Coolers are a type of heat exchange equipment used for cooling fluids. They typically use water or air as cooling agents to dissipate heat. Mainly, they can be categorized into tube bundle coolers, plate coolers, and air-cooled coolers. Coolers are widely used as heat exchange devices in various industrial sectors such as metallurgy, chemical industry, energy, transportation, light industry, and food processing.

It is suitable for various processes including cooler, condenser, heating, evaporation, and waste heat recovery. Therefore, among the numerous types of heat exchangers, coolers and tubular heat exchangers still hold a significant position.
