On the right, from top to bottom are the heat exchanger box, the
small fan held down by a yellow strap, and to the left of that is the filter
through which the return air flows from the 3" pipe running near the floor.
On top of the h.e box is the dc power supply which regulates the fan speed.
Two 2" pipes exit from the h.e. box. The front one has a short sleeve which
holds the yellow thermometer. In the vertical section is an anemometer. This
line feeds the plenum cooing loop. The back 2" line feeds the MVD enclosure.
This requires much less air, and the flow is regulated with the big grey valve
with the red handle (partially obscured).
The 2" lines go to the back, and then turn up. The lines have since been insulated.
In the center foreground is the chiller unit which cools the main radiators in the h.e box. Behind the 3" return lines is the second unit which cools the dehumidifier coils in the h.e. box.
In the back, 2 black hoses cme down from the mvd. They have throttle
valves in them to balance the pressure in the MVD. They join into a 3" pvc
pipe, which comes forward and turns to the right towards the filter/pump/
assembly of the previous picture.
A closeup of the new fan assembly. Air comes into the filter can on he
left, and the fan, strapped down with the yellow strap, pumps it up into the
heat exchanger box. On the top left you can see the 2" lines coming out, one
with a thermometer.
This picture shows a view of the left side of the MVD, where the return
hoses connect. You can see the lexan air guides come up, and where they
connect to the endplate, small adapter rings provide a tight seal, and secure
seating (not visible in this picture). The cardboard structures coming from
the left hold the air guides in place. In the real world, the space spanned by
the cardboard holders is occupied by the magnet iron pole tip.
This is the same view on the other side, where the cool air enters. The
cardboard spacer of the plenum air channel can just be seen in the lower left
corner, and I removed the spacer on the enclosure air channel to provide a
better view. The adapter ring and flange is what is taped to the endplate, and
it makes a tight seal with the small round flange on the lexan air guide. In
the distance, Dave is working on the silicon.
