Description

Technical Field

[0002] Wear-resistant surfacing power supplies are welding power systems specifically designed for depositing high-hardness, wear-resistant alloy layers onto workpiece surfaces. Their core function is to provide high current, low voltage, and stable output over extended periods, while also exhibiting characteristics such as resistance to grid voltage fluctuations, low spatter, and high deposition efficiency. These power supplies require prolonged high-load operation, and their internal components (such as semiconductor modules, fast recovery diodes, and transformers) generate significant heat. Traditional air-cooling systems suffer from inefficient airflow organization, low single-fan air pressure, and simple duct designs that cannot cover densely packed heat-generating components, leading to localized overheating and poor heat dissipation efficiency.
