Utility model has clear advantage and beneficial effect compared with prior art.By above-mentioned technical proposal, this reality
At least there is following advantages and beneficial effect with new type solar energy regenerative apparatus：
First, heat-conducting medium is used as using solar energy heating, oil, heat-transfer effect is good.
2nd, using phase change heat storage material, the thermal efficiency is high, and quantity of heat storage is big, adverse weather can be overcome to influence.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand the skill of the utility model
Art means, and being practiced according to the content of specification, and in order to allow the above and other purpose, feature of the utility model
It can be become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate attached drawing, described in detail as follows.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is the structure diagram of the utility model.
Embodiment
This solar heat-storing device, referring to Fig. 1, including shell body 1, thermal insulation material 2, inner housing 3, heat storage 4, closing
Shell body 1 and inner housing 3 between fill thermal insulation material 2, prevent the thermal loss in inner housing 3；Installation stores among inner housing 3
Hot body；A piece high temperature endothermic pipe 5 is installed from present apparatus bottom, high temperature endothermic pipe 5 is worn from heat storage 4 to 3 top of inner housing, from
Present apparatus bottom is installed a low temperature endothermic tube 7 and is worn to 3 lower part of inner housing, is so conducive to 13 continuous circulation heat absorption of conduction oil；
For the ease of controlling conduction oil 13, the outside of high temperature endothermic pipe 5 installation high temperature endothermic pipe valve 6, the outside of low temperature endothermic tube 7 installation low temperature
Absorb heat pipe valve 8；A piece high temperature exothermic pipe 9 is installed from 3 upper outside of present apparatus inner housing, 3 lower outside of inner housing installs one
Exotherm pipe 11, is so conducive to conduction oil 13 and constantly circulates heat release；In order to heat the release of energy without using thermal energy time control,
High temperature exothermic pipe valve 10, the outside of Exotherm pipe 11 installation Exotherm pipe valve 12 are installed outside high temperature exothermic pipe 9；Inner housing
3 internal clearances are full of conduction oil 13.If heat accumulating sections 4 set dried layer heat storage units 14, every layer includes several phase-change heat accumulation units
14, heat storage units 14 are cellular, the phase-change heat-storage material 16 of 15 enclosed inside of heat vessel in each layer phase-change heat accumulation unit 14
Fusing point be gradually reduced from top to bottom.
In use, high temperature endothermic pipe 5 and low temperature endothermic tube 7 couple with solar collector, high temperature exothermic pipe 9 and low temperature are put
Heat pipe 11 couples with thermal energy release.Fine day at sunrise, opens high temperature endothermic pipe valve 6 and low temperature heat absorption pipe valve 8, low temperature conduction oil
Solar collector is sent to from 3 lower part of inner housing by low temperature endothermic tube 7, leading for heat is constantly absorbed from solar collector
Deep fat 13 is sent to the top of inner housing 3 from high temperature endothermic pipe 5, is stored in by heat exchange in heat storage 4.When needing thermal energy,
High temperature exothermic valve 10 and Exotherm pipe valve 12 are opened, the high temperature heat conductive oil of 3 internal upper part of inner housing is transmitted from high temperature exothermic pipe 9
To thermal energy releases such as pots, low temperature conduction oil returns to the lower part in inner housing 3 again from Exotherm pipe 11.Because of conduction oil and storage
The accumulation of heat thermal capacity of hot body is big, and temperature is up to 300-400 DEG C or so, can meet the temperature requirements heated up water, cook, prepared food.
Specifically, conduction oil 13 is in motion process from bottom to top, first by orlop heat storage units 14
Phase-change heat-storage material 16 inside heart position, with heat vessel 15 produces heat exchange, and heat is stored in the relatively low phase transformation storage of fusing point
In hot material 16；Conduction oil 13 continues upward through the second layer and (sees) that phase-change heat accumulation unit 14 carries out heat accumulation from bottom to top afterwards,
And so on, after the phase-change heat accumulation unit 14 of the superiors, conduction oil 13 is pooled to the top of inner housing 3.Since position is got over
Low, the fusing point of phase-change heat-storage material 16 is lower so that the heat that the phase-change heat-storage material 16 of lower floor absorbs is less, such conduction oil
13 heats carried are stored in the phase-change heat-storage material 16 on upper strata as much as possible, can at utmost store heat, and
It ensure that the upper temp highest of inner housing 3, can farthest meet to use needs.
Above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications
Limitation to the utility model.
