Description

Solar flat plate collector with self-anti-freezing protection function

Technical Field

The utility model relates to a solar flat plate collector technical field, concretely relates to dull and stereotyped heat collector of solar energy with protection function that prevents frostbite of oneself.

Background

The solar energy is inexhaustible and pollution-free huge energy. With the decreasing reserves of coal, oil and gas in the world, the energy crisis is really in front of people, and the use of traditional energy also threatens the natural environment and destroys the ecological balance. Solar energy has therefore been regarded as the best environmentally friendly renewable energy source. With the development of solar energy utilization technology, solar water heating systems (water heaters) have appeared and gradually become important energy conversion equipment for solar energy utilization. Flat-plate solar water heaters in various solar water heating systems (water heaters) have gradually become the mainstream of solar water heating systems (water heaters) due to the advantages of long service life, corrosion resistance, few faults and the like.

Solar water heating systems (water heaters) are installed outdoors and are directly exposed to the attack of wind and rain. In most areas of China, the weather below zero occurs, and under the weather condition, water in a flat-plate solar water heating system (water heater) expands due to freezing volume to damage a circulating pipeline, so that the water heating system (water heater) cannot be normally used due to water leakage.

Therefore, a solar water heating system (water heater) in the market at present cannot directly use water as a circulating medium, only uses a chemical agent (antifreeze) with a low freezing point as the circulating medium in the system, and then sets a jacket or a coil and other heat exchangers in a heat storage water tank to perform secondary heat exchange, so that the problem of pipeline freezing in the solar heat collecting system is solved. This approach has several major drawbacks:

first, because the heat storage water tank uses in the jacket or coil pipe heat exchanger carries out the secondary heat transfer, compare direct heat transfer, the thermal conversion inefficiency, product cost is high.

Secondly, because the used antifreezing solution is chemical (ethylene glycol, glycerol and the like), once the pipeline leaks, the environment is easily polluted, and once the pipeline enters water, the pipeline can cause great damage to human bodies.

Thirdly, the antifreeze is formed by combining a chemical agent and water, the water is evaporated due to high-temperature flow, so that the normal operation of a system is ensured by adding liquid frequently, the subsequent maintenance of products is difficult, the cost is increased, and the antifreeze effect can also be reduced year by year after long-term use and cannot reach the antifreeze effect.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a do not use antifreeze can directly use the solar flat plate collector who has the protection function that prevents frostbite of oneself of medium.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a dull and stereotyped heat collector of solar energy with protection function is prevented frostbite by oneself, includes aluminum alloy frame, high printing opacity glass and metal bottom plate, and the three forms confined space, and its innovation point lies in: transversely set up a plurality of red copper pipelines and vertically set up a pair of red copper pipeline in the aluminum alloy frame, and fore-and-aft red copper pipeline is located both ends about horizontal red copper pipeline respectively, and rather than the intercommunication, set up the silica gel elastomer of bar in the red copper pipeline, the density of silica gel elastomer is 0.5-0.6g/cm³(ii) a Sealing plugs are arranged at the upper end and the lower end of the longitudinal red copper pipeline; and heat absorption aluminum fins are arranged on the surface of the aluminum alloy frame.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Referring to fig. 1-2, a solar flat plate collector with a self-antifreezing protection function comprises an aluminum alloy frame 1, high-transparency glass 2 and a metal bottom plate 3, wherein the aluminum alloy frame 1, the high-transparency glass 2 and the metal bottom plate 3 form a sealed space, a plurality of red copper pipelines 4 are transversely arranged in the aluminum alloy frame, a pair of red copper pipelines 4 are longitudinally arranged in the aluminum alloy frame, the longitudinal red copper pipelines are respectively positioned at the left end and the right end of the transverse red copper pipelines and are communicated with the transverse red copper pipelines, strip-shaped silica gel elastomers 5 are arranged in the red copper pipelines 4, and the density of the silica gel elastomers 5 is 0.5-0.6g/cm³(ii) a The upper end and the lower end of the longitudinal red copper pipeline are both provided with a sealing plug 6; in this embodiment, the surface of the aluminum alloy frame 1 is provided with heat absorbing aluminum fins 7. Specifically, the utility model discloses the realization of function is realized the frostproofing protect function of oneself through the physical mode mainly in red copper pipeline 4 the inside, and the heat-absorbing body divides the triplex: the first part is red copper pipe 4, the second part is silica gel elastomer 5, and the third part is heat absorbing aluminum fin 7.

The second part is arranged in the first part, and both ends of the inner part of the first part are provided with sealing plugs 6 for preventing the second part from falling out; the third part is welded on the surface of the first part through laser; the three parts are combined together through a welding process to form a heat absorbing body with a self-anti-freezing protection function;

the second part of the silicone elastomer 5 is made of silicone rubber according to a certain density (0.5-0.6 g/cm)³) The elastic body is formed by extrusion, has high and low temperature resistance and can rebound after contraction. The material of the silica gel elastomer 5 is important, the material is nontoxic and tasteless, has no side effect, has good water tolerance, long-term weather resistance, good high-temperature and low-temperature resistance and proper elasticity, and the silica gel elastomer 5 is food-grade silica gel, the density of the silica gel elastomer 5 must be ensured to bear certain pressure, and the silica gel elastomer is not deformed in the system operation.

The flexible hose that probably has other materials to utilize in the existing market reaches the mesh of preventing frostbite, and this kind of design has a lot of potential safety hazards unfavorable to the human body because the uncertainty of material exists to fill the air of taking pressure, under system's water pressure effect, the space of reserving in the hose is compressed and is reduced, also uses easily for a long time and leads to the air to spill over, can not reach the purpose of absorption water expansion volume, still causes very easily like this and freezes, these problems have been avoided to this application design fine.
