A liquid-immersed cooling module according to an embodiment of the present disclosure may include: a housing containing
cooling fluid at a predetermined
water level; at least one
unit housing housed inside the housing in a manner submerged in the
cooling fluid, and forming flow channels for the
cooling fluid to flow in and out of the
unit housing, housing a battery module inside and being open at the top; and a condenser configured to liquefy the gas formed by the
vaporization of the cooling fluid in the housing and reintroduce it into the housing in a
liquid state, wherein the two sides of the battery module are spaced apart from the opposite inner sides of the
unit housing to form flow channels for the cooling fluid, including porous
moisture-absorbing components combined with the opposite sides of the battery module. The liquid-immersed cooling module of the present disclosure improves the efficiency and reliability of liquid-immersed cooling of the battery module, effectively reducing the
power consumption of the entire device and achieving the effect of reducing carbon emissions.
