It is conducted to metallic tin（Or tin alloy）0-2-1.
The money saving function of heat energy：To make hot systems keep stable, operating mode in a balanced way, photothermal converter to be provided simultaneously with accumulation of heat work(
Energy.Heat accumulation function experiences solid-liquid state change in phase transition temperature by ternary chloride and realizes.
Ternary chloride is mixed according to a certain percentage by potassium chloride, Sodium Chloride and magnesium chloride, is allowed to phase transition temperature and is close to
400°C.So that its expiration and inspiration heat energy by solidification, fusing near the temperature, maintains unit temp stable.
Binary fluid heat-carrying agent（Including 0-2-1,0-2-2）Itself thermodynamic cycle transporting heat energy：To adopt solar energy
The heat energy that collection transmitting device is collected realizes wide temperature range（Low temperature-middle temperature-high temperature）Transmission, improves the thermodynamics effect of thermal power machinery
Rate, reduces the kinetic energy consumption of heat energy conveying, maintains hot systems stable operation.Photothermal conversion device adopts conduction oil 0-2-2 and gold
Category stannum（Or tin alloy）0-2-1 binary fluids heating agent conveys heat energy.Whole hot systems are enable from room temperature to 1200C °
Normal work in wide temperature province, is gathered and in fluid heat carrier medium 0-2 under different illumination conditions with adapting to whole hot systems
Transporting heat energy during different temperatures.Device is in low, middle temperature（Less than 400C °）Interval fluid heat carrier medium can adopt conduction oil 0-2-2；
In high temperature（Higher than 300C °）Interval fluid heat carrier medium 0-2 can adopt metallic tin（Or tin alloy）0-2-1.300C ° to 400C °
Between be two kinds of fluid heat carrier medium handover operation temperature ranges.Two kinds of fluid heat carrier medium handover operation temperature ranges of system
It is defined by the temperature measured by temperature sensor 5-4.
Because binary fluid heat-carrying agent is to realize switching with indifferent gas under photothermal converter inner sealing environment, therefore conduction oil
0-2-2 and metallic tin（Or tin alloy）0-2-1 will not occur oxidation deterioration.
The system operation principle of photothermal converter：Middle temperature phase change heat storage material under normal temperature state, in photothermal converter
Ternary chloride 0-1 and metallic tin（Or its alloy）0-2-1 is solid-state, and conduction oil 0-2-2 is liquid.
When light hot receiver receives and spread out of heat energy, metallic tin is directly heated in heating chamber 1-2（Or its alloy）0-2-1.
Metallic tin（Or its alloy）While by thermal energy conduction to the ternary chloride 0-1 in accumulation of heat exocoel 1-1 and circulation after 0-2-1 heats up
Conduction oil 0-2-2 in epicoele 1-3.When conduction oil 0-2-2 reaches uniform temperature, start along circulating line setting path from
It is dynamic to circulate.Electromotor is sent out for CETRINE and uninterruptedly conveys heat.
When Jing conduction oils 0-2-2 heating reaches metallic tin melt temperature, metallic tin（Or its alloy）0-2-1 melts first
Accumulation of heat simultaneously has mobility simultaneously.When circulating heat conduction oil 0-2-2 temperature stabilizations are higher than metallic tin（Or its alloy）0-2-1 fusing points with
During upper uniform temperature, start compressor（Inertia air pump）4, aspirate the noble gases 0-3 in balance bunker 3 and pass through inert gas tube
Road 4-1 is compressed into the indifferent gas gap 1-4 in heating chamber 1-2.By metallic tin（Or its alloy）0-2-1 is expressed to circulation epicoele 1-
3, take over conduction oil 0-2-2 Automatic Cycle conveying heat.System is realized in middle temperature and is progressively transitioned under the condition of high temperature running.Quilt
The conduction oil 0-2-2 for displacing is by metallic tin（Or its alloy）0-2-1 is forced in balance bunker 3.
Work as metallic tin（Or its alloy）When 0-2-1 reaches 400 C °, the ternary chloride 0-1 in thermal 1-1 start by
Step melts heat absorption, saves peak value heat energy.
After the ternary chloride 0-1 in thermal 1-1 all melts, system temperature continues to raise, and maintenance system is in
Temperature is simultaneously progressively transitioned into condition of high temperature operation.
Heat reduction is given when extraneous, when system temperature is less than 400 C °, ternary chloride 0-1 then heat release solidifications first, solidification
Institute's liberated heat is to continue heat supply with hot spot, and the system of maintenance is run in middle temperature state；Metallic tin is reduced in temperature（Or its
Alloy）Before 0-2-1 freezing pointes, system is switched to conduction oil 0-2-2 circulation patterns.This is kept with the mode of switching thermal medium
Special woods electromotor and whole hot systems are in wide temperature range stable operation.
Binary fluid thermal medium 0-2 in photothermal converter promotes metal with the compression indifferent gas 0-3 that compressor 1-4 is provided
Stannum（Or its alloy）Mutual switchover operation between two medium of 0-2-1 and conduction oil 0-2-2.
To reduce the armamentarium of thermal loss, photothermal converter and its correlation, pipeline, effectively insulating tightly must be set
Layer.
Photothermal converter must be placed lower than the position of the conjuncted machine of CETRINE generating-heat pump；4 palpus of balance bunker 3 and compressor
Installed in the position higher than photothermal converter and Stirling engine.
Because the position of photothermal converter is far below Stirling engine expanding end heater 7, therefore fluid heat carrier medium Jing light
After the heating expansion of hot receiver 2, by itself heat power to high bit flow, in the expanding end heater into Stirling engine
After 7, mechanical energy is converted heat into and contraction of lowering the temperature.Because Stirling engine expanding end heater 7 is in a high position, therefore cooling is received
Fluid heat carrier medium after contracting itself heat power reduces and settles to low level.After photothermal converter accumulation heat is flowed through, then connect
Light hot receiver 2 is heated and enters subsequent cycle.
The potential difference that fluid heat carrier medium is disposed by equipment, utilizes hot, forms itself heat power to the thermogenetic temperature difference
Circulation.Outer powered has been broken away from thoroughly.Power consumption can both have been reduced, be avoided that again because power-equipment wear and tear and occurs leak with
Mechanical breakdown.So as to realize economic, safe, the long-acting operation of hot systems device external power-free.
