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

A kind of heat accumulation plate

Technical field

The present invention relates to a kind of heat accumulation plate, the heat accumulation plate of the bigger material of heat capacity ratio as heat storage medium contained in particularly a kind of centre.

Background technology

At present, the heat accumulation plate that is widely used in bodies of wall such as heliogreenhouse, building is made up of appearance insulating, middle recuperation layer and Nei Biao air-and water-permeable layer, its appearance insulating is to be made of heat-barrier material, middle recuperation layer is made of the material with gas permeability, water permeability, toughness, rigidity, heat accumulation function, and interior table air-and water-permeable layer is that the material by, gas permeability, good water permeability constitutes.But under the sun-drenched by day condition of the heat accumulation plate of this structure, produce excessive heat, be directly passed to inside, greenhouse, cause greenhouse and building daytime temperature height to need ventilation, heat release; Its accumulation of heat weak effect when nighttime temperature is low, needs additional heat, and the cost of production height.

Summary of the invention

At problems of the prior art and defective, the object of the present invention is to provide that a kind of heat storage capacity is strong, cost of production is low, dismounting is convenient, the heat accumulation plate of energy-conserving and environment-protective.

For the purpose technical scheme that realizes foregoing invention is: a kind of heat accumulation plate, it is pasted mutually by extexine, intermediate layer and endosexine and forms, described extexine is a metal sheet, described endosexine is a metal sheet, it is characterized in that, described intermediate layer is the less or thermal insulation material of heat capacity ratio, is distributed with hole on its surface, and the bigger heat storage medium of heat capacity ratio is housed in the hole.

Described intermediate layer is polyamine fat plate, polyphenyl plate, plank, cystosepiment.

Described heat storage medium is water, sal glauberi.

The operating principle of Ben Mingfa heat accumulation plate:

The principle different according to the different material specific heat capacity, less or thermal insulation material is as the intermediate layer with heat capacity ratio, be provided with the hole of certain diameter or size on the less or thermal insulation material in heat capacity ratio, the bigger material of heat capacity ratio packed in the hole as heat storage medium, and (solid dielectric can directly be packed into, liquid medium can seal with packaging bag, pack into then), material surface forms heat accumulation plate with the high metal sheet face sealing of the coefficient of heat conduction.The excessive heat that produces when heat accumulation plate is can be with daytime sunny sucks in the heat storage medium, can not cause greenhouse and building daytime temperature height to need ventilation, heat release, the heat that heat storage medium will hold daytime when nighttime temperature is low has discharged, and does not need additional heat.

Heat accumulation plate of the present invention is mainly used in body of wall accumulation of heats (example: Assembly greenhouse, pig house, cowshed, hen house and other building) such as heliogreenhouse, building.

Heat accumulation plate cost of production of the present invention is low, accumulation of heat is effective, energy-saving and environmental protection.
