Collector pipe for solar water heater

The invention discloses a collector pipe for a solar water heater and relates to the technical field of solar water heaters. According to the collector pipe for the solar water heater, the outer diameter of the collector pipe ranges from 36 mm to 50 mm, the inner wall of the collector pipe is configured to be in a corrugated shape, and the portions, on the apexes of corrugations, of the inner wall are provided with rhombic refracting strips. The inner wall of the collector pipe is plated with a red copper plating layer. Reinforcing ribs evenly distributed on the periphery of the collector pipe are evenly distributed on the outer wall of the collector pipe. The collector pipe for the solar water heater is good in heat collecting performance. 本发明公开了种太阳能热水器的集热管，涉及太阳能热水器技术领域。本发明的太阳能热水器的集热管，所述集热管的外径为36-50mm,所述集热管的内壁设置成波纹状，所述内壁在波纹的顶点处设置菱形折射条；所述集热管的内壁上镀有紫铜镀层；所述集热管的外壁上设置均匀分布在其外周的加强筋。本发明提供了种集热性能好的太阳能热水器的集热管。
