Abstract
The utility model discloses a vacuum no-coating flat-plate solar collector integrated with a building. Two layers of main glass panels and four peripheral side strips form a sealed cavity, both the main glass panels are double-layer vacuum glass plates, a plurality of separation plates are vertically arranged between the two layers of main glass panels, the hollow cavity in the sealed cavity is separated into a plurality of fluid channels by the separation plates, an inlet and an outlet communicated with the fluid channels are arranged on side edges of the sealed cavity, the sealed cavity is filled with Cu/ ethylene glycol nanometer fluid black liquor as a medium for adsorbing solar radiation energy directly. The fluid channels in the sealed cavity are connected end to end to form serial runners between the inlet and the outlet. The heat efficiency is high, no coating is required, the large area assembly is convenient, the vacuum no-coating flat-plate solar collector can be used as a single solar heat collector or as a component used directly on the building, and the integration with the building is realized.
Description
Technical field
The utility model relates to a kind of heat collector, and particularly a kind of and vacuum architecture-integral is exempted from the plated film flat-plate solar collector.
Background technology
In the solar energy utilization technique field, heat collector commonly used at present has:
(1) vacuum glass tube heat collector, owing to be subjected to the restriction of mounting condition and vacuum tube life-span itself, intensity etc., be difficult to realize integrated with building, simultaneously, owing to exist between the vacuum tube than the bassoon distance, the effective collector area of vacuum tube collector only is about 1/2 of a heat collector contour area, so the efficient of heat collector is lower.
(2) flat plate collector, though flat plate collector is realized and architecture-integral easily, the thermal efficiency is low, heat-insulating property is poor but it exists, defectives such as the easy oxidation of coating, copper pipe are perishable are the antifreeze problem that solves flat plate collector, the modes of using anti-icing fluid to adopt secondary heat exchange as cycle fluid that adopt in actual the use more, because the heat-transfer effect of anti-icing fluid is relatively poor, no matter be thermal-arrest or secondary heat exchange, all require a bigger temperature difference, this also increases the heat loss of heat collector undoubtedly.
(3) adopt plated film mode in hollow plate glass, the defective of this mode is a beading temperature height, destroys selective absorbing film, causes Heat-collecting effect to reduce greatly.
More than in all kinds of heat collectors, heat transmission between heat-absorbent surface and the working media all is the indirect heat transmittance process at interface more than, plated film or heat absorbing coating on the heat-absorbent surface are converted to heat energy with solar radiant energy, conduct the heat transferred working media by the heat of solid wall surface then, because there is big thermal resistance in the solid-liquid boundary layer, must exist the bigger temperature difference as heat conducting motive force between heat-absorbent surface and working media, this temperature difference makes the external heat radiation of heat-absorbent surface increase, thereby increased the heat loss of heat collector, bigger thermal resistance also is unfavorable for the heat conduction simultaneously, and the thermal efficiency of therefore above all kinds of heat collectors is not high.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of thermal efficiency height, exempts from plated film, is convenient to the large tracts of land assembling, can be used as building element, has easily realized exempting from the plated film flat-plate solar collector with the vacuum of architecture-integral.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of and vacuum architecture-integral is exempted from the plated film flat-plate solar collector, be characterized in: edge strip is formed airtight cavity around being reached by two-layer main face glass, described main face glass is all the dual-layer vacuum glass plate, between two-layer main face glass, vertically be provided with some dividing plates, cavity in the airtight cavity is divided into some fluid passages by dividing plate, side at airtight cavity is provided with import and the outlet that is connected with above-mentioned fluid passage, is filled with the medium of direct absorption solar radiant energy in airtight cavity.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, the end to end formation in fluid passage in the airtight cavity by import to the serial runner exporting.
The utility model compared with prior art has following beneficial effect:
(1) it is that a kind of vacuum is exempted from plated film vacuum plate heat collection device, has realized exempting from plated film, and production technology is simplified.
(2) reach up and down and adopt hollow plate glass on every side, good heat insulating has reduced the heat loss of heat collector.
(3) be divided into several fluid passages with glass in the middle of the two-layer vacuum glass, the effective collector area of heat collector reached more than 95%, far above present vacuum tube collector.
(4) adopt functional thermal fluid directly to absorb the solar radiation energy, reduced heat transfer resistance, the maximum temperature of heat collector appears at the inside of functional thermal fluid, and experiment shows that its absorptivity to solar radiant energy can reach more than 95%, has also reduced the radiation loss of heat collector simultaneously.
(5) vacuum is exempted from plated film vacuum plate heat collection device and is adopted whole welding mode, intensity is big, can be used as monomer solar thermal collector, solar water heating system use, also can be used as building element and be directly used in glass curtain wall, balcony fence, sunshading board of building roof, building etc., realize easily and architecture-integral, existing heat preservation and soundproof function is convenient to be assembled into large-area solar thermal collection system again.
