Regarding the use of copper tubes as heat exchange tubes in the heat exchanger, calculations show a problem of temperature exceeding limits
Thread Content
The heat exchange tubes in the heat exchanger are made of red copper T2. When using SW6 to perform calculations on the tube sheets, those calculations succeed, but when attempting to calculate the external pressure on the heat exchange tubes, the temperature value for the external pressure strain coefficient B curve exceeds the allowable limit. I would like to ask the experts here: how did you solve this problem?
I wonder too, why hasn’t anyone answered?
