Description

Wind, water cooled engine cylinder head

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, rate of fault height easily.

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, also can produce abnormal sound.Simultaneously, 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 cooling air only acts on the outer wall of cylinder head, the heat of taking away is very limited, and cooling effect is poor, 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 the low wind of a kind of rate of fault, water cooled engine cylinder head, and it can carry out air cooling and water cooling simultaneously to the cylinder head housing, and thermal diffusivity is good, and the temperature of cylinder head is low, long service life.

The purpose of this utility model is to realize by such technological scheme, it comprises the cylinder head housing, cylinder head housing 1 is provided with radiating fin, pilot hole and inlet and outlet passage, it is characterized in that: be provided with cooling water chamber in the cylinder head housing, the cylinder head housing is provided with two water channels excessively that are connected with cooling water chamber.

Cooling water chamber of the present utility model is arranged on the inside of cylinder head housing, it can surround a circulating water cavity by cooling water chamber or the cooling water channel 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, the cooling water chamber of cooling water flow in the water circulator in the cylinder head housing, the countercylinder head carries out water-cooled.Like this, together with the radiating fin on the cylinder head housing, on cylinder block, 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 are unobstructed, can guarantee effective output of engine power.

Owing to adopted technique scheme, the utlity model has the low advantage of rate of fault, cooling water can directly enter and by the cylinder head enclosure interior, the cylinder head housing is carried out water cooling, and after the air cooling effect of radiating fin combined, the radiating effect of cylinder head housing significantly improved, the temperature of cylinder head is low, long service life, and guarantee that motor has good power performance, make the work of motor more reliable.
