I swear I've searched. Has anyone installed a small fan where the fridge flue vent is to just vent out the van whilst parked?

I don't have the original fridge in there, so the flue vent is sealed off and doing nothing. I was thinking of installing a small fan (like a computer fan) on that hole and wiring in to the existing solar to have a little air movement / hot air extraction when parked in the sun. I'd wire it to the solar 12v output side of things to just run off solar and not the battery (since I'd really only need it in the sun).
Anyone done this? Is it even worth bothering with? I'm in Florida and have no A/C, so every degree counts Wink

Not a bad idea seeing as your reefer is gone.

However, that computer fan your thinking of installing at the back end of that vent hole doesn't move enough CFM to make much difference.
Not in the heat & humidity where your at.

It's not uncommon to add a computer fan where the city water port is/was to expel the hot air generated by the fridge. But I don't think a similar fan at the flue vent would be very effective at venting the entire van cabin because of the fan's small size/location. A better solution might be a larger fan at the skylight. I've done this and, while I don't have hard data, it does seem to be mildly effective.

I have also been thinking of how to deal with this heat problem in Florida. The van gets super heated during the day when parked. Our wimpy A/C systems cannot cool it off after it is super heated. The skylight guy used to sell a solar vent that attached to our skylight. You must cut a round hole in our existing skylight. Either a 3" or 4" hole. These vents are used on boats. They are sold by Westmarine. Read the reviews. They seem to poop out after 2 years of use. It is the only thing I have found. They are made by Nicro. Here is Westmarines website:
http://www.westmarine.com/nicro-ventilation--day-night-plus-solar-vents--P012_363_001_516

The other item I looked at is Fantastic Vent (fantasticvent.com). It is a complete replacement of our skylight. The problem with it is that it requires modifying our hatch size. On Westy owner did install one. These vents have excellent reviews. They have one that detects rain and closes the hatch.

I have the Micro stainless vent mounted in my pop top about 2 ft.behind the skylight.

This year it's 10 years old and works fine.

Mind you it's by no means a typhoon, but it moves air.

Thanks TK. I am going to try one as long as I can still fit the Westy in my garage. The vent does reduce my clearance some. I will have to measure. The other option is two skylights and switch for my road trips. Need to garage the Westy due to hurricanes here. It was in the garage during Hurricane Andrew and was fine. Not so for the cars outside.

This is not exactly what you are looking for, but I installed a marine fan by Calframo (model #748) by the kitchen light. It swivels side to side and pivots up and down and we use it as an exhaust fan, cooling fan, hair dryer, etc. and it only uses .25A on high speed. Calframo also has a neat hatch fan but it appears to be too big for our skylights.

I am not using this to cool the van, only to remove heat from behind the stock fridge when camping. Here is a front view and side view. It is angled to keep water from running it. I installed it in the city water port as mentioned above.

For camping on cool enough nights, we use a 12 volt oscillating fan that we clip to the roof cross bar. I notice you are in Florida, if you search the gallery for my username, you will see our camping AC install. I copied many members ideas and added a few touches of my own. mark

The hot air in the van will be near the ceiling, not below the belt line of the van where the vent is located, it is also a very very small vent for the air flow.
Little to be gained cept maybe a dead battery by hooking a fan to it, verses leaving the front widows both opened an inch or few , this will allow cross flow of air as it is near the roof line, so hot air will be removed,

also the fan powered unit will be very ineffective if there are no windows opened. You have to allow air in, to replace what the fan pulls out. If you open the windows you may find you don't need the fan.
