Keg King, Kegerator Fan Mod

thingiverse

A replacement fan housing for the Keg King Kegerator should improve refrigerative efficiency and reduce the chance of warm spots within the fridge. It utilises the existing 60mm fan but points the airflow in a useful direction. The mod also adds three hanging points for gas and beer lines. This modification is for series three kegerators from Keg King, but it may fit other series and brands that use a 60mm fan mounted to the inside wall of the fridge. The manufacturer's mounting method does not permit any useful airflow; instead, the fan blows towards the door of the fridge at a slight angle, swirling air around to reduce warm spots, especially those furthest from the heat-exchanger at the rear of the fridge. The number of kegs and other items in your kegerator will affect air circulation. Position contents to enable airflow if possible. If you replace the OEM fan with another, use a low-current fan; high current fans might over-stress the driver circuit. The OEM fan in my fridge was rated at 12VDC @ 0.10A (or 100mA), but yours may vary. Files: 60mmFanMount.2.stl is the basic angled fan mount, 60mmFanMount.3.stl has three hose holders with a very positive grip, and 60mmFanMount.4.stl is similar but should be kinder to your hoses and has more clearance for one of the nuts. Print Settings: Rafts - No, Supports - Yes, Resolution - 2mm layers, Infill - 50%, Notes - Three shells. This mod may be printed in ABS or PLA or any other hard plastic that is okay with cold temperatures and occasional humidity. Post-Printing Steps: 1. Turn off your kegerator. 2. Remove the two screws on the fan cover. 3. Remove the four screws from the fan, being careful not to damage the fan blades. 4. Disconnect the fan cable and remove the fan. The plug needs to be pinched to release it from the socket. 5. Fasten the fan to the new mounting using four 4mm by 25mm machine screws with four Nyloc nuts and two washers. The fan should blow towards the front of the fridge at a slight angle, with the blades facing downwards. Step 7: Install the new fan mount inside your kegerator. Plug in the plug and observe the polarity; it should only fit one way. Fit the new mount to the kegerator using the old fan screws with standoff tubes fitted to the screws. Do not tighten the screws until you are sure the cable is not pinched between the mount and the fridge. Step 8: Turn on your kegerator and test your new fitting. If the fan is noisy, check that the screws are not overly tight; they can distort the fan chassis and blades may strike the sides. Step 9: Pull a cold one and marvel at your DIY abilities.
