Description
- 1. Technical Field
- The present disclosure relates to a device which gathers solar energy.
- 2. Description of Related Art
- In typical solar energy gathering devices, a solar cell panel or a heat gathering pipe is used. No matter which component is used, a total of gathered solar energy is determined by a surface area of the component exposed to light, which can increase the cost of the solar cell panel or the heat gathering pipe.
- What is needed, therefore, is a solar energy gathering device, which can overcome the above shortcomings.
- Many aspects of the present solar energy gathering device can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present solar energy gathering device. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is a schematic plan view of a solar energy gathering device in accordance with an embodiment. -
FIG. 2 is a cross sectional view of the solar energy gathering device ofFIG. 1 taken line II-II. - Embodiments of the present solar energy gathering device will now be described in detail below and with reference to the drawings.
- Referring to
FIGS. 1 and 2 , a solarenergy gathering device 100 includes aheat storage unit 10, a plurality ofheat gathering units 20 thermally connected to theheat storage unit 10, and a plurality of Fresnellenses 30 located on theheat gathering units 20. - Each of the
heat gathering units 20 includes aglass block 24 and aheat pipe 22. Each of theglass blocks 24 has avacuum receiving space 248 receiving theheat pipe 22 therein. In the present embodiment, a shape and a size of thevacuum receiving space 248 are substantially adapted for those of theheat pipe 22. In other embodiments, thevacuum receiving space 248 can be a little greater than theheat pipe 22. Thevacuum receiving space 248 helps heat preservation for theheat pipe 22. Theglass block 24 is transparent to light. In the present embodiment, atop surface 249 of theglass block 24 is flat. In other embodiments, thetop surface 249 of theglass block 24 can be in other shapes, for example, theglass block 24 is a in an elongated pipe shape, and thetop surface 249 can be a cylindrical outer surface. - Each of the
heat pipes 22 includes amain body 228 and a plurality ofspherical knobs 226 extending from themain body 228 and in communication with themain body 228. Themain body 228 is divided into a plurality of sections by thespherical knobs 226. An inner diameter of each of thespherical knobs 226 is greater than that of themain body 228. Theheat pipe 22 is made of a thermal conductive metallic material, such as stainless steel, aluminium (Al), copper (Cu) and alloy of aluminium and copper. Theheat pipe 22 can contain afluid 28 therein. Adistal end 222 of theheat pipe 22 is in contact with theheat storage unit 10 for transferring heat to theheat storage unit 10. In order to be better thermal contact, a heatconductive glue 26 is applied to an interface between thedistal end 222 of theheat pipe 22 and theheat storage unit 10. - Each of the Fresnel
lenses 30 includes aflat bottom surface 32 attached to thetop surface 249 of one of theglass blocks 24, and alight incident surface 34 facing upwards. Thelight incident surface 34 has a plurality of concentric annular protrusions, and heights of the concentric annular protrusions are gradually increased in direction away from a center of thelight incident surface 34. A focal point of each of the Fresnellenses 30 is located at one of the respectivespherical knobs 226. Preferably, the focal point of each of the Fresnellenses 30 is located at a central line of thespherical knobs 226. As theglass block 24 is transparent, the Fresnellenses 30 can converge light to the respectivespherical knobs 226, such that theheat pipes 22 can receive solar energy, and thereby theheat pipes 22 are heated, then theheat pipes 22 can transfer the heat to theheat storage unit 10. - The
spherical knobs 226 provide more space for receiving solar energy gathered by the Fresnellenses 30. Other sections of thetop surface 249 of theglass block 24, not having the Fresnellenses 30, can directly receive solar light, and the solar light can reach theheat pipes 22 either through theglass block 24. No matter how small theheat pipes 22 are, all of the solar energy can be gathered to theheat pipes 22. - The
heat storage unit 10 can be connected to a user's house. - It is understood that the above-described embodiments are intended to illustrate rather than limit the disclosure. Variations may be made to the embodiments and methods without departing from the spirit of the disclosure. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the disclosure.
