Cooling Jacket/Casing

A cooling jacket or casing is an engineered enclosure designed to fit around industrial equipment, particularly gas coolers, to facilitate controlled heat dissipation. It consists of a double-walled structure that creates a sealed annular space through which a cooling medium (typically water, glycol, or refrigerant) circulates. This component absorbs thermal energy from the machine's hot surfaces via conduction and convection, transferring it away to maintain optimal operating temperatures, prevent thermal degradation, and ensure process efficiency in industrial applications.

The cooling jacket operates on the principle of convective heat transfer. A coolant fluid is pumped through the annular space between the inner and outer walls of the jacket. As the fluid flows, it absorbs heat from the hot inner surface (in contact with the gas cooler) through conduction. The heated fluid is then transported away to an external cooling system (like a chiller or cooling tower), where it dissipates the heat before being recirculated. This continuous cycle maintains a stable temperature gradient, preventing overheating of the gas cooler components.
