Material temperature degree), the working medium gas phase condensation heat release that hot-fluid is conducted in fluid, shell clearance by inner tube 1 tube wall, condensed fluid 4
Flow down along inner tube 2 outer wall landing, enter in evaporation tube 3 and flow down along inwall, during flowing down, absorb in phase-changing energy storage material
Heat and evaporate, the gas-phase working medium of evaporation along evaporation tube flow up arrive sleeve structure heat exchanger inner tube 1 outer wall, meet cold flow
Condensation, heat is conducted to heated fluid by inner pipe wall, goes round and begins again, it is achieved heat is from vacuum heat collection pipe thermal-arrest--phase transformation
Material energy storage--it is heated the conversion of this energy of fluid and utilizes process.
Apparatus of the present invention, with solar energy as thermal source, utilize the hot superconducting heat collection of fin and heat cycles dry air, efficiently give up
Heat recovery exchanger, has baking temperature high and constant, and convection drying speed is fast, and compact conformation, heat accumulation heat supply temperature is constant (complete
Energy storage material fusing point is entirely had to determine), solar energy time balanced use, user heats immediately, and firing rate is fast, safe and reliable, makes
By the feature such as convenient, can be not only used for solar energy family life hot water supply, and can be widely applied to solar boiler, too
Sun can the field such as heating, four seasons sun glasshouse.
