Following this trend, the topic of Quality Management becomes more and more important. Therefore, the existing problem of long examination process, which causes worse manufacturing efficiency and higher cost, turns to be one issue to be further improved in cooling field.ur research focus on designing the experiment methodology and process for heat pipe cooling module, and try to analyze the temperature response change of each component in heat pipe cooling module under different situations. The main experimental parameters include the heating methods, heating temperature, and time to turn on the fan. In addition, based on Lumped System theory, we build up a simulation model to find out the dynamic temperature response of heat pipe cooling module, and then set up experimental parameters. Under this simulation, we could reduce the time and cost on testing parameters and analysis principles with try and error method.he study proves to be the successful simulation model to find out suitable parameters range and analysis principles under different heating methods. Finally, our research results successfully shorten the examination time to 30 seconds through transient examination method. |
