SUMMARY

The discussion focuses on modeling the thermal dynamics of two closely spaced heat sources, specifically electrical cables carrying current, and their interaction with a heatsink located 1.3 meters away. The primary challenge is determining the temperature at which to calculate the heat transfer (Q) due to the influence of both cables on the surrounding environment. The model is established in a steady state, with prior experience in single cable modeling serving as a foundation for this more complex scenario.

PREREQUISITES
  • Understanding of thermodynamic principles, particularly heat transfer.
  • Familiarity with steady state modeling techniques.
  • Knowledge of electrical resistance and its impact on heat generation.
  • Experience with thermal simulation software for modeling heat distribution.
NEXT STEPS
  • Research methods for calculating heat transfer in multiple heat sources.
  • Learn about thermal conductivity and its role in heat dissipation.
  • Explore steady state analysis techniques for complex thermal systems.
  • Investigate simulation tools like ANSYS or COMSOL for thermal modeling.
USEFUL FOR

Engineers, thermal analysts, and researchers involved in thermal management and heat transfer modeling, particularly those working with electrical systems and heatsink design.

I am going to create a model, with two heatsources closely spaced (Cables with a current) Covered with dirt and at a distance 1.3m from each cable there are a heatsink surround them.

My problem is when I am going to create the model, I am not sure at what temperature i need to calculate the heat Q, because the temperature between the cables must change because of the two cables, and that would effect the heat Q.

The goal is to know the temperatures at a distance R, from one cable and Q from both cables.

The model with to cables is steady state

And i have create a steady state model for 1 cable, but not with to closely spaced
