Corrugated vacuum glass plate and solar water heater manufactured by same

A corrugated vacuum glass plate is formed by buckling a first corrugated glass plate (1a) and a second corrugated glass plate (1b) which are the same in shape, the peripheries of the first corrugatedglass plate (1a) and the second corrugated glass plate (1b) are melted and sealed, semicircular groove openings in the two plates are spliced pairwise to form a plurality of tubular bodies with two closed ends and vacuumized, and the plate wall is thin, light, light in weight, light in transmission, good in heat preservation and wide in application. A solar water heater made of a corrugated vacuumglass plate is characterized in that the sunward side of a metal water tank (2) is coated with a heat absorption layer and covered with the corrugated vacuum glass plate (1), the other sides of the metal water tank (2) are covered with a heat preservation layer (6) and a heat preservation layer shell (7), and the metal water tank is connected with a water inlet and outlet pipe (4) and an overflowpipe (5).
