Abstract
Abstract A solar energy heat exchanger including a housing formed by parabolic shaped walls and a transparent front plate connecting the walls. A longitudinal focal tube is positioned about the focal line of the parabolic housing. The transparent front plate is faced toward the sun, permitting the rays to pass therethrough, some of which pass onto the front part of the focal tube. The inner surface of the parabolic walls reflect the rest of the sun rays which pass into the housing, and send the reflected rays to the back part of the focal tube. A plurality of flow tubes can be positioned adjacent the inner surface of the parabolic walls to receive the sun rays as well. The flow tubes can have reflective coatings around them to aid in reflecting the sun rays on to the focal tube. A top and bottom cover on the parabolic housing have holes therein which are located above and below both the focal tube and the flow tubes, permitting a pipe assembly to connect to the tubes for providing the entry and exit of a fluid into the tubes. The solar energy heat exchanger can be placed inside a dwelling, with the transparent front plate serving as the actual windowpane of a window aperture.
