Adopt technique scheme, can reach following beneficial effect:

1, the utility model is hung outside the body of wall on the sunny side of building, do not take up space and be not afraid of aerial junk, security is good, be full of heat-absorbing medium in the medium heat-absorbing chamber, because the plate core outside plate of heat-collecting plate core and the structure that plate in-core plate is wave or polyline shaped, the light of sunshine is basically perpendicular to the plate core outside plate that a plurality of inclined-planes are formed by stacking, can reach best endothermic effect like this, luminous energy is converted into thermal energy transfer and gives heat-absorbing medium, photo-thermal exchange efficiency height, plate core outside plate and plate in-core plate can adopt the thin skin stainless steel material, and low cost of manufacture, price are cheap naturally.

2, expand after medium absorbs heat, medium may be compressed in the harmomegathus buffer, and the harmomegathus buffer plays good cushioning effect, can prevent the medium volumetric expansion like this and makes plate core outside plate and plate in-core plate deformed damaged.

3, the distance between plate core outside plate and the plate in-core plate is 0.5～4mm, and heat-absorbing medium has only very thin one deck in the medium heat-absorbing chamber, and the photo-thermal exchange efficiency can be higher like this; Plate core outside plate and plate in-core plate are welded as a whole by the die mould or the bottom portion of groove of line segment shape, whole piece shape, point-like, this guarantees that not only the medium heat-absorbing chamber goes out being communicated with of pipe with medium inlet pipe and medium, and can stiffener core outside plate and plate in-core plate go 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 plate core outside plate and plate in-core plate.

The utility model is reasonable in design, simple structure, lightly durable, cheap, solar energy utilization ratio height, be convenient to install, security is good, is applicable to numerous domestic consumers, is easy to apply, and can produce long-term economic and social benefit.
