Abstract:
A high efficiency heat exchanger for a medium condenser comprising:a plurality of parallel vertical cooling fins evenly spaced and having extra length extending both upwardly and downwardly from an ordinary portion of said cooling fins forming an upside additional cooling zone and a downside additional cooling zone; a plurality of medium coil sets connected in parallel and laterally bored through said ordinary portion of said cooling fins; a drip-drop type water feeding box of an evaporative water supply system located over a top of said cooling fins for feeding water densely drop by drop onto a top edge of said cooling fins; and a fan system to deliver wind passing between said cooling fins for speeding the evaporation of evaporative water and blowing off heat and evaporated steam wherein said evaporative water supply system includes a residual water collecting channel, a water reservoir, a water pump, and a water coil, wherein said water coil pierces through said upside additional cooling zone of said cooling zone fins for cooling evaporative water before being guided to said feeding box.
