A solar heat collector utilizing an elongated vertical mast to support a rectangular parabolic reflector and a transparent cover. The mast is located at the focal point of the parabolic reflector, and the fluid to be heated enters the unit at the bottom, is partially heated as it rises by convection, enters the mast at the upper portion thereof, and is transported downward while being further heated due to the mast focal point location. The unit is rotatable about the mast to maximize heat transfer.

Solar energy collecting apparatus comprising: a solar collector including a parabolic reflector supported on a vertical mast, the mast being hollow and extending along the focal axis of the reflector to heat fluid within the mast; an enclosure for the parabolic reflector including at least a portion of a right circular cylinder having its axis aligned with the focal axis of the reflector and defining, with said reflector, a chamber for the flow of fluid vertically along the reflector outside the mast; upper and lower covers connected with the chamber to close the ends thereof; and means for directing the flow of fluid upward through the chamber and returning through the mast, comprising an opening in the lower cover communicating with the chamber outside the mast, an opening in the mast adjacent the upper end thereof within the chamber, and an opening in the mast at the lower end thereof outside the collector, the opening being effective to permit the flow of fluid through the collector as it is heated initially in said chamber during upward flow and subsequently in said mast during return flow.
