AI Technical Summary
The fans in conventional electrical boxes are not cooling enough, which leads to the inability to dissipate heat from high-heat components in a timely manner, and precision electronic components are easily damaged by dust contamination in dusty environments.
The inverter circuit board is combined with a heat sink. The heat sink has heat dissipation strips and holes. The inverter part extends into the holes and, together with the cooling fan, blows air upward to form a heat dissipation channel, increasing the contact area and heat dissipation efficiency.
It improves the heat dissipation effect of the frequency converter, avoids damage caused by insufficient heat dissipation, and adapts to the heat dissipation requirements of dusty environments.
