Embodiment Construction

[0017] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] During the day, the selective absorption coating on the surface of the heat storage body 4 absorbs solar radiation energy and converts it into heat energy. The phase-change heat-storage material filled inside the heat-storage body 4 undergoes heat-absorbing phase-change to store heat. Due to the thermal insulation effect of the transparent cover plate 3 and the thermal insulation shell 2, most of the heat stored in the heat storage body 4 will be retained. When the indoor temperature decreases at night or on a cloudy day and heating is required, the fan is turned on to allow cold air to flow in from the air inlet 5, and enter the room after being heated by the heat storage body 4 to increase the indoor temperature. When the temperature reaches the requirement, turn off the fan to stop heating.

Abstract

The invention discloses a solar heat storage heating device. A heat absorbing body of the device comprises a plurality of metal tubes which are closely arranged, phase-change heat storage media are filled inside the metal tubes, selective absorbing coatings are coated on the outer surfaces of the metal tubes, and solar energy can be absorbed and stored. A fan is connected to the outside of the solar heat storage heating device, so that air can flow into the solar heat storage heating device from air inlets, is heated by the heat storage body and flows into an indoor environment, and the indoor environment can be heated. The solar heat storage heating device has the advantages that the device is additionally provided with the fan, so that the air is forced to flow through the heat storage body to absorb heat, and the temperature of the indoor environment can be quickly increased; pipelines of the heat storage body are closely arranged, and the internal phase-change heat storage media can sufficiently absorb heat from tube walls, so that the heat storage efficiency can be improved.

Description

1. Technical field [0001] The invention relates to solar heat utilization and heat storage technology, in particular to a solar heat storage heating device that combines solar heat collection and phase change heat storage technology and can be widely used in buildings, agricultural greenhouses and other facilities. 2. Background technology [0002] Human beings have been using solar energy for a long time. The invention of various selective absorbing coatings and thermal insulation materials enables people to use solar energy efficiently to provide domestic hot water and building heating. However, in the field of heat storage, the level of utilization of solar energy is low, and people often use materials such as water and pebbles to store heat, such as: solar water heaters, passive solar houses. If solar energy can be absorbed efficiently and at low cost, and the heat can be stored with phase change materials for heating at night or on cloudy days, the utilization level of ...
