In some embodiments, main body cylinder block is cylindrical type cylinder body, and the outer wall of one end of main body cylinder block is equipped with annular
Leakage-proof socket, sealing ring is equipped in leakage-proof socket.The beneficial effect is that: cylinder body is played under liquid cold soaking formula radiating mode to be prevented sewing
Effect.
In some embodiments, cylinder main body and column leaf are structure as a whole, and radiating sleeve is smelted in main body cylinder block and column leaf
Periphery.The beneficial effect is that: cylinder main body and column leaf are structure as a whole, and manufacture convenient for one-pass molding；At present on the market using cold
But liquid is undesirable come the inserted cylinder sleeve heat dissipation cooled down, because indirectly cooling cause cylinder body metal to be easy fatigue, in order to solve cylinder
Body heat dissipation is undesirable, and cylinder body metal is easy fatigue, and the directly cooled liquid immersion type cooling of multicolumn leaf cylinder body (not having radiating sleeve) can
To solve the above problems.Radiating sleeve is smelted when using wind-cooling heat dissipating mode solves this and asks in main body cylinder block and column leaf periphery
Topic, heat dissipation are good.
In some embodiments, the inner wall of radiating sleeve is equipped with the groove that matches with column leaf, on the outer wall of radiating sleeve
Equipped with multiple cooling fins, cooling fin is multiple be arranged in parallel along the circumferencial direction setting around main body cylinder block, cooling fin.It has
Beneficial effect is: the setting of multiple cooling fins increases heat dissipation area, and thermal diffusivity is good.
In some embodiments, it is additionally provided with the support portion perpendicular with cooling fin on the outer wall of radiating sleeve, support portion is
It is multiple.The beneficial effect is that: support portion increases heat dissipation area perpendicular to cooling fin setting and strengthens the solidness of radiating sleeve.
In some embodiments, the material of main body cylinder block and column leaf is the steel alloy of antiwear heat resisting corrosion resistant.Its is beneficial
Effect is: so that cylinder body antiwear heat resisting corrosion resistant, solidness are good.
In some embodiments, heat dissipation cover material is aluminium alloy.The beneficial effect is that: aluminium alloy thermal diffusivity is good.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
FIG. 1 to FIG. 5 schematically shows a kind of internal combustion engine cylinder block of embodiment according to the present utility model.
As shown, the internal combustion engine cylinder block includes main body cylinder block 1 and column leaf 2, column leaf 2 be it is multiple, multiple column leaves 2 are parallel and
The even periphery that main body cylinder block 1 is set.
Above-mentioned internal combustion engine cylinder block, the periphery of main body cylinder block 1 are arranged multiple column leaves 2 and form 2 cylinder body of multicolumn leaf, increase
More heat dissipation areas, while also enhancing the solidness of cylinder body, cylinder body can be made to radiate well in the case where high temperature and pressure, made
The metal for obtaining cylinder body maintains a good state, and lays good basis further to promote the compression ratio of engine.
Internal combustion engine cylinder block further includes radiating sleeve 3, and radiating sleeve 3 is coated on 2 periphery of main body cylinder block 1 and column leaf, column leaf 2
Between main body cylinder block 1 and radiating sleeve 3.The setting of radiating sleeve 3 further improves heat dissipation, it can be cold using liquid immersion
