Description

Technical Field

[0001] The utility model relates to the technical field of power supply devices, in particular to a bidirectional computer power supply. Background Art

[0002] Computers are weak current products, which means that the working voltage of the components is relatively low, generally within plus or minus 12 volts, and it is direct current, while ordinary city electricity is 220 volts (110 volts in some countries) alternating current, which cannot be used directly on computer components. Therefore, computers, like many home appliances, need a power supply part, which is responsible for converting ordinary city electricity into a voltage that can be used by computers. It is generally installed inside the computer. The working voltage of the core components of the computer is very low, and because the operating frequency of the computer is very high, the power supply requirements are relatively high. The power supply of the computer is a switching circuit, which converts ordinary alternating current into direct current, and then controls the voltage through chopping, and outputs different voltages to computer components such as the motherboard, hard disk, and optical drive;

[0003] According to patent announcement number CN205656577U, a dustproof computer power supply relates to the technical field of computer appliances; a mounting plate is installed at the upper end of a shell, and an input connector and an output connector are installed at both ends of the shell respectively, the input connector is connected to the input end of a transformer, the output end of the transformer is connected to a DC-DC converter, the DC-DC converter is connected to one end of a voltage stabilizing module, and the other end of the voltage stabilizing module is connected to the output connector, and a first filter is installed at the lower end of the shell. However, the operating voltage of the device is low and belongs to direct current, which causes the device to be incompatible with the voltage in many regions and cannot be used. At the same time, the power supply is fixed with bolts, and when the power supply has problems and needs to be repaired, it is inconvenient to disassemble it.

[0004] In view of this, we propose a bidirectional computer power supply. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model supports bidirectional conversion of DC and AC to any power supply system by installing a bidirectional DC converter module. At the same time, the power heat dissipation module adopts an assembleable form. The assembled heat dissipation back plate is slid into the connecting track for assembly, and then the heat dissipation module 1 and the heat dissipation module 2 are slid into the side of the mounting track 1 and installed with the battery panel, which can facilitate the removal and cleaning of the radiator after long-term use. At the same time, the power supply and the chassis mounting surface are separately fixed to the side of the chassis by the mounting plate, and the mounting track 2 at the bottom of the power supply is slid into the slot of the mounting plate for installation, so that when the power supply fails, it can be convenient for maintenance personnel to disassemble. At the same time, the bidirectional DC converter module can realize a high-voltage bidirectional power supply that can be used for large-current inverter testing and realize smooth current switching. During the switching process, there will be no gaps at the intersection, and the current waveform will not have overshoot or undershoot. In this way, the test can be repeated without worrying about overcharging, over-discharging and aging of the rechargeable battery.

[0016] 2. The utility model protects the connection end of the power supply through the overload protection device. When the current in the power supply is too large and the converter is not working, the overload protection device disconnects the connection end, and the power-off module protects the power supply. At the same time, when the power is disconnected, the alarm sounder is triggered to start, so as to prompt the user to make adjustments to avoid damage to the power supply.
