Abstract
The utility model relates to a GG-type engine cylinder end cover, comprising a cover body, oil channels inside of the cover body, an oil pipe, an oil nozzle on the oil pipe, seal rings, fixed screw holes for connecting the end cover with the cylinder end and cooling fins arranged on the cover body top, which is characterized in that the end cover fits the joint part of the cylinder end, which is provided with extension part around; cooling fins are spread around the cover body and stiffeners are arranged between fins; and cooling fins are spread on the cover body top. Due to the increased weight of the end cover, the radiating area is increased, the cover end temperature is reduced and the conduction heat transfer performance is better than original. Cooling fins are arranged around the end cover to not only increase the radiating area, but also improve the radiating performance because the flowing air during vehicle moving blows off the heat. Meanwhile, heat exchange through the end cover chamber wall and the wind cooling of the outer cooling fins can further reduce the temperature to avoid the premature deterioration of the engine oil, which extends the service life of the engine.
Description
Technical field
The utility model relates to a kind of engine cylinder skull, specifically a kind of lid of CG h type engine h cylinder head.
Background technique
Can produce a large amount of heats in the engine working process, high temperature can influence engine life.Former CG type air cooling engine is simple in structure, uses easy to maintenancely, and cost is lower, welcome by the masses.But its heat diffusion area is little, causes engine temperature too high, and power performance descends, and the parts premature wear occurs, and machine oil is rotten too early, and radiating effect is undesirable, and is long apart from low speed, obvious especially under the heavy load situation.So people have thought many ways.As, at other oil radiator (being commonly called as the oil cooling machine) or the installation water-filled radiator (being commonly called as water cooling unit) installed of motor.But all there are many defectives in they.Concerning oil radiator has been installed, engine start, oil radiator also during underfill machine oil, press less than in the cylinder head moving element, will cause dry friction as the institution of distributing gas by machine oil, and insufficient lubrication shortens parts life-span.Moreover, can bring dipstick to survey the oil difficulty.Because, the former oil that recorded, and after oil radiator was full of machine oil, the crankcase oils plane descended.Special when vehicle driving up, oily plane and domatic shape in an angle, oil mass under normal circumstances all may make oil pump take out less than machine oil.People were shortened dipstick afterwards, added oil and were remedied, and had then increased engine load and fuel consumption.In addition, the cost of oil radiator system is also very expensive.Concerning water-filled radiator was installed, its expense was expensive especially.And because the boiling point of water is a 100, boiling is expanded the radiator spalling easily, and water outlet emits vapour to cause the scald human body.Water outlet rear engine temperature also can raise.Water-filled radiator uses of a specified duration, and incrustation scale appears in water channel, the heat dispersion variation.In winter, can cause the possibility of the bursting by freezing of freezing if forget the water that bleeds off in the water channel, water tank and machine.The joint of the various radiators that motor is other and connecting tube have also caused at any time and have broken danger, might occur at any time leaking, the leakage of oil problem, make the working life of motor shorter.Have in order to improve cooling effect, enlarge water tank, temp controller be installed, add fan again; Replace water etc. with cooling liquid.This has not only improved cost, and effect is all not really desirable.
Air cooler is also arranged at present, and its cost is lower, but exists heat diffusion area little, the undesirable problem of radiating effect.
Summary of the invention
The purpose of the utility model is to remedy above-mentioned deficiency, and it is low to provide a kind of type with fitting machine oil radiator, water-filled radiator to compare cost to society, the engine cylinder skull of the Wind-cooling type heat radiation of good heat dissipation effect.
The technical solution of the utility model is achieved in that
A kind of CG h type engine h cylinder head cover comprises jet on oil duct in the lid, lid, oil pipe, the oil pipe, seal ring, in order to connect the fixed screw holes of cylinder head cover and cylinder head, the radiating fin at lid top; It is characterized in that cylinder head cover and cylinder head connecting part match, and be provided with epitaxial part (12) around the cylinder head cover in addition; Four sides of lid are covered with between radiating fin, radiating fin establishes stiffening rib.
Described cylinder head cover monnolithic case and cylinder head are coordinated, and be tight with contacting of cylinder head, and wherein the middle part, bi-side respectively is provided with a semi-circular recesses that matches with semi-circular recesses on the cylinder head.Described lid top has been covered with radiating fin.The radiating fin at described lid top is longitudinally or horizontal.The described radiating fin that is covered with lid four sides is horizontal, and is parallel with the radiator of engine cylinder head.Four sides or wherein symmetrical both sides are provided with stiffening rib longitudinally between the horizontal radiating fin of described lid four sides.After the stiffening rib of described lid four side radiating fin is provided with, between recess and the stiffening rib through hole is arranged between two radiating fin.
The utility model has the advantages that: because, being provided with epitaxial part around the cylinder head cover in addition, the cylinder head cover quality increases, and thermal capacity increases, and heat diffusion area increases simultaneously, cylinder head cover temperature step-down, all more original good of heat-conductive characteristic.Again because, cylinder head cover four sides are provided with radiating fin, have not only increased heat diffusion area, and radiating fin is transversely arranged, flow air can be taken away more heats in the vehicle driving process, its heat dispersion improves.In addition, after the cylinder head cover good heat dissipation effect, the motor bulk temperature is decreased.When oil temperature in crankcase reduced, machine oil splashed after by oil duct, the cylinder head cover internal chamber wall transmission of heat and the air-cooled effect of outer radiating fin under reduce oil temperature more, avoided machine oil to go bad too early.Circulation makes engine radiating faster in the machine of subzero engine oil.So benign cycle makes engine life longer.Machine oil is not subjected to high temperature and when having protected oil film, the consumption expense of machine oil also descends thereupon.
