Only the bit in the Rubidium tube has to be heated to a high temperature.
The rest of the electronics have to
be kept within their spec.
In practice, I have found that mounting an LPRO on to a chassis, or using a
finned heatsink only slightly larger than
the baseplate, will work ok.
There is a lot about this subject in the archives

Subject: Re: [time-nuts] LPRO Heat Sink?
I'm new to this, but it sounded more like this is to be a thermal
mass to minimize temperature swings.
Why would you want to efficiently cool something that you are trying
to heat and maintain at a constant temperature?
just curious in Medina, OH

Monsterously thick will NOT do it. All that does is increase the heat
capacity of the HS, not it's ultimate thermal resistance (W/deg).
You need surface area...
You need both. A 10 m x 10 m piece of aluminum foil won't do much,
either, despite having a very large surface area.
