Description

Cooling system for edge terminal network equipment

Technical Field

The application relates to the field of equipment cooling, in particular to a cooling system of edge-end network equipment.

Background

In the related art, an air-cooled cooling method is generally adopted for cooling servers in a machine room. However, in large data centers, air cooling alone has not been sufficient to meet the heat dissipation requirements of high heat flux servers.

The liquid cooling mode is to contact liquid with a heating component, so that heat of the server is taken away through heat exchange. Compared with the traditional air cooling mode, the heat quantity leading-out mode of the liquid cooling mode is different. The liquid has the characteristics of high conduction efficiency, high specific heat capacity and the like, can realize high-efficiency refrigeration of IT (Internet Technology ) equipment, realizes high-efficiency energy conservation of a data center, and simultaneously improves the reliability of devices.

Currently, liquid-cooled servers are mainly deployed in the field of data centers. The liquid cooling system of the whole data center is divided into three parts: evaporation end, heat exchange unit, outdoor radiating unit. At the evaporation end, the heat of each server is brought to the heat exchange unit through the liquid cooling plate or the refrigerant in the immersed liquid cooling; the heat exchange unit exchanges the heat of the internal circulating backwater to external circulating water through the heat exchanger, the temperature of the internal circulating water is reduced, meanwhile, the temperature of the external circulating water is increased, and the heat is carried out through the external circulating backwater; and an outdoor heat dissipation unit (e.g., an outdoor cooling tower) for dissipating heat in the externally circulated return water to the air through the cooling tower.

As edge computing evolves, more and more edge-side servers have cooling requirements. If a common air cooling mode is adopted, the requirements of dust prevention, water prevention, corrosion prevention, electromagnetic ionizing radiation prevention and the like are often difficult to meet; if a liquid cooling mode is adopted, the liquid cooling system applied to the data center aims at the server cluster, the occupied space is large, generally dozens or even hundreds of square meters, and the area of a machine room is small in the edge end application environment, so that the deployment requirement cannot be met.
