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

It is applicable to various processes such as cooling, condensation, heating, evaporation, and waste heat recovery. Therefore, among the numerous categories of heat exchangers, coolers and tubular heat exchangers still hold a significant position.
