Problems solved by technology
Although this heat dissipation method is simple in structure, the hydraulic oil radiator blocks part of the heat dissipation area of the engine radiator, which affects the heat dissipation effect of the engine radiator, and the heat dissipation efficiency is not high. When the ambient temperature is low in winter, the heat dissipation requirements of the hydraulic system are reduced. This method cannot adjust the heat dissipation with the ambient temperature
In addition, the coolant inside the engine radiator currently flows from top to bottom. This flow method has a short contact time between the coolant and the air. If the circulation flow rate is not large, the heat exchange efficiency will not be high. The low-temperature cycle of the engine belongs to this type.

The invention provides a mining dumper cooling device and a method for cooling and radiating a motor. The cooling device comprises a motor radiator, a motor with a water pump, a power chassis, a fan, a hydraulic oil radiator, a mounting base of the hydraulic oil radiator and a water cooling pipeline. The motor radiator is arranged before the motor. The base of the motor radiator is connected with the power chassis. The fan is arranged on the motor and locates behind the motor radiator. The fan is a suction-type fan. Air passes through the motor radiator firstly and then passes through the fan and the motor. The hydraulic oil radiator is arranged on the bottom of the motor. The hydraulic oil radiator is connected with the mounting base of the hydraulic oil radiator. The invention also comprises the method of using the mining dumper cooling device to cool and radiate the motor. The device has the advantages of simple structure and maintenance convenience and is suitable for large-sized mining dumpers.
Description
technical field [0001] The invention relates to a mining dump truck cooling device and a method for cooling and heat-dissipating the engine, in particular to a cooling device for engine cooling and hydraulic oil cooling, in which the engine radiator and hydraulic oil radiator share a set of water-cooling pipelines, and for cooling the engine. The method of heat dissipation. Background technique [0002] For the operation of large tonnage dump trucks in existing mines, the engine and hydraulic system must be equipped with cooling devices. [0003] At present, large-tonnage dump trucks in mines adopt the form of separating the engine radiator and hydraulic oil radiator. The hydraulic oil radiator uses a hydraulic motor as power, and the hydraulic oil radiator fan is driven by the hydraulic motor to dissipate heat from the hydraulic oil. This heat dissipation method has complex structures and pipelines, and consumes additional hydraulic power, which indirectly increases the he...
