Detailed description of the invention
In order to make those skilled in the art be more fully understood that, technical scheme can be practiced, below in conjunction with specifically
The invention will be further described for embodiment, but illustrated embodiment is not as a limitation of the invention.
A kind of heat storing and heat preserving water tumbler, concrete as it is shown in figure 1, include cup, and the bowl cover covered that is spirally connected with cup, cup
Including inwall 101 and outer wall 102, there is between inwall 101 and outer wall 102 mezzanine space;Inwall 101 is stainless steel,
Outer wall 102 is less than the lucite of 0.2W/ (m.K) for heat conductivity;Phase change heat storage material 103 it is provided with in described mezzanine space,
Inwall 101 and outer wall 102 carry out jacket layer sealing, sealing engagement at top lucite.
Preferably, the main component of above-mentioned phase change heat storage material 103 is Na2S2O3.5H2O crystal, specifically by
Na2S2O3.5H2O crystal, nucleator and thickening agent composition, wherein the addition of nucleator is Na2S2O3.5H2O crystal mass
0.5-2%, the addition of thickening agent is Na2S2O3.5H2The 4-5% of O crystal mass.
Preferably, above-mentioned nucleator is MgCl2.6H2O crystal, thickening agent is carboxymethyl cellulose.
Above-mentioned heat storing and heat preserving water tumbler uses the jacket structure of rustless steel inwall 101 and lucite outer wall 102, and its interlayer is empty
The above-mentioned phase change heat storage material 103 of interior placement.Wherein Na2S2O3.5H2O crystal is the main of inorganic hydrous salt phase transition heat-storing material
Composition, inorganic hydrous salt phase transition material has bigger heat of fusion and fixing fusing point (really inorganic hydrated salt abjection knot
The temperature of brilliant water), the water of crystallization of abjection makes salt melt and absorb heat, and inverse process occurs during cooling, absorb aqueous water and heat release again
Generate inorganic hydrated salt structure.Wherein Na2S2O3.5H2The melting temperature of O crystal is 48 DEG C, when the temperature of water water in the cup is more than 48
DEG C time, too high water temperature can be by Na2S2O3.5H2O absorption of crystal, abjection water of crystallization is melted for Na by this crystal2S2O3And aqueous water
And then the heat of storage 201kJ/kg, now water of crystallization becomes aqueous water and forms colloid with carboxymethyl cellulose;When water temperature is low
In 48 DEG C time, the aqueous water being stored in colloid and Na2S2O3Contact, regenerates Na2S2O3.5H2O crystal.Now, phase transformation
Heat-storing material 103 will release substantial amounts of heat, it is achieved the heating to water, but liberated heat will not make water temperature more than 48 DEG C, because of
For Na2S2O3.5H2The fusing point of O is 48 DEG C, and more than 48 DEG C, it will no longer undergo phase transition, also will not neither endothermic nor exothermic, final long time
Between by water temperature protect at 48 DEG C.It addition, Na2S2O3.5H2In O crystal, the effect of the carboxymethyl cellulose of mixing 4-5% acts as
Anti-phase separation agent, in order to will not be at Na2S2O3.5H2O occurs to generate other hydrates when melting or synthesize, and causes
Na2S2O3.5H2O crystal can not recycle, and makes the consequence that the heat storage performance of this hydrate declines;Mixing 0.5-2%'s
MgCl2.6H2O, as nucleator, prevents to occur to melt or solidification theoretical temperatures 48 DEG C during variations in temperature, occurs supercool existing
As, and then cause heat storage performance to decline.
Concrete, for Na in phase change heat storage material2S2O3.5H2The consumption of O quartz crystal, and inwall 101 and outer wall
The thickness of the mezzanine space between 102, is specifically calculated as follows:
(1) if this insulating cup is used for lower the temperature (being down to 55 DEG C from 90 DEG C), it is calculated as follows:
Q=cm △ t, wherein Q is up or reduces water temperature institute calorific requirement;C is that specific heat of water holds, about 4.2kJ/
(kg.K);M is quality;△ t is temperature variation.
M=ρ V, wherein m is quality;ρ is the density of water, about 1kg/L;V1It it is the volume of water;
Assume that this water tumbler capacity is V1=500mL, the water temperature poured into is 90 DEG C, calculates through above formula:
The quality of 500mL water is m1=0.5L × 1kg/L=0.5kg
Q=4.2kJ/ (kg.K) × 0.5kg × (90-55)=73.5kJ
And Na2S2O3.5H2The melting energy of O crystal is 201kJ/kg
Then it is reduced to suitable water temperature from water temperature and needs m2=73.5kJ/201kJ/kg=0.366kg's
Na2S2O3.5H2O crystal.
Due to known Na2S2O3.5H2The density of O crystal is 1.667g/cm3, the therefore volume V of this crystal required2=
366g/1.667g/cm3=220cm3。
Assume cup inside radius r1For 3cm, by π r2H=V1Can calculate h=17.68cm, therefore bottle further processing is
18cm is suitable.
By π r2 2h-πr1 2H=V2Can be calculated r2=3.6cm, therefore mezzanine space thickness is processed as 0.6cm.
If this insulating cup is used for heat up (rising to 45 DEG C from 15 DEG C), it is calculated as follows:
Q=4.2kJ/ (kg.K) × 0.5kg × (45-15)=63kJ
Owing to other condition is constant, the energy that the energy needed for simulation intensification calculating is compared needed for simulation cooling calculates is little,
Therefore this insulating cup is designed by the crystalline content in above-mentioned (1) and recuperation layer thickness.
To sum up, the Na in mezzanine space2S2O3.5H2O crystalline content is 0.366kg, and inwall 101 (stainless steel layer) with
Mezzanine space thickness between outer wall 102 (lucite) is at least 6mm.In order to avoid phase change heat storage material 103 occurs flatulence of heat type

Lucite insulation material can effectively hinder the conduction of heat and then effectively be incubated water, other two kinds of heat transfer sides
Formula solves the most using the following method: convection current only can be present in the situation that Drinking cup lid is opened, and therefore when water tumbler is opened, heat scatters and disappears
It is the fastest, in order to suitable water temperature being preserved the longer time, after having drunk water, bowl cover is covered and i.e. can effectively protect
Temperature.Secondly, the hot water in cup outwards can scatter and disappear energy with thermal-radiating form, and the outer wall side at mezzanine space posts one layer of aluminium foil
104, with reflective thermal radiation, the third lost form of heat can be hindered for silver color inside aluminium foil 104, this water tumbler is comprehensive
Three kinds of thermaltransmission modes prevent scattering and disappearing and then being incubated water for a long time of hot all approach as far as possible;Outside aluminium foil 104
Side is painted with black, can effectively utilize sunlight to heat the water in this insulating cup.Black aluminium foil 104 absorbs sunlight
After heat radiation, transmit heat to mezzanine space both sides, owing to the heat conductivity of lucite is 0.18W/ (m.K), stainless
Heat conductivity is 10-30W/ (m.K) scope, heat the having outside water tumbler of the heat radiation about 1.8% that aluminium foil 104 is absorbed
Machine glass material slowly runs off, and the heat of remaining 98.2% makes phase change heat storage material 103 undergo phase transition storage heat, for water
Water in Bei heating and thermal insulation at any time.When the coolant-temperature gage in water tumbler is higher than 48 DEG C, Na2S2O3.5H2O crystal melts completely, no longer
Store heat because of illumination, be the most no longer the water heating in water tumbler, make the water temperature long-time stable in water tumbler at 45-55 DEG C.
This structure can effectively prevent cool too fast of thermos cup water in winter.
Cup inwall 101 uses the stainless steel that heat conductivity is higher, and rustless steel contacts with water, and its heat conductivity exists
10-30W/ (m.K) scope, belongs to Heat Conduction Material, can make to carry out between phase change heat storage material 103 and water good heat exchange,
During hot water or less to the heat of heat conduction loss during water for cooling, and then realize the storage of efficient heat and release, the most right
Water carries out heating or lowering the temperature.Drink safer during additionally water is put in rustless steel, do not worry that plastics make Organic substance molten after being heated
In Xie Yushui, cause health safety issues.
This kind of water cup storage hot mode is simple, before using, only solarization meeting or fill with boiled water can need to have in cup under the sun
Imitate makes Na2S2O3.5H2Water of crystallization in O material becomes aqueous water, and then aqueous water forms jelly with carboxymethyl cellulose
Store energy.Storing heat is also constantly slowly heated water tumbler water temperature, so makes temperature retention time longer and water temperature typically will not surpass
Cross the crystallization temperature of this material, i.e. about 45-55 DEG C, allow people can be the most thirsty just drink warm water.When in water tumbler
When water cools off, phase change heat storage material layer can re-form Na2S2O3.5H2O crystal releases heat, heats water.Heat accumulation side
