Technical field
The utility model relates to a kind of heat collector, relates to a kind of novel solar water heater heat collector specifically.
Background technology
Solar energy is a kind of cleaning, economy, the stable energy, and solar energy is compared with fossil fuel such as coal, oil, natural gas, nuclear energy as a kind of energy; Have the following advantages: (1) is general: the solar light cultivated illumination the earth; No matter land or ocean, no matter high mountain or island all have everywhere; Directly development and utilization, and must not exploit and transport; (2) harmless: development and use solar energy does not pollute the environment, and it is one of energy that cleans most, and in environmental pollution more and more serious today, this point is extremely valuable; (3) huge: the annual lip-deep solar radiant energy of the earth that arrives is equivalent to 130,000,000,000,000 tons of standard coals approximately, and its total amount belongs to the maximum energy that can develop in the world now; (4) permanent: according to the nuclear energy rate estimation that the present sun produces, the reserves of hydrogen are enough kept over ten billion year, and the life-span of the earth also is about tens years, and in this sense, energy that we can say the sun is nexhaustible.
Solar water heater is to be converted into heat energy to solar energy, and water is heated to high-temperature from low temperature, uses to satisfy the hot water of people in life, production.The solar water heater industry has formed industrialization production through fast development in a few years, and technology is constantly brought forth new ideas, and properties of product are are constantly improved and optimizated, and is used widely at present.Solar water heater is made up of heat collector, storage tank and related accessories, converts solar energy to heat energy and mainly relies on heat collector, and present employed solar water heater heat-collecting device manufacturing cost is high, and the thermal absorptivity and the thermal efficiency are lower.
The utility model content
The problem that the utility model will solve is to above problem, and the novel solar water heater that a kind of cost is low, the thermal efficiency is high heat collector is provided.
For addressing the above problem; The technical scheme that the utility model adopted is: a kind of novel solar water heater heat collector; Said heat collector comprises flat-plate heat pipe; Said flat-plate heat pipe top scribbles blackboard paint, and the arranged outside of said flat-plate heat pipe has ultrawhite safety glass, and the bottom of said flat-plate heat pipe is provided with the topping up pipe.
A kind of concrete prioritization scheme, said flat-plate heat pipe is provided with heat-insulation layer.
A kind of concrete prioritization scheme, said flat-plate heat pipe is connected with heat collection water tank through collector pipe.
A kind of concrete prioritization scheme, said heat collection water tank is provided with water inlet and delivery port.
The utility model is taked above technical scheme, has the following advantages: heat collector comprises flat-plate heat pipe, and flat-plate heat pipe top scribbles blackboard paint; The arranged outside of flat-plate heat pipe has ultrawhite safety glass, and the bottom of flat-plate heat pipe is provided with the topping up pipe, and solar radiation sees through ultrawhite safety glass; Flat-plate heat pipe absorb to see through the working medium in the luminous energy heated plate heat pipe of ultrawhite safety glass then, then the working medium of heat absorption upwards carry with collector pipe in the lower water of temperature carry out heat exchange, working medium heat release condensation comes back to the bottom along tube wall; So circulation, the final purpose that realizes the cold water in the collector pipe is heated to utilizable hot water, the working medium of absorbing heat in the flat-plate heat pipe; Cooling through collector pipe; With the working medium after the cooling, continue to absorb heat, this heat collector low cost of manufacture, thermal efficiency height from solar radiation.
Employing flat-plate heat pipe technology; Can effectively solve heat radiation and reduce thermograde; The capillary flat-plate heat pipe reaches high heat conductance through reducing thermal resistance; Guarantee that heat in time transmits fast, replace metal substrate can strengthen the thermal diffusion of substrate greatly with the heat pipe substrate, the isothermal of hot plate also is of value to the reduction thermal resistance.The flat-plate heat pipe heat collector has the structure of gross area absorption and thermotransport, the non-finned effect, and the gross area samming, the convection current heat waste is little, thereby has the high thermal efficiency.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of novel solar water heater heat collector among the utility model embodiment;
Accompanying drawing 2 is the upward view of accompanying drawing 1.
Among the figure:
The 1-deck; The 2-flat-plate heat pipe; 3-ultrawhite safety glass; The 4-collector pipe; The 5-heat collection water tank; The 6-delivery port; The 7-water inlet; The 8-heat-insulation layer; The 9-blackboard paint; 10-topping up pipe.
The specific embodiment
Embodiment: shown in accompanying drawing 1 and accompanying drawing 2; A kind of novel solar water heater heat collector; Comprise flat-plate heat pipe 2, flat-plate heat pipe 2 tops scribble blackboard paint 9, and the arranged outside of flat-plate heat pipe 2 has ultrawhite safety glass 3; The bottom of said flat-plate heat pipe 2 is provided with topping up pipe 10, through topping up pipe 10 required working medium is transported in the cavity of flat-plate heat pipe 2.
