The invention provides a window-type
solar water heater which comprises a heat collecting box body, a liquid inlet
pipe, a liquid outlet
pipe and a heat preservation water tank. The heat collecting box body comprises a heat collecting chamber formed by inner-layer hollow glass, outer-layer hollow glass and a
peripheral heat preservation framework, guard-bar-
type metal heat collecting pipes are longitudinally arranged in the heat collecting chamber of the heat collecting box body, flow collecting pipes are transversely arranged on the
metal heat collecting pipes up and down, and a liquid inlet connected with the liquid inlet
pipe is formed in the lower flow collecting pipe; a liquid outlet connected with the liquid outlet pipe is formed in the upper flow collecting pipe, the liquid inlet pipe and the liquid outlet pipe are connected with the heat preservation water tank, and the heat preservation water tank is provided with a water using pipe and a water supplementing pipe. The window-type
solar water heater is not installed as independent equipment any longer, but is integrated as part of a building, the
metal heat collecting pipes can simultaneously serve as guard bars of a big
bay window, and the appearance and the installation way of the window-type
solar water heater are same as those of an ordinary window; the window-type solar
water heater is installed on a window while the building is constructed, it is guaranteed that the appearance of the building is unchanged, no protrusion exists on the outer wall of the building, accidents of breaking, dropping and the like are avoided, and the safety is improved.
