Among them, a DC water-cooled power supply is a power supply that integrates a cooling system and control technology. It effectively manages the heat generated by the power supply through a liquid cooling system to ensure that the power supply maintains stable performance during high-power operation. Compared with traditional air-cooled power supplies, DC water-cooled power supplies have the advantages of good heat dissipation, low noise, and environmentally friendly heat dissipation process.
