A Solar Heat Collector unit having a series of parallel convex metal heat collector interconnected liquid channels, a series of transparent domes in sealed and spaced parallel relationship thereover, and an air suction pump connected with the dome for taking the air from under the dome for creating a vacuum in the space between the dome and the heat collector channel for thereby preventing air convection and conduction within that space and thus preventing loss of solar heat from that space. |

DETAILED DESCRIPTION What is claimed as new and desired to be secured by letters of patent is: 1.
A solar heat collector unit comprising a metal frame, a thick plastic heat insulative material piece formed integral with the frame, a liquid seal sheet means completely covering a side of the insulative material, a single likeshaped metal heat absorber plate means completely covering said seal sheet means and having a plurality of convex formed channels therein with the channels formed on a side thereof opposite from the seal sheet means side and adapted to act as liquid ducts and connected with each other by a convex liquid distribution duct, a single transparent dome member means completely sealingly covering said heat absorber plate means in sealed spaced air relationship thereover, said frame and heat absorber plate means and seal sheet means and dome each having collar means adapted for adjacent abutment so as to be clampingly held thereby together peripherally, a ring washer between the liquid sheet seal means and the heat absorber plate means, a plurality of fastening means extending through the frame and seal sheet means and absorber plate means and dome member and adapted for compressing and holding the collar means of each together in sealed relationship, liquid ducts communicating the interior of said channels with a reservoir, an air tube sealed duct communicating the underside of the transparent member with an air suction pump for providing an air tight connection with the space between the underside of the dome member and the adjacent exterior of said channels with an air suction pump, an operable air suction pump connected with said air tube duct, whereby upon operation the air suction pump a vacuum is created thereby in the scope between the transparent member and the channels of the heat absorber plate means when the fastening means is so sealingly tightened to hold the frame and seal sheet means and metal absorber plate means and dome member sealingly together in tight seal relationship
