Automobile crane and ventilation control method

Abstract

The invention provides an automobile crane and a ventilation control method, and relates to the technical field of automobile cranes. The automobile crane comprises an engine hood and an active ventilation system, the engine hood covers an engine and forms an engine compartment, the active ventilation system comprises a controller, a ventilation window and a closing structure, the ventilation window is formed in the engine hood and communicates with the engine compartment, the closing structure is movably connected to the engine hood and can selectively close or open the ventilation window, and the controller is electrically connected with the closing structure and used for controlling the closing structure to move relative to the engine hood; and the invention further provides the ventilation control method which can be applied to the automobile crane. According to the automobile crane and the ventilation control method, the heat dissipation efficiency of the engine can be improved, the stable operation of the engine is guaranteed, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to the technical field of truck cranes, in particular to a truck crane and a ventilation control method. Background technique [0002] When the truck crane is driving in high temperature weather, especially under high torque conditions, it often occurs that the engine water temperature is too high and the engine stops, or the gas in the engine compartment is overheated and the thermal sensor is damaged. One of the reasons is that the engine cover hinders the outflow of high-temperature gas behind the radiator, causing it to return to the front of the radiator to cause hot air to flow back, or to stay in the engine compartment, thereby reducing the cooling efficiency and the temperature near the thermal element is too high. Contents of the invention [0003] The objectives of the present invention include, for example, to provide a truck crane, which can improve the cooling efficiency of the engine, ensure the stable operation of...
