For the cabinet equipment used in warships, an environmental test that satisfies the MIL-STD-810G standard must be performed. In high-temperature operating tests, thermal design is an important factor because cabinet equipment is operated at high ambient temperatures. In this environment, water cooling is used to ensure the heat dissipation stability of the equipment. In water cooling, cooling water is supplied to the heat exchanger from the outside, and heat from the air inside the equipment is released through the cooling water. In this study, a process for predicting the thermal performance of water-cooled cabinets is established through numerical analysis. The performance of a heat exchanger is predicted using a computational fluid dynamics method and verified experimentally. In addition, the effectiveness changes of a fin-tube heat exchanger with a single pipe are studied based on the direction and flow rate of the cooling water. Using the calculated effectiveness of the heat exchanger, the operating environment of the rack equipment inside the water-cooled cabinet is predicted.
