Portable solar heating structure

This creation is about a solar heater, especially a portable solar heating structure that can be used to heat water and cook food when it is outdoors or when there is no electricity, and is light and portable.

Solar energy is a kind of renewable energy, which can be used for power generation through photoelectric conversion, or used for heating, water treatment, cooking and heat exchange through photothermal conversion. The solar water heating system heats water through light heat exchange. The solar water heating system has two kinds of vacuum tube collectors and glass flat plate collectors. The glass flat plate collector is composed of a heat absorbing body, a casing, a transparent cover plate and a heat insulating material, and the sun shines on the glass flat plate collector. When the water in the glass flat plate collector tube is heated, the density becomes small, the hot water rises from the bottom of the glass flat plate collector to the top, flows into the insulated water storage bucket, and the cold water in the lower part of the water storage tank flows into the bottom of the glass flat plate collector, continuously The circulation is carried out to raise the temperature of the water in the entire storage tank.

The middle of the vacuum tube collector is a vacuum layer, and the outer edge of the vacuum layer has a double-layer glass sleeve, wherein the outer glass sleeve is completely transparent, and the inner glass sleeve is coated with a selective absorption film, and the selectivity is transparent. The absorption film absorbs the heat of the solar energy entering the double-layer glass sleeve, and heats the cold water flowing through the inner glass sleeve to become hot water, wherein the vacuum tube collector is provided because the selective absorption film and the vacuum layer have the function of blocking heat loss. The heating effect is better than the glass flat plate collector good.

However, the vacuum tube collector and the glass flat plate collector described above are bulky and heavy, and the vacuum tube and the glass plate are easily broken, so that the vacuum tube collector and the glass flat plate collector can only be placed at a fixed point. It is not easy to move.

In view of the above situation that the solar water heating system can only be set at a fixed point, the creator of the case is unable to move the solar water heating system to the place where it is needed. Therefore, after thinking and improving, and after painstaking research, Finally successfully developed and completed this portable solar heating structure.

The main purpose of the present invention is to provide a portable solar heating structure in which one side of the diaphragm is processed to form a Fresnel lens structure, and the diaphragm can focus sunlight to generate heat.

The second objective of this creation is to provide a portable, lightweight solar heating structure that is portable and lightweight.

Another object of the present invention is to provide a portable solar heating structure that can be used to heat water and cook food outdoors or when there is no electricity.

In order to achieve the above objectives, the portable solar heating structure of the present invention is mainly processed on a surface of a diaphragm to produce a Fresnel lens structure, and the diaphragm is provided with one of Fresnel lens structures facing the water to be heated. The food to be cooked, and the diaphragm has the opposite side of the Fresnel lens structure facing the sun, and the film is fixed by a positioning device, and is irradiated by the sun light and penetrates the diaphragm. The Fresnel lens structure produces a focused heat generating effect that heats or cooks water or food.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 4 is a schematic view showing a second embodiment of a portable solar heating structure according to the present invention; and FIG. 5 is a schematic view showing a third embodiment of the portable solar heating structure.

Referring to Figures 1 to 3, the portable solar heating structure of the present invention mainly comprises a diaphragm 1 and a positioning device 2, wherein the diaphragm 1 is a transparent film made of a polymer, and the present invention is A Fresnel lens structure 11 is formed on one surface of the diaphragm 1, and the four corners or the periphery of the diaphragm 1 are provided for the positioning device 2 to open, suspend or fix the diaphragm 1 and adjust the film. The positioning unit 12 of the sheet 1 and the positioning unit 2 and the positioning unit 12 are configured to be fixedly coupled to each other.

Please refer to FIG. 3 , which is a first embodiment of the present invention. In this embodiment, the positioning unit 12 of the diaphragm 1 is a through hole 121 provided at four corners of the diaphragm 1 , and the positioning device 2 has four respective pairs. The tethers 21 of the perforations 121 should be waited for. When the embodiment is applied, one end of the tethers 21 is respectively bound or hooked on the perforations 121 of the four corners of the diaphragm 1, and the tethers 21 are attached. Relatively binding or hooking the other end of the diaphragm 1 to a columnar support such as a tree or a utility pole (not shown), the diaphragm 1 is opposite to the other side of the Fresnel lens structure 11. Facing the sun, the diaphragm 1 has one side of the Fresnel lens structure 11 facing the water to be heated or the food to be cooked, and the Fresnel lens structure 11 heats and cooks the water at different focus heights and inclination angles. The cooking of the food produces different temperatures. Therefore, in the present embodiment, the diaphragm 1 is adjusted to be perpendicular to the direction of the sun, and the focusing height of the membrane 1 and the food to be heated or the food to be cooked is preferably about 20 cm. Heating effect, while the direct solar radiation (DNI) 1 is 500~600W/m ² , through the Fresnel lens structure 1 1 The generated focusing temperature reaches a high temperature of about 500 degrees, which in turn heats the water and cooks the food.

Referring to FIG. 4 , a second embodiment of the portable solar heating structure of the present invention is provided. In this embodiment, the positioning unit 12 of the diaphragm 1 is a sleeve portion 122 on opposite sides of the diaphragm 1 , and the positioning device is provided. 2 is a second positioning rod 22, the positioning rods 22 are threaded on the sleeve portions 122, and the diaphragm 1 is opened by pulling the two positioning rods 22 apart, and then the diaphragm 1 is relatively Philippine. The other side of the Ner lens structure 11 faces the sun, and the diaphragm 1 has a surface of the Fresnel lens structure 11 facing the water to be heated or the food to be cooked, and then adjusts the angle of the diaphragm 1 to the sun and the film.
