Engineering machinery cooling fins

Engineering machinery cooling fins

   Engineering machinery has the characteristics of full load work, high ambient temperature, large vibration impact and poor working conditions. Especially Engineering machinery working in Gobi and the desert, are very vulnerably impactedby blowing dust from sandstorm,and the engine compartment is impacted by high winds,High-speed sand will damage the radiator fin and block its flowing, thus affecting the normal use of the radiator module. Therefore, Engineering  machinery thermal management system, rarely to use the open shutter tube radiators , but using the no-open window tube type, waveform or serrated radiator. However, the shutters can damage the air flow in the attachment layer on the surface of the heat sink to improve heat dissipation. Experiments have proved that radiator with opening louvers is 1 to 3 times greater than the no open shutterradiator . How to effectively improve the structure of the radiator, so that it can not only resist wind and sand impact but also have a high heat transfer capacity,it will has great practical significance and application value for the stable work of Engineeringmachinery.



    The Engineering machinery cooling fins includes the fin body, and a plurality of wave-shaped heat dissipating passages arranged side by side on the fin body. Each of the corrugated radiating passages sequentially comprises a windward section, a transition section, and a heat-dissipating section,and the walls of the windward section, the transition section and the heat dissipation section are gradually thinned, and the side surfaces of the outer surface of the heat dissipation section are provided with shutters. The angle between the louver and the flow direction of sand dust , largely Improve the cooling capacity of the radiator. Therefore, the Engineering machinery radiator is not only to resist wind and sand impact, but also has a high heat exchange capacity.
