Description

Technical Field

[0001] The utility model relates to the technical field of power protection, in particular to an active protection device for a computer power supply. Background Art

[0002] Power protection is an important measure to ensure that the power supply system and its connected load devices are protected from various faults and abnormal conditions. The power supply is the basis for the normal operation of various devices and systems, and its stability and reliability directly affect the operation of the entire system. Therefore, power protection not only concerns the safety of the power supply device itself, but also relates to the stable operation of the entire power system and the connected devices. There are two implementation forms of power protection: active and passive.

[0003] Existing power protection devices are often assembled with the power supply. The power supply and related protection devices generate heat during operation, and the heat accumulates in the power supply box. Even if there is a heat dissipation component, it is difficult to keep the power supply working at an appropriate temperature, which is not conducive to the long-term use of the power supply. For this reason, an active protection device for a computer power supply is proposed for improvement. Summary of the Utility Model

[0006] To achieve the above purpose, an embodiment of one aspect of the utility model provides an active protection device for a computer power supply, including a power supply box, wherein air holes are formed on the side surface of the power supply box, a connection port is fixedly connected to one side of the power supply box, a switch button is arranged on one side of the power supply box, a fan is arranged in the power supply box, and a grille is arranged outside the fan;

An active PFC component is arranged in the power supply box. The active PFC shapes the input current before the rectifier bridge by introducing a special circuit, making its waveform as close to a sine wave as possible and in the same phase as the input voltage waveform. In this way, the phase difference between the current and the voltage is reduced, and the power factor is improved. The adaptive voltage component can automatically adjust to adapt to voltage fluctuations in different regions, ensuring the stability and reliability of the power supply. The air holes allow the gas inside and outside the power supply box to circulate, providing conditions for the heat inside the power supply box to dissipate outward.

[0011] Preferably, according to any of the above solutions, the switch button is arranged on one side of the connection port, and there are several heat dissipation strips evenly arranged at the end of the power supply box.

The heat dissipation strip has a certain heat dissipation area, which can accelerate the heat dissipation of the power supply box and improve the heat dissipation efficiency. The heat insulation board blocks the heat between the power supply box and the installation frame, preventing the heat generated by the protection components from being transferred to the internal components of the power supply box.

[0013] Preferably, according to any of the above solutions, the installation frame adopts a rectangular structure, and the partition board adopts a cross-shaped structure and is arranged in the middle of the installation frame.

The heat generated by the operation of each protection component dissipates outward through the through - holes. The heat generated by both is blocked by the heat insulation plate and is difficult to transfer to each other, thus reducing the heat dissipation pressure of the power supply and being beneficial to the long - term use of the power supply.
