Cube Orange + placed in enclosure. Will the heat damage it?

I have one query related to Cube orange plus heating issue,

i have kept my autopilot in a casing with other electronics like receiver and power module to safe guard it from costumer tampering, so far in 3 -4 months of operation we have not faced any issue related to autopilot heating, even if the operational temperature here is around 28 to 39 degree Celsius.

what could be the long term implications on the hardware and do i need to consider a heat dissipation mechanism for it?
