AI Technical Summary
The existing high-voltage switchgear cannot have ventilation holes on the left, right and rear sides, which makes it difficult for airflow to penetrate the interior and affects the heat dissipation effect, especially the heat-generating components on the rear side.
A semiconductor dehumidification device is installed inside the high-voltage cabinet, and an airflow channel is formed by the combination of the first double-row fan, the second double-row fan and the third double-row fan to ensure that the airflow runs through the inside of the cabinet. Combined with the design of the ventilation duct and the adjustment seat, the airflow path is optimized to improve heat dissipation efficiency.
It effectively prevents condensation, improves the heat dissipation of internal components of the high-voltage cabinet, ensures that airflow can better penetrate the cabinet, and solves the heat dissipation problem caused by placement against the wall.
