In addition, the thickness of the plate is usually in the range of 0.5-1.5. According to the requirements of working conditions, the thickness of the plate is different, and the price is slightly deviated. The different corrugated forms of plate have great influence on heat transfer and flow resistance of plate heat exchanger. According to different working conditions, different corrugated plates are used. Generally, herringbone corrugated plates and horizontal straight corrugated plates are the main ones, and their prices are also different. When the production requirements change the process conditions and output, increasing or decreasing the number of sheets or changing the form of sheet assembly process channel, these operations will affect the price.
