Cold Plate Design Tool

ATS Liquid Cold Plate Design Tool

This tool is provided by Advanced Thermal Solutions, Inc. (ATS) to provide a vehicle for engineers to get an estimate of the required design for their application based on finned and tubed cold plates. Its use requires strict company URL and email matching

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.
