[Brian] came up with an interesting PC cooling setup. He lives up north where it’s chilly in the winter. Using a bit of dryer ductwork and he was able to harness the outside air to cool his box. The system uses a window insert along with a dryer hood to suck in the outside air with a PC fan. We hope the air is adequately warmed, as it is exhausted into the room. Join us after the break for more pictures of his setup.
Below are the duct fitting he used. This includes a hood for outside, a damper which closes with gravity, some scotch brite pad to act as a filter, a flexible duct, and a quick connect.
The next three images show the construction of the window insert. The filter and hood are on the outside of the board, and the quick connect on the inside. Although [Brian] shows a damper in his parts image, we’re not sure where that is actually installed. We think it would be best for this damper to have a servo actuator, as gravity won’t be enough to keep the wind from forcing it open.
