I was wondering if these server racks in space would need to be specifically designed for enough radiative cooling. Apparently the answer is “yes”: the radiators would be expansive and placed on the reverse side of the solar panels.
Starcloud is developing a lightweight deployable radiator design with a very
large area - by far the largest radiators deployed in space - radiating primarily towards deep space, which has an average temperature of about 2.7 Kelvin or -270°C. The radiators can be positioned in-line with the solar
arrays as shown in Figure 3, with one side exposed to sunlight.
