ABSTRACT
cooling channel design and its fabrication processes are limited to respectively simple configurations as well as conventional machining processes, such as straight-line drilling, and milling, etc.
In this research, the cooling process of thermoplastic injection moulding is first reviewed from the heat transfer viewpoint. The most effective heat transfer that can be achieved in practice is then formulated in terms of visibility concepts of computational geometry. Feasibility checks for both conventional straight-line drilled cooling channels and conformal ones are then analyzed with light illumination.In addition, variable radius conformal cooling channel (VRCCC,) conformal porous pocket cooling (CPPC,) and conformal pocket cooling (CPC) are proposed to test their heat transferrabilities, and benchmarked against the straight-line drilled cooling channel.
