Description

Technical Field

[0001] The invention relates to the technical field of radiator structures, in particular to a hinged folding liquid cooling plate. Background Art

[0002] Liquid cooling plates are widely used in electronic devices such as high-performance computers, servers, and communication equipment. These electronic devices generate a lot of heat during operation. If the heat cannot be dissipated at high temperatures, the performance and life of the equipment will be affected. Liquid cooling plates can effectively reduce the temperature of the equipment. As an efficient heat dissipation technology, liquid cooling plates have broad market prospects. With the continuous progress and development of electronic equipment, the demand for heat dissipation technology is also increasing. Existing electronic equipment generally performs liquid cooling on one side, but for large heat generation, when single-sided liquid cooling cannot provide stable and reliable cooling, it is generally necessary to set up two or even multiple liquid cooling plates for cooling. Existing liquid cooling plates are all single-sided structures, and an independent liquid cooling plate needs to be set corresponding to the surface of each heat source. Each liquid cooling plate needs to be set up with an independent liquid inlet, liquid outlet, and corresponding inlet and outlet pipelines, which leads to a complex pipeline structure of the liquid cooling plate for electronic equipment that needs to dissipate heat on multiple sides. Summary of the invention

DETAILED DESCRIPTION

[0028] Hinged folding liquid cold plate, see Figure 1-Figure 5 , which includes a first water-cooling plate 10, a second water-cooling plate 20, at least one flexible tube 30, a hinge connection structure 40, and two water nozzles;

[0029] The first water cooling plate 10 includes a first bottom plate 11, a first cover plate 12, and a first heat dissipation PIN assembly 13. The first bottom plate 11 is covered with the first cover plate 12 to form a first liquid cooling cavity. The first heat dissipation PIN assembly 13 is fixedly arranged in the first liquid cooling cavity. The first cover plate 12 is provided with a first liquid inlet and outlet 14 at one end away from the hinge connection structure 40. The first liquid inlet and outlet 14 is fixedly arranged with a first water nozzle 50.

[0030] The second water cooling plate 20 includes a second bottom plate 21, a second cover plate 22, and a second heat dissipation PIN assembly 23. The second bottom plate 21 is covered with the second cover plate 22 to form a second liquid cooling cavity. The second heat dissipation PIN assembly 23 is fixedly arranged in the second liquid cooling cavity. The second cover plate 22 is provided with a second liquid inlet and outlet 24 at one end away from the hinge connection structure 40. The second liquid inlet and outlet 24 is fixedly arranged with a second water nozzle 60.

[0031] The first water-cooled plate 10 and the second water-cooled plate 20 are connected by a hinge connection structure 40, and the first water-cooled plate 10 and the second water-cooled plate 20 are relatively rotated at 0° to 360° (in specific implementation, due to the height of the first water nozzle 50 and the second water nozzle 60, 360° cannot be reached, and the maximum is generally 330° according to actual conditions). In the horizontal arrangement state, a flexible tube 30 is provided between the facing end surfaces of the first water-cooled plate 10 and the second water-cooled plate 20, and the two ends of the flexible tube 30 are respectively connected to the corresponding liquid cooling cavities of the first water-cooled plate 10 and the second water-cooled plate 20.

[0032] In a specific implementation, the facing end surfaces of the first bottom plate 11 and the second bottom plate 21 in a horizontal arrangement state are respectively provided with side convex row tooth blocks, the side convex row tooth block corresponding to the first bottom plate 11 is the first side convex row tooth block 15, and the side convex row tooth block corresponding to the second bottom plate 21 is the second side convex row tooth block 25, the first side convex row tooth block 15 and the second side convex row tooth block 25 are arranged with an offset insertion arrangement along the length direction, the first side convex row tooth block 15 and the second side convex row tooth block 25 are respectively provided with a through shaft hole 1, the rotating shaft is inserted into the first side convex row tooth block 15 and the second side convex row tooth block 25 to form a through shaft hole 1 to form a hinge connection structure 40.

[0033] In specific implementation, the entire liquid cooling plate includes two flexible tubes 30, and both ends of the hinge connection structure 40 in the length direction are retracted to the length of the facing end surfaces of the first bottom plate 11 and the second bottom plate 21. The facing end surfaces of the first bottom plate 11 and the second bottom plate 21 are respectively provided with corresponding connecting holes 2 corresponding to the outer end areas on both sides of the hinge connection structure 40. Each flexible tube 30 is respectively sealed and connected to the connecting holes 2 on both sides corresponding to the corresponding positions in the length direction, so that the liquid cooling cavities of the two groups of water cooling plates are connected through the two groups of bypass tubes 30.

[0034] In a specific implementation, the first water nozzle 50 is located at the center of the length direction area of ​​the corresponding side area of ​​the first cover plate 12, and the second water nozzle 60 is located at the center of the length direction area of ​​the corresponding side area of ​​the second cover plate 22;

[0035] The first water nozzle 50 and the second water nozzle 60 are staggered when the hinge connection mechanism 40 rotates to the maximum angle, which makes the two groups of water nozzles not overlap each other, ensuring that the entire liquid cooling plate can adapt to position adjustment at a sufficiently large angle.

[0036] In a specific implementation, the shaft includes a shaft body 41 and locking heads 42 at both ends. The shaft body 41 passes through the corresponding through-shaft holes 1 of the first side convex row of gear blocks 15 and the second side convex row of gear blocks 25, and the two ends of the shaft body 41 are locked by the locking heads 42, so that the assembly of the shaft is stable and reliable.

[0037] A sealant is applied to the connection position between the flexible tube 30 and the connecting hole 2 to prevent leakage of liquid.

[0038] In specific implementation, during the rotation of the first liquid cooling plate and the second liquid cooling plate, deformation space for the flexible tube 30 is reserved on the outer sides of both ends of the hinge connection mechanism 40 in the length direction, so as to ensure reliable and stable operation of the entire mechanism.

[0039] In a specific implementation, the first water nozzle 50 of the first liquid cooling plate 10 allows the cooling medium to flow in, and the second water nozzle 60 of the second liquid cooling plate 20 allows the cooling medium to flow out.

[0040] The first liquid cooling plate 10 and the second liquid cooling plate 20 are both independently manufactured. Each group of the bottom plate, the cover plate, the water nozzle, and the heat dissipation PIN assembly are brazed to form a corresponding liquid cooling plate. After that, the side convex tooth blocks of the two bottom plates are mutually offset and inserted and arranged along the length direction to form a connected integrated through-axis hole. The shaft body 41 penetrates the through-axis hole 1 and is provided with a large-diameter locking head 42 at both ends. The two groups of water cooling plates after assembly are connected by a flexible tube 30 and fixed with a sealant to prevent water leakage. The cooling medium enters through the first water nozzle 50, flows through the first heat dissipation PIN group 13 in the first water cooling plate 10, passes through two groups of flexible tubes 30 at upper and lower positions, and then flows into the second liquid cooling cavity of the second water cooling plate 20, and then flows through the second heat dissipation PIN assembly 23. The medium flows out from the second water nozzle 60. Such repeated operation takes away a large amount of heat, meeting the advantage of high-performance heat dissipation of the water cooling plate.

[0041] The principle is as follows: according to the angles of adjacent heat dissipation surfaces, as well as the areas and shapes of the heat dissipation surfaces, a first liquid cooling plate and a second liquid cooling plate of corresponding areas and shapes are manufactured, and a hinge connection structure enables the first liquid cooling plate and the second liquid cooling plate to be opened and closed to corresponding angles, so that the surfaces of the two liquid cooling plates without water nozzles are attached to the corresponding heat dissipation surfaces, and the cooling medium flows in from one of the liquid inlets and outlets, flows through the two liquid cooling chambers in sequence through the flexible tube for heat exchange, and finally flows out from the other liquid inlet and outlet. It only needs to set up a set of water nozzle joints and external pipelines. For electronic equipment with two heat dissipation surfaces arranged at a certain angle, it can save space for pipeline layout, so that the internal space of the corresponding electronic equipment can be arranged more reasonably and reliably.
