Box Header Heat Exchanger Calculation
Engineering Spreadsheet — Instant Download
What This Spreadsheet Does
Sizes box header heat exchangers used in process and HVAC duty — air-cooled exchangers, finned-tube banks, and rectangular header configurations where round headers are impractical.
What’s Inside the Excel File
- Inputs — design pressure, temperature, fluid properties, tube count, tube pitch, header internal dimensions, material allowable stress
- Header plate thickness for pressure containment
- Stay/tie-rod sizing if required
- Pressure drop estimate across the header
- Material weight estimate for procurement
Who This Is For
- Heat exchanger design engineers
- HVAC and process engineers
- Air-cooled exchanger detailers
- EPC project teams on cooling packages
Codes & Standards Referenced
- ASME VIII Division 1 — pressure containment principles
- TEMA — heat exchanger standards (where applicable)
