Description

The taper solar water heater of no vacuum tube, no adiabator layer, no shelf

Technical field

The utility model relates to solar utilization technique, particularly a kind of taper solar water heater that does not have vacuum tube, no adiabator layer, no shelf.

Background technology

Existing vacuum tube collector formula solar water heater, basic structure are the heat conduction end connection attemperaters at vacuum tube collector arranged side by side, and this water heater is mainly because of its vacuum tube collector structure and complex process cost height; And vacuum tube collector often bursts accident and takes place, and fears that hail attacks, so the life-span is not long.Moreover the vacuum tube collector of this type solar water heater and attemperater be fixedly mounted on roof or balcony with shelf, and it is big to take up space, and it is serious to go for a drive.In a word, the taper solar water heater cost performance of the no vacuum tube of this type, no adiabator layer, no shelf is low.

Summary of the invention

A kind of taper solar water heater that does not have vacuum tube, no adiabator layer, no shelf of the utility model design overcomes the defective of prior solar water heater, and is simple in structure, compact, the life-span is long, cost is low, cost performance is high.

The utility model is realized through following technical proposals.

Show like Fig. 1.The end face of interior conical shell 5 is connected in the upper surface of plate 7; Plate 7 perhaps is that the mushroom cap shape (is the plane promptly for the circle tabular; Be the spherical calotte shape above); Interior conical shell 5 usefulness light transmissive materials or Heat Conduction Material are made; If when making with Heat Conduction Material, be coated with existing high solar absorptance has the selective coating material of low radiance again or paints dark color (blackish green, be coated with deeply, coating such as indigo plant) in the upper surface of its outer surface and plate 7; If interior conical shell 5 usefulness light transmissive materials are made, then the upper surface of surface and plate 7 is coated with the selective coating material or paints dark color within it; The end face of outer conical shell 3 is connected in the upper surface of base plate 1, and outer conical shell 3 usefulness light transmissive materials are made, and a groove of falling U is arranged below the base plate 1; Conical shell 5 one intervals in outer conical shell 3 leaves, base plate 1 leaves plate 7 one downwards at interval, and a cavity is formed at two intervals, perhaps said cavity is evacuated.

Air escape valve 4 is used the heat-insulation and heat-preservation material, the lower end of air escape valve 4 pass successively outer conical shell 3 top, interior conical shell 5 the top and with they sealed attachment, 4 of air escape valves let air run out of from bottom to top, do not allow air run from top to bottom into; If said cavity is not evacuated, then air escape valve 4 is on that section pipe between the heat collector cavity and beats some cross through hole, if heat collector cavity vacuumizes, does not then beat said through hole.

The vertical section of a pipe vertical section of 8, No. two pipes 10, the vertical section of liquid level sensor 2 all penetrate successively base plate 1, plate 7 and with they sealed attachment, the horizontal segment of a pipe 8, the horizontal segment of No. two pipes 10, the horizontal segment of liquid level sensor 2 are all drawn from the groove of falling U of base plate 1.

The electric heater 6 of band temperature control function is fixed on the upper surface of plate 7, and lead 9 is power transmission lines of electric heater 6, and lead 9 slave plates 7, base plate 1 pass, and draw from the groove of falling U of base plate 1.

The back of the body of conical shell 3 sun one side is provided with reflector 11 outside.Certainly, if receive under condition restriction or the inappropriate situation reflector 11 not to be set.

When using the taper solar water heater of said no vacuum tube, no adiabator layer, no shelf, cold water is injected interior conical shell 5 from a pipe 8.When water level reached the upper end (among the figure shown in the dotted line) of liquid level sensor 2, liquid level sensor 2 sent signal, disconnected immediately notes the, and when water level is lower than setting value, notes again.If interior conical shell 5 usefulness light transmissive materials are made, sunlight sees through outer conical shell 3, interior conical shell 5 successively, directly the interior water of conical shell 5 in the heating; If interior conical shell 5 usefulness Heat Conduction Materials are made, sunlight sees through conical shell 5 in the outer conical shell 3 back heating successively, and interior conical shell 5 adds hot water again.All the time according to date or on the date of severe cold, but opening electric heater 6, said taper solar water heater just uses as water heater, but also opening electric heater 6 can prevent that said taper solar water heater is by spalling.When using hot water, draw from No. two pipes 10.

Reflector 11 can arrive outer conical shell 3 with the sunlight reflected of the positive side of outer conical shell 3 back ofs the body, increases solar energy utilization ratio.

When water in the interior conical shell 5 is heated and when expanding, can the air of interior conical shell 5 inner tops be released air escape valve 4.If said heat collector cavity is not evacuated, then heat collector cavity is heated and the air that expands, will run out of many through air escape valve 4 (usefulness be in beaten on that section pipe between the heat collector cavity some cross through hole); If said heat collector cavity vacuumizes, air escape valve 4 usefulness are in does not get through the hole on that section pipe between the heat collector cavity.Certainly; Heat collector cavity vacuumizes; The taper solar water heater heat insulating ability of said no vacuum tube, no adiabator layer, no shelf is fine; Heat collector cavity does not vacuumize, and runs out of many air owing to be heated, and the taper solar water heater warmer of said no vacuum tube, no adiabator layer, no shelf also has heat insulating ability preferably.Take out and do not vacuumize, definite according to using geography, weather, environment and user to accept the wish of price.

The effect that the utility model is useful:

1, because the taper solar water heater structure compact of said no vacuum tube, no adiabator layer, no shelf, materials province, the vacuum tube collector that volume little (when not establishing reflector) need not costliness; Without insulation material, good manufacturability need not be installed shelf; Therefore cost is low, easy care.

2, because the taper solar water heater main body of said no vacuum tube, no adiabator layer, no shelf is a taper; Taper makes its opposing atmospheric pressure (when vacuumizing) that affluence far arranged; Make its wind resistance, rain, hail ability strong; Do not have vacuum tube collector and its its specific structure, do not have the problem of bursting, so the life-span is long.

3, the taper solar water heater main body of said no vacuum tube, no adiabator layer, no shelf is a taper; Can gather sunlight greater than 180 ° of scopes (as reflector time scope be 360 °); And the solar water heater lighting scope of existing non-tracks sunlight formula is about 160 °; Therefore the taper solar water heater of said no vacuum tube, no adiabator layer, no shelf is higher than the solar water heater utilization rate of existing non-tracks sunlight formula; Although collecting efficiency possibly be lower than vacuum tube collector under the situation not vacuumizing, the thermal-arrest benefit is not low.And the solar water heater of tracks sunlight formula, the daylighting scope is 360 °, but the cost increase is many, and power consumption, reliability reduces.So the taper solar water heater of said in a word no vacuum tube, no adiabator layer, no shelf has significantly high cost performance than prior solar water heater.

4, owing to above advantage, the taper solar water heater of said no vacuum tube, no adiabator layer, no shelf.Have a extensive future, be prone to promote.
