An air channel and a frame for fixing the evaporating pipe members are arranged between the adjacent evaporating pipe members. The surface of the evaporating pipe member is coated with the moisture absorbent material. The water applied on the evaporating pipe member performs thin-film evaporation under the heat released by the cooled working fluid and is taken away by the air force, in order to achieve the goal of heat exchange. The heat exchanger is also provided with a water distributor supplying water on the moisture absorbent material. The front and back sides of the heat exchanger are provided with a porous ventilating guard plate for avoiding water dissipation.
