venting a 12v compressor fridge

[the1andonly]

I would like to put my 12v compressor fridge in a cupboard/ box.
how much ventilation is required to allow it to function correctly. 1" or 2" gridded hole? low or high?

Not a lot, our compressor is mounted over the rear air con. unit behind the fridge itself and only has a very small vent panel in the conversion woodwork, but there is also the ventilation behind the plastic trim that has been removed to allow its fitting.

Thanks Geoff
my side panels will be in place and insulated with a wool synthetic mix.
any real venting will be into the van area.

I have a Vitrifrigo C42L, with a remote compressor (Danfoss BD35).

I have mounted it inside the main cupboard om my conversion, transverse with the tail end over the wheelarch :



Once the main face of the conversion is in place, the fan draws air from inside the cupboard, and vents it out into the van through a timber vent:



The seat pretty much gets in the way of this vent, but the fridge seems to do OK. If I was doing it again, I'd probably try yo avoid this clash with the seat though!
