Patent ID: 7818972

Claim:
A water removal apparatus for removing water contained in a coolant circulating through a target object, the apparatus comprising: a circulation line through which the coolant circulates through the target object; a pump disposed in the circulation line which circulates the coolant through the target object; a bypass line through which a part of the coolant separated from the circulation line flows; a cooling system, having a separate cooling circuit, which cools the coolant by heat transfer with a refrigerant circulating the cooling system through a first heat exchanger provided in the circulation line; a second heat exchanger, provided in the bypass line, which heats the coolant flowing along the bypass line by using a waste heat of the cooling system; and a water adsorption material, disposed in the bypass line and provided at a downstream side of the second heat exchanger, which adsorbs the water contained in the coolant heated by the second heat exchanger.
