[0001] The present disclosure relates to the field of heat dissipation, and in particular to a heat dissipation device having a heat conducting block arranged on a heat pipe. Background Art

[0002] In accordance with modern needs, computers and various electronic devices are developing rapidly and their performance is constantly improving. However, in the process, the heat dissipation problem brought by high-performance hardware also comes along. Generally speaking, computers and various electronic devices usually use heat dissipation components to dissipate heat, such as using thermal paste or heat sinks to attach to the electronic components to be dissipated to absorb and dissipate the heat.

[0003] However, the above heat dissipation methods have limited effects, so the industry has developed heat dissipation components using heat pipes and fins. This type of heat dissipation component mainly achieves the purpose of heat dissipation by increasing the contact area between the fins and heat pipes and the air. However, when faced with a large amount of heat energy generated by a high-power processor (such as a GPU), such a heat dissipation component still cannot maintain effective and consistent heat dissipation, resulting in poor overall heat dissipation efficiency.

[0004] Therefore, how to provide a heat dissipation device that can solve the above problems is one of the issues that the industry needs to overcome urgently. Utility Model Content

[0064] The following describes the implementation of the present disclosure by means of specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification, and can also implement or apply the present disclosure by means of other different embodiments.

[0065] See also Figures 1 to 5 The heat dissipation device 100 disclosed in the present invention includes a fin unit 1, a heat pipe group 2, a heat dissipation unit 3, four heat conduction blocks 4, two fin brackets 5 and a copper sheet 6.

[0066] The fin unit 1 has a first side 1a and a second side 1b opposite to each other, and includes a first fin group 11 and a second fin group 12 spaced apart from each other. The first fin group 11 is a structure formed by a plurality of fins arranged at intervals, and has two first grooves 111 formed by depressions from the first side 1a, a depression area 112 formed by depressions from the second side 1b, and two first through holes 113 passing through its front and rear sides. The extension direction of the first groove 111 is the same as the fin arrangement direction of the first fin group 11. The depression area 112 may be stepped, but the present disclosure is not limited thereto. The two first through holes 113 are spaced apart from each other, and may specifically have a circular cross-section. The second fin group 12 is a structure formed by a plurality of fins arranged at intervals, and has two second grooves 121 formed by depressions from the first side 1a and two second through holes 122 passing through its front and rear sides. The extension direction of the second groove 121 is the same as the fin arrangement direction of the second fin group 12. The two second through holes 122 are spaced apart from each other and may specifically have a circular cross-section.

[0067] The heat pipe group 2 is partially disposed in the recessed area 112, partially penetrates the fin unit 1, and partially exposed on the first side 1a. Figure 6 The heat pipe group 2 has two first heat pipes 21 and two second heat pipes 22. Each first heat pipe 21 has a first front through-hole 211, a first front bending portion 212, a first extension portion 213, a first flat portion 214, a first rear bending portion 215 and a first rear through-hole 216 connected in sequence. One end of the first extension portion 213 is connected to the first front through-hole 211 via the first front bending portion 212, and the other end is connected to one end of the first flat portion 214, so that the first extension portion 213, the first front bending portion 212 and the first front through-hole 211 are roughly U-shaped as a whole. The other end of the first flat portion 214 is connected to the first rear through-hole 216 via the first rear bending portion 215, so that the first flat portion 214, the first rear bending portion 215 and the first rear through-hole 216 are roughly S-shaped as a whole. The extending directions of the first flat portion 214 , the first extending portion 213 , the first front penetration portion 211 and the first rear penetration portion 216 are parallel to each other.

[0068] The first front penetration portion 211 is accommodated in the first groove 111 and is roughly tubular. The first front bending portion 212 is exposed on the first fin group 11. The first extension portion 213 is accommodated in the recessed area 112, for example, accommodated in a stepped structure (for example, a groove having a shape consistent with the first extension portion 213) in the recessed area 112, and is roughly tubular, and each first extension portion 213 is arranged side by side with each other. The first flat portion 214 is accommodated in the recessed area 112, for example, accommodated in another stepped structure (for example, in a planar shape) in the recessed area 112. At this time, the first extension portion 213 can be bent to connect the first flat portion 214 to fit the junction of the stepped structure, but the present disclosure is not limited to this. The cross-section of the first flat portion 214 is square, and each first flat portion 214 is attached to each other and accommodated side by side in the recessed area 112. The first rear bending portion 215 is exposed between the first fin set 11 and the second fin set 12. The first rear penetration portion 216 is penetrated through the second through hole 122 and is roughly in the shape of a circular tube.

[0069] Each second heat pipe 22 has a second front penetration portion 221, a second front bending portion 222, a second extension portion 223, a second flat portion 224, a second rear bending portion 225 and a second rear penetration portion 226 connected in sequence. One end of the second extension portion 223 is connected to the second front penetration portion 221 via the second front bending portion 222, and the other end is connected to one end of the second flat portion 224, so that the second extension portion 223, the second front bending portion 222 and the second front penetration portion 221 are generally U-shaped. The other end of the second flat portion 224 is connected to the second rear penetration portion 226 via the second rear bending portion 225, so that the second flat portion 224, the second rear bending portion 225 and the second rear penetration portion 226 are generally S-shaped. The extension directions of the second flat portion 224, the second extension portion 223, the second front penetration portion 221 and the second rear penetration portion 226 are parallel to each other.

[0070] The second front penetration portion 221 penetrates the first through hole 113 and is roughly in the shape of a circular tube. The second front bent portion 222 is exposed outside the first fin group 11. The second extension portion 223 is accommodated in the recessed area 112, for example, accommodated in a stepped structure (for example, a groove having a shape that matches the second extension portion 223) in the recessed area 112, and is roughly in the shape of a circular tube, and each second extension portion 223 is arranged side by side on the outside of the first extension portion 213. The second flat portion 224 is accommodated in the recessed area 112, for example, accommodated in another stepped structure (for example, in the shape of a plane) in the recessed area 112. At this time, the second extension portion 223 can be bent to connect the second flat portion 224 to fit the junction of the stepped structure, but the present disclosure is not limited to this. The cross-section of the second flat portion 224 is square, and each second flat portion 224 is attached to and arranged side by side on the outside of the first flat portion 214, and is accommodated in the recessed area 112. The second rear bending portion 225 is exposed between the first fin set 11 and the second fin set 12. The second rear penetrating portion 226 is received in the second groove 121 and is roughly in the shape of a circular tube.

[0071] In one embodiment, the heat pipe assembly 2 is made of copper.

[0072] In one embodiment, the fin arrangement directions of the first fin set 11 and the second fin set 12 are the same as the heat pipe extension directions of the first front penetration portion 211 , the first rear penetration portion 216 , the second front penetration portion 221 and the second rear penetration portion 226 .

[0073] Please also read Figure 7 and Figure 8 The heat dissipation unit 3 is arranged on the first side 1a of the fin unit 1, and includes three fans 31, three fan ports 32 and four openings 33. The fans 31 are respectively arranged in the fan ports 32 and are spaced apart from each other, and are used to generate airflow flowing through the fin unit 1. The openings 33 are respectively located between any two fan ports 32 and are spaced apart from each other. Four heat-conducting blocks 4 are spaced apart from each other on the first side 1a of the fin unit 1, and are respectively exposed to the openings 33, that is, each heat-conducting block 4 is also located between any two fans 31. The heat-conducting block 4 has a main body 41, a plurality of fin bodies 42 and an arc-shaped body 43. The main body 41 is roughly a triangular plate body. The fin bodies 42 are formed by extending outwards from one side of the main body 41 and spaced apart from each other, and the gaps between the fin bodies 42 are connected to the fan ports 32, so that the airflow generated by the fans 31 can flow through the fin unit 1 and between each fin body 42. The arc-shaped body 43 is formed by extending outwards from the other side of the main body 41. The arcuate bodies 43 of the heat conducting block 4 are respectively attached to the first front penetration parts 211 exposed in the first groove 111, and the arcuate bodies 43 are accommodated in the first groove 111. The arcuate bodies 43 are also attached to the second rear penetration parts 226 exposed in the second groove 121, and the arcuate bodies 43 are accommodated in the second groove 121.

[0074] In this embodiment, the heat conducting block 4 is triangular in shape as a whole and roughly matches the cross section of the opening 33. The heat conducting block 4 is made of heat conductive plastic to absorb the heat energy of the first front through-hole 211 and the second rear through-hole 226, so that the airflow can take away the heat energy when flowing through the fin bodies 42. In this embodiment, the curvature of the arcuate body 43 roughly matches the curvature of the first front through-hole 211 and the second rear through-hole 226, so that the arcuate body 43 can be completely attached to the first front through-hole 211 and the second rear through-hole 226.

[0075] Two fin brackets 5 are fixed to the bottom sides of the first fin group 11 and the second fin group 12 at intervals to fix the first fin group 11 and the second fin group 12 together. One side of the copper sheet 6 contacts the first flat portion 214 and the second flat portion 224, and the other side contacts a heat source (such as a display chip) to transfer the heat energy generated by the heat source to the fin unit 1, the heat pipe group 2 and the heat conductive block 4, and perform heat dissipation through the heat dissipation unit 3.

[0076] In summary, the heat dissipation device disclosed herein not only has a fin unit, a heat pipe group and a heat dissipation unit, but also has a heat conduction block between the fin unit and the heat dissipation unit that contacts the heat pipe group, which can effectively enhance the heat dissipation performance. Furthermore, the heat conduction block can be set in the fragmented space between the fans, which can enhance the heat dissipation performance without increasing the overall size of the heat dissipation device disclosed herein.

[0077] The above embodiments are only used to illustrate the technical principles, features and effects of the present disclosure, and are not intended to limit the scope of implementation of the present disclosure. Those skilled in the art can modify and change the above embodiments without violating the spirit and scope of the present disclosure.
