A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control - for example, in the case of ...
An example of a steel heat shield on a BMW E series engine Rigid heat shields have until recently commonly been made from solid steel, [5] but are now often made from aluminum. Some high-end rigid heat shields are made out of either aluminum, gold or composite, with most examples including a ceramic coating to provide a thermal barrier , which ...
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).
The key difference between a heat shield and insulating the pipe, through either wrapping or thermal coating, is the air gap that exists between the exhaust and the shield. More recently technology has become available to apply ceramic thermal barrier coatings onto flexible aluminium in order to increase the thermal insulatory properties.
The stack damper also regulates the heat lost through the stack. As the damper closes, the amount of heat escaping the furnace through the stack decreases, but the pressure or draft in the furnace increases which poses risks to those working around it if there are air leakages in the furnace, the flames can then escape out of the firebox or ...
Frictional dampers though had a mostly constant rate. This was even greater when stationary, owing to stiction between stationary plates. [1] [10] For larger bumps the damping may even be reduced. This is particularly a problem for fast driving, when repeated high forces may cause the friction plates to heat up and lose their efficiency.
Damper (food), a bread of the Australian Outback; In mechanical engineering, a damper is a device for suppressing vibrations in a mechanical system by dissipating energy. Dashpot, a type of hydraulic or mechanical damper; Shock absorber (British or technical use: damper), a mechanical device designed to dissipate kinetic energy
All mechanical systems in the real world contain some amount of damping. Damping dissipates energy in the system, which reduces the vibration level which is transmitted at the natural frequency. The fluid in automotive shock absorbers is a kind of damper, as is the inherent damping in elastomeric (rubber) engine mounts.
