Cylinder head cooling structure
The present invention relates to a cylinder head cooling structure for cooling a cylinder head by using a cooling water, and more particularly, to a cylinder head cooling structure which increases the cooling efficiency of a cylinder head by pressurizing and spraying the cooling water to obtain a high output.
The conventional cylinder head cooling structure forms a basic skeleton of the cylinder head 10 as shown in FIG. 1, and includes an injector (not shown) and a head body 11 having an intake port 12 and an exhaust port 13 formed therein. Is formed in the injector boss 14 into which the head is inserted, the cooling water discharging port 15 formed in the head main body 11 and the cooling water from the cylinder block (not shown), and the port forming portion of the head main body 11. And a plug inserted into the head body 11 to seal the cylinder head 10 after the cooling water injection passage 16 and the cooling water injection passage 16 through which the cooling water eluted into the cooling water discharging opening 15 ( 17).
In the conventional cylinder head cooling structure configured as described above, the cooling water eluted to the cooling water discharging port 15 is sprayed through the cooling water injection passage 16 to cool the cylinder head 10 portion.
Coolant is eluted from the water jacket of the cylinder block (not shown) to the coolant discharging opening 15, and the eluted coolant is moved along the coolant injection passage 16 to move the intake port 12 and the exhaust port 13. Cooled. The coolant moved along the coolant spray passage 15 formed in the port forming portion of the head body 11 is sprayed toward the injector boss 14 at its tip to cool around the injector (not shown).
However, in the conventional cylinder head cooling structure configured as described above, since the pressure of the coolant injected through the coolant injection passage 15 is low, sufficient cooling is not performed at each part of the cylinder head 10, so that the output of the engine is lowered. There is a problem.
That is, the hydraulic pressure of the cooling water supplied to the cylinder head 10 is only the pressing force of the water pump (not shown), and since a part of it is exhausted to the elution pressure, the injection pressure of the cooling water actually injected from the cooling water passage is not so large, and thus, around the injector Insufficient cooling of the parts results in a decrease in engine output.
The present invention has been made to solve the above problems of the prior art, to provide a cylinder head cooling structure that can improve the output of the engine by improving the cooling efficiency by pressurizing and spraying the cooling water flowing through the cylinder head. have.

The present invention forms a basic skeleton of a cylinder head and includes a head body in which an inlet port and an exhaust port are formed, an injector boss into which an injector is inserted, and a coolant injection in which coolant is formed in a port forming part of the head body and injected into the injector boss. A cylinder head cooling structure including a passage, comprising: a cooling water passage formed on one side of the head body and flowing coolant flowing from a cylinder block, a pressurized impeller installed on the cooling water passage, the pressurized impeller and an impeller shaft And a pulley coupled to the crank pulley by a belt to rotate the pressurized impeller, and a bearing installed on the head body to support the impeller shaft.
Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described.
As shown in FIG. 2, the cylinder head cooling structure according to the present invention forms a basic frame of the cylinder head 50 and includes an injector (not shown) and a head main body 51 having an intake port 52 and an exhaust port 53. An injector boss 54 into which the injector boss is inserted, a coolant passage 55 through which a coolant formed on one side 51 of the head body and moved from a cylinder block (not shown) flows, and a port of the head body 51. A cooling water injection passage 56 formed in the forming portion and flowing with the cooling water sprayed toward the injector boss 54 and a head body 51 for hermetically sealing the cylinder head 50 after the cooling water injection passage 56 has been processed. A plug 57 inserted into the plug, an axial impeller 61 installed on the cooling water passage 55, the axial impeller 61 and an impeller shaft 61 ', and a belt to a crank pulley (not shown). Connected to 64 to rotate the axial impeller 61 '. It consists of a pulley (63) and a bearing (62) attached to the head body (51) to support the impeller shaft (61 ').
The cylinder head cooling structure of the present invention configured as described above is moved from the cylinder block (not shown) and the cooling water flowing through the coolant passage 55 is pressurized and injected by the axial flow impeller 61 to cool the cylinder head 50. do.
When the engine is operated, the pulley 63 connected to the crank pulley (not shown) and the belt 64 are rotated, and the axial impeller 61 coupled to the pulley 63 by the impeller shaft 61 'is rotated. The cooling water flowing through the cooling water passage 55 is pressurized. The pressurized coolant moves along the coolant injection passage 56 to cool the intake port 52 and the exhaust port 53, and is sprayed toward the injector boss 54 at the front end thereof to move a portion around the injector (not shown). Cool.
At this time, since the coolant injected through the coolant injection passage 56 is in a pressurized state, the coolant injected into the injector boss 54 is scattered to each part of the cylinder head 50, thereby cooling the cylinder head 50 evenly. . When the high temperature portion of the cylinder head 50 is properly cooled, the efficiency of the engine is increased, resulting in an improvement in output.
As described above, the cylinder head cooling structure according to the present invention pressurizes the cooling water supplied to the cylinder head by using the axial flow impeller, thereby spraying the respective parts of the cylinder head appropriately, so that the output of the engine is improved.
