Description

Technical Field

[0001] The utility model relates to the field of data centers, in particular to a modular data center energy-saving device. Background Art

[0002] A data center is a facility that realizes centralized processing, storage, transmission, exchange, and management of information in a physical space. It usually includes key equipment such as computer equipment, server equipment, network equipment, storage equipment, and auxiliary facilities such as cooling, power supply, monitoring, and management systems.

[0003] A Chinese utility model patent with publication number CN220044041U discloses a modular data center computer room energy-saving device, which takes away the heat generated by the host through an overall closed water flow structure, and adds an external power generation structure to the water circulation cooling structure for power generation and reuse. However, the heat exchange of the circulating water occurs inside the computer room, and the hot water after absorbing heat will dissipate more heat as the pipeline increases during the transportation to the outside of the computer room, resulting in a lower heat recovery rate.

[0004] Therefore, a modular data center energy-saving device is provided to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The utility model provides a modular data center energy-saving device, aiming to solve the problem that the existing data center computer room energy-saving device proposed in the background technology is prone to more heat energy dissipation of recovered hot water due to long pipelines, resulting in a low waste heat recovery rate.

[0007] (II) Technical solution

[0008] To achieve the above objectives, the utility model provides the following technical solutions: a modular data center energy-saving device, comprising a machine room, a plurality of cabinets arranged in a rectangular array in the machine room, and a circulating heat dissipation mechanism arranged on the machine room.

[0009] In order to directly transport heat energy in the form of gas to reduce losses in the heat recovery process, the circulating heat dissipation mechanism includes secondary shunt pipes and secondary collectors respectively connected to the bottom and top of the cabinet, a main shunt pipe fixedly connected to the other end of all the secondary shunt pipes, a main collector fixedly connected to the other end of all the secondary collectors, a heat exchange tank fixedly installed outside the machine room, a coil fixedly connected to the inside of the heat exchange tank, a blower connected at both ends to the other end of the main shunt pipe and one end of the coil respectively, and an air suction fan connected at both ends to the other end of the main collector and the other end of the coil respectively; through the circulating heat dissipation mechanism, the hot air in the machine room is circulated to the heat exchange tank by using the air suction fan and the blower for unified heat exchange, thereby avoiding the transportation of coolant after direct heat exchange in the machine room, thereby avoiding the heat loss generated during liquid transportation, and reducing the heat dissipation of pipe fittings by gas transportation, thereby ensuring the heat recovery rate.

[0010] In order to enable the heat exchange tank to perform cyclic heat exchange and recover heat energy to the external power generation system for utilization, the heat exchange tank is connected to the cooling water outlet and hot water inlet of the external power generation system through the water inlet pipe and the water outlet pipe respectively; by connecting the inlet and outlet water of the heat exchange tank to the cooling water inlet and outlet of the external power generation system, it is ensured that heat exchange can occur in the heat exchange tank, thereby recovering heat energy.

[0011] In order to save space and prevent the secondary shunt pipe from undergoing heat exchange in advance, a base is provided at the bottom of the machine room, a pipe groove for accommodating the secondary shunt pipe is provided on the base, and a cover plate is connected to the pipe groove; by burying the secondary shunt pipe in the base, the contact with the air inside the machine room is reduced, thereby preventing the cold air in the secondary shunt pipe from undergoing heat exchange in advance, thereby ensuring the cooling effect entering each cabinet.

[0012] Preferably, in order to save space in the machine room and reduce noise in the machine room, the ends of the secondary shunt pipe and the secondary collector away from the cabinet extend to the outside through the wall of the machine room; by extending the secondary shunt pipe and the secondary collector to the outside of the machine room, it is ensured that both fans and the heat exchange tank can be arranged outside the machine room, thereby saving space in the machine room and avoiding noise from the fans.

[0013] Preferably, in order to ensure that cold air flows into the cabinet from the secondary shunt pipe, the outlet and inlet ends of the coil are respectively connected to the inlet end of the air supply fan and the outlet end of the suction fan; by setting the wind direction of the air supply fan and the suction fan, it is ensured that cold air flows into the secondary shunt pipe.

[0014] Preferably, in order to stabilize the heat exchange tank, the base has a support base fixedly connected to the heat exchange tank; by arranging the support base on the base to support and fix the heat exchange tank, welding or punching fixings on the outer wall of the heat exchange tank can be avoided, thereby facilitating the replacement and reuse of the heat exchange tank.

[0015] Preferably, in order to reduce the use of pipes and thus reduce heat energy loss, the air supply fan and the air suction fan are respectively fixedly connected to the support base at positions corresponding to the two ends of the coil; by reducing the distance between the air supply fan and the air suction fan and the interface of the heat exchange tank, the investment in pipes is reduced, thereby reducing heat energy loss during transportation.

[0016] Preferably, in order to improve the heat exchange efficiency, the water inlet pipe and the outlet end of the coiled tube are on the same side; by having the water inlet pipe and the outlet end of the coiled tube on the same side, it can be ensured that the flow direction of external cooling water and the flow direction of hot air are opposite, thereby improving the heat exchange effect and the heat energy recovery rate.

[0017] Preferably, in order to further save energy, the top of the machine room is provided with a solar roof; the solar roof converts solar energy into electricity for use in the machine room and the circulating heat dissipation mechanism, which can further reduce costs.

[0018] (III) Beneficial effects

[0019] This modular data center energy-saving device achieves effective recovery and utilization of hot air inside the cabinet through a circulating heat dissipation mechanism, significantly improving the efficiency of heat recovery. The water circulation system composed of the heat exchange tank in the device and the external power generation system not only ensures the supply of cold air inside the cabinet, but also converts the recovered heat energy into hot water for the external power generation system, thus achieving energy recycling.

[0020] The modular data center energy-saving device has a solar roof on the top of the computer room that provides clean energy for the electrical facilities in the computer room, further reducing electricity consumption and achieving the effects of energy conservation, emission reduction, and green environmental protection. The entire device is cleverly designed and compactly structured, effectively improving the energy utilization efficiency and environmental performance of the data center.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example 1

[0032] See also Figure 1-Figure 5 The utility model provides a technical solution: a modular data center energy-saving device, including a computer room 1, a plurality of cabinets 14 arranged in a rectangular array in the computer room 1, and a circulating heat dissipation mechanism 2 arranged on the computer room 1.

[0033] The circulating heat dissipation mechanism 2 includes a secondary shunt pipe 25 and a secondary collector pipe 26 respectively connected to the bottom and top of the cabinet 14, a main shunt pipe 24 fixedly connected to the other end of all secondary shunt pipes 25, a main collector pipe 27 fixedly connected to the other end of all secondary collector pipes 26, a heat exchange tank 21 fixedly installed outside the machine room 1, a coil 22 fixedly connected to the inside of the heat exchange tank 21, a blower 23 having two ends respectively connected to the other end of the main shunt pipe 24 and one end of the coil 22, and a suction fan 28 having two ends respectively connected to the other end of the main collector pipe 27 and the other end of the coil 22, wherein the outlet end and the inlet end of the coil 22 are respectively connected to the inlet end of the blower 23 and the outlet end of the suction fan 28.

[0034] The heat exchange tank 21 is connected to the cooling water outlet and the hot water inlet of the external power generation system through the water inlet pipe 211 and the water outlet pipe 212 respectively.

[0035] A base 11 is provided at the bottom of the machine room 1 . A pipe groove 111 for accommodating the secondary shunt pipe 25 is provided on the base 11 . A cover plate 112 is connected to the pipe groove 111 .

[0036] When in use, the hot air in all the cabinets 14 is guided from the top into the secondary manifold 26 through the air supply fan 23 and the suction fan 28, and then enters the coil 22 through the suction fan 28 after being collected by the main manifold 27. After heat exchange with the cooling water in the heat exchange tank 21, the hot air that has lost heat is converted into cold air and transported to the main shunt pipe 24 by the air supply fan 23, and then enters all the cabinets 14 from the bottom through the shunt of the secondary shunt pipe 25, and then circulates. During the process, the heat exchange tank 21 is still in the water circulation system composed of the external power generation system, and the coil 22 exchanges heat with the cooling water in the heat exchange tank 21. Heat exchange, hot water is transported to the external power generation system through the outlet pipe 212 for power generation, and the cooling water flowing out of the external power generation system enters the heat exchange tank 21 again through the inlet pipe 211, and so on. Since the secondary shunt pipe 25 is arranged in the pipe groove 111 of the base 11, the cold air is avoided from contacting with the hot air inside the machine room 1 through the cover plate 112 before flowing into the cabinet 14, thereby ensuring the cooling effect. In addition, the hot air in the machine room 1 is on the top and the cold air is on the bottom, which can further ensure that the secondary manifold 26 above the cabinet 14 reduces heat loss when transporting hot air, thereby improving the recovery efficiency of heat energy.

[0037] Specifically, one end of the secondary shunt pipe 25 and the secondary collector pipe 26 away from the cabinet 14 passes through the wall of the computer room 1 and extends to the outside; by extending the ends of the secondary shunt pipe 25 and the secondary collector pipe 26 to the outside of the computer room 1, the remaining structure is ensured to be outside the computer room 1, thereby saving space in the computer room 1 and reducing noise in the computer room 1.

[0038] In addition, the base 11 has a support base 13 fixedly connected to the heat exchange tank 21, and the air supply fan 23 and the air suction fan 28 are respectively fixedly connected to the support base 13 at positions corresponding to the two ends of the coil 22; the support base 13 on the base 11 provides stable support for the heat exchange tank 21, and it is also convenient to set the air supply fan 23 and the air suction fan 28 nearby at the two ends of the coil 22, thereby reducing the investment in pipe fittings and reducing the loss of heat energy transmission.

[0039] Furthermore, the water inlet pipe 211 and the outlet end of the coiled tube 22 are on the same side; by arranging the water inlet pipe 211 and the outlet end of the coiled tube 22 on the same side, the gas flow direction in the coiled tube 22 is opposite to the cooling water flow direction in the heat exchange tank 21, which helps to improve the heat exchange efficiency.

[0040] Example 2

[0041] Different from the first embodiment, a solar roof 12 is provided on the top of the machine room 1 .

[0042] The solar roof 12 is connected to the power facilities in the machine room 1 and the power equipment in the circulating heat dissipation mechanism 2 to provide them with electricity, which can effectively reduce the input of electricity and further achieve energy conservation, emission reduction and green environmental protection.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
