通风底板，CVB

Feature: Zinc plated steel ventilated bottom plates for floor standing enclosures.

Advantage: The bottom plates allow natural ventilation into the enclosure improving the air circulation.

Benefit: The plates allow air to enter from the bottom of the enclosure. The air will cool components and then raise due to the increase in temperature. The hot air can then be extracted from the enclosure using other peripherals such as the roof fan unit, RFU.

Comment: A ventilated plinth, PV, is recommended to be mounted in combination with the ventilated bottom plates.
