Description

A ground reflective solar water heater

technical field

The utility model relates to the technical field of solar water heaters, in particular to a ground reflection solar water heater.

Background technique

At present, the reflectors of solar water heaters on the market keep the same angle with the vacuum heat collecting tubes, and the distance between them and the vacuum heat collecting tubes is relatively close, so firstly, when the sun rises in the morning and when the sun sets in the afternoon, the plane of light and the plane of the vacuum heat collecting tubes are clamped. The absolute value of the angle is very small or almost zero. At this time, the individual heat collecting tubes close to the sunlight are heated by radiation, and the rest of the vacuum heat collecting tubes are not radiated. At this time, the function of the reflector completely disappears, and on the contrary, it also blocks the light plane. The part that is parallel to the plane of the vacuum heat collecting tube or has a negative angle is illuminated by sunlight from the side or back of the vacuum heat collecting tube, which undoubtedly reduces the heat collection efficiency of the solar water heater. In addition, the reflector is close to the vacuum heat collecting tube and forms a certain angle with the horizontal plane , blocks the flow of airflow, and constitutes a certain threat to the fixation of the solar energy and the surrounding safety, especially when the water tank is empty or the water volume is small, it is easy to fall from the roof of the building under the action of wind and cause certain damage.
