Abstract: Brief introductions to the application and the packaging process of miniaturized multi-channel heat exchanger are presented. And the overview on the simulation and modeling of the brazing packaging for the multi-channel heat exchanger (MCHEX) are the focus of this article. Four levels of brazing packaging simulation for MCHEX (specially for the compact plate-fin heat exchanger) are listed, respectively, which include that the thermodynamic simulation for the overall MCHEX structure, the modeling of typical multi-channel structure, the numerical analysis for the brazed joint and the analytical modeling of brazing mechanism based on diffusion. The research difficulty and some important issues needed to solve are also pointed.
