It looks exactly like the Nitecore EC4 line of product.
Firelight2:
Having fins parallel to the body of the light does offer some advantages. You could have a fan blow down the length of the ribs for much superior cooling.
I’m not sure how you’d machine it though. I don’t think you could do it on a lathe. It might be really expensive to machine.
Easily done on a 4-axis machine or turning center with live tooling and auto bar feed… unattended 24/7 no problems whatsoever.
Cereal_killer:
More heat is transfered from the lights body into your hand (liquid cooling) than from the lights body into air (air cooling).
Flashlights arnt a new thing, if vertical ribs worked better they would have been implemented by now. Seems to me like all vertical ribs would do is decrease the contact area between hand and light body decreasing the cooling ability of the light…
Not saying it won’t look BA, but it won’t work any better.
Also since you’ve brought up fans what’s your plan for water resistance? Fans, especially tiny ones die when submerged cause the force needed to move liquid is so much higher than air their little motors just instantly die regardless whether they’re IPX sealed or not. On the few forced air cooled lights now I believe the fans are usually designed to sense water egress and shut down immediately to prevent burning up the tiny little motors.
A brushless motor fan would inherently be water-resistant; you just have to keep dirt and debris out of the bearings and rotor. And the electronics that drive the motor.
