Description

Technical Field

[0001] This utility model belongs to the technical field of small liquid cooling systems, specifically relating to a small edge immersion liquid cooling system. Background Technology

[0002] Against the backdrop of the explosive growth in domestic AI applications and the demand for localized computing power, small edge immersion liquid cooling systems have become a key technology for resolving the contradiction between high-density computing power, space constraints, and operation and maintenance costs.

[0003] Internationally, liquid cooling technology research and development focuses on ultra-large data center scenarios, while small-scale edge systems are still in their infancy. Some North American companies have launched modular liquid-cooled racks adapted for edge data center renovations, but these still rely on professional operation and maintenance, with a single unit costing over one million yuan, making it difficult to meet the localization needs of small and medium-sized enterprises. Europe, on the other hand, emphasizes environmental protection and energy recycling, with major data centers located on the outskirts of key cities in countries like the UK, Germany, and the Netherlands, building medium-to-large data centers. Due to their proximity, these data centers can provide users in Europe with an ultra-low latency access experience. Furthermore, Europe's strict data protection regulations provide higher security. The demand for such locally deployed computing servers differs significantly from that in China.

[0004] Domestically, driven by both policy and market demand, small-scale edge liquid cooling systems are experiencing rapid breakthroughs. Domestic companies have launched modular liquid cooling solutions, primarily designed to meet the edge computing node deployment needs of medium to large-scale industrial parks. However, dedicated data centers are still required to support the deployment of related facilities and equipment. Currently, the market lacks products specifically designed for localized deployment scenarios such as startup parks, SMEs, and research laboratories, which typically require: adaptability to confined installation environments, rapid deployment, a power consumption requirement of PUE < 1.2, low noise to avoid impacting surrounding offices, and support for operation by non-professionals.

[0005] In summary, the domestic and international small edge liquid cooling systems industry suffers from the pain point of "excessive foreign technology and insufficient adaptation to domestic scenarios". Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned problems. This application proposes a small edge immersion liquid cooling system, which is an immersion liquid cooling system that combines "extreme miniaturization, full-scenario adaptability and low-cost operation and maintenance", which is of great significance for promoting the green and localized deployment of edge computing power.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a small edge immersion liquid cooling system, including an immersion liquid cooling cabinet and a dry cooler connected thereto. The immersion liquid cooling cabinet includes a cabinet body, with maintenance doors on both the front and back of the cabinet body. A control panel is installed on the cabinet body, and an inlet / outlet and a cable inlet are provided on the left side. A control box is located above the inlet / outlet and the cable inlet. An upper flip-up cover is provided on the top of the cabinet body, and an observation window and a control panel are provided on the upper flip-up cover. The cabinet is equipped with a server mounting plate that divides the cabinet into a liquid inlet area and a liquid return area. The liquid return area is equipped with a liquid return tank located at the top. The liquid inlet area is located at the bottom of the cabinet and is equipped with a DC power supply tank. Several liquid inlet holes are evenly distributed on both sides of the DC power supply tank. The server mounting plate and the inner wall of one side of the cabinet are equipped with server positioning slots for installing the server.

[0008] Furthermore: the dry cooler is equipped with a heat exchanger and a temperature sensor inside, and a fan is installed on the outside.

[0009] Furthermore, the heat exchanger is connected to the immersion liquid cooler via two pipelines. One pipeline passes through a butterfly valve, a temperature sensor, and a pressure sensor in sequence before connecting to the immersion liquid cooler. The other pipeline passes through a butterfly valve, a flow meter, and pressure sensors located on both sides of the filter in sequence before connecting to the one-way valve, the circulation pump, and the butterfly valve of the immersion liquid cooler, and finally enters the cabinet body.

[0010] Furthermore, the control panel is located on the front side above the maintenance door and on the side of the observation window at the top of the cabinet.

[0011] Furthermore, the immersion liquid cooler is equipped with a liquid level switch, a temperature sensor, and a liquid level sensor inside the cabinet.

[0012] Furthermore, the server is a modular server.

[0013] Furthermore, the internal space of the immersion liquid cooler is not less than 16U.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Small, edge-oriented, and compact design enables rapid deployment and maintenance. Space adaptability: It adopts a single-layer compact immersion architecture, occupying less than 1m² of floor space. 2 It can be directly deployed in non-computer room environments such as offices and laboratories without the need for dedicated infrastructure modifications; Rapid deployment: Integrated quick-installation piping interfaces support full-process deployment from unpacking to startup within 4 hours; Lightweight operation and maintenance: The weight of a single server is ≤30kg, which can be set up and dismounted by a single person. It is equipped with a touch screen intelligent monitoring system, and non-professionals can also complete daily operations through preset menus, solving the pain point of "lack of professional operation and maintenance" in edge scenarios.

[0015] High-efficiency liquid cooling It adopts a natural convection path of "bottom inlet + top outlet" and uses viscosity-immersed synthetic oil to make the coolant flow rate uniform. The chip core temperature is reduced by ≥5℃ compared with air cooling. The single system heat dissipation power reaches 12kW. It is compatible with combinations such as 2 6U high-performance GPU servers or 4 3U general-purpose servers. Dual-circulation pump redundancy: Innovative integration of dual pumps (one in use and one on standby) and outdoor dry cooler, with an annual natural cooling source utilization rate of over 80%, system PUE < 1.2, and energy savings of 20%-40% compared to traditional air-cooled solutions; High reliability design: Pressure and flow sensors are deployed on critical pipelines, and abnormal data is alerted within seconds. Combined with a fully enclosed liquid cooling cycle, it meets the 24 / 7 uninterrupted operation requirements of edge nodes.

Detailed Implementation

[0019] To enable those skilled in the art to better understand and implement the technical solution of this utility model, the present utility model will be further described below with reference to specific embodiments. However, the embodiments are only for illustration and are not intended to limit the present utility model.

[0020] like Figures 1-7 The small edge immersion liquid cooling system shown includes an immersion liquid cooler (TANK) and a dry cooler A connected thereto. The dry cooler A is equipped with a heat exchanger 15 and a temperature sensor 17 inside, and a fan 16 outside. The immersion liquid cooler includes a cabinet body 1. The cabinet body 1 has maintenance doors 2 on both the front and back. The left side of the cabinet body 1 has a liquid inlet / outlet 5 and a cable inlet 6. A control box 4 is located above the liquid inlet / outlet 5 and the cable inlet 6. The top of the cabinet body 1 has an upturned cover 8 with an observation window 7. The front of the cabinet body 1 is also equipped with a control panel 3 above the maintenance door 2. The top of the cabinet body 1 is also equipped with a control panel 3 on the side of the observation window 7. The two locations share a single control panel. The cabinet 1 is equipped with a server mounting plate 13, which divides the cabinet 1 into a liquid inlet area and a liquid return area. The liquid return area is equipped with a liquid return tank 11, which is located at the top. The liquid inlet area is located at the bottom of the cabinet 1 and is equipped with a DC power supply tank 10. Several liquid inlet holes 14 are evenly opened on both sides of the DC power supply tank 10. The server mounting plate 13 and the inner wall of one side of the cabinet 1 are equipped with server positioning slots 12 for installing servers. The server is a modular server that supports internationally advanced CPUs / GPUs and domestic CPUs / GPUs. The cabinet of the immersion liquid cooling cabinet can provide 16U of space and can install no less than two 6U servers. The weight of a single server is about 30kg. It is placed vertically in the cabinet of the immersion liquid cooling cabinet.

[0021] The immersion liquid cooler cabinet 1 is equipped with a liquid level switch, a temperature sensor, and a liquid level sensor to monitor and control the flow rate, pressure, and temperature of the coolant.

[0022] The heat exchanger 15 is connected to the immersion liquid cooler via two pipelines. The pipelines are connected to the heat exchanger 15 inside the dry cooler A through the inlet and outlet liquid ports 5 on the cabinet body 1. One pipeline passes through a butterfly valve, a temperature sensor, and a pressure sensor in sequence before connecting to the cabinet body 1. The other pipeline passes through a butterfly valve, a flow meter, and pressure sensors installed on both sides of the filter in sequence before finally connecting to the cabinet body 1 of the immersion liquid cooler through a check valve, a circulation pump, and a butterfly valve.

[0023] Preferably, the external AC power supply is connected to the centralized power supply module through the cable inlet 6 and converted into DC power for the server. The DC power supply tank 10 provides DC power to the server inside the cabinet 1, effectively reducing the number of server power supply modules and improving the energy utilization efficiency of the immersion liquid cooler and the server.

[0024] Working principle This utility model's liquid cooling system completely immerses the server in coolant within the cabinet. The coolant's excellent thermal conductivity absorbs the heat generated by the equipment, and the heat is then carried away through a circulation system between the immersion liquid cooler and the dry cooler, achieving efficient heat dissipation. The specific workflow of this system is as follows: Coolant enters the cabinet through the inlet and outlet ports at the bottom of the immersion liquid cooler. The liquid flow carries away the server's heat and flows into the return water pipe through the return tank at the top of the tank. Since the immersion liquid cooler is connected to the dry cooler, the coolant can dissipate heat through the outdoor dry cooler and complete the circulation.

[0025] Features of this liquid cooling system Maximum heat dissipation: 12kW; Dual circulation pumps, one in use and one on standby; Dimensions: 990×720×1109mm (length, width, height, including casters); Space: 16U; Weight: 190kg (excluding server and coolant); Voltage standard: 380V / 220V 50Hz; Technical features of outdoor dry coolers: Dimensions: 1080×362×720 (length×width×height); Weight: ≤70kg; Voltage standard: 220V 50Hz; Dual fan parallel design; Hose connection; The performance achieved by the liquid cooling system of this invention is as follows: 1. Miniaturization: Extremely compact design enables rapid deployment and maintenance.

It is equipped with a touch control screen intelligent monitoring system. Non-professionals can complete daily operations through preset menus, solving the pain point of "lack of professional operation and maintenance" in edge scenarios.

[0026] 2. High-efficiency liquid cooling: Low PUE design ensures stable operation of high-density computing power. It adopts a "bottom inlet + top outlet" circulation path, combined with low viscosity immersion synthetic oil, so that the coolant flow rate is uniform, the chip core temperature is reduced by ≥5℃ compared with air cooling, the single system heat dissipation power reaches 12kW, and it is compatible with combinations such as two 6U high-performance GPU servers. Dual-pump redundant circulation: Innovatively integrates dual circulation pumps (one in use and one on standby) with an outdoor dry cooler, achieving an annual natural cooling source utilization rate of over 80%, a system PUE of <1.2, and energy savings of 20%-40% compared to traditional air-cooled solutions; High reliability design: Pressure, flow and temperature sensors are deployed on critical pipelines, and abnormal data is alerted within seconds. Combined with a fully enclosed liquid cooling cycle, it meets the 24 / 7 uninterrupted operation requirements of edge nodes.

Quiet operation: The fully enclosed liquid cooling circulation and low-noise fan design result in an operating noise level of <55dB, achieving ultra-quiet operation. It can be directly deployed in noise-sensitive environments such as office areas and laboratories.

[0029] 5. Deeply adaptable to specific scenarios: focusing on the needs of SMEs and edge nodes. Compatible with non-data center environments: No dedicated data center is required, making it suitable for localized scenarios such as startup parks, SMEs, and research laboratories.
