Battery Powered Nichrome Heating Element (80 Degrees)

Click For Summary
SUMMARY

This discussion focuses on the use of nichrome wire as a battery-powered heating element capable of reaching temperatures between 80 to 100 degrees Fahrenheit. Participants highlight the suitability of nichrome for high-temperature applications but express concerns about the lifespan of nichrome coils under repeated heating and cooling cycles. The conversation also touches on the need for a compact design, specifically a heating element no larger than 1/4 inch in diameter, that can be immersed in propylene glycol. The voltage range discussed is between 3.7V and 7.4V.

PREREQUISITES
  • Understanding of nichrome wire properties and applications
  • Basic knowledge of battery power systems and voltage requirements
  • Familiarity with thermal management concepts
  • Experience with heating element design and safety considerations
NEXT STEPS
  • Research nichrome wire specifications for optimal heating applications
  • Explore battery technologies suitable for heating elements, focusing on 3.7V to 7.4V options
  • Investigate thermal insulation materials to enhance heating efficiency
  • Learn about closed-loop control systems for precise temperature regulation
USEFUL FOR

This discussion is beneficial for engineers, hobbyists, and researchers involved in thermal management, heating element design, and battery-powered device development.

Hi there,

I have been doing research on a lil private project of my own, and am looking for some help.

Would it make sense to use nichrome wire to build a heating element that will heat to 80-100 degrees? It seems that nichrome is great for heating way way past that temperature. I want to run this initial test off of battery power.

Thanks in advance for any insights!

More information needed? Fahrenheit?,Open loop control?, closed loop? How about the wrap for pipes that helps keep them from freezing, open loop-constant temp, would that work?

Hi there,

I'm looking to heat a 4in X 4in pad to 80 degrees F. Sorry I am a real newbie in this area, and trying to prototype a battery powered heating element.

I'm trying to apply this at a very small scale to not cause any6 bodily harm, start fires etc. Any help is greatly appreciated!
 
Hello. I am trying to create a heating element which can reach 200f withing 2 seconds, is no bigger then 1/4" in diameter, can withstand repeated heating and cooling cycles for long periods of time, and is immersible in propylene glycol. I am shooting for the 3.7v to 7.4v area. Those are the only constraints.
I have achieved this with nichrome coils, but the lifespan is simply to short.
Any ideas?
