Design Optimization of Cooling Component through CFD Analysis Case Study Highlights Client Profile: Fuel Cell Stack Manufacturer, China Objective: To optimize the flow uniformity across the cooling component through CFD analysis Challenges: Developing CAD model of the component to = record accurate flow behavior = Applying appropriate boundary conditions to
replicate real conditions
Liquid cooling is one of the most effective methods to cool electronic components, and is being widely adopted in servers, fuel cell systems and desktops. The water circulates around the heat generating electronic devices through pumping arrangement. In liquid cooling, the heat exchanging channels require uniform liquid flow, in order to effectively carry away the heat. A leading fuel cell stack manufacturer from China needed a design solution for the cooling component, in order to equally distribute the liquid across all the channels. The existing design was required to be virtually tested to understand the flow distribution and further modifications in the design was required.
= Identifying regions of optimization in the
component design
The Solution
Solution: Through CFD analysis, the flow uniformity across the component outlet was measured. To optimize the flow distribution at outlet channels, the component design was modified by placing baffles at different sections. The subsequent flow analysis showed beneficial results, maintaining flow uniformity across the outlets.
Hi-Tech’s engineering team developed CAD model of the cooling component to perform CFD simulations and record the flow distribution at the outlet channels. The existing design was first analyzed and non-uniformity in flow was observed. In order to equally distribute the flow across the outlet channels, a design modification was suggested. The existing design was modified by placing baffles at different sections of the component.
Software Used : ANSYS Fluent 14.5 Further simulations were performed on the modified design, and the results showed considerable benefits in flow distribution. The velocity and pressure metrics were well within the permissible range across all the outlet channels. This solution can also be provided using OpenFOAM, STAR CCM+, Abaqus CFD, COMSOL Multiphysics.
Benefits = Improved cooling efficiency of the micro channels by
30% = Reduced cost and time associated with physical testing = Optimized cooling component at the early design phase,
reducing the manufacturing time period
