Convectors are e.g. used in mobile homes for heating purposes. They
usally consist of a tube (0.4 m to 1,5 m or so) with attached thin
aluminium cooling fins each 5 mm. In horisontal position the ambient
cooling capacity is ~0.5 kW/m but with appropriate fans you can boost
this 2 to 3 to ? times.
In my CM-ARC setup I have a 1 m reflux convector with 11 small
"PC-fans" attached and an 0.7 m product condensing convector with a
normal household fan. The reflux convector is almost horizontal
(50-100 mm "angle") and the other one is vertical. That's the CM-part.
To accomplish an ARC I use a thermostat with a 0.1°C accuracy. The
sensor is placed 2/3 from the top of the column (1.5 m) and controls 6
of the fans, the others work all the time. When temp gets over ~80°C
these 6 fans start working and gives full reflux for a while until the
temperature gets below the set temperature. Works like a clock and I
run my boiler to 100°C without a trace of tails!
