Description

Technical Field

[0001] This utility model relates to the field of engine cylinder head cooling technology, specifically to an engine cylinder head with a double-layer cooling water jacket structure. Background Technology

[0002] The cylinder head of the engine is mounted on top of the cylinder block. Since the cylinder head is in direct contact with the high-temperature combustion gases generated during engine operation, the temperature of the cylinder head is always at a high level during engine operation, which puts it under a large heat load and reduces the service life of the cylinder head. Therefore, a cooling water jacket structure is needed to cool the cylinder head.

[0003] However, when using the existing cooling water jacket structure, since most existing engines have a multi-cylinder structure, the coolant travels a long distance inside the heat dissipation channel. This causes the coolant flow rate in different parts of the heat dissipation channel to not be synchronized, forming a cooling dead zone, resulting in a decrease in cooling effect. Furthermore, after long-term use, deposits tend to accumulate inside the cooling water jacket, affecting the cooling effect and making it difficult to promote its use.

[0004] To address this problem, this application provides an engine cylinder head with a double-layer cooling water jacket structure. Utility Model Content

[0005] The purpose of this invention is to provide an engine cylinder head with a double-layer cooling water jacket structure to solve the problems mentioned in the background art, such as the long flow distance of coolant in the heat dissipation channel leading to the formation of a cooling dead zone, and the easy accumulation of deposits inside the cooling water jacket after long-term use, which reduces the cooling effect and affects the cooling performance, resulting in poor performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An engine cylinder head with a double-layer cooling water jacket structure includes a cylinder head assembly, a cooling assembly, and a filter assembly. The cylinder head assembly includes a cylinder head body and a cylinder, with the cylinder located inside the cylinder head body. The cooling assembly is located inside the cylinder head assembly and includes a second channel and a pipe. The second channel is located inside the cylinder head body, and the pipe is fixedly installed on the top of the cylinder head body. The filter assembly is fixedly installed outside the cooling assembly and includes a housing and a filter plate, with the filter plate fixedly installed inside the housing.

[0008] A further improvement of this utility model is that: a fixing hole is provided inside the cylinder head body, and heat dissipation fins are fixedly installed on both sides of the cylinder head body.

[0009] A further improvement of the present invention is that: a first channel is provided inside the cylinder head body, and a first liquid outlet is provided at one end of the first channel.

[0010] A further improvement of this utility model is that: a first connecting channel is provided inside the first channel, the first connecting channel is opened inside the cylinder head body, and the outer shell is fixedly installed at one end of the pipe and the first channel.

[0011] A further improvement of the present invention is that a second liquid outlet is provided on the pipe on one side of the second channel, a second liquid inlet is provided on the pipe on the other side of the second channel, and a second connecting channel is provided at both ends of the second channel.

[0012] A further improvement of this utility model is that the second connecting channel is opened inside the cylinder head body, and the pipe is fixedly installed inside the second connecting channel.

[0013] A further improvement of the present invention is that: a first liquid inlet is installed on the internal thread of the outer shell, an installation hole is provided inside the first liquid inlet, and a gasket is fixedly installed inside the outer shell.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

Through the combined action of the second channel, the pipe and the first connecting channel, by setting a second channel at each cylinder and connecting each second channel through the pipe, and connecting each first channel through the first connecting channel, the coolant travel is reduced and the formation of cooling dead zone is prevented.

[0016] 2. This utility model provides an engine cylinder head with a double-layer cooling water jacket structure.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figure 1-5 As shown, this utility model provides an engine cylinder head with a double-layer cooling water jacket structure, including a cylinder head assembly 1, a cooling assembly 2, and a filter assembly 3. The cylinder head assembly 1 includes a cylinder head body 10 and a cylinder 12. The cylinder 12 is opened inside the cylinder head body 10. A fixing hole 11 is opened inside the cylinder head body 10, and the cylinder head body 10 is connected to the cylinder block through the fixing hole 11. Cooling fins 13 are fixedly installed on both sides of the cylinder head body 10, and the cooling fins 13 dissipate heat from the cylinder head body 10, thereby increasing the heat dissipation effect of the cylinder head body 10.

[0025] like Figure 2-4As shown, the cooling assembly 2 is located inside the cylinder head assembly 1. The cooling assembly 2 includes a second channel 22 and a pipe 24. The second channel 22 is located inside the cylinder head body 10. The pipe 24 is fixedly installed on the top of the cylinder head body 10. A first channel 20 is located inside the cylinder head body 10. A first outlet 21 is provided at one end of the first channel 20. A first connecting channel 23 is provided inside the first channel 20. The first connecting channel 23 is located inside the cylinder head body 10. A second outlet 26 is provided on the pipe 24 on one side of the second channel 22. A second inlet 25 is provided on the pipe 24 on the other side of the second channel 22. Second connecting channels 27 are provided at both ends of the second channel 22. Inside the main body 10, the pipe 24 is fixedly installed inside the second connecting channel 27. When the engine is running, coolant is introduced into the first channel 20 and the second channel 22 through the first inlet 30 and the second inlet 25. After entering the first channel 20 and the second channel 22, the coolant circulates and is then discharged through the first outlet 21 and the second outlet 26. By setting a separate second channel 22 at each cylinder 12 and connecting each second channel 22 through the pipe 24, and connecting each first channel 20 through the first connecting channel 23, the coolant travel is reduced through the combined action of the second channel 22, the pipe 24 and the first connecting channel 23, preventing the formation of a cooling dead zone and the resulting decrease in cooling effect.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, the filter assembly 3 is fixedly installed on the outside of the cooling assembly 2. The filter assembly 3 includes a housing 31 and a filter plate 34. The filter plate 34 is fixedly installed inside the housing 31. The housing 31 is fixedly installed at one end of the pipe 24 and the first channel 20. A first liquid inlet 30 is threaded inside the housing 31. The first liquid inlet 30 has a mounting hole 32 inside. When the filter plate 34 needs to be cleaned or replaced after long-term use, the first liquid inlet 30 is rotated through the mounting hole 32 to remove it, and then the filter plate 34 is cleaned or replaced. A gasket 33 is fixedly installed on the part to seal the connection between the first liquid inlet 30 and the outer casing 31, preventing coolant leakage. Since both the first liquid inlet 30 and the second liquid inlet 25 are located inside the outer casing 31, the coolant will first pass through the filter plate 34 when entering the first channel 20 and the second channel 22. The filter plate 34 filters the coolant and intercepts the deposits in the coolant. Through the combined action of the first liquid inlet 30, the second liquid inlet 25 and the filter plate 34, the accumulation of deposits is prevented from affecting the cooling effect.

[0027] The working principle of this double-layer cooling water jacket structure of the engine cylinder head will be explained in detail below.

[0028] like Figure 1-5 As shown, when using this double-layer cooling water jacket structure for the engine cylinder head, the cylinder head body 10 is connected to the cylinder block through the fixing hole 11. During engine operation, coolant is introduced into the first channel 20 and the second channel 22 through the first inlet 30 and the second inlet 25. Since both the first inlet 30 and the second inlet 25 are located inside the outer casing 31, the coolant, upon entering the first channel 20 and the second channel 22, first passes through the filter plate 34. The filter plate 34 filters the coolant, intercepting deposits. Through the combined action of the first inlet 30, the second inlet 25, and the filter plate 34, the accumulation of deposits is prevented from affecting the cooling effect. After entering the first channel 20 and the second channel 22, the coolant circulates and then... The first outlet 21 and the second outlet 26 are used to discharge the coolant. A second channel 22 is set separately at each cylinder 12 and connected by a pipe 24. At the same time, the first channel 20 is connected by a first connecting channel 23. The combined action of the second channel 22, the pipe 24 and the first connecting channel 23 reduces the coolant's travel distance and prevents the formation of a cooling dead zone, which would reduce the cooling effect. Meanwhile, heat dissipation fins 13 are set on both sides of the cylinder head body 10 to dissipate heat from the cylinder head body 10 and increase the heat dissipation effect. When the filter plate 34 needs to be cleaned or replaced after long-term use, it can be removed by rotating the first inlet 30 through the mounting hole 32 and then cleaning or replacing the filter plate 34.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
