Description

Technical Field

[0001] This application relates to the technical field of cylinder blocks, and particularly to a low-noise water-cooled cylinder block. Background Art

[0002] A cylinder block is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. Air expands in the engine cylinder to convert heat energy into mechanical energy; gas is compressed by the piston in the compressor cylinder to increase pressure. The cooling methods for cylinder blocks are generally divided into water cooling and air cooling. Water cooling is mainly achieved by adding a water chamber around the cylinder block and filling the water chamber with a coolant, while air cooling is achieved through heat sinks. Both of these structures can achieve the cooling function of the cylinder block to a certain extent, enabling the cylinder block to work properly.

[0003] In related technologies, to solve the problem that for an existing water-cooled cylinder with good heat dissipation effect, when the engine cylinder wall is bored, the structural strength of the cylinder wall will be reduced, and it is quite easy for the cylinder wall to deform during engine operation, resulting in a decrease in the airtightness between the piston and the cylinder wall, and problems such as high fuel consumption and reduced horsepower. The patent with the publication number CN217501808U provides a low-noise water-cooled cylinder block. This low-noise water-cooled cylinder block, through the two-stage design of the lower water jacket, can bore the cylinder wall without replacing the cylinder head, and the structure of the cylinder body and the cylinder wall after boring is still sufficient to support its operation without deformation, thereby effectively reducing the cost of modification or maintenance.

[0004] In the prior art, the traditional design of water-cooled cylinder blocks often focuses on the structural strength and cooling efficiency of the cylinder block, while ignoring the influence of the internal fluid dynamics characteristics of the cylinder block on noise. Therefore, when the water-cooled cylinder block operates at high speed, the flow of cooling water in the cylinder block is prone to generate turbulence and eddies. These unstable fluid motions not only exacerbate the wear of mechanical components but also become one of the main sources of noise, seriously affecting the comfort and environmental performance of the whole vehicle.

[0005] In view of this, a low-noise water-cooled cylinder block is proposed to solve the above problems. Utility Model Content

[0006] To solve the problems raised above, this application provides a low-noise water-cooled cylinder block.

[0007] The low-noise water-cooled cylinder block provided by this application adopts the following technical solutions:

[0008] A low-noise water-cooled cylinder block includes a cylinder main body, a docking pipe and a fitting sleeve. A heat exchange pipe is fixedly installed inside the cylinder main body. A water inlet pipe communicating with the heat exchange pipe is arranged on one side of the cylinder main body. A docking pipe is limit installed on one side of the water inlet pipe. Installation rods are movably installed at the top and bottom of the water inlet pipe. A sliding ring is slidably installed on the outer side of the docking pipe. A damping plate is fixedly installed inside the water inlet pipe. A fitting sleeve is fixedly installed on the inner wall of the water inlet pipe. An installation sleeve is fixedly installed on one side of the damping plate. A movable rod is movably installed inside the installation sleeve. One end of the movable rod is fixedly installed with a plug head corresponding to the fitting sleeve.

[0009] Preferably, heat dissipation fins are arranged on the outer side of the cylinder main body. An installation groove for installing the heat exchange pipe is arranged inside the cylinder main body. The heat exchange pipe is spiral.

[0010] Preferably, the water inlet pipe and the installation rod are movably installed through a rotating seat. An activity groove cooperating with the sliding ring is arranged on the outer side of the docking pipe. The sliding ring and the docking pipe are limited and fixed through a fixing knob.

[0011] Preferably, a clamping groove is fixedly installed at one end of the installation rod. A limiting plate corresponding to the clamping groove is fixedly installed on the outer side of the sliding ring.

[0012] Preferably, a dispersion plate is arranged on the outer side of the installation sleeve. Through holes are arranged on the damping plate.

[0013] Preferably, the installation sleeve and the movable rod are slidably installed. The inner end of the movable rod and the inner wall of the installation sleeve are movably connected through a spring.

[0014] In summary, the present application includes the following beneficial technical effects:

[0015] The docking pipe can be docked with the water inlet pipe. One end of the docking pipe passes through the inside of the water inlet pipe. The sliding ring slides along the inner side of the activity groove, so that the limiting plate and the clamping groove are clamped. The sliding ring and the docking pipe can be limited through the fixing knob, so that the water inlet pipe and the docking pipe can maintain a good docking effect.

[0023] The following will further elaborate on this application in conjunction with the attached Figures 1-6 for a more detailed description.

[0024] The embodiment of this application discloses a low-noise water-cooled cylinder block. Referring to Figures 1-6 , a low-noise water-cooled cylinder block includes a cylinder body 1, a docking pipe 2 and a fitting sleeve 3. A heat exchange pipe 103 is fixedly installed inside the cylinder body 1. A water inlet pipe 102 communicating with the heat exchange pipe 103 is arranged on one side of the cylinder body 1. A docking pipe 2 is limit-installed on one side of the water inlet pipe 102. Installation rods 202 are movably installed at the top and bottom of the water inlet pipe 102. A sliding ring 203 is slidably installed on the outer side of the docking pipe 2. A damping plate 301 is fixedly installed inside the water inlet pipe 102. A fitting sleeve 3 is fixedly installed on the inner wall of the water inlet pipe 102. A mounting sleeve 303 is fixedly installed on one side of the damping plate 301. An activity rod 305 is movably installed inside the mounting sleeve 303. A plug 306 corresponding to the fitting sleeve 3 is fixedly installed at one end of the activity rod 305. The mounting sleeve 303 and the activity rod 305 are slidably installed, and the inner end of the activity rod 305 is movably connected to the inner wall of the mounting sleeve 303 through a spring 307.

[0025] When the water flows, the plug 306 is squeezed, the movable rod 305 moves along the inner side of the mounting sleeve 303, enabling the spring 307 to be compressed. In the inlet and outlet areas of the water inlet pipe 102 and the docking pipe 2, a dispersion plate 304 is provided. When the flow force is too large, the impact force can be absorbed by the damping plate 301, and at the same time, the energy generated by the water flow impact can be dispersed by the dispersion plate 304, further reducing the noise level.

[0026] Refer to Figures 1-3 , heat dissipation fins 101 are provided on the outer side of the cylinder body 1, and an installation groove 104 for installing the heat exchange pipe 103 is provided inside the cylinder body 1. The heat exchange pipe 103 is spiral. The water inlet pipe 102 and the mounting rod 202 are movably installed through a rotating seat 201. An activity groove 204 for cooperating with the sliding ring 203 is provided on the outer side of the docking pipe 2, and the sliding ring 203 and the docking pipe 2 are limited and fixed through a fixing knob 205.

[0027] Through the fixing knob 205, the sliding ring 203 and the docking pipe 2 can be limited, so that a good docking effect can be maintained between the water inlet pipe 102 and the docking pipe 2, and at the same time, water injection operation can be carried out into the water inlet pipe 102 through the docking pipe 2.

[0028] Refer to Figure 4 , a clamping groove 206 is fixedly installed at one end of the mounting rod 202, a limiting plate 207 corresponding to the clamping groove 206 is fixedly installed on the outer side of the sliding ring 203, a dispersion plate 304 is provided on the outer side of the mounting sleeve 303, and a through hole 302 is provided on the damping plate 301.

When the water flows, the plug 306 is squeezed, the movable rod 305 moves along the inner side of the mounting sleeve 303, enabling the spring 307 to be compressed. In the inlet and outlet areas of the water inlet pipe 102 and the docking pipe 2, a dispersion plate 304 is provided. When the flow force is too large, the impact force can be absorbed by the damping plate 301, and at the same time, the energy generated by the water flow impact can be dispersed by the dispersion plate 304, further reducing the noise level.
