SOLAR HEATER FOR SWIMMING POOLS

摘要

A heat exchanger for warming the water in a swimming pool during the day by means of solar heat and for cooling the water at night consisting of a pair of rectangular sheets of black matte finish flexible film plastic sealed together so as to form a closed perimeter having an inlet passage and an outlet passage, and a sinuous flow path consisting of a plurality of straight parallel elongated flow channels formed between the inlet and the outlet. At a plurality of points along each straight flow channel the two plastic sections are heat sealed together to form obstacles to the straight flow path creating zones of turbulance which enhance the efficiency of the heat exchange. A pump removes pool water from a drain, passes it through a filter and divides the filter output between one flow path back to the pool inlet and another flow path to the heat exchanger using an adjustable flow diverter consisting of a T-section having a movable tube extending up from the leg of the T into the arm.
