Abstract

[0002] At present, commonly used radiators mainly include heat dissipation fins, heat pipes and heat spreaders, and the heat pipes are vertically arranged in multiple fins.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0042] The present embodiment provides a heat sink, which includes a heat sink 100, a first heat conduction unit 200, and a second heat conduction unit 300. The heat sink 100 includes a first heat dissipation component 110 and a second heat dissipation component 120, which are arranged opposite to each other along the Z direction (first direction), and a receiving groove 111 is arranged on the opposite end faces of the first heat dissipation component 110 and / or the second heat dissipation component 120, and the first heat conduction unit 200 is arranged in the receiving groove 111, so that the first heat conduction unit 200 is hidden between the first heat dissipation component 110 and the second heat dissipation component 120, which is conducive to improving the aesthetics of the appearance of the heat sink, and at the same time, the first heat conduction unit 200 contacts the side wall of the receiving groove 111 to increase the heat conduction area, which is conducive to improving the heat dissipation effect. The heat sink 100 is provided with a through hole 130 extending in the Z direction, a part of the second heat conducting unit 300 is penetrated in the through hole 130, and a part of the first heat conducting unit 200 is in contact with the second heat conducting unit 300, and the second heat conducting unit 300 is configured to absorb heat from the heating element. When the heat sink is working, the second heat conducting unit 300 is first used to absorb heat from the heating element, and then the heat is conducted to the heat sink 100 through the first heat conducting unit 200 to achieve heat dissipation. The heat sink structure divides the heat conduction process to the heat sink 100 into two parts by using the first heat conducting unit 200 and the second heat conducting unit 300, thereby shortening the heat conduction distance of the first heat conducting unit 200 and the second heat conducting unit 300, which helps to improve the heat dissipation efficiency.
[0043] Specifically, the accommodating groove 111 is provided on both the first heat dissipation component 110 and the second heat dissipation component 120, and the accommodating grooves 111 on the first heat dissipation component 110 and the second heat dissipation component 120 cooperate to form a cross-sectional shape for accommodating the first heat conduction unit 200, so as to completely clamp the first heat conduction unit 200 between the first heat dissipation component 110 and the second heat dissipation component 120. Of course, in other embodiments, the accommodating groove 111 may be provided on the first heat dissipation component 110 alone, or may be provided on the second heat dissipation component 120 alone.
[0044] The facing surfaces of the first heat dissipation component 110 and the second heat dissipation component 120 are in surface contact, which is beneficial to heat conduction between the first heat dissipation component 110 and the second heat dissipation component 120, thereby improving the temperature balance between the first heat dissipation component 110 and the second heat dissipation component 120, and helping to improve the heat dissipation effect of the radiator.
[0045] The detailed structure of the first heat dissipation component 110 is now described with reference to the drawings.
[0046] The first heat dissipation component 110 includes a solid part 112 and fins 113. The receiving groove 111 is arranged on the solid part 112, and the fins 113 are arranged on the solid part 112, and the fins 113 extend along the Z direction. Along the extension direction of the solid part 112, the fins 113 are arranged in parallel and at intervals, so that the solid part 112 is used to absorb heat, and the fins 113 achieve the effect of rapid heat dissipation.
[0047] The entity part 112 includes a central body 1121 and a plurality of dispersed bodies 1122. The through hole 130 is arranged on the central body 1121 along the Z direction, and the plurality of dispersed bodies 1122 are arranged at intervals along the circumference of the central body 1121. One end of the dispersed body 1122 is connected to the central body 1121 and extends in a direction away from the central body 1121. The fins 113 are arranged on the dispersed bodies 1122 in parallel and at intervals along the extension direction of the dispersed bodies 1122, that is, the entity part 112 is equivalent to a skeleton for supporting the fins 113, which helps to improve the structural stability of the radiator. It can be understood that the more fins 113 there are, the better the heat dissipation effect. Therefore, the arrangement of the plurality of dispersed bodies 1122 can increase the area where the fins 113 are arranged, thereby increasing the heat dissipation area of the radiator and improving the heat dissipation effect.
[0048] In addition, fins 113 are respectively provided along the circumference of the central body 1121, along the mutually perpendicular X direction (second direction) and Y direction (third direction). Specifically, along the X direction, fins 113 are respectively provided on both sides of the central body 1121 and are arranged in parallel and spaced apart along the Y direction, and along the Y direction, fins 113 are respectively provided on both sides of the central body 1121 and are arranged in parallel and spaced apart along the X direction, thereby increasing the number of fins 113 and further improving the heat dissipation effect of the radiator.
[0049] The far ends of the fins 113 on two adjacent dispersion bodies 1122 are spaced apart to form a heat dissipation gap 114. The heat dissipation gap 114 extends radially along the center body 1121, and is evenly spaced along the circumference of the center body 1121, so that the first heat dissipation component 110 can be divided into multiple heat dissipation areas through the heat dissipation gaps, thereby simplifying the structure of the first heat dissipation component 110 and facilitating processing.
[0050] Optionally, the first heat dissipation assembly 110 and the second heat dissipation assembly 120 have the same structure.
[0051] The first heat dissipation component 110 and the second heat dissipation component 120 are formed by extrusion of a mold, which is beneficial to reducing processing costs. At the same time, since the extension direction of the through hole 130 is the same as the extension direction of the fin 113, when processing the first heat dissipation component 110 and the second heat dissipation component 120, the through hole 130 can be processed and formed at the same time, reducing the processing steps of post-drilling, thereby simplifying the processing steps.
[0052] The thickness of the fin 113 is 0.4mm-0.8mm, thereby improving the heat conduction efficiency of the fin 113, the spacing between two adjacent fins 113 is 2mm-4mm, the thickness of the solid part 112 along the Z direction is 3mm-10mm, so as to facilitate the extrusion of the profile, and the gap between adjacent fins 113 is conducive to providing sufficient heat dissipation channels and heat conduction channels to ensure heat dissipation efficiency. The heat dissipation height of the fin 113 is 4mm-20mm, which is conducive to reducing the external dimensions of the radiator and thus reducing the volume.
[0053] The second heat conducting unit 300 includes a first heat pipe 310 and a heat leveling plate 320. The first heat pipe 310 is inserted into the through hole 130. The heat leveling plate 320 is disposed at one end of the first heat pipe 310, and the end surface of the heat leveling plate 320 abuts against one side of the heat sink 100, thereby forming a process from heat absorption to heat conduction of the second heat conducting unit 300. At the same time, when the first heat pipe 310 is inserted into the through hole 130, the outer wall of the first heat pipe 310 can contact the side wall of the through hole 130, so that the first heat pipe 310 can conduct heat to the first heat conducting unit 200 on the one hand, and can directly conduct heat to the heat sink 100 on the other hand, which is conducive to increasing the heat conduction area and improving the heat conduction effect.
[0054] The wall thickness of the first heat pipe 310 is 0.2 mm to 3 mm, and the thickness of the heat-dissipating plate 320 is 1 mm to 10 mm, so as to ensure the heat conduction and heat absorption effects. Of course, in other embodiments, the user can also selectively set according to the heat source.
[0055] The first heat conduction unit 200 includes a plurality of second heat pipes 210, which are arranged along the circumference of the first heat pipe 310. Parts of the second heat pipes 210 abut against the outer diameter of the first heat pipe 310 so that the second heat pipes 210 are in full contact with the first heat pipe 310, thereby improving the heat conduction effect.
[0056] Specifically, the second heat pipe 210 includes a heat absorbing portion 211 and two heat conducting portions 212. The heat absorbing portion 211 abuts against the outer diameter of the first heat pipe 310 to achieve heat conduction from the first heat pipe 310 to the heat absorbing portion 211. The two heat conducting portions 212 are respectively connected to the two ends of the heat absorbing portion 211 and extend in a direction away from the heat absorbing portion 211. The two heat conducting portions 212 and the heat absorbing portion 211 are set at an angle to achieve large-area heat dissipation to the heat sink 100, so as to improve the heat dissipation effect of the radiator.
[0057] Along the direction away from the heat absorption part 211 , the distance between the two heat conducting parts 212 gradually increases, so that the two heat conducting parts 212 extend in a trumpet shape, thereby expanding the heat conducting range of the heat conducting parts 212 and improving the heat conducting effect.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the utility model.
