Description
本發明係有關於一種用於例如熱交換器及加熱機器或冷卻機器的傳熱板的製造方法。The present invention relates to a method of manufacturing a heat transfer plate for use in, for example, a heat exchanger and a heating or cooling machine.
接觸或接近欲進行熱交換、加熱或冷卻的對象物而配置的傳熱板係由使例如高溫液或冷卻水等的熱媒體循環的熱媒體用管貫穿做為本體的基底構件而形成。The heat transfer plate disposed in contact with or close to the object to be heat-exchanged, heated, or cooled is formed by a heat medium tube that circulates a heat medium such as a high-temperature liquid or cooling water as a base member of the body.
該傳熱板的製造方法為例如專利文獻1所記載的方法。第28圖為專利文獻1的傳熱板的圖，第28a圖為立體圖，第28b圖為剖視圖。專利文獻1的傳熱板100包括具有開口於表面的斷面呈矩形的蓋槽106及開口於蓋槽106底面的凹槽108的基底構件102、插入凹槽108的熱媒體用管116以及嵌合於蓋槽116的蓋板110。沿著蓋槽106的側壁105與蓋板110的側面113以及側壁105與蓋板110的側面114的平接部實施摩擦攪拌接合而形成。在蓋槽106與蓋板110的平接部上形成塑性化區域W0 。The method for producing the heat transfer plate is, for example, the method described in Patent Document 1. Fig. 28 is a view showing a heat transfer plate of Patent Document 1, and Fig. 28a is a perspective view, and Fig. 28b is a cross-sectional view. The heat transfer plate 100 of Patent Document 1 includes a base member 102 having a rectangular cover groove 106 opened to the surface and a groove 108 opening to the bottom surface of the cover groove 106, a heat medium tube 116 inserted into the groove 108, and the embedded body. Cover plate 110 of cover groove 116. The side wall 105 of the cover groove 106 is formed by friction stir welding with the side surface 113 of the cover 110 and the flat portion of the side wall 105 and the side surface 114 of the cover plate 110. A plasticized region W 0 is formed on the flat portion of the cover groove 106 and the cover plate 110.
[專利文獻]特開2004-314115號公報[Patent Document] JP-A-2004-314115
如第28b圖所示，在傳熱板100上，由凹槽108、熱媒體用管116的外周面以及蓋板110的背面形成空隙部120，當傳熱板100的內部存在空隙部120時，從熱媒體用管116發出的熱傳遞至蓋板110，因此會有傳熱板100的熱交換率下降的問題。因此，凹槽108的深度及寬度最好形成與熱媒體用管116的外徑相同，使空隙部120變小。As shown in Fig. 28b, on the heat transfer plate 100, a void portion 120 is formed by the groove 108, the outer peripheral surface of the heat medium tube 116, and the back surface of the cap plate 110, and when the gap portion 120 exists inside the heat transfer plate 100, Since the heat generated from the heat medium tube 116 is transmitted to the cap plate 110, there is a problem that the heat exchange rate of the heat transfer plate 100 is lowered. Therefore, the depth and width of the groove 108 are preferably formed to be the same as the outer diameter of the heat medium tube 116, so that the gap portion 120 becomes small.
例如，使熱媒體用管116的至少一部分彎曲而埋入基底構件102時，將熱媒體用管116插入凹槽108而將蓋板110配置於蓋槽106上是有困難的，因此必須確保凹槽108的深度及寬度比熱媒體用管116的外徑大。即，使熱媒體用管116的至少一部分彎曲而埋入基底構件102時，無法使凹槽108的深度及寬度比熱媒體用管116的外徑大，藉 此空隙部120會變得更大。藉此，傳熱板100的熱交換效率會有降低的問題。For example, when at least a part of the heat medium tube 116 is bent and buried in the base member 102, it is difficult to insert the heat medium tube 116 into the groove 108 and arrange the cover 110 on the cover groove 106. Therefore, it is necessary to ensure the concave portion. The depth and width of the groove 108 are larger than the outer diameter of the heat medium tube 116. In other words, when at least a part of the heat medium tube 116 is bent and embedded in the base member 102, the depth and width of the groove 108 cannot be made larger than the outer diameter of the heat medium tube 116. This void portion 120 will become larger. Thereby, the heat exchange efficiency of the heat transfer plate 100 may be lowered.
從此觀點而言，本發明提供一種傳熱板的製造方法，使傳熱板的熱交換效率變高且容易製造。From this point of view, the present invention provides a method for producing a heat transfer plate which has high heat exchange efficiency and is easy to manufacture.

At least one of the width and the height of the space portion is set to be larger than the outer diameter of the heat medium tube in the gap portion around the heat medium tube.
根據上述製造方法，上述第一金屬構件與上述第二金屬構件所形成的空間部的寬度及高度的至少其中之一由於比上述熱媒體用管的外徑大，即使熱媒體用管的一部份彎曲，也容易地進行準備工程。又，藉由流入攪拌工程，使塑性流動材流入形成於熱媒體用管周圍的空隙部而掩埋該空隙部，因此熱可有效地在熱媒體用管及其周圍的第一金屬構件及第二金屬構件之間傳遞。例如，將冷卻水通入熱媒體用管而有效地冷卻傳熱板及冷卻對象物。According to the above manufacturing method, at least one of the width and the height of the space portion formed by the first metal member and the second metal member is larger than the outer diameter of the heat medium tube, even if it is a part of the heat medium tube The bending is also easy to prepare for the project.

又，在本發明中，最好使用比上述流入攪拌用旋轉工具還小型的旋轉工具進行上述接合工程。根據上述製造方法，在流入攪拌工程中使塑性流動化至深的部分之同時，由於在接合工程中的摩擦攪拌接合的塑性化區域變小，因此容易進行接合作業。Further, in the present invention, it is preferable to perform the above-described joining process using a rotary tool which is smaller than the above-described inflow stirring rotary tool. According to the above-described manufacturing method, the plasticized fluidization is deepened in the inflow stirring process, and the plasticized region of the friction stir welding in the joining process is small, so that the joining work can be easily performed.

The lower opening is formed into a rectangular cross section. The second recess 6 has a top surface 6c and upright surfaces 6a, 6b that are vertically erected from the top surface 6c.
而且，第一金屬構件2及第二金屬構件3雖然在本實施形態中為鋁合金，但是只要是可摩擦攪拌的金屬材料，其他的材料亦可。Further, although the first metal member 2 and the second metal member 3 are aluminum alloys in the present embodiment, other materials may be used as long as they are friction stirable metal materials.
熱媒體用管4，如第2圖及第3圖所示，其為平面觀看呈U字形的圓筒管。熱媒體用管4的材質並無特別限制，在本實施形態中為銅製。熱媒體用管4在中空部4a中使例如高溫液、高溫氣體等的熱媒體做熱循環，其為使熱傳遞至第一金屬構件2及第二金屬構件3的構件，或者是使例如冷卻水、冷卻氣體等的熱媒體在中空部4a中循環而將熱從第一金屬構件2及第二金屬構件3傳遞出的構件。而且，在熱媒體用管4的中空部4a通過例如加熱器，而做為將加熱器所產生的熱傳遞至第一金屬構件2及第二金屬構件3的構件而利用。The heat medium tube 4, as shown in Figs. 2 and 3, is a U-shaped cylindrical tube viewed in plan. The material of the heat medium tube 4 is not particularly limited, and is made of copper in the present embodiment. The heat medium tube 4 thermally circulates a heat medium such as a high temperature liquid or a high temperature gas in the hollow portion 4a, which is a member for transferring heat to the first metal member 2 and the second metal member 3, or is cooled, for example. A heat medium such as water or a cooling gas circulates in the hollow portion 4a to transfer heat from the first metal member 2 and the second metal member 3. Further, the hollow portion 4a of the heat medium tube 4 is used as a member for transferring heat generated by the heater to the first metal member 2 and the second metal member 3 by, for example, a heater.
如第3b圖所示，當第二金屬構件3配置於第一金屬構件2時，第一金屬構件2的第一凹槽5與第二金屬構件3的第二凹槽6重合，形成剖面呈矩形的空間部K。熱媒體用管4被容納於空間部K。As shown in FIG. 3b, when the second metal member 3 is disposed on the first metal member 2, the first groove 5 of the first metal member 2 and the second groove 6 of the second metal member 3 overlap to form a cross section. The space portion K of the rectangle. The heat medium tube 4 is housed in the space portion K.
於此，第一凹槽5的深度係形成熱媒體用管4的外徑的1/2。又，第一凹槽5的寬度形成熱媒體用管4的外徑的1.1倍。另一方面，第二凹槽6的深度形成熱媒體用管4的半徑的1.1倍。又，第二凹槽6的寬度形成熱媒體用管4的外徑的1.1倍。因此，當熱媒體用管4及第二金屬構件3配置於第一金屬構件2時，第一凹槽5與熱媒體用管4的下端接觸，熱媒體用管4的左右端及上端與第一凹槽5及第二凹槽6以微細的間隙分離。換言之，空間部K的寬度及高度形成比熱媒體用管4的外徑大。Here, the depth of the first groove 5 is 1/2 of the outer diameter of the heat medium tube 4. Further, the width of the first groove 5 forms 1.1 times the outer diameter of the heat medium tube 4. On the other hand, the depth of the second groove 6 forms 1.1 times the radius of the heat medium tube 4. Further, the width of the second groove 6 forms 1.1 times the outer diameter of the heat medium tube 4. Therefore, when the heat medium tube 4 and the second metal member 3 are disposed on the first metal member 2, the first groove 5 is in contact with the lower end of the heat medium tube 4, and the left and right ends and the upper end of the heat medium tube 4 are A groove 5 and a second groove 6 are separated by a fine gap. In other words, the width and height of the space portion K are formed larger than the outer diameter of the heat medium tube 4.
在矩形斷面的空間部K內，由於插入圓形斷面的熱媒體用管4，在熱媒體用管4的周圍形成空隙部。例如，如第2圖所示，在熱媒體用管4內流動的媒體的流動方向成為「Y」，在熱媒體用管4的周圍所形成的空隙部中，相對於流動方向Y形成於左上側的部分成為「第一空隙部P1」，形成於右上側的部分成為「第二空隙部P2」，形成於左下側的部分成為「第三空隙部P3」，形成於右下側的部分成為「第四空隙部P4」。又，第一金屬構件2、第二金屬構件3以及熱媒體用管4的構件成為「暫時組合構造體U」。In the space portion K of the rectangular cross section, a cavity portion is formed around the heat medium tube 4 by inserting the heat medium tube 4 having a circular cross section. For example, as shown in Fig. 2, the flow direction of the medium flowing through the heat medium tube 4 is "Y", and the gap portion formed around the heat medium tube 4 is formed on the upper left side with respect to the flow direction Y. The portion on the side is the "first gap portion P1", the portion formed on the upper right side is the "second gap portion P2", the portion formed on the lower left side is the "third gap portion P3", and the portion formed on the lower right side becomes "fourth gap portion P4". Moreover, the members of the first metal member 2, the second metal member 3, and the heat medium tube 4 are "temporary combined structures U".
又，如第3b圖所示，第一金屬構件2與第二金屬構件3平接而形成平接部V。在平接部V中，出現於暫時組合構造體U的一邊的側面的部分成為「平接部V1」，出現於另一邊側面的部分成為「平接部V2」。Further, as shown in FIG. 3b, the first metal member 2 and the second metal member 3 are in contact with each other to form the flat portion V. In the flat portion V, the portion that appears on the side surface of one side of the temporary composite structure U becomes the "flat portion V1", and the portion that appears on the other side surface becomes the "flat portion V2".

A fluidized and integrated area. In other words, when the friction stir welding is performed along the joint portions V1 and V2 by using the joining rotary tool 50 (see FIG. 5) to be described later, the first metal member 2 and the second portion in the flat portions V1 and V2 are used. The metal material of the metal member 3 is integrated by the frictional thermoplastic fluidization of the joining rotary tool 50, and the first metal member 2 and the second metal member 3 are joined.
如第1圖及第4圖所示，塑性化區域W3、W4由從第二金屬構件3表面3a插入的流入攪拌用旋轉工具55(參照第5圖)沿著第二凹槽6移動之際而形成。塑性化區域W3的一部份流入形成於熱媒體用管4的周圍的第一空隙部P1。塑性化區域W4的一部份係流入形成於熱媒體用管4的周圍的第二空隙部P2。即，塑性化區域W3、W4為第二金屬構件3的一部份塑性流動而分別流入第一空隙部P1及第二空隙部P2的區域，與熱媒體用管4接觸。As shown in FIG. 1 and FIG. 4, the plasticized regions W3 and W4 are moved along the second groove 6 by the inflowing stirring rotary tool 55 (see FIG. 5) inserted from the front surface 3a of the second metal member 3. And formed. A part of the plasticized region W3 flows into the first gap portion P1 formed around the heat medium tube 4. A part of the plasticized region W4 flows into the second void portion P2 formed around the heat medium tube 4.

塑性化區域W5、W6為從第一金屬構件2的背面2b插入的流入攪拌用旋轉工具55沿著第一凹槽5移動之際形成。塑性化區域W5的一部份係流入形成於熱媒體用管4的周圍的第三空隙部P3。塑性化區域W6的一部份係流入形成於熱媒體用管4的周圍的第四空隙部P4。即，塑性化區域W5、W6為第二金屬構件3的一部份塑性流動而分別流入第三空隙部P3及第四空隙部P4的區域，與熱媒體用管4接觸。The plasticized regions W5 and W6 are formed when the inflow stirring rotary tool 55 inserted from the back surface 2b of the first metal member 2 moves along the first recess 5. A part of the plasticized region W5 flows into the third void portion P3 formed around the heat medium tube 4. A part of the plasticized region W6 flows into the fourth gap portion P4 formed around the heat medium tube 4.

The pin 53 has a tapered shape which is tapered toward the front end. Further, on the circumferential surface of the pin 53, a plurality of small grooves (not shown) along the axial direction and spiral grooves along the radial direction are formed.
摩擦攪拌接合是在由未圖示的治具限制第一金屬構件2與第二金屬構件3的狀態下，將高速旋轉的接合用旋轉工具50壓入平接部V1，使其沿著平接部V1移動。藉由高速旋轉的銷53，其周圍的第一金屬構件2及第二金屬構件3的鋁合金材料由摩擦熱加熱而塑性流動化後冷卻而一體化。在對平接部V1進行摩擦攪拌接合之後，也對平接部V2同樣地進行摩擦攪拌接合。In the friction stir welding, in a state in which the first metal member 2 and the second metal member 3 are restricted by a jig (not shown), the joining rotary tool 50 that rotates at a high speed is pressed into the flat portion V1 so as to be flattened. Part V1 moves. The aluminum alloy material of the first metal member 2 and the second metal member 3 around the high-speed rotating pin 53 is heated by frictional heat, plastically fluidized, and then cooled and integrated. After the friction stir welding of the flat portion V1, the friction stir welding is also performed similarly to the flat portion V2.
在流入攪拌工程，如第5d、6a至6c圖所示，流入攪拌用旋轉工具55從熱媒體用管4及第二金屬構件3所構成的暫時組合構造體U的表面及背面移動而使塑性流動材Q流入第一空隙部P1~第四空隙部P4。本實施形態的流入攪拌工程包括使流入攪拌用旋轉工具55在第二金屬構件3的表面3a移動而使塑性流動材Q流入第一空隙部P1及第二空隙部P2的表面側流入攪拌工程以及使流入攪拌用旋轉工具55在第一金屬構件2的背面2b移動而使塑性流動材Q流入第三空隙部P3及第四空隙部P4的背面側流入攪拌工程。In the inflow stirring process, as shown in Figs. 5d, 6a to 6c, the inflow stirring rotary tool 55 moves from the surface and the back surface of the temporary combined structure U composed of the heat medium tube 4 and the second metal member 3 to plasticize. The fluid material Q flows into the first to third gap portions P1 to P4. The inflow and agitation process of the present embodiment includes moving the inflow stirring rotary tool 55 to the surface 3a of the second metal member 3, and flowing the plastic fluid material Q into the surface side of the first gap portion P1 and the second gap portion P2 to flow into the stirring process and The inflow stirring rotary tool 55 is moved on the back surface 2b of the first metal member 2, and the plastic flow material Q flows into the back surface side of the third gap portion P3 and the fourth gap portion P4 to flow into the stirring process.
而且，在表面側流入攪拌工程中，使塑性流動材Q流入第一空隙部P1的工程為第一表面側流入攪拌工程，使塑性流動材Q流入第二空隙部P2的工程為第二表面側流入攪拌工程。又，使塑性流動材Q流入第三空隙部P3的工程為第一背面側流入攪拌工程，使塑性流動材Q流入第四空隙部P4的工程為第二背面側流入攪拌工程。Further, in the surface side inflow stirring process, the process of flowing the plastic flowing material Q into the first gap portion P1 is the first surface side flowing into the stirring process, and the process of flowing the plastic flowing material Q into the second gap portion P2 is the second surface side. Flow into the mixing project. Further, the process of flowing the plastic fluid material Q into the third gap portion P3 is a first back side flow inflow stirring process, and the process of flowing the plastic fluid material Q into the fourth space portion P4 is a second back side flow inflow stirring process.
在第一表面側流入攪拌工程中，如第5d圖所示，相對於熱媒體用管4的流動方向Y(參照第2圖)，使藉由摩擦攪拌而塑性流動化的塑性流動材Q流入形成於左上側的第一空隙部P1。流入攪拌用旋轉工具55以例如工具鋼形成，具有與接合用旋轉工具50相同的形狀，圓柱形的工具本體56、從工具本體56的底面57的中心部分以同心軸的方式垂下的銷58。流入攪拌用旋轉工具55係使用比接合用旋轉工具50還大形的工具。In the first surface side inflow stirring process, as shown in Fig. 5d, the plastic flow material Q which is plastically fluidized by friction stir is flown in the flow direction Y of the heat medium tube 4 (see Fig. 2). The first gap portion P1 is formed on the upper left side. The inflow agitation rotary tool 55 is formed of, for example, tool steel, and has the same shape as the engagement rotary tool 50. The cylindrical tool body 56 has a pin 58 that is concentrically suspended from a central portion of the bottom surface 57 of the tool body 56. The inflow stirring tool 55 is a tool that is larger than the joining rotary tool 50.
在第一表面側流入攪拌工程中，在第二金屬構件3的表面3a上，壓入高速旋轉的流入攪拌用旋轉工具55，沿著下方的第二凹槽6以平面觀看呈U字形的軌跡移動流入攪拌用旋轉工具55。流入攪拌用旋轉工具55移動而使工具本體56的底面57(肩部)的投影部分的一部份與第一空隙部P1重合。此時，藉由高速旋轉的銷58，其周圍的第二金屬構件3的鋁合金材料藉由摩擦熱加熱而塑性流動化。由於流入攪拌用旋轉工具55以既定深度壓入，因此塑性流動化的塑性流動材Q流入第一空隙部P1並與熱媒體用管4接觸。In the first surface side inflow stirring process, on the surface 3a of the second metal member 3, a high-speed rotating inflow agitation rotating tool 55 is pressed, and a U-shaped trajectory is viewed in a plane along the lower second groove 6. The moving inflow stirring tool 55 is moved. The inflow stirring rotary tool 55 is moved so that a part of the projected portion of the bottom surface 57 (shoulder portion) of the tool body 56 overlaps with the first gap portion P1. At this time, the aluminum alloy material of the second metal member 3 around it is plastically fluidized by frictional heat heating by the pin 58 rotated at a high speed. Since the inflowing stirring rotary tool 55 is press-fitted at a predetermined depth, the plastic fluidized plastic material Q flows into the first gap portion P1 and comes into contact with the heat medium tube 4.
於此，如第3b圖所示，雖然熱媒體用管4的左右端及上端係與第一凹槽5及第二凹槽6以微細間隙配置，當塑性流動材Q流入第一空隙部P1時，塑性流動材Q的熱由於被熱媒體用管4吸收而使流動性降低。因此，流入第一空隙部P1的塑性流動材Q不會流入第二空隙部P2及第三空隙部P3而滯留在第一空隙部P1充填而硬化。Here, as shown in FIG. 3b, the left and right ends and the upper end of the heat medium tube 4 are arranged with a fine gap between the first groove 5 and the second groove 6, and the plastic flow material Q flows into the first gap portion P1. At the time, the heat of the plastic fluid material Q is absorbed by the heat medium tube 4, and the fluidity is lowered. Therefore, the plastic fluid material Q flowing into the first void portion P1 does not flow into the second void portion P2 and the third void portion P3, but stays in the first void portion P1 to be filled and hardened.
在第二表面側流入攪拌工程中，如第6a圖所示，相對於熱媒體用管4的流動方向Y(參照第2圖)，使由摩擦攪拌而塑性流動化的塑性流動材Q流入第二空隙部P2。第二表面側流入攪拌工程除了是在第二空隙部P2進行之外，其餘與第一表面側流入攪拌工程相同，因此省略其說明。而且，在表面側流入攪拌工程結束之後，切削除去形成於第二金屬構件3的表面3a的毛邊，而使表面3a變得平滑。When the second surface side flows into the agitation process, as shown in Fig. 6a, the plastic flow material Q which is plastically fluidized by friction stir is flown into the flow direction Y (see Fig. 2) of the heat medium tube 4 Two void portions P2. The second surface side inflow agitation process is the same as the first surface side inflow stirring process except for the second gap portion P2, and therefore the description thereof will be omitted. Further, after the surface side inflow and agitation process is completed, the burrs formed on the surface 3a of the second metal member 3 are removed by cutting, and the surface 3a is smoothed.
在背面側流入攪拌工程中，如第6b及6c圖所示，在暫時組合構造體U的表面及背面反轉之後，在第一金屬構件2的背面2b使流入攪拌用旋轉工具5沿著第一凹槽5移動而將由摩擦熱而塑性流動化的塑性流動材Q流入第三空隙部P3及第四空隙部P4。在第一背面側流入攪拌工程中，如第6b圖所示，藉由摩擦攪拌而使塑性流動化的塑性流動材Q流入第三空隙部P3。在第一背面側流入攪拌工程中，在第一金屬構件2的背面2b壓入高速旋轉的流入攪拌用旋轉工具55，沿著第一凹槽5使流入攪拌用旋轉工具55以平面觀看呈U字形的軌跡移動。流入攪拌用旋轉工具55移動使工具本體56的底面57(肩部)的投影部分的一部份與熱媒體用管4的第三空隙部P3重疊。此時，藉由高速旋轉的銷58，其周圍的第一金屬構件2的鋁合金材料由於摩擦熱加熱而塑性流動化。流入攪拌用旋轉工具55由於壓入既定深度，塑性流動化的塑性流動材Q流入第三空隙部P3，並與熱媒體用管4接觸。In the agitation process in the back side, as shown in FIGS. 6b and 6c, after the surface and the back surface of the temporary composite structure U are reversed, the inflowing rotary tool 5 is caused to flow along the back surface 2b of the first metal member 2 When a groove 5 moves, the plastic flow material Q which is plastically fluidized by frictional heat flows into the third gap portion P3 and the fourth gap portion P4. In the first back side flowing into the stirring process, as shown in Fig. 6b, the plastic fluidized material Q which is plastically fluidized flows into the third gap portion P3 by friction stir. In the first back side flow inflow stirring process, the inflow stirring rotary tool 55 that is rotated at a high speed is pressed into the back surface 2b of the first metal member 2, and the inflow stirring rotary tool 55 is viewed in a plane along the first groove 5. The trajectory of the glyph moves. The inflow stirring tool 55 moves so that a part of the projected portion of the bottom surface 57 (shoulder portion) of the tool body 56 overlaps with the third gap portion P3 of the heat medium tube 4. At this time, the aluminum alloy material of the first metal member 2 around it is plastically fluidized by frictional heat heating by the pin 58 rotated at a high speed. When the inflow stirring tool 55 is pressed in a predetermined depth, the plastic fluid material Q which is plastically fluidized flows into the third gap portion P3 and comes into contact with the heat medium tube 4.
在第二背面側流入攪拌工程中，如第6c圖所示，由摩擦攪拌而塑性流動化的塑性流動材Q流入第四空隙部P4。第二背面側流入攪拌工程除了是在第四空隙部P4進行之外，其餘與第一背面側流入攪拌工程相同，因此省略其說明。而且，在背面側流入攪拌工程結束之後，最好切削除去形成於第一金屬構件2的背面2a的毛邊，而使背面2a變得平滑。In the second back side flowing into the stirring process, as shown in Fig. 6c, the plastic fluid material Q which is plastically fluidized by friction stirring flows into the fourth gap portion P4. The second back side inflow stirring process is the same as the first back side inflow stirring process except for the fourth gap portion P4, and therefore the description thereof will be omitted. Further, after the completion of the inflow and the stirring process on the back side, it is preferable to cut off the burrs formed on the back surface 2a of the first metal member 2 to smooth the back surface 2a.
而且，在表面側流入攪拌工程及背面側流入攪拌工程中，根據第一空隙部P1~第四空隙部P4的形狀及大小，設定流入攪拌用旋轉工具55的壓入量及插入位置等。熱媒體用管4不會崩潰的程度，使流入攪拌用旋轉工具55接近而使塑性流動材Q無間隙地流入第一空隙部P1~第四空隙部P4。In addition, in the surface side inflow stirring process and the back side inflow stirring process, the pressing amount, the insertion position, and the like of the inflow stirring rotary tool 55 are set in accordance with the shape and size of the first to fourth gap portions P1 to P4. To the extent that the heat medium tube 4 does not collapse, the inflow stirring tool 55 approaches, and the plastic fluid material Q flows into the first gap portion P1 to the fourth gap portion P4 without a gap.
例如，如第7圖所示，流入攪拌用旋轉工具55的銷58的前端最好插入得比第二凹槽6的頂面6c(背面側流入攪拌工程時為第一凹槽5的底面5c)還深。又，流入攪拌用旋轉工具55的銷58的前端與連接於熱媒體用管4的假想鉛直面的最接近距離最好是1~3mm。藉此，在使熱媒體用管4不崩壞的程度上使塑性流動材Q流入第一空隙部P1。當最接近距離L小於1mm時，流入攪拌用旋轉工具55接近熱媒體用管4，熱媒體用管4有崩壞的可能性。又，當最接近距離L大於3mm時，塑性流動材Q可能不流入第一空隙部P1。For example, as shown in Fig. 7, the front end of the pin 58 that flows into the stirring rotary tool 55 is preferably inserted more than the top surface 6c of the second recess 6 (the bottom surface 5c of the first recess 5 when the back side flows into the stirring process) ) Still deep. Further, the closest distance between the tip end of the pin 58 that flows into the stirring rotary tool 55 and the virtual vertical surface connected to the heat medium tube 4 is preferably 1 to 3 mm. Thereby, the plastic fluid material Q flows into the first gap portion P1 to such an extent that the heat medium tube 4 does not collapse. When the closest distance L is less than 1 mm, the inflow stirring rotary tool 55 approaches the heat medium tube 4, and the heat medium tube 4 may collapse. Also, when the closest distance L is larger than 3 mm, the plastic flowing material Q may not flow into the first gap portion P1.
又，流入攪拌用旋轉工具55的壓入量(壓入長度)，例如在第一表面側流入攪拌工程中，工具本體56壓退的第二金屬構件3(或第一金屬構件2)的金屬的體積相等於填充於第一空隙部P1的塑性流動化的鋁合金材料的體積以及塑性化區域W3的寬度方向兩側產生的毛邊的體積的和。Further, the amount of press-fitting (press-in length) of the agitation rotary tool 55 flows into the metal of the second metal member 3 (or the first metal member 2) that is retracted by the tool body 56, for example, when the first surface side flows into the agitation process. The volume is equal to the sum of the volume of the plastic fluidized aluminum alloy material filled in the first void portion P1 and the volume of the burrs generated on both sides in the width direction of the plasticized region W3.
根據以上說明的傳熱板的製造方法，由形成於第一金屬構件2的表面2a的第一凹槽5與形成於第二金屬構件3的背面3b的第二凹槽6所構成的空間部K中，由於空間部K的寬度及高度形成比熱媒體用管4的外徑大，即使在熱媒體用管4的一部份彎曲的情況下，也容易地進行上述插入工程及配置工程。According to the above-described method of manufacturing a heat transfer plate, the space formed by the first groove 5 formed on the surface 2a of the first metal member 2 and the second groove 6 formed on the back surface 3b of the second metal member 3 In K, the width and height of the space portion K are formed larger than the outer diameter of the heat medium tube 4, and the insertion work and the arrangement work can be easily performed even when a part of the heat medium tube 4 is bent.
又，藉由表面側流入攪拌工程及背面側流入攪拌工程，藉由使塑性流動材Q流入形成於熱媒體用管4的周圍的第一空隙部P1~第四空隙部P4，由於可掩埋該空隙部，可提高傳熱板1的熱交換效率。In addition, the first flow portion P1 to the fourth gap portion P4 formed around the heat medium tube 4 can be buried by the surface-side inflow stirring process and the back side inflow stirring process. The void portion can improve the heat exchange efficiency of the heat transfer plate 1.
又，根據本實施形態，在表面側流入攪拌工程之前，使用比較小的接合用旋轉工具50而接合第一金屬構件2與第二金屬構件3，因此在表面側流入攪拌工程中，在確實地固定第一金屬構件2與第二金屬構件3的狀態下可進行摩擦攪拌。因此，使用比較大的流入攪拌用旋轉工具55而以大的壓入力作用的摩擦攪拌接合可在穩定的狀態下進行。Further, according to the present embodiment, the first metal member 2 and the second metal member 3 are joined by using the relatively small joining rotary tool 50 before the surface side flows into the stirring process, so that the surface side flows into the stirring process, and it is surely Friction stirring can be performed in a state in which the first metal member 2 and the second metal member 3 are fixed. Therefore, the friction stir welding using a relatively large inflow stirring rotary tool 55 with a large press-in force can be performed in a stable state.
而且，在本實施形態中，雖然在接合工程後進行表面側流入攪拌工程，也可以在表面側流入攪拌工程之後進行接合工程。此時，將第一金屬構件2與第二金屬構件3在寬度方向及長度方向以未圖示的治具固定，可在穩定的狀態下進行表面側流入攪拌工程中的摩擦攪拌。Further, in the present embodiment, the surface side inflow stirring process is performed after the joining process, and the joining process may be performed after the surface side flows into the stirring process. At this time, the first metal member 2 and the second metal member 3 are fixed by a jig (not shown) in the width direction and the longitudinal direction, and the friction stir in the surface side inflow stirring process can be performed in a stable state.
又，在本實施形態中，在接合工程中，雖然橫越平接部V1、V2的全長而實施摩擦攪拌接合，但並不限定於此，沿著平接部V1、V2相隔既定間隔而斷續地實施摩擦攪拌接合亦可。根據如此的傳熱板的製造方法，可減低接合工程所需的手續與時間。Further, in the present embodiment, the friction stir welding is performed across the entire length of the flat portions V1 and V2 in the joining process, but the present invention is not limited thereto, and the flat portions V1 and V2 are separated by a predetermined interval. It is also possible to carry out friction stir welding continuously. According to such a method of manufacturing a heat transfer plate, the procedures and time required for the joining process can be reduced.
又，在本實施形態中，雖然空間部K的寬度及高度都比熱媒體用管4的外徑大，但寬度及高度其中之一較大亦可。又，熱媒體用管4的斷面形狀雖然在本實施形態中為圓形，但其他形狀亦可。又，雖然熱媒體用管4的平面形狀在本實施形態中為U字形，但例如直線形狀、蛇行形狀或圓形亦可。又，雖然表示第一凹槽5及第二凹槽6的寬度及深度尺寸，但並非用於限定本發明。例如，在熱媒體用管4的平面形狀複雜的情況下，隨此，也可以將第一凹槽5及第二凹槽6的寬度及深度適當地變大。又，在本實施形態中，雖然將熱媒體用管4及第二金屬構件3配置於第一金屬構件2，但並不限定於此。例如，將熱媒體用管4插入第二金屬構件3的第二凹槽6之後，由也可以配置成第二金屬構件3的上方覆蓋第一金屬構件。又，在本實施形態中，可省略接合工程。即，在流入攪拌工程中，第一金屬構件2及第二金屬構件3可一體化。Further, in the present embodiment, the width and height of the space portion K are larger than the outer diameter of the heat medium tube 4, but one of the width and the height may be large. Further, although the cross-sectional shape of the heat medium tube 4 is circular in the present embodiment, other shapes may be used. Further, although the planar shape of the heat medium tube 4 is U-shaped in the present embodiment, it may be, for example, a linear shape, a meander shape, or a circular shape. Further, although the width and depth dimensions of the first groove 5 and the second groove 6 are shown, they are not intended to limit the present invention. For example, when the planar shape of the heat medium tube 4 is complicated, the width and depth of the first groove 5 and the second groove 6 may be appropriately increased as described above. Further, in the present embodiment, the heat medium tube 4 and the second metal member 3 are disposed in the first metal member 2, but the invention is not limited thereto. For example, after the heat medium tube 4 is inserted into the second recess 6 of the second metal member 3, the first metal member may be covered by the upper portion of the second metal member 3. Further, in the present embodiment, the joining process can be omitted. That is, in the inflow and agitation process, the first metal member 2 and the second metal member 3 can be integrated.
接著，針對本發明的第二實施形態做說明。第二實施形態的傳熱板的製造方法中，就不進行背面側流入攪拌工程的特徵而言，是與第一實施形態不同的。而且，雖然未具體圖示，熱媒體用管4與第一實施形態相同呈平面U字形。Next, a second embodiment of the present invention will be described. In the method for producing a heat transfer plate according to the second embodiment, the feature of not performing the back side inflow stirring process is different from that of the first embodiment. Further, although not specifically illustrated, the heat medium tube 4 has a flat U-shape as in the first embodiment.
第二實施形態的傳熱板的製造方法，如第8圖及第9圖所示，其包括在形成第一金屬構件12及第二金屬構件13之同時，將熱媒體管4及及第二金屬構件13配置於第一金屬構件12的準備工程、使接合用旋轉工具50沿著平接部V1、V2移動而進行摩擦攪拌接合的接合工程以及從第二金屬構件13的表面13a側使流入攪拌用旋轉工具55移動而使塑性流動材Q流入第一空隙部P1及第二空隙部P2的表面側流入攪拌工程。The method for manufacturing the heat transfer plate according to the second embodiment includes the heat medium tube 4 and the second portion while forming the first metal member 12 and the second metal member 13 as shown in FIGS. 8 and 9. The metal member 13 is disposed in a preparation process of the first metal member 12, a joining process in which the joining rotary tool 50 is moved along the flat portions V1 and V2 to perform friction stir welding, and an inflow from the surface 13a side of the second metal member 13 The stirring rotary tool 55 moves to cause the plastic flow material Q to flow into the surface of the first gap portion P1 and the second gap portion P2 to flow into the stirring process.
準備工程包括形成第一金屬構件12與第二金屬構件13的切削工程、將熱媒體用管4插入形成於第一金屬構件12的第一溝槽15中的插入工程以及將第二金屬構件3配置於第一金屬構件12的配置工程。The preparation process includes cutting work for forming the first metal member 12 and the second metal member 13, inserting the heat medium tube 4 into the first groove 15 formed in the first metal member 12, and inserting the second metal member 3 The configuration work of the first metal member 12 is disposed.
在切削工程中，如第8a圖所示，藉由公知的切削加工，在厚板構件上切出斷面觀看呈U字形的第一凹槽15而形成第一金屬構件12。第一凹槽15的底部15a係切成圓弧狀，形成與熱媒體用管4的外周面相同的曲率。第一凹槽5的深度形成比熱媒體用管4的外徑小，第一凹槽5的寬度形成大略與熱媒體用管4的外徑相等。In the cutting process, as shown in Fig. 8a, the first metal member 12 is formed by cutting a first groove 15 having a U-shaped cross section on a thick plate member by a known cutting process. The bottom portion 15a of the first groove 15 is cut into an arc shape to have the same curvature as the outer peripheral surface of the heat medium tube 4. The depth of the first groove 5 is formed smaller than the outer diameter of the heat medium tube 4, and the width of the first groove 5 is formed to be substantially equal to the outer diameter of the heat medium tube 4.
接著，藉由公知的切削加工，在厚板構件上切出剖面呈矩形的第二凹槽16而形成第二金屬構件13。第二凹槽16的寬度形成大略與熱媒體用管4的外徑相等。又，第二凹槽16的深度，如第8b圖所示，在熱媒體管4及及第二金屬構件13配置於第一金屬構件12之同時，第二凹槽16的頂面16c與熱媒體用管4分隔微細的間隙。Next, the second metal member 13 is formed by cutting a second recess 16 having a rectangular cross section on the thick plate member by a known cutting process. The width of the second groove 16 is formed to be substantially equal to the outer diameter of the heat medium tube 4. Moreover, as shown in FIG. 8b, the top surface 16c of the second groove 16 and the heat of the second groove 16 are disposed while the heat medium tube 4 and the second metal member 13 are disposed on the first metal member 12, as shown in FIG. 8b. The medium is separated by a tube 4 with a fine gap.
在插入工程中，如第8b圖所示，熱媒體用管4插入第一凹槽15。此時，熱媒體用管4的下半部與第一凹槽15的底面15c接觸。而且，當熱媒體用管4插入第一凹槽15時，熱媒體用管4的上端位於比第一金屬構件12的表面12a還上方的位置。In the insertion process, as shown in Fig. 8b, the heat medium tube 4 is inserted into the first groove 15. At this time, the lower half of the heat medium tube 4 is in contact with the bottom surface 15c of the first groove 15. Further, when the heat medium tube 4 is inserted into the first recess 15, the upper end of the heat medium tube 4 is located above the surface 12a of the first metal member 12.
在配置工程中，如第8b圖所示，將熱媒體用管4的上部插入形成於第二金屬構件13的第二凹槽16，同時將第二金屬構件13配置於第一金屬構件12上。此時，熱媒體用管4與形成於第二金屬構件13的第二凹槽16的兩直立面16a、16b及頂面16c分隔微小的間隙。即，第一凹槽15與第二凹槽16所形成的空間部K1的寬度係形成與熱媒體用管4的外徑大略相同，空間部K1的高度H形成比熱媒體用管4的外徑大。In the configuration process, as shown in FIG. 8b, the upper portion of the heat medium tube 4 is inserted into the second recess 16 formed in the second metal member 13, while the second metal member 13 is disposed on the first metal member 12. . At this time, the heat medium tube 4 is separated from the two upright surfaces 16a, 16b and the top surface 16c of the second recess 16 formed in the second metal member 13 by a slight gap. That is, the width of the space portion K1 formed by the first groove 15 and the second groove 16 is formed to be substantially the same as the outer diameter of the heat medium tube 4, and the height H of the space portion K1 is formed to be larger than the outer diameter of the heat medium tube 4. Big.
於此，在空間部K1中，形成於熱媒體用管4的周圍的空隙部中，相對於流動方向Y(參照第2圖)，以形成於左上側的部分為第一空隙部P1，形成於右上的部分為第二空隙部P2。In the space portion K1, in the gap portion formed around the heat medium tube 4, the portion formed on the upper left side is the first gap portion P1 with respect to the flow direction Y (see FIG. 2). The upper right portion is the second gap portion P2.
接著，如第9a圖所示，使接合用旋轉工具50沿著平接第一金屬構件12與第二金屬構件13的平接部V1、V2(參照第8b圖)進行摩擦攪拌接合。藉此，可接合第一金屬構件12與第二金屬構件13。Next, as shown in Fig. 9a, the joining rotary tool 50 is friction stir welded to the flat portions V1 and V2 (see Fig. 8b) which are in contact with the first metal member 12 and the second metal member 13 . Thereby, the first metal member 12 and the second metal member 13 can be joined.
在表面側流入攪拌工程中，如第9b圖及第9c圖所示，從第二金屬構件13的表面13a沿著第二凹槽16進行摩擦攪拌接合。表面側流入攪拌工程，在本實施形態中，其包括使塑性流動材Q流入第一空隙部P1的第一表面側流入攪拌工程與使塑性流動材Q流入第二空隙部P2的第二表面側流入攪拌工程。In the surface side inflow stirring process, as shown in Figs. 9b and 9c, friction stir welding is performed from the surface 13a of the second metal member 13 along the second groove 16. The surface side flows into the agitation process, and in the present embodiment, it includes the first surface side in which the plastic fluid material Q flows into the first gap portion P1, and the second surface side in which the plastic fluid material Q flows into the second gap portion P2. Flow into the mixing project.
在第一表面側流入攪拌工程中，從第二金屬構件13的表面13a壓入高速旋轉的流入攪拌用旋轉工具55，使流入攪拌用旋轉工具55沿著第二凹槽16平面呈U字形移動。流入攪拌用旋轉工具55移動使工具本體56的底面57(肩部)的投影部分的一部份與第一空隙部P1重合。In the first surface side inflow agitation process, the inflow agitation rotary tool 55 that is rotated at a high speed is pressed from the surface 13a of the second metal member 13, and the inflow agitation rotary tool 55 is moved in a U shape along the plane of the second groove 16. . The inflow agitation rotating tool 55 moves so that a portion of the projected portion of the bottom surface 57 (shoulder portion) of the tool body 56 coincides with the first gap portion P1.
此時，藉由高速旋轉的銷58，其周圍的第一金屬構件12及第二金屬構件13的鋁合金材料由摩擦熱加熱而塑性流動化。在第二實施形態中，流入攪拌用旋轉工具55的前端壓入至比第一金屬構件12與第二金屬構件13的平接部(V1，V2)還下方的位置，塑性流動化的塑性流動材Q確實地流入第一空隙部P1而與熱媒體用管4接觸。At this time, by the pin 58 that rotates at a high speed, the aluminum alloy material of the first metal member 12 and the second metal member 13 around it is plastically fluidized by frictional heat. In the second embodiment, the tip end of the inflow stirring rotary tool 55 is press-fitted to a position lower than the flat portion (V1, V2) of the first metal member 12 and the second metal member 13, and the plastic flow is plasticized. The material Q surely flows into the first gap portion P1 to come into contact with the heat medium tube 4.
於此，如第9b圖所示，熱媒體用管4的上端，雖然與第二凹槽16相隔微細的間隙而配置，塑性流動材Q流入第一空隙部P1時，塑性流動材Q的熱由熱媒體用管4除去而使流動性降低。因此，塑性流動材Q不流入第二空隙部P2而至流於第一空隙部P1而充填硬化。Here, as shown in Fig. 9b, the upper end of the heat medium tube 4 is disposed with a fine gap from the second groove 16, and the plastic flow material Q flows into the first gap portion P1 to heat the plastic flow material Q. The heat medium tube 4 is removed to lower the fluidity. Therefore, the plastic fluid material Q does not flow into the second void portion P2 but flows to the first void portion P1 to be filled and hardened.
在第二表面側流入攪拌工程中，如第9c圖所示，相對於熱媒體用管4的流動方向Y(參照第2圖)使由摩擦攪拌而塑性流動化的塑性流動材Q流入形成於右上側的第二空隙部P2。第二表面側流入攪拌工程除了是在第二空隙部P2進行之外，由於與第一表面側流入攪拌工程相同而省略其說明。而且，在表面側流入攪拌工程結束之後，切削除去形成於第二金屬構件13的表面13a的毛邊而使表面13a變得平滑。In the second surface side inflow stirring process, as shown in Fig. 9c, the plastic flow material Q which is plastically fluidized by friction stir is introduced into the flow direction Y (see Fig. 2) of the heat medium tube 4 The second gap portion P2 on the upper right side. The second surface side inflow agitation engineering is the same as the first surface side inflow stirring process except that it is performed in the second gap portion P2, and the description thereof will be omitted. Further, after the surface side inflow and agitation process is completed, the burrs formed on the surface 13a of the second metal member 13 are removed to smooth the surface 13a.
根據以上說明的傳熱板的製造方法，在由形成於第一金屬構件12的第一凹槽15與形成於第二金屬構件13的第二凹槽16的空間部K1中，由於空間部K1的高度形成比熱媒體用管4的外徑大，即使在熱媒體用管4的一部份彎曲的情況下，也容易地進行上述的配置工程。According to the above-described method of manufacturing the heat transfer plate, in the space portion K1 formed by the first groove 15 formed in the first metal member 12 and the second groove 16 formed in the second metal member 13, due to the space portion K1 The height is formed larger than the outer diameter of the heat medium tube 4, and the above-described arrangement work can be easily performed even when a part of the heat medium tube 4 is bent.
又，藉由表面側流入攪拌工程，藉由使塑性流動材Q流入形成於熱媒體用管4的周圍的第一空隙部P1及第二空隙部P2，由於可掩埋該空隙部，而可提高傳熱板的熱交換效率。Further, by flowing the plastic flow material Q into the first void portion P1 and the second void portion P2 formed around the heat medium tube 4 by the surface side inflow stirring process, the void portion can be buried, thereby improving Heat exchange efficiency of the heat transfer plates.
而且，在本實施形態中，雖然第一凹槽15的寬度形成與熱媒體用管4的外徑略相同，但並不限定於此，第一凹槽15的寬度也可以形成比熱媒體用管4的外徑大。又，第一凹槽15的底部15a的曲率可形成比熱媒體用管4的曲率小。藉此，可容易地進行插入熱媒體用管4的插入工程以及配置第二金屬構件13的配置工程。Further, in the present embodiment, the width of the first groove 15 is slightly the same as the outer diameter of the heat medium tube 4, but the shape is not limited thereto, and the width of the first groove 15 may be formed as a tube for the heat medium. The outer diameter of 4 is large. Further, the curvature of the bottom portion 15a of the first groove 15 may be formed to be smaller than the curvature of the heat medium tube 4. Thereby, the insertion work for inserting the heat medium tube 4 and the arrangement work of arranging the second metal member 13 can be easily performed.

接著，如第10b圖所示，使接合用旋轉工具50(參照第5圖)沿著平接部V1、V2進行摩擦攪拌接合。藉此，可接合第一金屬構件22與第二金屬構件23。Next, as shown in Fig. 10b, the joining rotary tool 50 (see Fig. 5) is subjected to friction stir welding along the flat portions V1, V2. Thereby, the first metal member 22 and the second metal member 23 can be joined.
接著，如第10c圖所示，從第二金屬構件23的表面23a沿著第二凹槽26進行摩擦攪拌接合。表面側流入攪拌工程，在本實施形態中，其包括使塑性流動材Q流入第一空隙部P1的第一表面側流入攪拌工程與使塑性流動材Q流入第二空隙部P2的第二表面側流入攪拌工程。Next, as shown in Fig. 10c, friction stir welding is performed from the surface 23a of the second metal member 23 along the second groove 26.

Then, after the surface side inflow and agitation process is completed, the burrs formed on the surface 23a of the second metal member 23 are removed and smoothed.
根據以上說明的傳熱板的製造方法，即使第一凹槽25及第二凹槽26都形成曲面，由第一凹槽25及第二凹槽26形成的空間部K2的高度H形成比熱媒體用管4的外徑大，即使在熱媒體用管4的一部份彎曲的情況下，也容易地進行上述的配置工程。According to the manufacturing method of the heat transfer plate described above, even if the first groove 25 and the second groove 26 form a curved surface, the height H of the space portion K2 formed by the first groove 25 and the second groove 26 forms a specific heat medium. The outer diameter of the tube 4 is large, and even in the case where a part of the heat medium tube 4 is bent, the above-described arrangement work is easily performed.
又，藉由表面側流入攪拌工程，藉由使塑性流動材Q流入形成於熱媒體用管4的周圍的第一空隙部P1及第二空隙部P2，由於可掩埋該空隙部，而可提高傳熱板的熱交換效率。Further, by flowing the plastic flow material Q into the first void portion P1 and the second void portion P2 formed around the heat medium tube 4 by the surface side inflow stirring process, the void portion can be buried, thereby improving Heat exchange efficiency of the heat transfer plates.

The preparation process, the joining process in which the joining rotary tool 50 (see FIG. 5) is moved along the flat portions V1 and V2 to perform friction stir welding, and on the surface 33a side of the second metal member 33 and the first metal member 32 The back surface 32b moves the inflow stirring rotary tool 55 to flow the plastic fluid material Q into the first gap portion P1 to the fourth gap portion P4.
準備工程包括形成第一金屬構件32與第二金屬構件33的切削工程、將熱媒體用管4插入形成於第一金屬構件32的第一凹槽35中的插入工程以及將第二金屬構件33配置於第一金屬構件32的配置工程。The preparation process includes cutting work for forming the first metal member 32 and the second metal member 33, inserting the heat medium tube 4 into the first groove 35 formed in the first metal member 32, and inserting the second metal member 33 The configuration work of the first metal member 32 is disposed.
在切削工程中，如第11a圖所示，藉由公知的切削加工，在厚板構件上切出斷面觀看呈矩形的第一凹槽35而形成第一金屬構件32。第一凹槽25的深度形成熱媒體用管4的外徑的1.1倍。又，第一凹槽25的寬度形成熱媒體用管4的外徑的1.1倍。In the cutting process, as shown in Fig. 11a, the first metal member 32 is formed by cutting a first groove 35 having a rectangular cross section by a known cutting process. The depth of the first groove 25 forms 1.1 times the outer diameter of the heat medium tube 4. Further, the width of the first groove 25 forms 1.1 times the outer diameter of the heat medium tube 4.
在插入工程中，如第11b圖所示，熱媒體用管4插入第一金屬構件32的第一凹槽35。In the insertion process, as shown in Fig. 11b, the heat medium tube 4 is inserted into the first recess 35 of the first metal member 32.
在配置工程中，如第11b圖所示，第二金屬構件33配置於第一金屬構件32的上方。熱媒體用管4係配置於由第一凹槽35與第二金屬構件33的底面(下面)33b所形成的空間部K3。此時，如第11b圖所示，熱媒體用管4的下端與第一凹槽35的底面35c接觸，上端與第二金屬構件33的底面33b分離。In the disposition configuration, as shown in FIG. 11b, the second metal member 33 is disposed above the first metal member 32. The heat medium tube 4 is disposed in the space portion K3 formed by the first groove 35 and the bottom surface (lower surface) 33b of the second metal member 33. At this time, as shown in Fig. 11b, the lower end of the heat medium tube 4 is in contact with the bottom surface 35c of the first recess 35, and the upper end is separated from the bottom surface 33b of the second metal member 33.
接著，如第11b及11c圖所示，接合用旋轉工具50(參照第5圖)沿著平接部V1、V2進行摩擦攪拌接合。對於接合工程由於與上述第一實施形態的接合工程相同而省略詳細的說明。Next, as shown in FIGS. 11b and 11c, the joining rotary tool 50 (see FIG. 5) performs friction stir welding along the flat portions V1 and V2. The joining process is the same as that of the joining process of the first embodiment described above, and detailed description thereof will be omitted.
在流入攪拌工程中，使流入攪拌用旋轉工具55從熱媒體用管4及第二金屬構件33所構成的暫時組合構造體U的表面及裡面移動，而使塑性流動材Q流入第一空隙部P1~第四空隙部P4。In the inflow and agitation process, the inflow stirring rotary tool 55 is moved from the surface and the inside of the temporary composite structure U composed of the heat medium tube 4 and the second metal member 33, and the plastic fluid material Q flows into the first gap portion. P1 to fourth gap portion P4.
對於流入攪拌工程由於與上述第一實施形態的接合工程相同而省略詳細的說明。The inflow and agitation process is the same as that of the above-described first embodiment, and detailed description thereof will be omitted.
根據以上說明的第四實施形態的製造方法，即使在第二金屬構件33上不設置凹槽而僅在第一金屬構件32上設置第一凹槽35，藉由第一凹槽35的寬度及深度形成比熱媒體用管4的外徑還大，可得到與第一實施形態大略相同的效果。又，由於不必在第二金屬構件33上形成第二凹槽，因此可節省作業手續。又，在配置工程中，在第二金屬構件33上不形成第二凹槽，使配置作業變得容易。According to the manufacturing method of the fourth embodiment described above, even if the second metal member 33 is not provided with the groove, only the first groove 35 is provided on the first metal member 32, by the width of the first groove 35 and The depth formation is larger than the outer diameter of the heat medium tube 4, and the same effect as that of the first embodiment can be obtained. Moreover, since it is not necessary to form the second groove on the second metal member 33, the work procedure can be saved. Further, in the disposition process, the second recess is not formed on the second metal member 33, which facilitates the arranging operation.
而且，第一凹槽35雖然在本實施形態斷面形成矩形，但並不限定於此，形成包含曲面亦可。又，流入攪拌工程雖然在第一金屬構件32、熱媒體用管4及第二金屬構件33所構成的暫時組合構造體U的表面及背面進行，由空間部K3與熱媒體用管4的形狀從表面進行亦可。此時，參照第11c圖，當從第二金屬構件33的表面33a進行流入攪拌工程時，塑性流動材Q流入第一空隙部P1與第二空隙部P2之同時，第一金屬構件32與第二金屬構件33平接的部分的平接部V(V1，V2)進行摩擦攪拌。藉此，可接合第一金屬構件32與第二金屬構件33。又，此時，流入攪拌用旋轉工具55的前端最好到達比平接部V還深的位置進行流入攪拌工程。藉此，可確實地進行第一金屬構件32與第二金屬構件33的接合以及使塑性流動材Q流入第一空隙部P1與第二空隙部P2的作業。Further, although the first groove 35 has a rectangular cross section in the present embodiment, the first groove 35 is not limited thereto, and may include a curved surface. Further, the inflow and agitation process is performed on the front surface and the back surface of the temporary composite structure U composed of the first metal member 32, the heat medium tube 4, and the second metal member 33, and the space portion K3 and the shape of the heat medium tube 4 are formed. It can also be done from the surface. At this time, referring to FIG. 11c, when the inflowing process is performed from the surface 33a of the second metal member 33, the plastic flow material Q flows into the first gap portion P1 and the second gap portion P2, and the first metal member 32 and the The flat portion V (V1, V2) of the flat portion of the two metal members 33 is subjected to friction stirring. Thereby, the first metal member 32 and the second metal member 33 can be joined. Moreover, at this time, it is preferable that the front end of the inflow stirring rotary tool 55 reaches a position deeper than the flat portion V and flows into the stirring process. Thereby, the joining of the first metal member 32 and the second metal member 33 and the operation of flowing the plastic fluid material Q into the first gap portion P1 and the second gap portion P2 can be surely performed.
又，在第一實施形態~第四實施形態中，雖然在流入攪拌工程中所使用的流入攪拌用旋轉工具55比接合工程中所使用的接合用旋轉工具50還大型，但也可以使用接合工程中的流入攪拌用旋轉工具55。如此，可統一在各工程中所使用的旋轉工具，可省略旋轉工具的交換時間，可縮短施工時間。Further, in the first to fourth embodiments, the inflow agitation rotary tool 55 used in the inflow and agitation process is larger than the joining rotary tool 50 used in the joining process, but the joining process may be used. The inflow stirring tool 55 flows. In this way, the rotary tool used in each project can be unified, and the exchange time of the rotary tool can be omitted, and the construction time can be shortened.

在熔接工程中，沿著在上述準備工程中所形成的暫時組合構造體(第一金屬構件2、第二金屬構件3及熱媒體用管4)的側面的平接部V(V1，V2)進行熔接。在熔接工程中的熔接種類並無特別限制，而進行MIG熔接或TIG熔接等的隆起熔接，最好以熔接金屬T覆蓋平接部V1、V2。如此，藉由進行熔接工程，由於在第一金屬構件2與第二金屬構件3固定的狀態下進行流入攪拌工程，因此可提高流入攪拌工程的作業性。而且，在熔接工程中可橫越平接部V1、V2的全長進行熔接，也可以既定的間隔斷續地進行熔接。又，在熔接工程中，沿著平接部V1、V2形成槽，而使熔接金屬T填充於該槽。In the welding process, the flat portion V (V1, V2) of the side surface of the temporary composite structure (the first metal member 2, the second metal member 3, and the heat medium tube 4) formed in the above-described preparation process Perform welding. The type of welding in the welding process is not particularly limited, and it is preferable to cover the flat portions V1 and V2 with the welded metal T by performing ridge welding such as MIG welding or TIG welding. By performing the welding process, the inflowing agitation process is performed in a state in which the first metal member 2 and the second metal member 3 are fixed, so that the workability in the inflowing process can be improved. Further, in the welding process, the entire length of the flat portions V1 and V2 may be fused, and the welding may be intermittently performed at predetermined intervals. Further, in the welding process, grooves are formed along the flat portions V1, V2, and the welded metal T is filled in the grooves.

In other words, the inflow agitation process includes moving the inflow agitation rotary tool 55 on the surface 211 of the second metal member 210 to cause the plastic flow material Q to flow into the surface side of the first gap portion P21 and the second gap portion P22 to flow into the agitation process and to flow in. The stirring rotary tool 55 moves on the back surface 204 of the first metal member 210 to flow the plastic flow material Q into the back side of the third gap portion P23 and the fourth gap portion P24 to flow into the stirring process. The inflow stirring tool 55 is used in the same manner as in the first embodiment.
而且，在表面側流入攪拌工程中，使塑性流動材Q流入第一空隙部P21的工程為第一表面側流入攪拌工程，使塑性流動材Q流入第二空隙部P22的工程為第二表面側流入攪拌工程。又，使塑性流動材Q流入第三空隙部P23的工程為第一背面側流入攪拌工程，使塑性流動材Q流入第四空隙部P24的工程為第二背面側流入攪拌工程。Further, in the surface side inflow stirring process, the process of flowing the plastic flowing material Q into the first gap portion P21 is the first surface side flowing into the stirring process, and the process of flowing the plastic flowing material Q into the second gap portion P22 is the second surface side. Flow into the mixing project. Further, the process of flowing the plastic fluid material Q into the third gap portion P23 is the first back side flow inflow stirring process, and the process of flowing the plastic fluid material Q into the fourth gap portion P24 is the second back side flow inflowing process.
在第一表面側流入攪拌工程中，如第5d圖所示，相對於熱媒體用管216的流動方向Y(參照第2圖)，使藉由摩擦攪拌而塑性流動化的塑性流動材Q流入形成於左上側的第一空隙部P21。In the first surface side inflow stirring process, as shown in Fig. 5d, the plastic flow material Q which is plastically fluidized by friction stir is flown in the flow direction Y of the heat medium tube 216 (see Fig. 2).

At this time, the aluminum alloy material of the second metal member 210 around it is plastically fluidized by frictional heat heating by the pin 58 rotated at a high speed. Since the inflowing stirring rotary tool 55 is pressed at a predetermined depth, the plastic fluidized plastic flow material Q flows into the first gap portion P21 and comes into contact with the heat medium tube 216.
於此，如第17b圖所示，雖然熱媒體用管216的左右端及上端係與第一凹槽208及第二凹槽215以微細間隙配置，當塑性流動材Q流入第一空隙部P21時，塑性流動材Q的熱由於被熱媒體用管216吸收而使流動性降低。因此，流入第一空隙部P21的塑性流動材Q不會流入第二空隙部P22及第三空隙部P23而滯留在第一空隙部P21充填而硬化。Here, as shown in FIG. 17b, the left and right ends and the upper end of the heat medium tube 216 are arranged with a fine gap between the first groove 208 and the second groove 215, and the plastic flow material Q flows into the first gap portion P21. At the time, the heat of the plastic fluid material Q is absorbed by the heat medium tube 216, and the fluidity is lowered. Therefore, the plastic flowing material Q flowing into the first gap portion P21 does not flow into the second gap portion P22 and the third gap portion P23, and stays in the first gap portion P21 to be filled and hardened.
在第二表面側流入攪拌工程中，如第18a圖所示，相對於熱媒體用管216的流動方向Y(參照第2圖)，使由摩擦攪拌而塑性流動化的塑性流動材Q流入第二空隙部P22。第二表面側流入攪拌工程除了是在第二空隙部P22進行之外，其餘與第一表面側流入攪拌工程相同，因此省略其說明。而且，在表面側流入攪拌工程結束之後，切削除去形成於第一金屬構件202的表面203的毛邊，而使表面203變得平滑。In the second surface side inflow stirring process, as shown in Fig. 18a, the plastic flow material Q which is plastically fluidized by friction stir is flown into the flow direction Y (see Fig. 2) of the heat medium tube 216. Two void portions P22. The second surface side inflow agitation process is the same as the first surface side inflow stirring process except that it is performed in the second gap portion P22, and thus the description thereof will be omitted. Further, after the surface side inflow and agitation process is completed, the burrs formed on the surface 203 of the first metal member 202 are removed by cutting, and the surface 203 is smoothed.
在背面側流入攪拌工程中，如第18b圖所示，在第一金屬構件202表面及背面反轉之後，進行背面側流入攪拌工程。即，在背面側流入攪拌工程中，在第一金屬構件202的背面204使流入攪拌用旋轉工具55沿著第一凹槽208移動而將由摩擦熱而塑性流動化的的塑性流動材Q流入第三空隙部P23及第四空隙部P24。背面側流入攪拌工程在本實施形態中，包括使塑性流動材流入第三空隙部P23的第一背面側流入攪拌工程以及使塑性流動材流入第四空隙部P24的第二背面側流入攪拌工程。When the back side flows into the stirring process, as shown in Fig. 18b, after the surface and the back surface of the first metal member 202 are reversed, the back side inflow stirring process is performed. In other words, in the back side flow-inflowing process, the inflowing stirring rotary tool 55 is moved along the first groove 208 on the back surface 204 of the first metal member 202 to flow the plastic fluid material Q which is plastically fluidized by frictional heat. Three void portions P23 and fourth void portions P24. In the present embodiment, the back side inflow and agitation process includes a first back surface side in which the plastic fluid material flows into the third gap portion P23, and a second back side flow in which the plastic fluid material flows into the fourth gap portion P24.
在第一背面側流入攪拌工程中，使摩擦攪拌而塑性流動化的塑性流動材流入第三空隙部P23。在第一背面側流入攪拌工程中，在第一金屬構件202的背面204壓入高速旋轉的流入攪拌用旋轉工具55，沿著第一凹槽208使流入攪拌用旋轉工具55以平面觀看呈U字形的軌跡移動。流入攪拌用旋轉工具55移動使工具本體56的底面57(肩部)的投影部分的一部份與熱媒體用管216的第三空隙部P23重疊。此時，藉由高速旋轉的銷58，其周圍的第一金屬構件202的鋁合金材料由於摩擦熱加熱而塑性流動化。流入攪拌用旋轉工具55由於壓入既定深度，塑性流動化的塑性流動材Q流入第三空隙部P23，並與熱媒體用管216接觸。The plastic flow material which is frictionally stirred and plastically fluidized flows into the third gap portion P23 while flowing into the stirring process on the first back side. In the first back side flow inflow stirring process, a high-speed rotating inflow stirring rotary tool 55 is press-fitted into the back surface 204 of the first metal member 202, and the inflow stirring rotary tool 55 is viewed in a plane along the first groove 208. The trajectory of the glyph moves. The inflow stirring tool 55 moves so that a part of the projected portion of the bottom surface 57 (shoulder portion) of the tool body 56 overlaps with the third gap portion P23 of the heat medium tube 216. At this time, the aluminum alloy material of the first metal member 202 around it is plastically fluidized by frictional heat heating by the pin 58 rotated at a high speed. When the inflow stirring tool 55 is pressed in a predetermined depth, the plastic fluid material Q which is plastically fluidized flows into the third gap portion P23 and comes into contact with the heat medium tube 216.
在第二背面側流入攪拌工程中，如第18c圖所示，由摩擦攪拌而塑性流動化的塑性流動材Q流入第四空隙部P24。第二背面側流入攪拌工程除了是在第四空隙部P24進行之外，其餘與第一背面側流入攪拌工程相同，因此省略其說明。而且，在背面側流入攪拌工程結束之後，最好切削除去形成於第一金屬構件202的背面204的毛邊，而使背面204變得平滑。In the second back side flowing into the stirring process, as shown in Fig. 18c, the plastic fluid material Q which is plastically fluidized by friction stirring flows into the fourth gap portion P24. The second back side inflow stirring process is the same as the first back side inflow stirring process except for the fourth gap portion P24, and therefore the description thereof will be omitted. Further, after the completion of the inflow and the agitation process on the back side, it is preferable to cut off the burrs formed on the back surface 204 of the first metal member 202 to smooth the back surface 204.
而且，在表面側流入攪拌工程及背面側流入攪拌工程中，根據第一空隙部P21~第四空隙部P24的形狀及大小，設定流入攪拌用旋轉工具55的壓入量及插入位置等。熱媒體用管216不會崩潰的程度，使流入攪拌用旋轉工具55接近而使塑性流動材Q無間隙地流入第一空隙部P21~第四空隙部P24。In addition, in the surface side inflow stirring process and the back side inflow stirring process, the pressing amount, the insertion position, and the like which flow into the stirring rotary tool 55 are set according to the shape and size of the first gap portion P21 to the fourth gap portion P24. To the extent that the heat medium tube 216 does not collapse, the inflowing stirring rotary tool 55 approaches, and the plastic fluid material Q flows into the first gap portion P21 to the fourth gap portion P24 without a gap.
例如，如第19圖所示，流入攪拌用旋轉工具55的銷58的前端最好插入得比第二凹槽215的頂面215c還深。又，流入攪拌用旋轉工具55的銷58的前端與連接於熱媒體用管216的假想鉛直面的最接近距離最好是1~3mm。藉此，在使熱媒體用管216不崩壞的程度上使塑性流動材Q流入第一空隙部P21。當最接近距離L小於1mm時，流入攪拌用旋轉工具55接近熱媒體用管216，熱媒體用管216有崩壞的可能性。又，當最接近距離L大於3mm時，塑性流動材Q可能不流入第一空隙部P21。For example, as shown in Fig. 19, the front end of the pin 58 that flows into the stirring rotary tool 55 is preferably inserted deeper than the top surface 215c of the second recess 215. Further, the closest distance between the tip end of the pin 58 that flows into the stirring rotary tool 55 and the virtual vertical surface that is connected to the heat medium tube 216 is preferably 1 to 3 mm. Thereby, the plastic fluid material Q flows into the first gap portion P21 to such an extent that the heat medium tube 216 does not collapse. When the closest distance L is less than 1 mm, the inflow stirring rotary tool 55 approaches the heat medium tube 216, and the heat medium tube 216 may collapse. Also, when the closest distance L is larger than 3 mm, the plastic flowing material Q may not flow into the first gap portion P21.
又，流入攪拌用旋轉工具55的壓入量(壓入長度)在第一表面側流入攪拌工程中，工具本體56壓退的第二金屬構件210的金屬的體積相等於填充於第一空隙部P21的塑性流動化的鋁合金材料的體積以及塑性化區域W23的寬度方向兩側產生的毛邊的體積的和的長度。Further, the press-in amount (press-in length) of the inflow stirring rotary tool 55 flows into the stirring process on the first surface side, and the metal of the second metal member 210 that is retracted by the tool body 56 is equal in volume to the first gap portion. The volume of the plastically fluidized aluminum alloy material of P21 and the sum of the volumes of the burrs generated on both sides in the width direction of the plasticized region W23.
根據以上說明的傳熱板的製造方法，由形成於第一金屬構件202的第一凹槽208與形成於第二金屬構件210的背面212的第二凹槽215所構成的空間部K中，由於空間部K的寬度及高度形成比熱媒體用管216的外徑大，即使在熱媒體用管216的一部份彎曲的情況下，也容易地進行上述插入工程及蓋槽閉塞工程。According to the above-described method of manufacturing the heat transfer plate, the space portion K formed by the first groove 208 formed in the first metal member 202 and the second groove 215 formed in the back surface 212 of the second metal member 210 is Since the width and height of the space portion K are larger than the outer diameter of the heat medium tube 216, even when a part of the heat medium tube 216 is bent, the above-described insertion work and lid groove closing work can be easily performed.
又，藉由表面側流入攪拌工程及背面側流入攪拌工程，藉由使塑性流動材Q流入形成於熱媒體用管216的周圍的第一空隙部P21~第四空隙部P24，由於可掩埋該空隙部，可提高傳熱板201的熱交換效率。In addition, the first gap portion P21 to the fourth gap portion P24 formed around the heat medium tube 216 can be buried by the surface side inflow stirring process and the back side inflow stirring process. The void portion can improve the heat exchange efficiency of the heat transfer plate 201.
又，根據本實施形態，在表面側流入攪拌工程之前，使用比較小的接合用旋轉工具50而接合第一金屬構件202與第二金屬構件210，因此在表面側流入攪拌工程中，在確實地固定第二金屬構件210的狀態下可進行摩擦攪拌。因此，使用比較大的流入攪拌用旋轉工具55而以大的壓入力作用的摩擦攪拌接合可在穩定的狀態下進行。Further, according to the present embodiment, since the first metal member 202 and the second metal member 210 are joined by using the relatively small joining rotary tool 50 before the surface side flows into the stirring process, the surface side flows into the stirring process, and is surely Friction stirring can be performed in a state where the second metal member 210 is fixed. Therefore, the friction stir welding using a relatively large inflow stirring rotary tool 55 with a large press-in force can be performed in a stable state.
而且，在本實施形態中，雖然在接合工程後進行表面側流入攪拌工程，也可以在表面側流入攪拌工程之後進行接合工程。此時，若將第二金屬構件210在長度方向以未圖示的治具固定，則在第二金屬構件210的寬度方向藉由第一金屬構件202固定，表面側流入攪拌工程中的摩擦攪拌可以在確實地固定第二金屬構件210的狀態下進行。Further, in the present embodiment, the surface side inflow stirring process is performed after the joining process, and the joining process may be performed after the surface side flows into the stirring process. At this time, when the second metal member 210 is fixed in the longitudinal direction by a jig (not shown), the second metal member 210 is fixed in the width direction of the second metal member 210 by the first metal member 202, and the surface side flows into the friction stir in the stirring process. It can be performed in a state where the second metal member 210 is surely fixed.
又，在本實施形態中，在接合工程中，雖然橫越平接部V21、V22的全長而實施摩擦攪拌接合，但並不限定於此，沿著平接部V21、V22相隔既定間隔而斷續地實施摩擦攪拌接合亦可，將第二金屬構件210暫時安裝於第一金屬構件202上。根據如此的傳熱板的製造方法，可減低接合工程所需的手續與時間。Further, in the present embodiment, the friction stir welding is performed across the entire length of the flat portions V21 and V22 in the joining process, but the present invention is not limited thereto, and the flat portions V21 and V22 are separated by a predetermined interval. The second metal member 210 may be temporarily attached to the first metal member 202 by continuously performing friction stir welding. According to such a method of manufacturing a heat transfer plate, the procedures and time required for the joining process can be reduced.
又，如前所述，可進行熔接工程取代接合工程，在熔接工程中，可對平接部V1、V2連續地進行熔接，也可以斷續地進行熔接。Further, as described above, the welding process can be performed instead of the joining process, and in the welding process, the flat portions V1 and V2 can be continuously welded or intermittently welded.
接著，針對本發明的第七實施形態做說明。第七實施形態的傳熱板的製造方法中，就不進行背面側流入攪拌工程的特徵、在接合工程中形成的塑性化區域與表面側流入攪拌工程所形成的塑性化區域重複的特徵而言，是與第六實施形態不同的。而且，雖然未具體圖示，熱媒體用管216與第一實施形態相同呈平面U字形。Next, a seventh embodiment of the present invention will be described. In the method for producing a heat transfer plate according to the seventh embodiment, the feature of not performing the back side inflow stirring process, the plasticized region formed in the joining process, and the plasticized region formed by the surface side inflow stirring process are repeated. It is different from the sixth embodiment. Further, although not specifically illustrated, the heat medium tube 216 has a flat U-shape as in the first embodiment.
第七實施形態的傳熱板的製造方法，如第20圖及第21圖所示，其包括在形成第一金屬構件202及第二金屬構件210之同時，將熱媒體管216及及第二金屬構件210配置於第一金屬構件202的準備工程、使接合用旋轉工具50沿著平接部V21、V22移動而進行摩擦攪拌接合的接合工程以及從第二金屬構件210的表面211側使流入攪拌用旋轉工具55移動而使塑性流動材Q流入第一空隙部P21及第二空隙部P22的表面側流入攪拌工程。The method for manufacturing the heat transfer plate according to the seventh embodiment, as shown in FIGS. 20 and 21, includes forming the first metal member 202 and the second metal member 210, and the heat medium tube 216 and the second The metal member 210 is disposed in a preparation process of the first metal member 202, a joining process in which the joining rotary tool 50 is moved along the flat portions V21 and V22 to perform friction stir welding, and an inflow from the surface 211 side of the second metal member 210. The stirring rotary tool 55 moves to cause the plastic flow material Q to flow into the first gap portion P21 and the surface side of the second gap portion P22 to flow into the stirring process.
準備工程包括形成第一金屬構件202與第二金屬構件210的切削工程、將熱媒體用管216插入形成於第一金屬構件202的第一溝槽238中的插入工程以及將第二金屬構件210配置於蓋槽206的蓋槽閉塞工程。The preparation process includes forming a cutting process of the first metal member 202 and the second metal member 210, inserting the heat medium tube 216 into the first groove 238 formed in the first metal member 202, and inserting the second metal member 210 The cover groove disposed in the cover groove 206 is closed.
在切削工程中，如第20a圖所示，藉由公知的切削加工，在厚板構件上形成蓋槽206。然後，由切削加工在蓋槽206的底面206c切出開口朝向上方而斷面觀看呈U字形的第一凹槽238。第一凹槽238的底部237係切成圓弧狀，形成與熱媒體用管216相同的曲率。第一凹槽238的深度形成比熱媒體用管216的外徑小，第一凹槽238的寬度形成大略與熱媒體用管216的外徑相等。In the cutting process, as shown in Fig. 20a, a cover groove 206 is formed on the thick plate member by a known cutting process. Then, the first groove 238 having a U-shaped cross section is cut out from the bottom surface 206c of the cover groove 206 by cutting. The bottom portion 237 of the first recess 238 is cut into an arc shape to have the same curvature as the heat medium tube 216. The depth of the first groove 238 is formed smaller than the outer diameter of the heat medium tube 216, and the width of the first groove 238 is formed to be substantially equal to the outer diameter of the heat medium tube 216.
接著，藉由公知的切削加工，在厚板構件上切出剖面呈矩形的第二凹槽245而形成第二金屬構件210。第二凹槽245的寬度形成大略與熱媒體用管216的外徑相等。又，第二凹槽245的深度，如第20b圖所示，在熱媒體管216及第二金屬構件210配置於第一金屬構件202之同時，第二凹槽245的頂面245c與熱媒體用管216分隔微細的間隙。Next, the second metal member 210 is formed by cutting a second recess 245 having a rectangular cross section on the thick plate member by a known cutting process. The width of the second groove 245 is formed to be substantially equal to the outer diameter of the heat medium tube 216. Moreover, the depth of the second recess 245, as shown in FIG. 20b, while the thermal medium tube 216 and the second metal member 210 are disposed on the first metal member 202, the top surface 245c of the second recess 245 and the thermal medium The tube 216 separates the fine gaps.
在插入工程中，如第20b圖所示，熱媒體用管216插入第一凹槽238。此時，熱媒體用管216的下半部與第一凹槽238的底面237接觸。而且，熱媒體用管216的上端位於比蓋槽206的底面206c還上方的位置。In the insertion process, as shown in Fig. 20b, the heat medium tube 216 is inserted into the first recess 238. At this time, the lower half of the heat medium tube 216 is in contact with the bottom surface 237 of the first recess 238. Further, the upper end of the heat medium tube 216 is located above the bottom surface 206c of the cover groove 206.
在蓋槽閉塞工程中，如第20b圖所示，將熱媒體用管216的上部插入形成於第二金屬構件210的第二凹槽245中，同時將第二金屬構件210配置於第一金屬構件202的蓋槽206內。此時，熱媒體用管216與形成於第二金屬構件210的背面212的第二凹槽245的兩直立面245a、245b及頂面245c以微細的間隙分離。即，第一凹槽238與第二凹槽245所形成的空間部K1的寬度係形成與熱媒體用管216的外徑大略相同，空間部K1的高度H形成比熱媒體用管216的外徑大。又，第二金屬構件210的表面211與第一金屬構件202的表面203齊平。In the cover groove occlusion process, as shown in FIG. 20b, the upper portion of the heat medium tube 216 is inserted into the second groove 245 formed in the second metal member 210 while the second metal member 210 is disposed on the first metal. The cover 202 of the member 202 is inside. At this time, the heat medium tube 216 and the two vertical faces 245a and 245b and the top surface 245c of the second groove 245 formed on the back surface 212 of the second metal member 210 are separated by a fine gap. That is, the width of the space portion K1 formed by the first groove 238 and the second groove 245 is formed to be substantially the same as the outer diameter of the heat medium tube 216, and the height H of the space portion K1 is formed to be larger than the outer diameter of the heat medium tube 216. Big. Also, the surface 211 of the second metal member 210 is flush with the surface 203 of the first metal member 202.
於此，在空間部K1中，形成於熱媒體用管216的周圍的空隙部中，相對於流動方向Y(參照第14圖)，以形成於左上側的部分為第一空隙部P21，形成於右上的部分為第二空隙部P22。In the space portion K1, in the gap portion formed around the heat medium tube 216, the portion formed on the upper left side is the first gap portion P21 with respect to the flow direction Y (see FIG. 14). The upper right portion is the second gap portion P22.
接著，在接合工程中，如第21a圖所示，使用接合用旋轉工具50沿著平接部V21、V22進行摩擦攪拌接合。藉此，可接合第一金屬構件202與第二金屬構件210。Next, in the joining process, as shown in FIG. 21a, friction stir welding is performed along the flat portions V21 and V22 using the joining rotary tool 50. Thereby, the first metal member 202 and the second metal member 210 can be joined.
接著，在表面側流入攪拌工程中，如第21b圖及第21c圖所示，從第二金屬構件210的表面211沿著第二凹槽245進行摩擦攪拌。表面側流入攪拌工程，在本實施形態中，其包括使塑性流動材Q流入第一空隙部P21的第一表面側流入攪拌工程與使塑性流動材Q流入第二空隙部P22的第二表面側流入攪拌工程。Next, in the surface side inflow stirring process, as shown in Figs. 21b and 21c, friction stir is performed from the surface 211 of the second metal member 210 along the second groove 245. The surface side flows into the agitation process, and in the present embodiment, it includes the first surface side in which the plastic fluid material Q flows into the first gap portion P21, and the second surface side in which the plastic fluid material Q flows into the second gap portion P22. Flow into the mixing project.
在第一表面側流入攪拌工程中，從第二金屬構件210的表面211壓入高速旋轉的流入攪拌用旋轉工具55，使流入攪拌用旋轉工具55沿著第二凹槽245平面呈U字形移動。流入攪拌用旋轉工具55移動使工具本體56的底面57(肩部)的投影部分的一部份與第一空隙部P21重合之同時，由摩擦攪拌所形成的塑性化區域W23包含W21、W22。即，在第一表面側流入攪拌工程中，在由接合工程所形成的塑性化區域W21、W22上，在表面側流入攪拌工程中移動流入攪拌用旋轉工具55，而對塑性化區域W21、W22做再攪拌。In the first surface side inflow agitation process, the inflow agitation rotary tool 55 that is rotated at a high speed is pressed from the surface 211 of the second metal member 210, and the inflow agitation rotary tool 55 is moved in a U shape along the plane of the second groove 245. . The inflow stirring tool 55 moves so that a part of the projection portion of the bottom surface 57 (shoulder portion) of the tool body 56 overlaps the first gap portion P21, and the plasticized region W23 formed by friction stir includes W21 and W22. In other words, in the first surface side inflow and agitation process, in the plasticized regions W21 and W22 formed by the joining process, the agitation rotating tool 55 is moved in the surface side inflow stirring process, and the plasticized regions W21 and W22 are applied. Do it again.
此時，藉由高速旋轉的銷58，其周圍的第一金屬構件202及第二金屬構件210的鋁合金材料由摩擦熱加熱而塑性流動化。在第七實施形態中，由於流入攪拌用旋轉工具55的前端壓入至比蓋槽206的底面206c還下方的位置，塑性流動化的塑性流動材Q確實地流入第一空隙部P21而與熱媒體用管216接觸。At this time, the aluminum alloy material of the first metal member 202 and the second metal member 210 around the high-speed rotating pin 58 is plastically fluidized by frictional heat. In the seventh embodiment, the tip end of the inflowing stirring rotary tool 55 is pushed into a position below the bottom surface 206c of the cover groove 206, and the plastic fluidized material Q that is plastically fluidized flows into the first gap portion P21 and is heated. The media is in contact with the tube 216.
於此，如第21b圖所示，熱媒體用管216的上端，雖然與第二凹槽245相隔微細的間隙而配置，塑性流動材Q流入第一空隙部P21時，塑性流動材Q的熱由熱媒體用管216除去而使流動性降低。因此，塑性流動材Q不流入第二空隙部P22而至流於第一空隙部P21而充填硬化。Here, as shown in Fig. 21b, the upper end of the heat medium tube 216 is disposed with a fine gap from the second groove 245, and the plastic flow material Q flows into the first gap portion P21 to heat the plastic flow material Q. The heat medium tube 216 is removed to lower the fluidity. Therefore, the plastic fluid material Q does not flow into the second void portion P22 but flows to the first void portion P21 to be filled and hardened.
在第二表面側流入攪拌工程中，如第21c圖所示，相對於熱媒體用管216的流動方向Y(參照第14圖)使由摩擦攪拌而塑性流動化的塑性流動材Q流入形成於右上側的第二空隙部P22。第二表面側流入攪拌工程除了是在第二空隙部P22進行之外，由於與第一表面側流入攪拌工程相同而省略其說明。In the second surface side inflow stirring process, as shown in Fig. 21c, the plastic flow material Q which is plastically fluidized by friction stir is introduced into the flow direction Y (see Fig. 14) of the heat medium tube 216. The second gap portion P22 on the upper right side. The second surface side inflow and agitation engineering is the same as the first surface side inflow stirring process except for the second gap portion P22, and the description thereof will be omitted.
根據以上說明的傳熱板的製造方法，在由形成於第一金屬構件202的第一凹槽238與形成於第二金屬構件210的背面212的第二凹槽245的空間部K1中，由於空間部K1的高度形成比熱媒體用管4的外徑大，即使在熱媒體用管216的一部份彎曲的情況下，也容易地進行上述的蓋槽閉塞工程。According to the above-described method of manufacturing the heat transfer plate, in the space portion K1 formed by the first groove 238 formed in the first metal member 202 and the second groove 245 formed on the back surface 212 of the second metal member 210, The height of the space portion K1 is larger than the outer diameter of the heat medium tube 4, and the above-described lid groove closing process can be easily performed even when a part of the heat medium tube 216 is bent.
又，藉由表面側流入攪拌工程，藉由使塑性流動材Q流入形成於熱媒體用管216的周圍的第一空隙部P21及第二空隙部P22，由於可掩埋該空隙部，而可提高傳熱板231的熱交換效率。又，由於形成於第一金屬構件202的第一凹槽238與熱媒體用管216做面接觸，可省略從第一金屬構件202的背面204進行的流入攪拌工程(背面側流入攪拌工程)。In addition, by flowing the plastic flow material Q into the first gap portion P21 and the second gap portion P22 formed around the heat medium tube 216 by the surface side inflow stirring process, the gap portion can be buried, thereby improving The heat exchange efficiency of the heat transfer plate 231. Further, since the first groove 238 formed in the first metal member 202 is in surface contact with the heat medium tube 216, the inflow stirring process from the back surface 204 of the first metal member 202 (the back side inflow stirring process) can be omitted.
又，在表面側流入攪拌工程所形成的塑性化區域W23中，由於包含在接合工程形成的塑性化區域W21、W22，可使露出於傳熱板231的表面的塑性化區域變小。Further, in the plasticized region W23 formed by the surface side inflow and agitation engineering, the plasticized regions W21 and W22 formed in the joining process are included, and the plasticized region exposed on the surface of the heat transfer plate 231 can be made small.
而且，在本實施形態中，雖然第一凹槽238的寬度形成與熱媒體用管216的外徑大略相同，但並不限定於此，第一凹槽238的寬度也可以形成比熱媒體用管216的外徑大。又，底部237的曲率可形成比熱媒體用管216的曲率小。藉此，可容易地進行插入熱媒體用管216的插入工程以及配置第二金屬構件210的蓋槽閉塞工程。Further, in the present embodiment, the width of the first groove 238 is substantially the same as the outer diameter of the heat medium tube 216, but the shape is not limited thereto, and the width of the first groove 238 may be formed as a tube for the heat medium. The outer diameter of 216 is large. Further, the curvature of the bottom portion 237 may be formed to be smaller than the curvature of the heat medium tube 216. Thereby, the insertion work for inserting the heat medium tube 216 and the lid groove closing process of arranging the second metal member 210 can be easily performed.

在切削工程中，如第22a圖所示，於第一斤屬構件202所形成的蓋槽206的底面206c上形成第一凹槽258。第一凹槽258平面觀看成U字形而斷面觀看呈半圓形。第一凹槽258的半徑與熱媒體用管216的半徑相等。In the cutting process, as shown in Fig. 22a, a first groove 258 is formed in the bottom surface 206c of the cover groove 206 formed by the first ball member 202. The first groove 258 is viewed in a U-shape in plan view and is semi-circular in cross-section. The radius of the first groove 258 is equal to the radius of the heat medium tube 216.
又，同樣地，在第二金屬構件260的背面262形成第二凹槽265。第二凹槽265向下方開口，開口部的寬度形成與熱媒體用管216的外徑大略相等。又，第二凹槽265的頂面265c的曲率形成比熱媒體用管216的曲率大。Also, similarly, the second recess 265 is formed on the back surface 262 of the second metal member 260. The second groove 265 is opened downward, and the width of the opening is formed to be substantially equal to the outer diameter of the heat medium tube 216. Further, the curvature of the top surface 265c of the second groove 265 is formed larger than the curvature of the heat medium tube 216.
在插入工程中，如第22b圖所示，熱媒體用管216的下半部插入第一凹槽258。熱媒體用管216的下半部與第一凹槽258做面接觸。In the insertion process, as shown in Fig. 22b, the lower half of the heat medium tube 216 is inserted into the first recess 258. The lower half of the heat medium tube 216 is in surface contact with the first groove 258.
在蓋槽閉塞工程中，如第22b圖所示，將熱媒體用管216的上部插入形成於第二金屬構件260的第二凹槽265中，同時將第二金屬構件260插入蓋槽206內。第一凹槽258與第二凹槽265重合而形成的空間部K2的高度H形成比熱媒體用管216的外徑大。In the cover groove occlusion process, as shown in FIG. 22b, the upper portion of the heat medium tube 216 is inserted into the second groove 265 formed in the second metal member 260 while the second metal member 260 is inserted into the cover groove 206. . The height H of the space portion K2 formed by the first groove 258 and the second groove 265 being overlapped is formed larger than the outer diameter of the heat medium tube 216.
於此，在形成於熱媒體用管216的周圍的空隙部中，相對於流動方向Y(參照第14圖)，以形成於左上側的部分為第一空隙部P21，形成於右上的部分為第二空隙部P22。又，第二金屬構件260的表面261與第一金屬構件202的表面203齊平。Here, in the gap portion formed around the heat medium tube 216, the portion formed on the upper left side is the first gap portion P21 with respect to the flow direction Y (see FIG. 14), and the portion formed on the upper right side is The second gap portion P22. Also, the surface 261 of the second metal member 260 is flush with the surface 203 of the first metal member 202.
接著，如第22b圖所示，使用接合用旋轉工具50沿著平接部V21、V22進行摩擦攪拌接合。藉此，可接合第一金屬構件202與第二金屬構件260。Next, as shown in Fig. 22b, friction stir welding is performed along the flat portions V21 and V22 using the joining rotary tool 50. Thereby, the first metal member 202 and the second metal member 260 can be joined.
接著，如第22c圖所示，從第二金屬構件260的表面261沿著第二凹槽265進行摩擦攪拌接合。表面側流入攪拌工程，在本實施形態中，其包括使塑性流動材Q流入第一空隙部P21的第一表面側流入攪拌工程與使塑性流動材Q流入第二空隙部P22的第二表面側流入攪拌工程。Next, as shown in Fig. 22c, friction stir welding is performed from the surface 261 of the second metal member 260 along the second groove 265. The surface side flows into the agitation process, and in the present embodiment, it includes the first surface side in which the plastic fluid material Q flows into the first gap portion P21, and the second surface side in which the plastic fluid material Q flows into the second gap portion P22. Flow into the mixing project.
在第一表面側流入攪拌工程中，從第二金屬構件260的表面261壓入高速旋轉的流入攪拌用旋轉工具55，使流入攪拌用旋轉工具55沿著第二凹槽265以平面觀看呈U字形移動。流入攪拌用旋轉工具55移動使工具本體56的底面57(肩部)的投影部分的一部份與第一空隙部P21重合。此時，藉由高速旋轉的銷58，其周圍的第二金屬構件260的鋁合金材料由摩擦熱加熱而塑性流動化。由於流入攪拌用旋轉工具55壓入至既定的深度，因此塑性流動化的塑性流動材Q確實地流入第一空隙部P21而與熱媒體用管216接觸。In the first surface side inflow stirring process, the high-speed rotating inflow stirring rotary tool 55 is pressed from the surface 261 of the second metal member 260, and the inflow stirring rotary tool 55 is viewed in a plane along the second groove 265. The glyph moves. The inflow agitation rotating tool 55 moves so that a portion of the projected portion of the bottom surface 57 (shoulder portion) of the tool body 56 coincides with the first gap portion P21. At this time, the aluminum alloy material of the second metal member 260 around it is plastically fluidized by frictional heat by the pin 58 rotated at a high speed. Since the inflowing stirring rotary tool 55 is pressed to a predetermined depth, the plastic fluidized plastic material Q surely flows into the first gap portion P21 to come into contact with the heat medium tube 216.
在第二表面側流入攪拌工程中，相對於熱媒體用管216的流動方向Y(參照第14圖)使由摩擦攪拌而塑性流動化的塑性流動材Q流入形成於右上側的第二空隙部P22。第二表面側流入攪拌工程除了是在第二空隙部P22進行之外，由於與第一表面側流入攪拌工程相同而省略其說明。而且，在表面側流入攪拌工程結束之後，切削除去形成於第二金屬構件260的表面261的毛邊而使其變得平滑。In the second surface side inflow and agitation process, the plastic flow material Q which is plastically fluidized by friction stir is flown into the second gap portion formed on the upper right side with respect to the flow direction Y of the heat medium tube 216 (see FIG. 14).

Then, after the surface side inflow and agitation process is completed, the burrs formed on the surface 261 of the second metal member 260 are cut and removed to be smoothed.
根據以上說明的傳熱板的製造方法，即使第一凹槽258及第二凹槽265都形成曲面，由第一凹槽258及第二凹槽265形成的空間部K2的高度H形成比熱媒體用管216的外徑大，即使在熱媒體用管216的一部份彎曲的情況下，也容易地進行上述的蓋槽閉塞工程。According to the manufacturing method of the heat transfer plate described above, even if the first groove 258 and the second groove 265 form a curved surface, the height H of the space portion K2 formed by the first groove 258 and the second groove 265 forms a specific heat medium. The outer diameter of the tube 216 is large, and even when a part of the heat medium tube 216 is bent, the above-described lid groove closing process can be easily performed.
又，藉由表面側流入攪拌工程，藉由使塑性流動材Q流入形成於熱媒體用管216的周圍的第一空隙部P21及第二空隙部P22，由於可掩埋該空隙部，而可提高傳熱板251的熱交換效率。In addition, by flowing the plastic flow material Q into the first gap portion P21 and the second gap portion P22 formed around the heat medium tube 216 by the surface side inflow stirring process, the gap portion can be buried, thereby improving The heat exchange efficiency of the heat transfer plate 251.

The groove 335 is provided with the second metal member 333 at the same time.
接著，針對本發明的第十一實施形態做說明。如第26圖所示，第十一實施形態的傳熱板445雖然在第一金屬構件402上形成第一凹槽408，但在第二金屬構件410上不形成第二凹槽的特徵與第十實施形態不同。Next, an eleventh embodiment of the present invention will be described. As shown in FIG. 26, although the heat transfer plate 445 of the eleventh embodiment forms the first groove 408 on the first metal member 402, the feature of the second groove is not formed on the second metal member 410. Ten implementations are different.

The first groove 408 has a U-shaped cross section and is in surface contact with the lower half of the heat medium tube 216. Further, the height of the first groove 408 is formed larger than the outer diameter of the heat medium tube 216.
第二金屬構件410為板狀構件，配置於第一金屬構件402的蓋槽406。第一金屬構件402與第二金屬構件410分別在平接部V21、V22進行摩擦攪拌接合。The second metal member 410 is a plate-shaped member and is disposed in the cover groove 406 of the first metal member 402. The first metal member 402 and the second metal member 410 are friction stir welded at the flat portions V21 and V22, respectively.
藉由流入攪拌工程而使塑性流動材流入形成於熱媒體用管216周圍的第一空隙部P1及第二空隙部P2。即，從第二金屬構件410的表面插入流入攪拌用旋轉工具55，而使第一金屬構件402與第二金屬構件410塑性流動化，使塑性流動材流入第一空隙部P1及第二空隙部P2。在第二金屬構件410的表面形成塑性化區域W23、W24。藉此，可掩埋熱媒體用管216周圍的空隙。又，由於第一凹槽408的高度形成比熱媒體用管216的外徑大，可容易地進行將熱媒體用管216及第二金屬構件410配置於第一金屬構件402的作業。The plastic flow material flows into the first void portion P1 and the second void portion P2 formed around the heat medium tube 216 by flowing into the stirring process. That is, the inflowing agitation rotating tool 55 is inserted from the surface of the second metal member 410, and the first metal member 402 and the second metal member 410 are plastically fluidized, and the plastic flowing material flows into the first gap portion P1 and the second gap portion. P2. Plasticized regions W23, W24 are formed on the surface of the second metal member 410. Thereby, the gap around the heat medium tube 216 can be buried. Moreover, since the height of the first groove 408 is larger than the outer diameter of the heat medium tube 216, the operation of disposing the heat medium tube 216 and the second metal member 410 on the first metal member 402 can be easily performed.
而且，在第十一實施形態中，在流入攪拌工程之際，流入攪拌用旋轉工具55的前端最好設定成到達第一金屬構件402與第二金屬構件410的交界面。藉此，可接合第一金屬構件402與第二金屬構件410之同時，塑性流動材可確實地流入第一空隙部P1及第二空隙部P2。Further, in the eleventh embodiment, it is preferable that the tip end of the inflow stirring rotary tool 55 is set to reach the interface between the first metal member 402 and the second metal member 410 when the stirring process is performed. Thereby, the first metal member 402 and the second metal member 410 can be joined, and the plastic flow material can surely flow into the first gap portion P1 and the second gap portion P2.
