A tank is provided which can store, while cooling, drinks or other liquids, such as milk, having a storage temperature close to 0.degree. C. or below. A cooling tank ( 1 ) can be mounted on a truck or the like for transportation, while storing and cooling milk. It is characterized in that brine (antifreeze solution) which has a freezing point below 0.degree. C. is cooled in a cooling unit ( 34 ) and allowed to pass, without stagnation, along fluid passages in flow guide members ( 14, 18 ) installed on the wall surface of the tank body ( 10 ). The cooling unit ( 34 ) preferably has an evaporator in a heat pump type refrigerator ( 30 ) for example, which uses a refrigerant for cooling the brine. Since the brine with a freezing point below 0.degree. C. is used, a large-sized water tank for cooling becomes unnecessary, and further since the brine will flow without stagnation, the liquid inside the tank body can be effectively cooled.
