Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the better embodiment of the utility model cylinder head cooling structure includes the cylinder with combustion chamber
Head body 1, the cylinder head body 1 provided with inlet channel 2, exhaust passage 3 and is surrounded by fin in cylinder head body 1.
Be provided with the first cooling duct run through and the second cooling duct run through in the cylinder head body 1, first cooling duct with
Second cooling duct is connected.First cooling duct is located above combustion chamber, and cooling is sufficiently used for ensure that combustion chamber has
Air passes through.Second cooling duct fitted with the outer wall of inlet channel 2 and the outer wall of exhaust passage 3 with cool down inlet channel 2 and
Exhaust passage 3, ensures the cooling of inlet channel 2 and exhaust passage 3, while wrapping up combustion chamber.Spark-plug hole 4 is located at the first cold wind
The first end in road, the second end of first cooling air channel 5 is provided with the 3rd cooling air channel 7, the 3rd cooling air channel 7 perpendicular to
First cooling air channel 5, the 3rd cooling air channel 7 guiding cold air flows to engine cylinder-body, further wraps up combustion chamber,
Reduce the temperature of combustion chamber.
The surrounding of the inwall of first cooling air channel 5 is equipped with the guide vane 51 located at guiding air flow, increases air
The area of flowing, reduces blind area.In other embodiments, also can only wherein one side or several times set guide vane 51.
Second cooling air channel includes inlet gas cooling passage 61 and exhaust cooling duct 62, the inlet gas cooling passage 61
It is located at the both sides of the first cooling air channel 5 with exhaust cooling duct 62.Because by the axis of the inlet channel 2 and exhaust passage 3
Axis is in the same plane, therefore is effectively reduced the bending of inlet gas cooling passage 61 and exhaust cooling duct 62, improves
The mobility of air, it is to avoid high temperature air is retained on cylinder head body 1 for a long time, while also helping technique manufacture.
When the flywheel on engine rotates with crankshaft high-speed, substantial amounts of wind is produced, wind can enter from the first cooling air channel 5
Enter and discharge, and be diverted to the second cooling air channel and the 3rd cooling air channel 7 is then discharged out, the air of flowing by combustion chamber wrap up into
Row cooling, is easy to combustion chamber quick heat radiating.Second cooling air channel is also fitted the outer wall of inlet channel 2 and the outer wall of exhaust passage 3,
Inlet channel 2 and exhaust passage 3 are cooled down, cooling effect is further improved.Enter cylinder body 8 after the discharge of 3rd cooling air channel 7
