[0002] Circuit boards, also known as printed circuit boards, realize the miniaturization and visualization of circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards have the characteristics of high density, high precision and small size to meet the development of electronic information technology towards high speed, multi-function, large capacity and small size.
[0003] Existing circuit boards are connected to each other through conductive through holes. As they develop towards high density, high precision, light weight and thinness, the operating heat of the circuit boards will also accumulate and rise. Since the circuit boards themselves have poor heat dissipation properties, as the temperature rises, the heat on the circuit boards cannot be discharged in time. If they are in a high temperature state for a long time, the circuit boards will be easily damaged. Utility Model Content

[0021] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.
[0022] like Figure 1-5As shown, a highly heat-dissipating electrical control circuit board includes a mounting seat 1 and a circuit board body 2. A heat dissipation mechanism 3 is provided on the mounting seat 1. The heat dissipation mechanism 3 includes a heat-conducting copper plate 4 fixedly mounted on the mounting seat 1 and located below the circuit board body 2. Heat dissipation fins 5 are fixedly mounted on both ends of the heat-conducting copper plate 4. A fixing frame 6 is fixedly mounted on both ends of the mounting seat 1. A heat dissipation fan 7 located on one side of the heat dissipation fins 5 is provided on the fixing frame 6. Through the provision of the heat dissipation mechanism 3, the circuit board body 2 can be quickly dissipated. A heat-conducting copper plate 4 is provided between the mounting seat 1 and the circuit board body 2. The heat-conducting copper plate 4 can conduct the heat generated by the circuit board body 2 to the heat dissipation fins 5 on both sides. Then, two heat dissipation fans 7 are started to operate. After the heat dissipation fans 7 operate, the heat dissipated from the heat dissipation fins 5 can be quickly led outward, thereby achieving heat dissipation of the circuit board body 2 and preventing the circuit board body 2 from being damaged due to being in a high temperature state for a long time.
[0023] Two fixed blocks 8 are symmetrically fixedly installed on the surface of the fixed frame 6, and two springs 9 are symmetrically installed inside the fixed blocks 8, and a clamping rod 10 is fixedly installed on one end of the spring 9; two clamping blocks 11 that engage with the clamping rod 10 are fixedly installed on the heat dissipation fan 7, and one end of the clamping rod 10 is set to a cone; two grooves 12 are symmetrically provided on the top of the mounting seat 1, and a screw rod 13 is movably installed inside the groove 12, and a turntable 14 is fixedly installed on the screw 13, and a moving block 15 that is threadedly installed on the screw rod 13 is provided on one side of the turntable 14, and a support rod 16 is fixedly installed on the top of the moving block 15, and a support plate 17 is fixedly installed on one side of the support rod 16, and two rotating rods 18 are symmetrically and movably installed on the support plate 17, and a pressure plate 19 movably connected to the two rotating rods 18 is provided below the support plate 17.
[0024] By setting the fixing block 8, the spring 9, the clamping rod 10 and the clamping block 11, after the heat dissipation fan 7 is installed inside the fixing frame 6, the two clamping blocks 11 on the heat dissipation fan 7 are inserted into the fixing block 8, and the two clamping rods 10 in the fixing block 8 extend and are inserted into the clamping blocks 11 under the support of the spring 9, and the clamping rods 10 and the clamping blocks 11 are engaged to fix the heat dissipation fan 7 to prevent the heat dissipation fan 7 from falling off the fixing frame 6. At the same time, because one end of the clamping rod 10 is tapered, the clamping block 11 is easy to squeeze the clamping rod 10, thereby facilitating the installation and removal of the heat dissipation fan 7; by means of the groove 12, the screw 13, the turntable 14, the moving block 15, the support rod 16, the arrangement of the support plate 17, the rotating rod 18 and the pressing plate 19 can fix the circuit board body 2 on the mounting base 1 according to the size of the circuit board body 2. Rotating the turntable 14 can drive the screw rod 13 to rotate. When the screw rod 13 rotates, it can drive the moving block 15 to move through the thread. The movement of the moving block 15 further drives the support rod 16 and the support plate 17 to move. After the support plate 17 is moved to the top of one end of the circuit board body 2, the two rotating rods 18 are rotated at the same time to make them descend along the threads between the supporting plate 17, so as to drive the pressing plate 19 to descend to press the circuit board body 2, so as to facilitate the installation and fixation of circuit board bodies 2 of different specifications.
[0025] The bottom of the pressing plate 19 is fixedly installed with a rubber pad 20; two limiting grooves 21 are provided on the inner wall of the groove 12, and a limiting block 22 connected to the moving block 15 is slidably installed inside the limiting groove 21; the top of the rotating disk 14 extends to the outside of the groove 12, and the surface is provided with anti-skid grooves 23. The setting of the rubber pad 20 can protect the surface of the circuit board body 2 and prevent the pressing plate 19 from causing wear on the surface of the circuit board body 2; when the moving block 15 moves, the limiting blocks 22 on both sides slide in the limiting grooves 21, which can provide limiting support for the moving block 15 to prevent it from rotating with the screw 13, thereby preventing the support plate 17 from tilting, so as to improve the stability of the pressing plate 19 so that it can better press and fix the circuit board body 2; the top of the rotating disk 14 extends to the outside of the groove 12, so that the worker can contact the rotating disk 14 to push and rotate it to drive the screw 13 to rotate, and the anti-skid grooves 23 on the rotating disk 14 can increase the friction of its surface to prevent slipping when pushing.
[0026] like Figure 1-5 As shown, the working process of the high heat dissipation electrical control circuit board provided in this embodiment is as follows:
[0027] A heat-conducting copper plate 4 is arranged between the mounting base 1 and the circuit board body 2. The heat-conducting copper plate 4 can conduct the heat generated by the circuit board body 2 to the heat dissipating fins 5 on both sides, and then the two heat dissipating fans 7 are started to operate. After the heat dissipating fans 7 operate, the heat dissipated from the heat dissipating fins 5 can be quickly led outward, thereby effectively dissipating the heat of the circuit board body 2; rotating the turntable 14 can drive the screw 13 to rotate, and when the screw 13 rotates, it can drive the moving block 15 to move through the thread, and the movement of the moving block 15 can drive the support rod 16 and the support plate 17 to move. After the support plate 17 is moved to the top of one end of the circuit board body 2, the two rotating rods 18 are rotated at the same time to make them descend along the thread between the support plate 17, so as to drive the pressing plate 19 to descend to press the circuit board body 2, so as to facilitate the installation and fixation of circuit board bodies 2 of different specifications.
[0028] The above description shows and describes the preferred embodiments of the utility model. It should be understood that the utility model is not limited to the form disclosed herein. Modifications and changes made by those skilled in the art without departing from the spirit and scope of the utility model should be within the protection scope of the claims attached to the utility model.
