Abstract
A power conversion device includes a casing, a middle plate and a converter module. The casing includes a base plate. The base plate has a concave recess therein. The base plate forms a base plate convex hull at a side opposite to the concave recess. The middle plate has a middle plate groove therein. The middle plate groove corresponds to the base plate convex hull. The middle plate and the base plate combine up, such that the base plate convex hull fluidly seals the middle plate groove, making the middle plate groove to form a first coolant channel. The converter module is at least partially located in the concave recess.
Claims19
A power conversion device, comprising:
- a casing comprising a base plate and a side wall, the base plate having a concave recess therein, the base plate forming a base plate convex hull at a side opposite to the concave recess, the side wall surrounding the base plate;
- a middle plate having a middle plate groove therein, the middle plate groove corresponding to the base plate convex hull, the middle plate and the base plate combining up, such that the base plate convex hull fluidly seals the middle plate groove, making the middle plate groove form a first coolant channel, the middle plate forming a middle plate convex hull at a side opposite to the middle pate groove, the middle plate convex hull and the side wall forming an accommodation space in between;
- a converter module at least partially located in the concave recess;
- and
- at least one fixing piece fastening together the middle plate and the base plate and being at least partially located in the accommodation space.
