The invention relates to a cylinder cooling device of an internal combustion engine. An internal end cover (1), an air inlet pipe (2), an air exhaust pipe (10) and an engine body (5) are arranged on a cylinder sleeve (7); a cooling liquid outlet (8) is designed on the engine body (5); a cooling liquid inlet (11) is designed on the air inlet pipe (2); an air inlet flange (3), an air exhaust port flange (9), twelve air exhaust ports (18), eighteen spiral flow guide grooves (16) and an oil injector installation boss (17) are designed on the cylinder sleeve (7); a small hole (14) is formed between every two adjacent air exhaust ports (18); the oil injector installation boss (17) is positioned between the spiral flow guide grooves (16); and a graphite ring (4) is arranged between attaching surfaces of the air exhaust pipe (10) and the engine body (5). The cylinder cooling device of the internal combustion engine has a good cooling effect and can prolong the service life of a cylinder.
Description
Technical field
The invention belongs to parts of internal-combustion engine, be specifically related to a kind of cylinder of internal-combustion engine cooling unit.
Background technique
The common cylinder type of cooling is divided into air-cooled and water-cooled at present.The cylinder liner of the air-cooled cylinder outside all is furnished with a large amount of radiating fin, and the fan that carries by internal-combustion engine is dried to radiating fin and dispelled the heat.Radiating fin has the effect of water conservancy diversion concurrently, and the guiding cooling air flows outside week in cylinder liner.The cylinder liner of water cooled cylinder middle part has water cavity, and when cylinder liner was installed on the body, water on the side of body, current flowed along the cylinder liner water cavity of each cylinder and takes away heat.Air-cooled and water-cooled cylinder liner is columnar structured, and assembling form is also roughly the same, all is that cylinder liner is installed on the cylinder block.The more air-cooled complex structure of the structure of water cooled cylinder, but the also just mobile cooling that can finish cylinder between the water cavity that two parts constitute of cooling fluid.These two kinds of type of cooling cooling effects are poor, can not effectively cool off each parts in the cylinder, reduced the working life of cylinder.
Summary of the invention
Technical problem to be solved by this invention provides a kind of cylinder of internal-combustion engine cooling unit, and this device can cool off cylinder of internal-combustion engine effectively, prolongs the working life of cylinder.
Technological scheme of the present invention: a kind of cylinder of internal-combustion engine cooling unit, it comprises inner end cap, suction tude, cylinder liner suction port, graphite annulus, body, body O type circle, cylinder liner, cooling liquid outlet, cylinder liner relief opening, outlet pipe, cooling liquid inlet, cylinder liner O type circle, body cooling sap cavity, aperture, cooling liquid bath, spiral stream guidance groove, oil sprayer installation base.Inner end cap 1, suction tude 2, outlet pipe 10 and body 5 are installed on the cylinder liner 7.Design has cooling liquid outlet 8 and body cooling sap cavity 13 on the body 5.Design has cooling liquid inlet 11 on the suction tude 2.Design has cylinder liner suction port flange 3, cylinder liner relief opening flange 9 on the cylinder liner 7, cooling liquid bath 15,12 relief openings 18,18 spiral stream guidance grooves 16 and 1 oil sprayer installation base 17, the cross section of spiral stream guidance groove 16 is trapezoidal, the pitch of spiral stream guidance groove 16 is 180mm, be provided with 12 apertures 14 between the adjacent relief opening 18, the diameter of aperture 14 is 6mm, oil sprayer installation base 17 is between spiral stream guidance groove 16, and it is shaped as frustoconic shape, and the end face diameter of round platform is 22mm, the bottom surface diameter is 26mm, and height is 9mm.Cylinder liner suction port flange 3 is provided with two cylinder liner O type circles 12.Graphite annulus 4 is installed between the faying surface of outlet pipe 10 and body 5.Body 5 is equipped with O type circle 6 with cooperating of cylinder liner 7 on the cylinder.
The present invention compared with prior art has following beneficial effect: having designed cross section at the middle part of cylinder liner is trapezoidal spiral cooling liquid guiding gutter, and cooling liquid is carried out water conservancy diversion, and cooling liquid flows at cylinder-barrel surface equably, takes away heat; The oil sprayer boss is designed to frustoconic shape, has strengthened the film-cooled heat of oil sprayer, leaves cooling passage around the boss, and cooling liquid flows to the cylinder liner middle part, around the oil sprayer installation base, oil sprayer is cooled off; Have aperture between the relief opening of cylinder liner, cooling liquid arrives after the exhaust ports, flows through from aperture, and the exhaust port area that heat load is serious is cooled off; The relief opening flange exterior edge face design of cylinder liner has the cooling liquid bath, has strengthened cooling sap cavity volume, has reduced the coolant flow resistance, and cooling liquid can evenly be flowed; Can effectively cool off position, firing chamber, piston details, oil sprayer installation base, cylinder liner relief opening, the good cooling results of cylinder of internal-combustion engine has prolonged working life of cylinder, has improved the performance of cylinder.
