Battery module cooling fins and footings system and method

摘要

The present disclosure includes a battery module having a housing with a wall that includes an aperture in the wall. The battery module also includes an electrochemical cell having a terminal end and a base end opposite the terminal end. The electrochemical cell is disposed within the housing such that the base end is positioned proximate to the aperture of the wall. Further, a heat sink of the battery module is engaged with the aperture and includes cooling fins extending outwardly from the heat sink a first distance from an external surface of the wall. The battery module also includes feet of the housing extending outwardly from the wall a second distance from the external surface of the wall. The second distance is greater than the first distance.

主权项

1. A battery module, comprising:
a housing having a wall with an aperture; an electrochemical cell having a terminal end and a base end opposite the terminal end, wherein the electrochemical cell is disposed within the housing such that the base end is positioned proximate to the aperture of the wall; a heat sink disposed in the aperture and having cooling fins extending outwardly from the heat sink in a first direction and along the heat sink in a second direction transverse to the first direction; and feet of the housing extending outwardly from an external surface of the wall in the first direction and along the wall in the second direction, wherein the feet and the cooling fins are offset with respect to each other along the second direction, wherein each pair of adjacent feet defines a channel between the adjacent feet of the pair, and wherein the feet and the cooling fins are staggered with respect to each other in a third direction transverse to the first and second directions such that each cooling fin is aligned with a corresponding one of the channels defined by one of the pair of adjacent feet.
