Flat plate collector with vacuum interlayer

The utility model relates to a flat plate collector with a vacuum interlayer. The flat plate collector with the vacuum interlayer comprises an aluminum alloy shell, wherein the upper portion of the aluminum alloy shell is open. A heat insulating layer is arranged in an inner layer of the aluminum alloy shell, a double-layer transparent glass cover plate is arranged at the position of an opening of the aluminum alloy shell, the vacuum interlayer is arranged between an upper layer and a lower layer of the double-layer transparent glass cover plate, and a tube-plate type heat absorbing body is arranged below the transparent glass cover plate. According to the flat plate collector with the vacuum interlayer, the large defects of natural convection losses and radiant heat losses existing in a traditional flat plate collector are overcome, radiation losses can be greatly reduced, and conversion efficiency of the collector can be remarkably improved.
