The front casing was redesigned and the vents were removed to prevent dust from entering the vents. The re-design took the following thermal recommendations from Intel RealSense into account:
The back casing is lengthened and pushed to the front while the front casing is made larger and longer to allow for the structure to enclose the camera without directly wrapping around it tightly. bottom cut for the vents has been removed and the top has been kept open with an additional part added to mount two 20mm x 20mm fans
Dust mesh filters were designed to be placed above and below the case.
Rubber sealing has been added between the front and back casing as well as the front casing and camera lense allowing for additional protection against dust.

Passive Cooling Recommendations:
material that is the same or similar in nature (equal or lower thermal resistance or high conductivity) as the peripheral housing that the D400 Series depth cameras are made from. Material – Aluminum 6000 series.
series depth camera can be increased by a factor of 2X. The larger the mounting bracket mating surface area to the depth camera the better. o Reduction of mating surface imperfections, defects, roughness and gaps is recommended. Any increase in defects in the material can increase the thermal contact resistance, reducing effectiveness of heat dissipation of the thermal solution. Attachment options should be comprised of epoxy compounds or thermal tape/paste.
from the D400 series depth camera. Use of a material such as Aluminum 6000 series or similar with equal or lower thermal resistance to the mating surface is recommended. Active Cooling Recommendations:
increase the complexity of system integration substantially. The use of a fan with direct air flow to the depth camera (back mounting surface 2X M3 screws) is preferable.  |
