Water curtain type plate solar collector

Technical field

The invention belongs to technical field of solar utilization technique, particularly a kind of water curtain type plate solar collector.

Background technology

Solar energy is as a kind of clean energy resource, is again simultaneously a kind of inexhaustible, nexhaustible energy and being favored by countries in the world, now people utilize solar energy maximum be to obtain hot water.Flat plate collector is as modal a kind of heat collector in the middle of the solar water heater, its structure mainly comprises backboard, heat-insulation layer, heat-collecting plate core and euphotic cover plate, with reference to Fig. 1, Fig. 2, heat-collecting plate core comprises by the medium inlet pipe 31 of some canalis pterygoideus 30 arrangement connections and medium going out to manage 32, canalis pterygoideus 30 is provided with heat absorption fin 33, scribble the sunlight heat absorber coatings above the heat absorption fin 33, the liquid heat-absorbing medium of turing in the canalis pterygoideus 30, solar irradiation is mapped on the fin 33, fin 33 conducts the heat that absorbs to canalis pterygoideus, therefore, canalis pterygoideus 30 and heat absorption fin are made by the copper material or the aluminium of good heat-transfer, and this just makes whole heat collector cost higher, and this structure of canalis pterygoideus arranged outside heat absorption fin makes in the heat transfer process thermal resistance is arranged, thermal loss is bigger, and utilization efficiency of heat energy is lower.Therefore, applying of this solar thermal collector is subjected to significant limitation.

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.
