AI Technical Summary
The existing power distribution cabinet cannot effectively guide airflow according to the heat generation of different components during the heat dissipation process, resulting in poor heat dissipation performance.
A power distribution cabinet was designed with a built-in baffle and drive assembly. The airflow direction is changed by the rotation of the baffle, so that it accurately reaches the surface of the high-heat-generating element. Combined with the sliding of the baffle to adjust the airflow of the vent, the airflow is rationally distributed.
This achieves a reasonable distribution of airflow, improves the heat dissipation efficiency of the internal components of the distribution cabinet, and ensures the normal operation of the equipment.
