To provide a cooling unit in which the warpage of a duct partition can be suppressed.SOLUTION: A cooling unit includes a member to be cooled and a duct. The member to be cooled has a plurality of cooling fins. The duct is fixed to the member to be cooled, has a partition facing a plurality of the cooling fins, and flows gas into a space between the partition and a plurality of the cooling fins. The partition has a rib that projects on the outer surface of the partition, the rib bending such that a recess is formed on the inner surface of the partition. The depth of the recess is equal to or less than 1/2 the thickness of the partition.SELECTED DRAWING: Figure 2

    【課題】 ダクトの隔壁の反りを抑制する。【解決手段】 冷却ユニットであって、被冷却部材とダクトを有する。前記被冷却部材は、複数の冷却フィンを有する。前記ダクトは、前記被冷却部材に固定されており、複数の前記冷却フィンに対向する隔壁を有し、前記隔壁と複数の前記冷却フィンの間の空間に気体を流す。前記隔壁が、前記隔壁の外側表面に突出し、前記隔壁の内側表面に凹部が形成されるように屈曲するリブを有している。前記凹部の深さが前記隔壁の厚みの1/2以下である。【選択図】図2
