Turbine Generator Cooler for Large Generators

The cooler is designed for use with large generators, lowering the temperature of the air outside the heat exchange tubes (within the generator) by circulating cooling water through the tubes.

The hydroelectric generator cooler operates in an "indirect heat exchange" mode, with the process divided into three steps:

Heat Absorption: During generator operation, components such as the stator and rotor generate significant heat due to electromagnetic and mechanical losses, raising the internal air temperature.

Heat Exchange: Hot air flows over the exterior of the heat exchanger tubes, while continuously circulating cooling water flows through the interior. Heat is transferred through the tube walls from the air side to the cooling water side.

Heat Dissipation: The heat-absorbed cooling water exits the cooler, is cooled via an external cooling tower or cooling system, and is pumped back into the cooler to form a closed-loop circulation. The cooled air then returns to the generator interior to continue absorbing heat from the unit, completing the heat dissipation cycle.
