Engine be it is a kind of can be the machine that can be converted into mechanical energy of other forms, including such as internal combustion engine (gasoline hair
Motivation etc.), external-combustion engine (Stirling engine, steam engine etc.), motor etc..If internal combustion engine is usually that chemical energy is converted into machine
Tool energy.Engine is not only suitable for power generating apparatus, also can refer to include power device entire machine (such as: petrol engine, boat
Empty engine).Engine is born in Britain earliest, so, the concept of engine is also derived from English, its literal sense refers to that
" mechanical device for generating power ".Body is the skeleton for constituting engine, is the installation foundation of engine each mechanism and each system,
Its inside and outside all major part and attachment for being installed with engine, bears various load.Therefore, body must have enough
Strength and stiffness.Body group is mainly made of parts such as cylinder block, cylinder sleeve, cylinder head and head gaskets.
The prior art has the following problems: present durable type engine cylinder barrel structure is often simple, for a long time with piston
Friction generates heat influences structural stability and service life in the condition of high temperature for a long time.
Utility model content
To solve the problems mentioned above in the background art.The utility model provides a kind of durable type engine cylinder barrel knot
The characteristics of structure has structure simple, and radiating efficiency is good, long service life.
To achieve the above object, the utility model provides the following technical solutions: a kind of durable type engine cylinder barrel structure, packet
Inner cylinder is included, the outer wall of the inner cylinder is provided with liner, and outer barrel, the table of the outer barrel are provided on the outside of the liner
Face is evenly arranged with partition, and the both ends of the partition are formed with radiating groove, and outer barrel surface corresponding with radiating groove is equal
Even to be provided with heat release hole, the upper end of the outer barrel and radiating groove opposite position are provided with venthole.
Preferably, the partition accounts for 40 the percent of the overall thickness of outer barrel.
Preferably, the heat release hole is set as the through-hole through outer barrel.
Preferably, the thickness of the partition and the thickness of radiating groove are equivalent to the half of radiating groove.
Preferably, the outer barrel opens up radiating groove close to middle position, the upper end setting of the venthole only outer barrel
Have.
Preferably, setting is integrated between the inner cylinder, outer barrel and liner.
Compared with prior art, the utility model has the beneficial effects that
The utility model is evenly arranged with partition by the surface of the outer barrel in the outside of liner, and the both ends of partition open up
There is radiating groove, is evenly arranged with heat release hole on outer barrel surface corresponding with radiating groove, is arranged between inner cylinder and outer barrel
There is liner, the heat that liner absorbs inner cylinder spreads out into radiating groove by heat release hole, and the upper end of outer barrel is corresponding with radiating groove
Position is provided with venthole, and heat in radiating groove is discharged, and then reduces the temperature of cylinder structure, rapid heat dissipation, stable structure,
Prolong the service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A-A schematic cross-sectional view of the utility model.
In figure: 1, venthole；2, partition；3, radiating groove；4, heat release hole；5, inner cylinder；6, outer barrel；7, liner.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model is the following technical schemes are provided: a kind of durable type engine cylinder barrel structure referring to FIG. 1-2, including
