Description

Technical Field

[0001] This utility model relates to the field of hardware heat dissipation technology, and in particular to a liquid cooling radiator and a CPU liquid cooling heat dissipation device. Background Technology

[0002] Computer CPUs generate a significant amount of heat during operation, and currently, there are two main cooling methods: air cooling and liquid cooling (also known as water cooling). Existing liquid cooling systems typically have the inlet and outlet nozzles located on the front of the radiator, with the inlet and outlet pipes perpendicular to the radiator and then perpendicular to the liquid block or pump. Since the liquid block and pump must be installed according to the CPU's location—and the CPU is often located on the PCB far from the front and top of the case—the existing liquid cooling system structure forces the inlet and outlet pipes to run through a large portion of the case. This results in complex piping within the case, making it prone to crossing with other components or cables, thus affecting the efficient use of case space. Furthermore, it significantly obstructs the view, failing to meet the optimal visual experience sought by DIY enthusiasts.

[0003] Those working in this field are considering and want to improve this problem. Current improvement proposals include:

[0020] This utility model also provides a CPU liquid cooling heat dissipation device, the technical solution of which is as follows:

[0021] The system includes: a liquid cooling radiator, a fan, an inlet pipe, an outlet pipe, and a liquid cooling head. The liquid cooling radiator is arranged parallel to the fan. The inlet pipe and the outlet pipe are connected to the liquid cooling radiator and the liquid cooling head, respectively.

The exchange chamber is located on one side of the liquid cooling radiator, and the inlet chamber and the outlet chamber are located on the other side.

[0031] It is worth noting that the liquid cooling radiator and liquid cooling device in this application can be applied to both integrated liquid cooling devices and split liquid cooling devices. The distinction between integrated and split liquid cooling devices is common knowledge in the field and will not be elaborated upon in this application.

[0032] Compared with the prior art, the technical solution of this application has the following advantages and effects:

[0033] 1. In existing liquid cooling radiators, the inlet and outlet ports are directly perpendicular to the radiator, causing the connected inlet and outlet pipes to extend perpendicularly to the radiator as well. This results in a natural bend within the chassis, leading to low space utilization and a poor visual appearance. Some existing improvements to liquid cooling radiators concentrate the inlet and outlet pipes at the boundary between the inlet and outlet chambers to achieve parallel alignment. However, this significantly increases flow resistance and sacrifices cooling efficiency. This application places the inlet port at the end of the inlet chamber parallel to the radiator and the outlet port at the surface of the outlet chamber perpendicular to the radiator. By redesigning the inlet and outlet paths and utilizing the flow characteristics of the liquid, this approach ensures both visual appeal and reduced flow resistance, thus guaranteeing the cooling effect of the liquid cooling radiator. The orientation of the inlet and outlet liquid cooling interfaces in this application is optimized. Furthermore, since this application adopts a 90° corner interface, the inlet and outlet liquid cooling pipes can be set parallel to the liquid cooling radiator, which significantly improves the appearance inside the chassis.

[0034] 2. On the other hand, the CPU liquid cooling device of this application can make full use of the height space of the fan, and arrange the liquid outlet connectors side by side on one side of the liquid outlet chamber parallel to the fan. Without increasing the thickness and length of the liquid cooling radiator itself, the liquid outlet pipe can be arranged parallel to the liquid cooling radiator. This allows the inlet and outlet pipes to be bent and arranged parallel to one side of the liquid cooling radiator, and then connected to the liquid cooling head by bending and overlapping. This makes only the width of one pipe visible from the user's perspective, significantly reducing the obstruction of the inlet and outlet pipes to the interior of the chassis and significantly improving the visual effect.

[0035] 3. On the other hand, the CPU liquid cooling device of this application has the inlet and outlet pipes and the connector of the liquid cooling head set at the 9 o'clock position of the liquid cooling head, so that the liquid cooling head and the entire right side space are integrated, which has a better visual integrity and completeness, and can realize efficient use of the space inside the chassis, leaving enough space for users to modify later.

[0036] 4. On the other hand, the design of the CPU liquid cooling device cover and mounting bracket in this application can, on the one hand, cover the inlet and outlet connectors of the liquid cooling radiator and some of the inlet and outlet pipes, making the overall design simpler and more visually appealing. On the other hand, it can also provide some protection for the pipes, preventing accidental contact and collisions during chassis maintenance, reducing the risk of leakage, and improving the safety and stability of the liquid cooling radiator. The mounting bracket is set on the mounting frame, allowing the inlet and outlet pipes to be securely fixed to the side of the liquid cooling radiator according to the CPU's installation position, thereby making a stable connection with the liquid cooling head and fitting the liquid cooling radiator more closely. This makes the arrangement of the inlet and outlet pipes in the chassis more orderly, further improving the visual effect and reducing space occupation.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0050] Example 1

[0051] This embodiment provides a liquid cooling radiator 1, such as Figure 1-3 As shown. The liquid cooling radiator includes an inlet chamber 12, an exchange chamber 13, an outlet chamber 14, several heat dissipation pipes 11, an inlet connector 15, and an outlet connector 16. The exchange chamber 13 is located on one side of the liquid cooling radiator 1, and the inlet chamber 12 and the outlet chamber 14 are located on the other side of the liquid cooling radiator 1. One end of each heat dissipation pipe 11 is connected to the exchange chamber 13, and the other end of each heat dissipation pipe 11 is connected to either the inlet chamber 12 or the outlet chamber 14. The inlet connector 15 is connected to the inlet chamber 12, and the outlet connector 16 is connected to the outlet chamber 14.

[0052] Since the working principle of the liquid cooling radiator and how it works with the fan to achieve cooling and with the liquid cooling block to achieve circulation are common knowledge in the field, they will not be elaborated here. The terms in this application regarding the inlet chamber, exchange chamber, outlet chamber, heat pipe, inlet connector, and outlet connector may have other names in the field. If these do not affect the correspondence with this application, the corresponding components and their functions are also common knowledge in the field and will not be elaborated here.

[0053] For easier viewing, Figure 1The diagram removes the covering portions of the liquid outlet connector 16 and the upper parts of the liquid inlet chamber 12, exchange chamber 13, and liquid outlet chamber 14 to show the internal structure of the liquid inlet chamber 12, exchange chamber 13, and liquid outlet chamber 14. The arrows indicate the approximate flow of the coolant in the liquid cooling radiator 1. After exiting from the liquid outlet end 52 of the liquid cooling head 5, the coolant enters the liquid inlet chamber 12 through the liquid inlet pipe 3 and the liquid inlet head 15, then enters the exchange chamber 13 through the heat dissipation pipe 11, and subsequently enters the liquid outlet chamber 14 through the heat dissipation pipe 11. Finally, it flows back to the liquid inlet end 51 of the liquid cooling head 5 through the liquid outlet connector 16 and the liquid outlet pipe 4. The diagram shows an integrated liquid cooling device. In a split liquid cooling device, since components such as pumps can be separately installed from the liquid cooling head, the liquid inlet pipe 3 and the liquid outlet pipe 4 can also be connected to other functional components (such as pumps) to facilitate coolant operation. Unless explicitly defined in this application, this application is not limited to an integrated liquid cooling device.

[0054] Figure 1 The arrow pointing in the outlet chamber 14 only indicates the case where the outlet connector 16 is located in the middle of the upper surface of the outlet chamber 14. If the outlet connector 16 is installed in other positions, the flow direction of the coolant in the outlet chamber 14 may be adjusted accordingly. Since the flow direction of coolant in liquid cooling devices and liquid cooling radiators is common knowledge, it will not be elaborated further.

[0055] Specifically, in this application, the inlet 151 of the liquid inlet connector 15 is oriented parallel to the extension direction of the heat dissipation pipe 11 connecting the liquid inlet chamber 12, and the outlet 161 of the liquid outlet connector 16 is oriented perpendicular to the extension direction of the heat dissipation pipe 11 connecting the liquid outlet chamber 14. By adjusting the orientations of the inlet 151 and outlet 161 to be parallel and perpendicular to the heat dissipation pipe 11, respectively, the coolant with greater impact force from the inlet pipe 3 can be loaded more smoothly into the liquid inlet chamber 12 of the liquid radiator 1, and the coolant with less impact force in the outlet chamber 14 can be more smoothly guided into the outlet pipe 4. This optimizes the arrangement structure of the inlet and outlet pipes of the liquid radiator 1, utilizes the liquid flow characteristics of the liquid inlet and outlet in the liquid cooling device, ensures both visual appeal and reduces water flow resistance, thus guaranteeing the cooling effect of the liquid radiator.

[0056] In one embodiment, both the inlet connector 15 and the outlet connector 16 are angle connectors. In a preferred embodiment, both the inlet connector 15 and the outlet connector 16 are 90° angle adapters, for example, as shown in the attached figure. Figure 1-3As shown, both the inlet connector 15 and the outlet connector 16 are L-shaped. This optimizes the orientation of the inlet and outlet interfaces, allowing the inlet and outlet pipes to be arranged parallel to the liquid radiator, which better fits the main body of the liquid radiator 1, significantly improving the appearance inside the chassis. Unless otherwise specified in this application, this application does not limit the specific angle or shape of the inlet and outlet connectors. The manufacturing of the inlet and outlet connectors themselves, as well as how to install and connect them to the liquid radiator, are common knowledge in the art. For example, the inlet and outlet connectors can be fixed to the inlet or outlet chamber by conventional connection methods such as bolts or welding (e.g., brazing), which are not limited here and will not be further elaborated.

[0057] In one embodiment, the liquid inlet connector 15 is installed on one end face of the liquid inlet chamber 12, which is parallel to the extending direction of the heat dissipation pipe 11 connecting the liquid inlet chamber 12. The liquid outlet connector 16 is installed on one side of the liquid outlet chamber 14, which is perpendicular to the extending direction of the heat dissipation pipe 11 connecting the liquid outlet chamber 14. For example, it can be as follows: Figure 1 As shown, the liquid outlet connector 16 is located on the upper or lower surface of the liquid outlet chamber 14, which is parallel to the paper surface, or on the right side surface, which is perpendicular to the paper surface. Furthermore, the liquid outlet connector 16 is installed in the middle of this surface.

[0058] In one embodiment, the inlet chamber 12 and the outlet chamber 14 are arranged adjacent to each other, and a partition 17 is provided between them. The exchange chamber 13, the inlet chamber 12, and the outlet chamber 14 are all cuboids.

[0059] In one embodiment, the long sides of the exchange chamber 13, the liquid inlet chamber 12 and the liquid outlet chamber 14 are all perpendicular to the extension direction of the heat dissipation pipe 11 that communicates with the exchange chamber.

[0060] In one embodiment, the number of heat dissipation pipes 11 communicating with the liquid inlet chamber 12 and the number of heat dissipation pipes 11 communicating with the liquid outlet chamber 14 in the liquid radiator are the same, as shown in the attached figure. Figure 1 The display shows that there are 6 heat dissipation pipes 11 in each chamber, or the two numbers can be the same or other values. Of course, in other embodiments, the two numbers can differ to achieve a special function, such as having more heat dissipation pipes connected to the liquid inlet chamber than to the liquid outlet chamber. Specifically, there can be 7 heat dissipation pipes 11 connected to the liquid inlet chamber 12 and 5 heat dissipation pipes 11 connected to the liquid outlet chamber 14, which makes the liquid outflow from the liquid inlet chamber smoother and further improves performance.

[0061] As one embodiment, heat sinks 111 are provided on both sides of the heat pipe 11. As a common choice, the heat sink 111 can be a heat sink fin, such as a commonly used fin, or other types of heat sinks.

[0062] In one embodiment, the plurality of heat dissipation pipes 11 and the heat dissipation component 111 are integrally formed into a cuboid. Support frames are provided on both sides of the long side of the cuboid formed by the plurality of heat dissipation pipes 11 and the heat dissipation component 111. These support frames are used to connect the liquid inlet chamber 12, the exchange chamber 13, and the liquid outlet chamber 14 into a whole. Regarding the connection and fixing of the support frame to each component (e.g....) Figure 1-3 As shown, the selection of materials, size matching, and connection matching of other components (such as screw connection, connector, and integral connection) are all common knowledge in this field. The specific installation and assembly processes are also common knowledge in this field and will not be elaborated here.

[0063] Example 2

[0064] This embodiment provides a CPU liquid cooling device, such as... Figure 4-8 As shown, it includes: a liquid cooling radiator 1, a fan 2, a liquid inlet pipe 3, a liquid outlet pipe 4, and a liquid cooling head 5. The liquid cooling radiator 1 is arranged parallel to the fan 2. The two ends of the liquid inlet pipe 3 and the liquid outlet pipe 4 are respectively connected to the liquid cooling radiator 1 and the liquid cooling head 5. The selection of the fan 2, the liquid inlet pipe 3, the liquid outlet pipe 4, and the liquid cooling head 5 are all existing technologies. The number and specifications of the fan 2 can also be selected according to actual conditions, and the material and size of the liquid inlet and outlet pipes can also be selected according to actual conditions. The liquid cooling head 5 can be suitable for integrated liquid cooling heat dissipation devices or adapted to split liquid cooling heat dissipation devices. Unless explicitly defined in this application, this application does not particularly limit the selection of the corresponding components.

[0065] The liquid cooling radiator 1 includes an inlet chamber 12, an exchange chamber 13, an outlet chamber 14, several heat dissipation pipes 11, an inlet connector 15, and an outlet connector 16. The exchange chamber 13 is located on one side of the liquid cooling radiator 1, and the inlet chamber 12 and the outlet chamber 14 are located on the other side. One end of each heat dissipation pipe 11 is connected to the exchange chamber 13, and the other end is connected to either the inlet chamber 12 or the outlet chamber 14. The inlet connector 15 is connected to the inlet chamber 12, and the outlet connector 16 is connected to the outlet chamber 14. The inlet port 151 of the inlet connector 15 is parallel to the extension direction of the heat dissipation pipe 11 connecting to the inlet chamber 12, and the outlet port 161 of the outlet connector 16 is perpendicular to the extension direction of the heat dissipation pipe 11 connecting to the outlet chamber 14. One end of each inlet pipe 3 is connected to the inlet port 151, and the other end is connected to the outlet end 52 of the liquid cooling head 5. One end of the liquid outlet pipe 4 is connected to the liquid outlet 161, and the other end is connected to the liquid inlet 51 of the liquid cooling head 5. The attached figure shows the case of an integrated liquid cooling device. In a split liquid cooling device, since components such as pumps can be set separately from the liquid cooling head, in order to realize the operation of coolant, the liquid inlet pipe 3 and the liquid outlet pipe 4 can also be connected to other functional components, such as pumps. Unless there is an explicit feature limitation in this application, this application is not limited to an integrated liquid cooling device.

[0066] The connection and sealing of the inlet pipe, outlet pipe, inlet connector, outlet head, inlet end, and outlet end are common knowledge in the field. The specific structure of the connector can also be implemented in different forms, as long as it can achieve connection and basic sealing to prevent leakage. Unless explicitly defined in this application, this application is not limited to the corresponding connection and sealing structure.

[0067] In one embodiment, both the liquid inlet connector 15 and the liquid outlet connector 16 are 90° angled adapters. The liquid inlet connector 15 is installed on one end face of the liquid inlet chamber 12, and this end face is parallel to the extension direction of the heat dissipation pipe 11 connecting the liquid inlet chamber 12. The liquid outlet connector 16 is installed on one side of the liquid outlet chamber 14, and this side is perpendicular to the extension direction of the heat dissipation pipe 11 connecting the liquid outlet chamber 14, and this side is parallel to the mounting surface of the fan 2. The liquid outlet connector 16 and the fan 2 are located on the same side of the liquid cooling radiator 1.

[0068] Additionally, it should be noted that the liquid cooling radiator 1 can be selected from the liquid cooling radiator mentioned in Example 1, and can be used as the liquid cooling radiator in Example 2.

[0069] As one embodiment, such as Figure 4-6As shown, one end of the liquid inlet pipe 3 is connected to the liquid inlet 151, and after a 90° bend, the other end is connected to the liquid outlet 52 of the liquid cooling head 5. One end of the liquid outlet pipe 4 is connected to the liquid outlet 161, and after two 90° bends, the other end is connected to the liquid inlet 51 of the liquid cooling head 5. This fully utilizes the height space of the fan 2, allowing the liquid outlet connectors 16 to be arranged side-by-side on one side of the liquid outlet chamber 14 parallel to the fan 2. Without increasing the thickness and length of the liquid cooling radiator 1, the liquid outlet pipe 3 can be arranged parallel to the liquid cooling radiator 1. Figure 8 As shown, the inlet and outlet liquid pipes can be bent and arranged parallel to one side of the liquid cooling radiator 1, and then connected to the liquid cooling head by overlapping each other through bending. This ensures that only the width of one pipe is visible from the user's perspective, significantly reducing the obstruction of the inlet and outlet liquid pipes to the interior of the chassis and significantly improving the visual effect.

[0070] Example 3

[0071] This embodiment, based on Embodiment 2, provides a CPU liquid cooling heat dissipation device, such as... Figure 6-8 As shown, the details are as follows:

[0072] One end of the liquid inlet pipe 3 is connected to the liquid inlet 151. After a 90° bend, the direction of the liquid inlet pipe 3 is parallel to the extension direction of the heat dissipation pipe 11 connecting to the liquid inlet chamber 12. One end of the liquid outlet pipe 4 is connected to the liquid outlet 161. After two 90° bends, the direction of the liquid outlet pipe 4 is parallel to the extension direction of the heat dissipation pipe 11 connecting to the liquid inlet chamber 12. That is, the directions of the liquid inlet pipe 3 and the liquid outlet pipe 4 are both parallel to the liquid cooling radiator, which can be hidden behind the liquid cooling radiator 1 and the fan 2, thus greatly reducing the space occupied in the chassis and greatly increasing the continuous visible space in the chassis.

[0073] In one embodiment, the liquid cooling radiator 1 is also provided with a fixing bracket 19 for fixing the liquid inlet pipe 3 and the liquid outlet pipe 4.

[0074] In one embodiment, a cover 18 is provided outside the liquid inlet chamber 12 and the liquid outlet chamber 14, and the top height of the cover 18 is not higher than the top height of the fan.

[0075] The enclosure and mounting brackets serve several purposes. First, they conceal the liquid radiator's inlet and outlet connectors and some of its pipes, resulting in a cleaner overall look and better visual appeal. Second, they protect the pipes, preventing accidental contact and damage during chassis maintenance, thus reducing the risk of leakage and improving the radiator's safety and stability. The mounting brackets, mounted on the mounting frame, securely fix the inlet and outlet pipes to the side of the radiator according to the CPU's mounting position, ensuring a stable connection with the liquid head and a closer fit to the radiator. This results in a neater arrangement of the inlet and outlet pipes within the chassis, further enhancing the visual appeal and reducing space requirements.

[0076] As one implementation method, such as Figure 8 As shown, the liquid cooling head 5 is mounted on the PCB (also known as the motherboard) inside the chassis to cool the CPU on the PCB. The liquid cooling system is positioned from a user's vertical viewing angle after installation in the chassis, with the inlet 51 and outlet 52 located at the 9 o'clock position of the liquid cooling head 5. The inlet and outlet pipes' connectors to the liquid cooling head are positioned at the 9 o'clock position, making the liquid cooling head and its entire right-side space within the chassis appear as a unified whole. This improves visual integrity and allows for efficient use of chassis space, providing ample room for future modifications.

[0077] In one embodiment, the inlet end 51 and the outlet end 52 are arranged vertically, with the inlet end 51 located below the outlet end 52. Figure 8 As shown, this arrangement ensures that, from the user's vertical viewing direction, the inlet pipe is always above the outlet pipe throughout the entire connection process from the liquid cooling head to the liquid cooling radiator, with only one pipe appearing in the user's line of sight, resulting in a simpler overall design and better visual effect. It should also be noted that the liquid cooling radiator 1 can be the same as the one mentioned in Example 1, used as the liquid cooling radiator in Example 3.

[0078] Example 4

[0079] This embodiment, based on Embodiment 2, provides a CPU liquid cooling heat dissipation device, such as... Figure 6-8 As shown, the details are as follows:

[0080] The inlet chamber 12 and the outlet chamber 14 are arranged adjacent to each other, and a partition 17 is provided between them. The exchange chamber 13, the inlet chamber 12, and the outlet chamber 14 are all cuboids. The long sides of the exchange chamber 13, the inlet chamber 12, and the outlet chamber 14 are perpendicular to the extension direction of the heat dissipation pipe 11 that communicates with the exchange chamber. The outlet connector 16 is installed in the middle of this surface. The number of heat dissipation pipes 11 that communicate with the inlet chamber 12 is the same as the number of heat dissipation pipes 11 that communicate with the outlet chamber 14. Heat dissipation components 111 are provided on both sides of the heat dissipation pipe 11. The heat dissipation components 111 are heat dissipation fins. The plurality of heat dissipation pipes 11 and the heat dissipation components 111 are formed as a whole into a cuboid. Support frames are provided on both sides of the long side of the cuboid formed by the plurality of heat dissipation pipes 11 and the heat dissipation components 111. The support frames are used to connect the inlet chamber 12, the exchange chamber 13, and the outlet chamber 14 into a whole. Additionally, it should be noted that the liquid cooling radiator 1 can be selected from the liquid cooling radiator mentioned in Example 1, which can be used as the liquid cooling radiator in Example 4.
