Ideas for keeping frig in outdoor kitchen cooler?

I don't have a outside kitchen so I haven't had the problem. I'm going to take a guess at a solution.

It would be great if you could find a way to vent the compartment out to the roof of the camper. Even if it were smaller PVC pipe. Then you could add a fan to the pipe and suck the heat out the top.

They even sell Solar powered fans for vent pipes to keep your holding tanks vented better.
