Problems solved by technology

However, the heat storage plate with this structure generates a large amount of excess heat under the condition of sufficient sunlight during the day, which is directly transmitted to the inside of the greenhouse, resulting in high daytime temperatures in the greenhouse and buildings requiring ventilation and heat release; its heat storage effect is poor, and the nighttime temperature is low When it is necessary to add heat, and the production cost is high

Abstract

The invention discloses a heat accumulation plate formed by mutually splicing an outer surface layer, an intermediate layer and an inner surface layer, wherein the outer surface layer (1) and the inner surface layer (3) are both metal plates; the intermediate layer (2) is made of material with smaller heat capacity ratio or insulation; holes (4) are formed on the surface of the intermediate layer (2) and are filled with a heat accumulation medium (5) with higher heat capacity ratio; the intermediate layer (2) is one of polyurethane plate, polystyrene plate, wood plate and foam plate; and the heat accumulation medium (5) is water or sodium sulfate decahydrate. The heat accumulation plate can absorb a large amount of excess heat into a heat accumulation medium generated by sufficient sunlight at daytime and avoid the phenomenon that greenhouses and buildings are required to ventilate and discharge when the air temperature is higher at daytime; and the heat accumulation medium releases the heat accumulated at daytime when the air temperature at night is low without supplementing the heat. The heat accumulation plate disclosed by the invention has the advantages of low production cost, favorable heat accumulation effect, energy saving and environmental protection.

Description

technical field [0001] The invention relates to a heat storage plate, in particular to a heat storage plate containing a material with relatively large heat capacity as a heat storage medium. Background technique [0002] At present, heat storage panels widely used in solar greenhouses, buildings and other walls are composed of an outer heat insulation layer, a middle heat storage layer and an inner air permeable and water permeable layer. The heat storage layer is made of materials with air permeability, water permeability, toughness, rigidity, and heat storage function, and the inner air-permeable and water-permeable layer is made of materials with good air permeability and water permeability. However, the heat storage plate with this structure generates a large amount of excess heat under the condition of sufficient sunlight during the day, which is directly transmitted to the inside of the greenhouse, resulting in high daytime temperatures in the greenhouse and buildings...
