4. Fluid & Cooling Conditions

Coolant Type

Select the coolant used in the cold plate system.

Other Fluid Properties

For a custom fluid, enter the properties below. These values are included in the backend payload so ATS can retain the fluid in the database for future use.

Design Notes

This demo compares ATS-style finned and tubed cold plate concepts under the same inputs. Final design still needs CAD review, manifold details, test correlation, and manufacturing review.

Disclaimer: These are preliminary calculations for screening and concept development only. Results are based on first-pass engineering correlations, ATS-family comparison logic, constrained packaging logic, and user-entered inputs. They are not approved manufacturing values or final ATS design signoff data.
