POWER CONVERSION DEVICE

摘要

A power conversion device includes a casing, an isolation wall, a first circuit board unit, a converter module, a coolant channel base plate, a circuit board plate and a top cover. The casing includes a base plate which has a base surface and a recessed space. The isolation wall partitions the recessed space into a circuit board accommodation space and a coolant channel. The isolation wall has a circuit board subsidiary wall and a coolant channel subsidiary wall. The circuit board subsidiary wall and the coolant channel subsidiary wall have a height difference. The first circuit board unit is located in the circuit board accommodation space. The converter module is located opposite to the recessed space. The coolant channel base plate fluidly seals the coolant channel. The circuit board base plate seals the first circuit board unit. The top cover seals the converter module.
