Description

Technical Field

[0001] This utility model relates to a water-cooled heat dissipation structure, and more particularly to an integrated water-cooled heat dissipation structure for engine cylinder heads, belonging to the field of engine cylinder head technology. Background Technology

[0002] The engine cylinder head is one of the core components of an internal combustion engine. Located at the top of the engine block, it, together with the piston and cylinder wall, forms the combustion chamber and undertakes key functions such as sealing, gas flow control, and heat dissipation.

[0003] The existing engine cylinder head water-cooled heat dissipation structure uses coolant flowing inside the coolant tank to remove the heat generated by the engine cylinder for cooling. However, the coolant entering the coolant tank is prone to impurities after long-term use, or water stains may form when the temperature is too high, which seriously affects the flow of coolant and also affects the heat dissipation effect. Moreover, it is difficult to clean impurities or water stains in the closed cooling channel. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated water-cooled heat dissipation structure for engine cylinder heads that can filter cooling water.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An integrated water-cooled heat dissipation structure for an engine cylinder head includes an engine end cover. The engine end cover has multiple cooling water grooves inside. Each cooling water groove has a connector at both ends. A water inlet is installed on one side of the engine end cover, and a water outlet is installed on the other side. The connector on one side is connected to the water inlet, and the connector on the other side is connected to the water outlet. A filter structure is provided inside the water inlet.

[0007] Furthermore, the inlet cylinder and the outlet cylinder are symmetrically distributed, with an inlet pipe at the upper end of the inlet cylinder and an outlet pipe at the upper end of the outlet cylinder.

[0008] Furthermore, the filter structure includes a mounting base, which is fixedly installed at the lower end of the water inlet cylinder. The filter screen passes through the mounting base and is inserted inside the water inlet cylinder. The lower end of the water inlet cylinder is inserted inside the mounting base and is equipped with a mounting head. A connecting component is provided between the mounting head and the mounting base.

[0009] Furthermore, the upper end of the filter screen is movably inserted inside the water inlet cylinder, the filter screen is in contact with the inner wall of the water inlet cylinder, and the filter screen is smaller than the inner diameter of the mounting base.

[0010] Furthermore, an installation ring is fixedly installed inside the filter screen cover, and a pop-out spring is installed at the upper end of the water inlet cylinder. The lower end of the pop-out spring is inserted inside the filter screen cover and fits against the installation ring.

[0011] Furthermore, one end of the water inlet pipe is located above the filter screen, and the inner diameter of the water inlet pipe is smaller than the inner diameter of the mounting ring.

[0012] Furthermore, the connecting component includes an assembly groove, which is U-shaped and located on both sides of the mounting base. Both sides of the mounting base are provided with mounting grooves that connect to the assembly groove.

[0013] Furthermore, both sides of the mounting head are provided with movable grooves. A mounting rod is movably inserted through one end of the movable groove. One end of the mounting rod passes through the mounting groove and is movably inserted inside the mounting groove and is fitted with a mounting block. The mounting block is engaged with the mounting groove. The other end of the mounting rod is movably inserted inside the movable groove and is fitted with a movable block. A support spring connected to the movable block is sleeved on the surface of the mounting rod. A sliding groove is provided on one side of the movable groove. A slider is movably inserted inside the sliding groove, and one end of the slider is connected to the movable block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. In this application, cooling water enters the interior of the inlet cylinder through the inlet pipe, and then enters the interior of multiple cooling water tanks through the connector. The cooling water flows inside the cooling water tanks to remove heat from the engine cylinder head, achieving a good heat dissipation effect. The cooling water that has removed heat enters the interior of the outlet cylinder through the connector and is discharged through the outlet pipe, facilitating the return and reuse of cooling water. When the cooling water enters the interior of the inlet cylinder through the inlet pipe, it passes through the filter screen and is filtered by the filter screen, achieving the filtration and collection of impurities in the cooling water, preventing impurities in the cooling water from entering the interior of the cooling water tanks and affecting the heat dissipation effect and the operation of the water cooling structure.

[0016] 2. In this application, the user pushes the slider to move it along the slide groove. The slider drives the movable block to move, which in turn drives the movable block, the mounting rod, and the mounting block to move in sequence, so that the mounting block can be pulled out from the inside of the mounting groove. When the mounting block is separated from the mounting groove, the mounting rod can be pulled out from the inside of the mounting groove, the mounting head can be pulled out from the inside of the mounting base, and the filter screen can be pulled out from the inside of the water inlet cylinder, which is convenient for cleaning or replacing the filter screen.

[0023] The technical solution of this utility model will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 3 As shown, the integrated water-cooled heat dissipation structure for engine cylinder head provided in this embodiment includes an engine end cover 1. Multiple cooling water grooves 6 are provided inside the engine end cover 1. Connectors 7 are provided at both ends of the cooling water grooves 6. A water inlet cylinder 2 is installed on one side of the engine end cover 1, and a water outlet cylinder 4 is installed on the other side of the engine end cover 1. The connector 7 on one side is connected to the water inlet cylinder 2, and the connector 7 on the other side is connected to the water outlet cylinder 4. A filter structure is provided inside the water inlet cylinder 2. The water inlet cylinder 2 and the water outlet cylinder 4 are symmetrically distributed. A water inlet pipe 3 is provided at the upper end of the water inlet cylinder 2, and a water outlet pipe 5 is provided at the upper end of the water outlet cylinder 4.

[0025] In this embodiment, cooling water enters the interior of the inlet cylinder 2 through the inlet pipe 3, and then enters the interior of multiple cooling water tanks 6 through the connector 7, so that the cooling water flows inside the cooling water tanks 6 to remove the heat from the engine cylinder head, which has a good heat dissipation effect. The cooling water that has removed the heat enters the interior of the outlet cylinder 4 through the connector 7 and is discharged through the outlet pipe 5, which facilitates the return and reuse of the cooling water.

[0026] like Figures 1 to 3As shown, the integrated water-cooled heat dissipation structure for engine cylinder head provided in this embodiment includes a filter structure comprising a mounting base 8, which is fixedly installed at the lower end of the water inlet cylinder 2. A filter screen 10 passes through the mounting base 8 and is inserted inside the water inlet cylinder 2. The lower end of the water inlet cylinder 2 is inserted inside the mounting base 8 and is equipped with a mounting head 9. The upper end of the filter screen 10 is movably inserted inside the water inlet cylinder 2. The upper end of the filter screen 10 is in contact with the upper end of the inner wall of the water inlet cylinder 2. The inner diameter of the water inlet pipe 3 is smaller than the inner diameter of the mounting ring 11.

[0027] In this embodiment, when cooling water enters the water inlet cylinder 2 through the water inlet pipe 3, it will be filtered by the filter screen 10 to filter and collect impurities in the cooling water, so as to prevent impurities in the cooling water from entering the cooling water tank 6.

[0028] like Figures 1 to 3 As shown, the integrated water-cooled heat dissipation structure for engine cylinder head provided in this embodiment has a connecting component between the mounting head 9 and the mounting base 8. The connecting structure includes an assembly groove 13, which is U-shaped and located on both sides of the mounting base 8. Both sides of the mounting base 8 have mounting grooves 14 connected to the assembly groove 13. Both sides of the mounting head 9 have movable grooves. One end of the movable groove is movably inserted with a mounting rod 16. One end of the mounting rod 16 passes through the assembly groove 13 and is movably inserted inside the mounting groove 14, and a mounting block 15 is installed thereon. The mounting block 15 is engaged with the mounting groove 14. The other end of the mounting rod 16 is movably inserted inside the movable groove and a movable block 17 is installed thereon. A support spring 18 connected to the movable block 17 is sleeved on the surface of the mounting rod 16. A sliding groove 19 is provided on one side of the movable groove. A slider 20 is movably inserted inside the sliding groove 19, and one end of the slider 20 is connected to the movable block 17.

[0029] In this embodiment, the user pushes the slider 20 to move it along the slide groove 19. The slider 20 drives the movable block 17 to move, and in turn drives the mounting rod 16 and the mounting block 15 to move. The mounting block 15 is pulled out from the inside of the mounting groove 14. When the mounting block 15 is separated from the mounting groove 14, the mounting rod 16 can be pulled out from the inside of the assembly groove 13, the mounting head 9 can be pulled out from the inside of the mounting base 8, and the filter screen 10 can be pulled out from the inside of the water inlet cylinder 2, which facilitates the cleaning of the filter screen 10.

[0030] like Figures 1 to 3 As shown, in this embodiment, the integrated water-cooled heat dissipation structure for engine cylinder head has an installation ring 11 fixedly installed inside the filter screen 10, a pop-out spring 12 installed at the upper end inside the water inlet cylinder 2, the lower end of the pop-out spring 12 inserted inside the filter screen 10 and in contact with the installation ring 11, and one end of the water inlet pipe 3 located above the filter screen 10.

[0031] In this embodiment, when the mounting head 9 is disengaged from the mounting base 8, the filter screen 10 pops out under the action of the mounting ring 11 and the pop-out spring 12, so that the filter screen 10 moves quickly to the outside of the water inlet cylinder 2, which facilitates the quick disassembly of the filter screen 10.
