[0002] Data center cooling systems refer to the facilities used to keep servers and other equipment in data centers running at appropriate operating temperatures. As the power density of servers and other equipment in data centers continues to increase, cooling systems are critical to ensuring the normal operation of equipment and preventing overheating.

[0003] A Chinese utility model patent with publication number CN219802944U discloses a heat dissipation device for a server used in an e-commerce platform, which belongs to the technical field of heat dissipation devices. The key points of its technical solution include a server, a fan and a box. The server is installed inside the box. A shelf structure is installed at the bottom of the box. The server is placed on the upper part of the shelf structure. The fan is installed at the front of the server. A liquid cooling pipe is arranged inside the server.

[0004] The above-mentioned e-commerce platform uses a server cooling device. The fan installed at the front of the server can blow air to cool the server. The hot air is blown out from the rear slot to form an air duct, and at the same time cooperates with liquid cooling to absorb heat to form a heat dissipation mechanism. However, when the air duct is used to dissipate heat on the server box, it will also be connected to the outside, and dust will inevitably enter, affecting the environment and posing a safety hazard.

[0005] Therefore, a data center liquid cooling device is provided to solve the above problems. Utility Model Content

[0028] 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.

[0029] See also Figure 1-Figure 4 The utility model provides a technical solution: a liquid cooling device for a data center, comprising a server cabinet 1, a mounting frame 11 fixedly mounted at four corners of the server cabinet 1, and a heat dissipation mechanism 2 arranged on the server cabinet 1.

[0030] The heat dissipation mechanism 2 includes a plurality of copper tube cooling plates 27 fixedly mounted on the mounting frame 11 and distributed in a linear array, a circulation box 21 fixedly mounted on the outer wall of the server cabinet 1, a circulation pump 22 fixedly mounted on the outer wall of the server cabinet 1 and having its inlet end connected to the outlet end of the circulation box 21, an upper water diverter pipe 23 fixedly connected between the outlet end of the circulation pump 22 and the inlet end of the copper tube cooling plate 27, a manifold 24 fixedly connected at its inlet end to the outlet end of the copper tube cooling plate 27, a coil 25 fixedly connected at its inlet end to the outlet end of the manifold 24, and a heat exchange box 26 wrapped around the outside of the coil 25 and fixedly connected to the server cabinet 1, wherein the outlet end of the coil 25 passes through the heat exchange box 26 and is connected to the inlet end of the circulation box 21.

[0031] The heat exchange box 26 has a water inlet 261 and a water outlet 262 , and the heat exchange box 26 is connected to an external heat exchange system through the water inlet 261 and the water outlet 262 .

[0032] An insulation layer 13 is fixedly connected at a position corresponding to between the copper tube cooling plate 27 and the manifold 24 in the server cabinet 1, and a partition 131 is fixedly connected at a position corresponding to between the upper water manifold 23 and the manifold 24 in the server cabinet 1. The insulation layer 13 and the partition 131 isolate a heat dissipation cavity 132 for accommodating the manifold 24 in the server cabinet 1. Air intake louvers 3 for air intake and ventilation fans 4 for exhaust are respectively arranged at positions corresponding to the heat dissipation cavity 132 on the server cabinet 1, and the partition 131 is fixedly connected to the insulation layer 13 and the inner wall of the server cabinet 1.

[0033] When in use, the server host is placed on the copper tube cooling plate 27 of each layer respectively, and the condensate in the circulation box 21 is guided by the circulation pump 22, and sent to the copper tube cooling plate 27 of each layer through the upper water diverter 23, and then converged into the coil 25 through the confluence pipe 24, and finally returned to the circulation box 21 from the coil 25, and the cycle is repeated. During the process, the copper tube cooling plate 27 absorbs the heat of the server host and transfers it to the condensate. When the condensate passes through the coil 25, the heat exchange box 26 is connected to the external heat exchange system, so that the heat absorbed by the condensate in the coil 25 is exchanged, and this part of the heat is collected and reused through the external heat exchange system. The cooled condensate passes through the coil 25 returns to the circulation box 21, thereby completing the heat dissipation of the server cabinet 1. At the same time, since the manifold 24 is isolated in the heat dissipation cavity 132 by the insulation layer 13 and the partition 131, when the condensate that absorbs heat circulates in the manifold 24, the dissipated heat will not affect the copper tube cooling plate 27 and the upper water diverter 23 next to it, thereby improving the heat dissipation effect through reasonable spatial distribution, and then, the hot air in the heat dissipation cavity 132 is exchanged with the external cold air through the ventilation fan 4 and the air intake louver 3, further improving the heat dissipation efficiency and sharing the heat exchange burden of the heat exchange box 26. In general, the sealing of the host area in the server cabinet 1 is maintained, the influence of dust on the server is avoided, and safety hazards are avoided.

[0034] Specifically, the air intake louver 3 is fixedly installed on the server cabinet 1 at a position corresponding to the bottom of the heat dissipation cavity 132, and the ventilation fan 4 is fixedly installed on the server cabinet 1 at a position corresponding to the top of the heat dissipation cavity 132; by utilizing the principle of rising hot air, the air intake louver 3 is set at the bottom and the ventilation fan 4 is set at the top, which can improve the internal and external ventilation efficiency and is beneficial to energy saving.

[0035] Furthermore, a dust filter 31 is fixedly installed on the inner side of the air intake louver 3, and a dust cover 41 is mounted on the outer side of the ventilation fan 4 and is fixedly connected to the server cabinet 1; by providing the dust filter 31 and the dust cover 41, the inhalation of dust during ventilation can be effectively avoided, and the dust accumulation that affects the heat dissipation efficiency of the manifold 24 can be avoided.

[0036] Furthermore, the outer wall of the manifold 24 has a plurality of fins 241 distributed in a linear array; by providing the fins 241 on the outer wall of the manifold 24, the heat dissipation efficiency of the manifold 24 can be improved, and the heat dissipation effect can be further improved.

[0037] If replenishment is needed, the circulation box 21 is provided with a liquid replenishment port 211 and a liquid discharge port 212. Considering the consumption of the condensate, the liquid replenishment port 211 is provided on the circulation box 21, so that the condensate can be replenished through the liquid replenishment port 211. Considering the cleaning of the circulation box 21, the liquid discharge port 212 and the liquid replenishment port 211 can be used for cleaning.

[0038] It can be understood that the side of the server cabinet 1 away from the heat exchange box 26 has a transparent cabinet door 12; the internal host status can be directly observed through the transparent cabinet door 12, which is convenient for inspection and judgment.

[0039] 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.
