Abstract
The utility model provides a solar vacuum phase change heat storing device. The device comprises a vacuum layer outer container and a vacuum layer inner container. The air in the space between the vacuum layer outer container and the vacuum layer inner container is pumped to form the vacuum, the space of the vacuum layer inner container is filled with phase change materials, heat exchanging pipes are evenly arranged in the space of the vacuum layer inner container, the heat exchanging pipes are provided with medium outlets and medium inlets to penetrate through the vacuum layer inner container and the vacuum layer outer container, and the heat exchanging pipes, the vacuum layer inner container and the vacuum layer outer container are sealed, and the heat exchanging pipes extend outwards to form a plurality of conical heat exchanging fins. A vacuum insulating structure is adopted, the heat exchanging pipes are evenly arranged, the heat exchanging area is enlarged through the heat exchanging fins, and therefore the energy storing efficiency of the device is improved. When the consumption of the external energy is small, a hot medium enters the device to be stored, when the external portion needs the energy, the phase exchange materials emit heat, the temperature of the medium is increased so that energy can be provided for the external portion, and the solar vacuum phase change heat storing device has the advantages of being high in storing capacity and low in heat consumption.
