Description

Interior condensation metal inner tube type solar energy heat collector
Technical field
The present invention relates to a kind of interior condensation metal inner tube type solar energy heat collector, belong to solar energy heat utilization field.
Background technology
Solar water heater is current universal the widest, benefits the solar thermal utilization form that the masses are maximum.Existing solar water heater generally adopts full-glass solar energy vacuum tube as heat-collecting part, this class technology in vacuum tube is ripe, stable, with low cost, but its maximum defect is can not pressure-bearing, can not optically focused, cannot produce above boiling water or the steam of 100 degree, majority only can, for bathing, can not be used widely by the other field outside bathing.Around the problems referred to above, existing many people have proposed multiple solution, in numerous schemes, there are two kinds of schemes and the present invention more approaching, the one, application number is the interior light focusing type all-glass vacuum thermal-arrest > > of the < < of 200720000692.5 propositions, this scheme has solved the problem that just can obtain the 100 above boiling water of degree or steam without following the tracks of, but because it is still, adopt full glass material to fail to solve pressure-bearing problem, it is restricted aspect popularizing, the 2nd, application number is the < < metal absorption tube straight through type vacuum solar energy thermal-collecting tube > > of 200620135895.0 propositions, this scheme has solved pressure-bearing problem preferably, when itself and solar tracking coordinative composition of equipments are used, can obtain good Heat-collecting effect, but in non-solar tracking occasion, because it has installed glass stria tube cover additional for solving the problem of expanding with heat and contract with cold between metal and glass at two ends, cause the effective daylighting area of its inner tube to be far smaller than the shared area of outer tube, daylighting effect is poor, under the general non-solar tracking condition of illumination, more difficult above steam or the boiling water of 100 degree that make of such vacuum tube, add such vacuum tube cost high, body weight, cause it to be difficult to popularize in non-solar tracking occasion.The problem to be solved in the present invention is: a kind of interior condensation metal inner tube type solar energy heat collector is provided, can solve optically focused and pressure-bearing problem simultaneously, make it that steam or boiling water more than 100 degree can be provided safely under the condition of not following the tracks of the sun, solar thermal utilization effect is widely applied to other aspects outside bathing.
Summary of the invention
Technical scheme of the present invention: a kind of interior condensation metal inner tube type solar energy heat collector, comprise glass outer tube (1), in glass outer tube (1), be fitted with metal absorption tube (3) and the metal adjustable pipe (4) of both ends open, between glass outer tube (1) and metal absorption tube (3), be fitted with involute-type reflecting surface (2) and fill fixture (18), the two ends of metal absorption tube (3) outer wall are inwardly set with straight choma (7) successively from opening part, glass line ring (6), alloy hoop (5), the straight straight notch portion inwall of choma (7) and the welding of the outer wall of metal absorption tube (3) port position, (7) one end welding of the other end and glass line ring (6), (6) one end welding of the other end and alloy hoop (5), the other end of two alloy hoops in two ends (5) respectively with the two ends burn-back of glass outer tube (1), metal absorption tube (3) outer wall all scribbles solar absorbing layer except needing weld, the two-port of metal absorption tube (3) and metal adjustable pipe (4) is respectively by upper and lower end cap (10) (8) welded seal, bottom end cover (8) is welded with water inlet pipe and water outlet pipe (9), upper end cover (10) is welded with gland steam exhauster (11), with the air between exhaust equipment emptying glass outer tube (1) and metal absorption tube (3), form vacuum interlayer encapsulation.
Described metal adjustable pipe (4) is to be inserted in metal absorption tube (3) with metal absorption tube (3) with long concentric and the little straight pipe of diameter, in metal adjustable pipe (4), be fitted with piston (14) and the screw rod (13) being connected mutually with piston, screw rod (13) is connected with motor (12) through the preformed hole in the middle of upper end cover (10), motor (12) is fixed on upper end cover (10) outside, motor (12) also can replace with hand-cranking riser, on the body that metal adjustable pipe (4) is located bottom, leave hole (15), water can be entered in metal adjustable pipe (4).
Described involute-type reflecting surface (2) is that by two, to take metal absorption tube (3) outer wall circle be the silver-plated or aluminium-plated reflecting surface of making in involute (16) (17) the involute surface top layer that translation was formed of basic circle, its material is duroplasts or other materials, two involutes (16) (17) symmetry and starting point are connected, the connected point of starting point is the outer wall that basic point is close to metal absorption tube (3), the length of involute-type reflecting surface (2) equates with glass outer tube (1) or is slightly long, space between involute-type reflecting surface (2) bottom and glass outer tube (1) is filled fixing with heatpiston's foam (18).Advantage of the present invention: 1, the present invention can solve optically focused and pressure-bearing problem simultaneously.The A/F of involute-type reflecting surface is approximately three times of left and right of metal absorption tube external diameter, involute-type reflecting surface can be by the sunlight being irradiated on it, comprise that direct light and scattered light all reflex to metal absorption tube outer surface and absorb for metal absorption tube, the sunlight that metal absorption tube absorbs is sun direct irradiation three times of left and right thereon, therefore, the present invention does not need to follow the tracks of the sun, under better illumination condition, and can be by more than hundred degree of the cool water heating in pipe; Meanwhile, metal absorption tube can bear the pressure that water vapor produces, admittedly steam or boiling water can be provided more safely, breaks the limitation of existing water heater function.
2, existing water heater is assembled on attemperater and is formed by some vacuum tubes, and its daylight width of water heater of 16 vacuum tubes is 1.5 meters of left and right, and sunlight and the sunlight on water tank between vacuum tube all can not be absorbed by vacuum tube, in the present invention, the every increase of the external diameter Yi Ge unit of metal absorption tube, the A/F of involute-type reflecting surface just increases San Ge unit left and right, when the external diameter of metal absorption tube is increased to 0.5 meter, the A/F of involute-type reflecting surface is just increased to 1.5 left and right, (seeing Fig. 4), the common water heater daylight width of its daylight width and existing 16 dresses is suitable, therefore, the present invention can make single tube water heater, the i.e. water heater of a metal absorption tube, this water heater need not separately be joined attemperater, structure is simpler, and can not be by the absorption of metal absorption tube except the sunlight of two ends metal part, the solar ray energy of remainder is all absorbed and used, efficiency of utilization is higher.
3, because the piston in metal adjustable pipe can pass through motor or hand-cranking riser up-down adjustment, piston is heightened, and moisture storage capacity increases, otherwise, reduce.Therefore the present invention can be according to the moisture storage capacity in seasonal variations, illumination power or actual needs free adjustment water heater, in the hope of obtaining the hot water of optimum temperature, overcome water heater moisture storage capacity that application number 200720000692.5 schemes make freely regulated defect as required.
4, involute-type reflecting surface is encapsulated in glass outer tube, is not subject to contamination by dust, and reflecting effect is good; Reflecting layer does not contact with air, longer service life.
5, by removals such as two ends of the present invention end cap, metal adjustable pipe, piston, motors, allow metal absorption tube two ends connect, in optically focused metal straight-through vacuum tube.
6, novel structure of the present invention, simple installation, practical, reliability is high.
