Description

Water cooling head buckle structure

The invention relates to a water-cooling head buckle structure, in particular to a water-cooling head buckle structure that reduces cost and improves production efficiency.

With the advancement of technology, the operating frequency of electronic products (such as computers, servers or communication boxes) is getting faster and faster, so that the heat generated during operation has also increased, and the relative heat dissipation requirements have also increased. Among them, the server In other words, due to the server’s processing of big data and cloud computing, the existing air-cooling can no longer afford the heat dissipation requirements of current electronic products such as central processing units (CPU), graphics card chips (GPU), north-south bridge chips or ASIC chips. Therefore, the industry has developed a water-cooled plate to meet the heat dissipation requirements of the above numbers.

The existing general cold plate (Cold Plate) structure design is usually composed of a bottom plate made of copper material and an upper cover plate made of copper material, and the upper cover plate is covered on the bottom plate, and the upper cover plate There are a plurality of corresponding keyholes on one side of the bottom plate, and the keyholes of the upper cover plate and the keyholes of the lower cover are sequentially inserted through the plurality of screws to the corresponding keyholes on the motherboard The inner screw lock is fixed, so that the water-cooling plate is locked on a heating element (such as a central processing unit (CPU), a graphics card chip (GPU) or an ASIC chip) of the motherboard to perform water cooling and heat dissipation of the heating element.

The positions of the locking holes of the upper cover plate itself and the locking holes of the lower cover plate of the existing water-cooling plate are designed according to the specifications and models of the heating elements of the motherboard and the requirements of the manufacturer. Because not Heating elements of the same specifications (such as central processing unit, graphics card chip (GPU), north-south bridge chip or ASIC chip) need water-cooled plates with different locking hole positions, such as the same brand of different specifications and models of central processing units (such as INTEL I3-CPU or INTEL I7-CPU), it is necessary to design a corresponding water-cooling plate with different locking hole positions (for example, the water-cooling plate corresponding to INTEL I3-CPU is designed with 4 locking holes opened in the four corners of the water-cooling plate or corresponding to INTEL I5-CPU's water-cooling board design 6 locking holes are provided on the upper and lower periphery of the water-cooling board), or a central processor of a different brand (such as INTEL I7-CPU or AMD Ryzen 7-CPU) also needs to be designed accordingly Another type of water-cooling plate with different locking hole positions (for example, the water-cooling plate design corresponding to INTEL I7-CPU has 5 locking holes at the corners of the water-cooling plate or the water-cooling plate corresponding to AMD Ryzen 7-CPU has 8 locking holes. The holes are opened on the left and right periphery of the water-cooling plate), which leads to poor versatility of the water-cooling plate. The production plant needs to design the corresponding motherboard and heating element molds for each type of water-cooling plate, resulting in the need for separate production, design and development. High cost and high production cost, and many problems such as the inability to achieve mass production, the inability to unify, and the high risk of management and control.

In addition, both the upper cover and the bottom plate of the existing water-cooled plate are separately manufactured by computer numerical control (CNC) processing, and the upper cover and the bottom plate are connected together by brazing. However, because the upper cover and Both the bottom plate are made of the same copper material, and there must be additional locking holes for locking with the motherboard, so that the upper cover and the bottom plate need to be extended outward in manufacturing. The location to open the locking hole causes the water-cooling plate to be large and heavy, and the cost is relatively increased.

One purpose of the present invention is to provide a water-cooling head buckle structure that can save costs.

Another object of the present invention is to provide a structural design of a water block with a modularized water block that can achieve mass production, increase process stability, reduce research and development costs, reduce control risks, and reduce weight.

Another object of the present invention is to provide a water block formed by welding an upper part formed by metal forging processing (such as hot forging processing) and a lower part formed by metal cutting processing (such as CNC processing) by welding. The structural design of the upper part can effectively eliminate the use of CNC processing to form the upper part, thereby achieving a water block buckle structure that saves the upper part in the manufacturing process.

To achieve the above objective, the present invention is to provide a water-cooling head buckle structure, which is applied to a water-cooling head and attached to a main board with a heating element to connect with the water-cooling head. It includes a buckle, the buckle has a hollow opening and a plurality of through holes, the opening and the through holes respectively penetrate the buckle, and the through holes are arranged along the peripheral side of the buckle for A plurality of fixing members on the main board are provided for penetration and fixing, and the opening of the buckle is sleeved on the water cooling head, so that the water cooling head is connected to the buckle; through the structure design of the water cooling head buckle of the present invention, According to the brand and specifications of the heating element on the motherboard, the through hole position is designed and adjusted to meet the heating element, and it also effectively saves R&D costs, reduces production costs, and reduces the overall weight of the water block buckle structure.
