Summary of the invention
The present invention is in order to solve weak point of the prior art, and a kind of cheap, water curtain type plate solar collector that the solar energy utilization ratio is high is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: water curtain type plate solar collector, comprise framework, heat-collecting plate core and euphotic cover plate, base of frame is provided with the insulation layer, heat-collecting plate core is located at framework in insulation layer top, euphotic cover plate is located at frame roof, heat-collecting plate core comprises that the medium inlet pipe and the medium that be arranged in parallel go out pipe, described medium inlet pipe and medium go out parallel backboard and the panel that is provided with corrosion-resistant and high-temperature resistant between the pipe, backboard is connected with the panel both sides, forms periphery seal between backboard and the panel, the curtain formula medium heat-absorbing chamber of hollow goes out pipe with medium inlet pipe and medium respectively and is communicated with.
Distance between described backboard and the panel is 0.5~4mm, backboard goes out the line segment or the whole piece die mould of pipe at least perpendicular to medium inlet pipe and medium with all corresponding inwardly compacting of panel surface, backboard and panel connect as one by the die mould bottom, and medium inlet pipe, medium go out on pipe and the panel to be equipped with the sunshine absorber coatings.
Distance between described backboard and the panel is 0.5~4mm, several grooves of the corresponding inwardly compacting of backboard and panel surface, and backboard and panel connect as one by bottom portion of groove, and medium inlet pipe, medium go out on pipe and the panel to be equipped with the sunshine absorber coatings.
Described insulation layer is an expanded material, and heat-collecting plate core is connected with frame fixation by expanded material.
Adopt technique scheme, can reach following beneficial effect:
1, be full of heat-absorbing medium in the curtain formula medium heat-absorbing chamber, solar irradiation is mapped on the panel of corrosion-resistant and high-temperature resistant, and luminous energy is converted into thermal energy transfer and gives heat-absorbing medium, photo-thermal exchange efficiency height, backboard and panel can adopt the thin skin stainless steel material, and low cost of manufacture, price are cheap naturally.
2, the distance between backboard and the panel is 0.5~4mm, and heat-absorbing medium has only very thin one deck in curtain formula medium heat-absorbing chamber, and the photo-thermal exchange efficiency can be higher like this; Backboard and panel are welded as a whole by line segment, whole piece die mould or bottom portion of groove, this guarantees that not only act formula medium heat-absorbing chamber goes out being communicated with of pipe with medium inlet pipe and medium, and can strengthen backboard and panel goes out the intensity that is connected between the pipe with medium inlet pipe and medium, prevent that the medium expanded by heating from producing tension force and damaging backboard and panel.
3, heat-collecting plate core is connected with frame fixation by expanded material, and is not only in light weight, also fixed.
The present invention is reasonable in design, simple structure, light and handy durable, cheap, solar energy utilization ratio height, is easy to apply, and can produce long-term economic and social benefit.
