Talking about the domestic cost-effective plate heat exchanger_
There are many brands of 3200 plate heat exchangers. There are many well-known imported brands, and some domestic plate heat exchanger brands with high cost performance. Today I will introduce the plate heat exchanger of Diguang brand. The heat exchanger is a high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, long service life and so on. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, the floor area is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more. There are mainly two types of plate heat exchangers: frame type (removable) and brazed type. The plate forms mainly include three types of herringbone corrugated plates, horizontal straight corrugated plates and knob-shaped plates. The detachable plate heat exchanger is made of many stamped corrugated thin plates at a certain interval, sealed by gaskets around them, and laminated and compressed by a frame and a compression screw. The four corner holes of the plates and gaskets form a fluid divider. The piping and the collection pipe, while reasonably separating the cold and hot fluids, make them flow in the flow channels on both sides of each plate, and heat exchange through the plates.
