Abstract
Disclosed is a minor sized water-cooled engine cooler which comprises a pump with an admitting pipe and an exhaust pipe, a hydro-cooling tank connecting with the admitting pipe of the pump, a cylinder whereof the intake connecting with the exhaust pipe of the pump, and ring water channels around the cylinder burner. The utility model is characterized in that the outlet of the ring water channel with damping holes is on the cover of the cylinder, matching water channel through holes are installed between the cylinder and its cover for connecting the water channels of the cylinder and the cover, screws are installed on the cylinder water channel through holes for sealing and fixing the cylinder and the cover. The damping holes at the outlet enable the cooling water to circulate better in the cooling water channels for taking away more heat energies and decreasing the temperature of the engine cylinder. The utility model has a compact structure and a reliable operation.
Description
Technical field:
The utility model relates to technical field of engines, particularly a kind of cooling structure of small-sized water cooled engine.
Background technique:
At present, water cooled engine is widely used.As Chinese patent No. 03234485.6 a kind of water-cooled engine cylinder body is disclosed just, this technological scheme is provided with the water channel inlet in the bottom of cylinder block, the cylinder face of cylinder head is provided with the water channel outlet, be distributed with water channel around the cylinder hole, the bottom that cylinder block is provided with the core-drawing hole cylinder block is provided with the husky hole that discharges water.Cooling liquid enters water channel from the water inlet road junction can take away a large amount of heats, to reduce the temperature of engine cylinder-body.This kind structure is applicable to the motor of air displacement more than 125CC.Small-sized water cooled engine adopts said structure can increase volume, and structure is not compact.Therefore, small-sized water cooled engine can't adopt said structure.
Summary of the invention:
The purpose of this utility model is: provide that a kind of structure is tight, the cooling structure of the small-sized water cooled engine of reliable operation.The utility model is achieved through the following technical solutions:
A kind of cooling structure of small-sized water cooled engine, the intake pipe of water pump links to each other with cooling water tank, and the outlet pipe of water pump links to each other with the water intake of cylinder, is provided with water annulus around the firing chamber of cylinder; It is characterized in that: the water outlet of described water annulus is located on the cylinder head, the water outlet place is provided with damping hole, be provided with the water channel through hole that matches between cylinder and cylinder head, the water channel through hole is communicated with cylinder with water channel between cylinder head, be provided with the screw of cylinder and cylinder head sealing and fixing between cylinder water-supply line through hole.Because the water outlet place is provided with damping hole, can make cooling water better circulation in cooling water channel, take away more heat, reduce the temperature of engine cylinder-body.Owing to be provided with the screw of cylinder and cylinder head sealing and fixing between cylinder water-supply line through hole, it can make and adopt the sealing of steel pad between cylinder and cylinder head, makes that sealing reliably prevents leaking, leaking gas of water channel and air flue between the cylinder head of small-sized water cooled engine and cylinder head.The compact structure of the cooling structure of small-sized water cooled engine of the present utility model, reliable operation.
In the utility model, be provided with water annulus in the described cylinder head.It can make the cooling effect of small-sized water cooled engine better.
In the utility model, the water outlet of described water annulus links to each other with cooling water tank.The route of flowing through of cooling water of the present utility model is: cooling water through the cooling waterpump supercharging, enters the cylinder water inlet from the water tank osculum, and cooling water enters cooling water tank from the water outlet of cylinder head, finishes a work cycle.

Fig. 3 is the small-sized water cooled engine cylinder of a utility model generalized section.
Fig. 4 is the outside schematic representation of the small-sized water cooled engine cylinder head of the utility model.
Fig. 5 is the A-A generalized section of Fig. 4.
Embodiment:
In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5: the cooling structure of the small-sized water cooled engine of present embodiment comprises: the intake pipe 2 of water pump 1 links to each other with cooling water tank 3, the outlet pipe 4 of water pump 1 links to each other with the water intake 6 of cylinder 5, is provided with water annulus 7 around the firing chamber of cylinder.The water outlet 8 of water annulus is located on the cylinder head 9, the water outlet place is provided with damping hole 10, cylinder 5 is provided with the water channel through hole 11 that matches with 9 of cylinder heads, water channel through hole 11 is communicated with cylinder with water channel between cylinder head, be provided with the screw 12 of cylinder and cylinder head sealing and fixing between cylinder water-supply line through hole.Be provided with water annulus 13 in the cylinder head.The water outlet 8 of water annulus links to each other with cooling water tank 3.
The route of flowing through of the cooling water of present embodiment is: cooling water through the cooling waterpump supercharging, enters the cylinder water inlet from the water tank osculum, and cooling water enters cooling water tank from the water outlet of cylinder head, finishes a work cycle.
Because the water outlet place of present embodiment is provided with damping hole, can make cooling water better circulation in cooling water channel, take away more heat, reduce the temperature of engine cylinder-body.And the screw on the cylinder, it can make and adopt the sealing of steel pad between cylinder and cylinder head, prevents leaking, leaking gas of water channel and air flue.
