Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cylinder head technology, and relates to a cooling structure, particularly a cylinder head cooling structure. Background Technology
[0002] The cylinder head is one of the core components of an internal combustion engine. Located at the top of the engine, it, together with the cylinder block and piston, forms the combustion chamber and directly affects the engine's performance, reliability, and durability.
[0003] The cylinder head cooling effect in the current market is poor. In order to avoid excessive heat from damaging the engine, the cylinder head is used to cool the engine. Currently, air cooling is usually used, but the cooling efficiency is low and cannot meet the cooling requirements of the cylinder head. Therefore, designing a cylinder head cooling structure is of great significance. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a cylinder head cooling structure.
[0005] The objective of this utility model can be achieved through the following technical solution: a cylinder head cooling structure, characterized in that it includes a cylinder head body, a direct flow channel is provided inside the cylinder head body, a side flow channel one communicating with the direct flow channel is provided inside the cylinder head body, a slow flow channel communicating with the side flow channel one is provided inside the cylinder head body, a second side flow channel two communicating with the slow flow channel and the direct flow channel is provided inside the cylinder head body, and a baffle is provided inside the direct flow channel.
[0006] In the above-mentioned cylinder head cooling structure, an inlet communicating with a DC channel is fixedly provided on one side of the cylinder head body, and an outlet communicating with a DC channel is fixedly provided on the other side of the cylinder head body.
[0007] In the above-mentioned cylinder head cooling structure, a sealing gasket is provided at both the inlet and outlet, and a positioning ball integral with the sealing gasket is provided on one side of the sealing gasket. A groove is provided on the cylinder head body for the positioning ball to engage.
[0008] Compared with existing technologies, this cylinder head cooling structure increases the cooling flow channel and the flow area of the coolant, thereby increasing the cooling area and thus improving the cooling effect of the cylinder head. Attached Figure Description

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0013] like Figures 1-2 As shown, this cylinder head cooling structure includes a cylinder head body 1, a direct flow channel 2 inside the cylinder head body 1, a side flow channel 3 communicating with the direct flow channel 2 inside the cylinder head body 1, a slow flow channel 4 communicating with the side flow channel 3 inside the cylinder head body 1, and a second side flow channel 5 communicating with the slow flow channel 4 and the direct flow channel 2 inside the cylinder head body 1. A baffle 6 is provided inside the direct flow channel 2. By introducing coolant into the direct flow channel 2, the flow of coolant carries away the heat of the cylinder head. When the coolant flows through the direct flow channel 2, the baffle 6 allows the coolant to enter the side flow channel 3, and then the coolant passes through the slow flow channel 4 and the second side flow channel 5 in sequence, increasing the flow area of the coolant and thus increasing the cooling area, thereby improving the cooling effect of the cylinder head.
[0014] Preferably, an inlet 8 connected to the DC channel 2 is fixedly provided on one side of the cylinder head body 1, and an outlet connected to the DC channel 2 is fixedly provided on the other side of the cylinder head body 1.
[0015] Preferably, a sealing gasket 9 is provided at both the inlet 8 and the outlet. A positioning ball 10 integral with the sealing gasket 9 is provided on one side of the sealing gasket 9. A groove 11 for the positioning ball 10 to be engaged is provided on the cylinder head body 1. Both the positioning ball 10 and the sealing gasket 9 are made of rubber material.
[0016] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
