Can a nicrome wire @ 450W 12v reach ~300C

I see.

Most likely going to buy parts today, so I'll update you after

Hopefully it all works out

Lol. Thanks 

 Expect an update in like 5 hours lol

I may be a litte to late but...

Why not just runn the current througth the copper to heat it up? Sure the resistance is very low, so you need a high current transformer, but you can easely salvage them from an old device.

The copper is a housing that is then housed in wood. 

Also, that's a bigger burn hazard than a wire coil. 

This will be used in the school cumputer lab where there will be students walking arround.

 

And, no, you're not late yet lol

Ok, it was just an idea.

Lol. 

Sorry if it sounds like I'm bashing. 

 

I'm mitzvah just, practucallity

Question, just curiousz how would you do this?

You need about 50 to 100 A to heat it up. Collinfurze has a good guide how to make a high current but low voltage supply. Just take a transformer and only use about three turns for the secondary winding.

id guess, a pc psu does not have 50-100a, correct?, esp at 12 v 450W, right?

 

question, this?

also, how many volts would i need at lets say like 8 gauge 3-4 turns or so?

P = U • I

So no, a 450 watt PSU will not work. The resistance of you wire should be way less than the one of the pipe. With your copper pipe this is very hard to do. Also you can calculate the voltage by U = R•I
