Anyone seen/done custom radiators?

post #1 of 3
Thread Starter 
I'm curious if anyone has seen anything or knows anything about making/modding custom radiators for liquid systems. I have some ideas that would benefit greatly from curved and/or round radiators. Even a long, skinny radiator would open up some interesting possibilities.

The reason you won't see such a broad variety of radiators is the cost of tooling. Radiators are fairly simple, really just some tubing with the fins attached, and a couple end cap chambers with your choice of fittings... but making the dies to stamp out the parts, and the fixturing to solder them up takes time and resources, and for one offs isn't worth it (from a business standpoint).

If you'd like to make your own, take a look around at stuff that's already available on the market with an eye toward taking parts of it and adapting it to your needs. Motorcycle stuff, some smaller car stuff, racing supplies, refrigeration and other industries use radiators for all types of applications. You'll need to be able to solder up at least a custom set of fittings on the end chambers to adapt them. You may have to hack them apart and resolder to meet your size needs.

Well, it depends on the kind of radiator. The common type of radiator, like TLHarrell describes, is time consuming and expensive to produce in custom sizes and shapes, but there are other possibilities as well. Not all exchange heat as well as the standard type does, but I've seen some interesting designs. It really depends on the amount of heat you want to transfer away and how much space you have to do it.

As for curved radiators, I've seen the ones used in many home AC unts curved. They also rely on a slightly different design than your usual PC watercooling radiator, with tubes going back and forth through the fins as one line, instead of several water channels in parallel going in between the fins. These can be cut into parts and segments with tubing inbetween. Those are the only "DIY" kind of radiators I can think of that are still up there in terms of effectivity.
