A lot of the credit for actually making it happen goes to our kitchen re-modelers, Eric Christ of Halperin and Christ Building and Design and his nephew  Noah, as well as the cabinet maker, Jeff Ward. First, they removed our old cabinets and exposed the old vent. This was a single vent that was fairly large. Perhaps it was divided into two vents originally, but what we needed for the dimensions of the new cabinet was to seal off some of this vent and then to cut a new one up higher.

When the new cabinets arrived, they cut holes in the back for the new vents before installing the cabinet on the wall. For louvers, we used a pair of heating registers with little levers for opening and closing. After the cabinet was installed, the new vent was cut in the side of the house to match the upper cabinet hole (See Intro Photo). A strip of adhesive foam insulation was also added along the vertical edge, to prevent air exchange with the kitchen.  Soon similar pieces of insulation will be added at the top and bottom.

Next, we added insulation to the back and sides of the cabinet, and Eric made some custom pieces of wood to cover the insulation and line the cabinet. The wood and insulation in the back was given holes that matched the vents and into these holes the heating registers were mounted.

On the side walls, we drilled sets of holes for the shelf pegs. The wire cloth was cut with a grinding wheel, and then bent to the right size by a metal shop.

Finally, insulation was cut for the door. It has not yet been permanently installed (still trying to figure out how to do this), but it's put in place for most of the day, except when we are home, cooking.

For now, the thermometer probe has just been inserted through the gap at the bottom of the door, but soon we'll drill a hole in the bottom of the cabinet and mount the thermometer on the wall.

How marvelous! Is there screening between the external vents and your cupboard to deal with insects?

For permanently installing the insulation, try 'construction adhesive'. Comes in big tubes just like caulk. I used some to reinstall a body molding strip back onto my truck after the body shop's repair tape didn't hold up to the wind and elements.

it would have to be "food grade" adhesive. Stuff like liquid nail would leach noxious fumes into the food.
personally? I would use double sided foam tape, just clean all the surfaces very well with Iso-alcohol before applying

Cool!
Do you have a way to keep cool air from pouring back out the bottom vent during the day?  How about hanging very thin film (like dry cleaner bag material) from the inside top of lower vent and outside top of upper vent.  The vent flapper film would self open to vent heat but hang closed to trap coolth. (Also consider hanging a white sun reflective sheet 6" from the outside of the wall to keep solar heat away.)
