Nozzle-field cooling is a popular cooling technology which uses a flexible array of low-pressure gas jets to quickly cool down components in a device working in conventional atmosphere. This cooling process is energy saving, free of toxic gases, and it can reduce workpiece distortion during cooling. In this study, nozzle-field cooling is adopted for a potential, fast cooling process for large metal blanks. Numerical simulations were conducted to investigate the performance of a designed cooling tool with different design parameters. In this paper, simulation results are presented, along with several considerations for the nozzle-field cooling system design.
- air cooling
- hot stamping
- coupled CFD-thermal simulation
- aluminium alloys
- parametric simulation
