Description

TECHNICAL FIELD

[0001] The present application relates to a heat dissipation buckle structure, in particular to a heat dissipation buckle structure that can provide a bare die form of heat source and heat sink more closely. BACKGROUND

[0002] The heat conduction component and the heat dissipation component are a common combination used to contact and conduct heat from the heat source. Generally, the heat pipe or the heat spreader is selected for the heat conduction component to evenly conduct the heat generated by the heat source to a remote place for heat dissipation. The heat pipe or the heat spreader needs to be fixed by a base or a fixing seat arranged around the heat source.

[0003] Reference Figure 1A , Figure 1B The existing heat dissipation module is shown in the figure. The existing mainboard has at least one heat source 1, and a heat sink A is arranged to contact the heat source 1 to provide heat dissipation. In order to fix the heat sink A and the heat source 1, a fixing seat 2 is arranged around the heat source 1, and the heat sink A is locked and combined with the fixing seat 2 at four corners by screwing, so that the heat sink A and the heat source 1 are closely attached for heat conduction and heat dissipation.

[0004] In order to provide high performance computing capability for electronic devices, high performance and high power chips are used. When the chip performs operation, it generates a considerable amount of heat. The traditional operation chip has a packaging shell to cover the chip inside the wall to prevent damage to the chip. As the computing performance of the chip improves, the chip generates higher temperature than the previous chip when it operates. Because the packaging shell outside the chip affects the heat dissipation and the efficiency of heat conduction to the outside, most chips have been changed to a bare die form for setting. The surface of the bare die is not protected by a packaging shell, and the surface of the bare die is not a flat surface. Therefore, when the heat sink A is fixed above the heat source 1 (bare die) and contacts the heat source 1, the locking point and the locking force must be adjusted one by one, so that the heat sink A and the heat source 1 are closely attached and prevent the locking force from being too large to cause the heat source 1 (bare die) to be crushed and broken. However, because the assembly is performed by manual or mechanical arm operation of electric screwdriver, the production line assembly operation is quite fast, so it is not possible to adjust the locking force one by one in sequence in the diagonal direction. Each fixed screw is quickly locked in place, so it is not possible to ensure that the heat sink A is completely flat on the heat source 1, and whether the locking force between the heat sink A and the heat source 1 is the appropriate locking force.

[0005] Furthermore, if the radiator A is not locked diagonally, only the four corners of the radiator A will be tightly attached to the mounting base 2. Meanwhile, the heat source 1, which is located in the center of the radiator A, will be deformed due to the downward pressure from all around the radiator A, causing the center of the radiator A to bulge upwards. This will create a gap between the center of the radiator A and the heat source 1, preventing them from fitting tightly together and forming thermal resistance. This will result in uneven heating or failure of heat conduction.

[0006] Furthermore, with traditional existing technology, after the heat sink A is fixed to the heat source 1 using a screw-locking assembly, it is easy to encounter the problem of finished and semi-finished products being mixed during the production line process. Alternatively, it is difficult for different users to determine whether the heat sink A is securely locked above the heat source 1 after installation. Users cannot judge with the naked eye whether the screw-locking assembly has been properly locked or has been loosened by others. Whether the locking force provided by the screw-locking assembly to the heat sink A and the heat source 1 is too strong or not properly locked, it is not acceptable. Therefore, if finished and semi-finished products are mixed, or if the screw-locking assembly has been disassembled without cause, it cannot be immediately judged by the naked eye. This deficiency has become a major problem that needs to be improved.

[0007] Therefore, improving the heat sink A to ensure a complete and tight fit with the heat source 1, and preventing the finished product from being accidentally disassembled by others or from being mixed with finished and semi-finished products and making it impossible to judge, are the primary goals of this industry.

[0037] The upper side of the frame body 3 has an opening 31 and an abutting portion 32, and the lower side of the frame body 3 has a plurality of supports 34 around it, the plurality of supports 34 are arranged on the side of a heat source 9, and the plurality of supports 34 jointly define a reciprocating space 33, and the reciprocating space 33 is in communication with the opening 31.

[0038] The heat sink 4 has an upper side 41 and a lower side 42, and at least one through hole 43 is provided at each corner of the heat sink 4, which penetrates the upper side 41 and the lower side 42 of the heat sink 4. The heat sink 4 is arranged in the reciprocating space 33 of the frame 3, and the upper side 41 protrudes out of the opening 31.

[0039] The heat sink 4 is fixedly combined with a fixed base, a circuit substrate or a heat-conducting component.

[0040] The plurality of screw locking components 5 are externally sleeved with elastic components 5A, which are correspondingly arranged in the plurality of through holes 43, so as to float the heat sink 4 above the heat source 9 and support the heat sink 4 to be close to the heat source 9.

[0041] The operation unit group 6A is arranged on the upper side of the heat sink 4 by screwing, welding or riveting, and is combined with the heat sink 4. The operation unit group 6A has an operation member fixing frame 6 and an operation member 8. The operation member fixing frame 6 is pivotally arranged on the upper side 41 of the heat sink 4, and has a plurality of positioning ring bodies 61 and two side edges vertically arranged with a linkage part 62. The linkage part 62 is inserted with at least one linkage member 63. The operation member 8 has a push piece 81, which is connected with a first extension rod body 82 and a second extension rod body 83. The intermediate parts of the first and second extension rod bodies 82, 83 are pivotally arranged with the plurality of positioning ring bodies 61, and can be operated and pushed by 0-180 degrees, so as to drive the ends of the first and second extension rod bodies 82, 83 to be separated or contacted with the abutting part 32 of the frame 3, so as to make the abutting part 32 not pull the heat sink 4 upward, and make the heat sink 4 contact the heat source 9 after being acted by the elastic components 5A.

[0042] The cover 7 is correspondingly arranged on the upper side of the frame 3. The cover 7 has at least one folded edge 71 vertically extended on the side edge.

[0045] The operating member fixing frame 6 further has a buffer member 64 and a limiting frame 65. The buffer member 64 is arranged between the plurality of positioning ring bodies 61 and corresponds to an extension portion 811 of the push piece 81. The limiting frame 65 has a first frame body 65A and a second frame body 65B, which are arranged in parallel to each other. The first frame body 65A has a first protrusion 651A, and the second frame body 65B has a second protrusion 651B. The first and second extension rods 82 and 83 can be correspondingly clamped between the first and second frame bodies 65A and 65B and are fixed by being clamped by the first and second protrusions 651A and 651B, so as to prevent the first and second extension rods 82 and 83 from rebounding to the original operating point.

[0046] The buffer member 64 can limit the push piece 81 from being quickly pulled from the starting point (0 degrees) to the end point (180 degrees) of the operating member 8, thereby providing a buffering function.

[0047] The heat sink 4 and the heat source 9 have a containing space therebetween. At least one heat conducting assembly, which is a heat pipe or a uniform temperature plate, can be arranged in the containing space. The heat conducting assembly is arranged by being inserted into the heat sink 4 and the heat sink 4, or is arranged by being attached to the lower side 42 of the heat sink 4 in a laminated manner to contact and combine with the heat source 9.

[0048] Please refer to Figure 5A 、 Figure 5B 、 Figure 7, The present application first supports the frame body 3 as a fulcrum at the periphery of the heat source 9, and because the heat sink 4 is positioned above the heat source 9 by the plurality of screw lock assemblies 5 penetrating the perforations 43 of the four corners of the heat sink 4, and because the plurality of screw lock assemblies 5 are externally sleeved with elastic assemblies 5A to support the heat sink 4, the upper side 41 of the heat sink 4 has a plurality of positioning columns 411 and a plurality of compression springs 412 sleeved outside the positioning columns 411, and the two ends of the compression springs 412 are respectively abutted against the upper side 41 of the heat sink 4 and the lower side of the frame body 3. The heat sink 4 is close to the heat source 9, and the heat sink 4 is mainly in the initial state of being contacted by the ends of the first and second extension rods 82, 83 of the operating member 8 against the abutting portion 32 of the frame body 3. Because the first and second extension rods 82, 83 are not straight rods, the middle part and the end segment of the first and second extension rods 82, 83 have a height difference, so that the heat sink 4 is lifted up by the action of the lever principle. When the operating member 8 is operated, the ends of the first and second extension rods 82, 83 are away from the abutting portion 32, so that the first and second extension rods 82, 83 release the heat sink 4, and the plurality of elastic assemblies 5A (see Figure 7 ) support the heat sink 4 to be close to the heat source 9. Because the heat source 9 can be in a bare crystal form, a one-time and one-time pressing force can easily cause the bare crystal form of the heat source 9 without shielding protection to be cracked. Therefore, the present application slowly releases the heat sink 4 to the heat source 9 by the operating member, which not only prevents the heat source 9 from being pressed and damaged, but also provides uniform pressing and fitting for the heat source 9 in the form of a bare crystal state with an uneven surface. At the same time, the operating member 8 can simultaneously move the cover body 7 to shield the plurality of screw lock assemblies 5 to prevent being mistakenly disassembled.
