Abstract

Intelligent manufacturing processes are increasingly using vapor chambers(VCs). VCs has a high heat transfer rate. Numerical simulation is used to explore the structural design for shortening the length of the condenser and improving the performance of the VCs. The condenser of VCs at this stage is long and not suitable for smart manufacturing design. Reveal the phase transition inside the VCs by COMSOL-2D. Optimization of the structural design to shorten the length of condenser. Hollow fin structure VCs in condenser section shortens the condenser section and improves the heat exchange efficiency. The results show that: (1) The heat dissipation performance of the VCs has been improved, while the length of the condenser has been reduced to 30% of the overall length. (2) After the orthogonal experiment simulation, the importance of the influence of each factor on the heat dissipation capacity of VCs was as follows: number of hollow number of fins is more important than fin length, fin length is more important than fin width, fin width is more important than the horizontal angle of the fin. Special-shaped VCs structure has certain engineering design value and provides new ideas for the heat dissipation method of high-power intelligent devices.
