Radiator: High Efficiency via Counter Current Flow
In order to dissipate the heat that is absorbed by the water, a radiator is part of the circuit. This is equiped with a large fan (12 cm diameter) that allows for quiet operation. The fan is factory-set for a voltage of 12 Volt - for our purposes, we ran it at 5 Volt using an adapter. Despite the low rpm, the flow volume is enough to effieciently cool the circulating water. The intricate cooling fins of the radiator ensure perfect heat transfer between water and air.
