Abstract

The invention relates to a cooling device of scooptram mechanism, comprising a vehicle frame, an outer cover, a cooling fan and a heat dissipating device. A mounting deck is fixed on the vehicle frame; the heat dissipating device is fixed on the mounting deck; each component of the heat dissipating device is arranged in three rows in fore-and-after direction; the cooling fan is positioned at the back row and installed at the tail part of the vehicle frame; a water radiator is positioned at the middle row; a charge air cooler and an oil radiator are positioned at the front row; thermal baffles are positioned in front of the charge air cooler and the oil heat radiator; the outer cover is installed on the mounting deck so that the outer cover and the thermal baffles as well as the space surrounded by both form a cooling chamber positioned at the back side of an engine and that the cooling fan, the water radiator, the charge air cooler and the oil radiator are positioned inside the cooling chamber. The cooling device of the invention is separated from an engine body via the cooling chamber, and the air draught is basically in the state of stable flowing when a suction cooling fan works; therefore, the structure reduces the air friction, reduces the working pressure of the fan and has better wind cooling effect.

Description

technical field

[0001] The invention relates to a component of a scraper machine. Background technique

[0002] Scrapers include loaders and motor graders. The cooling device of the loader or grader usually uses the radiator as a heat exchanger and cools the cooling water and high-pressure exhaust gas of the engine and the power oil and lubricating oil of the hydraulic system of the loader in an air-cooled manner. Among them, the component that cools the engine cooling water is the water radiator, the component that cools the high-pressure exhaust gas of the engine is the intercooler, and the component that cools the hydraulic oil and lubricating oil of the hydraulic system is the oil radiator.

[0003] The function of the water radiator is: after the cooling water is pumped out by the water pump, it flows through the engine block to take away heat, then enters the water radiator for cooling, and then returns to the water pump for circulation.

[0004] The role of the inte...
