The present invention relates to an air-cooling-based sealed battery pack structure. The present invention comprises: a battery module assembly (BMA) (10) comprising a plurality of battery cells (11); a primary sealing housing (20a) of which an upper object and a lower object are formed as a hexahedral shape having an open upper side and which is formed for primary sealing of the plurality of battery cells (11) which come in contact with a primary heat sink (20) and a secondary cold sink (30); a secondary sealing housing (30a) of which an upper object and a lower object are formed as a hexahedral shape having an open upper side and covering the outer peripheral sides of the primary sealing housing (20a) and which is formed for secondary sealing of the plurality of battery cells (11) which come in contact with the primary heat sink (20) and the secondary cold sink (30); and a Peltier element (50) which is inserted into an insertion groove (62) inside a cooling fin housing (61) having formed first cooling fins (60) on the lower side thereof, of which the upper part comes in contact with the secondary cold sink (30) through a cold block for cooling concentration (40), and which is formed inside a structure sealed by means of the secondary sealing housing (30a) and the cooling fin housing (61). |
