High heat transfer efficiency
The heat transfer coefficient K of the plate heat exchanger is in the range of 3000-6000 W/m2.oC.
Hesitant heat exchanger plates are easy to disassemble, and the most suitable heat transfer effect and capacity can be obtained by adjusting the number of heat exchanger plates or more.
Small heat loss
Due to its compact size and small size, the outer surface area of the heat exchanger is also small, so the heat loss is also small, and the equipment is usually no longer required to be insulated.
Safe and reliable to use
Two seals are designed on the sealing device between the plates, and at the same time, there are signal holes. Once the leakage occurs, it can be discharged to the outside of the heat exchanger, which prevents the two kinds of media from mixing and plays a role of safety alarm. .
Conducive to the use of low temperature heat sources
Since the two media are almost full countercurrent flow and high heat transfer effect, the minimum temperature difference between the two media of the plate heat exchanger can reach 1 degree. It is ideal for recycling low temperature waste heat or using low temperature heat sources.
Small footprint and easy maintenance
The plate heat exchanger has an extremely compact structure, and the space occupied by the plate heat exchanger is only 1/2 to 1/3 of that of the shell-and-tube heat exchanger.
Less resistance loss
Under the premise of the same amount of heat transfer, compared with the shell-and-tube heat exchanger, the plate heat exchanger has reduced the values of heat exchange area, floor space, fluid resistance, cooling water consumption, etc., resulting in equipment investment, infrastructure investment, Costs such as power consumption are greatly reduced, especially when expensive materials are required, and equipment is more economical due to efficiency and thin sheets.
