Abstract

The utility model discloses a flat-plate solar collector utilizing liquid to absorb heat. The flat-plate solar collector comprises a heat absorbing plate made of glass; the sunlight can pass through the glass for directly heating a dark liquid in a glass flow channel; the dark liquid transfers the heat to water for being used through the negative pressure circulation; carbon dioxide gas is sealed between the heat absorbing plate and a transparent cover plate; and the characteristics that the coefficient of thermal conductivity of the carbon dioxide gas is smaller than that of air and the thermal radiation is impossible at a normal temperature are utilized for enhancing the thermal insulation effect of the system. The flat-plate solar collector changes the heat absorbing manner of the traditional flat plate solar collector that utilizing the metal surface coating into the manner that utilizing the dark liquid in the glass flow channel to absorb the heat, thereby dispensing with the metal structure and the coating which are expensive, and achieving the purposes of simplifying the manufacturing process and reducing the cost.

Description

A kind of liquid heat absorption type flat-plate solar collector
Technical field
The utility model relates to a kind of solar energy heat utilization device, is specifically related to a kind of flat-plate solar collector.
Background technology
At present, solar thermal collector mainly contains vacuum tube solar heating element and flat-plate solar collector, wherein flat-plate solar collector more attractive in appearance and can better with architecture-integral.But shortcoming is that its metal absorber plate manufacture difficulty is bigger, and cost is higher! So it is universal like that in China at present not as vacuum tube solar heating element.
Summary of the invention
The purpose of this utility model is the problems referred to above at flat-plate solar collector, a kind of liquid heat absorption type flat-plate solar collector is provided, use glass to replace metal to make absorber plate, the interior adopting dark liquid of plate directly absorbs the sunshine heat and utilizes, so not only utilize glass to replace expensive metal material, and save heat absorbing coating, reach simplified manufacturing technique, the purpose that reduces cost.
For achieving the above object, the technical solution of the utility model is as follows: a kind of liquid heat absorption type flat-plate solar collector comprises absorber plate, transparent cover plate, heat-insulation layer, water circulating pump, incubator and heat exchanger.The absorber plate runner exit links to each other with attemperater with water circulating pump by heat exchanger, the runner import directly links to each other with incubator, absorber plate is made of two glass plates that fit together up and down, wherein having at least the cross section is arranged on the glass sheets is the striped of dentation, and striped formed the runner that can pass through for liquid after two glass sheets were fitted.In the absorber plate runner adopting dark liquid is arranged, between absorber plate and transparent cover plate, be closed with carbon dioxide in addition, utilize carbon dioxide thermal conductivity ratio air little and can not see through the thermal-radiating characteristics of normal temperature, strengthen the heat insulation effect of system.During operation water circulating pump with the adopting dark liquid in the absorber plate runner (as ink, painted antifreezing agent etc.) pump in incubator, make and form negative pressure in the absorber plate runner and in incubator, absorb water by pipeline, so just formed the negative pressure circulation, this negative pressure circulation can be avoided up and down, and two glass plates are strutted by the liquid normal pressure, for guaranteeing the negative pressure in the absorber plate runner, the installation site of incubator can not be higher than absorber plate, and have steam vent on the incubator, to guarantee that incubator can not form high pressure the absorber plate runner is produced normal pressure.The another kind structure of absorber plate is integrally formed with glass, and absorber plate is made of the monolithic glass plate, offers the above flow channel for liquids of two rows in the glass plate, and the two rows runner staggers mutually.The sunshine of gross area can be guaranteed to use like this, the intensity of glass absorber plate can be guaranteed again, but bearing operation also.
The beneficial effects of the utility model are, the adopting dark liquid that utilizes the coating for metal surfaces heat absorption to change in the glass channel traditional flat-plate solar collector absorbs heat, saved expensive metal structure and coating like this, reached simplified manufacturing technique, the purpose that reduces cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of utility model.
Fig. 2 is the integrally formed cross section of fluid channel schematic diagram of glass.
1. transparent cover plates among the figure, 2. upper glass plates, 3. runner, 4. lower glass plate, 5. heat-insulation layer, 6. heat exchanger, 7. incubator, 8. water circulating pump, 9. steam vent, 10. one-body molded glass absorber plate, 11. one-body molded runners.
The specific embodiment
In Fig. 1, between transparent cover plate (1) and the heat-insulation layer (5) is absorber plate, absorber plate is by upper glass plates (2) and lower glass plate (4) formation that fits together, it is the striped of dentation that the cross section is arranged on the lower glass plate (4), after fitting, upper glass plates (2) and lower glass plate (4) just formed flow channel for liquids (3) like this, runner is full of adopting dark liquid such as black ink in (3), runner (3) outlet links to each other with incubator (7) with water circulating pump (8) by heat exchanger (6), runner (3) import directly links to each other with incubator (7), have steam vent (9) on the incubator (7), charge into carbon dioxide between transparent cover plate (1) and the absorber plate.
When sunlight is arranged, sunlight directly sees through transparent cover plate (1) and upper glass plates (2) and is absorbed by the black ink in the runner (3), start water circulating pump (8) simultaneously, absorb water from runner (3), toward incubator (7) internal pump water, make the runner (3) in the absorber plate form negative pressure, absorb water in incubator (7) by runner (3) import, thereby form the adopting dark liquid circulation of negative pressure, the adopting dark liquid of circulation heats water for utilization when the heat exchanger of flowing through (6).The adopting dark liquid circulation of this negative pressure can not make it distending to upper glass plates (2) and lower glass plate (4) the formation normal pressure that constitutes absorber plate, if owing to other reason, raise gradually such as operation back incubator (7) temperature and to make air expanded by heating in the case, when pressure raises, steam vent (9) exhaust guarantees to make absorber plate can not arrive malleation and destroys.
Fig. 2 is another structure of absorber plate, promptly be with the integrally formed cross section of fluid channel schematic diagram of glass, in Fig. 2, have one-body molded runner (11) in the one-body molded glass absorber plate (10), the two rows runner staggers mutually, the sunshine of gross area can be guaranteed to use like this, the intensity of glass absorber plate can be guaranteed again, but bearing operation also.
