Working Condition Analysis of Active Temperature Control System for Machine Tools Based on Heat Current Model
摘要
In order to analyze the heat transfer performance of the active temperature control (ATC) system for machine tools, heat transfer and flow constraints are constructed and a heat current model of the ATC system pipe network is established on the basis of the entransy-dissipation-based thermal resistance (EDTR). With the aim of minimizing pump power, the model is combined to obtain the pump operating frequency and total flow rate for a given total heat transfer quantity. The working condition optimised parameters obtained from the model are entered into the simulation and analysis of temperature control board (TCB) heat transfer. The simulation results are similar to the trends obtained from the model. The model can provide a theoretical reference for economic working condition analysis of the ATC system and subsequent system pipework design.
