Cooling structure and counter balanced forklift truck of the control device in the vehicle industry

摘要

PROBLEM TO BE SOLVED: To effectively cool a controller provided integrally with a cooling part in an electric circuit part.;SOLUTION: The electric circuit part 18 of a control unit 14 mounted inside a lower body part of a forklift is arranged inside the first cooling flow passage 30 formed by a body frame 27 and a left-side lower sidepanel 28, a cooling part 19 formed integrally in the electric circuit part 18 via a substrate 20 is arranged inside the second cooling flow passage 31 formed by the body frame 27. The electric circuit part 18 is directly cooled by the first air flow of cooling air introduced forcibly into the first cooling flow passage 30 from an outside of the body by an exhaust fan 35. The electric circuit part 18 is indirectly cooled also via the cooling part 19 directly cooled by the second air flow of cooling air introduced forcibly into the second cooling flow passage 31 from the outside of the body by a cooling fan 48.;COPYRIGHT: (C)2003,JPO
