How Can I Calculate Wire Temperature Consistently for Electrical Projects?

Click For Summary
SUMMARY

The discussion focuses on calculating wire temperature in electrical projects, particularly when powered by a battery pack. The user seeks to design battery requirements and wire size to maintain a specific temperature. It is established that heat dissipation must be calculated using heat transfer principles to determine a relatively constant temperature in the wire. The consensus is that while theoretical calculations are challenging, practical measurement may yield more accurate results.

PREREQUISITES
  • Basic understanding of electrical engineering principles
  • Familiarity with heat transfer calculations
  • Knowledge of wire gauge specifications
  • Experience with battery pack design
NEXT STEPS
  • Research heat transfer calculations for electrical components
  • Learn about wire gauge temperature ratings and their implications
  • Explore methods for measuring wire temperature in real-time
  • Investigate battery pack design considerations for thermal management
USEFUL FOR

Electrical engineers, hobbyists designing battery-powered projects, and anyone involved in thermal management of electrical components will benefit from this discussion.

I am looking to determine the temperature in a certain gauge wire, fed by a battery pack. I am looking to design the battery requirements and wire size in order to maintain a certain temperature. The electrical calculations (I am not an electrical engineer) I have found all assume continually increasing temperatures. Am I right in assuming that I would need to calculate the heat dissipation using heat transfer calcs in order to determine the relatively constant temperature that would be obtained based on my parameters? Or is there a straight forward calc that can be used to estimate (I do not need exact temps) the temps that would be maintained in the wire? All help is greatly appreciated.

If you continually put heat into something but it can't escape, the temperature will keep rising.

So, yes, you do need to consider the cooling as well as the heating.

Unfortunately, this is probably more difficult to estimate than to actually build it up and measure it.
