Abstract: In this battery heat exchange structure, a heat exchange panel 42 and a battery cell 41 are closely arranged side by side so that a heat exchange wall 421 of the heat exchange panel 42 in which a heat exchange fluid circulates follows a side surface 411 of the battery cell 41, and the heat exchange wall 421 following the side surface 411 of the battery cell 41 is formed of a flexible thin plate. Preferably, a flow path wall 425 defining a flow path through which the heat exchange fluid circulates along the heat exchange wall 421 is provided in the heat exchange panel 42 so as to be able to expand and contract in an erecting direction. This battery heat exchange structure can perform heat exchange between the heat exchange panel and the battery cell with high efficiency and stably maintain high heat exchange efficiency even when the battery cell expands.

Abstract: A first sheet metal is provided with slits. Elastic pieces having flat shapes are each formed between the slits adjacent to each other, and both ends of each of the elastic pieces are connected with both ends of an adjacent one of the elastic pieces. A second sheet metal is provided with protrusions each of which is protruded toward a corresponding one of the elastic pieces.
