PARTITION PLATE STRUCTURE IN CONSTRUCTION MACHINERY

摘要

PROBLEM TO BE SOLVED: To prevent maintainability from being impaired while reducing the size of a pipe through hole formed in a partition plate 19 when preventing cooled air on an engine chamber E side from flowing to a heat exchanger chamber C side in a reverse direction by partitioning an engine chamber 13 arranged behind a hydraulic shovel 1 into the heat exchanger chamber C and the engine chamber E via the partition plate 19 fitted to the upper surface of a fan shroud 17. SOLUTION: The partition plate 19 is divided into upper and lower plates 24 and 25, and through holes 20a, 21a, 22a and 23a with a pipe freely passed therethrough are formed in divided edges facing each other. The maintainability of the partition plate is excellent while the through holes do not reach the lower edge thereof. COPYRIGHT: (C)2004,JPO
