Definitions
- FIG1 is a schematic structural diagram of a double-sided cooling battery module provided by the present application.
- FIG4 is a cross-sectional schematic diagram of a serpentine tube provided in the present application.
- two liquid inlet pipes 20 and two liquid outlet pipes 30 are provided, and the liquid inlet ends located on the same side are connected to the same liquid inlet pipe 20, and the liquid outlet ends located on the same side are connected to the same liquid outlet pipe 30.
- This arrangement reduces the number of serpentine tubes 10 connected in parallel with the liquid inlet pipe 20 and the liquid outlet pipe 30 on a single side to half of the total number of serpentine tubes 10, and the number of serpentine tubes 10 that divide the flow is smaller, making it easier to achieve flow balance between the serpentine tubes 10.
- the liquid inlet pipe 20 and/or the liquid outlet pipe 30 are configured as bellows, and the corrugated sections of the bellows are arranged between the adjacent serpentine tubes 10 connected thereto.
- the liquid inlet pipe 20 and the liquid outlet pipe 30 are both configured as bellows, and the bellows include a plurality of corrugated sections arranged at intervals, and joints 4 are connected between the corrugated sections.
- the configuration of the bellows can compensate for design and assembly tolerances and improve the stability of the structure.

Abstract
La présente invention concerne un module de batterie à refroidissement double face, comprenant un système de refroidissement liquide, et une pluralité de cellules cylindriques situées dans le système de refroidissement liquide. Le système de refroidissement liquide comprend : une pluralité de tubes en serpentin disposés côte à côte et espacés les uns des autres, les tubes en serpentin venant en butée et en ajustement contre les faces périphériques des cellules cylindriques sur deux côtés de celles-ci, chaque tube en serpentin étant pourvu à l'intérieur d'un canal d'écoulement de retour ayant deux extrémités situées à la même extrémité du tube en serpentin dans la direction de la longueur, et une extrémité d'admission de liquide et une extrémité d'évacuation de liquide du tube en serpentin étant situées aux deux extrémités du canal d'écoulement de retour ; et un tuyau d'admission de liquide raccordé aux extrémités d'admission de liquide, et un tuyau d'évacuation de liquide raccordé aux extrémités d'évacuation de liquide.
