[0028] Working principle:

[0029] The heat generated by the oil cylinder 100 during use can be absorbed by the arc-shaped temperature guide copper plate 200, and then conducted to the temperature guide fins 202 to disperse the heat. The inlet pipe 204 can be connected to a water faucet or a water pump to deliver water or cooling liquid. The cooling liquid enters the flow guide cover 201 through the communication hole 206, and then flows through the flow guide channel 203 formed between the staggered temperature guide fins 202, the flow guide cover 201, and the arc-shaped temperature guide copper plate 200. Finally, the cooling liquid is discharged from the outlet pipe 205. The flow guide channel 203 is in an S shape, which can increase the residence time of the cooling liquid in the flow guide cover 201. While the cooling liquid flows, it comes into contact with the temperature guide fins 202 and the arc-shaped temperature guide copper plate 200 and carries away the heat, achieving the cooling effect of the oil cylinder 100. When it is necessary to disassemble the flow guide cover 201, the state of the spring 306 can be compressed, and the mounting nut 305 can be rotated to be loosened from the mounting screw 304. The mounting nut 305 can be separated from the extrusion of the mounting frame two 302. The compressed spring 306 can push the mounting frame one 301 and the mounting frame two 302 to move. After the spring 306 is released, the extrusion force of the threaded seat 300 and the flow guide cover 201 can be reduced. At the same time, with the disassembly of the mounting nut 305, the connection between the mounting frame one 301 and the mounting frame two 302 can be released. At this time, pulling the mounting frame one 301 and the mounting frame two 302 to the two sides respectively can separate the threaded seat 300 and the corresponding flow guide cover 201 from the oil cylinder 100, so as to disassemble and maintain or replace the device. After the arc-shaped temperature guide copper plate 200 is disassembled from the oil cylinder 100, the corresponding guide screw 303 can be rotated to be unscrewed from the mounting screw hole 309 in the threaded seat 300, so as to separate the guide screw 303 and the flow guide cover 201, and replace the corresponding size of the flow guide cover 201 and the arc-shaped temperature guide copper plate 200 according to the size of the oil cylinder 100. Figure 1 With Figure 2 When it is necessary to disassemble the flow guide cover 201, the state of the spring 306 can be compressed, and the mounting nut 305 can be rotated to be loosened from the mounting screw 304. The mounting nut 305 can be separated from the extrusion of the mounting frame two 302. The compressed spring 306 can push the mounting frame one 301 and the mounting frame two 302 to move. After the spring 306 is released, the extrusion force of the threaded seat 300 and the flow guide cover 201 can be reduced. At the same time, with the disassembly of the mounting nut 305, the connection between the mounting frame one 301 and the mounting frame two 302 can be released. At this time, pulling the mounting frame one 301 and the mounting frame two 302 to the two sides respectively can separate the threaded seat 300 and the corresponding flow guide cover 201 from the oil cylinder 100, so as to disassemble and maintain or replace the device. After the arc-shaped temperature guide copper plate 200 is disassembled from the oil cylinder 100, the corresponding guide screw 303 can be rotated to be unscrewed from the mounting screw hole 309 in the threaded seat 300, so as to separate the guide screw 303 and the flow guide cover 201, and replace the corresponding size of the flow guide cover 201 and the arc-shaped temperature guide copper plate 200 according to the size of the oil cylinder 100.

[0030] When it is necessary to disassemble the flow guide cover 201, the state of the spring 306 can be compressed, and the mounting nut 305 can be rotated to be loosened from the mounting screw 304. The mounting nut 305 can be separated from the extrusion of the mounting frame two 302. The compressed spring 306 can push the mounting frame one 301 and the mounting frame two 302 to move. After the spring 306 is released, the extrusion force of the threaded seat 300 and the flow guide cover 201 can be reduced. At the same time, with the disassembly of the mounting nut 305, the connection between the mounting frame one 301 and the mounting frame two 302 can be released. At this time, pulling the mounting frame one 301 and the mounting frame two 302 to the two sides respectively can separate the threaded seat 300 and the corresponding flow guide cover 201 from the oil cylinder 100, so as to disassemble and maintain or replace the device. After the arc-shaped temperature guide copper plate 200 is disassembled from the oil cylinder 100, the corresponding guide screw 303 can be rotated to be unscrewed from the mounting screw hole 309 in the threaded seat 300, so as to separate the guide screw 303 and the flow guide cover 201, and replace the corresponding size of the flow guide cover 201 and the arc-shaped temperature guide copper plate 200 according to the size of the oil cylinder 100.
