Battery Powered Nichrome Heating Element (80 Degrees)

AI Thread Summary
Using nichrome wire for a battery-powered heating element to reach 80-100 degrees Fahrenheit is feasible, as nichrome can handle much higher temperatures. The discussion highlights concerns about safety and efficiency, particularly for small-scale applications to avoid hazards like fires. One user aims to create a heating element that can quickly reach 200°F while being compact and durable, specifically for immersion in propylene glycol. The lifespan of nichrome coils is a concern, prompting inquiries for alternative solutions. Overall, the conversation revolves around optimizing nichrome for specific heating requirements while ensuring safety and longevity.

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?
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...
