Method and plate apparatus for dew point evaporative cooler using a trough wetting system

This invention is a special plate for an evaporative cooler that cools air without adding moisture to it. One side of the plate stays dry while the other side is kept wet by a wick and a system of small troughs. As warm air flows across the dry side, its heat transfers through the plate to the wet side, where evaporation cools the plate and the air. The claims describe a plate with specific channels on both sides, often crossing each other, to guide the air and liquid.

Why it matters: Advanced manufacturing techniques like 3D printing have made creating complex, custom heat exchanger plates with intricate channels and perforations much more feasible and cost-effective since 2002.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateCustom plate channels, perforations, wick material.
