The working principle of the plate heat exchanger

by:Jinzong Machinery     2020-11-04
Plate heat exchanger is a series of certain the shape of corrugated metal piled up and become a new type of high efficient heat exchangers. Thin rectangular channel formed between various plate, through half a piece of heat exchange. It compared with the conventional tube and shell heat exchanger, in the same flow resistance and pump power consumption situation, its heat transfer coefficient up to a lot of, on the applicable to replace worldwide trend of tube and shell heat exchanger. Plate heat exchanger is made from thin sheet metal pressed into a certain shape of corrugated heat exchange plate, and then fold, plywood, bolts and become a kind of heat exchanger. Working fluid between two pieces of plate formation of narrow and tortuous channel flows. Cold and hot fluid through the flow channel in turn, there is a board piece separate fluid, and through the plate heat exchanger. Plate heat exchanger structure and heat transfer principle determines its compact structure, cover an area of an area small, high heat transfer efficiency, flexible operation, wide application range, small heat loss, convenient installation and cleaning, etc. The mean temperature difference of two kinds of medium can be as small as 1 ℃, the heat recovery efficiency can reach above 99%. Under the condition of the same pressure loss, plate heat exchanger heat transfer is 3 ~ 5 times that of the shell and tube heat exchanger, which covers an area of over its one-third, metal only two-thirds of its consumption. For plate heat exchanger is a kind of high efficiency, energy saving, material saving, save investment of advanced heat exchange equipment. Plate heat exchanger is mainly composed of frame and plate of two parts. Plate made of various materials of thin plate with various forms of pressing shapes of corrugated grinding tool, and in the plate on the four corners of open hole Angle, used for medium flow. Plate of peripheral and Angle hole place with a rubber gasket to seal. Framework by the fixed pressure plate, pressure plate, upper and lower guide rod and clamp bolts, etc. Plate heat exchanger is the plate in the form of a stack in a fixed pressure plate, pressure plate, and then use fastening bolt clamping. Effect of different parts as follows: (1) heat transfer plate heat transfer plate is a major element in one of the heat transfer heat exchanger, generally made herringbone corrugated, depending on the fluid medium, heat transfer plate material is different also, mostly made of stainless steel and titanium. Second, the sealing gasket sealing gaskets of plate heat exchanger is mainly plays a role of sealing between heat transfer plate. Material has: nitrile rubber, epdm rubber, fluorine rubber, etc. , according to the different media with different rubber. Three, both ends on both ends of the pressure plate clamp is mainly clamping pressure shelter some heat transfer plate, ensure the fluid does not leak. Four, clamping bolt clamping bolt is mainly ACTS as fastening clamp on both ends. Clamping bolt is usually double thread, preloaded bolt, the fixed plate torque evenly. Five, the hanging rack is mainly supporting in hot plate, make its disassembly, easy cleaning, assembly, etc. Happy everday plate heat exchanger ( Jiangyin) Co. , LTD.
