Plate heat exchangers are partially heat transferred to cold fluid equipment, also known as plate type heat exchangers. Plate heat exchangers are commonly used in many industrial sectors such as chemical, petroleum, steel, and automobiles, and occupy an important position. Especially in chemical production, plate heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers etc. It has a high heat transfer coefficient, small pressure drop, compact structure, light weight, small footprint, convenient combination of area and process, strong versatility of parts, wide choice of materials and easy to achieve large-scale production. It has been widely used in food, machinery, metallurgy, petrochemicals, and ships.
