To promote the flow of liquid between the plates forming turbulence. The metal plate can vary with different pressures. "Herringbone" Komon plate flow channel is composed of two miter angle difference between the adjacent plates composed of 180 degrees. Therefore, between plates attached corner lot, it can reach 2 per 130mm. Runner easily deformed, high pressure, can withstand strong pressure. And because the flow is three-dimensional, more intense turbulence, and therefore high heat transfer coefficient.
Plate heat exchanger works
The company sells plate heat exchangers are used in "herringbone" ripple.
Sheet material: SUS304,316L, 321, titanium, titanium alloy or according to user requirements.
Thickness (mm): 0.5 ~ 1.0
Gasket Material: NBR, EPDM, Viton or according to user requirements.
Plate heat exchanger is the space occupied by a variety of heat exchangers in a small, under the same conditions for the plate heat exchanger heat transfer area is just a shell and tube heat exchanger 1/3 ~ 1 / 4, and without taking up extra space for maintenance when removing.
Since the plate pack flowing medium low Reynolds number (Re), the turbulence can be formed, but not easy to generate smooth dirt on the plate, and therefore has a very high heat transfer efficiency, in general, water and a water heat exchange , plate heat exchanger heat transfer coefficient can reach 6000w / m over 2 ℃, shell and tube heat exchanger 3-8 times higher.
High heat recovery:
Since the heat transfer coefficient, excellent flow properties combined with completely reverse flow ratio, temperature difference can be selected very end, so it is suitable for low-energy heat recovery, the use of a single plate heat exchanger more than 90% of the heat recovery economically feasible.
Folding plate heat appliance Have theory than adaptability. After installation, the metal plate pack can be increased or decreased to adapt to widen narrow process requirements.
Low flow stagnation:
Because of the flow channel is small, stagnant flow is very small, it can start fast, responsive control operation is changed, and greatly reducing the weight of the equipment.
Plate is designed to be no dead area so you can without disassembly in the field of chemical cleaning, for plate heat exchanger can also be easily opened for a thorough mechanical cleaning.
