Refrigerating device, system, method, medium and equipment with dynamically adjustable wind-liquid ratio Technical Field The invention relates to the technical field of infrastructure and IT support, in particular to a refrigerating device, a refrigerating system, a refrigerating method, a refrigerating medium and refrigerating equipment with a dynamically adjustable wind-liquid ratio. Background With the rapid development of artificial intelligence, cloud computing and other technologies, computing centers face increasing demands for heat dissipation with high heat flux density. The cold plate type liquid cooling technology has become one of the main stream cooling technology routes of the data center due to the higher technical maturity. According to the technology, liquid is used as a heat transfer working medium and flows through the inside of a cold plate of a server to take away heat generated by high heat flux density components such as a CPU (Central processing Unit), a GPU (graphics processing Unit) and the like, and other low power density components in the server still rely on air cooling for heat dissipation, so that an air-liquid fusion refrigeration architecture is formed. In this architecture, dynamic adjustment of the air-to-liquid ratio (i.e., the ratio of air cooling to liquid cooling heat dissipation) is critical to achieving efficient, adaptive cooling. However, the data center infrastructure is usually built in advance of the business, and it is difficult to accurately estimate the actual wind-liquid ratio requirement in the design stage, and in the subsequent operation, the dynamic change of the power consumption of the server, the equipment update and the fluctuation of the outdoor environment condition all cause the continuous change of the duty ratio of the wind cooling load and the liquid cooling load. Two schemes are proposed in the related art, wherein the first scheme is a wind-liquid independent loop system, and the problems of large design capacity of a cold source and high initial investment cost exist although the proportion is adjustable. The second type is a scheme of supplementing cooling to the air cooling side by adopting a fluorine system, although the scheme can adjust the air-liquid ratio to a certain extent, the adjusting range is limited, and the scheme is mainly suitable for scenes with high air cooling load and is difficult to meet the requirement of large-range dynamic change of the air-liquid ratio. In summary, the related technologies have limitations, and the wide-range and high-flexibility dynamic adjustment of the wind-liquid ratio cannot be realized on the premise of considering the cost and the energy efficiency.
