Abstract
The utility model relates to a W-shaped flow structure of a double-layer water jacket for an integral cylinder cover of an engine, and is characterized in that the water jacket for the cylinder covercomprises an upper-layer water jacket and a lower-layer water jacket, between which a transverse partition plate is arranged; main watering holes of the cylinder cover are formed on the lower sides ofexhaust channels; the bottom and the two sides of the exhaust channel are separated through ribs; communication holes for the upper and the lower layers of water jackets are formed on an exhaust side, and auxiliary watering holes are formed on an air inlet side; water flow flows into the water jackets of the cylinder cover from the main watering holes of the cylinder cover, shunts towards the twoends after passing through the area between exhaust channels and flows through the area between the exhaust channels and air inlet channels on the two sides, then retraces and flows to the exhaust side to enter the upper-layer water jacket, and the flowing curve of the main water flow takes the shape of W. The W-shaped flow structure is characterized in that the areas of the cylinder cover needing to intensify cooling can be cooled sufficiently, and the areas such as the air inlet side and top surface of the water jacket are provided with little water, so that the reliability of the cylindercover is improved and the resistance of the whole cooling system is reduced.
Description
Technical field
The utility model belongs to the technical field of motor car engine, particularly a kind of motor overall cylinder cover double-layer water jacket " W " type fluidal texture.
Background technique
At present, in the design of traditional cylinder head, water jacket is the water cavity that the internal surface by the outer surface of intake and exhaust port and cylinder head profile forms naturally, and cooling water enters cylinder head and easily flows at the top, and the cylinder head bottom is need the reinforcement cooled zones.Therefore the current that form are difficult to flow according to predetermined mode.Cylinder head jacket sticks together the two-tiered water jacket core during part casting because the requirement of technology generally is a median plane with air flue is divided into two-layerly, has just formed uncontrollable overlap like this in the middle of two-tiered water jacket, has improved reject rate.
The cooling of cylinder head is not only by the contradiction at base plate and top, and requires also inequality to the cooling of air inlet side and exhaust side.Though because the contact of the bottom of cylinder head be high-temperature fuel gas, fresh air temperature mobile in intake duct is lower, it has cooling action to whole air inlet side.And the waste gas that flows in air outlet flue also has the further effect of heating to exhaust side, and the heat load that therefore reduces exhaust side is only the key that improves the cylinder head reliability.
Summary of the invention
The utility model purpose provides a kind of motor overall cylinder cover double-layer water jacket " W " type fluidal texture.
The technical solution of the utility model is achieved in that
Motor overall cylinder cover double-layer water jacket " W " type fluidal texture, it is characterized by: cylinder head jacket is made up of upper strata water jacket and lower floor's water jacket, in the middle of upper strata water jacket and the lower floor's water jacket diaphragm is arranged, cylinder head Your Majesty opens in the water hole at the air outlet flue downside, air outlet flue bottom surface and both sides separate with muscle, water jacket upper strata and water jacket lower floor have intercommunicating pore at exhaust side, the air inlet side has the auxiliary water hole of going up, current flow into cylinder head jacket by cylinder head Your Majesty water hole, divide to two ends through back between air outlet flue and the air outlet flue, flow through the respectively air outlet flue of both sides and the zone between the intake duct, current are turned back and are flowed to exhaust side and enter the upper strata water jacket afterwards, and the flow curve of main current is " W " type.
The characteristics of motor overall cylinder cover double-layer water jacket " W " type fluidal texture be need strengthen cooled zones to cylinder head can both be abundant, only provide small amount of water for zones such as water jacket air inlet side and end faces, the reliability that has so not only improved cylinder head can also reduce the resistance of whole cooling system.

Fig. 2 is a cross-sectional view of the present utility model.
Fig. 3 is the mobile schematic representation of the utility model " W " type water.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Motor overall cylinder cover double-layer water jacket " W " type fluidal texture, it is characterized by: cylinder head jacket is made up of upper strata water jacket 1 and lower floor's water jacket 2, in the middle of upper strata water jacket 1 and the lower floor's water jacket 2 diaphragm 3 is arranged, 4 designs of cylinder head Your Majesty water hole are at the air outlet flue downside, air outlet flue bottom surface and its both sides separate with muscle 7, water jacket upper strata 1 and water jacket lower floor 2 have intercommunicating pore 6 at exhaust side, the air inlet side has the auxiliary water hole 5 of going up, current flow into cylinder head jacket by cylinder head Your Majesty water hole 4, divide to two ends through 9 backs, zone between air outlet flue and the air outlet flue, the zone 10 between the air outlet flue of both sides and the intake duct of flowing through respectively, current are turned back and are flowed to exhaust side and enter upper strata water jacket 1 afterwards, and the flow curve of main current is " W " type.
Embodiment:
Adopt double-deck control as Fig. 1, Fig. 2 and the utility model cylinder head water flow inside shown in Figure 3 control, cylinder head jacket is made up of upper strata water jacket 1 and lower floor's water jacket 2, in the middle of upper strata water jacket 1 and the lower floor's water jacket 2 diaphragm 3 is arranged, upper strata water jacket 1, lower floor's water jacket 2 flow respectively and do not disturb mutually; Lower floor's water jacket 2 is controlled in the limited space 8, and its water velocity guarantees easily, can strengthen the cooling to the cylinder head base plate; Help the realization of cylinder head current control strategy like this, reduce the cylinder head heat load intensity, improve the firm life-span of cylinder cap; The middle diaphragm 3 of water jacket has replaced original uncontrollable overlap, and by drawing control, diaphragm 3 can increase cylinder head rigidity to the shaped position of diaphragm 3 simultaneously, has improved cylinder head mechanical load intensity fully; Your Majesty water hole 4 can solve the contradiction of air inlet side and exhaust side cooling at the cylinder head exhaust side; At first water jacket being divided into upper strata water jacket 1 and lower floor's water jacket 2, also is the prerequisite of tissue " W " type current; 4 designs of cylinder head Your Majesty water hole are at the air outlet flue downside, air outlet flue bottom surface and both sides are separated with muscle 7, cooling liquid forms an enclosed areas 8 below air outlet flue, make current through zone 9 between air outlet flue and the air outlet flue, such design has at first guaranteed the cooling in the zone of cylinder head heat load maximum; Secondly zone 10 also is to strengthen cooled zones between intake duct and air outlet flue, so current are organized zone 10 between the air outlet flue of its both sides of flowing through respectively and the intake duct after flowing out through zone between air outlet flue and the air outlet flue 9; Upper strata water jacket 1, lower floor's water jacket 2 are communicated with at exhaust side, and promptly upper water submantle layer water jacket attachment hole 6, and current are turned back and flowed to exhaust side and enter upper strata water jacket 1 afterwards, and the flow curve of main current is " W " type of English alphabet; Need increase in the air inlet side in addition and assist water hole 5, the current of small number of drive air inlet side get final product, and are less to whole current notion influence.
