| Summary: | 碩士 === 國立臺灣科技大學 === 機械工程系 === 104 === Vehicle computer is the industrial computer which is installed in the
car and could turns the car into a digital device and provide information
to assist the driver. With the camera lens and related detectors, it monitors
and provides self-testing for vehicle safety, vehicle-to-vehicle
communication and remote information monitoring..... etc.
This main objective of this dissertation is aimed at optimizing
thermal design of the vehicle computer. Firstly, we will introduce the
overview of the industry and application of the vehicle computer, and
secondly, discussed the differences between vehicle computer and
general computer architecture. The metal chassis of vehicle computer can
be a good cooling method for heat source on the mother-board. Therefore
in the simulation analysis, we defined the material of top chassis (M),
chassis thickness (T), the fin height (H) and front opening ratio (O), and
took three Levels by using the Taguchi method orthogonal table L9 for
thermal simulation analysis, using Minitab to compare the data to find the
best combination of the four parameters. which are the A2 (material is
AL6061), B3 (chassis thickness is 5.5mm), C3 (fin height is 7mm), and
D3 (opening ratio 30%).Ran the analysis software to verify the
temperature of the cooling efficiency verifiable via four control variables
which obtained from Taguchi method and the result proved it was the
best approach for the optimal system thermal design. In this study, by
using Minitab and Flotherm analysis software to find the optimal system
thermal design, the result served as reference for researchers to evaluate
v
and analyze thermal solution, making adjustment according to
experiments and the actual situation, we believe researchers can have
more accurate direction of design. the test results provide such referential
materials for researchers to evaluate and analyze the thermal solution, and
making adjustment based on the experiments and the actual situations
accordingly. We believe that this study can provide researchers with more
accurate idea of design.
