The control switch 3 is installed at the left end of the output control power box 1. The output port 4 is arranged at the rear end of the output port 4. The fitting block 5 is arranged at the front end of the output control power box 1. The fitting block 5 is in fitting connection with the top of the auxiliary cooling device 6. The output control power box 1 can adopt a multi-line off-the-shelf circuit control module of the MLG model.

[0026] Please refer to Figure 3 and Figure 4, the present utility model provides a low-power multi-output power supply circuit. The auxiliary cooling device 6 includes a mounting frame 61, a fixing groove 62, a fixing block 63, a refrigeration pump 64, and a gas guide cover 65. A fixing groove 62 is provided at the top of the mounting frame 61, a fixing block 63 is provided at the bottom of the mounting frame 61, the refrigeration pump 64 is installed at the lower end inside the mounting frame 61, the refrigeration pump 64 is communicated with the bottom of the gas guide cover 65, the refrigeration pump 64 and the gas guide cover 65 are arranged in parallel inside the mounting frame 61, and the fixing blocks 63 are all arranged at the same horizontal level at the bottom of the mounting frame 61.

[0027] In this embodiment, the fixing grooves 62 are grouped in twos, and two groups of fixing grooves 62 are symmetrically arranged at the top of the mounting frame 61. The cross-section of the mounting frame 61 presents a "U" structure.

[0028] Please refer to Figure 5 , the present utility model provides a low-power multi-output power supply circuit. The gas guide cover 65 includes an air inlet conduit 651, a gas storage cover 652, an air supply pipe 653, and a gas guide cover 654. The air inlet conduit 651 is connected to the right end of the refrigeration pump 64, the air inlet conduit 651 is fixed inside the mounting frame 61, the air inlet conduit 651 is communicated with the bottom of the gas storage cover 652, the gas storage cover 652 is fixed to the top of the mounting frame 61, the gas storage cover 652 is communicated with the right end of the air supply pipe 653, a gas guide cover 654 is provided at the top of the air supply pipe 653, and the gas guide cover 654 is connected to the bottom of the output control power box 1.

[0029] In this embodiment, multiple groups of gas guide covers 654 are provided at the top of the air supply pipe 653, and the top of the gas guide cover 654 is of a funnel-shaped structure.

[0030] Refer to Figures 1-5 , during use, the output control power box 1 is vertically placed on the top of the mounting frame 61, so that the fitting block 5 is fitted with the fixing groove 62, ensuring that the output control power box 1 can be fitted and fixed on the top of the mounting frame 61. Furthermore, the output control power box 1 is fixed on the top of the mounting frame 61, enabling the refrigeration equipment installed inside the mounting frame 61 to play an auxiliary cooling role for the output control power box 1;

[0031] By starting the refrigeration pump 64 to inhale gas and cool it down, cold air flows into the interior of the intake duct 651. Under the guidance of the intake duct 651, the cold air is promoted to flow into the interior of the air storage cover 652, enabling the air storage cover 652 to supply cold air to the two groups of air supply pipes 653. With the air guide cover 654 installed at the top of the two groups of air supply pipes 653, the cold air is evenly distributed at the bottom of the output control electric box 1, playing an auxiliary refrigeration role for the output control electric box 1. Furthermore, by setting the air guide cover 65 in cooperation with the refrigeration pump 64, it plays an auxiliary refrigeration role for the output control electric box 1. Thus, by arranging the auxiliary cooling device 6 at the bottom of the output control electric box 1, it assists the output control electric box 1 in heat dissipation, preventing the internal transmission components of the output control electric box 1 from operating in a relatively high-temperature environment during long-term use due to the limitation of the heat dissipation structure. This solves the problem that in the original equipment, due to the overly simple heat dissipation structure, the heat dissipation structure of the equipment cannot ensure good heat dissipation during long-term use, resulting in the output components inside the equipment possibly needing to operate in a relatively high-temperature environment.

[0032] Furthermore, connect the power supply cable 2 to the power supply device. By clicking the control switch 3, the output control electric box 1 plays a role in current conversion, and the output control electric box 1 can well control the frequency of the current flowing into different groups of output ports 4, thereby ensuring that different groups of output ports 4 can output currents of different frequencies, and thus completing the work of multi-channel output power supply.

The wiring diagram of the power element and the power supply are common knowledge in the art, and the present utility model mainly protects mechanical devices, so the control mode and wiring layout of the present utility model will not be explained in detail.
