Description

Technical Field

[0001] This utility model relates to the field of heat dissipation mechanism technology, specifically to a heat dissipation device for a power converter. Background Technology

[0002] The heat dissipation device of a power converter is a key component ensuring its stable operation. It mainly consists of heat sink fins, a cooling fan, and heat dissipation channels. The heat sink fins increase the heat dissipation area, enabling rapid absorption of heat generated by the power converter. The cooling fan, installed in a specific location, uses forced airflow to carry heat away from the fins. The heat dissipation channels are carefully designed to guide airflow efficiently, ensuring even heat dissipation. This device features intelligent control, adjusting the fan speed in real time based on the converter's temperature, ensuring effective heat dissipation while reducing energy consumption and noise, effectively extending the power converter's lifespan. Traditional power converter structures, in order to ensure sealing, result in poor heat dissipation performance. Directly creating heat dissipation grilles on the converter's side walls allows dust and moisture to enter the converter's interior, potentially damaging internal electronic components.
