Heat Exchanger Yield at 99% target heat exchanger yield: a worked example

This scenario runs the heat exchanger yield calculation on the strong side: 99% target heat exchanger yield, with every other input held at its documented default. Use it when a quality manager or manufacturing engineer is tracking exchanger performance by line, supplier, braze cell, or test station.

The inputs for this scenario

  • Accepted heat exchangers: 186 exchangers (unchanged)
  • Total heat exchangers tested: 200 exchangers (unchanged)
  • Target heat exchanger yield: 99 % (raised for this scenario; the documented default is 96)

Working through the calculation

  • Applying the documented formula (Heat exchanger first-pass yield = accepted heat exchangers ÷ total heat exchangers tested × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 93 % for heat exchanger first-pass yield, the number this scenario is built around.
  • At this operating point the engine returns 6 points for heat exchanger yield gap to target.
  • At this operating point the engine returns 186 count for accepted heat exchangers.
  • At this operating point the engine returns 200 count for total heat exchangers tested.

How this compares with the baseline

  • Against the tool's baseline example, where target heat exchanger yield sits at 96% and the headline result is 93 %, this scenario lands almost exactly on the baseline at 93 %.
  • Use it for daily or per-batch quality tracking on a heat exchanger test line, or to qualify a braze process change. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Heat exchanger first-pass yield: 93 % (headline result)
  • Heat exchanger yield gap to target: 6 points
  • Accepted heat exchangers: 186 count
  • Total heat exchangers tested: 200 count
