Description

本考案はヒートシンクの構造に係り、特に、係止具を有し且つ構造強度を補強できるヒートシンクの構造に関る。 The present invention relates to a heat sink structure, and more particularly to a heat sink structure having a locking member and capable of reinforcing structural strength.

ヒートシンクは、発熱素子からの熱を放熱させる役割を機能している。この発熱素子は、例えば、ＣＰＵ（中央処理装置）やＧＰＵ（グラフィックスプロセッシングユニット）などであり、また、ヒートシンクに合わせてファン及び放熱フィンが設置されている。 The heat sink functions to dissipate heat from the heat generating element. This heat generating element is, for example, a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), and a fan and heat radiating fins are installed in accordance with the heat sink.

図９に従来のヒートシンクを示す。従来は、発熱素子４と固定孔３１とを有する回路板３にヒートシンク８を固定するため、ヒートシンク８の側縁部８１に複数の通し孔８１１が開設されている。これらの通し孔８１１は、締結素子８１２による固定をし易くするようにこれらの固定孔３１に対応している。これらの固定孔３１が発熱素子４の周囲に位置することで、ヒートシンク８がその側縁部８１の通し孔８１１を通じて回路板３の固定孔３１と一体に固定されることの外に、ヒートシンク８の底部側を発熱素子４にそのまま平坦に貼り付けることができる。よって、発熱素子４から生じた熱をヒートシンク８に伝達して放熱することで、発熱素子４の放熱目的を達成している。 FIG. 9 shows a conventional heat sink. Conventionally, in order to fix the heat sink 8 to the circuit board 3 having the heat generating element 4 and the fixing hole 31, a plurality of through holes 811 are formed in the side edge portion 81 of the heat sink 8. These through holes 811 correspond to these fixing holes 31 so that the fastening elements 812 can be easily fixed. Since these fixing holes 31 are located around the heat generating element 4, the heat sink 8 is fixed integrally with the fixing holes 31 of the circuit board 3 through the through holes 811 of the side edges 81. The bottom side can be flatly attached to the heating element 4 as it is. Therefore, the heat generated by the heat generating element 4 is achieved by transferring the heat generated from the heat generating element 4 to the heat sink 8 for heat dissipation.

しかしながら、上記した従来のヒートシンクの構造では、ヒートシンク８が中空胴体（内側壁面に毛細組織が設けられ）であり、通し孔８１１がヒートシンク８に直接的に開設され、締結素子８１２による固定用の外力がヒートシンク８に直接に加わるため、熱伝導の過程において応力変形の問題が発生し易くなる。ひいては放熱効率が低下するので、一般に胴体内に支持構造を増設して圧力抵抗強度を向上させる必要があるだけでなく、工程が複雑となる。 However, in the above-described conventional heat sink structure, the heat sink 8 is a hollow body (capillary structure is provided on the inner wall surface), and a through hole 811 is directly opened in the heat sink 8, so that an external force for fixing by the fastening element 812 is used. Is directly added to the heat sink 8, the problem of stress deformation is likely to occur in the process of heat conduction. As a result, since the heat radiation efficiency is lowered, it is not only necessary to increase the pressure resistance strength by adding a support structure in the body, but also the process becomes complicated.

さらに、従来のヒートシンク８は、回路板３上の発熱素子４及び発熱素子の周囲の固定孔３１に対して、ヒートシンク８の側縁部８１に対応した通し孔８１１を開設するための空間を予め保留しなければならず、しかも、１セットのヒートシンクの金具は、１種の発熱素子しか適応できないので、異なる発熱素子に対処するためにはそれぞれ対処可能なヒートシンクの金具を複数作製しなければならず、コストが嵩むといった問題がある。 Furthermore, the conventional heat sink 8 previously has a space for opening a through hole 811 corresponding to the side edge 81 of the heat sink 8 with respect to the heat generating element 4 on the circuit board 3 and the fixing hole 31 around the heat generating element. Moreover, since one set of heat sink fittings can only accommodate one type of heat generating element, in order to cope with different heating elements, it is necessary to make a plurality of heat sink fittings that can handle each of them. However, there is a problem that costs increase.

本考案は前記した問題を完全に克服するためになされたものである。 The present invention has been made to completely overcome the above-mentioned problems.

そこで本考案は、係止具とヒートシンクとの特別な構造設計により、ヒートシンクの胴体内の支持構造の代わりや、薄型化、応力変形が生じ難い効果を達できる係止具を有するヒートシンクの構造を提供することを目的とする。 Therefore, the present invention provides a heat sink structure having a locking tool that can achieve an effect that is less likely to cause stress reduction and deformation, instead of a support structure in the body of the heat sink, by a special structural design of the locking tool and the heat sink. The purpose is to provide.

さらに、本考案の次の目的は、回路板の固定孔の位置に応じてヒートシンクの対応箇所に係止具が選択的に結合されることにより、係止具の結合位置を自由に調整できるとともに、コストを低下できる係止具を有するヒートシンクの構造を提供することをとする。 Furthermore, the next object of the present invention is to freely adjust the coupling position of the latching tool by selectively coupling the latching tool to the corresponding part of the heat sink according to the position of the fixing hole of the circuit board. It is intended to provide a heat sink structure having a locking tool capable of reducing costs.

前記目的を達成するため、本考案の係止具を有するヒートシンクの構造は、ヒートシンクと係止具とを含む。前記ヒートシンクは、複数の側縁部を有し、前記ヒートシンクの一面に収納空間が設けられている。前記係止具は、弾性シートであり、前記ヒートシンクの少なくとも一方の側縁部に結合された少なくとも一つの結合部を有し、前記結合部の一部が前記収納空間に収納されている。よって、放熱面積が向上され、構造強度が補強され、応力変形が生じ難い効果を備える。 In order to achieve the above object, a heat sink structure having a locking device of the present invention includes a heat sink and a locking device. The heat sink has a plurality of side edges, and a storage space is provided on one surface of the heat sink. The locking tool is an elastic sheet, has at least one coupling portion coupled to at least one side edge of the heat sink, and a part of the coupling portion is accommodated in the storage space. Therefore, the heat dissipation area is improved, the structural strength is reinforced, and the stress deformation hardly occurs.

本考案の係止具を有するヒートシンクの構造は、前記ヒートシンクの側縁部に延伸部がさらに延伸され、前記延伸部の長さが前記結合部の長さより大きく、前記少なくとも一つの結合部が前記ヒートシンクの少なくとも一方の側縁部の延伸部に選択可能に結合されている。よって、係止具の結合位置を自由に調整できるとともに、コストが低下される効果を備える。 In the heat sink structure having the locking device according to the present invention, an extending portion is further extended to a side edge portion of the heat sink, the length of the extending portion is larger than the length of the coupling portion, and the at least one coupling portion is the The heat sink is selectively coupled to an extension of at least one side edge of the heat sink. Therefore, the coupling position of the locking tool can be freely adjusted, and the cost can be reduced.

＜第１実施例＞
図１、図２及び図２Ａに示すように、本考案に係る係止具を有するヒートシンクの構造は、ヒートシンク１と係止具２とを有する。ヒートシンク１は中空胴体であって、内部に毛細組織１０２及び稼働流体を含む。 <First embodiment>
As shown in FIGS. 1, 2, and 2 </ b> A, the structure of the heat sink having a locking device according to the present invention includes a heat sink 1 and a locking device 2. The heat sink 1 is a hollow body and includes a capillary tissue 102 and a working fluid therein.

ヒートシンク１は、複数の側縁部１１を有し、ヒートシンク１の一面に収納空間１０３が設けられている。収納空間１０３は、胴体に凹む壁面と毛細組織１０２とでともに支持構造を構成するようになっている。 The heat sink 1 has a plurality of side edge portions 11, and a storage space 103 is provided on one surface of the heat sink 1. The storage space 103 constitutes a support structure together with the wall surface recessed in the trunk and the capillary tissue 102.

係止具２は、弾性のある薄型シートであり、鉄合金、銅合金またはステンレス材で作製される。
係止具２は、二つの結合部２１（係止具２の結合部２１は、結合するための複数の孔２１３を設けており）を有する。各結合部２１は、桁２１１と複数の片持ちばり２１２とを有する。上記の両結合部２１の桁２１１は、ヒートシンク１の対向する両側縁部１１にそれぞれ結合される。各結合部２１の桁２１１は長辺を有し、これらの片持ちばり２１２は、桁２１１の長辺から延出される（例えば、斜め延出または側方向延出し、図に側方向延出を示し）。各片持ちばり２１２には孔２１３が設けられている。各結合部２１とヒートシンク１との間は、溶接や、かしめ、或いは溶接とかしめとの組み合わせによる結合であり、本実施例では溶接した場合を示す。 The locking tool 2 is an elastic thin sheet and is made of an iron alloy, a copper alloy, or a stainless material.
The locking tool 2 has two coupling parts 21 (the coupling part 21 of the locking tool 2 is provided with a plurality of holes 213 for coupling). Each connecting portion 21 includes a girder 211 and a plurality of cantilever beams 212. The girders 211 of the coupling portions 21 are coupled to the opposite side edge portions 11 of the heat sink 1. The girders 211 of each coupling part 21 have long sides, and these cantilever beams 212 are extended from the long sides of the girders 211 (for example, obliquely extended or laterally extended, with the sideways extending in the figure. Show). Each cantilever 212 is provided with a hole 213. Between each coupling part 21 and the heat sink 1, it is the coupling | bonding by welding, caulking, or the combination of welding and caulking, and the case where it welds is shown in a present Example.

また、係止具２は、上記の両結合部２１の間に接続された位置決め部２２を有する。詳細に説明すると、位置決め部２２が両結合部２１の桁２１１の間に接続される。位置決め部２２は、ヒートシンク１の上面または底面に結合されるとともに収納空間１０３内に収納される（係止具２の位置決め部２２は、Ｅ字状構造であり）。収納後の全体の高さは、ヒートシンク１と係止具２との高さの合計より小さい。図に示すように、係止具２とヒートシンク１との間をより好適な強度で結合するため、位置決め部２２が底面１０２に結合されている。 Moreover, the locking tool 2 has the positioning part 22 connected between both said coupling | bond parts 21. FIG. More specifically, the positioning portion 22 is connected between the beams 211 of both the coupling portions 21. The positioning portion 22 is coupled to the upper surface or the bottom surface of the heat sink 1 and is stored in the storage space 103 (the positioning portion 22 of the locking tool 2 has an E-shaped structure). The total height after storage is smaller than the total height of the heat sink 1 and the locking tool 2. As shown in the figure, a positioning portion 22 is coupled to the bottom surface 102 in order to couple the locking tool 2 and the heat sink 1 with more suitable strength.

図２Ａは、図２のＡ−Ａ線の断面図である。図２Ａを参照すると、結合部２１の一部と位置決め部２２とが収納空間１０３内に収納されると、ヒートシンク１の内部が支持されその構造強度が補強されるようになる。 2A is a cross-sectional view taken along line AA in FIG. Referring to FIG. 2A, when a part of the coupling portion 21 and the positioning portion 22 are stored in the storage space 103, the inside of the heat sink 1 is supported and the structural strength is reinforced.

＜第２実施例＞
図３〜図６に示すように、第２実施例に係る係止具を有するヒートシンクの構造は、ヒートシンク１と係止具２とを有する。ヒートシンク１は中空胴体である。 <Second embodiment>
As shown in FIGS. 3 to 6, the structure of the heat sink having the locking device according to the second embodiment includes a heat sink 1 and a locking device 2. The heat sink 1 is a hollow body.

ヒートシンク１は、複数の側縁部１１を有する。好ましくは、対向する両側縁部１１に図に示す延出部１１１が側方向にそれぞれ延出されている。 The heat sink 1 has a plurality of side edge portions 11. Preferably, extended side portions 111 shown in the drawing are extended in the lateral direction at opposite side edge portions 11 respectively.

係止具２は、弾性のある薄型シートであり、鉄合金、銅合金またはステンレス材で作製される。
係止具２は、二つの結合部２１を有し、各結合部２１には複数の孔２１３が設けられている。各結合部２１がヒートシンク１の各側縁部１１に結合されている。また、より大きな結合強度を備えるように各延出部１１１にさらに結合されることが好ましい。各結合部２１とヒートシンク１との間は、溶接、かしめ、或いは溶接とかしめとの組み合わせにより結合されている。本実施例では、かしめで結合した形態を示す。 The locking tool 2 is an elastic thin sheet and is made of an iron alloy, a copper alloy, or a stainless material.
The locking tool 2 has two coupling portions 21, and each coupling portion 21 is provided with a plurality of holes 213. Each coupling portion 21 is coupled to each side edge portion 11 of the heat sink 1. Moreover, it is preferable that it is further coupled to each extending portion 111 so as to have a greater coupling strength. Each coupling portion 21 and the heat sink 1 are coupled by welding, caulking, or a combination of welding and caulking. In this embodiment, a configuration in which caulking is used is shown.

各結合部２１は、桁２１１と複数の片持ちばり２１２とを有する。上記の両結合部２１の桁２１１は、ヒートシンク１の両側縁部１１の延出部１１１にそれぞれ結合される（勿論、各側縁部１１及び各側縁部１１の延出部１１１に結合されても良い）。各結合部２１の桁２１１は長辺を有する。これらの片持ちばり２１２は、桁２１１の長辺から延出される（例えば、斜め延出または側方向延出し、図に側方向延出を示し）。各片持ちばり２１２には発熱素子４の回路板３（または基板）に対応する締結構造がさらに設けられている。図５に示すように、本実施例では、締結部材２３（例えば、ねじ）の固定が必要とする孔２１３であって、回路板３の固定孔３１に対応して形成されている。また、タップ孔を有する柱体またはフック状構造であっても良い。 Each connecting portion 21 includes a girder 211 and a plurality of cantilever beams 212. The beams 211 of both the coupling portions 21 are coupled to the extending portions 111 of the side edge portions 11 of the heat sink 1 (of course, coupled to the side edge portions 11 and the extending portions 111 of the side edge portions 11. May be). The digit 211 of each connecting portion 21 has a long side. These cantilever beams 212 extend from the long side of the girder 211 (eg, diagonally or laterally extended, with the lateral extension shown in the figure). Each cantilever 212 is further provided with a fastening structure corresponding to the circuit board 3 (or substrate) of the heating element 4. As shown in FIG. 5, in this embodiment, the hole 213 is required to fix the fastening member 23 (for example, a screw), and is formed corresponding to the fixing hole 31 of the circuit board 3. Further, it may be a column having a tap hole or a hook-like structure.

図５、図６は回路板３を示す。図５、図６を参照すると、回路板３に発熱素子４と２組の固定孔３１とを有し、これらの固定孔３１が発熱素子４の周囲に位置されている。
本考案のヒートシンクの構造では、ヒートシンク１が発熱素子４に平坦に貼り付けられ、図５、図６に示すように、発熱素子４に底面で平坦に貼り付けられる。
続いて、係止具２の各結合部２１は、ヒートシンク１の各側縁部１１の延出部１１１に桁２１１により結合される（勿論、各側縁部１１及び各側縁部１１の延出部１１１に結合されても良いが、複雑にならないように、後述の実施例ではこれについて繰り返して説明しない）。
最後に、互いに重ねられた孔２１３と固定孔３１とを締結部材２３により一体に固定して、ヒートシンク１を回路板３に安定的に固定する。発熱素子４もヒートシンク１と回路板３との間に適切に位置されることによって、発熱素子４から生じた熱をヒートシンク１に伝達して放熱することができる。
そのうち、固定用の孔２１３がヒートシンク１ではなく係止具２に開設されるため、締結部材２３による固定用の力がヒートシンク１に直接に加わらず、係止具２を介してヒートシンク１の支持力のある収納空間１０３に加わられ、ヒートシンク１が応力伝達過程において変形を発生し難くなり、放熱効率も低下しなくなる。 5 and 6 show the circuit board 3. Referring to FIGS. 5 and 6, the circuit board 3 has the heating element 4 and two sets of fixing holes 31, and these fixing holes 31 are positioned around the heating element 4.
In the heat sink structure of the present invention, the heat sink 1 is affixed flat to the heat generating element 4, and as shown in FIGS.
Subsequently, each coupling portion 21 of the locking tool 2 is coupled to the extending portion 111 of each side edge portion 11 of the heat sink 1 by a girder 211 (of course, the extension of each side edge portion 11 and each side edge portion 11). Although it may be coupled to the exit portion 111, this will not be repeated in the embodiments described later so as not to be complicated).
Finally, the hole 213 and the fixing hole 31 that are overlapped with each other are integrally fixed by the fastening member 23, and the heat sink 1 is stably fixed to the circuit board 3. Since the heat generating element 4 is also appropriately positioned between the heat sink 1 and the circuit board 3, heat generated from the heat generating element 4 can be transmitted to the heat sink 1 to be dissipated.
Among them, since the fixing hole 213 is opened not in the heat sink 1 but in the locking tool 2, the fixing force by the fastening member 23 is not directly applied to the heat sink 1, and the heat sink 1 is supported via the locking tool 2. It is added to the powerful storage space 103, and the heat sink 1 is less likely to be deformed in the stress transmission process, and the heat dissipation efficiency is not lowered.

勿論、延出部１１１の長さが桁２１１より大きい場合に、各組の固定孔３１の所在位置に応じて、係止具２の各結合部２１とヒートシンク１の各側縁部１１の延出部１１１との結合位置を自由に調整できる。言い換えれば、桁２１１が延出部１１１のあらゆる部位（すなわち、結合位置）に任意に結合できる。勿論、各結合部２１の孔２１３と各組の固定孔３１とが互いに重ねられ、締結部材２３による固定をし易くなるため、当該部位もそのうちの１組の固定孔３１の所在位置に対応しなければならい。
よって、同一の金型で作製されたヒートシンク１は、異なる発熱素子４にも適用でき、従来のように異なる発熱素子４にそれぞれ対処可能なヒートシンクの金型を作製しなければならないことはなく、コストを大幅に削減できる（金型コスト及び材料コストであり、そこで、材料コストとは、係止具２がより薄い鉄合金、銅合金またはステンレス材で作製できることである）。 Of course, when the length of the extension part 111 is larger than the girders 211, the extension of each coupling part 21 of the locking tool 2 and each side edge part 11 of the heat sink 1 according to the location of the fixing holes 31 of each set. The coupling position with the protruding portion 111 can be freely adjusted. In other words, the girder 211 can be arbitrarily coupled to any part (that is, the coupling position) of the extending part 111. Of course, the hole 213 of each coupling portion 21 and each set of fixing holes 31 are overlapped with each other, and are easily fixed by the fastening member 23, so that the corresponding part also corresponds to the location of the one set of fixing holes 31. Must be.
Therefore, the heat sink 1 manufactured with the same mold can be applied to different heat generating elements 4, and there is no need to manufacture heat sink molds capable of dealing with different heat generating elements 4 as in the prior art. Cost can be greatly reduced (mould cost and material cost, where material cost is that the fastener 2 can be made of a thinner iron alloy, copper alloy or stainless steel).

＜第３実施例＞
図７は、本考案の第３実施例に係るヒートシンクの構造を示す図である。図７に示すように、ヒートシンク１は、第１実施例とほぼ同一であり、その違いは、ヒートシンク１の一方の側縁部１１に延出部１１１が延出される点である。
第３実施例の係止具２は、一つの結合部２１のみを有し、第２実施例の一つの結合部２１と似ており、その違いは、結合部２１がヒートシンク１の延出部１１１に結合される点である。 <Third embodiment>
FIG. 7 is a view showing a heat sink structure according to a third embodiment of the present invention. As shown in FIG. 7, the heat sink 1 is almost the same as that of the first embodiment, and the difference is that an extending portion 111 is extended to one side edge portion 11 of the heat sink 1.
The locking device 2 of the third embodiment has only one coupling portion 21 and is similar to the one coupling portion 21 of the second embodiment, the difference being that the coupling portion 21 is an extension portion of the heat sink 1. 111 is a point to be coupled to 111.

図示すように、第３実施例の係止具２は、一つの結合部２１を有する。結合部２１は、桁２１１と複数の片持ちばり（２１２、２１４）とを有する。桁２１１は、ヒートシンク１の一方の側縁部１１に結合される。桁２１１は両長辺を有する。これらの片持ちばり（２１２、２１４）は、両長辺から異なる方向に延出される。図に示すように、一方向に二つの片持ちばり２１２が長辺から延出される。二つの片持ちばり２１２の一部は収納空間に収納される。収納後の全体の高さは、ヒートシンクと係止具との高さの合計より小さく、他方向に片持ちばり２１４が他方の長辺から延出される。 As shown in the figure, the locking tool 2 of the third embodiment has one coupling portion 21. The coupling portion 21 has a girder 211 and a plurality of cantilever beams (212, 214). The girder 211 is coupled to one side edge 11 of the heat sink 1. The girder 211 has both long sides. These cantilevers (212, 214) extend in different directions from both long sides. As shown in the figure, two cantilever beams 212 are extended from the long side in one direction. A part of the two cantilever beams 212 is stored in the storage space. The overall height after storage is smaller than the total height of the heat sink and the locking tool, and the cantilever 214 extends in the other direction from the other long side.

好ましくは、係止具２が延出部１１１の何れか一つの選択部位に桁２１１で選択可能に結合できるように、ヒートシンク１の一方の側縁部１１に延出部１１１がさらに延出されることである。このように構成することで係止具２とヒートシンク１とを自由に結合調整可能な効果を有する。
そのうち、桁２１１と延出部１１１との間は、溶接や、かしめ、或いは溶接とかしめとの組み合わせによる結合であり、本実施例ではかしめで結合した形態を示す。 Preferably, the extension portion 111 is further extended to one side edge portion 11 of the heat sink 1 so that the locking tool 2 can be selectively coupled to any one selection portion of the extension portion 111 with the beam 211. That is. By comprising in this way, it has the effect that the latching tool 2 and the heat sink 1 can be freely couple | bonded and adjusted.
Among them, the space between the girder 211 and the extended portion 111 is a connection by welding, caulking, or a combination of welding and caulking, and in this embodiment, a form of caulking is shown.

＜第４実施例＞
図８は、本考案の第４実施例に係るヒートシンクの構造を示す図である。図７に示すように、ヒートシンク１は、第３実施例と似ており、その違いは、ヒートシンク１の二つの対向する側縁部１１に延出部１１１がそれぞれ延出され、係止具２は、三つの結合部２４を有する点である。 <Fourth embodiment>
FIG. 8 is a view showing the structure of a heat sink according to a fourth embodiment of the present invention. As shown in FIG. 7, the heat sink 1 is similar to that of the third embodiment.

本考案の係止具を有するヒートシンクの構造は、ヒートシンク１に係止具２が結合され、係止具を収納するための収納空間１０３を設けることによって、ヒートシンク１の胴体内の支持構造の代わりや、薄型化の外に、固定用となる孔２１３、２４１がヒートシンク１ではなく係止具２に開設されるので、締結部材２３による固定用の力がヒートシンク１に直接的に加わらず、ヒートシンク１は、熱伝達過程において応力変形を極めて発生し難い効果を有し、放熱効率も低下されなくなる。
ヒートシンク１の延出部１１で結合部２１、２４を固定することにより、係止具２とヒートシンク１とは、その結合位置を弾性調整可能な効果を備えるので、同一金型で作製されたヒートシンク１が異なる発熱素子４に適用できる目的を達成し、従来のように複数の異なる発熱素子４にそれぞれ対処可能なヒートシンクの金型を作製しなければならないことはなく、確かにコストが大幅に削減される効果を備える。 The structure of the heat sink having the locking device of the present invention is that the locking device 2 is coupled to the heat sink 1 and a storage space 103 for storing the locking device is provided, so that the support structure in the body of the heat sink 1 can be substituted. In addition, since the holes 213 and 241 for fixing are opened not in the heat sink 1 but in the locking member 2 in addition to thinning, the fixing force by the fastening member 23 is not directly applied to the heat sink 1, and the heat sink No. 1 has the effect of hardly generating stress deformation in the heat transfer process, and the heat dissipation efficiency is not lowered.
By fixing the coupling portions 21 and 24 with the extending portion 11 of the heat sink 1, the locking tool 2 and the heat sink 1 have an effect that the coupling position thereof can be elastically adjusted. Therefore, the heat sink manufactured with the same mold It is possible to achieve the purpose that 1 can be applied to different heating elements 4, and it is not necessary to make a heat sink mold that can deal with a plurality of different heating elements 4 as in the past, and the cost is certainly greatly reduced. The effect is provided.
