GMA Intelligent Cabinet Dedicated to Computing Power Micro - modules  

Adopting a brand - new GMA cabinet architecture, it is an integrated closed hot - aisle enclosed dedicated rack. The front door is designed with a high - density honeycomb mesh door, and the ventilation rate reaches 76% of the ventilation area. The front door is pre - installed with a TFC 4.3 - inch intelligent control screen, which can collect and accurately detect the temperature and humidity at 3 points (upper, middle and lower) in the hot zone, supporting the precise detection of the micro - environment in the high - computing - power machine room. The rear door is an advanced all - glass sealed door. The hot - aisle enclosure supports the independent snap - opening of each door. Both ordinary locks and intelligent locks can be installed to achieve one - key snap - opening, preventing high temperatures and overheating.

※Intelligent Exhaust System

Control Logic: The temperature sensors inside the hot aisle collect data and transmit it to the power environment

monitoring system. The system sets two temperature thresholds: When the real-time temperature exceeds Threshold 1

(typically set at 40°C), the exhaust fans activate to discharge heat. This temperature ensures the return air to the air

conditioner falls within its highest cooling efficiency range,reducing overall module power consumption.
