Description

Technical Field

[0001] The present application relates to the technical field of hard disk installation, and in particular to a floating disk box and a server. Background Art

[0002] With the improvement of server system integration, the power consumption of server equipment is getting higher and higher, and the density of hard disks is also getting higher and higher. At present, air cooling can no longer meet the heat dissipation requirements of high-density hard disks. Liquid cooling, as an effective heat dissipation method, is widely used in server equipment to achieve heat dissipation. In the related technology, the server includes a chassis, a liquid-cooled cold plate and a disk box. The cold plate is installed in the chassis, and the heat dissipation cold plate of the disk box is in contact with the liquid-cooled cold plate to achieve heat dissipation of the disk box. However, the existing heat dissipation cold plate and liquid-cooled cold plate of the disk box mainly solve the contact problem by compressing the thermal pad. When the manufacturing error is large, if the thermal pad is not fully compressed, it will affect the thermal conductivity between the heat dissipation cold plate and the liquid-cooled cold plate, thereby affecting the heat dissipation of the hard disk. Utility Model Content

[0003] Based on this, it is necessary to provide a floating disk box and server to solve the contact problem between the disk box and the liquid-cooled cold plate.

[0004] A floating disk box, the floating disk box comprising:

[0005] A hard disk and a heat dissipation cold plate connected to each other, wherein the heat dissipation cold plate comprises a first end and a second end distributed along a first direction, wherein the first direction is a length direction of the heat dissipation cold plate;

[0006] A disk rack having a receiving cavity, wherein the hard disk and the heat dissipation cold plate are both arranged in the receiving cavity;

[0007] An elastic member is connected between the cavity wall of the accommodating cavity and the second end, so that the first end elastically abuts against the liquid-cooled cold plate.

[0008] The above-mentioned floating disk box connects the hard disk and the heat dissipation cold plate. The first end of the heat dissipation cold plate can contact the liquid cooling cold plate, so that the heat of the hard disk is transferred to the liquid cooling cold plate through the heat dissipation cold plate, thereby realizing the cooling of the hard disk. An elastic member is connected to the cavity wall of the accommodating cavity, and the connected hard disk and the heat dissipation cold plate are both installed in the accommodating cavity of the disk rack. The elastic member is located between the cavity wall and the second end of the accommodating cavity, and abuts against the second end of the heat dissipation cold plate. The elastic member pushes the heat dissipation cold plate to move in the direction close to the liquid cooling cold plate through its own elastic force, so that the first end elastically abuts against the liquid cooling cold plate, thereby realizing the close contact between the heat dissipation cold plate and the liquid cooling cold plate, improving the heat conduction efficiency between the heat dissipation cold plate and the liquid cooling cold plate, and improving the heat dissipation of the hard disk.

[0009] In one embodiment, the elastic member includes an elastic module, which includes a first force arm, a ring body and a second force arm. The ring body is rotatably matched with the disk rack. One end of the first force arm is connected to the ring body, and the other end is connected to the cavity wall of the accommodating cavity. One end of the second force arm is connected to the ring body, and the other end abuts against the heat dissipation cold plate.

[0010] The first force arm of the elastic module is connected to the cavity wall of the accommodating cavity, and the ring body is rotatably connected to the disk rack. The second force arm of the elastic module can abut against the second end of the heat dissipation cold plate. The second force arm abuts against the second end of the heat dissipation cold plate, thereby pushing the heat dissipation cold plate to move toward the liquid-cooled cold plate to achieve close contact between the heat dissipation cold plate and the liquid-cooled cold plate.

[0011] In one embodiment, the elastic member further includes a connecting arm, the elastic member includes two elastic modules, and the two second force arms of the two elastic modules are connected via the connecting arm.

[0012] Two elastic modules are provided, and the two second force arms of the two elastic modules are connected by a connecting arm. The two second force arms and the connecting arm can abut against the second end of the heat dissipation cold plate, thereby increasing the contact area between the elastic member and the heat dissipation cold plate and improving the pushing effect.

[0013] In one of the embodiments, two fixing posts are arranged on the cavity wall of the accommodating cavity, and the two ring bodies of the two elastic modules are sleeved on the two fixing posts in a one-to-one correspondence.

[0014] By arranging a fixing column on the cavity wall of the accommodating cavity, the ring body of the elastic module can be sleeved on the fixing column and rotatably cooperate with the fixing column, so as to realize the rotatable cooperation between the elastic module and the disk rack, thereby making the heat dissipation cold plate have the function of floating forward and backward.

[0015] In one embodiment, two elastic members are provided, and the two elastic members are arranged at intervals along a second direction, and the second direction is a width direction of the heat dissipation cold plate.

[0016] Two elastic members are provided and arranged at intervals along the second direction. The two elastic members can act at the same time and both push the heat dissipation cold plate to move in a direction close to the liquid cooling cold plate, thereby improving the pushing effect.

[0017] In one of the embodiments, it also includes a fixed base, which has an installation space, the heat dissipation cold plate and the hard disk are both arranged in the installation space, the fixed base is arranged in the accommodating cavity and connected to the cavity wall of the accommodating cavity, and the elastic member abuts against the fixed base.

[0018] By setting a fixed base, the heat dissipation cold plate and the hard disk are both set in the installation space of the fixed base, and then the fixed base is set in the accommodating cavity and connected to the cavity wall of the accommodating cavity, so as to realize the connection between the heat dissipation cold plate, the hard disk and the disk rack. When the fixed base is set in the accommodating cavity, the elastic member abuts against the heat dissipation cold plate through the fixed base, and the elastic member pushes the fixed base to float, thereby pushing the heat dissipation cold plate and the hard disk to float.

[0019] In one embodiment, the fixed base and the cavity wall of the accommodating cavity are slidably matched.

[0020] The fixed base and the cavity wall of the accommodating cavity are slidably matched, that is, the fixed base can slide relative to the disk rack, that is, the heat dissipation cold plate can slide relative to the disk rack, thereby limiting the floating direction of the fixed base and the heat dissipation cold plate.

[0021] In one of the embodiments, a buckle is provided on the fixed base, and a slide extending along the first direction is provided on the disk rack, and the buckle can extend into the slide and slide relative to the slide.

[0022] By setting a buckle on the fixed base and a slide on the disk rack, when the fixed base is set in the accommodating cavity of the disk rack, the buckle extends into the slide, thereby realizing the relative position limitation of the fixed base and the disk rack. The elastic member abuts against the fixed base, and the elastic member can push the fixed base to slide in the direction away from the disk rack, that is, to slide in the direction close to the liquid-cooled cold plate. At this time, the buckle slides in the slide, and because the slide extends in the first direction, the sliding direction of the fixed base is limited, so that it can only slide in the first direction. The present application uses the elastic member to push the heat dissipation cold plate and the liquid-cooled cold plate into close contact, and by setting the buckle and the slide, the sliding direction of the fixed base and the heat dissipation cold plate is limited.

[0023] In one embodiment, it further includes a cold plate heat conduction block installed at the first end of the heat dissipation cold plate, and the heat dissipation cold plate is in contact with the liquid-cooled cold plate through the cold plate heat conduction block.

[0024] By arranging a cold plate heat conduction block at the first end of the heat dissipation cold plate, the heat dissipation cold plate abuts against the liquid cooling cold plate through the cold plate heat conduction block, thereby improving the heat conduction efficiency.

[0025] The present application also provides a server, comprising a chassis, a liquid-cooled cold plate, and any of the above floating disk boxes, wherein the liquid-cooled cold plate and the floating disk box are both connected to the chassis, and the first end of the heat dissipation cold plate abuts against the liquid-cooled cold plate.

[0026] In the server, both the liquid cooling plate and the floating disk box are installed on the chassis, and the heat dissipation plate of the floating disk box is in contact with the liquid cooling plate. The elastic member of the floating disk box pushes the heat dissipation plate to move closer to the liquid cooling plate through its own elastic force, thereby achieving close contact between the heat dissipation plate and the liquid cooling plate. The server of the present application solves various errors in the chassis and the processing process through the elastic function of the elastic member, so that the heat dissipation plate and the liquid cooling plate are always in full contact.

[0049] The present application provides a floating disk box, such as Figures 1 to 7 As shown, the floating disk box includes: a hard disk 100 and a heat dissipation cold plate 200, a disk rack 300 and an elastic member 400, the hard disk 100 and the heat dissipation cold plate 200 are connected, the heat dissipation cold plate 200 includes a first end and a second end distributed along a first direction, and the first direction is the length direction of the heat dissipation cold plate 200; the disk rack 300 has a accommodating cavity 310, and the hard disk 100 and the heat dissipation cold plate 200 are both arranged in the accommodating cavity 310; the elastic member 400 is connected to the cavity wall of the accommodating cavity 310, and between the second end, so that the first end elastically abuts against the liquid-cooled cold plate 700.

[0050] The above-mentioned floating disk box connects the hard disk 100 and the heat dissipation cold plate 200. The first end of the heat dissipation cold plate 200 can contact the liquid cooling cold plate 700, so that the heat of the hard disk 100 is transferred to the liquid cooling cold plate 700 through the heat dissipation cold plate 200, so as to achieve the cooling of the hard disk 100. The elastic member 400 is connected to the cavity wall of the accommodating cavity 310, and the connected hard disk 100 and the heat dissipation cold plate 200 are both installed in the accommodating cavity 310 of the disk rack 300. The elastic member 400 is between the cavity wall and the second end of the accommodating cavity 310, and abuts against the second end of the heat dissipation cold plate 200. The elastic member 400 pushes the heat dissipation cold plate 200 to move in the direction close to the liquid cooling cold plate 700 through its own elastic force, so that the first end elastically abuts against the liquid cooling cold plate 700, thereby achieving close contact between the heat dissipation cold plate 200 and the liquid cooling cold plate 700, improving the heat conduction efficiency between the heat dissipation cold plate 200 and the liquid cooling cold plate 700, and improving the heat dissipation of the hard disk 100.

[0051] Specifically, Figures 1 to 6 As shown, the disk rack 300 is a semi-enclosed structure, and the disk rack 300 is provided with an opening to connect the outside and the accommodating cavity 310. When the elastic member 400 pushes the heat dissipation cold plate 200 to move toward the direction close to the liquid cooling cold plate 700, the liquid cooling cold plate 700 at least partially passes through the opening to move away from the disk rack 300.

[0052] More specifically, if Figures 1 to 6 As shown, the opening provided on the disk rack 300 is located at a side of the first end of the heat dissipation cold plate 200 away from the second end.

[0053] In some embodiments, Figures 1 to 6 As shown, the elastic member 400 includes an elastic module 410, and the elastic module 410 includes a first force arm 411, a ring body 412 and a second force arm 413. The ring body 412 is rotatably matched with the disk rack 300. One end of the first force arm 411 is connected to the ring body 412, and the other end is connected to the cavity wall of the accommodating cavity 310. One end of the second force arm 413 is connected to the ring body 412, and the other end abuts against the heat dissipation cold plate 200. The first force arm 411 of the elastic module 410 is connected to the cavity wall of the accommodating cavity 310, and the ring body 412 is rotatably connected to the disk rack 300. The second force arm 413 of the elastic module 410 can abut against the second end of the heat dissipation cold plate 200. The second force arm 413 abuts against the second end of the heat dissipation cold plate 200, thereby pushing the heat dissipation cold plate 200 to move in a direction close to the liquid cooling cold plate 700, so as to achieve close contact between the heat dissipation cold plate 200 and the liquid cooling cold plate 700.

[0054] Specifically, Figures 1 to 6 As shown, the elastic member 400 further includes a connecting arm 420, and the elastic member 400 includes two elastic modules 410, and the two second force arms 413 of the two elastic modules 410 are connected through the connecting arm 420. Two elastic modules 410 are provided, and the two second force arms 413 of the two elastic modules 410 are connected through the connecting arm 420. Both the two second force arms 413 and the connecting arm 420 can abut against the second end of the heat dissipation cold plate 200, thereby increasing the contact area between the elastic member 400 and the heat dissipation cold plate 200 and improving the pushing effect.

[0055] More specifically, the elastic member 400 is a torsion spring.

[0056] Specifically, Figures 1 to 6As shown, two fixing posts 320 are arranged on the cavity wall of the accommodating cavity 310, and two ring bodies 412 of the two elastic modules 410 are sleeved on the two fixing posts 320 in a one-to-one correspondence. By arranging the fixing posts 320 on the cavity wall of the accommodating cavity 310, the ring bodies 412 of the elastic modules 410 can be sleeved on the fixing posts 320 and rotatably cooperate with the fixing posts 320, so that the elastic modules 410 and the disk rack 300 can be rotated and cooperated, so that the heat dissipation cold plate 200 has the function of floating forward and backward.

[0057] Specifically, Figures 1 to 6 As shown, two elastic members 400 are provided, and the two elastic members 400 are arranged at intervals along the second direction, and the second direction is the width direction of the heat dissipation cold plate 200. Two elastic members 400 are provided, and the two elastic members 400 are arranged at intervals along the second direction. The two elastic members 400 can act at the same time, and both push the heat dissipation cold plate 200 to move in the direction close to the liquid cooling cold plate 700, thereby improving the pushing effect.

[0058] In some embodiments, Figures 1 to 6 As shown, the floating disk box also includes a fixed base 500, the fixed base 500 has an installation space 510, the heat dissipation cold plate 200 and the hard disk 100 are both arranged in the installation space 510, the fixed base 500 is arranged in the accommodating cavity 310, and is connected to the cavity wall of the accommodating cavity 310, and the elastic member 400 abuts against the fixed base 500. By setting the fixed base 500, the heat dissipation cold plate 200 and the hard disk 100 are both arranged in the installation space 510 of the fixed base 500, and then the fixed base 500 is arranged in the accommodating cavity 310 and is connected to the cavity wall of the accommodating cavity 310, thereby realizing the connection between the heat dissipation cold plate 200, the hard disk 100 and the disk rack 300. When the fixed base 500 is arranged in the accommodating cavity 310, the elastic member 400 abuts against the heat dissipation cold plate 200 through the fixed base 500, and the elastic member 400 pushes the fixed base 500 to float, which also pushes the heat dissipation cold plate 200 and the hard disk 100 to float.

[0059] Specifically, Figures 1 to 6 As shown, the fixed base 500 and the cavity wall of the accommodating cavity 310 are slidably matched. The fixed base 500 and the cavity wall of the accommodating cavity 310 are slidably matched, that is, the fixed base 500 can slide relative to the disk rack 300, that is, the heat dissipation cold plate 200 can slide relative to the disk rack 300, thereby limiting the floating direction of the fixed base 500 and the heat dissipation cold plate 200.

[0060] More specifically, if Figures 1 to 6As shown, a buckle 520 is provided on the fixed base 500, and a slideway 330 extending along the first direction is provided on the disk rack 300. The buckle 520 can extend into the slideway 330 and slide relative to the slideway 330. By providing the buckle 520 on the fixed base 500 and the slideway 330 on the disk rack 300, when the fixed base 500 is provided in the accommodating cavity 310 of the disk rack 300, the buckle 520 extends into the slideway 330, thereby realizing the relative position limitation of the fixed base 500 and the disk rack 300. The elastic member 400 abuts against the fixed base 500, and the elastic member 400 can push the fixed base 500 to slide in a direction away from the disk rack 300, that is, to slide in a direction close to the liquid-cooled cold plate 700. At this time, the buckle 520 slides in the slideway 330, because the slideway 330 extends along the first direction, thereby limiting the sliding direction of the fixed base 500, so that it can only slide along the first direction. The present application uses the elastic member 400 to push the heat dissipation cold plate 200 and the liquid cooling cold plate 700 into close contact, and defines the sliding direction of the fixed base 500 and the heat dissipation cold plate 200 by providing the buckle 520 and the slideway 330 .

[0061] More specifically, if Figures 1 to 6 As shown, a plurality of buckles 520 and a plurality of slideways 330 are provided. The plurality of buckles 520 are arranged at intervals along the circumference of the fixed base 500, and the plurality of slideways 330 are arranged at intervals along the circumference of the accommodating cavity 310. The plurality of buckles 520 and the plurality of slideways 330 are connected in a one-to-one correspondence.

[0062] In some embodiments, Figures 1 to 6 As shown, the floating disk box further includes a cold plate heat conductive block 600 mounted on the first end of the heat dissipation cold plate 200, and the heat dissipation cold plate 200 contacts the liquid cooling cold plate 700 through the cold plate heat conductive block 600. By arranging the cold plate heat conductive block 600 at the first end of the heat dissipation cold plate 200, the heat dissipation cold plate 200 contacts the liquid cooling cold plate 700 through the cold plate heat conductive block 600, thereby improving the heat conduction efficiency.

[0063] The present application also provides a server, such as Figures 1 to 7 As shown, it includes a chassis 800 , a liquid-cooled cold plate 700 and any of the above floating disk boxes, the liquid-cooled cold plate 700 and the floating disk box are both connected to the chassis 800 , and the first end of the heat dissipation cold plate 200 abuts against the liquid-cooled cold plate 700 .

[0064] In the above server, both the liquid-cooled cold plate 700 and the floating disk box are installed on the chassis 800, and the heat dissipation cold plate 200 of the floating disk box is in contact with the liquid-cooled cold plate 700. The elastic member 400 of the floating disk box pushes the heat dissipation cold plate 200 to move toward the liquid-cooled cold plate 700 through its own elastic force, thereby achieving close contact between the heat dissipation cold plate 200 and the liquid-cooled cold plate 700. The server of the present application solves various errors in the chassis 800 and the processing process through the elastic function of the elastic member 400, so that the heat dissipation cold plate 200 and the liquid-cooled cold plate 700 are always in full contact.

[0065] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
