Description

Technical Field

[0001] This invention belongs to the field of data center equipment heat dissipation technology, and relates to a one-compartment air-liquid cooling system for data centers. Background Technology

[0002] With the rapid development of social informatization, data center construction has shifted from IDC (Internet Data Center) to AIDC (AI Data Center) solutions. The power consumption per rack has surged from 10kW to 20kW, especially for high-density heat dissipation chips in high-performance AI (AI) and ChatGPT (ChatGPT) GPUs, where single-rack power consumption can reach over 100kW. This increased demand for single-rack power has spurred the rapid development of liquid cooling technology in data centers. Cold plate liquid cooling and single-phase immersion liquid cooling are the mainstream cooling technologies for high heat flux density equipment. Currently, cold plate liquid cooling is an indirect liquid cooling technology, capable of dissipating only 70%-90% of a server's power consumption, often requiring supplementary air cooling technologies. Single-phase immersion liquid cooling is a direct contact liquid cooling technology, capable of dissipating 100% of a server's power consumption; however, in high summer temperatures, the indoor ambient temperature still remains around 40 degrees Celsius, necessitating additional air cooling technologies for routine maintenance. Commonly used data center cooling systems combining liquid cooling and air cooling typically employ a combination of liquid cooling and room air conditioning. This type of cooling system has high requirements for the data center's construction environment, is not conducive to the rapid deployment of high-density computing servers, and cannot fully utilize outdoor natural cold sources, which greatly limits the promotion and application of high-density computing scenarios. There is an urgent need to optimize the air-liquid cooling system for data centers in order to rapidly replicate and promote high-density computing data centers. Summary of the Invention

[0003] Based on the current development status of data center cooling systems, this invention proposes an energy-saving air-liquid integrated cooling system for data centers. It optimizes the design of cold-plate liquid cooling, single-phase immersion liquid cooling, and heat pipe air conditioning using a containerized approach, dividing the system into two parts: an internal container and an external container. The liquid cooling and air cooling systems, serving as the heat dissipation and cooling system for high-density computing servers, are placed inside the container. The photovoltaic controller, battery, and inverter, serving as the green power supply system, are also placed inside the container. The multi-unit air-cooled module, serving as the cold source system, is placed on the top of the container, and the solar photovoltaic panels, also serving as the green power supply system, are placed on the top of the container, forming the air-liquid integrated cooling system for data centers. The heat pipe air conditioning system fully utilizes natural cold sources during low-temperature seasons, the evaporative cooling module fully utilizes natural cold sources during dry seasons, and the solar energy storage system serves as the green power supply system. This air-liquid integrated cooling system can be flexibly deployed in any environment, fully utilizing outdoor natural cold sources, thereby reducing the construction difficulty of high-density computing server edge deployment, optimizing the construction process, and lowering the operation and maintenance costs of the air-liquid integrated cooling system.
