Abstract
A power conversion device includes a cooler, a terminal block and a case. The cooler defines an internal space through which a refrigerant flows. The terminal block covers a conducive part. The case accommodates the cooler and the terminal block therein. The case has an opening on its lateral wall portion for allowing connection between the conductive part of the terminal block inside the case and an external load disposed outside the case. At least a part of the terminal block is located closer to the opening than the cooler in a first direction to which an inner surface and an outer surface of the lateral wall portion of the case defining the opening are opposed, and is located between the cooler and an upper end of the opening in a second direction orthogonal to the first direction.
Claims4
A power conversion device comprising:
- a cooler defining an internal space therein to allow a refrigerant to flow;
- a terminal block covering a conductive part;
- and
- a case having a bottom portion and a lateral wall portion extending from the bottom portion, the bottom portion and the lateral wall portion defining a storage space of the case, and the case accommodating the cooler and the terminal block in the storage space, wherein
- the lateral wall portion is formed with an opening passing through the lateral wall portion from an inner surface facing the storage space to an outer surface opposite to the inner surface in a first direction for allowing connection between the conductive part accommodated in the storage space and an external load disposed outside of the storage space,
- the cooler is located further from the bottom portion than an upper end of the opening in a second direction orthogonal to the first direction in the storage space, the upper end of the opening being a furthest portion in the opening from the bottom portion in the second direction,
- at least a part of the terminal block is located closer to the opening than the cooler in the first direction, and is located between the upper end of the opening and the cooler in the second direction,
- the terminal block has an inclined facing surface that faces the cooler and is located between the upper end of the opening and the cooler,
- the inclined facing surface has a first end adjacent to the upper end of the opening and a second end further from the upper end of the opening than the first end in the second direction, and
- the inclined facing surface is inclined so that the second end is closer to the opening than the first end in the first direction.
