Helical Coil Heat Exchanger Design

Helical coil heat exchanger design (HCHex) software is made to demonstrate the thermal design calculations for helical coil heat exchanges.
The software will do all the sizing and thermal calculations involved in the design and will generate a summary of all results. Below are some features for this software along with any limitations.

Helical Coil Heat Exchanger Software Features

Virus free software

+ Design helical coil heat exchangers, two models are supported.
Model 1 with core tube design, Model 2 without core tube design.
+ Support S.I Units and English (U.S) Units of measurement.
+ Units converter includes 23 measurements units with 200-unit conversion
+ Add your own Nusselt correlation
+ Save/Load results


+ Ability to calculate unknown Cold or Hot side temperatures. Unknown exit temperatures on both sides or any two temperatures on both sides
+ Unknown Flow rate on either hot or cold side, calculate both flow rates also if heat duty and temperatures are specified.
+ Pressure Drops for both shell and tube sides (frictional, inlet, outlet and total)
+ Overall heat transfer coefficients, heat transfer coefficients for shell and tube sides.
+ Nusselt number estimation
Helical coil heat exchanger design software includes Nusselt number correlations and will also allow you to use your own correlations in three formats,
The software will also allow you to enter your own Nusselt number or enter a heat transfer coefficient if needed.
+ Area and heat load (heat duty) calculations
+ Vessel dimensions, length, height and diameter and other values
+ Number of spiral turns for the helical tube and its length.

The software will also accepts heat duty or heat load as input and calculate other needed variables

Included databases

+ Estimate the Physical properties of pure components for more than 1450 fluids; the database has the ability to estimate Thermal Conductivity, Density, Heat Capacity and Viscosity. The database also included critical properties, boiling and melting points and come as a standalone interface but easily integrated with the software.
+ User database functions to allow user to add/delete fluids, Tube geometric sizes and heat transfer coefficients and load to hot/cold side (Empty database!).
+ Fouling factors
+ Add your own Nusselt number correlations, three formats are available.


Plot temperature profile for counter current flow and co-current flow. detect temperature cross.


+ Export Results summary to Microsoft Excel Engineering Datasheet format. Save/Load results. Generate/Print a summary of results
+ Display multiple cases in results grid
+ Export Results summary to .rtf file format that can be opened in Microsoft Word


+ Single tube units, multi tubes are not supported.
