Analysis of the reason why the exhaust temperature does not decrease after cleaning the cooling water fouling in an air compressor

This morning, after testing the compressor, I found that the exhaust temperature was 94 degrees before cleaning, and it remained at 94 degrees even after cleaning – it didn’t drop at all, which is unusual. I can’t identify the cause, and now I don’t know what to do. Please help analyze the reason; thank you!
There is a significant temperature difference between the inlet and outlet of the circulating water. After removing the end caps of the oil-cooling section, it was observed that the circulating water flows through the tube side; from the openings in the caps, it could be seen that the cleaning effect was good – everything was thoroughly cleaned. The cooler is made of copper, and its natural color could be seen clearly
Check the thermometer to see if there is a low pressure difference between the inlet and outlet of the circulating water, resulting in slow water circulation.
I have 8 air compressors running in parallel; this scenario is unlikely····· Moreover, there’s one compressor that hasn’t been cleaned since it was put into use, and its temperature is still at 78. Even after it has been cleaned now, the temperature doesn’t drop – it’s really strange
Is it possible to directly measure the wall temperature of the tube using a thermometer on site? No change before or after cleaning? I don’t understand… Who can give a reasonable explanation?
Haha, new copper surfaces can be seen at both ends of the end cap, but how long is the tube side of your cooler? Is new copper surface visible there as well?
Using a hose with a diameter similar to that of the copper tube makes it quite easy to push through; it should be fine
After cleaning, it’s possible that some of the pipes are blocked. Check it out
The water side has been cleaned; the air side also needs to be cleaned, especially those with fins.
I really can’t think of anything on the air side that could be cleaned Air flows through the tube side; it shouldn’t get clogged, right?
This problem is really strange. We called the manufacturer’s technicians, had the equipment serviced thoroughly, replaced everything that needed to be replaced, but the issue still persisted. It’s really hard to figure out where the problem lies
