Description

Technical Field

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

[0002] Normally, it is normal for the power supply to heat up. However, we need to know that the reason why the power supply heats up is caused by the working state of the internal components, which mainly includes the following aspects:

[0003] 1. Low conversion efficiency. The components inside the power supply will generate a certain amount of heat due to the constantly changing current and voltage. If this heat is not effectively utilized, it will be absorbed by the power supply itself and eventually generate heat.

[0004] 2. Poor airflow. There is a fan inside the power supply, whose main function is to remove the heat generated inside the power supply to ensure the power supply temperature is stable. If the fan fails, or the airflow is poor due to dust accumulation inside the power supply, excessive use, etc., then it is normal for the power supply to heat up.

[0005] From the above, we can see that in the absence of an effective heat dissipation path, the power supply will continue to generate heat, which will inevitably affect the service life of the power supply. Therefore, active heat dissipation and dust prevention can ensure the normal operation of the power supply and its service life will not be affected. Utility Model Content
