In the such scheme, be filled with layer of inert between said panel and the base plate.Like this, can reduce heat energy, make the water better heat preservation in endothermic tube, feed tube and the drain pipe the scattering and disappearing of panel and base plate.
In the such scheme, the inner bottom plating of said base plate and Outer Bottom Plating are sinkage type structure, and the bottom surface of said base plate is a slab construction, and the inner bottom plating of said base plate and the surface of Outer Bottom Plating are provided with reinforcement.Like this, can increase the intensity of inner bottom plating and Outer Bottom Plating.
Preferably, the inner bottom plating of said formation cavity and the distance between the Outer Bottom Plating are 5~20mm.
In the such scheme, be tightly connected through first seal between the inner bottom plating upper surface of said base plate periphery and the lower surface of panel.Like this, can increase the sealing between panel and the base plate, make heat insulating ability better.
Preferably, the inboard of said frame is provided with groove, and the card of said panel and base plate and is tightly connected with the upper surface of panel and the Outer Bottom Plating lower surface of base plate respectively through second seal in the groove of frame.
In the such scheme, said inner bottom plating periphery is provided with keeper, and the zone that said keeper surrounded is corresponding with the plane sizes of panel.Like this, fix the position of panel on inner bottom plating through keeper.
Preferably, said panel is an armorplate glass, and said feed tube, drain pipe and endothermic tube are copper pipe.
Preferably, said base plate is that monoblock type or split are spliced.
Beneficial effect of the present invention is: adopts the base plate of double-layer plastic structure, can make the heat collector heat-energy losses little, and better heat preservation, solar energy utilization rate is higher.Utilize filling with inert gas formation heat-insulation layer between panel and the base plate, not only avoid heat-preservation cotton to be dispersed in the face glass, and can reduce the rate of heat dissipation of heat collector.In addition, the seal of panel and base plate periphery can prevent effectively that hot-air is difficult for leaking, and improves solar energy utilization rate.
