Development and application of engine cooling fan for harvesting machine
In view of the high engine speed during the operation of harvesting machine,straw and weeds accumulate in front of the radiator under the action of the engine cooling fan,which hindered air circulation and leads to poor heat dissipation performance.A redirecting fan was developed,which controlled the change of the angle of the cooling fan blade through the hydraulic system,so that the fan could be converted between suction and blowing,so as to effectively and automatically removed the debris adsorbed by the radiator and achieve the purpose of self-cleaning of the cooling system.After testing,the performance of the variable direction fan met the requirements of thermal balance,the reliability met the requirements of 1 000 hours of trouble-free,and the noise of the fan body deteriorated by 1.78%to meet the NVH requirements.
