Phase-change and heat-storage solar water heater

Abstract

The invention discloses a phase-change and heat-storage solar water heater comprising a fixed support, wherein a plurality of vacuum tubes are fixed on the fixed support and internally provided with heat tanks (heat storage elements); inorganic phase change materials and heat exchange water flow pipelines are arranged in the heat tanks (heat storage elements); and a flow channel header box is fixed at one side of the fixed support, internally provided with a water inlet pipe and a water outlet pipe and filled with heat insulation materials. The phase-change and heat-storage solar water heater has a simple structure, is convenient to install, high in heat efficiency of a system and easy in building integration, runs by bearing pressure, and overcomes the defects that a common solar water heater has a heavy appearance, occupies a large space, and is difficult in building integration, emptying and control, the accumulated water in the common solar water heater deteriorates, and the like.

Description

technical field [0001] The invention belongs to the field of solar water heaters, in particular to a phase change heat storage solar water heater. Background technique [0002] Existing ordinary solar water heaters have complex structures, clumsy shapes with water tanks, difficulty in building integration, difficulty in installation, low heat conversion capacity, and fundamental difficulties such as emptying, control and deterioration of water quality, and cannot be popularized and used. , especially in urban environments. [0003] Although the split type water heater overcomes some shortcomings, it still takes up a lot of space, sacrifices system efficiency and greatly increases costs, making it difficult to apply in large quantities. Contents of the invention [0004] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a phase-change heat storage solar energy system with high thermal efficiency, simple structure and ...
