The plate heat exchanger is a heat exchange device with a compact structure and easy assembly and disassembly, so it is more convenient to clean and repair.


The plate exchanger is composed of various parts. There are several important parts in the plate exchanger and what role they play in the heat exchanger. I believe that understanding these can provide you with some help in the maintenance work:

1. Front pillar


Support the weight of the heat exchanger, so that the entire plate heat exchanger is integrated.


2. Movable compression plate


It can be used in combination with the fixed pressure plate, which can be slid on the upper guide rod for easy disassembly, inspection and maintenance.


3. Up and down guide rod


Bear the weight of the plates and ensure that the plates slide during installation. The guide rod is usually longer than the heat exchange plate group to loosen the compression bolts and slide the plates for inspection.


4. Sealing gasket


Prevent fluid mixing or leakage, and distribute it among different plates. The materials are: nitrile rubber, EPDM, fluorine rubber, etc. Different rubbers are used according to different media.

5. Heat exchange plates


Provide medium flow channel and heat exchange area. Generally, the corrugation is made into a herringbone shape. According to the different fluid medium, the material of the heat exchange plates of the plate heat exchanger is different, and most of them are made of stainless steel and titanium.


6. Fix the pressure plate


Do not contact with fluid, tighten the gasket with clamping bolts to ensure sealing.


7. Tighten bolts and nuts


Press the plate group to integrate the heat exchanger and ensure the sealing.


This concludes the description of the important components and functions of the plate heat exchanger, and any of the above components play a vital role in the heat exchanger. In the process of maintaining and overhauling the heat exchanger, if any part is found to be damaged, it should be replaced in time, otherwise it will seriously affect the normal use of the heat exchanger.
