Abstract:

Provided is a package-stored engine work machine that aggregates cooling wind intake ports at one location despite an electrical equipment housing space that houses electrical equipment being configured partitioned in twain. In the package-stored engine work machine (1), an engine (5) is disposed in the lower space (4) of the package (2), and the electrical equipment is disposed in the upper space (3) of the package (2). The spaces are partitioned in a manner so as to be provided with: a high-heat-release chamber (33) in which high-heat-releasing components are disposed; a low-heat-release chamber (34) in which low-heat-releasing components are disposed; and an air intake fan chamber (35) in which an air intake fan (36) is installed that sucks in outside air through one air intake port (39d). The package-stored engine work machine (1) is provided with: a high-heat-release chamber cooling pathway (Q) by which outside air (F) from the air intake port reaches the air intake fan chamber via the high-heat-release chamber and a first interconnecting opening (74); and a low-heat-release chamber cooling pathway (R) by which outside air from the air intake port reaches the air intake fan chamber via the high-heat-release chamber, a second interconnecting opening (75), the low-heat-release chamber, and a third interconnecting opening (76).
