What is a plate heat exchanger?
Plate heat exchanger is an efficient heat exchanger composed of a series of metal sheets with certain corrugated shapes stacked together. Thin rectangular channels are formed between various plates for heat exchange. Plate heat exchangers are ideal equipment for heat exchange between liquid and liquid, as well as between liquid and vapor.
Characteristics of Plate Heat Exchanger
►Plate heat exchangers have high heat transfer efficiency
The heat transfer coefficient K of plate heat exchangers is within the range of 3000-6000W/m2.oC.
►Plate heat exchanger adapts to changing circumstances
The heat exchange plate is easy to disassemble, and by adjusting the number of heat exchange plates or changing the process, suitable heat transfer effect and capacity can be obtained.
►Plate heat exchanger has low heat loss
Due to its compact structure and small size, the outer surface area of the heat exchanger is also very small, resulting in minimal heat loss. Typically, the equipment does not require insulation.
►Reliable use of plate heat exchangers
Two seals are designed on the sealing device between the plates, and signal holes are also provided. Once leakage occurs, it can be discharged outside the heat exchanger, which not only prevents the mixing of the two media but also serves as a safety alarm.
►Plate heat exchangers are beneficial for the utilization of low-temperature heat sources
Due to the almost completely counter current flow and high heat transfer efficiency of the two media, it is an ideal equipment for recovering low-temperature waste heat or utilizing low-temperature heat sources.
►Plate heat exchangers have a small footprint and are easy to maintain
The structure of plate heat exchangers is extremely compact, occupying only 1/2 to 1/3 of the space of shell and tube heat exchangers under equal heat conditions.
►Plate heat exchanger has less resistance loss
On the premise of the same heat transfer, compared with the shell and tube heat exchanger, the plate heat exchanger has reduced the equipment investment, infrastructure investment, power consumption and other costs due to the reduction of heat exchange area, floor area, fluid resistance, cooling water consumption and other project values. Especially when expensive materials are needed, the equipment is more economical due to the efficiency and thin plates.
