Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is done further in detailDescribe. Following instance is used for illustrating the present invention, but is not used for limiting the scope of the invention.
As shown in Figure 1, solar energy heat-storage generator unit of the present invention, comprises all-glass vacuum collectionHeat pipe 1, heat exchanger tube 2 and pedestal 8. All-glass vacuum thermal-collecting tube comprises inner glass tube 12 and outerGlass tube 11, inner glass tube 12 and outer glass pipe 11 are similar test tube shape, inner glass tube12 and outer glass pipe 11 between coaxially arrange, and form vacuum space between the two. At interior glassOn glass pipe 12, scribble heat-absorbing material. Pedestal 8 has a Plane Installation face, and heat exchanger tube 2 isHave the sealed tube of cavity, heat exchanger tube 2 connects or other fixed forms by welding, flange,The one end that is provided with water inlet 21 and delivery port 22 is arranged on the installed surface of pedestal 8. Heat exchangePipe 2 water inlet 21 and the delivery ports 22 that are provided with for being connected with external pipe, water inlet 21Pass pedestal with delivery port 22 by tube connector, be connected with external pipe. All-glass vacuum collectionHeat pipe 1 tips upside down on pedestal 8, and empty set is at the outside of heat exchanger tube 2, all-glass vacuum thermal-collecting tubeThe outer wall of 1 inwall and heat exchanger tube 2 has space 3, by an airtight full glass of sealing ring 9The aperture position of glass vacuum heat collection pipe 1, the inwall of all-glass vacuum thermal-collecting tube 1 and heat exchanger tube 2The space 3 that has of outer wall be enclosure space. In space 3, be provided with thermo-electric generation sheet 4; The temperature differenceThe cold junction of generating sheet 4 contacts with the outer wall of heat exchanger tube 2; The inwall of all-glass vacuum thermal-collecting tube 1Be connected with the hot junction heat conduction of thermo-electric generation sheet 4. Concrete, thermo-electric generation sheet 4 is true with full glassBetween the inwall of empty set heat pipe 1, be provided with conducting strip 5, the one side of conducting strip 5 and all-glass vacuumThe inwall contact of thermal-collecting tube 1, another side contacts with the hot junction of thermo-electric generation sheet 4. Thermo-electric generationSheet 4 is connected with outside battery 6 by wire 7. By conducting strip 5 by all-glass vacuum collectionThe heat energy that heat pipe 1 absorbs is transmitted to thermo-electric generation sheet 4 from the inwall of all-glass vacuum thermal-collecting tube 1,Between the hot junction of thermo-electric generation sheet 4 and cold junction, there is the larger temperature difference, a fraction of heat energy(greatly between 1%～5%) is changed into electric energy by thermo-electric generation sheet 4, and outwards output is electricCan, by outside battery 6, electric energy unification is stored, so that use; Large portion in additionDivide heat energy to be conducted to heat exchanger tube 2 by thermo-electric generation sheet 4, the inner chamber of heat exchanger tube 2 is by water inlet21 flow into water at low temperature, and after heat exchange, the temperature of water improves, and flow out and change from delivery port 22Heat pipe 2, thus ensure that the temperature of heat exchanger tube 2 is lower all the time, the hot junction of thermo-electric generation sheet 4 withThe temperature difference between cold junction is larger, stably exports electric energy.
Preferably, conducting strip 5 has elasticity, uses flexible conducting strip 5 can be stuck in full glassBetween the gap 3 of vacuum heat collection pipe 1 and heat pipe 2. Preferably, conducting strip 5 is led for ripple springBacking, is fastened on thermo-electric generation sheet 4 on heat exchanger tube 2 by ripple spring conducting strip, does not needAdditional fixed installation structure is installed thermo-electric generation sheet, makes simple in structure, easy for installation.
Preferably, heat exchanger tube 2 adopts stainless steel tube to make, and stainless steel tube has good heat conductionEffect, and low price, long service life.
Preferably, thermo-electric generation sheet 4 can have polylith, and polylith thermo-electric generation sheet 4 circumferential arrangement existThe outer wall of heat exchanger tube 2. In reality, all-glass vacuum thermal-collecting tube 1 only has part can be subject to tooThe direct irradiation of sunlight, high by the portion temperature of direct irradiation, other portion temperature are lower. CauseThis, both can only install thermo-electric generation sheet at all-glass vacuum thermal-collecting tube towards a side of sunshine4, also can thermo-electric generation sheet be all set in whole heat exchanger tube outer wall surrounding.
Preferably, between thermo-electric generation sheet 4 and heat exchanger tube 2, scribble conduction material, make heat energy energyEnough conduct to heat exchanger tube 2 from thermo-electric generation sheet 4 preferably.
It should be noted that, in the present embodiment, the opening portion of all-glass vacuum thermal-collecting tube 1 is logicalCross sealing ring 9 airtight with pedestal 8, prevent what all-glass vacuum thermal-collecting tube 1 inner glass tube 12 from absorbingHeat energy dissipation, the outer wall that heat energy also can be from the air transmitted in space 3 to heat exchanger tube 2. Full glassVacuum heat collection pipe 1 empty set is in the time of heat exchanger tube 2, and all-glass vacuum thermal-collecting tube 1 opening portion does not carry outSealing, and adopt open design also can use.
The present invention also provides a kind of solar water heater, this solar water heater comprise 2 above-mentionedDescribed solar energy heat-storage generator unit, series connection successively between 2 solar energy heat-storage generator units,As shown in Figure 2, the water inlet 21 and outside cold water pipe of first order solar energy heat-storage generator unitConnect, its delivery port 22 is connected with the water inlet 21 of second level solar energy heat-storage generator unit;The delivery port of second level solar energy heat-storage generator unit is connected with water tank 10. Through the two-stage sunWater after the heating of energy heat accumulation generator unit is stored by water tank, during in order to people's demand, uses. The sunCan also be formed by 3 above solar energy heat-storage generator unit series connection by water heater.
In solar water heater, the heat energy that absorbs and absorbed by water by all-glass vacuum thermal-collecting tube30% left and right that accounts for solar energy, the temperature difference between all-glass vacuum thermal-collecting tube and heat exchanger tubeGreatly, thermo-electric generation sheet is set between all-glass vacuum thermal-collecting tube and heat exchanger tube, heat energy is transmittingProcess in, part converts electric energy to. Certainly the ratio that the heat energy of the conversion of thermo-electric generation sheet occupiesExample is very little, large about 1～5% left and right of heat energy, therefore, and at the solar energy of solar water heaterThermo-electric generation sheet is installed in heat storage units, heat energy Partial Conversion is become to electric energy, can't be to the sunThe heat storage capacity of energy water heater produces large impact, has practicality. Use has of the present inventionSolar water heater, in the process of heat accumulation, obtains electric energy by the generating of thermo-electric generation sheet, carriesThe utilization rate of high solar, the electric energy storing can be in order to provide mobile phone charging or direct currentThe use of low power electric appliance.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention,Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc.,Within all should being included in protection scope of the present invention.
