Title:
建設機械のエンジンルーム構造及び建設機械
Document Type and Number:
Japanese Patent JP7047650
Kind Code:
B2
Abstract:
To provide a technique which can suppress heat exchange rate from decreasing in a construction machine with an air-cleaner above an engine.SOLUTION: A construction machine includes an engine 61, a fan 63, a radiator 65, an air-cleaner 69 and an engine bonnet 5. The engine bonnet 5 has an upper surface cover 51 that functions as a part of the upper surface of an engine room 30 and has an upwardly convex shape. The space formed between the inside of the upper surface cover 51 and the air-cleaner 69 functions as a first exhaust flow passage PT1 until first air is emitted through a first exhaust port 510. The space formed between the engine 61 and the air-cleaner 69 functions as a second exhaust flow passage PT2 until second air is emitted through a second exhaust port 83. A partition plate 77 is provided between the first exhaust flow passage PT1 and the second exhaust flow passage PT2.SELECTED DRAWING: Figure 6
