Plate heat exchanger mat
The plate heat exchanger is a highly efficient and energy-saving heat exchanger, which has many advantages such as high heat transfer coefficient, compact structure, low consumption, diversified appearance, easy maintenance, The application field is gradually expanding and has been widely used in machinery, electricity, industries and fields such as metallurgy, chemical, textile, beverage, and urban heating have been shows strong competitiveness. Plate changer pads are made of sheet metal (typically 5-10mm thick) as pad change elements, pressed from thin sheets of stainless steel, industrial pure titanium or other other materials. Usually, people use a plate die to press the plate into a groove or wave shape, which can increase the stiffness of the plate so that the plate does not deform under pressure, and at the same time enhance the turbulence of the liquid and increase the heat exchanger area. There is a hole in the four corners of each plate, and the washer groove is pressed around the plate and hole, and gaskets are placed in the circumferential groove of the hole as needed to allow liquid or prevent liquid from entering the surface. plate face. The role of the interchannel channel. If several plates are arranged in turn on the support according to the heat exchange requirements and the fixed and movable compression plates are compressed by the compression screw, a liquid channel is formed between the adjacent plates, with the help of which help of the four corners of the plate. Drain holes and gaskets.
