Description

Combined water-cooling module fastener structure

Technical Field

The present invention relates to a fastener structure of a combined water-cooling module, and more particularly, to a fastener structure of a combined water-cooling module, which is convenient and free to assemble, and has high freedom and structural strength.

Background

With the demand for big data and cloud computing services being greatly increased, the heat dissipation demand of related electronic products (such as computers, servers, large computing centers or communication cabinets) is also increasing, especially for servers of large computing centers, the computing density is increased, the waste heat generated in the space with the same size is also greatly increased, and in order to reduce the energy consumed by heat dissipation, the design of the heat sink is gradually changed from the traditional air cooling using fans to the use of liquid to take away the heat source from the server and dissipate the heat in other ways, so as to solve the problem of high-density waste heat generation.

In past electronic products using air cooling, each wafer corresponds to a single radiator (Heat Sink), and if a plurality of wafers are arranged in the system, the wafers also correspond to a plurality of groups of air cooling radiators; when the heat dissipation device is converted into a liquid-cooled heat dissipation product, a water pipeline, a pump and the like need to be configured in a limited casing space, however, in a narrow space, the main factors influencing the pipeline configuration include: the main board configuration, the water cooling head inlet and outlet directions, the inner and outer diameters of pipelines (namely a water inlet pipeline and a water outlet pipeline), the minimum bending radius of the pipelines and the like.

In the process of changing from air cooling to liquid cooling, the client motherboard is often configured with the thinking of air cooling and cannot be designed and changed, so that downstream manufacturers are limited everywhere when configuring pipelines of the water cooling module, and a great deal of design change of water cooling products is brought about.

Referring to fig. 4A and 4B, when the water cooling head 3 is made of a copper material with better heat transfer effect and fixed near a heat source (a Central Processing Unit (CPU), a display card chip (GPU), a north-south bridge chip or an ASIC chip), because the material is soft and cannot be directly locked on the heat source, the water cooling head needs to be sleeved with an integrated fastener 4 from the right top to the bottom of the water cooling head 3, so that two openings 41 formed in the fastener 4 correspond to an L-shaped water inlet nozzle 31 and a water outlet nozzle 32 formed in the water cooling head 3, and then the fastener 4 and the water cooling head 3 are combined and then locked by a locking structure of the fastener 4 and the periphery of the heat source. The water inlet nozzle 31 and the water outlet nozzle 32 provided on the water cooling head 3 are fixed on the water cooling head 3 by welding in order to prevent leakage.

Therefore, when the arrangement direction of the two openings 41 of the buckle 4 is different from the arrangement direction of the water inlet nozzle 31 and the water outlet nozzle 32 on the water cooling head 3, the buckle 4 is interfered by the arrangement direction of the water inlet nozzle 31 or the water outlet nozzle 32 and cannot be sleeved and combined, and the water inlet nozzle 31 and the water outlet nozzle 32 are fixed on the water cooling head 3 by welding and cannot be rotated and changed in direction, so that a manufacturer must additionally set a mold to manufacture the buckle 4 component having the same arrangement direction as the water inlet nozzle 31 or the water outlet nozzle 32 of the water cooling head 3, and the water cooling head 3 of each specification/brand must additionally set different molds, and the manufacturing cost is considerably increased. In addition, the openings 41 with different angles formed on the buckle 4 affect the overall structural strength of the buckle 4, and it is necessary to perform a long-time structural strength test and adjustment on each buckle 4 with openings 41 with different angles or redesign the overall structure of the buckle 4, which results in a problem of cost increase and labor consumption.

Therefore, how to improve the problem of interference between the buckle 4 and the water cooling head 3, and the like, and the inconvenience and trouble of assembly and the low degree of freedom of assembly are the key points to be solved.

The prior water cooling head 3 and the buckle 4 have the following disadvantages:

1. the directions of the water inlet nozzle head 31 and the water outlet nozzle head 32 of the water cooling head 3 are limited by the installation mode of the water cooling head 3.

2. The water head 3 may have insufficient structural strength in the face of wafer design trends. In the assembly process, the water pipeline can be installed only after the adapter buckle 4 is installed.

3. In the aspect of disassembly, assembly or maintenance, the single-piece (integrated) buckle 4 is interfered by the water inlet nozzle 31 and the water outlet nozzle 32, so that the problems of quick disassembly, quick assembly and quick maintenance cannot be achieved in use, and the problem of poor convenience in use is caused.

In another embodiment, the first and second fastener members 11, 12 and the water-cooling module 2 may be provided with a through hole (not shown) at the corresponding position at the bottom four corners, and the water-cooling module 2 and the plurality of fastener members (such as the first and second fastener members 11, 12) may be fastened and fixed by a plurality of screws to enhance the bonding strength between the water-cooling module 2 and the plurality of fastener members.

Therefore, the combined design of the plurality of buckle components and the water-cooling module 2 can achieve convenient assembly and high assembly freedom, and because the plurality of buckle components can also be modularized, if one buckle component (such as the first buckle component 11) is damaged, the damaged buckle component can be combined and connected with another buckle component (such as the second buckle component 12) which is not damaged originally for use again only by replacing the damaged buckle component with a new buckle component (such as the first buckle component 11) in the same direction, so as to effectively achieve the purpose of reducing the cost. In addition, the two nozzles (the water inlet nozzle 27 and the water outlet nozzle 28) welded and fixed on the top side of the water-cooling module 2 can be connected and combined with the water-cooling module 2 into a whole through the plurality of fastener members (such as the first fastener member 11 and the second fastener member 12) no matter the arrangement directions are the same or different, so that the problem that the cost is increased because different molds must be arranged on the bottom plate of the water-cooling head according to the water-cooling heads of the nozzles in different directions in the prior art can be solved.
