Study On The Forced Cooling System Of The Microware Road Maintenance Equipment

The heating equipment of the microware road maintenance equipment is constructedfrom a arrays of heating units configured by the magnetrons, which would produce lot of heatwhen it working. The stability of the magnetrons are impacted by continuously temperaturerising. Furthermore the magnetrons would be damaged by drastically temperature rising.So the cooling system plays a critical role in prolonging the service life and workingefficiency of the magnetrons. The reasonable design of the cooling system also plays a keyrole in the overall design.The analysis of the forced cooling for heat dissipation is presented in this paper. Theeffects of the location of air vent, height of the heating wall, air velocity through air intake,the air convection angle through the air intake and efficiency of the secondary air etc. on theefficiency of the forced heat dissipation are investigated by the simulation method. Thesimulation results provide a meaningful instruction for the design of the cooling system of themicroware road maintenance equipment. The simulation results are concluded as follow:The air inlets and air outlets are located on the bottom of the heating wall, the air isintroduced by the air blower for the top of the heating wall, and go into the interior of theheating wall through the channel. The angle of inclination between the air inlet and thehorizontal plane is15°,and the tilting of the E face make better efficiency the tilting ofthe H face. The interior channel for air convection could improve the efficiency of the heatdissipation. The max height of the heating wall is limited in300mm, the min height of theheating wall depend on the practical situation, the tilting secondary air inlet also canimprove the efficiency of the heat dissipation.
