Energy-storage solar heat collector

Abstract

The invention belongs to the field of utilization of solar sources, and particularly relates to an energy-storage solar heat collector. The energy-storage solar heat collector comprises a solar glass evacuated solar collector tube (1), an energy-storage rod (2), a heat exchange tube (3), a flow guide pipe (4), a water outlet main pipe (5), a water inlet main pipe (6), an insulating layer (7) and a shell (8), wherein the energy-storage rod (2) is arranged inside the solar glass evacuated solar collector tube (1) and filled with heat storage materials, the heat exchange tube (3) is arranged in the energy-storage rod (2), the flow guide pipe (4) is arranged in the heat exchange tube (3), the heat exchange tube (3) is connected with the water outlet main pipe (5), the flow guide pipe (4) is connected with the water inlet main pipe (6), the water inlet main pipe (6) is arranged in the water outlet main pipe (5), the insulating layer (7) is arranged outside the water outlet main pipe (5), and the shell (8) is arranged outside the insulating layer (7). The energy-storage solar heat collector ensures that the heat storage material is completely separated from water, and solves the problem of damage of the phase change material to the solar heat collecting tube during the phase change process.

Description

technical field [0001] The invention relates to the field of solar resource utilization, in particular to an energy storage type solar heat collector. Background technique [0002] The current solar collectors used to provide domestic hot water or heating are mainly vacuum tube collectors and flat plate collectors. Vacuum tube collectors have relatively high heat collection efficiency, relatively high heat collection temperature, and relatively high heat loss. Less, widely used. Generally, solar heat collection cannot be used with the collection, and a heat storage device is often required. At present, most solar heat storage devices are solar water storage tanks. Water heat storage mainly relies on the sensible heat of water. The demand is large, and when the weather or season changes, the water temperature in the solar thermal storage tank changes greatly, the installation of the water thermal storage solar water heater is greatly restricted, and the heating quality is no...
