Add ventilation to electrical compartment?

IN my OFF-ROAD POPUP trailer I have the cabinets all lined up to each other as the wrap around around the trailer.



My on-board converter is mounted in the under seat storage compartment next to the stove cabinet shown above. There is a partition here with the converter in the front area and the push-in shore power cable in the back compartment. I added some small round vents from LOWES in each of the compartments that is under the wrap around seating storage compartment which creates a positive ventilation which exhausts out a bigger vent installed next to the entrance door. I got the fan-grill-thermostat from AMAZON


On the inner partition that separates the converter unit and the shore power cable storage area I added a 6-inch 12VDC axial fan that is under thermostat control set for 80 degrees which will pull in fresh air through the converter from panel vents and exhaust out the inside vent near the entrance door. I can also leave the SHORE POWER CABLE door opened to allow the exhaust to exit the trailer as well. This keeps my converter unit running cool...

I have a similar arrangement for positive ventilation in the large storage cabinet next the tent bed on the right in the above floor plan where my PD9260C OFF-ROAD converter is installed for use when camping off the power grid.

The positive ventilation through the cabinets also helps keeps things from freezing up inside the cabinets when the outside temperature gets down below freezing...

Got this idea from one of the guys up north that lives 24/7 in their RV Trailer setup... Really works great for us...

I'm surprised it doesn't have a fan to help control converter temps....they get hot

I would add some ventilation and a small fan

Anything you can do to allow for ventilation and to decrease the temperature of electronics is a good thing. If your electronic space is sharing air with the bathroom, make sure there is a positive flow into the bathroom and not the opposite. Moisture around electronics is a bad thing.

If you can add a small muffin fan into the compartment, it will increase the air exchange greatly and not at that great a cost in power.
