To suppress battery degradation due to heating under a circumstance where refrigerant has a degree of superheat in a tube downstream of a refrigerant flow path of a cooling module. A cooling module (20) for cooling a battery (10) is provided with: a first header (22) including a refrigerant inflow portion (221) into which a refrigerant for exchanging heat with a battery flows, and a refrigerant outflow portion (222) from which the refrigerant that has exchanged heat with the battery flows out; a second header (24); and a plurality of tubes (26) arranged between the first header and the second header to perform heat exchange with the battery. The plurality of tubes comprise one or more first tubes (26A) for flowing the refrigerant from the first header toward the second header, and one or more second tubes (26B) for flowing the refrigerant from the second header toward the first header. A total of surfaces of the first tubes for heat exchange with the battery is greater than a total of surfaces of the second tubes for heat exchange with the battery.
即使在冷却模组的冷媒流路的下游侧的管路内冷媒具有过热度的状况下,也能够抑制由发热引起的电池的劣化。对电池(10)进行冷却的冷却模组(20)具备第一集管(22)、第二集管(24)和多个管路(26),该第一集管(22)具有供与电池进行热交换的冷媒流入的冷媒流入部(221)和供与电池进行了热交换的冷媒流出的冷媒流出部(222),该多个管路(26)配置在第一集管与第二集管之间,用于在与电池之间进行热交换。多个管路由用于使冷媒从第一集管朝向第二集管流动的一个以上的第一管路(26A)和用于使冷媒从第二集管朝向第一集管流动的一个以上的第二管路(26B)构成,第一管路的与电池的热交换面的面积的总和大于第二管路的与电池的热交换面的面积的总和。
