water jacket

[′wȯd·ər ‚jak·ət]
A casing for circulation of cooling water.

Water Jacket


a cavity that surrounds the parts of machinery and equipment (internal-combustion engines, metallurgical furnaces, and so on) that are exposed to intense heat and that is designed to contain a circulating liquid coolant. To avoid clogging of the water jacket by hard-to-remove deposits, the water used for cooling is sometimes subjected to preliminary purification and softening.

Note that for the engine, since the water jacket is split into two domains, the calculated total source of heat generated is appropriately partitioned for the two domains, divide it by the respective volumes of the two domains, and then assigned to the domains as source per volume term.

The check valve used in the lower thermosiphoning line that runs from the drum to the lower water jacket inlet is important, and keeps the heated water from backing up in an opposite direction from what we want.

Customer wants for cylinder blocks include: * reduced weight through improved dimensional control, thinner walls and nearer net shape; * more compactness through reduced sand sections in the water jacket core; * reduced cost through improved processing and cast-in features;
The impact that product features like these have on the foundry can best be explained by looking at the water jacket core.
