Insulation is faced out under the demand of temperature, it is relative without the face of insulation, and fixed with mutual snap close mode, energy need not discharged
When amount, by the way that the uninsulated face of two panels energy collecting plate is staggered relatively, the insulation of two pieces of energy collecting plates faces out so that can measure
With preserve without scatter and disappear, need directly by energy collecting plate radiate occupation mode when reversing of position, make without insulation towards
Outside, so as to indoor formation exchange heat, using this scheme have can implementation result it is good, strong adaptability, workable is favourable
Part.Also, this mode is a kind of explanation of preferred embodiments, but is not limited thereto.When implementing of the invention, Ke Yigen
Appropriate substitutions and modifications are carried out according to user's demand.
In another example, described to be set to hot and cold cistern 2,3 outside, the hot and cold cistern is respectively by being engaged
Water circulation mechanism be connected with solar thermal collection system 4.Realized using this scheme by hot and cold pond and pass through water circulation mechanism
To temperature difference between dual temperature phase-change material, phase transformation is realized, while it is connected with solar thermal collection system, is advantageous to the synthesis of system
Utilize, there is the benefit of more preferable adaptability and practicality.Also, this mode is a kind of explanation of preferred embodiments,
But it is not limited thereto.When implementing of the invention, appropriate substitutions and modifications can be carried out according to user's demand.
The operation principle of accumulation of energy and exoergic mainly includes as follows in the present invention：
First, accumulation of energy, outside low-grade cold and hot amount is mainly imported energy storage equipment by it, and it mainly includes two kinds of work sides
Formula, first, the microchannel water circulation loop being made up of high molecule plastic branch pipe, its mean temperature to be supplied water in water circulation with
Induced phase transition when the phase-change material temperature difference is sufficiently large, so that energy storage is in phase-change material；Second, energy collecting plate is directly put
Put in the environment that the temperature difference between energy-accumulation material be present, such as the outdoor at night, or in hot water after bathing, environment temperature directly lures
Phase transformation is sent out so that energy storage is in phase-change material；
2nd, exoergic, energy in energy storage equipment is mainly discharged into interior by it, and it mainly includes two kinds of working methods, and one
It is the microchannel water circulation loop being made up of high molecule plastic branch pipe, supply water flat equal temperature and phase-change material in water circulation
The induced phase transition when temperature difference is sufficiently large so that stored energy is discharged into recirculated water, and then is taken corresponding indoor heat exchange to and set
In standby；Second, energy collecting plate will be directly placed at into interior, by the exposure of uninsulated one side indoors, by the air in bathroom and
Heat convection occurs and radiation heat transfer occurs with indoor other objects and discharges stored energy.
Embodiment：
First, material prepares
So that production unit specification is 1000*2000mm energy collecting plate as an example, selection external diameter is 6mm, and wall thickness is 1.2mm high scores
Raw material of the sub- plastic tube as branch pipe, such as PE-RT；Selection external diameter is 25mm, and wall thickness, which is 2.5mm polymer plastics expects pipe, is used as the
The raw material of one main, the second main；Selection thickness is 18mm, and with three layers of honeycomb channels, and each channel cross-section can hold
Raw material of the cored slab that 6mm plastic tubes of receiving penetrate as energy collecting plate, such as there is the PC carbonic acid polyesters of transparent configuration.
2nd, energy storage equipment is made
One end of plastic branch is welding on the first main and/or the second main with spacing 20mm respectively, forms accumulation of energy
And/or exoergic unit；The accumulation of energy or exoergic unit are passed through to the intermediate layer passage of cored slab, led to taking one every 20mm
Road；Intermediate layer is had in and uses Heat Conduction Material filling (such as graphite) in each passage of plastic branch, to improve heat conductivility；
The other end of plastic branch is welding on the first main and/or the second main, forms accumulation of energy and/or exoergic loop；Hollow
The side adhesive insulating layer of plate；Snap joint is installed at the both ends of first main, the second main, entered available for its energy storage equipment
Row is connected to form energy-storage system.
Idle channel or levels passage by remaining around intermediate layer passage, divided in a manner of interlocking and/or be relative
Not filling high temperature (35 DEG C) phase-change material, low temperature (18 DEG C) phase-change material；The end of whole hollow plate is sealed using silica gel
Dress, to avoid phase-change material and Heat Conduction Material from flowing out, and to cored slab with point/both ends of collector pipe add end cap to be formed to encapsulate
Overall structure, set and latch in edges of boards edge, for the later stage according to using needing two boards being relatively fixed, to be incubated direction finding
Outside.
To sum up, although the present invention can not be applied to domestic hot-water's such as bathing, wash with relatively low water temperature (35 --- 50 DEG C)
Occasion (>=60 DEG C) is washed, and manufacturing process is as heated, sterilization occasion, but by contrast, but relatively low water temperature is completely suitable for
Indoor heating demand, and temperature and running temperature are collected due to reducing, therefore system has the advantage that：Collecting efficiency is high, heat
Lose small, reduce high temperature risk, reduce device systems failure, reduce water system failure and maintenance, it is in light weight, manufacture energy consumption is low,
Cost is low, service life length, material environment friendly, while because of the present invention almost overall plastic construction, determines the environmental protection characteristic of the product,
Energy consumption is relatively low, pollution-free in the mill, and the used facilities after recovery recycle after can simply handling.
Number of devices and treatment scale described herein are the explanations for simplifying the present invention.It is double to having for the present invention
The application of the energy-storage system of warm phase transformation, modifications and variations will be readily apparent to persons skilled in the art.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With.It can be applied to this various suitable practical field completely., can be easily for those skilled in the art
Realize other modification.Therefore under the universal limited without departing substantially from claim and equivalency range, this is practical and unlimited
In specific details and shown here as the legend with description.
