Description

Water cooling head buckle structure

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

With the advancement of technology, the operating frequency of electronic products (such as computers, servers or communication chassis) is getting faster and faster, so that the heat energy generated during operation is also increased, and the relative heat dissipation requirements are also increased. Generally speaking, 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 unit (CPU), graphics card chip (GPU), north-south bridge chip or ASIC chip Therefore, the industry has developed a water cooling plate to meet the above heat dissipation requirements. The structure design of the existing general cold plate 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 closed on the bottom plate and the upper cover plate There are a plurality of lock holes corresponding to one side of the bottom plate, and the lock holes of the upper cover plate and the lock holes of the lower cover are sequentially threaded through the plurality of screw pieces to the corresponding lock holes on a main board The internal screw lock is fixed, so that the water cooling plate is fixed on a heating element (such as a central processing unit (CPU), a graphics card chip (GPU) or an ASIC chip) of the main board, so as to perform water cooling on the heating element. The positions of the locking holes of the upper cover plate of the existing water cooling plate and the locking holes of the lower cover plate are designed according to the specifications of the heating element of the motherboard and the requirements of the brand, Because different specifications and types of heating elements (such as central processing unit, graphics card chip (GPU), north-south bridge chip or ASIC chip) require water-cooled plates with different locking hole positions, such as different specifications and types of central processors of the same brand ( For example, INTEL I3-CPU or INTEL I7-CPU, you need to design a water cooling plate with a different locking hole position (for example, the water cooling plate corresponding to INTEL I3-CPU is designed with 4 locking holes opened at the four corners of the water cooling plate or corresponding The water cooling plate of INTEL I5-CPU is designed with 6 locking holes opened at the upper and lower periphery of the water cooling plate), or central processors of different brands (such as INTEL I7-CPU or AMD Ryzen 7-CPU) also need to correspond Design another water-cooled plate with different locking holes (such as the water-cooled plate corresponding to the INTEL I7-CPU design 5 locking holes opened at the corners of the water-cooled plate or the water-cooled plate corresponding to the AMD Ryzen 7-CPU design 8 locks The fixing holes are opened on the left and right sides of the water cooling plate), which leads to poor generality of the water cooling plate, so the production plant needs to design the mold corresponding to the motherboard and the heating element for each water cooling plate, resulting in the need for separate production and design R&D costs are high and production costs are high, and many problems such as mass production, unification and high control risks have not yet been achieved. In addition, both the upper cover plate and the bottom plate of the existing water-cooled plate are separately manufactured by computer numerical control equipment (CNC) processing, and the upper cover plate and the bottom plate are connected together by brazing, but the upper cover plate and the bottom plate are connected together. Both of the bottom plates are made of the same copper material, and the positions of the locking holes that are locked with the main board must be reserved on both of them, so that the upper cover plate and the bottom plate need to be extended outwards in manufacturing. The locking hole is opened at the location, which leads to the overall large and heavy weight of the water cooling plate, and the cost is also relatively increased.
