[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0034] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0035] Unless otherwise specified, the front-to-back direction in this application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0036] First of all, it should be noted that the traditional cylinder head is also provided with a cylinder head water jacket to cool the cylinder head, but the traditional cooling system mostly adopts the method of cooling the cylinder body first, and then adding water from the cylinder body, and cooling the cylinder head through the cylinder gasket. Such a flow transmission path causes the temperature of the cooling water flowing to the cylinder head to increase, and the heat exchange effect with the cylinder head becomes worse, thereby resulting in reduced cooling effect efficiency, which can easily cause the thermal load of the cylinder head to increase, and in severe cases, a series of faults such as cracking may occur.

[0037] The utility model proposes a cylinder head water jacket 100, which can directly cool the cylinder head so that different parts of the cylinder head can be fully cooled, thereby improving the cooling effect of the cylinder head, effectively reducing the heat load of the cylinder head, and effectively preventing the cylinder head from cracking.

[0038] like Figure 1-Figure 4 As shown, a cylinder head water jacket 100 according to an embodiment of the present invention has a first side water jacket area 1 and a second side water jacket area 2 .

[0039] The cylinder head water jacket 100 has a first side water jacket area 1 and a second side water jacket area 2 . The first side water jacket area 1 is connected to the second side water jacket area 2 and is at least partially spaced apart from each other to define a spark plug avoidance hole 51 .

[0040] Specifically, the first side water jacket area 1 and the second side water jacket area 2 are both used for cooling water circulation to remove heat from the cylinder head, thereby reducing the temperature of the cylinder head. Figure 1 As shown, the first side water jacket area 1 is the water jacket area on the left, and the second side water jacket area 2 is the water jacket area on the right. The first side water jacket area 1 is connected to the second side water jacket area 2, and at least a portion of the middle portion is separated by a certain distance to define a spark plug avoidance hole 51. The spark plug avoidance hole 51 is used to avoid the spark plug to ensure that the spark plug can be safely installed on the cylinder head without contacting the cold water in the water jacket, thereby preventing the spark plug from failing due to water immersion and ensuring that the spark plug can work normally and ignite the mixture.

[0041] The first side water jacket area 1 is provided with a first water inlet 11 and a water outlet 12, and the second side water jacket area 2 is provided with a second water inlet 21. A part of the cooling water entering the first water inlet 11 is suitable for flowing from the first side water jacket area 1 to the water outlet 12, and another part of the cooling water entering the first water inlet 11 is suitable for being diverted to the second side water jacket area 2 and flowing to the water outlet 12 together with the cooling water entering the second water inlet 21.

[0042] That is to say, the cooling water introduced into the cylinder head water jacket 100 from the first water inlet 11 is divided into two parts, one part flows directly to the water outlet 12, and the other part is diverted to the second side water jacket area 2. At the same time, the second water inlet 21 also introduces cooling water into the cylinder head, and after merging with the diverted cooling water, they flow together to the water outlet 12. In this way, different parts of the cylinder head can be fully cooled, thereby improving the cooling effect of the cylinder head, effectively reducing the thermal load of the cylinder head, and avoiding cracking of the cylinder head.

[0043] According to the cylinder head water jacket 100 of the embodiment of the present invention, by arranging the first water inlet 11 and the water outlet 12 in the first side water jacket area 1 and the second water inlet 21 in the second side water jacket area 2, the cooling water is diverted, so that different parts of the cylinder head can be fully cooled, thereby improving the cooling effect of the cylinder head, effectively reducing the heat load of the cylinder head, and effectively avoiding cracking of the cylinder head.

[0044] In some embodiments, the cylinder head water jacket 100 includes a first water jacket portion 3 and a second water jacket portion 4 , each of which is partially located in the first side water jacket area 1 and partially located in the second side water jacket area 2 .

[0045] Specifically, if Figure 2 As shown, the cylinder head water jacket 100 includes a first layer water jacket portion 3 and a second layer water jacket portion 4. Figure 2 As shown in the upper and lower directions, the first layer of the water jacket 3 is located at the top, and the second layer of the water jacket 4 is located at the bottom. Figure 1 As shown in the left-right direction, the left parts of the first water jacket portion 3 and the second water jacket portion 4 are located in the first side water jacket area 1 , and the right parts are located in the second side water jacket area 2 .

[0046] Furthermore, the first layer water jacket portion 3 is connected to the second layer water jacket portion 4 and is at least partially spaced apart and distributed in the up and down directions. The cooling water in the second side water jacket area 2 is suitable for being diverted to the first layer water jacket portion 3 and the second layer water jacket portion 4 to flow to the water outlet 12 respectively.

[0047] like Figure 2As shown, the first water jacket portion 3 is connected to the second water jacket portion 4, so that the cooling water in the first water jacket portion 3 and the cooling water in the second water jacket portion 4 can circulate with each other. For example, the cooling water in the first water jacket portion 3 can flow to the second water jacket portion 4, or the cooling water in the second water jacket portion 4 can flow to the first water jacket portion 3. The rear portions of the first water jacket portion 3 and the second water jacket portion 4 are spaced apart a certain distance in the vertical direction. In this way, the first water jacket portion 3 and the second water jacket portion 4 overlap in the vertical direction, which can more effectively utilize the cooling water for cooling, enhance the cooling effect, and ensure that different parts of the cylinder head are fully cooled.

[0048] The cooling water in the second side water jacket area 2 is suitable for being diverted to the first layer water jacket portion 3 and the second layer water jacket portion 4 to flow to the water outlet 12 respectively, that is, the cooling water flowing into the second side water jacket area 2 through the second water inlet 21 can be diverted to the first layer water jacket portion 3 and the second layer water jacket portion 4 to fully cool the areas of the first layer water jacket portion 3 and the second layer water jacket portion 4 corresponding to the cylinder head, and then, the water after cooling the first layer water jacket portion 3 and the second layer water jacket portion 4 flows to the water outlet 12 respectively and flows out from the water outlet 12.

[0049] Therefore, by setting up two layers of water jacket, the utilization rate of cooling water can be greatly improved, so that the cooling water can be more evenly distributed in the cylinder head, thereby improving the cooling efficiency and cooling uniformity. The two layers of water jacket can also improve the strength of the cylinder head to a certain extent and extend the service life of the cylinder head.

[0050] In actual design, the first layer water jacket portion 3 and the second layer water jacket portion 4 can be configured to be manufactured in an integrated manner, thereby reducing casting costs, simplifying the manufacturing process, and improving the overall structural strength of the cylinder head water jacket 100.

[0051] In some embodiments, the first layer of the water jacket portion 3 is provided with first layer exhaust holes 31 in both the portion located in the first side water jacket area 1 and the portion located in the second side water jacket area 2 .

[0052] Specifically, if Figure 1 As shown, the first layer water jacket portion 3 located in the first side water jacket area 1, i.e., the left side portion, and the first layer water jacket portion located in the second side water jacket area 2, i.e., the right side portion are both provided with first layer exhaust holes 31. That is to say, there are two first layer exhaust holes 31 provided on the first layer water jacket portion 3. The provision of the first layer exhaust holes 31 is conducive to accelerating the flow of cooling water in the first layer water jacket portion 3, thereby more effectively taking away the heat from the cylinder head. The first layer exhaust holes 31 can form a more complex cooling water flow path on the first layer water jacket portion 3, thereby improving the heat exchange efficiency and making the cooling water distribution more even. It can also serve as an additional heat dissipation channel to help reduce the overall temperature of the cylinder head.

[0053] In other embodiments, the second layer of the water jacket portion 4 is provided with second layer exhaust holes 41 in both the portion located in the first side water jacket area 1 and the portion located in the second side water jacket area 2 .

[0054] Specifically, if Figure 4 As shown, the second-layer water jacket portion 4 located in the first side water jacket area 1, i.e., the left side portion, and the second-layer water jacket portion located in the second side water jacket area 2, i.e., the right side portion are both provided with second-layer exhaust holes 41. That is to say, there are two second-layer exhaust holes 41 provided on the second-layer water jacket portion 4, and the two second-layer exhaust holes 41 are arranged in a one-to-one correspondence with the two first-layer exhaust holes 31 in the up and down directions. The setting of the second-layer exhaust holes 41 is conducive to accelerating the flow of cooling water in the second-layer water jacket portion 4, thereby more effectively taking away the heat from the cylinder head, and the second-layer exhaust holes 41 can form a more complex cooling water flow path on the second-layer water jacket portion 4, thereby improving the heat exchange efficiency and making the cooling water distribution more even. It can also serve as an additional heat dissipation channel to help reduce the overall temperature of the cylinder head.

[0055] Therefore, through the corresponding arrangement of the first layer exhaust holes 31 and the second layer exhaust holes 41, the cooling efficiency of the cylinder head is greatly improved, the heat dissipation capacity and the cooling uniformity are enhanced, thereby further increasing the cooling effect on the cylinder head and helping to improve the cooling performance of the engine.

[0056] In some embodiments, as Figure 2 As shown, the water outlet 12 is communicated with the second water jacket portion 4 , that is, the cooling water after heat exchange in the second water jacket portion 4 can flow toward the water outlet 12 and flow out from the water outlet 12 .

[0057] The second layer water jacket portion 4 is provided with a first spoiler cutout 42 in the nose bridge area 52 between the two second layer exhaust holes 41 , and / or the second layer water jacket portion 4 is provided with a second spoiler cutout 43 in the portion located in the first side water jacket area 1 .

[0058] Specifically, if Figure 4 As shown, the second-layer water jacket portion 4 is provided with a first spoiler cutout 42 in the nose bridge area 52 between the two second-layer exhaust holes 41. The first spoiler cutout 42 is constructed as a circular cutout. The first spoiler cutout 42 is used to guide the cooling water to the vicinity of the second-layer exhaust holes 41, thereby enhancing the cooling effect around the second-layer exhaust holes 41, and also promoting the cooling of the nose bridge area 52.

[0059] The second layer water jacket portion 4 is provided with two second spoiler cutouts 43 in the portion located in the first side water jacket area 1 . The second spoiler cutouts 43 are used to spoil the flow and guide part of the cooling water of the second layer water jacket portion 4 to flow toward the nose bridge area 52 to fully cool the nose bridge area 52 .

[0060] In practice, the second spoiler cutout 43 located above the second-layer exhaust hole 41 can also reduce the cooling water flow rate in the second-layer water jacket 4, and cooperate with the second spoiler cutout 43 to guide the cooling water to flow toward the bridge of nose area 52, thereby increasing the cooling water flow rate in the bridge of nose area 52 and improving the cooling effect on the bridge of nose area 52. After heat exchange in the bridge of nose area 52, the cooling water can continue to flow toward the water outlet 12 and flow out from the water outlet 12.

[0061] In some embodiments, the first side water jacket area 1 is provided with a plurality of first side cutouts 13, that is, two, three, four or even more first side cutouts 13 are provided in the first side water jacket area 1. The provision of a plurality of first side cutouts 13 can guide the cooling water in the first side water jacket area 1 at multiple positions, thereby facilitating the diversion of the cooling water to various places, and can better cool the cylinder head area corresponding to the first side water jacket area 1, thereby improving the cooling effect of the cylinder head.

[0062] Multiple first side cutouts 13 are spaced apart in the first side water jacket area 1 along the flow direction of the cooling water, that is, the multiple first side cutouts 13 can disturb the cooling water along the flow direction of the cooling water, guide part of the cooling water to flow to the water outlet 12, and the other part of the cooling water to flow to the second side water jacket area 2. At the same time, the multiple first side cutouts 13 spaced apart can ensure that the cooling water is evenly distributed in the first side water jacket area 1, avoiding local overheating or insufficient cooling, thereby improving the heat exchange efficiency and overall heat dissipation uniformity.

[0063] Specifically, if Figure 2 As shown, the first side water jacket area 1 is provided with four first side cutouts 13 , and the four first side cutouts 13 are distributed at intervals along the flow direction of the cooling water.

[0064] In other embodiments, the second side water jacket area 2 is provided with multiple second side cutouts 22, that is, two, three, four or even more second side cutouts 22 are set in the second side water jacket area 2. The provision of multiple second side cutouts 22 can guide the cooling water in the second side water jacket area 2 at multiple positions, thereby facilitating the diversion of the cooling water to various places, and can better cool the cylinder head area corresponding to the second side water jacket area 2, thereby improving the cooling effect on the cylinder head.

[0065] Multiple second side cuts 22 are spaced apart in the second side water jacket area 2 along the flow direction of the cooling water, that is, the multiple second side cuts 22 can disturb the cooling water along the flow direction of the cooling water, guide part of the cooling water to flow toward the first layer of water jacket portion 3, and flow through the first layer of water jacket portion 3 to the water outlet 12, and at the same time guide another part of the cooling water to flow toward the second layer of water jacket portion 4, and flow through the second layer of water jacket portion 4 to the water outlet 12, and finally converge at the water outlet 12 and be discharged from the water outlet 12.

[0066] The multiple second side cutouts 22 distributed at intervals can ensure that the cooling water is evenly distributed in the second side water jacket area 2, avoiding local overheating or insufficient cooling, thereby improving the heat exchange efficiency and overall heat dissipation uniformity, and at the same time, better guiding and diverting the cooling water.

[0067] Specifically, if Figure 3 As shown, the second side water jacket region 2 is provided with four second side cutouts 22 , and the four second side cutouts 22 are distributed at intervals in the second side water jacket region 2 along the flow direction of the cooling water.

[0068] In some embodiments, at least two first side incisions 13 among the plurality of first side incisions 13 have different opening directions.

[0069] That is, the opening directions of the two first side incisions 13 can be set to be different, other settings can be arbitrary, or the opening directions of all the first side incisions 13 can be set to be different.

[0070] In this way, the flow rate and flow distribution of the cooling water in different areas of the first side water jacket area 1 can be better adjusted to ensure that all parts inside the cylinder head can be fully cooled. At the same time, the different opening directions are also conducive to better turbulence of the cooling water in the first side water jacket area 1, making it easier to divert it to the water outlet 12 and the second side water jacket area 2.

[0071] In other embodiments, at least two second side incisions 22 among the plurality of second side incisions 22 have different opening directions.

[0072] That is, the opening directions of the two second side incisions 22 can be set to be different, or any other setting can be made, or the opening directions of all the second side incisions 22 can be set to be different.

[0073] In this way, the flow rate and flow distribution of the cooling water in different areas of the second side water jacket area 2 can be better adjusted to ensure that all parts inside the cylinder head can be fully cooled. At the same time, the different opening directions are also conducive to better turbulence of the cooling water in the second side water jacket area 2, making it easier to divert it to the first layer water jacket part 3 and the second layer water jacket part 4.

[0074] In some embodiments, the first side water jacket area 1 is provided with a first diversion cutout 14, and the cooling water at the first water inlet 11 is suitable for being diverted toward the first side water jacket area 1 and the second side water jacket area 2 through the first diversion cutout 14. In this way, the cooling water entering the first water inlet 11 can be diverted through the first diversion cutout 14, and part of the cooling water flows to the first side water jacket area 1, and the other part of the cooling water flows to the second side water jacket area 2, so that the cooling water can cover more different structures of the cylinder head.

[0075] Specifically, the first side water jacket area 1 is connected to the second side water jacket area 2, and the first diversion cutout 14 can be set at the front end part of the first side water jacket area 1, so that the first diversion cutout 14 can guide the cooling water of the first water inlet 11 to the connection area between the first side water jacket area 1 and the second side water jacket area 2. In this way, it is beneficial to divert the cooling water flowing into the first side water jacket area 1, so that the diverted cooling water flows to the second side water jacket area 2, which can realize the cooling of the cylinder head structure of the first side water jacket area 1, and also realize the cooling of the cylinder head structure at the connection between the first side water jacket area 1 and the second side water jacket area 2.

[0076] The second side water jacket area 2 is provided with a first guide cutout 23 and a second guide cutout 24. The cooling water at the first water inlet 11 is suitable for flowing to the second side water jacket area 2 through the first guide cutout 23, and the cooling water at the second water inlet 21 is suitable for flowing to the second side water jacket area 2 through the first guide cutout 23 and the second guide cutout 24.

[0077] In this way, the cooling water diverted to the second side water jacket area 2 through the first diversion cutout 14 can be guided to the second side water jacket area 2 through the first guide cutout 23, and the cooling water entering from the second water inlet 21 can be guided to the second side water jacket area 2 through the first guide cutout 23 and the second guide cutout 24, so that the cooling water can cover more different structures of the cylinder head.

[0078] Specifically, the first guide cutout 23 and the second guide cutout 24 both have a guiding function, and the first guide cutout 23 can not only guide the cooling water diverted from the first water inlet 11, but also guide the cooling water entering from the second water inlet 21, allowing the cooling water to flow along a set path so that the cooling water can better fill the second side water jacket area 2.

[0079] Therefore, by setting the first diversion cut 14, the first guide cut 23 and the second guide cut 24 in combination, the contact area between the cooling water and the different structures of the cylinder head can be increased, and the area through which the cooling water flows can take away the heat of the different structures of the cylinder head, thereby improving the cooling effect and cooling uniformity of the cylinder head, thereby reducing the impact of high temperature on the cylinder head and increasing the service life of the cylinder head.

[0080] In some embodiments, as Figure 1 As shown, the angle between the extending direction of the first diverter slit 14 and the extending direction of the first guide slit 23 is a.

[0081] Specifically, the first diversion cutout 14 and the first guide cutout 23 can both be constructed as an inclined structure, wherein the extension direction of the first diversion cutout 14 can be inclined toward the side of the second side water jacket area 2, which is conducive to diverting part of the cooling water toward the second side water jacket area 2, and the extension direction of the first guide cutout 23 can be inclined toward the side of the second side water jacket area 2, which is conducive to guiding the cooling water diverted to the second side water jacket area 2.

[0082] Moreover, the extension direction of the first diversion cutout 14 is different from the extension direction of the first guide cutout 23, that is, the extension directions of the two form an angle a, and the angle a can be set to an acute angle, a right angle, an obtuse angle, etc., thereby forming a stable angle between the first diversion cutout 14 and the first guide cutout 23, so as to respectively realize the diversion and diversion of the cooling water entering the first water inlet 11, so as to achieve the accuracy of the cooling water flow, and after secondary guidance, the cooling water flow is more stable and the cooling effect is better.

[0083] Furthermore, the specific value of the angle a between the extending direction of the first diverter slit 14 and the extending direction of the first guide slit 23 is not limited to that described in this embodiment and can be selectively set according to the actual cylinder head structure.

[0084] In other embodiments, Figure 1 As shown, the angle between the extension direction of the first guide cutout 23 and the extension direction of the second guide cutout 24 is b.

[0085] Specifically, the extension direction of the second guide cutout 24 is inclined toward the first side water jacket area 1, which is beneficial for guiding the cooling water of the second water inlet 21 toward the second side water jacket area 2 close to the first side water jacket area 1, and can well guide the cooling water to the periphery of the spark plug, which is beneficial for cooling the cylinder head around the spark plug.

[0086] Moreover, the extension direction of the first guide cutout 23 is different from the extension direction of the second guide cutout 24, that is, the extension directions of the two form an angle b, and the angle b can be set to an acute angle, a right angle, an obtuse angle, etc., thereby forming a stable angle between the first guide cutout 23 and the second guide cutout 24, and the first guide cutout 23 and the second guide cutout 24 are spaced apart and distributed, so that the cooling water can flow through the gap between the two, and pass through the first guide cutout 23 and the second guide cutout 24 so that more cooling water entering the second water inlet 21 flows between the two and flows toward the spark plug, which can take away the heat on the spark plug and the cylinder head, so as to effectively cool the spark plug and the cylinder head.

[0087] Furthermore, the specific value of the angle b between the extending direction of the first guide slit 23 and the extending direction of the second guide slit 24 is not limited to that described in this embodiment and can be selectively set according to the actual cylinder head structure.

[0088] Therefore, through the above-mentioned arrangement, the cooling water in the first side water jacket area 1 and the second side water jacket area 2 can be effectively diverted and directed so that the cooling water can not only flow through the cylinder head, but also flow to other structures inside the cylinder head, thereby improving the overall cooling effect of the cylinder head, so that the cylinder head maintains a stable operating temperature, thereby reducing the risk of cylinder head cracking.

[0089] Furthermore, it satisfies: b / a=2, that is, the angle b between the extension direction of the first guide cut 23 and the extension direction of the second guide cut 24 is twice the angle a between the extension direction of the first diversion cut 14 and the extension direction of the first guide cut 23. For example, b can be set to 20° and a can be set to 10°, or b can be set to 40° and a can be set to 20°, or b can be set to 60° and a can be set to 30°, or b can be set to 80° and a can be set to 40°, or b can be set to 76° and a can be set to 38°, or b can be set to 90° and a can be set to 45°, or b can be set to 120° and a can be set to 60°, or others. It can be flexibly and selectively set according to actual conditions and is not limited to the present embodiment. It only needs to satisfy b / a=2.

[0090] Therefore, by making the angle b between the extension direction of the first guide cutout 23 and the extension direction of the second guide cutout 24 twice the angle a between the extension direction of the first diversion cutout 14 and the extension direction of the first guide cutout 23, the specific structure of the cylinder head can be better adapted, and the diversion and diversion effects of the cooling water can be improved, so that the cooling water can flow evenly to various areas, thereby improving the uniform cooling effect of the cylinder head as a whole, preventing the cylinder head from having a high thermal load, and thus reducing the risk of cylinder head cracking.

[0091] In some embodiments, the following is satisfied: 30°≤a≤40°.

[0092] That is, the angle a between the extension direction of the first diverter cutout 14 and the extension direction of the first guide cutout 23 can be set to 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, or other angle values ​​within the range of 30° to 40°. In this way, a stable angle between the first diverter cutout 14 and the first guide cutout 23 within the range of 30° to 40° can be formed to better adapt to the structure of the cylinder head and the conditions in the combustion chamber. At the same time, the cooling water entering the first water inlet 11 can be diverted and guided respectively to ensure the accuracy of the cooling water flow. After secondary guidance, the cooling water flow is more stable and the cooling effect is better.

[0093] In other embodiments, the following is satisfied: 60°≤b≤80°.

[0094] That is, the angle b between the extension direction of the first guide cutout 23 and the extension direction of the second guide cutout 24 can be set to 60°, 62°, 64°, 66°, 68°, 70°, 72°, 74°, 76°, 78°, 80°, or other angle values ​​within the range of 60° to 80°. In this way, the angle between the first guide cutout 23 and the second guide cutout 24 can be stably formed within the range of 60° to 80° to better adapt to the structure of the cylinder head and the conditions within the combustion chamber. In addition, the first guide cutout 23 and the second guide cutout 24 are spaced apart, allowing cooling water to flow more fully through the gap between them. Moreover, more cooling water entering the second water inlet 21 through the first guide cutout 23 and the second guide cutout 24 flows between them and toward the spark plug, thereby removing more heat from the spark plug and the cylinder head, thereby further effectively cooling the spark plug and the cylinder head.

[0095] In a further embodiment, the following condition is satisfied: 33°≤a≤37°, thereby further improving the effect of diverting and guiding the cooling water entering the first water inlet 11 .

[0096] Specifically, a can be set to 33°, 33.2°, 34°, 34.5°, 34.8°, 35°, 35.2°, 35.7°, 36°, 36.1°, 36.4°, 36.74°, 36.9°, 37°, or to other angle values ​​within this range. In this way, the angle between the extension direction of the first diversion cutout 14 and the extension direction of the first guide cutout 23 is set accordingly within this range to better guide and divert the cooling water, so that the cooling water entering from the first water inlet 11 can flow more stably and easily to the first side water jacket area 1 and the second side water jacket area 2 respectively, thereby achieving a better cooling effect.

[0097] In a further embodiment, the following angle is satisfied: 55°≤b≤75°, thereby further improving the effect of diverting and guiding the cooling water entering through the first water inlet 11 and the cooling water entering through the second water inlet 21 .

[0098] Specifically, b can be set to 55°, 55.2°, 55.4°, 55.65°, 55.7°, 55.74°, 55.85°, 55.9°, 56°, 56.12°, 56.4°, 56.5°, 56.8°, 56.86°, 56.9°, 60.8°, 62°, 65°, 67.6°, 69°, 70°, 74.5°, 75°, or to other angle values ​​within this range. In this way, the first guide cutout 23 is The angle between the extension direction and the extension direction of the second guide cutout 24 is set accordingly within this range, so that the cooling water entering from the first water inlet 11 is guided to the second side water jacket area 2 through the first diversion cutout 14 and cools the cylinder head around the spark plug, and then is better guided and diverted again to better merge with the cooling water entering from the second water inlet 21, so as to fully cool the second side water jacket area 2 of the cylinder head, form a better cooling effect, and finally flow out from the water outlet 12.

[0099] In some embodiments, the second side water jacket area 2 is further provided with a sand cleaning port 25 , and the first side water jacket area 1 and the second side water jacket area 2 are distributed along a first direction.

[0100] Specifically, the sand cleaning port 25 is used to discharge impurities inside the cylinder head water jacket 100, wherein Figure 1 As shown, the first direction can be the left and right direction, and the first side water jacket area 1 and the second side water jacket area 2 are distributed along the left and right direction, and the second side water jacket area 2 is provided with a sand cleaning port 25 at one end away from the first side water jacket area 1, and the sand cleaning port 25 is open along the left and right direction, so that impurities in the first side water jacket area 1 and the second side water jacket area 2 can be cleaned.

[0101] Furthermore, during long-term use, some sand, metal debris or other impurities may accumulate in the cylinder water jacket. In this way, the deposited particles in the first side water jacket area 1 and the second side water jacket area 2 can be discharged from the sand cleaning port 25 to keep the interior of the cylinder head water jacket 100 clean.

[0102] Therefore, the cylinder water jacket can be cleaned regularly through the sand cleaning port 25, which can ensure that the cooling water can flow smoothly and evenly, provide a stable cooling effect for the engine, and extend the service life of the engine. Setting a sand cleaning port 25 can reduce the structural complexity of the cylinder head water jacket 100.

[0103] The first water inlet 11 and the water outlet 12 are located at both ends of the first side water jacket area 1 in the second direction, and the second water inlet 21 and the sand cleaning port 25 are located at both ends of the second side water jacket area 2 in the second direction. The second direction is perpendicular to the first direction.

[0104] Specifically, if Figure 2As shown, the second direction can be the front-to-back direction, the first water inlet 11 and the water outlet 12 are located at the front and rear ends of the second side water jacket area 2, the second water inlet 21 and the sand cleaning port 25 are located at the front and rear ends of the second side water jacket area 2, and the first direction is perpendicular to the second direction. In this way, the cooling water of the first water inlet 11 and the second water inlet 21 can flow in along the front-to-back direction, and the high-temperature cooling water for cooling the cylinder head structure flows out from the water outlet 12 of the first side water jacket area 1 along the left and right directions, and the deposited particles in the first side water jacket area 1 and the second side water jacket area 2 flow out from the left and right directions.

[0105] Therefore, the sand cleaning port 25 is spaced apart from the water outlet 12, so that the cooling water and impurity cleaning channels can be separated, which can reduce the impurity deposition in the cooling water channel and improve the cooling effect of the cylinder head.
