Abstract:
An evaporative heat exchanger of a cooling medium condenser with a coil of streamline tubes and a reduced number of cooling fins comprising:a) a plurality of cooling fins disposed vertically in parallel having a wide interval between adjacent fins respectively; b) a plurality of streamline cross sectional tubes extending laterally through said cooling fins to form a medium cooling coil; c) a recycling water feeding system feeding water onto a surface of said streamline tubes and having: i) a water distributor located above said cooling fins for seeping water drops gently and evenly onto said streamline tubes; ii) a water tank located under said cooling fins to supply evaporated water and to collect residual water from said streamline tubes; iii) a water pump delivering water from said water tank to said water distributor for recycling; and iv) a recycling water pre-cooling heat exchanger located on a top of said water distributor and cooling recycling water to avoid heating; and d) a wind system providing an air flow blowing over the surface of said streamline tubes for speeding water evaporation on the plurality of streamline cross sectional tubes.
