- the cooling structure 20 is made of a Zn-based plated steel sheet.
- a Zn-based plated steel sheet has high external corrosion resistance and coolant corrosion resistance. Therefore, the cooling structure 20 has high external corrosion resistance and coolant corrosion resistance.

- the above ratio is more preferably 0.23 to 0.71 from the viewpoint of the balance between bonding strength and cooling efficiency. That is, the cooling performance of the cooling structure 20 improves as the above ratio increases, but it is preferable to consider the bonding strength with the battery pack 10 as well. From this point of view, the above ratio is preferably 0.23 to 0.71.
- the distance h in the thickness direction of the battery unit 1 is not particularly limited, but from the viewpoint of the cooling efficiency of the battery pack 10, it is preferably about 0.9 to 25.0 mm.

(0.強度の評価)
作製したZn系めっき鋼板等の強度をJIS Z 2241の規定に準拠した引張試験によって評価した。この結果、Zn系めっき鋼板等の強度はいずれも270MPa以上であった。ついで、Zn系めっき鋼板等と同程度の厚さを有するAl板(A6063)を準備し、このAl板の強度を上記と同様の方法で評価したところ、200MPa以下であった。したがって、Zn系めっき鋼板等が高い強度を有することが確認できた。
作製したZn系めっき鋼板等をバッテリーユニットの冷却構造(冷却装置)に用いた時の耐冷却液性を調査した。具体的には、作製したZn系めっき鋼板等をエリクセン加工することで、Φ50mm、絞り高さ40mmのカップ形状の円筒加工品を作製した。この円筒加工品の内側に冷却液を30mL加えたのち、蓋をして密閉した。冷却液には、日産自動車社のロングライフクーラント液を水で30質量%に希釈した水溶液を用いた。これらを90℃の恒温槽に1000時間静置し、冷却液浸漬部の鋼板の劣化を促進させた。また、クーラント液が劣化した場合を想定して、当該ロングライフクーラント液の30質量%水溶液中に蟻酸を800ppm添加した劣化液を用いた同様の試験もおこなった。試験後、円筒加工品に浸漬した冷却液を取り除き、円筒加工品を乾燥させたのちに、冷却液浸漬部の腐食状況を観察し、次に示す基準で耐冷却液性を評価した。結果を表5A~5Eに示す。
5点:外観変化なし
4点:黒色に変色している、もしくは点状の白錆が発生している。
3点:白錆が発生しているが冷却液浸漬部の白錆発生面積が冷却液浸漬部の総面積に対して20%未満である。
2点:白錆発生率が20%以上80%未満である。
1点:白錆発生率が80%以上である、もしくは赤錆が発生している。
バッテリーユニット(冷却構造含む)が外気に触れる部分での耐食性評価として耐食性試験を実施した。外気に触れる部位には、電着塗装を施すことが一般的であるため、本発明においては電着塗装後の耐食性を評価した。
5点:カット部からの塗膜膨れ幅が15mm以内で、赤錆発生無しの場合
4点:カット部からの塗膜膨れ幅が15mm超、20mm以内で、赤錆発生無しの場合
3点:カット部からの塗膜膨れ幅が20mm超で、赤錆発生無しの場合
2点:カット部から赤錆が僅かに発生していた場合
1点:カット部全面から赤錆が発生していた場合
(1.バッテリーユニットの作成)
作製したZn系めっき鋼板等を用いて図3に記載のバッテリーユニット1を作製した。具体的には、切断加工のみの平板材をケース上蓋(上面部10c)及び流路上蓋26とした。これとは別に用意したZn系めっき鋼板等をプレス機によって角筒深絞り加工し、加工後にフランジ部分を切断することでバッテリーパック10の他の部分(底面部10a及び側面部10b)を作製した。また、バッテリーパック10の底面部10aが巾315mm×長さ2000mmとなるよう加工した。加工時には防錆油をZn系めっき鋼板等に塗布し、加工後にアルカリ脱脂によって油を除去した。角筒形状のポンチ肩R、ダイス肩R、コーナーRは全て20mmとした。冷却構造20もプレス加工によって作製した。冷却構造20における各Rは10mmとし、流路本数、流路幅、及び流路間距離が表4に示す値となるように作製した。
作製したバッテリーユニット1のラバーヒーターに電流を流してバッテリーユニット1を加熱した。ここで、ラバーヒーターの表面温度が50℃となる電流値を事前に探索しておき、その電流値を固定値としてラバーヒーターに流した。ついで、水冷媒体用流路25に冷却液を流した。冷却液は、PITWORK社のロングライフクーラント液を水で30質量%に希釈した水溶液を用いた。また、冷却構造20の両側の流路端にホース、ポンプ、及びチラーを取り付けて循環経路を構成し、この循環経路内で冷却液を循環させた。ここで、冷却水の温度が25~30℃となるようにチラーを制御した。そして、冷却水循環開始から1時間後の冷却流路間の中間部分直上のケース内ラバーヒーター表面の温度を測定し、温度が冷却水を循環させていない状態の時より8℃以上低くなっていた場合を◎、温度低下が8℃未満5℃以上であった場合を〇、5℃未満2℃以上を△、2℃未満を×と評価した。なお、バッテリーユニット1の冷却特性評価試験は、空調にて25℃に保たれた室内で行った。結果を表5A~5Eに示す。
