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.

This preserves the valuable surface area on the sides of the block for mounting bosses and cast-in features while stiffening the area of connection to the cylinder wall, all while maintaining the desired water jacket cross sectional size.
the module having pin-fin type water jacket [5] [6]) and the direct-cooled module prototype with a thick Cu heat spreader are shown in Figure 6.
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.
Therefore, a proper design scheme for water jacket and pretightening process is required to reduce such distortion.
11x59R, Its air-cooled jacket was replaced by a crudely repaired water jacket.
There are other options available--just make sure you can install a water jacket.
First show for new LR 5500 cooler with 90-psi-rated water jacket for more efficient cooling.
The switch can be mounted in a series of locations such as the engine water jacket or hydraulic oil tank, and is typically installed as a single unit but can be used in two- or three-unit configurations to control and monitor multiple functions.
In addition, the water jacket sleeve now remains attached to the viscometer while the chamber and/or spindle are removed.
The housing can be constructed in one of three different ways: (1) heat sink with ambient-air convection cooling, (2) heat sink with forced air (electrical fan) cooling, or (3) water jacket cooling [5].
Standard features include bimetallic-lined barrels, cast aluminum heat/cool jackets, high-capacity blowers, double reduction gear boxes with incorporated taper roller thrust bearings, cast-iron feed throats with incorporated water jacket, quick-adjust motor belt tightening features, and Colmonoy-hardened plastification screws.
