Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled cabinet technology, specifically to a liquid-cooled cabinet. Background Technology

[0002] In the electrical industry, to cope with the heat generated during the operation of intelligent devices, electronic components, and some mechanical structures, cooling systems are usually installed in the cabinet to dissipate excess heat in real time, so as to avoid heat accumulation inside the cabinet, which would affect the smooth operation of the equipment and the safety of production operations.

[0003] Liquid-cooled cabinets replace traditional air cooling with liquid cooling, which can significantly reduce the energy consumption of the cooling system. Compared with air-cooled cabinets, liquid-cooled cabinets can reduce power consumption by about 40%. In addition, the efficiency of using coolant to remove heat is much greater than that of air cooling, making it more suitable for scenarios that require efficient heat dissipation, such as server cooling. Furthermore, liquid cooling systems usually require fewer fans, which can effectively reduce noise pollution compared to air cooling solutions.

[0004] Liquid-cooled cabinets typically include a cooling tank, an inlet pipe, and an outlet pipe. The inlet pipe supplies coolant to the cooling tank, while the outlet pipe extracts coolant from the cooling tank, thus circulating the low-temperature coolant back into the cooling tank to continuously cool the equipment (such as servers) inside. However, in existing liquid-cooled cabinets, the entire fluid flow field is usually quite turbulent during the process from the inlet pipe into the cooling tank to the outlet pipe, resulting in low cooling efficiency.

[0005] Therefore, how to improve the cooling efficiency of liquid-cooled cabinets has become a technical problem that urgently needs to be solved in this field. Utility Model Content
