KoolDesigns^TM Analytical Thermal Modeling Speeds Cold Chain Solutions to Market

Cold Chain Technologies (CCT) is pleased to offer its customers KoolDesigns, the most efficient, accurate predictive thermal modeling service available in the cold chain market. KoolDesigns, which was developed by CCT in collaboration with Maya Heat Transfer Technologies, LTD., accomplishes the complex task of advanced predictive thermal modeling by accurately and expeditiously accounting for conduction, convection, phase change, and radiation.

Conduction is properly modeled routinely by applying many standard finite element methods. However, properly and accurately simulating phase change and convection are much more complex problems requiring advanced analytical techniques.

Phase Change - Proper simulation of phase change is critical to accurately modeling thermal packaging design. KoolDesigns models the non-linear thermal behavior of all phase change materials (dry ice, water based, hydrated salts, or organic oils and fats). Unlike methods based on temperature varying specific heat, KoolDesigns incorporates an enthalpy-based formulation for computing the energy balance in control volumes that are changing phase. This approach yields accurate results even for very large time steps and temperature changes.

Convection - KoolDesigns uniquely quantifies the overall effect of convection, in contrast to other (incomplete) thermal models that only account for conduction. Convection, which plays an important role in robust thermal packaging design, is quantified by employing KoolDesigns coupled "Finite Difference Control Volume (FDCV)/Computational Fluid Dynamics (CFD)" method.

Modeling/Solution Efficiency - KoolDesigns allows both modeling and solution efficiency through use of its concise/efficient meshing techniques and its coupled thermal/flow solver. Specifically long transient profiles (5 days or more) can be simulated within a reasonable solve time (e.g., 4 to 12 hours).

APPLICATIONS

New Product Development

CCT's design engineers are successfully utilizing KoolDesigns to facilitate quick and accurate design optimization to evaluate multiple design concepts and contemplated revisions, and to increased speed to market by reducing the need for iterative physical testing.

Advanced Applications

Evaluation of Existing Designs with Alternate Ambient Temperature Profiles

KoolDesigns allows quick evaluation of how an existing package design that was qualified against a specific ambient temperature profile will perform against alternative profiles, including profiles generated by updated ambient mapping studies and profiles representing new shipping lanes.

Evaluation of Existing Designs for New Payload Families

KoolDesigns can help to bracket product payload attributes in order to set defined limits within which any variety of payload configurations can be deemed as allowable for that shipper design.

Evaluation of Out-of-the-Ordinary Shipment Conditions

When unanticipated shipping conditions occur that result in extreme temperatures and/or extended exposure durations, KoolDesigns provides a useful tool to predict the impact on the temperature sensitive product payload. This can be very valuable in assessing whether or not product stability has been compromised.

A Valuable Tool - KoolDesigns

KoolDesigns analytical thermal modeling is extremely valuable in our internal new product development work as well as in working with client companies when evaluating and designing different solution scenarios within their distribution environments. It is another tool employed at CCT aimed at producing better solutions, faster, and in a more economical fashion.
