The hydraulic oil circulating cooling system comprises a hydraulic oil source, a hydraulic power source, a hydraulic execution element, a bridge box cavity and a heat dissipation element which are connected in series, and hydraulic oil containing an extreme pressure anti-wear agent is injected into the hydraulic oil source. The hydraulic oil circulating cooling system is used for the layout of the whole vehicle, main parts of the whole vehicle are contained in the hydraulic oil circulating cooling system for cooling the whole vehicle, the heat dissipation capacity of the system is greatly improved, the requirement for the power of a radiator with independent heat dissipation is reduced, and even a special radiator and a special hydraulic oil tank are not needed; and the structure of the whole vehicle is easier to upgrade and optimize. The invention is suitable for various engineering machinery vehicles, and has high popularization and applicability.

    本发明公开一种伸缩臂叉车的液压油循环冷却系统及循环冷却方法,包括串联连接的液压油源、液压动力源、液压执行元件、桥箱腔体和散热元件,所述液压油源中注入有含极压抗磨剂的液压油。本液压油循环冷却系统用于全车布局的液压油循环冷却系统,将全车主要部件都纳入液压油循环冷却系统,进行全车冷却,极大的提高了系统散热能力,并对于独立散热的散热器功率需求变小,甚至不需要专门的散热器和液压油箱,更易于整车的结构升级优化。本发明适应于各类工程机械车辆,推广适用性很高。
