Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling plates, in particular to a supporting plate structure of a server liquid cooling plate. Background Art

[0002] A liquid cooling plate is a heat exchanger or radiator, a key component of a data center's liquid cooling system. Installed on the hot surfaces of electronic components requiring cooling, it transfers the generated heat to the plate heat exchanger in the cooling distribution unit via a liquid coolant. Typically, a liquid cooling plate requires a support plate to ensure a close fit with the surface of the heat generating unit to ensure effective heat dissipation. Existing liquid cooling plate support plates are monolithic structures, which place high demands on the processing equipment, such as high die-casting and forging tonnage. The associated molds and jigs are also bulky, resulting in high manufacturing costs. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a support plate structure for a server liquid cooling plate, which is a split structure and is suitable for smaller tonnage casting and forging equipment, and reduces the volume of related molds and fixtures, thereby reducing production costs.

[0004] The technical solution of the utility model is:

[0011] The bottom surface of the middle end of the side of the second support plate away from the first support plate is indented toward the surface thereof to form a second groove surface.

[0012] Furthermore, a plurality of mounting holes are provided on the first groove surface, and a plurality of mounting holes are provided on the second groove surface.

[0013] Furthermore, the upper surfaces of the two ends of the side of the first support plate away from the second support plate are respectively sunken, and the bottom surfaces at the corresponding positions are respectively retracted toward the upper surface, each forming an elastic component mounting portion;

[0014] The upper surfaces of the second support plate at both ends of the side away from the first support plate are respectively sunken, and the bottom surfaces at the corresponding locations are respectively retracted toward the upper surface, each forming an elastic component mounting portion;

[0022] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] like Figure 1-Figure 3 As shown, the present invention provides a support plate structure for a server liquid cooling plate, which is used to provide pressure support for the liquid cooling plate, allowing it to fit tightly against the heat generating unit while preventing it from deforming under pressure. The liquid cooling plate described in the present invention is primarily used in servers. The liquid cooling plate of the present invention includes two opposing side edges and a liquid cooling plate body located on both sides. The height of the liquid cooling plate body is higher than the height of the side edges.

[0024] The present invention provides a support plate structure for a server liquid cooling plate, comprising a first support plate 100 and a second support plate 200. The first support plate 100 and the second support plate 200 are C-shaped plates that are mirror-symmetrical.

[0025] The bottom surfaces of the ends of the two opposite opening edges of the first support plate 100 are each retracted toward the surface thereof, forming two first mounting portions 101 with concave surfaces. Two docking holes 400 are symmetrically spaced apart on each first mounting portion 101 .

[0026] The surfaces of the ends of the two opposite open edges of the second support plate 200 are each sunken toward the bottom thereof to form two second mounting portions 201 with sunken surfaces. Two docking holes 400 are symmetrically spaced apart on each second mounting portion 201 .

[0027] Each first mounting portion 101 is placed above its corresponding second mounting portion 201. The docking holes 400 on the first and second mounting portions 101 and 201 correspond one to one. A fastener 300 is secured within each pair of docking holes 400. This connects the first and second support plates 100 and 200 to form a single, integrated plate, with their top surfaces aligned horizontally. The liquid cooling plate is placed within the cavity enclosed by the first and second support plates 100 and 200. The fasteners 300 in this embodiment are screws.

[0028] Compared with the design of the support plate as a whole plate in the existing technology, the split support plate design has lower requirements on equipment processing capabilities. It is suitable for smaller tonnage casting and forging equipment, and reduces the volume of related molds and fixtures, thereby reducing production costs.

[0029] Furthermore, to secure the liquid cooling plate within the cavity enclosed by the first support plate 100 and the second support plate 200, the bottom surface of the intermediate end of the side of the first support plate 100, distal from the second support plate 200, is recessed toward the surface to form a first recessed surface 102. Two mounting holes 401 are symmetrically spaced apart on the first recessed surface 102. The bottom surface of the intermediate end of the side of the second support plate 200, distal from the first support plate 100, is recessed toward the surface to form a second recessed surface 202. Two mounting holes 401 are symmetrically spaced apart on the second recessed surface 202. The opposing sides of the liquid cooling plate are positioned within the first and second recessed surfaces 102, 202, respectively. The liquid cooling plate body, located between its two sides, is positioned within the cavity enclosed by the first and second support plates 100, 200. In actual use, a fastener 300 is secured within each mounting hole 401 to secure the first and second support plates 100, 200, to the respective sides of the liquid cooling plate.

[0030] Furthermore, to ensure a close fit between the liquid cooling plate and the heat generating unit and ensure effective heat dissipation, the upper surfaces of the first support plate 100 at both ends of the side facing away from the second support plate 200 are lowered, and the corresponding bottom surfaces are retracted inward toward the upper surface, forming two elastic component mounting portions 500. Each elastic component mounting portion 500 is provided with a through-hole 501. Similarly, two elastic component mounting portions 500 are also provided at both ends of the side facing away from the first support plate 200, each of which is equipped with a screw elastic component.

[0031] The screw elastic assembly includes an O-ring, a screw 600, and a spring 601. In actual use, an O-ring (not shown) is placed between the bottom surface of each elastic assembly mounting portion 500 and the surface of the heating unit. A spring 601 is sleeved around the outer circumference of each screw 600. The lower end of each screw 600 passes through a through-hole 501 and an O-ring in sequence, and its bottom end is fixed to the surface of the heating unit. One end of the spring 601 abuts against the upper surface of the elastic assembly mounting portion 500, and the other end abuts against the lower surface of the screw head of the screw 600. At this point, the first support plate 100 and the second support plate 200 are respectively fixed to the heating unit. The deformation stroke of the spring 601 can be selected according to the specific size of the heating unit and the liquid cooling plate to achieve the tightness of the connection between the first support plate 100 and the second support plate 200 and the heating unit, thereby controlling the tightness of the fit between the liquid cooling plate and the heating unit, avoiding the two from being too tight and damaging the liquid cooling plate, or avoiding the two from being loose and reducing the heat dissipation efficiency of the heating unit.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
