Description

本発明は、熱部品を加熱または冷却するための熱媒体を循環させる熱媒体用管を板状のベース部材の内部に収容した伝熱板の製造方法および伝熱板に関する。   The present invention relates to a heat transfer plate manufacturing method and a heat transfer plate in which a heat medium tube for circulating a heat medium for heating or cooling a heat component is accommodated in a plate-like base member.

例えば、コンピュータの中央演算装置等の熱部品を冷却するための伝熱板は、冷却水などの冷却用熱媒体を循環させる熱媒体用管を板状のベース部材の内部に収容して構成されている。熱媒体用管は熱伝導の観点より、ベース部材に密着しているのが好ましい。例えば、特許文献１に示された伝熱板は、図６に示すように、熱伝導性プレート１００（ベース部材）に形成された溝１０１に、伸縮性チューブ１０２（熱媒体用管）を挿入して、この伸縮性チューブ１０２を他の熱伝導性プレート１０３で溝１０１内に押し込んで、伸縮性チューブ１０２を変形させて溝１０１に密着させるように構成されている。   For example, a heat transfer plate for cooling a thermal component such as a central processing unit of a computer is configured by housing a heat medium pipe for circulating a heat medium for cooling such as cooling water inside a plate-like base member. ing. The heat medium pipe is preferably in close contact with the base member from the viewpoint of heat conduction. For example, in the heat transfer plate disclosed in Patent Document 1, an elastic tube 102 (heat medium tube) is inserted into a groove 101 formed in a heat conductive plate 100 (base member) as shown in FIG. Then, the stretchable tube 102 is pushed into the groove 101 by another heat conductive plate 103, and the stretchable tube 102 is deformed to be brought into close contact with the groove 101.

When the other heat conductive plate 103 is pushed into the groove 101, a deformed portion (not shown) of the elastic tube 102 spreads outside the groove 101, thereby deforming the elastic tube 102 into a desired shape. There was a problem that could not be. Moreover, since the other heat conductive plate 103 which pushes in the elastic tube 102 is formed with one board, the pressing force which pushes in the elastic tube 102 will disperse | distribute, and the problem which requires a big pressing force was there.

The medium tube 20 is inserted (tube insertion process). At this time, the heat medium pipe 20 is inserted so as to be positioned at the center in the width direction of the concave groove 12. The cover plate 30 is inserted into the opening 12a of the groove 12 above the heat medium pipe 20 in the groove 12 (the groove closing step).

本実施形態では、熱媒体用管２０は、外径１２．７ｍｍで、厚さ１ｍｍの銅管が用いられている。そして、凹溝１２は、幅１７ｍｍで、深さ１６．７ｍｍに形成され、蓋板３０は、幅１７ｍｍで、厚さ８ｍｍに形成されている。   In the present embodiment, the heat medium pipe 20 is a copper pipe having an outer diameter of 12.7 mm and a thickness of 1 mm. The concave groove 12 has a width of 17 mm and a depth of 16.7 mm, and the cover plate 30 has a width of 17 mm and a thickness of 8 mm.

なお、ベース部材１０は、アルミニウム合金の押出形材にて構成されており、凹溝１２は押出時に形成されているが、アルミニウム合金製の平板の表面に、公知の切削加工等により半円形断面を備えた凹溝を形成するようにしてもよい。   The base member 10 is made of an extruded shape of an aluminum alloy, and the concave groove 12 is formed at the time of extrusion. A semicircular cross section is formed on the surface of a flat plate made of aluminum alloy by a known cutting process or the like. You may make it form the ditch | groove provided with.

蓋板３０を熱媒体用管２０上に挿入すると、蓋板３０は、ベース部材１０の表面１１よりも４ｍｍ突出した状態となっている。   When the cover plate 30 is inserted onto the heat medium pipe 20, the cover plate 30 is in a state of protruding 4 mm from the surface 11 of the base member 10.

その後、図１の（ｂ）に示すように、プレス機４０にセットして蓋板３０を凹溝１２の底部１２ｂ側に押圧する。本実施形態では、蓋板３０の突出部分先端がベース部材１０の表面１１と同じ高さになるまで押圧する（押圧工程）。   Thereafter, as shown in FIG. 1 (b), the cover plate 30 is set to the press machine 40 and presses the bottom plate 12 b of the groove 12. In this embodiment, it presses until the protrusion part front-end | tip of the cover board 30 becomes the same height as the surface 11 of the base member 10 (pressing process).

これによって、蓋板３０が凹溝１２の内部に押し込まれて、熱媒体用管２０が、凹溝１２の底部１２ｂとの間に挟まれ押圧されて塑性変形する。このとき、熱媒体用管２０、凹溝１２および蓋板３０が前記のような寸法および形状に設定されているので、熱媒体用管２０は、図１の（ｃ）に示すように、扁平形状に塑性変形する。また、蓋板３０の側面と凹溝１２の内側面とが面接触するとともに、蓋板３０の上面が、ベース部材１０の表面１１と面一なる。ここで、凹溝１２の内側面と蓋板３０の側面によって突合せ部Ｖ１，Ｖ２が形成される。 As a result, the cover plate 30 is pushed into the concave groove 12, and the heat medium pipe 20 is sandwiched and pressed between the bottom 12b of the concave groove 12 and plastically deformed. At this time, since the heat medium pipe 20, the concave groove 12, and the cover plate 30 are set to the above dimensions and shapes, the heat medium pipe 20 is flat as shown in FIG. Plastically deforms into shape. Further, the side surface of the cover plate 30 and the inner surface of the concave groove 12 are in surface contact, and the upper surface of the cover plate 30 is flush with the surface 11 of the base member 10. Here, the abutting portions V 1 and V 2 are formed by the inner surface of the concave groove 12 and the side surface of the lid plate 30.

このとき、熱媒体用管２０は、凹溝１２の内部に完全に収容された状態で、閉塞された空間内で蓋板３０に押圧されるので、凹溝１２の内表面に沿って変形することとなり、凹溝１２の外側に変形することはなく、所望の形状に確実に変形させることができる。したがって、熱媒体用管２０とベース部材１０とは密に接触することとなり、熱媒体用管２０とベース部材１０との接触面積が大きくなるので、伝熱板１の熱伝導性を高めることができる。また、凹溝１２が複数設けられている場合でも、蓋板３０は、一つの凹溝１２に一つずつ挿入されるので、プレス機４０と蓋板３０との接触面積を小さくできる。したがって、プレス機４０の押圧力を蓋板３０に集中的に伝達することができ、小さい押圧力で、熱媒体用管２０を変形させることができる。すなわち、プレス機４０の蓋板３０への押圧力を、熱媒体用管２０の変形に直接的に利用することで、押圧力を小さくすることができ、製造が容易になる。   At this time, the heat medium pipe 20 is pressed against the cover plate 30 in the closed space in a state of being completely accommodated in the inside of the groove 12, so that it deforms along the inner surface of the groove 12. That is, it does not deform to the outside of the concave groove 12, and can be reliably deformed into a desired shape. Therefore, the heat medium pipe 20 and the base member 10 are in close contact with each other, and the contact area between the heat medium pipe 20 and the base member 10 is increased, so that the heat conductivity of the heat transfer plate 1 can be improved. it can. Even when a plurality of the concave grooves 12 are provided, the cover plate 30 is inserted into the single concave groove 12 one by one, so that the contact area between the press machine 40 and the cover plate 30 can be reduced. Therefore, the pressing force of the press machine 40 can be transmitted intensively to the cover plate 30, and the heat medium pipe 20 can be deformed with a small pressing force. That is, by directly using the pressing force applied to the cover plate 30 of the press machine 40 for the deformation of the heat medium pipe 20, the pressing force can be reduced, and the manufacture is facilitated.

また、凹溝１２の底部１２ｂの幅方向両端の入隅部が曲面状に形成されているので、熱媒体用管２０の変形部分が凹溝１２の内表面に追従しやすく、熱媒体用管２０が凹溝１２の底部１２ｂの形状に沿って変形する。これによって、熱媒体用管２０が、凹溝１２の底部１２ｂの内表面に面接触することとなり、熱媒体用管２０とベース部材１０との密着性が高まり、伝熱板１の熱伝導性を向上することができる。   Further, since the corners at both ends in the width direction of the bottom 12b of the groove 12 are formed in a curved shape, the deformed portion of the heat medium tube 20 can easily follow the inner surface of the groove 12, and the heat medium tube 20 is deformed along the shape of the bottom 12 b of the groove 12. As a result, the heat medium pipe 20 comes into surface contact with the inner surface of the bottom portion 12b of the concave groove 12, and the adhesion between the heat medium pipe 20 and the base member 10 is enhanced, so that the heat conductivity of the heat transfer plate 1 is increased. Can be improved.

さらに、凹溝１２、熱媒体用管２０および蓋板３０は、前記したような所定寸法に形成されており、これによって、蓋板３０が、凹溝１２の開口部１２ａに挿入された際にベース部材１０の表面１１よりも突出する。そして、蓋板３０の突出部分先端をベース部材１０の表面１１まで押圧することで、熱媒体用管２０を塑性変形させるようにしたことによって、蓋板３０の押込み長さは一定に保たれるので、熱媒体用管２０の変形量管理および変形形状管理を容易に行うことができる。   Further, the concave groove 12, the heat medium pipe 20 and the lid plate 30 are formed to have the predetermined dimensions as described above, whereby when the lid plate 30 is inserted into the opening 12a of the concave groove 12. It protrudes from the surface 11 of the base member 10. The pushing length of the cover plate 30 is kept constant by pressing the tip of the protruding portion of the cover plate 30 to the surface 11 of the base member 10 to plastically deform the heat medium pipe 20. Therefore, the deformation amount management and the deformation shape management of the heat medium pipe 20 can be easily performed.

次に、図２の（ａ）に示すように、突合せ部Ｖ１，Ｖ２（図２の（ａ）中ではＶ１）に沿って、摩擦撹拌接合を順次施す（摩擦撹拌接合工程）。このとき、突合せ部Ｖ１，Ｖ２は、ベース部材１０の表面１１で目視することができるので、摩擦撹拌接合を正確な位置で確実に行うことができる。 Next, as shown in FIG. 2 (a), the butted portion V 1, V 2 along the (V 1 is in FIG. 2 (a)), successively subjected to friction stir welding (FSW process). At this time, since the butted portions V 1 and V 2 can be visually observed on the surface 11 of the base member 10, the friction stir welding can be reliably performed at an accurate position.

摩擦撹拌接合は、公知の回転ツール４５を用いて行う。回転ツール４５は、例えば、工具鋼からなり、円柱形のツール本体４６と、その底面４６ａの中心部から同心軸で垂下するピン４７とを有する。ピン４７は、先端に向けて幅狭となるテーパ状に形成されている。なお、ピン４７の周面には、その軸方向に沿って図示しない複数の小溝や径方向に沿ったネジ溝が形成されていてもよい。   Friction stir welding is performed using a known rotary tool 45. The rotary tool 45 is made of, for example, tool steel, and includes a cylindrical tool body 46 and a pin 47 that hangs down on a concentric axis from the center of the bottom surface 46a. The pin 47 is formed in a tapered shape that becomes narrower toward the tip. A plurality of small grooves (not shown) and screw grooves along the radial direction may be formed on the peripheral surface of the pin 47 along the axial direction.

摩擦撹拌接合は、ベース部材１０及び蓋板３０を図示しない冶具により拘束した状態で、各突合せ部Ｖ１，Ｖ２に高速回転する回転ツール４５を押し込み、突合せ部Ｖ１，Ｖ２に沿って移動させる。高速回転するピン４７により、その周囲のベース部材１０及び蓋板３０のアルミニウム合金材料は、摩擦熱によって加熱され流動化する。そして、この流動した物質（塑性流動材Ｑ）が、空隙部Ｐに流入する。 Friction stir welding is a state of being constrained by a jig not shown the base member 10 and the cover plate 30, pushing the rotating tool 45 rotating at a high speed to the respective butt portions V 1, V 2, along the butt portion V 1, V 2 Move. By the pins 47 rotating at high speed, the surrounding base member 10 and the aluminum alloy material of the cover plate 30 are heated and fluidized by frictional heat. Then, the fluidized material (plastic fluid material Q) flows into the gap P.

以上の工程によって、図３に示すように、突合せ部Ｖ１，Ｖ２（図１の（ｃ）参照）に沿って塑性化領域Ｗ１，Ｗ２が形成され、ベース部材１０と蓋板３０とで、熱媒体用管２０が密閉される。さらに、空隙部Ｐに塑性流動材Ｑが流入されて（図２の（ａ）参照）空隙部Ｐが充填されるため、各部材同士が密着され、熱伝導性の高い伝熱板１を形成することができる。 Through the above steps, as shown in FIG. 3, plasticized regions W 1 and W 2 are formed along the butted portions V 1 and V 2 (see FIG. 1C), and the base member 10 and the cover plate 30 are formed. Thus, the heat medium pipe 20 is sealed. Furthermore, since the plastic fluid material Q is introduced into the gap P (see FIG. 2A) and the gap P is filled, the members are brought into close contact with each other to form the heat transfer plate 1 having high thermal conductivity. can do.

また、前記したように、熱媒体用管２０の変形量管理および変形形状管理を容易に行うことができるので、熱媒体用管２０を所望の形状に塑性変形できる。したがって、熱媒体用管２０とベース部材１０との密着性をより一層高めることができ、熱伝導性をさらに高めることができる。   Further, as described above, since the deformation amount management and the deformation shape management of the heat medium pipe 20 can be easily performed, the heat medium pipe 20 can be plastically deformed into a desired shape. Therefore, the adhesiveness between the heat medium pipe 20 and the base member 10 can be further enhanced, and the thermal conductivity can be further enhanced.

さらに、本実施形態によれば、ベース部材１０が伝熱板１の厚さ方向全体に亘って一体に形成されているので、特許文献１のように、上面と下面とが別部材で形成されたものと比較して、熱を伝熱板１の全体に亘って一様に伝達することができる。   Furthermore, according to this embodiment, since the base member 10 is integrally formed over the entire thickness direction of the heat transfer plate 1, the upper surface and the lower surface are formed as separate members as in Patent Document 1. As compared with the above, heat can be transmitted uniformly over the entire heat transfer plate 1.

また、以上のような伝熱板１によれば、熱媒体用管２０を扁平形状に塑性変形させているので、熱媒体の流量に対して熱媒体用管２０の表面積を大きくすることができ、熱伝導性をより一層高めることができる。   Further, according to the heat transfer plate 1 as described above, since the heat medium pipe 20 is plastically deformed into a flat shape, the surface area of the heat medium pipe 20 can be increased with respect to the flow rate of the heat medium. The thermal conductivity can be further increased.

さらに、本実施形態では、断面円形の熱媒体用管２０を凹溝１２内に挿入した後に変形させているので、熱媒体用管２０の加工を容易に行うことができる。すなわち、一つの伝熱板で凹溝が複数形成されている場合は、熱媒体用管は各凹溝を繋ぐように平面視Ｓ字状に形成されることとなるが、扁平形状に形成された熱媒体用管をＳ字状に変形するのは困難である。しかし、本実施形態に係る伝熱板の製造方法では、断面円形の熱媒体用管を、Ｓ字状に変形した後に、凹溝内で塑性変形するので、平面視Ｓ字状の扁平形状の熱媒体管を容易に形成することができる。   Furthermore, in this embodiment, since the heat medium pipe 20 having a circular cross section is deformed after being inserted into the concave groove 12, the heat medium pipe 20 can be easily processed. That is, when a plurality of concave grooves are formed with one heat transfer plate, the heat medium pipe is formed in an S shape in plan view so as to connect the concave grooves, but is formed in a flat shape. It is difficult to deform the heat medium pipe into an S shape. However, in the heat transfer plate manufacturing method according to the present embodiment, the heat medium pipe having a circular cross section is plastically deformed in the concave groove after being deformed into an S shape. The heat medium tube can be easily formed.

また、ベース部材１０と蓋板３０とが、塑性化領域Ｗ１，Ｗ２において、両者の金属材料が摩擦撹拌接合により塑性流動化されるとともに、流動化された塑性流動材Ｑが空隙部Ｐに流入されているので、ベース部材１０と蓋板３０とを接合するとともに、空隙部Ｐを埋めることができる。また、摩擦撹拌接合の際に、熱媒体用管２０は、後記する回転ツールのツール本体（ジョルダ）の底面によって加圧されるので、凹溝１２の底部１２ｂとの接触性を高めることができる。これにより、熱媒体用管２０中を循環する熱媒体からの熱エネルギーを、ベース部材１０に効率よく伝達することができる。 Further, when the base member 10 and the cover plate 30 are plasticized in the plasticized regions W 1 and W 2 , both metal materials are plastically fluidized by friction stir welding, and the fluidized plastic fluidized material Q is the gap portion P. Therefore, the base member 10 and the cover plate 30 can be joined and the gap P can be filled. Further, during the friction stir welding, the heat medium tube 20 is pressurized by the bottom surface of the tool body (Jorda) of the rotary tool described later, so that the contact property with the bottom 12b of the concave groove 12 can be enhanced. . Thereby, the heat energy from the heat medium circulating in the heat medium pipe 20 can be efficiently transmitted to the base member 10.

次に、本発明を実施するための第二の最良の形態について、図面を適宜参照しながら詳細に説明する。   Next, a second best mode for carrying out the present invention will be described in detail with reference to the drawings as appropriate.

図４および図５に示すように、第二の実施形態に係る伝熱板１の製造方法は、蓋板３０が、アルミニウム合金製の押出形材に代えて、鉄製治具３１によって構成されていることを特徴とする。   As shown in FIGS. 4 and 5, in the method of manufacturing the heat transfer plate 1 according to the second embodiment, the lid plate 30 is configured by an iron jig 31 instead of the extruded shape made of aluminum alloy. It is characterized by being.

鉄製治具３１は、熱媒体用管２０を押圧する際の蓋板として利用されるものであって、その下面には、円弧状の凹部３１ａが形成されている。凹部３１ａは、所定の曲率半径で形成されており、熱媒体用管の上端部が円滑な曲面状に塑性変形するように構成されている。また、鉄製治具３１は、凹溝１２の幅寸法よりも僅かに小さい幅寸法を有している。さらに、鉄製治具３１は、第一の実施形態のアルミニウム合金製の押出形材からなる蓋板３０と同様に、熱媒体用管２０の上部で凹溝１２内に挿入したときに、鉄製治具３１が、ベース部材１０の表面１１よりも突出するような寸法を有している。   The iron jig 31 is used as a cover plate when the heat medium pipe 20 is pressed, and an arcuate recess 31a is formed on the lower surface thereof. The recess 31a is formed with a predetermined radius of curvature, and is configured such that the upper end of the heat medium pipe is plastically deformed into a smooth curved surface. The iron jig 31 has a width dimension slightly smaller than the width dimension of the concave groove 12. Further, when the iron jig 31 is inserted into the concave groove 12 at the upper part of the heat medium pipe 20 in the same manner as the cover plate 30 made of the aluminum alloy extruded profile of the first embodiment, the iron jig 31 The tool 31 has a dimension that protrudes from the surface 11 of the base member 10.

本実施形態に係る製造方法で伝熱板１を製造するに際しては、図４の（ａ）に示すように、まず、ベース部材１０の表面１１に開口して形成された凹溝１２に、熱媒体用管２０を挿入して（管挿入工程）、凹溝１２内の熱媒体用管２０上部の凹溝１２の開口部１２ａに鉄製治具３１（蓋板３０）を挿入する（凹溝閉塞工程）。   When the heat transfer plate 1 is manufactured by the manufacturing method according to the present embodiment, first, as shown in FIG. 4A, first, heat is applied to the concave grooves 12 formed in the surface 11 of the base member 10 so as to open. The medium tube 20 is inserted (tube insertion step), and an iron jig 31 (lid plate 30) is inserted into the opening 12a of the groove 12 above the heat medium tube 20 in the groove 12 (groove blockage). Process).

このとき、鉄製治具３１は、ベース部材１０の表面１１よりも突出している。なお、鉄製治具３１は、凹溝１２よりも小さい幅寸法で形成されているので、熱媒体用管２０の上部に載置するだけでよい。   At this time, the iron jig 31 protrudes from the surface 11 of the base member 10. In addition, since the iron jig 31 is formed with a width dimension smaller than that of the concave groove 12, it only needs to be placed on the upper part of the heat medium pipe 20.

その後、図４の（ｂ）に示すように、プレス機４０にセットして鉄製治具３１を凹溝１２の底部１２ｂ側に押圧する（押圧工程）。本実施形態では、鉄製治具３１は、４トンの荷重をかけて、鉄製治具３１の突出部分先端がベース部材１０の表面１１と同じ高さになるまで押圧する。これによって、鉄製治具３１が凹溝１２の内部に押し込まれて、熱媒体用管２０が、鉄製治具３１と凹溝１２の底部１２ｂとの間に挟まれて押圧され扁平形状に塑性変形する。このとき、鉄製治具３１の下面には、凹部３１ａが形成されているので、熱媒体用管２０は凹部３１ａに沿って変形し、塑性変形が円滑に行われる。なお、凹部３１ａは、一定曲率に限定されるものではなく、曲率が徐々に変化する楕円形状等の他の形状であってもよいのは勿論である。   Thereafter, as shown in FIG. 4B, the iron jig 31 is set to the bottom 12b side of the recessed groove 12 by pressing the iron jig 31 (pressing step). In the present embodiment, the iron jig 31 applies a load of 4 tons and presses the tip of the protruding portion of the iron jig 31 until it has the same height as the surface 11 of the base member 10. As a result, the iron jig 31 is pushed into the groove 12, and the heat medium pipe 20 is sandwiched and pressed between the iron jig 31 and the bottom 12b of the groove 12 to be plastically deformed into a flat shape. To do. At this time, since the recess 31a is formed on the lower surface of the iron jig 31, the heat medium pipe 20 is deformed along the recess 31a, and plastic deformation is smoothly performed. In addition, the recessed part 31a is not limited to a fixed curvature, Of course, other shapes, such as an elliptical shape from which a curvature changes gradually, may be sufficient.

プレス機４０による鉄製治具３１の押圧が完了したならば、図４の（ｃ）に示すように、鉄製治具３１を凹溝１２から取り出して、別途の蓋板３２を凹溝１２内に挿入する（蓋板挿入工程）。この蓋板３２は、断面矩形を呈しており、凹溝１２の幅寸法と同等の幅寸法と、鉄製治具３１の凹部３１ａの中央部と上面との厚さ寸法（最も薄い部分の寸法）と同等の厚さ寸法を有しており、凹溝１２に嵌合されることとなる。そして、凹溝１２に嵌合された蓋板３２は、その上面が、ベース部材１０の表面１１と面一となるとともに、蓋板３２の側面と凹溝１２の内側面とが面接触する。ここで、凹溝１２の内側面と蓋板３２の側面によって突合せ部Ｖ１，Ｖ２が形成される。 When the pressing of the iron jig 31 by the pressing machine 40 is completed, the iron jig 31 is taken out from the concave groove 12 and a separate cover plate 32 is placed in the concave groove 12 as shown in FIG. Insert (cover plate insertion step). The lid plate 32 has a rectangular cross section, a width dimension equivalent to the width dimension of the recessed groove 12, and a thickness dimension (dimension of the thinnest part) between the central portion and the upper surface of the recess 31 a of the iron jig 31. And has a thickness dimension equivalent to that of the concave groove 12. The top surface of the cover plate 32 fitted in the groove 12 is flush with the surface 11 of the base member 10, and the side surface of the cover plate 32 and the inner surface of the groove 12 are in surface contact. Here, the abutting portions V 1 and V 2 are formed by the inner side surface of the groove 12 and the side surface of the cover plate 32.

以下の工程は、第一の実施形態と同様である。図５の（ｂ）に示すように、突合せ部Ｖ１，Ｖ２（図５の（ｂ）中ではＶ１）に沿って、摩擦撹拌接合を順次施す（摩擦撹拌接合工程）。これによって、突合せ部Ｖ１，Ｖ２の周囲のベース部材１０及び蓋板３２のアルミニウム合金材料が、摩擦熱によって加熱され流動化して、この流動した物質（塑性流動材Ｑ）が、空隙部Ｐに流入する。このとき、蓋板３２は、断面矩形であって、その下面が平面状であるので、熱媒体用管２０との間に形成される空隙部Ｐは、凹溝１２の内側面に繋がる。すなわち、凹部３１ａを有する鉄製治具３１で熱媒体用管２０を押圧させて、熱媒体用管２０の上面の円弧状に形成し、その上部に平板状の蓋板３２を載置したことによって、空隙部Ｐが凹溝１２の内側面に確実に繋がる。したがって、塑性流動材Ｑが、空隙部Ｐに確実に流入して、各部同士の密着性が高まり、伝熱板１の熱伝導性を高めることができる。 The following steps are the same as in the first embodiment. As shown in FIG. 5 (b), along the butt portion V 1, V 2 (V 1 is in (b) of FIG. 5), successively subjected to friction stir welding (FSW process). As a result, the base member 10 around the butt portions V 1 and V 2 and the aluminum alloy material of the cover plate 32 are heated and fluidized by frictional heat, and the fluidized material (plastic fluid material Q) becomes the void portion P. Flow into. At this time, since the lid plate 32 has a rectangular cross section and its lower surface is flat, the gap P formed between the cover plate 32 and the heat medium pipe 20 is connected to the inner surface of the groove 12. That is, by pressing the heat medium pipe 20 with the iron jig 31 having the recess 31a to form an arc shape on the upper surface of the heat medium pipe 20, and placing the flat cover plate 32 on the upper part. The gap P is reliably connected to the inner surface of the groove 12. Therefore, the plastic fluid material Q surely flows into the gap P, the adhesion between the respective parts is increased, and the thermal conductivity of the heat transfer plate 1 can be increased.

以上の工程によって、第一の実施形態と略同様の構成の伝熱板１が製造される（図５の（ｃ）参照）。本実施形態では、第一の実施形態で得られる作用効果の他に、以下のような作用効果が得られる。要するに、本実施形態では、底面に曲面状の凹部３１ａが形成された鉄製治具３１を用いて、熱媒体用管２０を押圧しているので、熱媒体用管２０の上面が凹部３１ａに沿って円滑に変形され、変形形状を管理しやすくなる。また、熱媒体用管２０の上面中央部が内側に凹まないので、熱媒体用管２０と蓋板３２との間に塑性流動材Ｑを確実に流入させることができ、各部材同士の密着性を高めることができる。   Through the above steps, the heat transfer plate 1 having substantially the same configuration as that of the first embodiment is manufactured (see FIG. 5C). In the present embodiment, in addition to the operational effects obtained in the first embodiment, the following operational effects are obtained. In short, in the present embodiment, since the heat medium pipe 20 is pressed using the iron jig 31 having the curved concave portion 31a formed on the bottom surface, the upper surface of the heat medium pipe 20 extends along the concave portion 31a. Therefore, it is easy to manage the deformed shape. Further, since the central portion of the upper surface of the heat medium pipe 20 is not recessed inward, the plastic fluid material Q can surely flow between the heat medium pipe 20 and the cover plate 32, and the adhesiveness between the members. Can be increased.

以上、本発明の実施形態について説明したが、本発明は前記実施形態に限定されることなく、その趣旨を逸脱しない範囲で適宜に設計変更が可能である。例えば、前記実施形態では、一つの伝熱板１に一列の凹溝１２が設けられているが、凹溝を複数設けてもよいのは勿論である。   The embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the spirit of the present invention.
