Heater Booster | Radiator Booster

This is a heating booster for Vogel & Noot Type 21 two-layer compact radiators in widths 132cm and 62cm at 80mm depth.

The system works with standard 8cm PC fans (3 pin) which connect the printed segments together. In addition, the segments are connected to each other with small filament pieces that are inserted into three holes on the sides. Squeeze the filament a little with pliers before inserting it for more friction. The segments adhere to the radiator with pressed-in round 10x3mm neodymium magnets. There are recesses in the segments for the cable feed-through, so that four fans each can be connected in parallel via a Molex distributor.

For reasons of efficiency, as little air as possible should escape at the bottom and sides, so the system is closed at the bottom with plates between the fans and via attachable side plates. The side elements for holding the control board differ in length and number for the 132 and 62cm wide radiators and are named accordingly. All other segments are identical and differ only in terms of number.

Power is supplied via an 8mm hole in the controller segment, through which a cable can be fed or a connection socket installed. For fan control I used a 12V relay control board with temperature sensor, which is mounted with M3 screws on the holes provided. To adjust the fan speed, an adjustable DC-DC step-down converter is recommended. With this converter, the fan voltage can be reduced from 12V to approx. 7-8V, so that the fans run quietly but sufficiently strong.

To connect the fans to the voltage converter, I constructed a Molex adapter into which 4 standard straight 2.54mm pin headers are inserted. The 3pin fan connectors are plugged into them. Alternatively, you can just solder everything together.

Print the segments in STL orientation in 0.3 layer height with 20% infill and the Molex adapter in 0.2 layer height. Make sure that the raised plates (sealing between the fans) are aligned in the direction of the Hotend fan, otherwise they will be easily bent away by the airflow during printing.

There are recesses in the segments for the cable feed-through, so that four fans each can be connected in parallel via a Molex distributor.

For efficiency reasons, as little air as possible should escape at the bottom and sides, so the system is closed at the bottom with panels between the fans and via clip-on side panels. The side elements for holding the control board differ in length/number for the 132 and 62cm wide radiators and are named accordingly. All other segments are identical and differ only in terms of number.

Power is supplied via an 8mm hole in the controller segment, through which a cable can be fed or a connector jack installed. For fan control, I used a 12V relay control board with temperature sensor, which is mounted with M3 screws on the holes provided. To adjust the fan speed, an adjustable DC-DC step-down converter is recommended, which can be used to reduce the fan voltage from 12V to about 7-8V so that the fans run quietly but with sufficient power.

To connect the fans to the voltage converter, I constructed a Molex adapter, into each of which 4 standard straight 2.54mm pin headers are inserted. The 3pin fan connectors are plugged onto them. Alternatively, you can just solder everything together.

Print the segments in STL orientation at 0.3 layer height with 20% infill and the Molex adapter at 0.2 layer height. Make sure that the raised plates (sealing between the fans) are aligned in the direction of the hotend fan, otherwise they will be easily bent away by the air draft during printing.
