US Patent 8960346 Battery cooling structure of hybrid industrial vehicle

An object of the present invention is to provide a battery cooling structure of a hybrid industrial vehicle such as a hybrid forklift, the battery cooling structure being capable of sufficiently cooling a battery and also of eliminating the possibility that the battery receives heat from its peripheral devices. To achieve the object, a second cooling air flow passage (35) for battery is provided separately from a first cooling air flow passage (31) in which a radiator (32) is disposed. A battery pack 26 or a battery is disposed in the second cooling air flow passage (35). The second cooling air flow passage (35) is connected to the first cooling air flow passage (31) at a position upstream of a cooling fan (33) disposed in the first cooling air flow passage (31), so that the cooling fan (33) sucks cooling air in the first cooling air flow passage (31) and also sucks cooling air in the second cooling air flow passage (35).
