Un système de refroidissement (10) comprend : une pluralité de refroidisseurs (30, 31, 32, 33) ; et un canal d'écoulement d'alimentation en fluide frigorigène (W20). Les refroidisseurs ont des parties d'échange de chaleur (300, 310, 320, 330) qui refroidissent une batterie (20) par échange de chaleur entre la batterie et un fluide frigorigène s'écoulant à l'intérieur. Le canal d'écoulement d'alimentation en fluide frigorigène a formé à l'intérieur : un canal d'écoulement principal (W21) à travers lequel s'écoule le fluide frigorigène ; et une pluralité de canaux d'écoulement ramifiés (W22a, W22b, W22c, W22d) qui se ramifient à partir du canal d'écoulement principal de façon à distribuer le fluide frigorigène aux refroidisseurs respectifs. Le fluide frigorigène est fourni aux refroidisseurs en parallèle. Lorsqu'une partie où les canaux d'écoulement ramifiés se ramifient depuis le canal principal dans le canal d'écoulement d'alimentation en fluide frigorigène est définie comme une partie de ramification (Pb), des parties d'étranglement (301, 311, 321, 331) sont disposées sur des parties entre la partie de ramification et les parties d'échange de chaleur respectives.
