Abstract

This paper presents experimental studies on the fire behavior of fiber reinforced polymer (FRP) composite laminates and unloaded cellular FRP components with internal liquid cooling. The experiments were conducted to verify the objective of liquid cooling for improving the fire resistance of FRP composite structures for construction applications. Observations show that the pultruded E-glass/polyester composites are vulnerable under ISO-834 fire conditions, and the fire-resistance effect of charring of the resin is insignificant. Liquid cooling is demonstrated to be an efficient way to improve fire- resistance of FRP cellular construction components. With liquid cooling, cellular FRP profiles can satisfy the code requiring 90min fire resistant design time for building constructions. The cooling effect improves with increased liquid flow rates. In practice, low to moderate flowing rates (0.2-1.0cm/s) will be sufficient for improving fire resistance of FRP structures and, at the same time, can serve to heat and cool a building.

Water cooling

Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations. Water coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs and other components.

Computer cooling

Computer cooling is required to remove the waste heat produced by computer components, to keep components within permissible operating temperature limits. Components that are susceptible to temporary malfunction or permanent failure if overheated include integrated circuits such as central processing units (CPUs), chipsets, graphics cards, and hard disk drives. Components are often designed to generate as little heat as possible, and computers and operating systems may be designed to reduce power consumption and consequent heating according to workload, but more heat may still be produced than can be removed without attention to cooling.

Radiator (engine cooling)

Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plant or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called engine coolant through the engine block, and cylinder head where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine.
