Technical field
The present invention relates to a kind of heat collector that effectively utilizes solar energy to produce and store, transport heat; Be particularly related to a kind of novel infiltration type absorber plate that contains; The solar energy air heat collector of trapezium structure; This invention is for being heat catalysis with the air, and collects passive solar energy and give birth to the solar energy air heat collector that heat and autonomous electrical heating are integrated in one.
Background technology
In non-renewable resources day by day exhausted today; The excavation of energy field and application are just as the battlefield; How making good use of the non-renewable resources of having developed is topics that we relatively are concerned about; But some are walked the older generations that reclaim the forward position in energy development and begin for a long time to turn to new exploitation of energy resources and application to sight, and characteristics gain great popularity and that solar energy relies on is cheap, be widely used, reserves are abundant etc.Solar energy is that the overwhelming majority from the energy of outside of the earth celestial body (mainly being solar energy) necessary for human energy is all directly or indirectly from the sun.Each kind of plant is transformed into solar energy under chemical energy stores through photosynthesis in plant just.Fossil fuels such as coal, oil, natural gas also are by being embedded in underground animals and plants ancient times through forming very long geological epoch.They come down to the solar energy that is fixed up by ancient biological.In addition, water ability, wind energy, wave energy, energy by ocean current etc. are also all come by the solar energy conversion.At present, except solar electrical energy generation, solar energy is used the most general in building heating; Technology and product mainly contain passive solar house technology and solar water heater or the like; Passive solar house simple structure, cheap, but the back of building can't be realized heating, especially particularly like this like classroom, office building, meeting room and market for big depth building; The method that solves this difficult problem adopts the solar energy central heating system mostly; Characteristics such as heat collector is that vacuum tube, heat pipe type vacuum pipe and the flat plate collector of working medium is main with water, and poor, anti-incrustation scale of ubiquity anti-freezing property and pipeline anti-corrosion difficulty are big, and in a single day vacuum tube breaks causing a large amount of hot water losses; Systems operational requirement is high, maintenance difficulties is big, and reliability is low.And flat-plate collector is general and sun contact area is big inadequately, causes thermal-arrest insufficient, and effect is bad, and heat waste is excessive simultaneously.Which kind of version no matter, the shortcoming of three aspects below all existing: the first, the heat collector area of dissipation is big, the intensification path is short, causes the heat collector outlet temperature on the low side; The second, the hot-air in the heat collector is that nature flows, and circulation rate is slower, does not possess the outlet temperature regulatory function; The 3rd, heat collector does not possess the heat accumulation function yet, can not under night or adverse weather condition, work.
The problems referred to above have excited efforts at environmental protection person's continuous exploration, seek new application process, and the development novel heat collector is maximized favourable factors and minimized unfavourable ones, and under conditions permit, make the product function maximization as far as possible, and cost is minimum simultaneously, to reach maximum science, economic benefit.

xThe trapezoidal absorber plate 5 of infiltration type is fixing with absorber plate support 8 through stainless steel screw 7, and with the heat-insulation layer sealing, stainless steel stent 8 is fixing with heat-insulation layer 9 around the absorber plate 5.
Place one deck electric blanket 10 in the middle of the aluminium foil plate of heat-insulation layer 9 and the asbestos gauge, electric wire etc. pass from through wires hole 14.
Being benchmark by trapezoidal absorber plate 5 with recessed surface is divided into 2 parts of 2:1 with the inner core cavity, and 3 air inlets 3 are evenly distributed on the right side of the latter half heat-insulation layer 9, and 1 air outlet 4 is distributed in the left side of the first half heat-insulation layer 9 between two parties.
4 places are placed with blower fan 12 at air outlet, and its power supply is provided by solar panel.Be mainly used in and quicken flowing of the interior hot-air of heat collector, regulate outlet air temperature, and hot-air is transported to required place.
Air running in the present invention is following: cold air gets into second cavitys by air inlet 3, and the original temperature through second cavity is air preheat, the air after being heated; Upwards concentrate with trapezoidal absorber plate 5 and carry out the heating first time; Directly accept simultaneously the sunlight heating, air can get into first cavitys heating by the blinds hole on the trapezoidal absorber plate 5 or endothermic tube 6 these two approach respectively in this process, owing to cold and heat succeed each other and the special construction of trapezoidal absorber plate 5; Air will walk to form air-flow along the step surface upstream and downstream; So back and forth, the air after the heating gets into air outlet 4 at last, is delivered to the place that needs hot-air after being sucked by blower fan 12.If what heats received that weather condition influences in this process can open electric blanket 10 assistant heating.
The present invention can also can regulate the temperature in exit according to actual needs according to actual conditions open and close electrical heating, and the solar heating, solar energy drying and other that go for different situations need be used the place of solar heat air.
