Principle
A plate heat exchanger is a high efficiency heat exchanger that is assembled from a series of metal sheets with a certain corrugated shape. A thin rectangular channel is formed between the various sheets, and heat is exchanged through the sheets. Plate heat exchangers are the ideal equipment for heat exchange between liquid-liquid and liquid-vapor.It has the advantages of high heat exchange efficiency, small heat loss, compact and light structure, small occupied area, wide application and long service life. In the case of the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, but the floor space is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more.

Characteristics of plate heat exchanger
High heat transfer coefficient: the design of the plate corrugation is aimed at the high thermal conductivity. The special flow path are formed by the plate corrugation causing strong disturbance flow at a very low flow rate, which is called turbulent flow. And the disturbance flow can be self-cleaning to prevent fouling and thus the heat transfer efficiency is high. Generally speaking, the heat transfer coefficient K value of the plate heat exchanger is in the range of 3000-8000 W/m 2?. This shows 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 logarithmic temperature difference
the temperature difference at the end is small, and the plate heat exchanger is mostly a cocurrent or countercurrent type of flow. In addition, the flow of the cold and hot fluid in the plate heat exchanger is parallel to the heat exchange surface and has no bypass flow which making the temperature difference at the end of the plate heat exchanger is small.
-
-
Small footprint and easy maintenance
The plate heat exchanger has a compact structure, and the heat exchange area per unit volume is 2-5 times that of the shell-and-tube type, and it's not like the like the shell and tube type that needs place for inspection and repairing. Therefore, the floor area of the plate heat exchanger is about 1/2-1/3 of the shell and tube heat exchanger when achieving same heat exchange capacity .
-
-
Easy to change heat transfer area or process combination
as long as several plates are added or reduced, the purpose of increasing or decreasing the heat exchange area can be achieved; changing the plate arrangement or replacing several plates can achieve the required path combination to adapt to the new heat exchange conditions, at the same time,the area of the shell-and-tube heat exchanger is almost impossible to increase.
-
-
Low investment
With the same heat exchange capacity, when compared with the shell and tube heat exchanger,because of the decrease of heat exchange area, floor space, fluid resistance, cooling water consumption etc, plate heat exchanger has much lower expense on equipment investment, base investment, power consumption etc.
-
-
Safe and reliable use
double seal are designed on the sealing device of the plate, and there is a signal slot. Once the leakage occurs, it can be discharged outside the heat exchanger, which prevents the two media from mixing,and at the same time it can be a security alarm.
-
-
Easy to clean
As long as the plate heat exchanger loosens the compression bolt, the plate pack can be loosened and the plate can be removed for mechanical cleaning, which is very convenient for the heat exchange needs to be cleaned frequently.
-
-
Small heat loss
Only the outer plat exposes to the atmosphere, so the heat loss is negligible and no heat preservation measures are required. The shell and tube heat exchanger has a large heat loss and requires a heat insulating layer.
-
-
It is not easy to scale
due to the sufficient flow of internal medium, impurities are not easy to deposit, so it is not easy to scale, the dead flow area of the passage between the plates is small, the heat exchange surface made of stainless steel is smooth, the deposit is small, and the cleaning is easy.
-
-
Small resistance loss
The resistance loss is small. Under the condition of same heat transfer coefficient, the plate heat exchanger can choose the flow rate reasonably, and the resistance loss can be controlled within 1/3 of the shell and tube heat exchanger.
-
-
Small amount of cooling water
The amount of cooling water is small, the plate heat exchanger is caused by the geometry of the flow channel, and the two liquids have very high thermal efficiency, so the amount of cooling water can be greatly reduced, which in turn reduces pipes, valves, And pump installation costs.
