Embodiment Construction

[0015] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0016] In the solar heat collector with stacked heat storage, when the sun is sufficient, the solar heat collector heats the heat conduction medium, enters the heat conduction medium layer 7 from the medium inlet 8, and heats the phase change storage in the heat storage material layer 6. hot material. The heat-conducting medium that dissipates heat and cools returns to the solar collector from the medium outlet. Cold water flows into the water layer 5 from the water inlet 2 at night, absorbs heat from the heat storage material layer 6, and becomes hot water and flows out from the water outlet 4. The phase change heat storage material in the heat storage material layer 6 absorbs heat during the day and undergoes phase change to store heat, and releases heat to heat water at night.

Abstract

The invention discloses a laminated heat-storage device comprising a water layer, a heat-storage material layer and a heat conductive media layer which are stacked sequentially from up to down in a circulating manner. Water, heat conductive media and phase-change heat storage material are contacted and exchange heat through a large metal plane, and heat exchanging area is increased. The entire device can be designed to be rectangular, structure is compact, and space is saved.

Description

1. Technical field [0001] The invention relates to the field of solar heat utilization, in particular to a laminated heat storage device. 2. Background technology [0002] A solar water heater is a solar energy utilization device that uses solar energy as an energy source to heat water or a heat transfer medium. Existing solar water heater products are divided into integral solar water heaters and split solar water heaters according to installation methods. Integral solar water heaters can only be placed on roofs and roofs, and have certain requirements for the top area of ​​buildings, which cannot meet the needs of high-rise buildings. The split-type solar water heater has a relatively large water tank, and it will take up a relatively large space when installed in a bathroom, balcony or kitchen. [0003] A thermal storage solar water heater has appeared (application number: 201220417779.3), which describes a thermal storage solar water heater, including a vacuum tube dev...
