Example Embodiment
[0018] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.
[0019] Such as figure 1 As shown, a hydraulic oil heat dissipation system, which is located in the hydraulic system of a construction machine, includes a hydraulic oil radiator 5, a fan 3, an air-cooled motor 2, a controller, a temperature sensor 4, and a hydraulic pump 1. The air-cooled motor 2 is a variable hydraulic motor, including a displacement control oil cylinder 7 and an electric proportional control valve 6. The temperature sensor 4 is installed at the oil inlet of the hydraulic oil radiator 5 to detect the temperature of the hydraulic oil at the oil inlet of the hydraulic oil radiator 5. The air-cooled motor 2 drives the fan 3 to dissipate heat from the hydraulic oil rad...
