Shandong Youkun Energy Equipment Co., Ltd. is a manufacturer of heat exchangers, including plate heat exchangers, volumetric heat exchangers, spiral tube heat exchangers, annular tube heat exchangers, floating tube heat exchangers, low-pressure heat exchangers, and heating heat exchangers. The company's main products include nine categories: heat exchangers, plate heat exchangers, heat exchanger units, pressure vessels, boiler auxiliary equipment, water supply equipment, water treatment equipment, reverse osmosis devices, wastewater treatment equipment, and fully intelligent oil/gas/electric boilers. Heat exchangers, plate heat exchangers, and heat exchanger units are suitable for sanitary hot water in residential areas, government offices, factories and mines, hospitals, hotels, and schools. Integrated heat exchanger units can be used for water-to-water exchange or steam-to-water exchange. For high-quality heat exchanger units, Youkun is a trustworthy choice.
A plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal plates with a certain corrugated shape. Thin rectangular channels are formed between the plates, allowing for heat exchange through the plates. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. They feature high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure loss, their heat transfer coefficient is 3-5 times higher than that of tube heat exchangers, the footprint is one-third that of tube heat exchangers, and the heat recovery rate can be as high as 90% or more. Plate heat exchangers are mainly divided into two categories: frame plate heat exchangers (dismountable plate heat exchangers) and brazed plate heat exchangers. The main types of plates include chevron corrugated plate heat exchangers, horizontal straight corrugated plate heat exchangers, and dimpled plate heat exchangers.
Plate heat exchangers are classified by structure: dismountable plate heat exchangers (also known as plate heat exchangers with gaskets), welded plate heat exchangers, spiral plate heat exchangers, and plate and shell heat exchangers (also known as honeycomb heat exchangers).
According to process applications, there are different names: plate heaters, plate coolers, plate condensers, and plate preheaters;
According to process combination, they are divided into single-pass plate heat exchangers and multi-pass plate heat exchangers;
According to the flow direction of the two media, they are divided into co-current (parallel flow) plate heat exchangers, counter-current plate heat exchangers, and cross-flow (cross-current) plate heat exchangers, with the latter two being more commonly used;
According to the size of the flow channel gap, they are divided into conventional gap plate heat exchangers and wide gap plate heat exchangers;
According to corrugations, plate heat exchangers have more detailed classifications, which will not be elaborated here. Please refer to: Plate heat exchanger plate corrugation forms.
According to whether they are complete sets of products, they can be divided into single-unit plate heat exchangers and plate heat exchanger units.
Plate heat exchangers are widely used in metallurgy, mining, petroleum, chemical, power, pharmaceutical, food, chemical fiber, papermaking, light textile, shipbuilding, and heating industries. They can be used for heating, cooling, evaporation, condensation, sterilization, disinfection, and waste heat recovery.
