After the information received about the possible cooling problems of the POP/POP2 devices, I have redesigned the protective case already published and that gave rise to the comments about the heat dissipation areas of the pop2 model and how to improve its dissipation capacity of heat.
I present two proposals and both integrate the same passive heatsink, Be Quiet MC1 Pro wich initially was designed for an M.2 SSD, but which lends itself to being used with our scanner. It is a passive heatsink that integrates two heatpipes that can be obtained on Amazon for around €20. The main difference is that in one the scanner enters embedded and in the other it is fixed by screws. Keep in mind that the scanner must be in contact with the silicone thermal pad and this, in turn, with the heatsink.
The specifications for the unit you listed include a heat pipe, at the cost of a thicker cross-section. I expect that your design will work with the thinner (and less expensive) M.2 2280 heat sinks that are mounted via double-sided tape.
Considering that we need to asure good contact between silicone pad and scanner and that silicone pad is self adhesive may be better the two pieces disign. Two pieces design is mare easier to remove and more safe to install without damage silicone pad.
I want to get this straight in my head; when using the thermal tape with the heat sink, would it be affixed to the scanner before it is inserted in the case? If so, an empty buffer zone would have to be built into the case’s cutout at the top to account for assembly tolerances.
Yes… in both designs the case´s cutout has an empty zone of 2mm around the area reserved for the heatsink…
There are two types of silicone thermal pads, selfadhesive or only for contact. With the design in what scanner enters embeded i would use the contact version at least in the side that touch the scanner to favor the insertion but with the screws version is possible use autoahesive pad and fix pad and heatsink to the scanner permanently.
Today I will upload a new version with little modifications in the heasink area…
I have change holes that originarily were for 3mm screws to 2mm screws because that are what the model of heatsink choose uses and I have partailly retired the wall in wich the heatsink is fixed by screws because of improve the heat evacuation.
