Thermal Simulation of a Heat Pipe Tempered Injection Mould Tool

The Bielefeld University of Applied Sciences [FH Bielefeld] developed an injection-moulding tool which is tempered by using heat pipes instead of common water based cooling channels. The performance of each heat pipe is precisely determined and displayed as a function. By using the individual heat transfer function of the heat pipe, these can be represented within a COMSOL based heat transfer simulation. The COMSOL model has been validated by comparing real experiments and the simulation results which only show slight differences in the temperature distributions inside the injection-mould.
