Description

Technical Field

[0001] This utility model relates to a liquid-cooled cabinet, whose IPC classification number is H05K 7 / 20(2006.01). Background Technology

[0002] Existing server racks typically use air cooling or liquid cooling to dissipate heat from their internal electrical components. Air-cooled racks usually use fans to extract heat from the rack, and the rack needs to have air intake and exhaust vents. However, they have poor dust protection and low heat dissipation efficiency, making them unsuitable for use with high-power electrical components or in harsh external environments. Liquid-cooled racks, while offering higher heat dissipation efficiency and better protection, require a large number of connecting pipes inside the rack. When these connecting pipes break or accumulate a large amount of condensation, water can splash or fall onto the electrical components, causing damage. Therefore, there is a need for improvement. Utility Model Content

[0003] To solve the above problems, this utility model provides the following technical solution:

[0004] A liquid-cooled cabinet includes a housing, a frame disposed within the housing, a radiator, and a cooling device. The cabinet is characterized by further including a tubular sleeve and a partition portion vertically fixed within the housing, separating the radiator from the cooling device. The radiator is located radially to one side of the partition portion. The partition portion has a through hole. The sleeve extends through the through hole of the partition portion to the radiator, and the radiator's inlet and outlet are fitted into the sleeve's tubular cavity. The radiator's inlet and outlet are connected to the cooling device via connecting pipes passing through the sleeve.

[0005] This utility model of a liquid-cooled cabinet uses partitions and sleeves to isolate the cooling device and connecting pipes from the electrical components installed inside the cabinet, while simultaneously providing liquid cooling for the electrical components. This reduces the likelihood of condensate or leaked water from the connecting pipes or cooling device falling onto the electrical components and causing damage, thus improving the cabinet's operational stability while also ensuring its heat dissipation performance.

[0006] Furthermore, the frame includes a first mounting bracket and a second mounting bracket located on both sides, and the outer frames of the first mounting bracket and the second mounting bracket are respectively assembled by splicing folded plates.

[0007] Furthermore, the folding plate includes a first folding plate, a second folding plate, a third folding plate, and a fourth folding plate formed by bending one end of the first folding plate counterclockwise, a fifth folding plate formed by bending one end of the fourth folding plate clockwise, and a sixth folding plate formed by bending one end of the fifth folding plate counterclockwise.

[0008] Furthermore, the first fold plate is perpendicular to the second fold plate, the second fold plate is perpendicular to the third fold plate, and the fifth fold plate is perpendicular to the sixth fold plate. The angle between the third fold plate and the fourth fold plate is 'a', and the angle between the fourth fold plate and the fifth fold plate is 'b'. Then, a = b = 150°.

[0009] Furthermore, a tray is provided below the sleeve. In the axial projection of the liquid-cooled cabinet, the outline of the sleeve extension section L2 from the partition to the radiator falls within the outline of the tray's projection.

[0010] Furthermore, the partition includes a plate-shaped first baffle, a mounting top plate extending radially toward the radiator side from one axial end of the first baffle, and a plate-shaped second baffle folded upward from one end of the mounting top plate.

[0011] Furthermore, the cooling device includes a cooler fixedly installed above the mounting plate and a water pump installed below the cooler. The outlet of the water pump passes through a sleeve via a connecting pipe and leads to the inlet of the radiator. The outlet of the radiator passes through a sleeve via a connecting pipe and leads to the inlet of the cooler. The outlet of the cooler passes through a connecting pipe and leads to the inlet of the water pump.

[0012] Furthermore, the partition also includes a mounting base plate that extends radially away from the radiator side at the other axial end of the partition plate. The mounting base plate is located below the radiator's inlet and outlet, and the water pump is mounted on the mounting base plate.

[0013] Furthermore, the cooling device also includes a water tank installed on or above the mounting plate, which is connected in series between the outlet of the cooler and the inlet of the water pump via a connecting pipe.

[0014] Furthermore, the cooling device is a cooling tower installed outside the casing. The inlet of the cooling tower is connected to the outlet of the radiator through a connecting pipe, and the outlet of the cooling tower is connected to the inlet of the radiator through a connecting pipe.

[0028] Example 1:

[0029] See Figures 1 to 4This utility model discloses a liquid-cooled cabinet, including a housing 100, a frame 200 and a radiator 300 fixedly installed inside the housing 100, a cooling device 400 connected to the radiator 300 for liquid circulation, a sleeve 500, a partition 600 and a connecting pipe 800. The radiator 300 is a metal plate radiator or a finned radiator, and the radiator has a chamber or pipe for liquid flow to dissipate heat from the electrical components inside the cabinet. The sleeve 500 is tubular with open ends. The partition 600 has a through hole 670. In this invention, the frame 200 and the partition 600 are vertically installed inside the housing 100. The partition 600 separates the radiator 300 from the cooling device 400. The sleeve 500 extends through the through hole 670 of the partition to the radiator 300. The inlet and outlet of the radiator 300 are connected to the connecting pipe 800, which passes through the sleeve 500 and connects to the cooling device 400. After the liquid-cooled cabinet of this invention is assembled, the sleeve 500 accommodates the inlet and outlet of the radiator 300, as well as the extension of the connecting pipe 800 from the partition 600 to the inlet and outlet of the radiator 300 (as shown in L2 in the figure), all within the cavity of the sleeve 500.

[0030] This utility model of a liquid-cooled cabinet uses partitions and sleeves to isolate the cooling device and connecting pipes from the electrical components installed in the cabinet, while simultaneously providing liquid cooling for the electrical components. This reduces the likelihood of condensate or leaked cooling liquid from the connecting pipes or cooling device falling onto the electrical components and causing damage, ensuring the structural stability of the cabinet while also taking into account its heat dissipation performance and electrical safety.

[0031] See Figure 2 The liquid cooling mechanism of this utility model also includes a tray 700 disposed below the sleeve 500. In the axial projection of the liquid cooling cabinet, the outline of the sleeve extension L2 of the sleeve 500 from the partition 600 to the radiator 300 falls within the outline of the tray 700. This design can catch the coolant leaking from inside the sleeve and the condensate outside the sleeve, further reducing the probability of condensate or leaked coolant falling onto electrical components and causing damage, and improving the stability of the cabinet operation.

[0032] Preferably, see Figure 2 and Figure 4 The housing 100 of this utility model includes a base 160, a front panel 110, a right side panel 120, a left side panel 130, and a rear panel 140 erected around the base 160, and a top panel 150 covering the mounting cavity 10 formed by the front panel 110, right side panel 120, left side panel 130, and rear panel 140. The frame 200, heat sink 300, sleeve 500, and partition 600 are all installed within the mounting cavity 10 of the housing 100.

[0033] See Figure 5 and Figure 6 The frame 200 of this utility model includes a first mounting frame 210, a second mounting frame 220 located on both sides, and a crossbeam 230 connecting the first mounting frame 210 and the second mounting frame 220. The frames of the first mounting frame 210 and the second mounting frame 220 are respectively assembled by splicing with folding plates 20. Preferably, the first mounting frame 210 and the second mounting frame 220 are respectively welded together using folding plates 20. Of course, as in other embodiments, the first mounting frame 210 and the second mounting frame 220 are respectively connected by screws, rivets, or other fixing structures as described in mechanical engineering manuals using folding plates 20. This frame design has a simple structure and is easy to manufacture and assemble.

[0034] Furthermore, see Figure 7 The folding plate 20 of this utility model includes a first folding plate 21, and a second folding plate 22, a third folding plate 23, and a fourth folding plate 24 formed by sequentially bending one end of the first folding plate 21 in a counterclockwise direction, a fifth folding plate 25 formed by bending one end of the fourth folding plate 24 in a clockwise direction, and a sixth folding plate 26 formed by bending one end of the fifth folding plate 25 in a counterclockwise direction. The folding plate designed above has high rigidity and is relatively lightweight compared to the splicing columns of existing racks, ensuring the structural strength of the rack while reducing the overall weight of the rack. A specific embodiment is described below. Figure 8 To further enhance the load-bearing capacity of the frame, the first folding plate 21 is perpendicular to the second folding plate 22, the second folding plate 22 is perpendicular to the third folding plate 23, and the fifth folding plate 25 is perpendicular to the sixth folding plate 26. The angle between the third folding plate and the fourth folding plate is a, and the angle between the fourth folding plate 24 and the fifth folding plate 25 is b, thus satisfying a = b = 150°.

[0035] One embodiment of the cooling device 400 of this utility model is shown below. Figure 2 and Figure 11 The device includes a cooler 410 and a water pump 420. Preferably, the cooler 410 is an air-cooled cooler, which is a conventional product, such as the AH1012T-CA series air-cooled cooler. The cooler 410 of this invention is provided with a cooler inlet 411 and a cooler outlet 412, and the water pump 420 is provided with a water pump inlet 421 and a water pump outlet 422. The water pump inlet 421 is connected to the cooler outlet 412 through a connecting pipe, and the water pump outlet 422 is connected to the radiator 300 through a connecting pipe and then connected to the cooler inlet 411.

[0036] See Figure 2 and Figure 9The partition 600 of this invention includes a plate-shaped first baffle 610, a mounting top plate 620 extending radially toward the radiator 300 from one axial end of the first baffle 610, and a plate-shaped second baffle 630 folded upward from one end of the mounting top plate 620. This design fully utilizes the top space of the radiator for the arrangement of cooling devices, facilitating the installation of cooling devices within the chassis. The cooler 410 of this invention is fixedly mounted on or above the mounting top plate 620, and the water pump 420 is located axially below the cooler 410. This design allows cooled water to flow back to the water pump inlet without additional power, which helps reduce the overall energy consumption of the cabinet. Furthermore, the partition 600 of this invention also includes a mounting base plate 640 extending radially away from the radiator 300 from the other axial end of the first baffle 610. The mounting base plate 640 is located axially below the sleeve 500, and the water pump 420 is mounted on the mounting base plate 640. This design integrates the cooler into the partition, resulting in a compact overall structure and preventing damage to other electrical components in the cabinet during radiator maintenance. Furthermore, to enhance the strength of the partition 600, it also includes a left baffle 650 and a right baffle 660 disposed on both sides of the first baffle 610.

[0037] Furthermore, to increase the coolant or cooling water reserve of the cabinet and reduce the frequency of refilling, the cooling device 400 of this invention also includes a water tank 430. The water tank 430 is disposed on or above the mounting top plate 620 (e.g., mounted on the top panel), and is connected in series between the cooler outlet 412 and the water pump inlet 421 via a connecting pipe. This design increases the coolant or cooling water reserve of the cabinet, reduces the frequency of refilling, and facilitates cabinet maintenance.

[0038] Figure 10 In a preferred embodiment, the radiator 300 includes a heat dissipation body 310. Further, the heat dissipation body 310 includes a heat dissipation channel 313 disposed therein and a heat dissipation body inlet 311 and a heat dissipation body outlet 312 respectively connected to both ends of the heat dissipation channel 313.

[0039] The working principle of the liquid-cooled cabinet of this utility model is as follows: Figure 2 and Figure 3 The sleeve 500, the partition 600, and the connecting pipe 800 that connects the radiator 300, the cooling device 400, and the cooling device 400 to the radiator 300 are separated to prevent condensate or leaked coolant from splashing onto the electrical components inside the cabinet and causing damage, thus improving the stability of the liquid-cooled cabinet. The water circuit operation principle of this utility model can be found at [reference needed]. Figure 2When the liquid-cooled cabinet is working, the water pump 420 pumps the coolant through the connecting pipe to the inlet of the heat dissipation body of the radiator 300. The water is discharged from the outlet of the heat dissipation body of the radiator and flows to the inlet of the cooler 410. After being discharged from the outlet of the cooler, the water flows to the water tank 430. Then the water in the water tank 430 flows back to the inlet of the water pump 420. The water repeats the above process to continuously dissipate heat from the electrical components located on one side of the heat dissipation body 310. The liquid-cooled cabinet designed in this way is stable and has low energy consumption.

[0040] Example 2:

[0041] See Figure 12 This utility model discloses a second embodiment of a liquid-cooled cabinet. Compared with embodiment 1, this embodiment is identical in structure except for the cooling device 400 and the partition 600. In this embodiment, the cooling device 400 is a cooling tower disposed on the outside of the housing 100, and the partition 600 is a plate-shaped partition with through holes 670. After the partition 600 is installed on the housing 100, it separates the radiator 300 on one radial side. In this embodiment, the sleeve 500 also extends to the radiator 300 after passing through the through holes 670 of the partition. One end of the connecting pipe 800 is connected to the cooling tower, and the other end passes through the sleeve 500 and is connected to the inlet and outlet of the radiator 300. After assembly, the inlet and outlet of the radiator 300, as well as the third extension of the connecting pipe 800 from the partition 600 to the inlet of the radiator 300 and the fourth extension of the connecting pipe from the partition 600 to the outlet of the radiator 300, are all housed within the hollow cavity of the sleeve 500. In this embodiment, the cooling device is located outside the casing, facilitating maintenance of the cooling device.
