Abstract

The present invention provides an energy-saving plate and a method for manufacturing the same. The energy-saving plate of the present invention includes: at least one upper plate, at least one lower plate, at least one inner plate, and a plurality of support structures; a top edge of the upper plate and a bottom edge of the lower plate appear as a straight line; the inner plate is provided between the upper plate and the lower plate, and adjacent plates are separated by the plurality of support structures; an exhausting opening is provided at a lateral side of the inner plate, which is a through-groove inter-penetrating upper and lower surfaces of the inner plate; the periphery of the upper plate, the lower plate, and the inner plate are sealed via a sealing material, so as to form vacuum layers between the plate layers; an exhausting pipe is arranged in the exhausting opening, with which the exhausting opening is sealed together via the sealing material, an open-end of the exhausting pipe is located inside the exhausting opening, and a closed-end of the exhausting pipe is located outside the exhausting opening and is located in the space formed between the upper plate and the lower plate. In the present invention, a total flat surface of the energy-saving plate is achieved without structure defects, thus enhancing the strength of the energy-saving plate.
