文摘

Thermodynamic processes for cryogenic sheet metal forming tools were examined. Static and transient temperature field simulations are evaluated on a Nakajima tool. Differently arranged cooling loops lead to homogeneous temperature distribution. Scaling of the geometry leads to significantly increased heat transfer times. The temperature management of complex forming tools can be developed numerically.
