Ducted cooling for 20x40 V-Rail

thingiverse

This is a ducted cooling system, and "Name" sums it up nicely. It's designed to attach directly to a 20x40mm V-Rail. The fans are Sunon 40x40x28mm MagLev (GM1204PQV1-8A), which can be purchased on Amazon at https://www.amazon.com/gp/product/B00118ZWYY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1. The tubing can be any 1" ID spiral pipe, and this is what was used: http://www.ducting.com/ambient-air/dehumidifier-ducts/pvc-flexduct-general-purpose-blue.html. Note that on request, the system has been assembled using standard CPAP hose, which works fine but with less airflow. The cooling shrouds are missing at present, but a dual tool Flex3Drive is being awaited in order to obtain the necessary measurements. However, the intake/exhaust manifolds should bolt onto any 40mm fan housing. Update: A lower intake model has been added as well as some images of the system installed and running. It's likely that a hose clamp will be created to keep everything in place and to arrest vibrations. The STL will be posted when it's finished. Update: An intake manifold for a smaller format AC unit has also been added, along with some threads that are being experimented with to make hose connection easier. Update: A hose clamp has also been added to keep everything neat and tidy.
