Automatic heat radiation switch power supply

Abstract

The invention relates to the technical field of switch power supplies, in particular to an automatic heat radiation switch power supply which comprises a housing, a water storage tank and a water charge layer, wherein a circuit board on which electronic elements are integrated is mounted inside the housing; heat radiation fins are arranged on the circuit board; heat radiation fans are arranged on the heat radiation fins; the water storage tank is mounted on the housing; the water storage tank is used for collecting rainwater; a water outlet is formed in the bottom of the water storage tank; a water charge switch is arranged at the water outlet; the outer surface of the housing is covered with the water charge layer; the water charge layer is communicated with the water storage tank through the water outlet; water in the water storage tank can flow into the water charge layer; connection of the water charge layer with the water storage tank can be cut off or recovered through the water charge switch; the water charge switch comprises a switch plate, a return spring and a support part. By adopting the automatic heat radiation switch power supply provided by the invention, rainwater of the natural environment is sufficiently utilized, and the problem that a conventional switch power supply is poor in cooling effect is solved.

Description

technical field [0001] The invention relates to the technical field of switching power supplies, in particular to an automatic cooling switching power supply. Background technique [0002] Switching power supply is a kind of power supply that uses modern power electronic technology to control the time ratio of switching on and off to maintain a stable output voltage. Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating and other fields. The working environment of switching power supply is generally harsh. In order to ensure that the switching power supply can work normally in thunderstorm weather, smog weather, and high temperature weather, the switching power supply needs to have excellent rainproof, moisture-proof, lightning-proof, dus...
