Definition - What does Jacket Water mean?
Jacket Water is a casing that circulates or holds water around a device so that it can be cooled, heated or kept at a constant temperature. It is a metallic sheath which contains outlet and inlet vents that allow water to be circulated or pumped through. The water flowing to some external cooling or heating device helps in controlling the temperature of the device. It also helps in:
- Minimizing heat that gets exchanged with the environment.
- Reducing the bearings temperature.
- Eliminating the requirement of forced ventilation.
- Reducing noise and maintenance.
Petropedia explains Jacket Water
The engine and other parts which are exposed to high temperatures are required to be cooled as they can be damaged due to the burning fuel. Jacket Water is the most effective cooling system which is used for maintaining the temperature of the engine at a desirable limit. It contains water circulation via frame and end shields. The motor and water do not exchange heat but instead it is the system which increases the output and weight ratio by reducing the temperature of the conducting materials. Jacket Water is often used for water cooling in laboratory glassware such as Graham, Leibig and Allihn condensers. It is used for conserving heat and therefore increasing probability.
