1. A closed-loop cooling device for batteries, comprising:
a battery module; a blower fan sucking gas present inside the battery module and discharging the gas through an exhaust port; a loop duct connected to the exhaust port at one end thereof and an intake port at another end thereof so as to deliver the gas discharged through the exhaust port; an inlet duct including the intake port and connected to the battery module to introduce the gas into the battery module; a housing covering the battery module, the exhaust port, the blower fan, the intake port, and the inlet duct, and a portion of the loop duct and sealed to prevent outer air from being introduced thereinto; a heat exchanger disposed in the loop duct to cool the gas; and a pipe connected to the heat exchanger and through which a cooling fluid flows to cool the heat exchanger, wherein the loop duct has an inner portion which is disposed in the housing and a protruding portion which is protruded outside the housing, the heat exchanger is disposed in the protruding portion of the loop duct to form moisture generated due to the heat exchanger outside the housing, a boundary between the housing and the protruding portion of the loop duct is sealed. |
