AI Technical Summary

Technical Problem

The existing communication cabinets have low cold source utilization rates, making it difficult to cope with peak load periods. The unreasonable flow channel design leads to frequent high temperature alarms, high energy consumption, and high maintenance costs, failing to meet the high-efficiency thermal management requirements of communication base stations.

Method used

By adopting a compartmentalized layout and optimized arrangement, the split-type rack air conditioner is fully arranged inside the rack. It combines multiple methods such as phase change cladding, radiative cooling coating, natural convection and forced convection for thermal management, optimizes server distribution and flow field design, adds temperature buffer platforms and emergency heat storage sources, and realizes multiple heat dissipation paths and temperature control improvements.

Benefits of technology

It significantly improves airflow heat exchange efficiency, reduces the temperature of heating components, extends equipment lifespan, reduces energy consumption and downtime, simplifies installation and maintenance, expands the normal operating temperature range, and achieves efficient thermal management and energy-saving effects.
