In prototyping or small build runs, a groove ring can be machined for bending the heat pipe by hand as the sintered wick heat pipe is fully annealed and soft. If bending is performed adequately and according to Enertron's 3x rule, the heat transporting capability will NOT be affected up to a 180 degree bend.Apr 18, 2019
How do you bend a flat heat pipe?
Heat the pipe and start making a small bend of a few degrees, reheat it again and bend it a few degrees further, repeat until bent enough. You're right about your foil thing. Heat pipes are the most effective thing in transporting heat, not dissipating. They just relocate the heat from the source to somewhere else.Feb 22, 2018
What is are the effect of bends in a heat pipe?
The bending affects heat pipe by wick deformation that obstructs liquid flow. The flattening affects the thermal resistance by the collapse of wick structure which causes a broken liquid path of returned working fluid from the condenser to the evaporator and by liquid clogging in the condenser.Feb 5, 2019
Can heat pipe be bent?
Bendable heat pipes, which can be bent after fabrication as needed, are novel devices for thermal management. The effect of bending on temperature drop, performance and performance limits has also been investigated.
How does heat affect pipes?
Yes, hot weather can cause pipes to burst, too, though not as commonly as freezing temperatures. Hot weather causes the pipes to expand, and if they are aging or previously stressed, they may spring leaks.Oct 18, 2019
What is bend flattening?
If too much stress is placed on the outside radius during the bending process, the tube can't maintain its shape, causing the outside to bend in, flattening the tube. This is fixed by reducing stress and utilizing a larger bend centerline radius.
How do you bend copper pipe without a bender?
- Straighten out the copper pipe or tubing. ...
- Tape off the bottom of the copper pipe with duct tape or electrical tape.
- Fill the copper pipe with sand or salt, using a funnel.
- Tape up the other end of the pipe.
- Bend the pipe to the desired curve.
