CELL MODULE

摘要

A plurality of cells having a circular cross-section are arranged at a pitch D to form a cell row in a cell module, where D represents the cell diameter. A plurality of the cells are disposed in a close-packed arrangement in a cell-mounting space having a predetermined cooling surface, the arrangement pitch between adjacent cells being D, the cells being arranged along the direction perpendicular to the cooling surface, and adjacent cell rows being arranged at a pitch of (31/2) × (D/2) along the direction parallel to the cooling surface. A cell module in which a plurality of cells are accommodated in a metal cell case can be disposed on a cooling surface with a heat-conducting elastic body interposed therebetween.
