A spiral passage chemical converter-heat exchanger formed by a cross-sectionally rectangular housing containing a pair of rows each having a plurality of side-by-side passages. The rectangular housing is wound into a spiral with the inner-most row forming inlet passages and the outermost row forming outlet passages. Thermal contact exists between inflow passages and outflow passages. The outer end of the spiral is connected with an inlet and an outlet. The inlet joins the innermost row of passages and the outlet joins the outermost row of passages. The inner end of the spiral is capped, with a common wall separating the upper and lower passages slotted so that fluid flows from the inlet passages to the outlet passages. As can be seen when the structure is in a spiral, the inlet passages are between the outlet passages with the outlet passages the outer exposed surface of the spiral and the inlet passages forming the surface of the opening through the spiral at the center. A concave sunlight reflector will focus sunlight into the central opening of the spiral thereby heating the fluid in the inlet passages.
