[0001] This utility model relates to the field of power adapter technology, specifically a high-power power adapter with good heat dissipation. Background Technology

[0002] A power adapter is a power conversion device for small portable electronic devices and appliances. It is generally composed of components such as a casing, transformer, inductor, capacitor, control IC, and PCB board. Its working principle is to convert AC input into DC output.

[0003] During the use of high-power power adapters, the internal electronic components generate a significant amount of heat. If this heat cannot be dissipated in time, the internal temperature of the power adapter will rise, which will not only affect the power adapter's efficiency and stability but may also shorten its lifespan and even pose safety hazards.

[0004] Therefore, this utility model provides a high-power power adapter with good heat dissipation to solve the above problems. Utility Model Content

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0025] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1 to 6 This application provides a high-power power adapter with good heat dissipation, including a bottom shell 1. A top shell 4 is fixedly installed on the top of the bottom shell 1 by bolts. The bottom shell 1 and the top shell 4 together constitute the outer shell of the adapter, which plays a role in protecting the internal components. A main control circuit board 7 is fixedly installed inside the bottom shell 1 by screws. The main control circuit board 7 integrates various electronic components and is the core component of the adapter to realize power conversion.

[0027] A heat dissipation assembly 2 is provided between the inner and outer sides of the top shell 4. The heat dissipation assembly 2 includes a top plate 26, which is fixedly installed on the top of the top shell 4 by welding. A shell 21 is fixedly installed on the top of the top plate 26 by welding. Side panels 22 are fixedly installed on both the left and right sides of the shell 21 by welding. The shell 21, side panels 22 and top plate 26 together form a heat dissipation cavity. An air outlet slot 23 is provided inside the top of the shell 21 to exhaust hot air from the heat dissipation cavity. A motor 24 is fixedly installed on the inner top of the shell 21 by screws. The output end of the motor 24 is connected by a coupling. The device is fixedly equipped with a cooling fan 25, which is located below the air outlet slot 23. The motor 24 drives the cooling fan 25 to rotate, accelerating the airflow. An air outlet slot 28 is opened inside the top plate 26, which is located below the cooling fan 25. Hot air inside the bottom shell 1 can enter the heat dissipation cavity through the air outlet slot 28 and then be discharged by the cooling fan 25 through the air outlet slot 23. Rubber blocks 6 are glued and fixedly installed at the four corners of the bottom of the bottom shell 1. The rubber blocks 6 increase the friction between the adapter and the placement surface, play a role in preventing slippage, and also reduce the vibration of the adapter during operation.

[0028] Multiple temperature sensors 8 are fixedly installed on the side wall of the bottom shell 1 with screws. The temperature sensors 8 are electrically connected to the main control circuit board 7 through wires. The temperature sensors 8 can detect the temperature inside the bottom shell 1 in real time and transmit the temperature signal to the main control circuit board 7. The cooling fan 25 is electrically connected to the main control circuit board 7 through wires. The main control circuit board 7 can control the start, stop and speed of the cooling fan 25 according to the temperature signal transmitted by the temperature sensors 8. When the temperature is low, the cooling fan 25 can run at low speed or stop running; when the temperature rises to a certain threshold, the cooling fan 25 starts to run at high speed to enhance the heat dissipation effect.

[0029] A wiring slot 3 is fixedly installed inside the right side of the bottom shell 1 by screws, and a wire 5 is fixedly installed on the left side of the bottom shell 1 by a fixing sleeve. Both the wiring slot 3 and the wire 5 are electrically connected to the main control circuit board 7 through wires. The wiring slot 3 is used to connect to an external power source, and the wire 5 is used to connect to electrical equipment to realize the transmission of electrical energy.

[0030] Air inlet slots 27 are provided on both the left and right sides of the bottom shell 1. The left and right air inlet slots 27 are located on the left and right sides of the main control circuit board 7, respectively. External cold air can enter the bottom shell 1 through the air inlet slots 27 and exchange heat with the main control circuit board 7. Then the hot air enters the heat dissipation cavity through the air outlet slots 28 and is finally discharged, forming a complete air circulation heat dissipation path.

[0031] The bottom of the top plate 26 is integrally formed with multiple heat-conducting fins 29. The lengths of the heat-conducting fins 29 are not uniform. The lengths of the heat-conducting fins 29 are set according to the different heights of the main control circuit board 7 below, ensuring that each heat-conducting fin 29 can be close to the main control circuit board 7. Generally, the distance is controlled between 1-3mm, so that the heat generated by the main control circuit board 7 can be absorbed more efficiently.

[0032] The outer shell 21, side panel 22, top plate 26, air outlet slot 23, and heat-conducting fins 29 are all made of aluminum alloy. Aluminum alloy has good thermal conductivity and processing performance, and is integrally molded through die casting. The integrally molded structure makes the heat transfer between these components smoother, reduces thermal resistance, and improves heat dissipation efficiency.

[0033] The main control circuit board 7 uses an STM32F103C8T6 chip, which integrates an ARM Cortex-M3 core, a 12-bit ADC, multiple GPIOs, and a UART / I2C communication interface. It can not only realize the core functions of the adapter such as AC-DC conversion control and output voltage and current regulation through built-in algorithms, but also receive signals from the temperature sensor 8 and intelligently control the cooling fan 25, thus fulfilling the dual responsibilities of power conversion and heat dissipation management. The temperature sensor 8 uses a DS18B20, which is a single-bus digital temperature sensor that supports wide temperature measurement from -55℃ to 125℃. It communicates with the main control board through a single signal line to provide real-time feedback on the internal temperature to ensure the safe operation of the adapter.

[0034] The working principle of this embodiment is as follows: When the adapter is working, the electronic components on the main control circuit board 7 generate heat, which is transferred to the surrounding air. At the same time, the heat-conducting fins 29 absorb the heat of the main control circuit board 7 and transfer it to components such as the top plate 26 and the outer shell 21. The temperature sensor 8 detects the temperature inside the bottom shell 1 in real time and sends the temperature information to the main control circuit board 7. When the temperature is lower than the set threshold, the main control circuit board 7 controls the cooling fan 25 to not work or to work at a low speed. When the temperature is higher than the set threshold, the main control circuit board 7 controls the motor 24 to drive the cooling fan 25 to rotate at high speed. At this time, the cold air outside the bottom shell 1 enters the interior through the air inlet slot 27 and exchanges heat with the main control circuit board 7 and the heat-conducting fins 29. The hot air enters the heat dissipation cavity through the air outlet slot 28 and is finally discharged through the air outlet slot 23 under the action of the cooling fan 25, thereby achieving efficient heat dissipation.
