Description
Technical field
The utility model relates to a kind of engine cylinder head, relates in particular to a kind of wind, water cooled engine cylinder head.
Background technique
Motorcycle engine can produce a lot of heats when work, the temperature of motor is raise.Too high temperature not only can make efficiency of engine reduce, and causes the damage of each component on the motor easily, and rate of fault height, working life lack.
Cylinder head needs thermal diffusivity preferably as a vitals on the motor, if the heat radiation of cylinder head is bad, temperature will be very high.Under the hot environment, the yielding even fracture of valve stem makes valve collar, valve oil seal and air valve seat ring etc. impaired, and produces abnormal sound.Generally about 280 degree, if the thermal diffusivity of cylinder head is relatively poor, its temperature can cause valve spring to lose efficacy up to 500 degree to the normal operating temperature of valve spring, and the motor inlet and outlet are obstructed, and output power descends, and has influenced the proper functioning of motor.
Operated by rotary motion has radiating fin on the available engine cylinder head, and purpose is the heat radiation that strengthens cylinder head by air-cooled, to reduce the temperature of cylinder head.But because the air-cooled heat of taking away is very limited, cooling effect is not desirable, and the temperature of cylinder head still can be very high.Certainly, what also have installs cooling water channel at a said cylinder sidewall, makes cylinder head in by air cooling, also can be by water cooling.But because the length of cooling water channel is very short, cooling water can only be taken away the seldom heat of a part of cylinder head, and the cooling effect of countercylinder head is still very poor.
Summary of the invention
The purpose of this utility model just provides wind, the water cooled engine cylinder head of the low and long service life of a kind of rate of fault, and it can carry out air-cooled and water-cooled simultaneously, and thermal diffusivity is good, can guarantee effective output of engine power, makes the work of motor more reliable.
The purpose of this utility model is to realize by such technological scheme, it comprises the cylinder head housing, the cylinder head housing is provided with radiating fin, it is characterized in that: the sidewall of cylinder head housing is sealed with at least one L-shaped cooling water chamber, and the cylinder head housing is provided with at least two water channels excessively that are connected with cooling water chamber.
Cooling water chamber of the present utility model surrounds a circulating water cavity by the cooling water chamber of crossing on water channel and the cylinder block, the water channel of crossing on this water circulation channel and water tank, water pump and/or the cylinder head is communicated with, constitute water circulator, cooling water flow in the water circulator is through cylinder head, to realize the cooling of countercylinder head, i.e. water-cooled.Like this, together with the radiating fin on the cylinder head, on cylinder head, realized air-cooled and water-cooled simultaneously, good cooling results, the temperature of cylinder head is low, can prevent that effectively related components is damaged by high temperature on the cylinder head, low, the long service life of rate of fault, inlet and outlet simultaneously unobstructed can guarantee effective output of engine power.
Owing to adopted technique scheme, the utlity model has the advantage of the low long service life of rate of fault, it can carry out air-cooled and water-cooled simultaneously, and thermal diffusivity is good, and the temperature of cylinder head housing is low, can effectively ensure the normal output of engine power, and it is very reliable to work.
