Fig. 3 is embodiment 2 structural representations of a kind of vacuum flat solar energy heat collector that is made of 4 collector arrays of the present utility model.
The specific embodiment
The vacuum flat solar energy heat collector of the utility model design reaches embodiment in conjunction with the accompanying drawings and is described in detail as follows:
The heat collector of heat collector of the present utility model for constituting by two flat inside and outside casings that are nested together, connect with grid muscle sheet network between the inside and outside casing of this heat collector, this grid muscle sheet is provided with through hole (two spaces between the casing are connected), end in outer case is provided with a valve that can vacuumize, by vacuumizing valve, air between two casings is extracted out, formed vacuum layer; Also be respectively equipped with the outlet pipe interface and the water inlet pipe interface of straight-through internal box at the upper and lower end face of this heat collector; The front panel of this outer case is a clear sheet, and the outer surface of the relative panel of corresponding internal box scribbles gradual change aluminium nitrogen aluminium film.
The concrete size of heat collector of the present utility model can be determined its long, high, thick size according to actual needs.
For example generally be long 1200-2000 millimeter, high 1000-2000 millimeter, thick 100-200 millimeter, wall thickness is decided according to material.
The width of grid muscle sheet is decided according to the space between the interior outer case, for example is generally the 10-50 millimeter; Thickness is decided according to material therefor, for example is generally the 0.5-2 millimeter.
According to the size of water consumption, can increase or reduce box sizes, if box sizes strengthens or dwindles the also corresponding change of the size of its grid muscle sheet.Be more preferably and adopt a plurality of heat collectors to make up arbitrarily, form plate configuration heat collector.Increased the flexibility that product uses.
The function of this device each several part is respectively described below;
Grid muscle sheet network of the present utility model had both played the effect of fixing two box locations, had reinforced bulk strength again, and especially its fastness is stronger when vacuum forms.The wall thickness and the material of outer case in the rare close degree of grid muscle sheet network is decided by, if inside and outside casing wall thickness is thin or material is relatively poor, intensity a little less than, then can encrypt grid muscle sheet network; If inside and outside casing wall thickness is thicker or material is better, intensity is stronger, then can be with sparse grid muscle sheet network.
Grid muscle sheet network can pass through mould process with being connected of interior outer case, and one-shot forming also can be processed molding bonded respectively; Grid muscle slice graticule is the form of bar intersection anyhow, also can only establish horizontal stripe or vertical bar, and the shape and the size of the through hole on the grid muscle sheet are not limit, as long as there is enough intensity to make two faces of its support indeformable under vacuum condition.
The front panel of outer case is made with transparent material, as glass or lucite.Make light to penetrate like this and arrive the internal box top layer.The outside of the case face of internal box correspondence scribbles gradual change aluminium nitrogen aluminium film.After light arrived this aspect, endothermic effect increased, and heat radiation reduces.Simultaneously, because gradual change aluminium nitrogen aluminium film is to be coated in the internal box outside, do not influence the water quality of internal box the inside.
Outer case can be made with a kind of material of material, as glass or lucite; Also can make with the material of two kinds of materials, as the glass or the poly (methyl methacrylate) plate of front panel employing printing opacity, other panel adopts opaque stainless steel or plastic plate; Such technology is very ripe.The material of internal box is that a kind of material is made, and adopts stainless steel or plastic plate.
There is a water inlet interface device lower end, and cold water is from entering inner water tank here.There is an outlet coupling device upper end, and hot water is from output here.In the internal box, behind the heat energy of water through the transform light energy Cheng Shui of solar energy, the temperature of water improves, and the water of heat begins up to flow, and the circulation that brings out hot water on the cold water is advanced in so automatic formation lower end.Again this heat collector is connected with water tank, thereby reaches the purpose that improves constantly the water tank water temperature.
