The controller 130 can control power supply to the electric devices of the construction machine, that is, power supply can be performed through the photovoltaic array 110 or power supply can be performed through the engine 300.

When the secondary heat sink 150 works, one set of electronic fans 151 is turned on first, and when the temperature does not reach the temperature requirement for a period of time, the other sets of electronic fans 151 are turned on to rapidly reduce the temperature. Meanwhile, when the engine 300 is started, the controller 130 controls the photovoltaic array 110 to no longer charge the battery 160, but to be powered by the generator 400; when the engine 300 stops operating, the controller 130 controls the photovoltaic array 110 to supply power to the battery 160; the controller 130 determines whether the operating requirement of the secondary heat sink 150 can be met according to the voltage output by the DC converter 120, and when the output voltage can meet the operating requirement, the secondary heat sink 150 is powered by the photovoltaic array 110, and when the operating voltage cannot be met, the secondary heat sink 150 is powered by the storage battery 160.
