The differences between tube and shell heat exchanger and gasket plate heat exchanger

2023-10-27

Many times, for new contacts in the heat exchanger industry or customers, there is no understanding of the difference between tube heat exchangers and plate heat exchangers, and their respective performance is not clear. Today, Baode will simply introduce the main differences between the tube and shell heat exchanger and gasket plate heat exchanger:

Gasket Plate Heat Exchanger

1. Structure and form
As the name suggests, the main shape of the tube is the shape of the tube, and the internal heat exchange parts are also composed of a certain number of small round tubes; The shape of the plate heat exchanger plates is mainly rectangular, and the internal heat exchange parts are composed of a certain number of stainless steel plates.

2. Heat transfer efficiency
Both tube type and plate type belong to inter-wall heat transfer. By separating the cold and hot media, each in its own channel in contact with each other, resulting in the principle of heat transfer. Since the wall thickness of the tube is generally between 0.8-1.2mm, and the plate thickness of the plate heat exchanger is between 0.4-0.5mm, under the same parameters, the heat transfer performance of the plate is 3-5 times that of the tube.

3. Interface form
In general, the four mouths of the tube are separated. Usually, one is left and right, and one is upper and lower. The conventional interface of the plate heat exchanger is on the same side. According to the combination of the process, it can also be made into a front and back, diagonal or segmented interface form.

4. Construction cost

Because the tube is a closed form, once there is a blockage or leakage, it needs a lot of time and manpower to clean or replace. Plate heat exchanger through the principle of detachable, two people can be the heat exchanger for a whole machine cleaning or area increase, greatly improving the work efficiency. So in the long run, the cost performance of the plate is much higher than that of the tube.

Gasket Plate Heat Exchanger is a new and efficient heat exchange equipment, which has been widely used in many industries such as power engineering, shipbuilding, metallurgy, petroleum, chemical industry, food and light industry. Brazed Plate Heat Exchanger is designed for a wide range of applications, including HVAC, refrigeration, industrial processes, and renewable energy systems.
