Tips on Welded Plate Heat Exchangers

The advantages and uses of different types of plate heat exchangers are different. So, do you know what are the advantages of welded plate heat exchangers? And, what are the daily maintenance precautions for heat exchangers? Here is a brief introduction to the relevant content.

Here is the content list:

• Excellent performance

• Good overall rating

• Daily maintenance precautions

Excellent performance

Welded plate heat exchangers in the structure of the choice of materials are weldable or stamping materials, in terms of structure can be diversified in design and can be used with a variety of temperatures and space. The welded plate heat exchanger can change the fluid flow state by adjusting the spacing and shape of the plates, and when the Reynolds number is in the hundreds, it can make the medium turbulent, which increases the heat transfer efficiency. Welded plate heat exchanger produces a fouling coefficient one-fifth of that of the tubular heat exchanger.

Good overall rating

Because the corrugated plate is welded around, the inner side of the plate expands and contracts during operation depending on the heat capacity, so fouling does not occur easily. Also because of the structure of the plates, it is possible to make all plates participate in heat exchange and maximize the effect of plate heat exchange, realizing a dead-end condition. Higher heat transfer efficiency can be obtained at a lower resistance, especially when heating fluids or cooling. This effect also reduces the amount of kinetic energy consumed, further reducing costs. The welded plate heat exchanger can also be expanded to allow for freedom of expansion and contraction to suit the space environment. Due to the compact structure, the heat transfer area density of the welded plate heat exchanger is 250 m, while the footprint is one-sixth of that of the shell and tube heat exchanger, which reduces the capital investment cost to a certain extent.

Daily maintenance precautions

Check the overall appearance of the fully welded heat exchanger and whether the plates are deformed. Check whether the heat exchanger plates are over-frosted. If there is too much frost, increase the hot water temperature or adopt the intermittent working mode. Check whether there is any cracking and leakage in the welded pipe system of the heat exchanger and gasifier. Check whether each group switching (automatic) device is normal. Check whether the safety accessories related to the heat exchanger are normal and intact. Check whether the foundation of the heat exchanger equipment is solid.

These are the advantages of welded plate heat exchangers and the daily maintenance precautions related to the above, I hope it will help you. Routine maintenance of the heat exchanger can extend the service life of the heat exchanger.
