Radiation between Parallel Plates

Online calculator for heat radiation exchange between two parallel plates.

It is also approximately valid for the net radiation exchange between two PCBs provided that the plate temperatures are set to the average temperatures of the PCB.

Gap
The gap is the wall to wall distance between the two plates.

Emissivity
The emissivity for most surfaces is around 0.9. An exception from this rule of thumb are blank untreated metal surfaces for which the emmissivity can be as low as 0.1.

Note
The values inside parentheses are the results of the proceeding calculation.
