Method and plate apparatus for dew point evaporative cooler

For cooling liquid flow indirect evaporating to wherein dew-point temperature corrective method and device. The plate-type heat exchanger with the dry side and moist side or cryogenic liquid (11) is a punching hole of a gas passage (3, 4 and 5). The liquid flow (1) through the double-sectional the dry side (9) inside, and number of the heat plate. The air flow (2) through the double-sectional the drying and side of the through hole to the moist side (10) is channel (5), then to conduct and a transmission number of heat of radiating of the evaporative cooling and a plate is wherein cooling. The core absorbing material is coupled to the moistness of moist side. The other examples implementation, capable of a drying carrier of the air dehumidifier, the air flow of the repetitive, and is capable of using the supplying core is driven by the part (13) and pump from the water container with water transmitting, and capable of the forced fan or a induced integral.
