Abstract
A power-module assembly includes plates defining pockets and arranged in a stack such that the pockets cooperate to define coolant chambers interleaved with the plates. The assembly further includes cards having a power module encased in a frame. The frame has an outward projecting spacer, and each card is disposed in a corresponding one of the chambers with the spacer contacting a wall of the corresponding chamber to form a coolant passage between the wall and the card.
Claims19
A power-module assembly comprising:
- plates, each defining pockets, arranged in a stack such that the pockets cooperate to define coolant chambers interleaved with the plates;
- and
- cards including a power module encased in a frame having an outward projecting spacer, wherein each card is disposed in a corresponding one of the chambers with the spacer contacting a wall of the corresponding chamber to form a coolant passage between the wall and the card.
A power-module assembly comprising:
- plates each including first and second opposing major sides, a first pocket recessed into the first major side, a second pocket recessed into the second major side, and a dividing wall having a first surface that forms a floor of the first pocket and a second surface that forms a floor of the second pocket, wherein the plates are arranged in a linear stack such that adjacent ones of the first and second pockets cooperate to define coolant chambers interleaved with the dividing walls;
- and
- cards, each having opposing first and second major faces and including a power module encased in a frame that has a spacer extending from the second major face, wherein each of the cards is disposed in one of the coolant chambers with the spacer attached to a corresponding one of the dividing walls to support the card within the coolant chamber such that a first coolant passage is formed between the second major face of the card and the corresponding dividing wall and a second coolant passage is formed between the first major face of the card and another corresponding one of the dividing walls.
A power-module assembly comprising:
- stacked plates including adjacent first and second plates defining a first pocket and a second pocket, respectively, cooperating to form a coolant chamber, wherein the first and second plates are secured together by a connection feature that includes a projection portion extending from the first plate and a receptacle portion defined in the second plate and configured to receive the projection portion;
- and
- a first card positioned in the coolant chamber such that a first coolant passage is defined between the first plate and the first card and a second coolant passage is defined between the second plate and the first card.
