Abstract
The utility model discloses a water cooling double-cylinder engine cylinder head, comprising an air inlet duct, an air outlet duct, a connecting bolt hole, a water inlet of water jacket and a water outlet of water jacket, wherein the water outlet is arranged on the side which is close to the air outlet duct; the surface of the cylinder head is provided with reinforcing and heat dissipation bars. The utility model has the advantages of low noise and environmental protection, and can enhance the total cooling efficiency by more than 10 percent, improve the condition of the engine, increase the efficiency, prolong the service life and improve the sealing reliability of the connection between the cylinder head and the cylinder body; moreover, because the total area of the cylinder head is increased by more than 5 percent, the heat dissipation area is enlarged and the intensity of the cylinder head is increased.
Description
(1) technical field
The utility model relates to a kind of water-cooled twin cylinder engine cylinder head.
(2) background technique:
Existing water-cooled cylinder head, its osculum are arranged near intake duct one side; But engine exhaust road one side temperature is higher, through actual measurement: the air outlet flue one side surface temperature of twin-tub water cooled engine can reach 180 ℃ to 210 ℃, and intake duct one side surface temperature only is 60 ℃ to 90 ℃, so this kind arrangement does not reach best cooling heat dissipation effect.And the area of cylinder head and cylinder junction surface is less, and 8 A, B connecting bolt pitch-row are from nearer, and its assembling connects has adverse effect to cylinder head water cavity water inlet sealing reliability.
(3) model utility content
At the deficiency of prior art, the utility model provides a kind of novel water-cooled twin cylinder engine cylinder head, and the water outlet design of this cylinder head is in higher air outlet flue one side of temperature.
Its technological scheme is: a kind of water-cooled twin cylinder engine cylinder head, comprise intake duct, and air outlet flue, the connecting bolt hole, water cavity water intake, water cavity water outlet, described water outlet are positioned near air outlet flue one side.On the surface of cylinder head the reinforcement radiating fin is arranged.
The utility model near air outlet flue one side, with the corresponding suitable amplification with casing joint face of cylinder head, increases rib with the design of cylinder head water cavity osculum on cylinder head and cylinder cap.Corresponding with this technological scheme, other fit dimension is also answered corresponding change; As: 8 A, B bolt hole distance that cylinder head is connected with cylinder body suitably become big, with the shape and the corresponding change of processing dimension of cylinder head inner assembly camshaft support, with the corresponding change of water cavity shape.
Cylinder head of the present utility model can not change under other conditions, improves total cooling effectiveness more than 10% than existing water-cooled twin-tub product, reduces noise, and is environmental, improves engine operating condition, raises the efficiency, and increases the service life; Can increase cylinder head and casing joint face sealing reliability, increase the cylinder head total surface area more than 5%, just increase heat diffusion area, increase cylinder head intensity because of strengthening radiating fin.

(5) embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
Referring to accompanying drawing 1, Fig. 2 and Fig. 3, a kind of water-cooled twin cylinder engine cylinder head 6 comprises intake duct 1, air outlet flue 2, and connecting bolt hole 3, water cavity water intake 4, water cavity water outlet 5, water cavity water outlet 5 are positioned near air outlet flue 2 one sides.The radiating fin 7 of reinforcement is arranged on the surface of cylinder head 6.
Claims (2)
1, a kind of water-cooled twin cylinder engine cylinder head comprises intake duct (1), air outlet flue (2), connecting bolt hole (3), water intake (4) and water outlet (5) is characterized in that: described water outlet (5) is positioned near air outlet flue (2) one sides.
2, water-cooled twin cylinder engine cylinder head according to claim 1 is characterized in that: on the surface of cylinder head (6) reinforcement radiating fin (7) is arranged.
