Heat shield
Welcome to our website. It is generaly simplier version of wikipedia. You will find there selected articles. Enjoy!
A heat shield is form a protection designed to shield a substance from absorbing excessive heat from an outside source by either dissipating, reflecting or simply absorbing the heat. It is often used as a form of Exhaust Heat Management.

Uses
Automotive
Due to the large amounts of heat given off by internal combustion engines, heat shields are used on most engines to protect components and bodywork from heat damage. As well as protection, effective heat shield can give a performance benefit by reducing the underbonnet temperatures, therefore reducing the intake temperature. Heat shield varys widely in price but most are easy to fit, usually by stainless steel clips or high temperature tape. There are two main types of automotive heat shield:
- Rigid heat shield has, until recently, been made from solid steel but is now often made from aluminium. Some high-end rigid heat shields are made out of aluminium sheet or other composites with a ceramic thermal barrier coating to improve the heat insulation.
- Flexible heat shield is normally made from thin aluminium sheet, sold either flat or in a roll and is bent by hand by the fitter. High performance flexible heat shields have been seen to include extras such as ceramic insulation applied via plasma spraying. These latest products are commonplace in top-end motorsports such as Formula 1.
As a result heat shield is often fitted by both amateur and professional personel during a phase of engine tuning.
Space
A trans-atmospheric heat shield is a protective layer on a spacecraft or ballistic missile that is designed to protect it from the high temperature of atmospheric entry, on a body with an atmosphere, such as Earth, Mars and Venus. Most, if not all, spacecraft use a type of heat shield in order to protect from the high temperatures during re-entry.
Heat shields are very important to the space shuttles and the failure of these systems can be castastrophic, as seen in the 2003 Space Shuttle Columbia disaster.
Industry
Heat shield is often used to protect heat-sensitive components used in various industrial processes.
