Abstract
A solar heat collector assembly includes a cylindrical transparent tube having an open end portion hermetically sealed by the use of a sealant and being held in vacuum state and a heat-collecting pipe secured in the transparent tube with its end portion extending outside the transparent tube through the sealant. The sealant of a transparent material, for example, is bowl-shaped and the heat-collecting pipe is secured to pass through the center of the bowl-shaped sealant. The pipe and the sealant are bonded together through the use of a proper adhesive metal material. The outer periphery of the sealant is further bonded to the open end portion of the transparent tube. The adhesive metal material is typically 426 alloy.
