Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/029008
Kind Code:
A1
Abstract:
An electronic control device (1) comprises: a housing (2) in which a circuit board (6) is sealed and accommodated; a first heat dissipation fin (21a) provided to the lower surface of the housing (2); a second heat dissipation fin (22a) provided to the upper surface of the housing (2); an air duct (4) that is attached to the outside of the housing (2) so as to cover the first heat dissipation fin (21a) and the second heat dissipation fin (22a) and forms a cooling air flow path through which cooling air flows on the upper surface side and the lower surface side of the housing (2); and a cooling fan (8) that is installed on a downstream side of the heat dissipation fins (21a, 22a) positioned on the downstream side of the cooling air flow path in the first heat dissipation fin (21a) and the second heat dissipation fin (22a) and evacuates the cooling air toward the downstream side of the cooling air flow path. The cooling air flow path is formed from a single flow path that does not branch in a part leading from the first heat dissipation fin (21a) to the second heat dissipation fin (22a).
