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 in conjunction with the accompanying drawings.

[0014] The hot water storage tank is connected with a flat solar heat collector, the heat storage chamber 3 is filled with phase change heat storage materials, and the heating liner 7 is filled with a heat transfer medium with a low boiling point, and the heat transfer medium flows into the flat solar heat collector from the return pipe 8 The device absorbs heat. The heated and vaporized heat transfer medium enters the heating inner tank 7 from the liquid inlet pipe 4, and is liquefied by heat release. The water in the water storage chamber 6 absorbs heat from the heating liner 7 and heats up. The liquefied heat transfer medium flows back from the return pipe 8 to the flat solar heat collector. The heat storage chamber 3 protrudes from the inner wall of the water storage chamber 6, which can block the convection of cold and hot water and facilitate...

Abstract

The invention discloses a heat storage water tank. A heating inner container is arranged in the water tank; a heat-conducting medium with the boiling point of about 30 DEG C is filled in the water tank; an interlayer is arranged on the edge in the water tank; and a phase change heat storage material with the melting point of about 50 DEG C is filled in the interlayer. By adoption of the design, the circulating speed of the heat-conducting medium and the heat exchange speed of a solar thermal collector and the water tank are increased. When the temperature of hot water is higher than 50 DEG C, the water storage material absorbs and stores a great deal of heat from the hot water. When the water temperature is reduced, heat is released and the water temperature is stabilized to be 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...
