Abstract

The invention discloses a switching power supply system capable of recovering heat, and relates to the field of switching power supplies. The switching power supply comprises a casing, a circuit board arranged in the casing, and a heat conversion device penetrating the interior and the exterior of the casing, wherein the heat conversion device comprises a heat conducting device and a heat collecting device; a gas inlet valve and a gas outlet valve are arranged on the heat collecting device; an air pipe is connected with the gas outlet valve; the air pipe is connected with a power generation device. By centralizedly mounting heat producing electronic devices in the position of the heat conducting device, and guiding heat produced by the switching power supply during operation into the heat collecting device, gas in a heat conducting air pipe is expanded, the gas outlet valve is opened, thermal gas flow is formed and flows at high speed in the air pipe, the fact that heat energy is converted into kinetic energy is realized, the thermal gas flow flowing at high speed can further drive the power generation device to generate electricity, the recycling of heat energy is realized, and the switching power supply system effectively saves energy and is environment-friendly.
