Stainless steel Brazed plate heat exchanger Introduction

Since the heat transfer surface of the stainless steel plate heat exchanger can press the concave-convex liquid discharge groove, the turbulent flow state can be generated under the condition of lower Reynolds number, so the heat transfer coefficient is high, generally up to 3 000-5 000Kcal / m2. h. ° C, compared with the shell-and-tube heat exchanger at the same flow rate, this value is about 3 to 5 times the heat transfer coefficient of the shell-and-tube heat exchanger, although, at this time, the plate heat exchanger The resistance will be larger, as compared to the case of the same power consumption, the heat release coefficient of the stainless steel plate heat exchanger is about twice as high as that of the shell type.


Feature:

Due to the compact structure and small gap of the stainless steel welded plate heat exchanger, the heat transfer area per unit volume is increased, and the installation area is about 1/2 to 1/3 of the shell-and-tube type, which can save floor space and construction cost. When the volume of each shell is 1 m3, the heat transfer area is about 80 m2. In addition, the plate heat exchanger is easy to increase or decrease the heat exchange area. For the shell-and-tube heat exchanger, when the liquid processing capacity needs to be increased, the original heat The heat transfer area of the exchanger is almost impossible to increase, but the heat transfer area of the stainless steel plate heat exchanger is easily increased, thereby increasing the processing capacity.

In addition, the stainless steel plate heat exchanger only exposes the outer plate of the heat transfer plate to the atmosphere, so the heat loss is negligible and no insulation measures are required. One of the characteristics of the plate heat exchanger in terms of operation and maintenance is that it is convenient to assemble and disassemble, and it is not necessary to completely disassemble it. Only the loosening bolt can be loosened to remove the plate to clean, replace the gasket, and even replace the plate. This is especially important for materials that are prone to deposits in the heat exchange medium. Allowable temperature and pressure: For the plate heat exchanger, the gasket between each two plates is used to prevent material leakage, so the total length of its sealing perimeter is very long. Preventing gasket leakage is an important factor in plate heat exchangers. In the link, the gasket can withstand.
