CHARACTERISTICS

High heat transfer coefficient

01 High heat transfer coefficient

The corrugated shape of the sheet is designed for high thermal conductivity of the film, which forms thin rectangular channels that allow the fluid to flow at low velocities. Strong turbulence can also occur. Turbulence has a self-cleaning effect to prevent the formation of fouling, resulting in a high heat transfer efficiency. In general, the heat transfer coefficient of plate heat exchanger K value in the range of 3000-8000W/m2 ℃. This indicates that the plate heat exchanger only needs 1/2-1/4 of the shell and tube heat exchanger area to achieve the same heat transfer effect.

Large average logarithmic temperature difference

02 Large log-averaged temperature difference

Plate heat exchanger is mostly parallel or counter-flow flow. Select the process and the number of channels, the initial selection of cold and hot fluid flow and the number of channels, and the resulting calculation of the flow rate. Cold, hot fluid in the plate heat exchanger flow in parallel to the heat transfer surface, no bypass, thus making the end temperature difference is small, logarithmic average temperature difference is large .

Compact structure with small cooling capacity and low investment.

03 Compact structure, small cooling water volume, low investment

Plate heat exchanger is an efficient and compact heat transfer equipment, the heat transfer area per unit volume is 2-5 times that of shell and tube. Small footprint, easy to maintain and clean, to achieve the same heat transfer, plate heat exchanger covers an area of about 1 / 5 of the shell and tube heat exchanger ~The geometric shape of the flow channel makes the liquid heat exchange efficient, reduces the water consumption for cooling, and is economical.

Easy to expand, change the heat transfer area or process combination

04 Easy to expand, change the heat transfer area or process combination

An increase or decrease in heat transfer area can be achieved by simply adding or subtracting a few plates; changing the plate arrangement or replacing a few plates. It can achieve the required combination of processes to adapt to the new heat transfer conditions, while the shell and tube heat exchanger heat transfer area is almost impossible to increase.

Not easy to scale, easy to clean, safe and reliable

05 Not easy to build up scale, easy to clean, safe and reliable

Smooth heat exchange surface, large turbulence, full flow of internal medium, impurities are not easy to deposit and scale, small dead flow area of inter-plate channel; only frame The plate heat exchanger can be loosened by loosening the clamping bolts, and the plate can be removed for mechanical cleaning, which is important for frequent cleaning of the equipment. The heat transfer process is very convenient. The plate seal is designed with two seals and a signal slot to allow it to be discharged outside the heat exchanger in the event of a leak. It prevents the two media from mixing and also acts as a safety alarm.

Low heat loss, and resistance loss

06 heat loss, and low drag loss

Only the shell of the heat transfer plate is exposed to the atmosphere, the heat loss is negligible, and no insulation measures are required. The shell and tube heat exchanger has large heat loss and needs thermal insulation layer; under the same heat transfer coefficient conditions, through a reasonable multi-process combination arrangement, the more The flow combination exhibits a mixed flow pattern with a slightly lower average heat transfer temperature difference. Resistance loss can be controlled in the range of 1/3 of the shell and tube heat exchanger.
