Description

Technical Field

[0001] The utility model relates to the technical field of voltage-stabilized power supplies, in particular to a heat-dissipating voltage-stabilized power supply. Background Art

[0002] DC regulated power supplies are mainly used to convert AC power into DC power, and can maintain the stability of the output voltage when the voltage of the AC power supply or the load resistance changes. With the development of power supply technology and the improvement of product application requirements, power supply power is also constantly increasing. When working, high-power power supplies can adjust their own power levels according to the usage requirements of the output end, so they are widely used.

[0003] When the voltage-stabilized power supply is not in use, external dust can easily enter the body through the heat dissipation port. Too much dust accumulates inside the voltage-stabilized power supply and easily absorbs moisture in the air, causing a short circuit in the circuit. During use, when the power level is increased, the heat generated by the power supply itself gradually increases. If it is not discharged in time, the power supply will be overloaded, short-circuited or burned. Most of the existing voltage-stabilized power supplies dissipate heat naturally by adding heat sinks or exhaust windows. The heat dissipation efficiency is low and it is suitable for the heat dissipation of small power supplies. When the power supply power is high, the existing natural heat dissipation cannot meet the normal use requirements of the voltage-stabilized power supply. Utility Model Content
