Problems solved by technology

[0002] The water level of solar heat storage water heaters is generally higher than that of collectors, which requires water supply from water towers, which is not easy to manage and maintain; although there are improvements, the cost has been greatly increased
Dish reflector solar cooker can boil water and cook, but the operating environment is not good, and the function is single
Due to the low energy density of solar energy, solar collectors heat up a large amount of working fluid slowly, especially under transient solar irradiation conditions; this is not conducive to improving the thermal energy density of working fluid and the storage and utilization of thermal energy
In fine weather, the heat energy collected by solar collectors during the day cannot be fully utilized in most cases, especially in household applications

Abstract

The invention discloses a device using photothermal solar energy. Solar irradiation ensures that the temperature of a solar heat collector with thermal capacity of a heat-carrying working medium reduced rapidly rises, and thermal energy density of the heat-carrying working medium is improved in a wide range. Thermal energy is transmitted to a heat exchanging pipe 5 in an insulated water box 4 by the heat-carrying working medium after passing through a constant-speed spiral line metal coil of a heating stove 8, a heat-storage heat exchanging pipe of a heat-storage insulated barrel 904 and a heating pipe 601 of a thermodynamic pump 600. The heat-carrying working medium does one-way closed-cycle operations in the device. Natural circulation or compulsory circulation of the heat-carrying working medium ensures that installment positions of the insulated water box 4 and the like are easy to select and accordingly convenient to manage and maintain. The device using the photothermal solar energy is not high in technical requirement, easy to manufacture and low in cost, and has the advantages of supplying hot water, boiling water, cooking, improving the environment where heat energy is utilized, accumulating heat, preventing freezing, being energy-saving and environment-friendly and the like.

technical field [0001] The invention relates to the technical field of solar thermal application. Background technique [0002] The water level of the solar heat storage water heater is generally higher than that of the collector, which requires water supply from the water tower, which is not convenient for management and maintenance; although there are improvements, the cost has been greatly increased. The dish reflector solar cooker can boil water and cook, but the operating environment is not good, and the function is single. Due to the low energy density of solar energy, solar collectors are slow to heat up a large amount of working fluid, especially under transient solar irradiation conditions; this is not conducive to improving the thermal energy density of the working fluid and the storage and utilization of thermal energy. In fine weather, the heat energy collected by solar collectors during the day cannot be fully utilized in most cases, especially in household app...
