The Application of Radiation Cooling Coating to LED thermal imaging
.Product overview
Radiation Heat Cooling Coating is a kind of coating that radiate heat, which could send out the heat from the objects in the form of 1-13.5μm
Wave length so that to low the temperature of inside and outside of objects. It can be used in vacuum environment and not subject to surroundings What’s more it has obvious effectiveness in heat cooling. When performing the function of radiation heat cooling, the coating is of the characteristics of self-cleaning property, non-corrosibility, waterproofness, fireproofing, insulativity, acid and alkali stability and constructing convenience etc.
.Working principle
Radiation heat cooling coating adopts high-performance cooling solution, which is of some special performance such as high visible light, near infrared reflectance, thermal infrared emissivity and stability. Meanwhile It is of good physical and chemical properties as well as application property and various compound performance.
The working principle of this radiation solution is to produce binding force by the condensate of inorganic colloidal particles(less than 100nm). The addition of materials as carbon nanotubes which of high pyroconductivity and radioactivity increased the coefficient of thermal conductivity. The nonmaterial component that make the coating surface smooth in macro view and rough in micro view could greatly increase the contact area of heat sink with outside, reduce the heat shield, significantly increased the cooling effect.
At the same time, the adding of large quantity of various spinel as Composite infrared radiator, which is transited by electron not only increased the impurity level, improved the coefficient of infrared radiation but also keeping the excellent performance such as corresponding thermal stability, heat resistance, high strength, corrosion resistance and abrasion resistance.
In order to overall improve the strength and stability of cooling coating, we also add Rare Earth Oxide in it to improve the activity of coating composition. REO is the preferred material for doping and stabilizing coating structure.
Main Characteristics :
1.Radiation heat cooling coating is of high thermal conductivity and large cooling surface area.Meanwhile within a wide wavelength range (1-20μm), it has high emissivity, which can significantly improve the compound performances as conduction, convection and radiation cooling.
2.Radiation heat cooling coating can operate steadily in high temperature, including thermal and chemical stability, good weather resistance and Acid and alkaline resistance.
3.Radiation heat cooling coating can strongly combine with metal and ceramic substrate. It has enough mechanical strength, toughness and will not peel off by the suddenly change of temperature.
4.Radiation heat cooling coating is of good coating process, which make performance easy and convenient. It can protect the objects in the long run due to its characteristics of abrasion resistance, shock resistance and long service life.
5.Radiation heat cooling coating is a new type of environmental and energy saving coatings. It does no harm to human body before and after construction.
