REFRIGERANT PASSAGE FORMATION STRUCTURE BETWEEN BATTERY CASES

摘要

PROBLEM TO BE SOLVED: To provide a refrigerant passage formation structure between battery cases, advantageous in cost as compared with conventional ones.SOLUTION: (1) A refrigerant passage formation structure 10 between battery cases includes: two battery cases 21 and 22 adjacent with each other among a plurality of layered square metallic battery cases 20; and a refrigerant passage formation member 30 provided between the two battery cases 21 and 22 and forming a refrigerant passage P between the two battery cases 21 and 22. The refrigerant passage formation member 30 is formed as a separate body from the two battery cases 21 and 22, and fixed to a first battery case 21 of one of the two battery cases 21 and 22.
