How do heat exchange devices eliminate air blockages?
Thread Content
Our workshop is equipped with five heat exchange units, using ethylene glycol as the cooling medium. Recently, a large amount of gas has been accumulating in the return pipe for the ethylene glycol, and this gas cannot be discharged completely. As a result, gas blockages occur within the heat exchange units, preventing the cooling medium from flowing through them; consequently, the heat exchange efficiency is extremely poor. We would appreciate any advice from the experts. Thank you!

Add a tank such as an ethylene glycol buffer tank or a shunt tank in front of the heat exchanger to serve as a gas-liquid separator. I don’t understand the process; it’s just my personal opinion!
Add a vent valve to the heat exchanger? O(∩_∩)O Haha~ I’ve never seen either how the exhaust valve on a heat exchanger functions to discharge air; it’s just a guess: P
Adding a vent valve is to expel gas from the circulating water system to prevent air lock.
