Automotive cooling

Additions of cadmium (0.05—1.3%) to copper raise the recrystallization temperature and improve the mechanical properties, especially in cold-worked conditions, with relatively Htde reduction in conductivity. Copper containing 0.07% cadmium is used in automotive cooling fins, heavy-duty radiators, motor commutators, and electric terminals. [Pg.389]

Antifreeze. Any compound or mixture that lowers the freeing point of water can be referred to as antifreeze. The preponderant, commercial antifreeze is ethylene glycol diluted with water. Other organic compounds used occasionally are methanol, ethanol, and propylene glycol. The primary application is to protect automotive cooling systems from freezing. [Pg.391]

The thermostatic bimetal approach is used widely in a variety of Ihermosiaiic-lype temperature-control situations, as found in healing and air-conditioning systems and in automotive cooling systems, among others. Bimetals are also used in thermal type time-delay relays and switches. [Pg.200]

Ethylene glycol has important commercial uses. It is an excellent permanent antifreeze for automotive cooling systems because it is miscible with water in all proportions and a 50% solution freezes at —34° (—29°F). It also... [Pg.647]

Ethanediol (ethylene glycol) is a familiar antifreeze. However, it also is used in automotive cooling systems in climates that rarely, if ever, reach temperatures at which water would freeze. What other function, as important as lowering the freezing point, does the diol serve when added to automotive cooling systems ... [Pg.670]

Water treeing arises with polyethylene insulated cables in wet conditions and at modest voltages where water diffuses into the insulation and, under particular conditions, forms fine chaimels. Wright (9) notes that this has also been seen in EPDM rubbers and he also cites a case of automotive cooling hose where a voltage was apparently generated by electrochemical processes between the coolant and metals in contact with the coolant. This makes a good example of a case where the most unexpected occurred. [Pg.15]

Polypropylene is used in a very wide range of applications from pipes for chemical plant to automotive cooling fans and tool handles. [Pg.45]
