Description

The two cold engine cylinder bodies of spiral circulation water channel

Technical field

The utility model relates to a kind of engine cylinder-body, especially a kind of two cold engine cylinder bodies of water, wind that are provided with spiral circulation water channel.

Background technique

The type of cooling of existing motor car engine cylinder body roughly has following several:

1, adopt heat radiation type air-cooled, promptly be on the engine cylinder-body outer wall, to be provided with radiating fin to cool off, these machines are when big load operation, can make that engine block temperature is too high, oil lubricating effect variation, thereby the wearing and tearing of piston and cylinder wall have been strengthened, shortened the working life of cylinder body, even the cylinder phenomenon that rises because of engine temperature is too high that has;

2, adopt water-cooled, promptly there is not the situation of radiating fin to exist in the engine block periphery, around the tripartite of center, cylinder hole or be circumferentially with water channel and cool off, the three parts in the cylinder hole is provided with the situation of water channel owing to have a direction water channel not to be set so cooling effect is poor, is difficult to reach the circulation of water; Though and the cylinder hole circumferentially be provided with water channel can make water can in water channel, obtain the circulation, cooling effect is also better, but because the water intake of its water channel is lower than water outlet, needs during cooling water to be full of the circulation that water channel just can reach water, therefore occur ponding easily, cooling effect is poor.

3, adopt air-cooled and water-cooled simultaneously, the defective of easy ponding in water channel when also there is the employing water-cooled in this kind situation.

The model utility content

Technical problem to be solved in the utility model is to provide the two cold spiral circulation water channels of water, wind that a kind of water circulation is effective, cooling effectiveness is high two cold engine cylinder bodies.

The technical solution of the utility model is as follows: design the two cold engine cylinder bodies of a kind of spiral circulation water channel, comprise main body cylinder block, radiating fin, cylinder hole; rocking arm mounting hole and hoop water channel; be equipped with radiating fin on the outer wall of the left and right sides of main body cylinder block; its main points are: the front end at this main body cylinder block is equipped with front cover; rear end cover is equipped with in the rear end; described main body cylinder block; it is the hoop water channel at center that front cover and rear end cover surround with cylinder hole and rocking arm mounting hole; described hoop water channel is divided into the multilayer water channel through dividing plate; be positioned on described main body cylinder block front portion adjacent; lower floor's water channel communicates; the place is provided with water intake at described front cover lower base water channel, on a described main body cylinder block left side or water channel place, top, right side wall top be provided with water outlet.Establish radiating fin on the left and right sides outer wall of the utility model with main body cylinder block and be the hoop water channel that the center is provided with completely encircle with cylinder hole and rocking arm mounting hole, can make extraneous air cooling and water cooling bring into play effect simultaneously, especially be provided with multilayer hoop water channel, allow the water that injects from water pump when water intake enters, along the hoop water channel, spiral mobile freely the promotion flowed to water outlet, thoroughly solved the situation of in the past cooling off hot water and cold water mixed and alternate in the main body cylinder block water channel, allow circulating water by first water intake, be center ring to the water channel multi-turn that circulates around cylinder hole and rocking arm mounting hole successively then, discharge along water outlet again, like this, accelerated flowing of water, promptly taken away the heat in the engine cylinder-body, reached purpose to the motor cooling.

Above-mentioned hoop water channel is divided into superposed top water channel and is positioned at the bottom water channel of bottom, it is better that 2 layers of hoop water channel effect are set, both can reach good cooling effect, and can make water unresisted flowing in the hoop water channel again, thereby avoid the narrower water blocking that causes of hoop water channel.

Be equipped with radiating fin on described front cover and the rear end cover outer surface, so cooling effect is better.

Described water intake is positioned at the lower left corner of described front cover, and described water outlet is positioned at the upper left corner of described main body cylinder block right side wall, and so setting can not cause in the hoop water channel and ponding occur, and the water that is injected is circulation successively all.

Beneficial effect: 1. good cooling results; 2. ponding can not occur in the cooling water channel, cooling water is well circulated; 3. simple and practical.
