Embodiment
By describing technology contents of the present invention, structure characteristics in detail, being realized object and effect, below in conjunction with mode of execution and coordinate accompanying drawing to be explained in detail.
Refer to shown in Fig. 1 to Fig. 4, the lumbering type Bulldozer heat radiation of present embodiment, comprises motor outer cover, engine cooling apparatus and wind scooper.
Described motor outer cover comprises that front shroud 2, middle cover 5, portal frame 7(are back cover), side guard shield 6, frame 8 and end guard shield 9, the motor of bulldozer and engine cooling apparatus (comprising radiator 3 and cooling fan drive device 4) are positioned at bulldozer front portion, be contained in frame 8, by motor outer cover, be surrounded.On described middle cover 5 and side guard shield 6, offer respectively the ventilated port of offering on more than one ventilated port (it is left that three places that label is as shown in Figure 1 A are side guard shield 6(), label is as shown in Figure 2 that three places of B are the ventilated port of offering on middle cover 5), described ventilated port place seals with pore web plate, the mesh aperture of described pore web plate is not more than 4mm, to prevent the foreign material such as mosquito, leaf from entering motor outer cover, by wind, blown into the interior obstruction ventilation flue of radiator 3, affect radiating effect; For avoiding wind speed too fast and guarantee that enough ventilation and heat area and air inflow, ventilated port will open greatly and many as far as possible, the mesh gross area of pore web plate is not less than the windward side area of described radiator 3; In order to make pore web plate possess enough rigidity, collapsed preventing by tops such as branches, described pore web plate preferably adopts the pore web plate that is not less than the steel that 3mm is thick.
