New material can make solar collector temperature rise to 220 degrees Celsius

Us researchers have developed a latest cost-effective new aerogel material, used for solar collector to improve collection efficiency, keep the temperature at 220 degrees Celsius.

after the roof of the home use collector can only be water heated to 80 degrees Celsius, and use new aerogel materials collector can keep temperature at 220 degrees Celsius, the residential heating and food processing and other fields has a broad application prospect.

the principle of solar collector is to let more light on the black heat absorbing material and try to avoid heat dissipation, typically between black heat absorbing material with a layer of glass manufacturing vacuum for insulation, but the manufacturing cost is higher.

the scientific research team at the Massachusetts institute of technology recently in the journal of American chemical society & middot; Nano journal reports, they developed this almost completely transparent new light aerogel, but on the premise of guarantee heat insulation performance, transmission of 95% of the incident sunlight. After only about 70% light transmittance of similar materials.

aerogel material is a kind of foam materials containing silicon dioxide particles. Compared with the traditional aerogel, between the new type of the aerogel particles formed more intensive pore, to a greater degree to reduce the scattering of light, without the light focus at some point, the collector temperature can be increased to 220 degrees Celsius.
