A composite-structure wet-film surface air cooler, comprising a plurality of fins (1) parallelly arranged at intervals, and a plurality of heat exchanging pipes (2) passing through the fins (1); a wet film layer (3) is located between two fins (1) to form a "sandwich" structure; and at least one water absorbing belt (4) for introducing water to the wet film layer (3) extends out of the wet film layer (3), or a water dripping device (6) is disposed on the upper part of the wet film layer (3). The composite-structure wet-film surface air cooler on one hand improves the heat dissipation efficiency and coefficient of performance (COP) of condensate water used for the surface air cooler of an air conditioner to reduce air exhaust pressure when the air conditioner cools air, and on the other hand, by being used with anti-freeze, keeps the surface air cooler of the air conditioner from frosting when the air conditioner heats the air in winter. |
