摘要

The invention relates to a rock drilling rig, a method for controlling the temperature of its drive equipment, and a liquid cooling system. The rock drilling rig includes combustion-engine-free drive equipment, which includes electric components for affecting transfer drive. The rock drilling rig is also provided with a liquid cooling system, to which one or more electric components affecting the transfer drive are connected to be cooled by the system. The cooling of the components is controlled by a control unit according to a strategy set therein. The cooling system may additionally be precooled before the transfer drive.
