Description

Technical Field

[0001] The utility model relates to the technical field of server chassis, in particular to a blade server chassis with high-efficiency heat dissipation. Background Art

[0002] A blade server is a server design that efficiently utilizes space and resources. It achieves this by integrating multiple server modules (or "blades") within a single chassis. Each blade is an independent server unit that can contain components such as a processor, memory, and storage devices. These blades share infrastructure such as power supplies, cooling systems, and network connections, significantly reducing hardware redundancy and improving energy efficiency and ease of management. Blade servers were originally designed to address the growing space constraints and energy consumption issues in data centers, providing a more compact, easily scalable, and maintainable solution. With the growing demand for cloud computing and big data processing, blade servers have been widely used in modern data centers due to their flexibility and high density.

[0003] Compared with traditional rack-mounted servers, blade servers have the advantage of higher space utilization. However, traditional blade servers mainly rely on built-in or external fans for forced air cooling to achieve heat dissipation, but the fan cooling efficiency is limited. In high-density deployment, the fan may not provide sufficient airflow to effectively remove the generated heat. Especially when the server runs at high load for a long time, it is easy to cause the internal components to overheat, especially the bottom of the hardware. Since it needs to be installed on the baseboard, the fan wind is difficult to blow, resulting in a large amount of heat accumulation between the hardware and the baseboard, thereby affecting server performance and even causing hardware damage.

[0006] A blade server chassis with efficient heat dissipation includes a chassis body, guide frames are symmetrically installed on both side walls of the chassis body, and a push-pull assembly with a U-shaped structure is slidably installed through the cooperation of the two guide frames, the chassis body is symmetrically installed with a mounting frame at one end of the push-pull assembly, and a number of base plates are installed through the cooperation of the two mounting frames, the upper surface of the base plates are used for installing server hardware, liquid cooling grooves are provided in the base plates, both ends of the liquid cooling grooves pass through the base plates for installing liquid cooling pipes, and the two ends of the liquid cooling pipes respectively extend out of the base plates, and a liquid inlet pipe and a liquid outlet pipe are also placed in the chassis body, the liquid inlet pipe is connected to the liquid inlet ends of the liquid cooling pipes, and the liquid outlet pipe is connected to the liquid outlet ends of the liquid cooling pipes, one end of the liquid inlet pipe and the liquid outlet pipe both extend out of the chassis body and are connected to an external liquid cooling device.

[0007] Furthermore, the push-pull assembly includes a symmetrically arranged support frame 1, a support frame 2 and a connecting piece. The support frame 1 and the support frame 2 are provided with a number of corresponding guide holes. The corresponding guide holes on each side are slidably connected to a guide rod. One end of each two horizontally corresponding guide rods is cooperated with and installed with a front plate, and the other ends of the several guide rods on both sides are respectively connected by connecting pieces.

[0012] Beneficial effects of the utility model:

[0013] In this utility model, when the server hardware is running, the heat generated is first transferred to the bottom plate, and the bottom plate then conducts the heat to the liquid cooling pipe in the liquid cooling tank. Since the liquid cooling pipe is in close contact with the bottom plate, it can absorb the heat quickly and effectively. Subsequently, the coolant in the liquid cooling tank absorbs the heat and carries it out of the chassis body through the liquid outlet pipe and returns it to the external liquid cooling device for cooling treatment. The cooled fluorinated liquid enters the chassis again through the liquid inlet pipe and continues to be recycled, forming an efficient cooling cycle process.

[0014] The utility model increases the contact area with the coolant and improves the heat exchange efficiency by setting a U-shaped liquid cooling tank inside the bottom plate. It can quickly and effectively take away the heat generated during the operation of the server hardware, ensuring that the server can maintain a good operating temperature under high load conditions.

[0015] Other features and advantages of the present invention will be described in detail in the subsequent detailed description of the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Please refer to Figure 1-10 ;

[0029] A blade server chassis with high heat dissipation is used to improve the heat dissipation efficiency of the server during operation and ensure the stable operation of the hardware; it specifically includes a chassis body 1, guide frames 2 are symmetrically installed on the two side walls of the chassis body 1, and a U-shaped push-pull component 3 is slidably installed through the cooperation of the two guide frames 2, so as to achieve smooth movement of the push-pull component 3, and the chassis body 1 is symmetrically installed with a mounting frame 4 at one end of the push-pull component 3, and a plurality of bottom plates 5 are installed through the cooperation of the two mounting frames 4. The bottom plates 5 are used to install server hardware, and liquid cooling tanks 51 are provided in the bottom plates 5. Preferably, the liquid cooling tank 51 is provided in the bottom plates 5. The groove 51 has a U-shaped structure in the length direction, which helps to increase the heat dissipation area and thus improve the heat exchange efficiency. Both ends of the liquid cooling groove 51 pass through the bottom plate 5. A liquid inlet pipe 53 and a liquid outlet pipe 54 are also placed in the chassis body 1. The liquid inlet pipe 53 is connected to the liquid inlet ends of several liquid cooling pipes 52, and the liquid outlet pipe 54 is connected to the liquid outlet ends of several liquid cooling pipes 52. One end of the liquid inlet pipe 53 and the liquid outlet pipe 54 both extend out of the chassis body 1 and are connected to an external liquid cooling device. Preferably, the coolant used in the external liquid cooling device is a fluorinated liquid, which is non-conductive and will not cause damage to electronic components.

[0030] Specifically, when the server hardware is running, the heat generated is first transferred to the base plate 5, and the base plate 5 then transfers the heat to the liquid cooling pipe 52 in the liquid cooling tank 51. Since the liquid cooling pipe 52 is in close contact with the base plate 5, it can absorb the heat quickly and effectively. Subsequently, the coolant in the liquid cooling tank 51 will absorb the heat and take it out of the chassis body 1 through the liquid outlet pipe 54, and send it back to the external liquid cooling device for cooling treatment. The cooled coolant enters the chassis again through the liquid inlet pipe 53 and continues to be recycled, forming an efficient cooling cycle process.

[0031] In this embodiment, the push-pull assembly 3 includes a symmetrically arranged support frame 1 31, a support frame 2 32 and a connecting member 33. A number of corresponding guide holes 34 are provided on the support frame 1 31 and the support frame 2 32. The corresponding guide holes 34 on each side are slidably connected to a guide rod 35. One end of each two horizontally corresponding guide rods 35 is cooperated with and installed with a front plate 36. By pulling the front plate 36, it can be pulled out. The other ends of the several guide rods 35 on both sides are respectively connected by the connecting member 33, so that the several guide rods 35 will move synchronously. When one front plate 36 is pulled out, the other front plates 36 will also move together with the front plate 36.

[0032] In this embodiment, a connecting lock hole 21 is provided at the end of the guide frame 2 and the connecting member 33. The bolt is threadedly connected to the lock hole 21 to lock the connecting member 33 and the guide frame 2 to prevent accidental collision from causing the push-pull component 3 to slip out, resulting in collision with the push-pull component 3, damaging the push-pull component 3 and causing personal injury.

[0033] In this embodiment, a plurality of upwardly curved arc-shaped protrusions 361 are symmetrically provided on the front plate 36 , and a pull ring 362 is passed through each of the arc-shaped protrusions 361 . By grabbing the pull ring 362 , the push-pull assembly 3 can be easily pulled out.

[0034] In order to prevent the push-pull component 3 from hitting the bottom plate 5 due to excessive force when being pushed inward, at least two obliquely arranged buffer blocks 363 are provided on the arc-shaped edge on the inner side of the front plate 36. The buffer blocks 363 abut the front end edge of the bottom plate 5. When the front plate 36 is pushed inward until the buffer blocks 363 abut against the bottom plate 5, the buffer blocks 363 will first contact the bottom plate 5, and the buffer blocks 363 will be offset at an angle upward, thereby playing a buffering role and avoiding damage caused by hard impact.

[0035] In this embodiment, the chassis body 1 includes an outer shell 11 and an L-shaped back cover 12. The outer shell 11 and the back cover 12 are hinged by a hinge. The outer shell 11 is located on one side of the back cover 12 and is provided with a plurality of inwardly bent mounting blocks 13. The back cover 12 and the mounting block 13 are provided with a connected lock hole 2 14. The bolt is threadedly connected to the lock hole 2 14 to lock the rear end of the chassis body 1 closed to prevent a large amount of dust from entering the interior of the chassis body 1. The top of the outer shell 11 is bent inward and is located below the back cover 12 to support the back cover 12.
