Square Base Heat Sink: Physics Test Q&A

Click For Summary
SUMMARY

The discussion centers on the design of square base heat sinks, specifically addressing their compatibility with chip faces. A square base allows for efficient heat dissipation and is cost-effective due to the manufacturing process, as square sections can be easily extruded from aluminum. The conversation highlights the importance of design choices in thermal management, particularly in relation to physics principles and practical applications.

PREREQUISITES
  • Understanding of heat sink design principles
  • Familiarity with thermal management concepts
  • Knowledge of materials used in heat sinks, specifically aluminum
  • Basic physics related to heat transfer
NEXT STEPS

In my physics test, a question was asked why the heat sink has a square base. Anyone can answer this? i searched the internet but could not find much. Any help would be greatly appreciated. :)
 
Science news on Phys.org
thanks for the reply but i wanted to know about the base, not the fins. But thanks anyway! :)
 
lol But it came from a physics test, so i presume the reasoning should be related to physics but maybe you are right. Thanks anyway! :)
 
Probably because the heat sink is extruded aluminium, and square sections are just cut off from the length. If you wanted a round flat face then extra cost with machining would be involved.
