DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

FIG1 is a schematic diagram of the structure of a water-cooling module in a water-cooling radiator according to an embodiment of the present invention. FIG2 and FIG3 are cross-sectional views of FIG1 in different directions, respectively. In an embodiment of the present invention, the water-cooling radiator includes a plurality of water-cooling plates, and the water-cooling plates can be divided into a plurality of water-cooling modules, each of which includes at least two water-cooling plates. Furthermore, each water-cooling module includes a water inlet joint and a water outlet joint, and each water-cooling plate in the water-cooling module is connected via a sealing joint.

In one embodiment, as shown in FIG1 , the water-cooling module includes three water-cooling plates: 001 water-cooling plate, 002 water-cooling plate and 003 water-cooling plate. Among them, the 001 water-cooling plate and the 002 water-cooling plate, and the 002 water-cooling plate and the 003 water-cooling plate are connected by a sealing joint. In addition, as can be seen from FIG1 , each water-cooling module only needs to include a water inlet joint and a water outlet joint, and there is no need to set a water inlet joint and a water outlet joint on each water-cooling plate. Therefore, if a water-cooled radiator has multiple water-cooling modules, then when using a water distributor for water inlet and outlet, each water distributor only needs to be provided with the same number of through holes as the water-cooling modules. This method does not require high precision for the structural dimensions, as long as the interface dimensions between the two water-cooling plates are accurately docked, avoiding the high-precision matching dimension requirements when using one water distributor for multiple water-cooling plates. In addition, the existing screws for fixing the water cooling plate also play a role of sealing and tightening, and the number of screws required is much less than that of the existing hard connection method, thereby reducing the number of components, reducing the solution cost, and simplifying the complexity of installation.

In an embodiment of the present invention, as shown in FIG. 4 , the sealing joint is a hollow integrated structure, which is used to connect the flow channel inlets or flow channel outlets of two water-cooling plates in the same water-cooling module to achieve flow channel penetration of the water-cooling plates in each water-cooling module.

In one embodiment, the sealing joint is embedded in the flow channel inlet or the flow channel outlet of the water-cooled plate. As shown in FIG4 , grooves are provided at both ends of the sealing joint, and sealing rings are sleeved in the grooves. When the multiple water-cooled plates in each water-cooled module are connected by screws, the sealing rings are squeezed to ensure the sealing connection between the sealing joint and the flow channel inlet or the flow channel outlet. In this embodiment, the sealing joint is a separate component as shown in FIG4 , so it can be reused on different water-cooled radiators; and each water-cooled plate is also independent of each other, which is convenient for increasing or decreasing the number of water-cooled plates in the water-cooled module, and has high flexibility.

In another embodiment, one end of the sealing joint is fixed to the flow channel inlet or the flow channel outlet of a water-cooled plate in the same water-cooled module by welding, and the other end is embedded in the flow channel inlet or the flow channel outlet of another water-cooled plate in the same water-cooled module to achieve flow channel penetration of the water-cooled plates in each water-cooled module. A groove is provided at the non-welded end of the sealing joint, and a sealing ring is sleeved in the groove; when the multiple water-cooled plates in each water-cooled module are fastened and connected by screws, the sealing ring is squeezed to ensure the sealing of the connection between the sealing joint and the flow channel inlet or the flow channel outlet. In this embodiment, the sealing joint is fixed to a certain water-cooled plate by welding, so that the sealing performance is optimal, but this embodiment makes the sealing joint and the water-cooled plate become one and non-detachable, so that the use scenario of the water-cooled plate is limited and the flexibility is not high.

Of course, in another embodiment, two connection modes may exist in a water cooling module. For example, the water cooling module includes a total of 3 water cooling plates. The first water cooling plate is welded with a fixed sealing joint, and the second water cooling plate and the third water cooling plate have no sealing joints. At this time, the first water cooling plate and the second water cooling plate can be connected using the sealing joint on the first water cooling plate, and the second water cooling plate and the third water cooling plate can be connected using the sealing joint as shown in Figure 4.

FIG5 is a schematic diagram of a sealing joint embedded at a flow channel inlet or flow channel outlet in an embodiment of the present invention. In an embodiment of the present invention, the flow channel inlet or flow channel outlet of the water cooling plate is a recessed structure as shown in FIG5, which is used to accommodate one end of the sealing joint with a sealing ring. When one end of the sealing joint is embedded in the recessed structure, the sealing ring will fill the entire recessed structure, and when the fastening screws are used to tighten and screw the multiple water cooling plates, the sealing ring will be squeezed to ensure the sealing of the sealing joint and the flow channel inlet or flow channel outlet.

In the embodiment of the present invention, each water-cooling module has only one water inlet connector and one water outlet connector, regardless of the number of water-cooling plates included. However, a water-cooling radiator may include multiple groups of water-cooling modules, so a water distributor is required to achieve simultaneous water inflow. The water distributor needs to be connected to the water inlet connector and the water outlet connector of each water-cooling module, and the connection between them can be hard connection or soft connection.

Soft connection, that is, the joint of the water cooling module and the water distributor are connected by flexible pipes. This connection method reduces the requirements for structural dimensional accuracy, but the installation is more complicated, and the cost is increased by adding flexible hoses and joints.

Hard connection, that is, the joints of the water cooling module and the water distributor are connected by metal parts. This connection method is relatively simple to assemble and has low cost, but the matching accuracy of the joints of the water cooling module and the water distributor is very high. If the size accuracy of the matching surface is not enough, there will be a risk of leakage.

An embodiment of the present invention provides a hard connection implementation method. In this implementation method, the joints and the water distributor of the water cooling module are directly hard-connected with metal parts, which is simple to assemble and has high reliability. For example, the metal part can be a screw, but the present invention is not limited to this, and can also be other metal parts that realize the connection function, and the metal material can be aluminum alloy. What kind of metal part is used depends on the shape of the top of the joint of the water cooling plate. If the top is a threaded structure, the metal part can be fixedly connected with a screw. If the top of the joint is a screw structure, the metal part can be fixedly connected with a nut.

For ease of assembly, the water inlet and outlet joints of the water-cooled radiator are generally configured to be the same. These joints can be the joints in the embodiments shown in Figures 6 to 8, and the water divider can be the water divider in the embodiment shown in Figure 9. The water divider is provided with the same number of through holes as the number of water cooling modules, and does not need to correspond to the number of water cooling plates. In this way, the number of screws used in the connection method of the water cooling module of this embodiment is much smaller, thereby reducing the number of components, reducing the solution cost, and simplifying the complexity of installation.

Figure 6 is a schematic diagram of the structure of the water inlet joint and the water outlet joint of the water cooling module. As shown in Figure 6, the water inlet joint and the water outlet joint both include a threaded portion and an opening portion; the threaded portion is located at the top of the water inlet joint and the water outlet joint, and the opening portion is located at the side of the water inlet joint and the water outlet joint.

Furthermore, in the present embodiment, the opening is a through structure, which is used to enable water to flow from the water distributor to the water cooling module.

In this embodiment, the threaded portion may be an M3 thread, but the present invention does not limit the specific shape of the threaded portion, and it may also be other thread structures.

As shown in FIG7 , the water inlet joint and the water outlet joint each include two grooves, respectively located below the threaded portion and below the opening portion, for fixing the seal. In this embodiment, as shown in FIG8 , the seal is an O-ring, which is sleeved on the two grooves of the water inlet joint and the water outlet joint. When the screws are tightened, the two O-rings on the joint are in a compressed state to fill the gap between the water cooling plate joint and the water distributor.

FIG9 is a schematic diagram of the structure of the water distributor of the embodiment of the present invention. As shown in FIG9 , taking the water inlet connector end as an example, the water distributor is a hollow structure, one end of which is the water inlet end, and a plurality of through holes are correspondingly opened on two opposite side surfaces, which are connected with the hollow structure; the water inlet connector and the water outlet connector pass through the plurality of through holes to achieve connection with the water distributor. In the embodiment shown in FIG9 , the water distributor has 6 through holes, so it can be directly connected to the water outlet connectors of 6 water cooling modules. If a water cooling module includes 3 water cooling plates, it means that the water distributor can provide water inlet to 18 water cooling plates at the same time.

By using the hard connection method of the embodiments shown in Figures 6 to 9, the hard connection of the water distributor and the water cooling module joint is directly achieved with metal parts, and there is no need to use a hose connection, so the assembly is simple and the reliability is high; in addition, the water inlet joint and the water outlet joint of the water cooling module adopt an innovative design, with water entering from the side and M3 threads tapped on the top. The threaded part is completely isolated from the water channel, which is beneficial to prevent water leakage; a groove is designed at the position of the fixed O-ring on the joint to prevent the sealing ring from falling off; and the O-ring is used to compress the gap between the water cooling plate joint and the water distributor, which is efficient and easy to assemble.

The embodiment of the present invention further discloses a computing device, which includes at least one computing board and a water-cooling radiator, wherein the water-cooling radiator is attached to the at least one computing board to achieve heat dissipation of the at least one computing board. The water-cooling radiator is the water-cooling radiator described in any of the aforementioned embodiments of the present invention.

The water-cooled radiator and at least one computing board are bonded together by a heat-conducting material. In one embodiment, each computing board can be bonded between two water-cooled boards to achieve an optimal heat dissipation effect.

In the embodiment of the present invention, the computing device may be a server device having multiple PCB boards.

The water-cooled radiator and computing device disclosed in the embodiments of the present invention stack multiple water-cooling plates into a water-cooling module. The water-cooling plates in the same water-cooling module are connected by sealed joints. Each water-cooling module has only one water inlet joint and one water outlet joint, so some flexible hoses and water distributors can be omitted, the number of screw components is reduced, the solution cost is reduced, and the installation complexity is simplified. In addition, since the water-cooling plates in the embodiments of the present invention are connected end to end, the accuracy requirements for the structural dimensions are not high, as long as the interface dimensions between the two water-cooling plates are accurately matched, the high-precision matching dimension requirements when using one water distributor for multiple water-cooling plates are avoided. In addition, in the embodiments of the present invention, the existing screws for fixing the water-cooling plates also play a role of sealing and fastening, which can also reduce the solution cost and simplify the installation complexity.

The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
