A power supply system includes a wireless power supply end and a wireless receiving end. The wireless receiving end includes a resonant receiving component and a rectifying and voltage-stabilizing component that is connected to the resonant receiving component to output a voltage-stabilized power supply (VCC). A load sudden-change protection circuit includes an overvoltage protection component and an under-voltage protection component that are each respectively connected to the voltage-stabilized power supply and a load. The overvoltage protection component turns on the load when the voltage of the voltage-stabilized power supply is higher than a first preset voltage due to sudden turn-off of the load. The under-voltage protection component turns off the load when the voltage of the voltage-stabilized power supply is lower than a second preset voltage due to sudden turn-on of the load.

A device for forming inside three-dimensional finned tube by multi-edge ploughing and extruding, comprises a machine frame, a machine head, a supporting mechanism, an axial feeding mechanism and a cutter assembly for forming inside fins. The machine head, the supporting mechanism and the axial feeding mechanism are axially mounted on the machine frame in sequence. The cutter assembly for forming inside fins is mounted on the feeding mechanism. One end of a metal tube to be machined for forming inside three-dimensional fins is clamped on a chunk of a rotary main shaft of the machine head, and the other end thereof is placed on the supporting mechanism. The rotary main shaft of the machine head provides the rotation power for the metal tube, and the axial feeding mechanism drives the cutter assembly to move linearly along a coaxial line of the metal tube and the cutter assembly.
