[0034] Reference below Figure 1-Figure 4 The invention describes a liquid cooling plate anti-leakage liquid collecting tank structure according to an embodiment of the invention.

[0035] like Figure 1-Figure 4 As shown, the liquid cooling plate anti-leakage liquid collecting tank structure is mainly used at the processor position of the motherboard to remove the heat of the processor by liquid cooling. The liquid cooling plate anti-leakage liquid collecting tank structure includes a cold plate base 100, a cooling assembly 200 and a leakage line 330. Specifically, the cold plate base 100 is installed on the motherboard, and a mounting groove 110 is provided in the middle of the cold plate base 100. The mounting groove 110 is a hollow area in the middle of the cold plate base 100, and the processor of the motherboard is located in the mounting groove 110.

[0036] The cooling assembly 200 is detachably connected to the cold plate base 100, and the bottom of the cooling assembly 200 covers the chip surface of the mainboard, that is, covers the surface of the mainboard processor. The cooling assembly 200 includes a cold plate bottom plate 210 and a cold plate upper cover 220 that are sealed and connected, and the cold plate upper cover 220 is connected to a water nozzle 320. The cold plate bottom plate 210 and the cold plate upper cover 220 are sealed and connected by welding, the cold plate bottom plate 210 covers the surface of the processor, and the cold plate upper cover 220 is connected to the water nozzle 320, and the liquid cooling medium enters the cooling assembly 200 from the water nozzle 320 to absorb the heat of the processor and is discharged from another water nozzle 320.

[0037] The faucet 320 and the upper cover 220 of the cold plate are two independent parts, which need to be brazed later to achieve an integrated structure. The welding position has the risk of unstable welding quality or aging leakage after long-term use. The existing practice is to arrange a leakage line 330 on the surface of the cold plate upper cover 220 for detection and leakage alarm. However, the leakage line 330 can only trigger an alarm when it contacts liquid, and the direction of liquid leakage at the connection between the faucet 320 and the upper cover 220 of the cold plate is uncontrollable, and the leaked liquid cannot contact the leakage line 330 in time and trigger the alarm. In addition, the leaked liquid will flow along the surface to other components of the mainboard, causing damage to the components of the mainboard.

[0038] In this embodiment, a barrier 231 is provided on the periphery of the cold plate upper cover 220, the barrier 231 surrounds the periphery of the water nozzle 320 to form a liquid collection groove 230 and extends upward from the surface of the cold plate upper cover 220. A liquid leakage line 330 is provided in the barrier 231, and the liquid leakage line 330 is used to detect the liquid in the liquid collection groove 230.

[0039] Specifically, the leaked liquid will accumulate in the liquid collection tank 230. When the liquid in the liquid collection tank 230 contacts the liquid leakage line 330, the liquid leakage line 330 will sound an alarm. Since the liquid is confined in the liquid collection tank 230, and the liquid leakage line 330 is also arranged in the liquid collection tank 230, the probability of the liquid leakage line 330 contacting the liquid is increased, thereby improving the detection sensitivity of the liquid leakage line 330. The enclosure 231 is higher than the surface of the upper cover 220 of the cold plate. When the cooling assembly 200 is in a horizontal layout, the liquid leaked from the faucet 320 will accumulate in the liquid collection tank 230, effectively preventing the liquid from flowing to the components of the mainboard. The server usually adopts a horizontal layout. The liquid collection tank 230 of the utility model can effectively solve the problems of liquid leakage detection sensitivity and temporary storage of liquid leakage in the horizontally arranged server.

[0040] The leakage line 330 is a technical solution well known to those skilled in the art, and the working principle and structure of the leakage line 330 are not described in detail in this embodiment. The utility model mainly improves the detection sensitivity of the leakage line 330 and the temporary storage of leakage to avoid damage to the mainboard components.

[0041] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the cold plate upper cover 220 and the enclosure 231 are integrally formed. Specifically, the cold plate upper cover 220 and the enclosure 231 are integrally formed by forging, and there is no connection gap between the cold plate upper cover 220 and the enclosure 231, which effectively prevents liquid from leaking from the liquid collection tank 230.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the enclosure portion 231 extends upward perpendicularly to the surface of the cold plate upper cover 220 , and the leakage line 330 is fixed to the bottom of the liquid collection groove 230 by a line clamp 340 .

[0043] Specifically, the enclosure 231 is arranged vertically on the upper cover 220 of the cold plate, which can reduce the difficulty of production and processing, and is conducive to the mass production of the liquid cooling plate anti-leakage liquid collecting tank structure and improve the yield rate. The leakage line 330 is fixed to the bottom of the liquid collection tank 230 by the wire clamp 340. When the liquid collection tank 230 accumulates liquid, the leakage line 330 can contact the liquid in time to improve the detection sensitivity.

[0044] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the thickness of the enclosure 231 is ≥1.0 mm, so as to ensure that the wall thickness of the cold plate upper cover 220 is not too thin during forging, thereby causing damage to the liquid collection groove 230 .

[0045] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the height of the enclosing portion 231 is ≥ 2.0 mm. Specifically, in this embodiment, the height of the enclosing portion 231 is selected between 2.0 mm and 3.0 mm to ensure that the liquid storage tank 230 has enough space to store liquid when leakage occurs.

[0046] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the cooling assembly 200 is provided with a liquid cooling cavity 310, and two groups of water nozzles 320 are provided and are respectively connected to the liquid cooling cavity 310. The liquid cooling cavity 310 is composed of a cold plate bottom plate 210 and a cold plate upper cover 220. Furthermore, a leakage line 330 is arranged around the two water nozzles 320. The water nozzles 320 are respectively a liquid inlet nozzle and a liquid discharge nozzle. The liquid cooling medium of the liquid cooling pipeline enters the liquid cooling cavity 310 from the liquid inlet nozzle and is then discharged from the liquid discharge nozzle to complete the circulation of the liquid cooling medium. The leakage line 330 is arranged around the two water nozzles 320. When any water nozzle 320 leaks, the leakage line 330 can contact the leakage in time and feedback the leakage information to the staff.

[0047] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the cold plate bottom plate 210 and the cold plate base 100 are detachably connected by locking screws 350. The cold plate bottom plate 210 is welded to the cold plate upper cover 220. When leakage occurs when the cold plate upper cover 220 is connected to the water nozzle 320, the locking screws 350 can be removed to replace the cooling assembly 200, and the cold plate base 100 does not need to be replaced, thereby reducing the subsequent maintenance cost.

[0048] In some embodiments of the present invention, Figure 1-Figure 4 As shown, a buckle 370 is provided at the periphery of the cold plate base 100, and the buckle 370 is used to fix the relative position between the cold plate base 100 and the mainboard. Specifically, the buckle 370 is a technical solution well known to those skilled in the art, and will not be described in detail in this embodiment.

[0049] In some embodiments of the present invention, Figure 4 As shown, a protective cover 360 is disposed above the cold plate base 100, and the protective cover 360 is detachably connected to the cold plate base 100 and covers the cooling assembly 200. Specifically, the protective cover 360 can cover the connection between the water nozzle 320 and the cooling pipe, prevent the cooling pipe and the water nozzle 320 from being loosened due to external force, and protect the leakage line 330 and the cooling assembly 200 to a certain extent.
