ABSTRACT:
A fluted strip of heat conducting material is spirally wound edgewise about a length of pipe and, in combination, define a heat exchanger for receiving solar energy. The lateral edges of the flutes forming the outer edge of the strip define an undulating line superimposed upon a helix. The lateral edges of the flutes forming the inner edge of the strip define an undulating line superimposed upon a sinusoidal curve which, in turn, is superimposed upon a helix. Thereby, cyclically repetitive ones of the flutes become oriented normal to the rays of the sun to effect maximum heat transfer as the angle of incidence to the heat exchanger varies. A method for producing the heat exchanger is also described.
