What is a trough solar collector?
Because of the different use, the collector and its matching system type is divided into many kinds, the name is also different, such as cooking for the solar cooker, used to generate hot water solar water heater, dry items for the solar dryer, for Melting metal solar furnace, as well as solar houses, solar thermal power plants, solar desalination and so on.
A device that converts the radiant energy of the sun into heat. As the solar energy is more dispersed, must try to put it together, so the collector is a key part of the use of solar energy devices.
Due to the different expansion coefficient of glass and metal seal, this structure of the absorber is currently high cost, short life, reliability is affected.
The traditional trough solar collector device adopts the vacuum glass tube structure, that is, the inner tube adopts the metal tube, the tube takes the heating medium, the metal tube is coated with the selective absorbing coating, and then the outside is the glass tube, the glass tube and the metal pipe Vacuum to suppress convection and conduction heat loss.
As a high-temperature collector, can get a higher collector temperature, can be used for power generation, refrigeration and air conditioning, heating, desalination and other production and living areas.
