Description

Technical Field

[0001] The present invention relates to the field of refrigeration equipment, and in particular to a radiation condensation refrigerator for a computing power center. Background Art

[0002] Artificial intelligence (AI), an emerging technology that has garnered worldwide attention in recent years, is crucial as a core driver of economic and social development. By improving efficiency, promoting innovation, optimizing decision-making, and fostering social equity, AI is profoundly reshaping how we produce and live. However, the training and operation of AI technology requires the construction of vast computing centers.

[0003] The CPUs and GPUs in computing centers are composed of billions of transistors, and their PN junctions are subject to reverse leakage current. Currently, when the core operating temperature of a supercomputing GPU is 120°C, its reverse leakage current is 1,000 times higher than at room temperature. High operating temperatures significantly increase leakage current losses, increasing heat generation in the CPU and GPU, reducing the computing power of the computing center, increasing computing power consumption, and even causing CPU and GPU burnout.

[0004] Current air and liquid cooling technologies have cooling rates lower than the heat generation rate of computing equipment. The heat generated by the CPU and GPU of a computing equipment is transferred to the metal enclosure. The metal heat transfer bottom surface of the air and liquid cooling system is bonded to the surface of the metal enclosure with thermal adhesive. The microscopic mechanism of heat conduction in a conductor is that the transfer of kinetic energy within the conductor results in heat transfer. However, when the kinetic energy of the metal enclosure is transferred to the flexible thermal adhesive, it is significantly attenuated, significantly reducing the amount of heat that can be transferred to the liquid cooling chassis and air cooling radiator base. Therefore, neither air nor liquid cooling can solve the problem of cooling high-power CPUs and GPUs.

[0005] Furthermore, computing centers consume enormous amounts of electricity, which in turn generates significant heat. Currently, computing centers typically use cooling towers to evaporate water for heat exchange, which significantly consumes limited water resources. Furthermore, the location of a computing center requires sufficient and affordable water resources, which also places significant constraints on its location. Summary of the Invention

[0034] A radiation condensing refrigerator for a computing power center in this embodiment is configured, during specific implementation, to provide a plurality of evaporators 2 and compressors 4 according to the required heat dissipation; each evaporator 2 is connected to the corresponding compressor 4 via a refrigerant outlet pipe; each compressor 4 is connected to the gaseous refrigerant distribution main pipe 11 via its respective port; each evaporator 2 is connected to the liquid refrigerant storage tank 6 via its respective refrigerant inlet pipe 25, and each refrigerant inlet pipe 25 is provided with an expansion valve respectively; there are also multiple groups of cabinet cooling ends 35, and each group of cabinet cooling ends 35 is connected to the corresponding evaporator 2 via its respective heat transfer oil circuit; in addition, each gaseous refrigerant riser is provided with a valve near the inlet end, each gaseous refrigerant branch pipe is provided with a valve, and each liquid refrigerant collection main pipe is provided with a valve near the outlet end; each oil supply branch pipe is provided with a valve; these are used to control the flow and opening and closing of the corresponding pipelines to meet the heat dissipation requirements of different heat amounts.

[0035] More specifically, multiple compressors are installed in the computer room on the roof of the computing center. The high-temperature and high-pressure gaseous refrigerant at the outlet of the compressor is sent to the gaseous refrigerant distribution main pipe around the top of the computing center building. A plurality of gaseous refrigerant risers are provided on the gaseous refrigerant distribution main pipe, and the gaseous refrigerant risers are vertically installed on the outer wall of the building; each gaseous refrigerant riser is connected to its own multiple gaseous refrigerant branch pipes. Under the control of the valve, the high-temperature and high-pressure gaseous refrigerant enters the corresponding radiation plate condensing unit through the gaseous refrigerant distribution main pipe, the gaseous refrigerant riser, and the gaseous refrigerant branch pipes. The radiation plate condensing unit emits the heat of the refrigerant to the surface of objects in the external environment and the greenhouse gases in the air in the form of radiation heat transfer; the high-temperature and high-pressure gaseous refrigerant condenses into liquid refrigerant and flows out from the refrigerant heat transfer pipe of the radiation plate condensing unit. After passing through the liquid refrigerant branch pipes and liquid refrigerant risers, the liquid refrigerant is collected in the liquid refrigerant collection main pipe and then stored in the liquid refrigerant storage tank. The liquid refrigerant collection main pipe is laid to the ceiling level of the computing center's first floor. Multiple evaporators are located in the air-conditioning room on the ground floor of the computing center. The liquid refrigerant then enters the corresponding evaporator through its respective refrigerant inlet pipe to exchange heat with the thermal oil inside the evaporator. After absorbing heat, the liquid refrigerant forms a high-temperature, low-pressure gaseous refrigerant. This high-temperature, low-pressure gaseous refrigerant then rises through the refrigerant outlet pipes laid vertically throughout the room to the rooftop computer room and enters the corresponding compressor for compression, forming a high-temperature, high-pressure gaseous refrigerant. The evaporator is located on the ground floor, and the compressor is located on the top floor. The gaseous refrigerant is transported through vertical refrigerant outlet pipes, which prevents wet compression caused by refrigerant vapor carrying liquid. After passing through the evaporator, the thermal oil becomes low-temperature thermal oil. The low-temperature thermal oil absorbs heat from the equipment area and then flows through the oil discharge branch pipe and the oil discharge main pipe into the evaporator to cool down and form low-temperature thermal oil.

[0036] In this embodiment, the thermal oil has a condensation temperature of -25°C, is electrically insulating, and is fireproof. As a heat transfer medium for computer room cooling equipment, it can provide a sub-zero cooling source to cool computing equipment. Compared to water, the frictional resistance between thermal oil molecules is much lower, resulting in lower transport power consumption than water. That is, at the same power consumption, the flow rate of thermal oil is greater than that of water, and increased flow rate increases heat exchange capacity.

[0037] In this embodiment, the radiation plate condensing unit used can emit heat to the surfaces of various objects in the external environment through the metal panel when the high-temperature refrigerant passes through. More importantly, it emits heat to CO2, H2O, O3, etc. in the air. When the traditional cooling tower encounters high humidity conditions such as rainy days, the evaporation efficiency of the cooling tower becomes low, and the temperature of the cooling water cannot be reduced to the required temperature, resulting in a poor cooling effect. However, this problem does not exist in the radiation plate condensing unit of this embodiment. At the same time, the radiation plate condensing unit of this embodiment does not use cooling water to dissipate heat and cool down, eliminating the traditional refrigerant-water heat exchange condenser, water pump and cooling tower, effectively solving the problem of the computing power center's dependence on water resources.

[0038] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
