Solar heat collecting units
A solar heat collecting plate as part of an assemblage of the plates is adapted to be used in a solar heat collector for solar furnaces and the like and is designed so that the solar collector can be oriented at any angle relative to the angle of the sun. Several embodiments of the heat collecting plate are disclosed but principally each includes an inner plate portion adapted to protrude generally perpendicularly away from a back support wall of the solar collector and an outer plate portion forming an obtuse angle from the outer edge of the inner plate portion. One surface of the outer plate portion is reflective to solar radiation while the other surface of the outer plate portion and both surfaces of the inner plate portion and the back wall of the solar collector are absorptive of solar radiation. When the collecting plates are assembled on the back support wall of the solar collector in spaced parallel relationship, solar radiation is trapped either within or between adjacent collecting plates virtually eliminating radiative losses from the solar collector. In one embodiment, the outer plate portion is pivotally connected to the inner plate portion to selectively optimize the capture of the solar radiation dependent upon the angle of the sun.
