Some time back I designed and 3D printed a 3 fan cooler for my Xiegu XPA125B HF amplifier that stops the heat-sink from becoming heat saturated.
Having printed this for Steve, M0XVT and myself we’ve thoroughly tested it and found that it greatly reduces the temperature of the amp during operation.
I’ve now decided to make the .STL file available for download so that those who have their own 3D printer can print their own cooler for the amp.
The 40x40x10mm 12v fans that fit onto the mounts on the cooler module can be obtained from Amazon. (Note: Originally they came in packs of 4)
I’m happy to print this for people who don’t have a 3D printer of their own, please contact me via email for a price.
For those who have their own 3D printer, the .STL file is available below for download.
Please note that I am releasing this STL file into the public domain for non-commercial, personal use only.
More soon …
