Diode module mounting structure for on-board charger in battery-powered industrial vehicles

摘要

(57) [Abstract] OBJECTIVE without using a cooling plate dedicated diode module charger is intended to allow dissipating the heat generated for the diode modules. [Configuration] contact the one surface of the body frame 1 inside surface the cooling plate 2 equivalents, the control device 3 is fixed through the cooling plate 2. Power element 4 consisting thyristors and diodes of the control device 3 is mounted on the other surface of the cooling plate 2. The central portion of the body frame 1 in contact with one surface of the cooling plate 2 has holes 6 for the diode module 7 mounted is opened, one surface of the cooling plate 2 through the hole 6 There are exposed. As the exposed surface of the cooling plate 2 of the charger diode module 7 is a vehicle body frame 1 It has attached through the opening 6 from the outside.
