An apparatus for controlling a temperature of a lubricant for a drivetrain of a wind or water turbine includes a circuit for the lubricant 32 connected to the drivetrain 8; a heat exchanger 10 connected to the circuit for the lubricant, the circuit for heat exchange fluid 34 connected to the heat exchanger, and the circuit for heat exchange fluid further connected to a source of thermal energy and to a sink of thermal energy, such that a controller 36 regulates a flow of thermal energy between the lubricant and the heat exchange fluid via the heat exchanger. Preferably the lubricant circuit includes a reservoir 7 in which the heat exchanger is located inside. The thermal energy source may be an electric heater or solar thermal panels and the apparatus may also comprise a generator or a power convertor. |
