    摘要: Provided is a construction machine capable of smooth exhaust and suppression of a leak of noise from an engine room (31), including an engine guard (23) defining an engine room (31), a cooling fan (33) disposed in the engine room (31), a projection element (36) projecting upward beyond the engine guard (23), and an exhaust duct (38). The exhaust duct (38) has a bent shape including a first duct section (38a) extending along an axial flow direction of the cooling fan (33) from an upstream end portion surrounding a duct inlet (38c) to a connection portion and a second duct section (38b) extending upward from the connection portion and surrounding a duct outlet (38d) opened upward, also including an engine concealment section obstructing a direct view to an engine (32) through the duct outlet (38d) from outside the engine room (31).

    摘要: A liquid-air cooling system (1) has at least one fan device (2) that consists of at least one variable-speed fan motor (3) driving a fan impeller (4) to create a cooling power for a fluid (5) in a fluid cycle (6). In order to regulate the speed of the fan motor (3) by means of a control and/or regulation device (24), at least one actual value (t
    ist ) downstream of the segmented heat exchanger (19) is compared to a predefined desired value (t
    soll ), and the control and/or regulation device (24) adjusts the cooling power according to the current power values of the respective machine unit (9).

    摘要: A cooling system for a compact vehicle such as a compact loader (10) having an engine (18) and an engine compartment (16), includes a single axial flow fan (46) that is surrounded by a shroud (40) and has a high pressure side (44) and a low pressure side (42). Air flow generated by the fan (46) is used for cooling components (58, 60) of the compact vehicle (10) and exhausting heated air from a second shroud. Auxiliary openings (82) are provided between the engine compartment and the shrouds to provide air flow between the engine compartment (16) and one or both of the shrouds (40, 62) when the fan (46) is rotating. The motor (52) driving the fan (46) is reversible.
