<p>A solar water heater comprises a shell (1) and a heat absorption water tank (2) fixed in the shell (l). A water inlet (3) and a water outlet (4) are disposed on the heat absorption water tank (2). A thermal insulation layer (5) is filled below the heat absorption water tank (2) and above the shell (l), and a transparent thermal insulation board (6) is covered on the heat absorption water tank (2). The heat absorption water tank (2) comprises multiple parallel transverse tubes (21) and multiple parallel longitudinal tubes (22). The transverse tubes (21) and the longitudinal tubes (22) are arranged on the same plane and in communication with one another. Ribs (24) are connected between outer walls of the adjacent transverse tubes (21) or between outer walls of the adjacent longitudinal tubes (22). The heat absorption water tank (2) is made of a plastic material, has the advantages of producing no water scales, anticorrosion, taking up a small space, having a simple structure, and having a low cost, and is especially applicable in areas with high average temperature.</p> |
