[0062] In the prior art, a server includes a housing, a motherboard, a chip holder, a chip, and a cold plate assembly. The motherboard, chip holder, chip, and cold plate assembly are arranged in the housing, the chip holder is fixed to the motherboard, the chip is arranged in the chip holder, and the cold plate assembly is arranged on the chip. The cold plate assembly includes a cold plate, a water inlet pipe, a water outlet pipe, and spring screws. The cold plate is fixed to the chip holder by spring screws. Thermal conductive material is arranged between the cold plate and the chip, and the water inlet pipe and water outlet pipe are respectively mounted on the cold plate. Cooling water flows into the cold plate from the water inlet pipe, and heat is conducted between the cold plate and the chip through the thermal conductive material. The cooling water in the cold plate removes the heat generated by the chip during operation and then flows out from the water outlet pipe. However, because the thermal conductive material added between the cold plate and the chip expel air under pressure, a local vacuum is formed between the cold plate and the chip, which makes maintenance and disassembly difficult when the cold plate assembly is disassembled.
[0063] In order to solve the above problems, an embodiment of the present invention provides a cold plate assembly and a server. After the spring screws are removed, the cold plate and the chip can be separated by using a disassembly auxiliary mechanism based on the lever principle to overcome the adhesion force between the cold plate and the chip. This facilitates maintenance and disassembly when the cold plate assembly is disassembled, and can also protect the chip from violent damage.
[0064] The cold plate assembly and the server provided by the embodiments of the present invention are described in detail below with reference to specific embodiments.
[0065] Figure 1A schematic structural diagram of a cold plate assembly provided by an embodiment of the present invention; Figure 2 A schematic diagram of the structure of a server provided in an embodiment of the present invention. Figure 2 The cold plate assembly is Figure 1 The cold plate assembly in the
[0066] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a cold plate assembly 1, comprising a cold plate 10, at least one disassembly assisting mechanism, and a plurality of spring screws 30. A chip holder 3 is fixed to a motherboard 2. The cold plate assembly 1 is detachably mounted on the chip holder 3. A chip is disposed within the chip holder 3. The cold plate assembly 1 is used to cool the chip.
[0067] A plurality of spring screws 30 are provided on the cold plate 10 , and the plurality of spring screws 30 are used to fix the cold plate 10 on the chip bracket 3 of the server.
[0068] The disassembly auxiliary mechanism includes a lever 21, which is rotatably mounted on the cold plate 10. The lever 21 has a first rod 211 and a second rod 212. The second rod 212 can abut against the chip holder 3 of the server. After the spring screw 30 is removed, the lever 21 is applied with force and rotates so that the second rod 212 separates the cold plate 10 from the chip.
[0069] The cold plate 10 is provided with a water inlet pipe 11 and a water outlet pipe 12. Cooling water flows into the cold plate 10 from the water inlet pipe 11. Heat is transferred between the cold plate 10 and the chip through the heat-conducting material. The cooling water in the cold plate 10 removes the heat generated by the chip during operation and then flows out of the water outlet pipe 12.
[0070] The shape of the cold plate 10 may be a square. In other embodiments, the shape of the cold plate 10 may also be other shapes.
[0071] The number of the spring screws 30 can be set according to actual needs. In this embodiment, the number of the spring screws 30 is four, and the four spring screws 30 fix the cold plate 10 on the chip bracket 3 of the server.
[0072] The number of the disassembly auxiliary mechanism can be one or more. One disassembly auxiliary mechanism corresponds to one spring screw 30 .
[0073] The lever 21 can be a labor-saving lever or other types of levers. In the present embodiment, the lever 21 is a labor-saving lever, and the length of the first rod 211 of the lever 21 can be greater than the length of the second rod 212.
[0074] The shape of the lever 21 can be set according to appearance requirements and the required labor-saving effect.
[0075] After the spring screw 30 is removed, the force applied to the lever 21 may be a force applied manually, or may be other forces that can cause the lever 21 to rotate.
[0076] When installing the cold plate 10, the cold plate 10, the motherboard 2, and the chip holder 3 can be placed horizontally, and the spring screws 30 can be screwed vertically downward to secure the spring screws 30 to the chip holder 3. It should be noted that the cold plate 10 is positioned opposite the chip, and a thermally conductive material is provided between the cold plate 10 and the chip.
[0077] When disassembling the cold plate 10, the cold plate 10, the main board 2 and the chip holder 3 can be placed horizontally, and the spring screw 30 is screwed vertically upward. After the spring screw 30 is disassembled, the lever 21 is exerted with force and rotates. The lever 21 rotates, and the second rod 212 moves to rotate against the chip holder 3, so that the second rod 212 separates the cold plate 10 from the chip.
[0078] In the cold plate assembly 1 provided by the embodiment of the present invention, after the spring screw 30 is removed, the lever 21 is exerted with force and rotates, so that the second rod 212 can separate the cold plate 10 from the chip, thereby facilitating maintenance and disassembly when the cold plate assembly 1 is disassembled.
[0079] It should be noted that, when the server is provided with a plurality of cold plates 10 and the cold plates 10 form a whole, the whole can also be disassembled using a disassembly auxiliary mechanism.
[0080] Figure 3 A schematic structural diagram of another cold plate assembly provided by an embodiment of the present invention; Figure 4 for Figure 3 Exploded diagram of the cold plate assembly in FIG; Figure 5 A schematic diagram of the structure of another server provided in an embodiment of the present invention, Figure 5 The cold plate assembly is Figure 3 The cold plate assembly in Figure 5 The cold plate assembly and chip holder are not installed; Figure 6 for Figure 5 Schematic diagram of the structure in which the cold plate assembly is installed on the chip holder;
[0081] Figure 7 for Figure 5 Schematic diagram of the structure when the cold plate assembly is disassembled; Figure 8 for Figure 5 Schematic diagram of the structure after the cold plate assembly is disassembled.
[0082] Alternatively, as Figure 3 and Figure 4As shown, the disassembly auxiliary mechanism also includes an elastic member 22 and a linkage member 23. The elastic member 22 is connected between the first rod 211 and the linkage member 23. The second rod 212 can abut against the chip bracket 3 of the server. The linkage member 23 is installed on the spring screw 30. The linkage member 23 can move in the axial direction of the spring screw 30 with the spring screw 30. The linkage member 23 is used to pull the first rod 211 of the lever 21 through the elastic member 22 after the spring screw 30 is disassembled, so that the second rod 212 separates the cold plate 10 from the chip.
[0083] The elastic member 22 is an elastic component. In this embodiment, the elastic member 22 can be a tension spring.
[0084] The linkage member 23 may be an oblong plate or a plate of other shapes.
[0085] like Figure 5 and Figure 6 As shown, when installing the cold plate 10, the cold plate 10, motherboard 2, and chip holder 3 can be placed horizontally. The spring screw 30 is screwed vertically downward, driving the linkage member 23 downward. The elastic member 22 is stretched by the linkage member 23, and the elastic member 22 applies a force to the first rod 211 of the lever 21. The second rod 212 of the lever 21 abuts the chip. The spring screw 30 needs to overcome the force exerted by the second rod 212 of the lever 21 on the chip holder to be fixed to the chip holder 3. It should be noted that thermal conductive material is provided between the cold plate 10 and the chip.
[0086] like Figure 7 As shown, when the cold plate 10 is disassembled, the cold plate 10, the main board 2 and the chip holder 3 can be placed horizontally, and the spring screw 30 is screwed vertically upwards, as shown in FIG. Figure 8 As shown, after the spring screw 30 is unlocked, the spring screw 30 will move upward for a distance, and the spring screw 30 drives the linkage part 23 to move upward. The elastic part 22 is stretched and lengthened by the linkage part 23, and the elastic part 22 applies a force to the first rod 211 of the lever 21. The first rod 211 is pulled, and the lever 21 rotates. The second rod 212 rotates against the chip bracket 3, so that the second rod 212 can separate the cold plate 10 from the chip.
[0087] Figure 9 for Figure 4 Schematic diagram of the cold plate structure, Figure 10 for Figure 4 Schematic diagram of the lever structure.
[0088] Alternatively, as Figure 3 、 Figure 9 and Figure 10 As shown, at least one mounting seat 101 is provided on the cold plate 10 , a rotatable shaft 13 is mounted on the mounting seat 101 , and the lever 21 further has a rotation hole 213 , through which the rotation shaft 13 can pass.
[0089] The number of the mounting seats 101 corresponds to the number of the disassembly auxiliary mechanisms. The positions of the mounting seats 101 on the cold plate 10 can be set according to actual needs.
[0090] The mounting seat 101 has a limiting groove, the lever 21 is located in the limiting groove, and a limiting wall 1011 is provided on one side of the limiting groove. The limiting wall 1011 is used to limit the rotation angle of the lever 21 to prevent the lever 21 from rotating too much and affecting the reset of the lever 21. Figure 8 The state of the lever 21 in is the initial state of the lever 21, Figure 6 The state of the lever 21 in FIG. 2 is the installation state of the lever 21 .
[0091] The rotating shaft 13 can rotate on the mounting seat 101 . The lever 21 is mounted on the rotating shaft 13 through the rotating hole 213 . The rotating hole 213 and the rotating shaft 13 are interference fit. The lever 21 rotates together with the rotating shaft 13 .
[0092] In an optional embodiment, the cold plate 10 is a square cold plate with two mounting blocks 101 disposed on the square cold plate. The two mounting blocks 101 are located on diagonals of the square cold plate, and each mounting block 101 corresponds to a disassembly assist mechanism. This arrangement allows the cold plate 10 to be fully separated from the chip by the two diagonally disposed disassembly assist mechanisms during disassembly, effectively protecting the chip.
[0093] Figure 11 for Figure 4 Schematic diagram of the structure of the linkage parts; Figure 12 for Figure 4 Exploded diagram of the spring screw in Figure 1; Figure 13 for Figure 12 Schematic diagram of the structure of the screw body; Figure 14 for Figure 12 Schematic diagram of the structure of the nut.
[0094] Alternatively, as Figure 12 、 Figure 13 and Figure 14 As shown, the spring screw 30 includes a screw body 31 and a nut 32. The screw body 31 has a nut 311 and a boss 313. A first smooth cylinder 312 is provided between the nut 311 and the boss 313. Figure 11 As shown, the linkage part 23 is provided with a screw through hole 231, and the linkage part 23 is sleeved on the first smooth cylinder 312 through the screw through hole 231. The nut 32 is screwed on the nut 311, and the linkage part 23 is arranged between the nut 32 and the boss 313 in the axial direction of the spring screw 30.
[0095] The linkage member 23 and the first smooth cylinder 312 can rotate relative to each other.
[0096] The shape of the screw through hole 231 can be circular or other shapes.
[0097] like Figure 14 As shown, the nut 32 has an internal thread 321 and a limiting step 322 . The internal thread 321 is threadedly connected to the nut 311 . The limiting step 322 is used to limit the depth of the nut 32 being screwed in.
[0098] When installing the cold plate 10, the cold plate 10, the main board 2 and the chip bracket 3 can be placed horizontally, and the spring screw 30 is screwed vertically downward. The nut 32 of the spring screw 30 applies a downward force to the linkage part 23, so that the spring screw 30 can drive the linkage part 23 to move downward.
[0099] When disassembling the cold plate 10, the cold plate 10, the main board 2 and the chip bracket 3 can be placed horizontally, and the spring screw 30 is screwed vertically upward. The nut 32 of the spring screw 30 applies an upward force to the linkage part 23, so that the spring screw 30 can drive the linkage part 23 to move upward.
[0100] Alternatively, as Figure 11 As shown, the linkage member 23 is further provided with a limiting hole 232 , and a guide column 102 is provided on the cold plate 10 , and the linkage member 23 is sleeved on the guide column 102 through the limiting hole 232 .
[0101] The limiting hole 232 may be circular or in other shapes.
[0102] The extending direction of the guide post 102 is the same as the axial direction of the spring screw 30 .
[0103] During the installation or removal process of the spring screw 30, the screw body 31 of the spring screw 30 will rotate and move in the axial direction of the spring screw 30 at the same time. Through the guide column 102, the linkage member 23 can be made to move only in the axial direction of the spring screw 30 and can prevent the linkage member 23 from rotating.
[0104] Alternatively, as Figure 12 and Figure 13 As shown, the spring screw 30 also includes a compression spring 33, a gasket 34 and a retaining ring 35. The screw body 31 also has a screw rod 315. A second smooth cylinder 314 is arranged between the screw rod 315 and the boss 313. The gasket 34 and the compression spring 33 are sleeved on the second smooth cylinder 314. The second smooth cylinder 314 is provided with a slot 3141. The retaining ring 35 is clamped on the slot 3141. The retaining ring 35 and the compression spring 33 are respectively located on both sides of the cold plate 10, and the gasket 34 is located between the cold plate 10 and the retaining ring 35.
[0105] The screw rod 315 is used for screw connection with the chip holder 3. The clamping ring 35 is located on a side of the cold plate 10 close to the chip holder 3, and the compression spring 33 is located on a side of the cold plate 10 away from the chip holder 3.
[0106] When installing the cold plate 10, the cold plate 10, the main board 2 and the chip holder 3 can be placed horizontally, and the spring screw 30 is screwed vertically downward. One end of the compression spring 33 abuts against the cold plate 10, and the other end is compressed by the boss 313. When the screw 315 is screwed to the chip holder 3, the compression of the compression spring 33 stops.
[0107] When removing the cold plate 10, the cold plate 10, mainboard 2, and chip holder 3 can be placed horizontally. The spring screw 30 is screwed vertically upward, disengaging the screw rod 315 from the chip holder 3. The screw body 31 moves upward a distance under the elastic force of the compression spring 33. It should be noted that the retaining ring 35 is used to prevent the spring screw 30 from detaching from the cold plate 10.
[0108] Alternatively, as Figure 10 and Figure 11 As shown, the elastic member 22 is a tension spring, and the first rod 211 is provided with a first fixing hole 201, and one end of the tension spring is fixed to the first fixing hole 201; the linkage member 23 is provided with a second fixing hole 233, and the other end of the tension spring is fixed to the second fixing hole 233. This arrangement allows the linkage member 23 to pull the first rod 211 of the lever 21 through the elastic member 22.
[0109] The shapes of the first fixing hole 201 and the second fixing hole 233 are not specifically set here.
[0110] The first rod 211 includes a power section 2111 and a fixed section 2112 . The fixed section 2112 is vertically connected to the power section 2111 . The first fixing hole 201 is located on the fixed section 2112 .
[0111] The second rod 212 includes a resistance section 2121 and an abutting section 2122 . The resistance section 2121 and the abutting section 2122 are connected to each other at an angle. The abutting section 2122 can abut against the chip bracket 3 of the server.
