Problems solved by technology

Flat-panel solar water heaters mostly use indirect heating. Because the heat transfer medium is relatively viscous, the shape design of the heating liner or jacket is unreasonable, resulting in low heat conduction efficiency.
Moreover, the use of solar water heaters is easily restricted by weather and day and night.
[0003] At present, there are many patents on solar water heater tanks, but there is no water heater tank that can use liquid antifreeze as the heat transfer medium and the heating liner is placed horizontally inside the water tank. Discover

Embodiment Construction

[0013] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0014] The outside of the hot water storage tank is connected with a flat-panel solar collector, the heat-storage cavity 4 is filled with a phase-change heat-storage material, the heat-generating inner tank 7 is filled with a low-boiling-point heat-conducting medium, and the heat-conducting medium flows into the flat-plate solar heat collector from the return pipe 9 absorber heat. The heat-conducting medium heated and vaporized is accelerated from the liquid inlet pipe 8 through the nozzle 6, and then enters the heating inner tank 7, and hits the top of the heating inner tank 7 to release heat and liquefy. The water in the water storage chamber 2 absorbs heat from the heating inner tank 7 to heat up. The liquefied heat transfer medium is returned from the return pipe 9 to the flat panel solar collector. The heat storage cavity 4 protrudes from the in...

Abstract

The invention discloses a heat-storage water tank. A heating liner is arranged inside the water tank, a heat-conducting medium with a boiling point of about 30 DEG C is filled inside the heating liner, the water tank is provided with a scaling injection pipe, an interlayer is formed on the edge inside the water tank, and a phase-change heat storage material with a melting point of about 50 DEG C is filled in the interlayer. By virtue of the design, the circulating speed of the heat-conducting medium can be improved, and the heat exchange speed of a solar thermal collector and the water tank can be improved; and moreover, when the temperature of hot water is higher than 50 DEG C, the heat storage material absorbs a great deal of heat from the hot water and stores the heat, and the heat is released when the water temperature is reduced, thereby ensuring that the water temperature is stabilized at about 50 DEG C.

Description

technical field [0001] The invention relates to solar heat utilization technology and phase change heat storage technology, in particular to a hot water storage tank used for solar water heaters. The water tank is provided with a heating liner, and the edge of the water tank is provided with an interlayer filled with phase heat storage material. Background technique [0002] In the field of solar thermal utilization, solar water heaters have appeared in a variety of mature products including vacuum tube water heaters and flat plate water heaters. Flat plate solar water heaters are rapidly opening up the market due to their longer service life and easy installation methods. Flat-panel solar water heaters mostly use indirect heating. Because the heat transfer medium is relatively viscous, the shape design of the heating liner or jacket is unreasonable, resulting in low heat conduction efficiency. Moreover, the use of solar water heaters is easily restricted by weather and day...
