Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is explicitly described.Obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the technical scheme that the embodiment in the present invention proposes, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment
As it is shown in figure 1, present embodiment discloses the device of solar generating that a kind of generating efficiency is high, including the solar panel 10 arranged from top to bottom and heat collecting sheet 20.Being provided with solar panel output interface 11 on solar panel 10, at the heat pipe 30 flowed for liquid being arranged below two ends connection of heat collecting sheet 20, heat pipe 30 is close to heat collecting sheet 20 and is arranged.
The heat collecting sheet 20 that solar panel 10 is arranged below mainly collects the heat energy that the heat energy of solar energy produces with solar panel 10, the heat energy of cell panel 10 is collected, the heat on heat collecting sheet 20 is taken away by the flowing of liquid in heat pipe 30, thus reducing the operating temperature of solar panel 10, reach to improve the effect of solar panel 10 generating efficiency, compared to passing through to increase the cooling methods such as air circulation, spray, do not result in the waste of resource.As shown in Figure 2, when solar irradiation is sufficient, the operating temperature of solar panel 10 is more low, and its operating power is more high, and the electricity namely sent is more big.
Additionally, this TRT can be used alone, no matter the output interface 11 of cell panel or the two ends of heat pipe 30 can and another TRT between can be interconnected, combination in series or in parallel can also be adopted between multiple TRTs, realize modularity generating, when an assembly goes wrong, properly functioning without influence on other assemblies, construction, run, in maintenance very simple and convenient.
Simultaneously, in heat pipe 30, the liquid of flowing can be water or the bigger liquid of other thermal capacity, and owing to the heat capacity ratio of water is big, its cooling-down effect is better, and source is relatively wide, adopts the heat-conducting liquid using water as the interior flowing of heat pipe 30 and be capable of modular hot water supply system.The two ends of heat pipe 30 are respectively water inlet 31 and outlet 32, and are respectively arranged with the valve 33 for controlling water velocity.Water flows in heat pipe 30 from water inlet 31, and the heat on heat collecting sheet 20 is conducted to water by heat pipe 30, and water flows out and take out of the heat that solar panel 10 sends, in the process by the waste-heat water of solar electrical energy generation.Compared to traditional solar water heater, hot water will not being made to seethe with excitement, the temperature of hot water can control by organizing the series, parallel of this hot water supply system more.And water temperature can be controlled by water velocity, when needing to produce the relatively low hot water of temperature, control valve 33 and increase water velocity, otherwise control valve 33 and reduce water velocity.
In order to improve the heat transfer efficiency of heat collecting sheet 20 further, making for matter soft material matter at heat collecting sheet 20, the outer surface of heat pipe 30 and heat collecting sheet 20 fit tightly so that heat pipe 30 and heat collecting sheet 20 can embed in heat collecting sheet 20 after fitting tightly.The roundabout lower section being laid on heat collecting sheet 20 of heat pipe 30 simultaneously, for instance heat pipe 30 is layed in the lower section of heat collecting sheet 20, and forms snake pipe, or form spiral pipe, or form other shapes can being fully contacted with heat collecting sheet.Adopt above-mentioned heat collecting sheet 20 and heat pipe 30 structure can improve the contact area of heat pipe 30 and heat collecting sheet 20, and then improve the heat-conducting effect of heat pipe 30.
In order to improve the service life of TRT, between solar panel 10 and heat collecting sheet 20, it is provided with the division board 40 that heat-conducting is made.Division board 40 acts primarily as the effect of sealing, isolation steam, it is prevented that in use solar panel 10 is caused damage by moisture, it is prevented that owing to the effect of steam causes electrical system short circuit.
Additionally there is metal framework 50 in solar panel 10, division board 40 and heat collecting sheet 20 arranged outside.Metal framework 50 is the external boundary of TRT, the two ends of heat pipe 30, and namely intake-outlet all adopts the mode being spirally connected or welding to be fixed on the side of metal framework, and intake-outlet can have multiple.Metal framework 50 acts primarily as the effect of sealing, isolation and ground connection, the safety of TRT is ensured, safety mainly comprises two aspects: one, owing to there is the voltage more than 36V in solar power system, metal framework 50 can carry out metal with the support of solar panel or base and be connected, and the safety of construction, operation maintenance personnel is ensured；Two, when there is hot water leak, the personnel of not resulting in such as are burned at the ill effect.
Embodiments described above, is not intended that the restriction to this technical scheme protection domain.The amendment made within any spirit at above-mentioned embodiment and principle, equivalent replacement and improvement etc., should be included within the protection domain of this technical scheme.
