Description

Technical Field

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

[0002] A stabilized power supply is an electronic device that can provide stable AC or DC power to the load. It includes two categories: AC stabilized power supply and DC stabilized power supply. When the grid voltage or load fluctuates instantly, the stabilized power supply will compensate the voltage amplitude at a response speed of 10-30ms to stabilize it within ±2%. When the stabilized power supply is in use, its internal components will generate a lot of heat. In order to avoid damage to the stabilized power supply due to excessive temperature, the stabilized power supply is generally equipped with a heat dissipation structure. The existing heat dissipation structure has the following problems during use:

[0003] The existing heat dissipation structure of the voltage-stabilized power supply mainly has a heat dissipation fan installed inside the power supply body, and the heat dissipation inside the voltage-stabilized power supply is dissipated by the heat dissipation fan. The heat dissipation effect of the heat dissipation fan is poor. At the same time, the motor also generates heat when the heat dissipation fan is running. This will cause the heat inside the voltage-stabilized power supply to be unable to be discharged in time, resulting in a shortened service life of the voltage-stabilized power supply.
