Sammanfattning
When more and more computing power is needed in todays vechicles, with faster and
more energy consuming computers the cooling of these computers becomes a problem.
Requirements on vibration resistance and protection against moisture leads to
a encapsulation for these computers, which complicates the cooling considerably.
The work has been carried out at Cpac systems AB and has been aimed at simulating
an electronic box that is under development. This is to ensure that heat
transfers becomes sufficient and that no electronic components will be damaged due
to high temperatures.
Several correct simulation models of existing electronics boxes were developed. The
simulation models were verified by performing practical experiments which showed
that the simulation models were in good correspondence with reality.
A new simulation model for the new electronics box was developed with the same
boundary conditions and the values received from previous experiments.
The simulation model of the new electronic box that has been developed can be
used as a basis for decisions regarding:
• Selection of Components
• Component placement
• Enhancement of the box design
Since the new electronic box is not yet produced practical experiments can not be
performed to verify the result from the simulaton. Which becomes a limitation in
this project.
