With this PTC-Heater-Cage you can do the following:
You can safely dissipate lost heat from separated electronics / Generate air recirculation, or ventilate small to medium-sized electronics package housings / Heat small containers such as terrariums, incubators, equipment cases, lipo preheaters, tire preheaters, filament Dryers, and much more.
This two-piece case is available in two variants for 40mm fans with 10 or 20mm thickness. The housing provides space for heating elements or electronic components up to a maximum of: 31.0 x 35.5 x 71.0mm. There is a suitable mounting plate available, which can be screwed to the cage or hold the cage by means of snap mechanism. In addition, matching fan guards are available.
The two half shells are held together by the fan screws (8 pieces M3x30), and offer good mounting possibilities inside and outside. Eight cable channels for 2.25mm thick cables and four slots for fan cables already exist. If required, additional cable feedthroughs can be drilled.
Use sufficiently dimensionally stable printing material according to the maximum temperature to be achieved. For example, you use PLA as the printing material, and in the PLA housing, you operate a PTC heating element with max. 60 degrees Celsius, then you must note the following: The heat exiting directly from the housing and the ambient air must be permanently below 50 degrees Celsius. Choose sufficiently powerful fans and also calculate a lag time for the fans.
If you follow these notes, then even a housing made of PLA for the purposes mentioned may be suitable. And of course you can print the case with completely different materials, but be sure to pay attention to the specifications of the material of your choice
