The specific embodiment
CO as shown in Figure 1
2The cellular canopy-type efficient heat-collecting of filling device structural representation comprises shell 4, heat-insulation layer 3, carbon dioxide filled honeycomb shape cover plate 2, endothermic tube 1, and carbon dioxide filled honeycomb shape cover plate 2 is above endothermic tube 1, and the both is in heat-insulation layer 3.
Carbon dioxide filled honeycomb shape cover plate schematic diagram as shown in Figure 2, comprise peripheral transparent organic glass dividing plate 5, last transparent organic glass cover plate 6, column type lucite short tube 7, following transparent organic glass cover plate 8, also charge into carbon dioxide 12 between the inner short tube of cover plate and the short tube.
Column type lucite short tube 7 schematic diagrames comprise transparent organic glass convex lens 9, column type lucite sleeve pipe 10, carbon dioxide 11 as shown in Figure 3.
The course of work of this heat collector is as follows:
At first sunray shines on the carbon dioxide filled honeycomb shape cover plate 2, and 9 pairs of sunshines of the transparent organic glass convex lens on the cover plate carry out optically focused, and the light behind the optically focused shines on the endothermic tube 1, thereby obtains the lifting of endothermic tube 1 temperature.Carbon dioxide 11 in the column type lucite short tube 7 and the carbon dioxide 12 of cover plate inside and heat-insulation layer 3 all play insulation effect, thereby improve the utilization ratio to solar energy.
One, adopts the cellular cover plate of double-layer seal, this is can reduce effectively by convection current and radiation-induced heat loss according to network, the cylindrical lucite short tube of several sustained heights is stacked in employing in the high printing opacity lucite of bilayer, to reduce the disturbance of gas.When not having cylindrical lucite short tube in the cover plate, upper cover plate receives when shining upon and can heat the cover plate gas inside, the temperature of gas will raise, and the gas temperature of each position is different, disturbance can take place in the cover plate gas inside like this, and its coefficient of heat transfer of convection current takes place gas one will increase, and the heat that cover plate distributes to the outside also increases thereupon, be unfavorable for that heat collector to the absorption of solar energy, has reduced the utilization ratio to solar energy.And when the cylindrical lucite short tube of several sustained heights has been stacked in cover plate inside, short tube just becomes a lot of little gas cell of isolating mutually to gas partitions, when sunlight sees through, can suppress the natural disturbance of gas effectively, thereby play the effect of " thermal diode ", reduce the heat that cover plate externally distributes, improved the utilization ratio of heat collector to solar energy.
Two, in seal cover board, charge into CO
2Isothermal chamber type gas replaces air, and the heat absorption through endothermic tube after sunshine is by glass cover-plate becomes long wave by shortwave, CO
2Gas can stop the sunshine long wave to reflect, and reduces the reflection loss of sunshine, simultaneously CO
2Gas has insulation effect, can improve the heat collector temperature inside, strengthens the heat-absorbing action of heat sink, thereby improves heat collector to the utilization ratio of solar energy.
Three, each small cylindrical lucite short tube upper strata is with the convex lens sealing, and convex lens carry out optically focused to sunshine, thereby improves the utilization ratio to solar energy.
This CO
2The high efficiency solar heat collector of the cellular cover plate of filling has been made model in experiment, and has finished performance and efficiency test.The height of cover plate is 30mm, and mainly by the forming with a protruding clear glass and a lot of cylindrical lucite short tube of one flat plate, inside has been full of CO for it
2Gas.The cylindrical lucite short tube of several sustained heights of stacking in the double-deck high printing opacity lucite has stoped the disturbance of gas effectively, has reduced the heat that cover plate externally distributes, and has improved the utilization ratio of heat collector to solar energy.The wall thickness of cylindrical lucite short tube is 2～3mm, and its interior diameter is 30mm, and adjacent two cylindrical lucite short tubes can keep the distance of 20～30mm, thereby the quantity that can reduce the lucite short tube like this reduces cost.Be with convex lens it to be sealed above each cylindrical lucite short tube, its inside charges into CO
2Gas, and to keep its sealing.
At current social high speed development, under the situation that the energy sharply reduces, utilize pollution-free, inexhaustible solar energy, and the utilization ratio that improves solar energy is the effective measures that we solve energy crisis.The CO that the present invention relates to
2Than ordinary solar heat collector height, and cost is low to the utilization ratio of solar energy for the high efficiency solar heat collector of the cellular cover plate of filling, and the scope of application is extensive.When being used for solar water heater, be applicable to that vast average family uses, economical and practical.Its application market prospect is very optimistic, has very big market value.
