Abstract
The utility model discloses an air-water dual-cooled cylinder head, including a cylinder head basal body, a combustion chamber and a top cover chamber; first radiating fins are respectively arranged on left and right outer walls of the cylinder head basal body; a water chamber is disposed between the combustion chamber and the top cover chamber in the cylinder head basal body; the water chamber is provided with a first baffle which is lower than the water chamber and divides the water chamber into left and right two parts; the front end of the cylinder head basal body is equipped with left and right front end covers and the back end is equipped with left and right back end covers; and the cylinder main body, left and right front end covers, left and right back end covers and the baffle enclose a circulation water channel around the combustion chamber and the top cover chamber. The utility model has advantages of good water flow circulation effect and high cooling efficiency.
Description
Technical field
The utility model relates to a kind of engine cylinder head, relates in particular to the two cold air cylinder heads in a kind of geomantic omen.
Background technique
All be equiped with incorporate aluminium alloy cylinder head on the engine cylinder-body, the water-cooled engine cylinder head is cooling medium with water, is provided with water cavity, valve in cylinder head, and rocker arm support and rocking arm are equipped with in the top.Motor in the course of the work, cooling water enters in the interior water cavity of cylinder head through cylinder body and circulates, and makes cylinder head obtain cooling, thereby the heat that motor imports cylinder head in working order down into is reduced, to improve the power of motor, reduce engine fuel and consumption of lubricating oil.
The type of cooling of existing motor car engine cylinder head roughly has following several:
1, adopt heat radiation type air-cooled, promptly be on the cylinder head outer wall, to be provided with radiating fin to cool off, these machines are when big load operation, can make that Cylinder Head Temperature is too high, oil lubricating effect variation, thereby wearing and tearing have been strengthened, shortened the working life of cylinder head, 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 cylinder head periphery, around the tripartite of center, firing chamber or be circumferentially with water channel and cool off, three parts in the firing chamber is provided with the situation of water channel owing to have a direction water channel not to be set so cooling effect is poor, be difficult to reach the circulation of water, cooling effect is poor.
The model utility content
Technical problem to be solved in the utility model is to provide the two cold geomantic omens of water, wind that a kind of water circulation is effective, cooling effectiveness is high two cold air cylinder heads.
The technical solution of the utility model is as follows: the two cold air cylinder heads in the geomantic omen of design, comprise the cylinder head matrix, firing chamber and top cover chamber, on the outer wall of the left and right sides of described cylinder head matrix, be equipped with first radiating fin, its main points are: be provided with water cavity between firing chamber in described cylinder head matrix and the top cover chamber, in this water cavity, be provided with first dividing plate that highly is lower than the water cavity height this water cavity is separated into left and right sides two-part, the front end of described cylinder head matrix is equipped with a left side, right front end cap, a left side is equipped with in the rear end, right back end cap, described cylinder head matrix, a left side, right front end cap, a left side, right back end cap and dividing plate surround the circulation water channel around firing chamber and top cover chamber.
The utility model is creatively to design on the basis of traditional cylinder head cooling effect difference, the utility model changes traditional cylinder head and has only air-cooled or deficiency that can only water-cooled, it is two cold to be designed to the geomantic omen, water-cooled water cavity of the present utility model is designed to the water channel that circulates simultaneously, make cooling water enter and flow out inside and outside through the firing chamber of required cooling, cylinder head is carried out omnibearing cooling, because the circulation water channel can cool off the various piece of cylinder head, cooling water flows simultaneously, so good cooling results.
The second partition of described circulation water channel through radially being provided with is divided into the multilayer water channel, and adjacent upper and lower layer water channel communicates, right front place is provided with water intake in described cylinder head matrix lower end surface, be provided with water outlet in the described right rear end portion of covering, above structure makes the circulation water channel become spiralling structure, cooling-water flow also becomes spiral to rise, and so making does not have the dead angle in the circulation water channel, can not cause incrustation scale etc. influence the factor existence of cooling effect.
Be equipped with second radiating fin on described left and right front cover and the left and right rear end cover outer wall, above structure makes that the cooling effect of left and right front cover and left and right rear end cover is better.
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.
