Description

Technical Field

[0001] The present application relates to the technical field of heat exchangers, and in particular to dual-medium heat exchange devices, servers and data centers. Background Art

[0002] Traditional data center cooling relies on artificial refrigerant preparation, resulting in a large amount of electricity consumption. my country is rich in marine resources, and the seabed water temperature is generally 15-20℃, which can be used as a source of natural cold source for data centers with great potential. Building an efficient seabed data cabin has also become one of the development directions of green data centers. The heat dissipation types of data centers mainly include air cooling and liquid cooling. Liquid cooling has the advantages of high heat transfer efficiency, low transmission energy consumption, and compact heat exchange structure. However, the current traditional liquid-liquid heat exchanger design is an equal flow channel structure.
