Window-type solar water heater

Abstract

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.

Description

technical field [0001] The invention relates to a window-type solar water heater integrated with a building, and belongs to the technical field of solar thermal utilization and building integration. Background technique [0002] The heat collector of the existing flat-panel solar water heater is composed of a back plate, an insulating material, a solar heat collecting plate core, a glass panel and an outer frame combining the above components. In order to save energy and keep warm, high-rise buildings in northern China generally set up window sills of 80-90 cm. The water heater is installed by fixing the collector on a triangular metal frame, and then fixing the metal frame under the window sill on the sunny facade of the building and outside the bay window of the balcony. This installation method firstly destroys the appearance of the building; secondly, it protrudes from the outside of the building. In weather such as strong wind and hail, it is very easy to cause accident...

AI Technical Summary

Problems solved by technology

This installation method first destroys the appearance of the building; second, it protrudes from the outside of the building. In the event of strong winds, hail and other weather, it is very easy to cause damage, fall and other accidents, which is an inherent safety hazard

For this reason, most properties refuse to install, hindering the popularization of solar water heating technology
