The utility model will incide the outer wall of the outer sunlight convergence reflex of transparent air layer inner storing water case profile to storage tank by spill optically focused reflector is set, and increase effective daylighting area greatly, and simultaneously, transparent insulating layer also provides a good heat-retaining condition.Therefore, the utility model had both improved the hot property of existing general solar water heater, improved endothermic effect, was easy to again produce, and was economical and practical, was beneficial to enlarge the solar thermal applications field.
The utility model also is provided with fin outside storage tank, this fin surface is coated with the solar selective heat-absorbing film.Can further increase endotherm area by fin, for more thermal energy is provided in the storage tank.
Transparent insulating layer described in the utility model comprises the layer of transparent plate and is strip or latticed transparent body of wall that this transparent body of wall is connected near on the inboard transparent panel; The strip of transparent body of wall is straight line strip or curve strip; The grid of described transparent body of wall is regular hexagon or rectangle or rhombus or triangle.Cross-ventilation speed when having slowed down by transparent body of wall that heat upwards distributes in the storage tank, and then increased heat insulation effect.
Transparent insulating layer described in the utility model comprises two-layer at least transparent panel, between adjacent clear panel, connect be strip, the space can be separated into the transparent body of wall of the areola of strip one by one, reach better heat insulation effect.
Be further to strengthen heat insulation effect, can be by also connecting the transparent body of wall that another group is strip at the outer surface of the transparent panel of close storage tank, described strip is vertical element or curved line.
Described transparent insulating layer be transparent material make be tabular foams, countless fine cavitys further improve heat insulating effect in the foams.
In addition, for increasing daylighting area, the utility model also can be provided with transparent insulating layer on surface, storage tank both ends, and storage tank two ends outer surface also is provided with the solar selective heat-absorbing film.
Spill optically focused reflector of the present utility model can be the spill reflectance coating that directly is arranged in heat insulating stuffing layer upper surface, the reflecting plate that also can be concave arc for section, be arranged in heat insulating stuffing layer upper surface, reflecting plate is the optically focused reflecting surface towards the cancave cambered surface of storage tank.By spill optically focused reflector the outer wall of the outer sunlight convergence reflex of air layer inner storing water case profile to storage tank advanced in transmission, increased the sunlight heat-absorbent surface greatly.
