Cooling system

The invention relates to a cooling system (1) for a battery of an electric or hybrid vehicle (10), comprising a cooling device (12) and a thermal interface (11), and characterized in that: the cooling device (12) generates a movement of a cooling fluid in a cooling direction (13) between an inlet point (121) and an outlet point (122); -the thermal interface (11) has: a first surface (111) which is at least substantially in contact with the cooling means; and a second surface (112), referred to as a heat exchange surface, opposite the first surface, intended to be placed in contact with or close to the battery; and-the size of the heat exchange surface (112) in a secondary direction (14) perpendicular to the cooling direction (13) of the cooling system increases in the cooling direction (13). 本发明涉及一种用于电动车辆或混合动力车辆(10)的电池的冷却系统(1)，所述冷却系统包括冷却装置(12)和热界面(11)，并且其特征在于：-冷却装置(12)产生冷却流体沿冷却方向(13)在入口点(121)与出口点(122)之间的运动；-热界面(11)具有：第一表面(111)，该第一表面至少基本上与冷却装置接触；和第二表面(112)，该第二表面称为热交换表面、与第一表面相反、旨在放置成接触或靠近电池；以及-所述热交换表面(112)在垂直于冷
