[0002] The Internet of Things communication power supply module is an indispensable part of Internet of Things devices. It provides stable and reliable power support for the devices, ensuring that the devices can work properly in various environments. As a key component among them, the design and implementation of the DC / AC power supply module are crucial for the performance and stability of Internet of Things devices. The DC / AC power supply module is a power supply module specially designed for Internet of Things devices. It can convert direct current (DC) into alternating current (AC) to meet the device's demand for stable power. This power supply module usually has overvoltage and overcurrent protection functions, as well as the ability to adapt to grid voltage fluctuations, ensuring that the device can also operate stably in different grid environments.

[0003] However, under the influence of long-term operation or external environmental factors, the power supply module may overheat, which will affect the efficiency and lifespan of the power supply module, and may even lead to failures and damages. Therefore, the design of the overheat protection mechanism is crucial. Summary of the Utility Model

[0009] Through the above technical solution, when the internal temperature is too high, the blower and the heat dissipation net exchange the air inside the power supply housing with the outside to reduce the heat inside the power supply housing.

[0010] As a further improvement of the above solution, the outer heat dissipation net is arranged on the surface of the power supply housing, the fixing column is arranged inside the through hole, and the front surface of the inner protective net is fixedly connected to the inner wall of the power supply housing.

When the internal temperature is too high, the blower and the heat dissipation net exchange the air inside the power supply housing with the outside to reduce the heat inside the power supply housing. When the temperature inside the power supply housing cannot be controlled by the blower for heat dissipation, through the PWM controller, the PWM controller will automatically reduce the output voltage and current to play a role in overheat protection.

[0015] By setting a temperature sensor in the present utility model, the staff can observe the temperature inside the power supply housing in real time. When the internal temperature cannot be reduced all the time, the overall power-off process is carried out through the temperature display of the temperature sensor to avoid damage to the device.
