Description

Technical Field

[0001] The utility model belongs to the technical field of data centers, and in particular relates to a liquid-cooled phase-change energy storage server cabinet. Background Art

[0002] A data center is a global collaborative network of specific devices used to transmit, accelerate, display, calculate, and store data information on the Internet network infrastructure.

[0003] In the future, data centers will also become competitive assets for enterprises, and business models will change accordingly. With the widespread application of data centers, artificial intelligence, network security, etc. have also emerged, and more users have been brought to the application of the Internet and mobile phones. With the increase in computers and data, people can also improve their abilities through continuous learning and accumulation, which is an important sign of moving towards the information age.

[0004] Traditional data centers use room-level cooling. In summer or high temperature environments, air conditioning is used to cool the entire data center. This method has a long cooling path and low efficiency. It cannot effectively meet the cooling and heat dissipation needs of high-power consumption equipment, and it consumes a lot of energy. In addition, the thermal conductivity of liquid is 25 times that of air. Under the same volume, the heat carried away by liquid is nearly 3,000 times that of air. From the perspective of noise, at the same heat dissipation level, the noise of liquid cooling is 20-35 decibels lower than that of air cooling. From the perspective of energy consumption, liquid cooling saves 30%-50% of electricity compared to air cooling. At present, server liquid cooling technology is generally favored by the industry, but it is still in the exploratory stage and has a very broad market prospect. Cold plate liquid cooling refers to a non-contact liquid cooling technology that uses liquid as a heat transfer medium to flow in the internal flow channel of the cold plate and cools the heat source through heat transfer. The heat is transferred through the cold plate installed on the electronic components to be cooled, and then the heat exchange between the cold plate and the liquid medium is realized, which is called non-contact liquid cooling. However, there are problems such as uneven distribution of coolant flow and difficulty in fault repair in the liquid cooling system. Therefore, in response to the above problems, a liquid-cooled phase change energy storage server cabinet is proposed. The purpose of the present invention is to combine the liquid cooling device with the phase change cold storage technology for heat dissipation design to achieve energy-saving and cooling effects. Summary of the invention

[0005] In view of the shortcomings of the above-mentioned prior art, the utility model provides a liquid-cooled phase change energy storage server cabinet, which combines liquid cooling components with phase change cold storage technology. Phase change cold storage technology can release or absorb a large amount of heat during the phase change process, effectively improving the cooling efficiency. Phase change cold storage technology utilizes the heat changes in the phase change process, saves energy and is environmentally friendly, reduces energy consumption, and combines with liquid cooling components to achieve uniform allocation of coolant flow and improve the overall cooling effect. The combination of technologies makes the system more stable, maintenance more convenient, and reduces maintenance costs.

[0014] Furthermore, the phase change cold storage module includes a heat exchange coil and a phase change cold storage material. The heat exchange coil is located inside the cavity of the phase change cold storage module.

The cavity of the phase change cold storage module is filled with phase change cold storage material.

[0015] Furthermore, heat dissipation holes are provided on the front and back sides of the cabinet.
