[0002] A microcontroller is a single-chip microcomputer that integrates the main parts of a microcomputer on one chip. Microcontrollers were born in the mid-1970s. After more than 20 years of development, their costs have become lower and lower, while their performance has become more and more powerful, which has made their applications ubiquitous in all fields.

[0003] Publication number CN218333776U discloses a high heat dissipation microcontroller, including a circuit board, a controller body is fixedly connected to the top of the circuit board, a fixed bin is fixedly connected to the top of the circuit board, and a heat dissipation mechanism is arranged on the top of the fixed bin. Although this type of microcontroller can replace the motor and blades inside the mounting frame through two blocks, so that a motor with a faster rotation speed can be replaced, thereby better dissipating the heat of the controller body. However, when this type of microcontroller is equipped with a cooling fan, the cooling fan is usually fixedly installed, which causes the cooling fan to be unable to adjust its position according to the actual temperature requirement of the controller body, thereby being unable to provide the most effective heat dissipation in a targeted manner, limiting the heat dissipation efficiency, and making it impossible for the controller body to always operate at the optimal operating temperature, affecting the performance and reliability of the device. In addition, since the cooling fan is fixed, when the controller body needs to be repaired or replaced, disassembling the cooling fan may require special tools and complex operating steps, which increases the complexity and time cost of maintenance work.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] See also Figure 1-5 The utility model provides a technical solution: a microcontroller that is easy to disassemble and assemble, comprising a circuit board 1, and a controller body 2 is installed on the side of the circuit board 1. Pins 3 are fixedly installed on the surface of the controller body 2, and the pins 3 are arranged at equal distances on the surface of the controller body 2 to facilitate stable and efficient electrical connection with other devices or boards. Support bars 4 are fixedly installed on the bottom surface of the circuit board 1, and the support bars 4 are symmetrically distributed on the bottom surface of the circuit board 1, which not only enhances the mechanical stability of the circuit board 1, but also helps to disperse the heat generated by the operation of the microcontroller body 2.

[0026] See also Figure 1-5, the surface of the support bar 4 is provided with a side groove 5, and the inner wall of the side groove 5 is slidably connected with a slide bar 6. This sliding connection design allows the slide bar 6 to move freely in the side groove 5, providing flexible adjustment of the position of the cooling fan 8. A vertical plate 7 is fixedly installed at one end of the slide bar 6, and a rubber strip 9 is fixedly installed on the back of the vertical plate 7. The material of the rubber strip 9 is natural rubber, which not only helps to absorb the slight vibration that may be generated by the operation of the equipment, but also prevents damage caused by friction. A cooling fan 8 is fixedly installed on the top surface of the vertical plate 7, and a push plate 10 is fixedly installed on the top of the cooling fan 8. The material of the push plate 10 is PP plastic. This material is selected because of its light and heat-resistant characteristics, which is suitable for frequent operation. By pushing the cooling fan 8 through the push plate 10, the staff can accurately position the cooling fan 8 at the position where the maximum heat dissipation is required according to the temperature requirements of the controller body 2, which can not only provide targeted cooling effects, but also easily remove the cooling fan 8 when the controller body 2 needs to be repaired or replaced, simplifying the maintenance process.

[0027] Embodiment 2

[0028] See also Figure 4-5 , a heat conduction mechanism is provided on the bottom surface of the circuit board 1, and the heat conduction mechanism includes a round block 11, and the round block 11 is fixedly mounted on the bottom surface of the circuit board 1. The round block 11 can be fixed by screws or bonding, and such a mounting method can ensure the stability of the round block 11 on the circuit board 1 and a good heat conduction effect. A circular groove 12 is provided at the bottom end of the round block 11, and a silicone rod 13 is provided on the inner wall of the circular groove 12. A heat spreader 14 is fixedly mounted on the bottom end of the silicone rod 13, and such a fixing method includes bonding or mechanical snapping, so as to facilitate rapid disassembly and reassembly during maintenance. A heat sink 15 is fixedly mounted on the bottom surface of the heat spreader 14, and the materials of the heat sink 15 and the heat spreader 14 are both copper, which provides excellent thermal conductivity. The heat sink 15 is arranged at equal distances on the bottom surface of the heat spreader 14, and such an arrangement helps to optimize air flow, thereby enhancing the heat dissipation effect. The circular groove 12 is the same size as the silicone rod 13. This design ensures that the silicone rod 13 can fit tightly with the circular groove 12, thereby fixing the heat spreader 14 and the heat sink 15 through friction, thereby increasing the overall mechanical stability. A heat dissipation silicone sheet 16 is fixedly mounted on the top surface of the heat spreader 14. The heat dissipation silicone sheet 16 can directly contact the bottom surface of the circuit board 1. This direct contact method improves the efficiency of heat energy transfer and makes the heat dissipation faster, thereby reducing the operating temperature of the circuit board 1 and enhancing the performance stability of the entire device.

[0029] Working principle: The cooling fan 8 is capable of blowing air to the controller body 2, thereby dissipating heat and preventing the controller body 2 from being overheated. At the same time, the staff can push the cooling fan 8 through the push plate 10, and the cooling fan 8 can then drive the vertical plate 7 to move, and the vertical plate 7 can then drive the slide bar 6 to slide in the side groove 5, and then the cooling fan 8 can be moved. In this way, when heat dissipation is needed, the cooling fan 8 can be moved to the controller body 2 for heat dissipation, and when the controller body 2 needs to be disassembled or repaired, the staff can move the cooling fan 8 away by pushing the cooling fan 8, which can facilitate the disassembly and maintenance of the controller body 2. The utility model can accurately position the cooling fan 8 at the position where the maximum heat dissipation is required according to the temperature requirements of the controller body 2 through the movable cooling fan 8, allowing more effective heat dissipation, ensuring that the controller body 2 runs at the optimal temperature, thereby improving performance and reliability, and the movable design of the cooling fan 8 makes it easy to move the cooling fan 8 away when the controller body 2 needs to be repaired or replaced, thereby facilitating related maintenance work and reducing dependence on special tools. The staff can align the silicone rod 13 with the circular groove 12 and insert it. At this time, the silicone rod The friction between 13 and the inner wall of the circular groove 12 can fix the heat spreader 14 and the heat sink 15. After fixation, the heat dissipation silicone sheet 16 can be against the bottom surface of the circuit board 1. At this time, the heat of the circuit board 1 can be conducted to the heat spreader 14 and the heat sink 15. At this time, the heat can be dissipated more efficiently through the heat sink 15, thereby reducing the working temperature of the circuit board 1. When there is too much dust on the surface of the heat sink 15 and maintenance is required, the staff only needs to pull the heat spreader 14 outward with force until the silicone rod 13 is separated from the circular groove 12. At this time, the heat spreader 14 and the heat sink 15 can be removed. 16 directly contacts the bottom surface of the circuit board 1, which can more effectively introduce the heat of the circuit board 1 into the heat spreader 14 and the heat sink 15. This direct contact method improves the efficiency of heat energy transfer and makes the heat dissipation faster, thereby reducing the operating temperature of the circuit board 1 and enhancing the performance stability of the entire device. At the same time, the design of the silicone rod 13 and the circular groove 12 makes the installation and removal of the heat spreader 14 and the heat sink 15 very simple. The staff can complete the installation or removal through simple insertion and pulling actions without complicated tools or processes. This design greatly simplifies maintenance work and saves maintenance time and cost.
