How Air-Water Combined Cooling Tunnels Works?
Combined air-water cooling tunnels integrate both cooling methods into a single system. The most common configuration applies convection air cooling from above and intensive cold water contact cooling from below. This dual-action approach leverages the strengths of both media while mitigating their individual weaknesses.
Hybrid cooling systems can be classified by how air and water travel through the system—in parallel, in series, or a mixture of both. A parallel flow system supplies identical inlet conditions to each section, while a series flow system moves the working fluid sequentially through the hybrid system.
Some hybrid systems are "delugeable"—meaning a single section can operate either wet or dry depending on ambient conditions and performance requirements. During cold ambient periods, the system functions as a dry cooling system. During hot periods or when a performance boost is needed, the finned tube bundles are deluged with water, enabling evaporative cooling.
