FIELD: cooling.
SUBSTANCE: invention relates to the cooling system for multielement storage battery. Storage battery comprises a set of prismatic battery elements, the first and the second cooling medium headers and a set of corrugated flow plates, alternating with the battery elements, where every flow plate extends from the first header to the second header and provides multiple flow channels for transfer of medium from the first header to the second header, each plate of the set of corrugated flow plates is an extruded plastic structure which comprises the first and the second sheets impermeable for medium, and multiple parallel ribs arranged between the sheets and connecting the first and the second sheets, and said multiple ribs form multiple flow channels.
EFFECT: technical result is higher efficiency of cooling the elements of multielement lithium-ion accumulator by reduction of thermal gradient among the elements.
