When you construct it, follow the instructions but close the gap between screen pieces as close as possible. tesa moll® Heat reflector foil is an energy saving foil that reduces the loss of energy through the walls by reflecting the heat generated by radiators. When used in conjunction with ancillary cooling, often passive LCDs will function properly in many demanding environments. HeatShield™ filters are used to significantly prolong the function of LCDs in direct sunlight, and to reduce the thermal loading of high intensity backlights on the display. For example, an LCD will typically “brown out” if exposed to direct sunlight for extended periods of time, as the rate with which the heat is absorbed by the display often exceeds its ability to radiate this energy. Excessive thermal loading on an LCD will render the display unreadable until it cools. This makes them ideal for a variety of high-performance exterior applications, even when exposed to high humidity and strong ultraviolet light. The thermal conductivity of different types of polyethylene foam ranges from 0.029 to 0.032 W / (m K). ![]() They are hypoallergenic and safe for human health. HeatShield™ filters prolong the operation of LCDs in direct sunlight and can reduce power consumption used for ancillary cooling. Heat-reflecting screens made of insulating materials based on polyethylene foam have proven themselves best: penofol, porilex, isolona, stisol, tepofol. The reflection of the infrared radiation greatly reduces the rate at which heat will transmit through the optics into an electronic system.ĭontech HeatShield™ brand heat reflectors minimize solar loading on displays and enclosures. By design, the photopic reflections are very low in order to maintain contrast in display applications. Heat reflectors are thin film coated optics that transmit high levels of the visible spectrum (or pass band) while reflecting a dominant portion of the near. Heat reflectors are thin film coated optics that transmit high levels of the visible spectrum (or pass band) while reflecting a dominant portion of the near infrared (NIR) and IR spectrums.
