[0023] The present invention is further described in detail below in conjunction with the embodiments:
[0024] Example 1
[0025] like Figure 1-5 As shown, the utility model provides a PCB circuit board, including a heat dissipation mechanism 1, the top of the heat dissipation mechanism 1 is fixedly connected to a limiting mechanism 3, the top of the limiting mechanism 3 is sleeved with a fixing mechanism 2, the heat dissipation mechanism 1 includes a water cooling pipe 11, one end of the water cooling pipe 11 is threadedly connected to a sealing plug 12, the bottom of the water cooling pipe 11 is movably connected to a support plate 13 with holes, the bottom of the support plate 13 with holes is sleeved with an electric rotating rod 14, the surface of the electric rotating rod 14 is fixedly connected to a heat dissipation fan blade 15, the tail end of the electric rotating rod 14 is sleeved with a cross support frame 16, and the outer side of the cross support frame 16 is movably connected to a dustproof net 17;
[0026] Specifically, the water cooling pipe 11 can reduce the temperature of the bottom of the shell 31, and is attached to the bottom of the PCB circuit board body 34 through the ventilation hole 32, so that the temperature of the bottom of the PCB circuit board body 34 is introduced into the cold row inside the water cooling pipe 11, thereby reducing the temperature of the PCB circuit board body 34 to ensure that the PCB circuit board body 34 can work efficiently for a long time. Because the bottom of the shell 31 is closed by the cross support frame 16 and the dustproof net 17, the wind can enter the bottom of the shell 31 through the dustproof net 17, and at the same time, the four corners of the PCB circuit board body 34 are attached to the inner side of the anti-slip pad 33, so that the surrounding is connected with the outside. The inner wall of the shell 31 has space for movement. The electric rotating rod 14 is opened to drive the heat dissipation fan blades 15 to rotate, so that the external air can be transmitted from the bottom of the shell to the inside of the shell 31, and the cold row in the water-cooling tube 11 can be cooled. At the same time, the wind can be blown to the bottom of the PCB circuit board body 34, thereby improving the heat dissipation intensity of the PCB circuit board body 34. The dustproof net 17 seals the outside of the cross support frame 16, so as to prevent external dust from entering the bottom of the shell 31, and at the same time prevent dust from covering the bottom of the water-cooling tube 11 and the PCB circuit board body 34, thereby avoiding affecting the heat dissipation effect.
[0027] Example 2
[0028] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the fixing mechanism 2 includes a double-layered plate 21, the inner sleeve of the double-layered plate 21 is provided with a limit plate 22, the inner sleeve of the double-layered plate 21 is provided with an insertion rod 23, the lower surface of the fan-shaped plate of the insertion rod 23 is tightly attached to the upper surface of the double-layered plate 21, the tail end surface of the insertion rod 23 is fixedly connected with an anti-slip ring 24, the inner thread of the limit plate 22 is connected with a fixing bolt 25, and the tail end of the fixing bolt 25 is threadedly connected to the inner part of the insertion rod 23;
[0029] Specifically, the PCB circuit board body 34 is placed in the shell 31, and then the bottom layer of the double-layer press board 21 is placed in the inner wall of the anti-slip pad 33, so that its lower surface is in contact with the upper surface of the PCB circuit board body 34, and is sleeved on the outside of the limit plate 22, and then the insertion rod 23 and the anti-slip ring 24 are inserted into the shell 31, so that the lower surface of the fan-shaped plate of the insertion rod 23 is in close contact with the upper surface of the double-layer press board 21, and then the fixing bolt 25 is screwed into the limit plate 22, and then screwed into the top of the insertion rod 23, so that the insertion rod 23 can be fixed, thereby improving the fixing effect of the double-layer press board 21, and then the fixing strength of the PCB circuit board body 34 can be improved, and the PCB circuit board body 34 can be prevented from shaking during use.
[0030] Example 3
[0031] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the limiting mechanism 3 includes a shell 31, the bottom inner wall of the shell 31 is movably connected to the outside of the dustproof net 17, the bottom inner wall of the shell 31 is fixedly connected to the four ends of the cross support frame 16, the upper surface of the shell 31 is fixedly connected to the bottom of the limiting plate 22, the four corners of the shell 31 are sleeved on the outside of the plug rod 23, the inner four corners of the shell 31 are sleeved on the outside of the anti-slip ring 24, the partition plate surface of the shell 31 is provided with ventilation holes 32, the four corners of the inner wall of the shell 31 are fixedly connected with anti-slip pads 33, the surface of the anti-slip pads 33 is provided with a PCB circuit board body 34, and the upper surfaces of the four corners of the PCB circuit board body 34 are all in contact with the lower surface of the double-layer laminate 21;
[0032] Specifically, the four corners of the PCB circuit board body 34 are placed inside the anti-slip pad 33 to increase the friction with the surface of the PCB circuit board body 34 and improve the fixing strength of the PCB circuit board body 34. The heat at the bottom of the PCB circuit board body 34 is transmitted into the water cooling pipe 11 through the support plate in the middle of the shell 31, thereby reducing the temperature of the PCB circuit board body 34 itself. At the same time, the wind blows to the bottom of the PCB circuit board body 34 through the ventilation hole 32, thereby reducing the temperature of the PCB circuit board body 34.
[0033] The following is a detailed description of the working principle of the PCB circuit board.
[0034] like Figure 1-5 As shown, the four corners of the PCB circuit board body 34 are placed inside the anti-skid pad 33 and are wrapped by the upper part of the shell 31. Then, the double-layer press board 21 is put on the outside of the limit plate 22. Then, the plug rod 23 and the anti-skid ring 24 are inserted into the shell 31, so that the lower surface of the fan-shaped plate of the plug rod 23 is tightly attached to the upper surface of the double-layer press board 21. Then, the fixing bolt 25 is screwed into the limit plate 22 and then screwed into the top of the plug rod 23 to fix the plug rod 23, thereby improving the fixing strength of the PCB circuit board body 34. When the circuit board body 34 is running, the water cooling pipe 11 exports the temperature of the PCB circuit board body 34 through the middle support plate of the shell 31, thereby reducing the temperature of the PCB circuit board body 34, and at the same time, the electric rotating rod 14 is opened to drive the heat dissipation fan blades 15 to rotate, and transmit the external air from the bottom of the shell to the inside of the shell 31, which can cool the cold row in the water cooling pipe 11, and at the same time, can blow the wind to the bottom of the PCB circuit board body 34, thereby improving the heat dissipation intensity of the PCB circuit board body 34.
[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
