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.
