Abstract: A heat exchanger device for use with a solar energy system comprising at least one pair of substantially parallel enlarged heat exchange inlet conduits operatively coupled together within a fluid storage tank to receive heated fluid from an external source to heat fluid within the storage tank and a reduced outlet conduit coupled to the lower portion of the substantially parallel enlarged heat exchange inlet conduits to remove the fluid from the fluid storage tank.

Abstract: A solar energy collector for heating liquids such as water through absorption of the sun's energy. The solar energy collector comprising an enclosure structured to operatively house at least a pair of serpentine fluid conduits disposed in substantially parallel relationship relative to each other. The enclosure comprises a frame configured to operatively support a substantially transparent medium in parallel spaced relation relative to the pair of serpentine fluid conduits to intensify the sun's rays and a reflective back member in parallel spaced relation relative to the pair of serpentine fluid conduits on the opposite side from the substantially transparent medium.
