Biodegradable infrared emission passive radiation cooling structure and cooling method

Abstract

The invention discloses a biodegradable infrared emission passive radiation cooling structure and cooling method. The biodegradable infrared emission passive radiation cooling method comprises the steps that ethyl cellulose, ethyl alcohol and water are mixed and stirred to form a premise solution; the premise solution is put into a container, the ethyl alcohol is evaporated, the ethyl cellulose and the water are separated, micropores are formed in the ethyl cellulose, and a cooling material layer is formed; the cooling material layer is adhered to the surface of a heat transfer material layer;the cooling material layer is covered with a layer of material plate with the high light transmittance, and the material plate serves as a protection layer; a heat insulation cavity layer is formed between the cooling material layer and the protection layer; the heat transfer material layer, the cooling material layer, the heat insulation cavity layer and the protection layer form the passive radiation cooling structure, and the heat transfer material layer makes contact with a cooled body; and the protection layer is exposed outdoors. According to the biodegradable infrared emission passiveradiation cooling structure and cooling method, environmental protection is facilitated, the problem that refrigerating energy consumption is high or active refrigerating can not be adopted can be solved, and meanwhile the problems that a common chemical material can not be regenerated and greatly influences the environment are solved.

Description

technical field [0001] The invention relates to the field of cooling, and more specifically relates to a biodegradable infrared emitting passive radiation cooling structure and cooling method. Background technique [0002] At present, many fields need to cool down, including construction, industry, electronics, mechanical equipment, etc. For example, when the outdoor temperature of a building is high, air conditioners are needed to cool down; in the absence of air conditioners, electric fans or water evaporation are used to cool down. In the field of mechanical equipment, the equipment will emit heat after operation, and the temperature will affect the operating efficiency of the equipment to a certain extent, so it must be cooled. [0003] The above fields all consume a certain amount of electric energy. In order to save energy or in some occasions where active cooling methods cannot be used, passive cooling materials can be used to cool down. But ordinary passive cooling...
