| 摘要 |
The invention concerns a Foucault current braking device, comprising at least a heat exchanger for dissipating thermal energy due to Foucault currents when braking. The invention is characterised in that each heat exchanger is arranged to define a predetermined cooling liquid path to minimise pressure drop and maximise the flow rate of the cooling liquid flowing through the exchanger, so as to reduce working temperature variations of the heat exchanger, the device comprising two symmetrical heat exchangers, whereof the water inlets (72, 73), circuits and outlets (75, 76) are symmetrically arranged so as to compensate forces due to the cooling liquid currents thereby minimising the corresponding residual torque. |
