Description

Technical Field

[0001] This invention belongs to the field of liquid cooling heat dissipation accessories technology, specifically a cold plate type liquid cooling heat sink and its installation fixture. Background Technology

[0002] As a node in a network, a server stores and processes 80% of the data and information on the network. It is similar in composition to a general computer case, including a processor, hard drive, memory, system bus, etc.

[0003] The need for multimedia streaming, cloud storage, data mining, analytics, and machine learning applications has driven the demand for high-performance computing solutions, leading to an increase in the number of CPUs and GPUs in servers to improve processor speed. Given the limited size of servers and the numerous high-power electronic components operating under heavy loads for extended periods, the ability to promptly dissipate the heat generated by these components directly impacts the stability of server operation.

[0004] There are many types of CPU coolers available today, but the most common are air cooling and liquid cooling. Liquid cooling works by using a pump to circulate coolant, carrying away heat from the CPU. Air cooling, on the other hand, uses a fan to dissipate heat from the heatsink or heat pipes into the air, and then the airflow design carries the heat outside the computer, achieving cooling. Liquid cooling offers advantages such as quiet operation, stable cooling, and less dependence on environmental conditions. It directly extracts heat, preventing it from accumulating inside the computer case. Air cooling tends to be noisier because it dissipates heat through the airflow generated by the fan.

[0005] Air coolers can cause significant thermal fluctuations when the CPU is under high load, which can easily lead to exceeding the CPU's temperature warning range and causing it to throttle. In contrast, water cooling systems have a larger heat capacity and therefore exhibit much smaller thermal fluctuations.

[0006] Cold plate liquid cooling radiators are increasingly used in servers due to their excellent heat dissipation performance and flexible structure. They typically consist of a cold plate, tubing, and quick connectors. For dual-socket motherboards with two CPUs, two cold plates are usually required, connected by tubing to form a loop. The entire liquid cooling module cannot be installed and removed by one person; it usually requires two people working together: one to hold the cold plate and the other to hold the quick connectors and support the tubing. This ties up two people, reducing installation efficiency and increasing labor costs. There is an urgent need to solve the problem of ease of installation for liquid cooling modules, enabling single-person operation. Furthermore, existing cold plates and liquid cooling pipes have limited heat dissipation capacity for the CPU, mainly due to their small contact area. Summary of the Invention

[0007] To address the problem that the contact area between the liquid cooling pipes, cold plate, and CPU is small, and that the two cold plates and liquid cooling pipes are inconvenient to move and operate, this invention provides a cold plate type liquid cooling radiator and its installation fixture.

[0008] This invention is achieved through the following technical solution:

[0009] A cold plate type liquid cooling heat sink includes two cold plate bodies mounted on a PCB board and corresponding to two CPUs respectively. The cold plate bodies are provided with liquid cooling pipes, and quick connectors are provided at both ends of the liquid cooling pipes. A fixed bracket covering the outside of the liquid cooling pipes is installed on the top surface of the cold plate bodies. The fixed bracket is provided with a protrusion that can limit the direction of the liquid cooling pipes.

[0010] Two cold plates are respectively set up to correspond to two CPUs. Two cold plates are connected in series on a liquid cooling pipe and connected to the cold source through a quick connector at the end. The fixed bracket holds the liquid cooling pipe tightly on the cold plate and limits the direction of the liquid cooling pipe and the cold plate through the protrusion to ensure and improve the heat dissipation effect.

[0011] A further improvement of the present invention is that at least two protrusions are provided, and the at least two protrusions are staggered on both sides of the liquid cooling pipe's passage path. The staggered distribution of two protrusions on the same fixed bracket allows the liquid cooling pipe to bypass the two protrusions successively when passing between the fixed bracket and the cold plate body. This creates a bending shape on the cold plate body, effectively increasing the contact area between the liquid cooling pipe and the cold plate body, and improving the CPU heat dissipation effect.

[0012] A further improvement of the present invention is that the protrusion is formed by downward stamping. Direct stamping of the fixed bracket facilitates the improvement of the processing and forming of the protrusion.

[0013] A further improvement of the present invention is that the aforementioned cold plate body is provided with a contact portion that mates with the CPU and is raised upwards. The raised contact portion that mates with the CPU can help to accurately locate the mounting position of the cold plate body on the PCB board; at the same time, due to the raised structure of the contact portion, the contact area between the side of the CPU and the cold plate body can also be increased, thereby improving the heat dissipation efficiency of the CPU.

[0014] A further improvement of the present invention is that the aforementioned fixed bracket is provided with a locking part that allows it to be connected and moved. The locking part connects to the fixed bracket, thereby increasing the stability and ease of movement during operation.

[0015] A mounting fixture for a cold-plate liquid-cooled radiator includes a connecting plate and a cold-plate liquid-cooled radiator. The connecting plate has locking parts at both ends that engage with snap-fit ​​parts. By connecting the locking parts on the connecting plate with the snap-fit ​​parts, two cold-plate liquid-cooled radiators can form a rigid support connection through the connecting plate. This allows for simultaneous movement of both radiators by operating only one connecting plate, improving the ease of operation.

[0016] A further improvement of the present invention is that the connecting plate has grooves at both ends, and a sliding plate slides within the grooves. A locking part is disposed on the sliding plate. The sliding plate is also provided with a set screw that can lock the sliding plate in the groove. The sliding plate can be adjusted in position within the groove on the connecting plate according to the specific position of the two cold plate liquid coolers on the PCB board, thereby adjusting the distance between the two sliding plates on the connecting plate to match the distance between the two cold plate liquid coolers. Then, the locking part on the sliding plate is engaged with the snap-fit ​​part on the fixing bracket. Finally, the sliding plate bolt is tightened in the groove of the connecting plate by the set screw, preventing the two cold plate liquid coolers from moving randomly on the connecting plate during the operation of moving the cold plate liquid coolers, thus maintaining their stability.

[0017] A further improvement of the present invention is that a positioning fold is provided on one side of the two sliding plates facing away from each other; and a positioning groove that mates with the positioning fold is provided on at least one side of the fixed bracket. The positioning fold cooperates with the positioning groove on the fixed bracket to form a pre-corresponding adjustment prompt between the adjusting sliding plate and the fixed bracket, thereby serving as an auxiliary mark and facilitating the alignment of the locking part and the snap-fit ​​part.

[0018] A further improvement of the present invention is that each of the two opposing ends of the slide grooves is provided with a scale line for measuring the position of the slide plate within the slide groove. By comparing the slide plate with the scale line during the adjustment operation, precise distance control of the slide plate within the slide groove of the connecting plate can be achieved.

[0019] A further improvement of the present invention is that the connecting plate is provided with a handle in the middle for easy picking and placing. The handle located in the middle of the connecting plate facilitates the lifting and operation of the connecting plate, while leaving an operable gap space between the handle and the connecting plate, thus improving the convenience of operation.

[0020] As can be seen from the above technical solutions, the beneficial effects of the present invention are: 1. Two cold plate bodies are respectively set to correspond to two CPUs, and two cold plate bodies are connected in series on a liquid cooling pipe and connected to the cold source through a quick connector at the end; 2. The fixed bracket holds the liquid cooling pipe tightly on the cold plate body, and the protrusion limits the direction of the liquid cooling pipe and the cold plate body to ensure and improve the heat dissipation effect.

Detailed Implementation

[0028] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] As attached Figure 1-5 As shown, a mounting fixture for a cold plate liquid-cooled radiator includes a connecting plate 500 and cold plate liquid-cooled radiators respectively disposed at both ends of the connecting plate 500. The connecting plate 500 provides a rigid connection between the cold plate radiators, enabling simultaneous operation and movement of two cold plate radiators via the connecting plate 500.

[0030] The connecting plate 500 has a handle 510 in the middle for easy handling. The handle 510 in the middle of the connecting plate 500 facilitates lifting and operation of the connecting plate 500, while leaving an operable gap between the handle 510 and the connecting plate 500, thus improving the convenience of operation.

[0031] The connecting plate 500 has sliding grooves 520 at both ends, and a sliding plate 530 slides within the sliding grooves 520. The sliding plate 530 has a locking part 531 that connects to the cold plate liquid cooler. The sliding plate 530 also has a set screw 532 that locks it within the sliding groove 520. The sliding plate 530 can be adjusted within the sliding groove 520 of the connecting plate 500 according to the specific positions of the two cold plate liquid coolers on the PCB board, thereby adjusting the distance between the two sliding plates 530 on the connecting plate 500 to match the spacing of the two cold plate liquid coolers. Then, the locking part 531 on the sliding plate 530 engages with the snap-fit ​​part 220 on the fixing bracket 200. Finally, the set screw 532 bolts the sliding plate 530 into the sliding groove 520 of the connecting plate 500, preventing the two cold plate liquid coolers from moving randomly on the connecting plate 500 during operation, thus maintaining its stability.

[0032] The cold plate heatsink includes two cold plate bodies 100 mounted on a PCB board and corresponding to two CPUs respectively. Each cold plate body 100 has a liquid cooling pipe 300, with quick connectors 400 at both ends. A fixing bracket 200 covering the liquid cooling pipe 300 is mounted on the top surface of each cold plate body 100, and the fixing bracket 200 has a protrusion 210 that limits the direction of the liquid cooling pipe 300. The two cold plate bodies 100 are respectively positioned corresponding to the two CPUs. Two cold plate bodies 100 are connected in series on a single liquid cooling pipe 300 and connected to a cold source via the quick connectors 400 at the ends. The fixing bracket 200 secures the liquid cooling pipe 300 to the cold plate body 100 and limits the direction of the liquid cooling pipe 300 and the cold plate body 100 through the protrusion 210, thereby ensuring and improving heat dissipation.

[0033] The fixed bracket 200 has an overall π-shaped structure. The upward-protruding part of the fixed bracket 200 cooperates with the cold plate body 100 to make room for the liquid cooling pipe 300 to pass through. The fixed bracket 200 has fixing holes on its two folded edges. The fixed bracket 200 is fixedly installed on the cold plate body 100 by screws passing through the fixing holes.

[0034] The cold plate body 100 is provided with a contact portion 110 that cooperates with the CPU and is raised upwards. The raised contact portion 110 that cooperates with the CPU can help to accurately locate the mounting position of the cold plate body 100 on the PCB board; at the same time, due to the raised structure of the contact portion 110, it can also increase the contact area between the side of the CPU and the cold plate body 100, thereby improving the heat dissipation efficiency of the CPU.

[0035] At least two protrusions 210 are provided, and the at least two protrusions 210 are staggered on both sides of the path through which the liquid cooling pipe 300 passes. The staggered distribution of two protrusions 210 on the same fixed bracket 200 causes the liquid cooling pipe 300 to bypass the two protrusions 210 successively when passing between the fixed bracket 200 and the cold plate body 100. The liquid cooling pipe 300 forms a bent shape on the cold plate body 100, which effectively increases the contact area between the liquid cooling pipe 300 and the cold plate body 100 and improves the heat dissipation effect on the CPU.

[0036] The protrusion 210 is formed by downward stamping. It is directly stamped onto the fixed bracket 200 to facilitate the processing and forming of the protrusion 210.

[0037] The fixed bracket 200 is provided with a snap-fit ​​part 220 that can be connected to it for movement and can cooperate with the locking part 531. The snap-fit ​​part 220 is connected to the fixed bracket 200 to increase the firmness when moving the fixed bracket 200, thereby improving the stability and convenience of the movement operation.

[0038] The two sliding plates 530 are provided with positioning flanges 533 on opposite sides; at least one side of the fixed bracket 200 is provided with positioning grooves 230 that cooperate with the positioning flanges 533. The positioning flanges 533 cooperate with the positioning grooves 230 on the fixed bracket 200 to form a pre-corresponding adjustment prompt between the sliding plate 530 and the fixed bracket 200, which serves as an auxiliary mark and facilitates the alignment of the locking part 531 and the snap-fit ​​part 220.

[0039] The locking part 531 on the connecting plate 500 is connected to the snap-fit ​​part 220, so that the two cold plate liquid cooling radiators can form a rigid support connection through the connecting plate 500. This allows the two cold plate liquid cooling radiators to be moved together by operating one connecting plate 500, thus improving the ease of operation of the two cold plate liquid cooling radiators.

[0040] Both of the aforementioned slide grooves 520 have scale lines 540 on their outer sides at opposite ends, which can measure the position of the slide plate 530 within the slide groove 520. By comparing the slide plate 530 with the scale lines 540 during the adjustment operation, precise distance control of the slide plate 530 within the slide groove 520 of the connecting plate 500 can be achieved.

[0041] The connecting plate 500 has a groove 520 with a slot through which the locking part 531 and the set screw 532 pass. To improve the structure of the connecting plate 500 corresponding to the groove 520 section, the slot can be partitioned to reduce the area occupied by the slot in the groove 520 of the connecting plate 500.

[0042] To facilitate the installation of the positioning fold 533 on the slide plate 530 into the slide groove 520, the slot can be connected to the outside of the connecting plate 500 to facilitate the placement and removal of the slide plate 530 into the slide groove 520.

[0043] The locking part 531 is specifically a locking screw, and the snap-fit ​​part 220 is a quick-lock screw clip that can cooperate with the locking screw. The threaded connection structure improves the connection strength between the slide plate 530 and the fixed bracket 200, avoiding the risk of slippage during movement and damage to components on the PCB board.

[0044] The two quick connectors 400 are fitted together with a support plate 410. The support plate 410 fixes the two quick connectors 400, which facilitates the connection of the two quick connectors 400 to the cold source. It can also cooperate with the connecting plate 500 to allow one hand to operate the handle 510 and the other hand to operate the support plate 410, thus completing the convenient operation of moving the cold plate radiator.

[0045] The present invention discloses a cold plate type liquid cooling radiator and its mounting fixture, wherein two cold plate bodies 100 are respectively set corresponding to two CPUs, and two cold plate bodies 100 are connected in series on a liquid cooling pipe 300 and connected to a cold source through a quick connector 400 at the end; a fixing bracket 200 holds the liquid cooling pipe 300 tightly on the cold plate body 100, and limits the direction of the liquid cooling pipe 300 and the cold plate body 100 by a protrusion 210 to ensure and improve the heat dissipation effect.
