Urban heat island effect relief mirror and production method thereof

Abstract

An urban heat island effect relief mirror is composed of an insulation board 1 and concave mirror 2 which are integrated. A plurality of blocks of concave surfaces are formed on the insulation board in a pouring or vacuum aluminum plating method, and then a layer of reflective materials are coated on the concave surfaces to form the concave mirrors. The concave mirrors are fully distributed on the outer surface of the insulation board in a step mode. During use, the urban heat island effect relief mirror is attached to outer walls and roofs of buildings or the grounds, the insulation board is used for heat preservation, and the concave mirrors are used for reflecting sunshine. The concave mirrors have a sunshine converging effect and inwards refract the reflected light rays so that when sunshine illuminates to the concave mirrors on the buildings, the reflected light stays away from the buildings due to inward refraction and instead spreads to the space, radiation of urban sunshine is reduced, and accordingly the urban heat island effect is reduced. The urban heat island effect relief mirror improves the current hot situation of cities, balances the temperature differences between cities and suburbs, prevents suburban pollutants from entering cities, and accordingly relieves urban air pollution.

Description

technical field [0001] The urban heat island effect mitigating mirror belongs to the field of environmental protection, specifically a kind of urban heat island effect mitigating mirror. [0002] Background technique [0003] The situation of global air pollution and "heat island effect" is very serious. In terms of air pollution, it mainly presents the characteristics of soot-type pollution: the concentration of total suspended particulate matter in the urban air environment generally exceeds the standard; sulfur dioxide pollution remains at a relatively high level; The amount of nitrogen oxides has increased rapidly; nitrogen oxide pollution is showing an aggravating trend. In terms of "heat island effect", with the rapid expansion of city scale (population, area, building height and concentration) and the serious air pollution, the city's "heat island effect" is becoming more and more obvious. Under the action of the "heat island effect", the temperature in each place i...

Problems solved by technology

However, these measures are very limited in mitigating the "heat island effect", and these technologies and measures are for the control of air pollution, smog sources and individual parts of the "heat island effect", rather than overall and comprehensive control
