Designing a new brazed heat exchanger?   Not sure how thick the header plate should be or what cladding % it should have?

Then FillerCalc can help you reach the right answer.

Enter the following in the FillerCalc table:

  • the dimension of the tubes
  • the number of tubes
  • the height of the fins
  • a tentative header thickness
  • a tentative cladding %

FillerCalc will make a prediction of:

  • the average fillet size on each tube
  • the maximum and minimum fillet size on each tube

You can apply different tolerances to the header thickness, cladding % and Si content of the cladding alloy to see what might happen in "worst case" situations.
