上記1)の作動流体注入装置によれば、中空回路基板を、その注入口が注入本体の注出口に合致するように、注入本体の接触面に接触させ、この状態で固定手段により固定するだけで、作動流体供給装置から注入本体の作動流体通路を通して中空回路基板の中空回路内に作動流体を注入することができる。そして、中空回路基板の注入口は、接合する前の金属板を所定形状に打ち抜く際などに同時に形成することができるので、製造された中空回路基板に加工を施す必要はなく、工数が少なくなって加工コストが安くなる。また、中空回路基板の注入口が若干位置ずれしていたとしても、中空回路基板における注入口が形成された金属板の外面と、注入本体の接触面との間のシール性が低下することはなく、作動流体の漏れが防止される。 According to the working fluid injection device of the above 1), the hollow circuit board is brought into contact with the contact surface of the injection body so that the injection port thereof coincides with the spout of the injection body, and in this state, only fixed by the fixing means. Thus, the working fluid can be injected from the working fluid supply device into the hollow circuit of the hollow circuit board through the working fluid passage of the injection body. And since the injection port of a hollow circuit board can be formed simultaneously when the metal plate before joining is punched into a predetermined shape, it is not necessary to process the manufactured hollow circuit board, and man-hours are reduced. This reduces the processing cost. In addition, even if the injection port of the hollow circuit board is slightly displaced, the sealing performance between the outer surface of the metal plate in which the injection port is formed in the hollow circuit board and the contact surface of the injection body is reduced. And leakage of the working fluid is prevented.
上記2)の作動流体注入装置によれば、注入本体の継手部を利用して作動流体供給装置を接続することができる。 According to the working fluid injection device of 2) above, the working fluid supply device can be connected using the joint portion of the injection main body.
上記3)の作動流体注入装置を、たとえば中空回路基板からなるコンテナの中空回路内へのヒートパイプ用作動流体の注入に使用する場合、中空回路基板の中空回路内に所定量のヒートパイプ用作動流体を注入した後、中空回路基板を加熱して中空回路内の非凝縮性ガスを注入本体の作動流体通路を通して排出するが、この場合であっても、作動流体流出防止用小径部の働きにより、ヒートパイプ用作動流体の流出が防止され、その結果中空回路内へのヒートパイプ用作動流体の注入量を精度良く管理することができる。すなわち、ヒートパイプ用作動流体を中空回路内に注入した後中空回路基板を加熱すると、ヒートパイプ用作動流体が突沸し、作動流体通路を通して外部に流出することがある。しかしながら、注入本体の作動流体通路に作動流体流出防止用小径部が設けられていると、上述したヒートパイプ用作動流体の外部への流出を防止することができる。 When the working fluid injection device of 3) above is used, for example, to inject a working fluid for a heat pipe into a hollow circuit of a container made of a hollow circuit substrate, a predetermined amount of heat pipe operation is inserted into the hollow circuit of the hollow circuit substrate. After the fluid is injected, the hollow circuit board is heated to discharge the non-condensable gas in the hollow circuit through the working fluid passage of the injection body. The outflow of the working fluid for the heat pipe is prevented, and as a result, the injection amount of the working fluid for the heat pipe into the hollow circuit can be managed with high accuracy. That is, when the hollow circuit board is heated after injecting the heat pipe working fluid into the hollow circuit, the heat pipe working fluid may bump up and flow out to the outside through the working fluid passage. However, if the working fluid outflow prevention small-diameter portion is provided in the working fluid passage of the injection main body, the above-described outflow of the heat pipe working fluid can be prevented.
上記4)の作動流体注入装置によれば、上記3)で述べた効果が顕著なものになる。 According to the working fluid injection device of the above 4), the effect described in the above 3) becomes remarkable.
上記5)の作動流体注入装置によれば、ヒートパイプ用作動流体を中空回路内に注入した後中空回路基板を加熱した際に、ヒートパイプ用作動流体が突沸して注入本体の作動流体通路内に流出したとしても、作動流体流出防止用小径部を除いた部分で凝縮し、中空回路基板の中空回路内に戻る。 According to the working fluid injection device of the above 5), when the heat circuit for the heat pipe is injected into the hollow circuit and the hollow circuit board is heated, the working fluid for the heat pipe bumps into the working fluid passage of the injection main body. Even if it flows out into the hollow circuit board, it is condensed at a portion other than the small diameter portion for preventing working fluid outflow, and returns to the hollow circuit of the hollow circuit board.
上記6)の作動流体注入装置によれば、ヒートパイプ用作動流体を中空回路内に注入した後中空回路基板を加熱した際に、ヒートパイプ用作動流体が突沸して注入本体の作動流体通路内に流入したとしても、外部への流出量をできるだけ少なくすることができる。 According to the working fluid injection device of the above 6), when the hollow circuit board is heated after injecting the working fluid for the heat pipe into the hollow circuit, the working fluid for the heat pipe bumps into the working fluid passage of the injection body. Even if it flows in, the outflow amount to the outside can be reduced as much as possible.
上記7)の作動流体注入装置によれば、固定手段の構成が比較的簡単になる。 According to the working fluid injection device of the above 7), the structure of the fixing means becomes relatively simple.
上記8)の作動流体注入装置によれば、注入本体における接触面が形成された部分と、クランプ部材の挟着部とにより確実に中空回路基板を固定することができる。 According to the working fluid injection device of the above 8), the hollow circuit substrate can be reliably fixed by the portion of the injection body where the contact surface is formed and the clamping portion of the clamp member.
上記9)および10)の作動流体注入装置によれば、中空回路基板の厚さにばらつきが存在している場合にも、中空回路基板の注入口が形成された面と、クランプ部材により注入本体の接触面全体に均一に押し付けることができ、シール性が向上して作動流体の漏れを防止することが可能になる。 According to the working fluid injection device of the above 9) and 10), even when there is variation in the thickness of the hollow circuit board, the injection body is formed by the surface on which the injection port of the hollow circuit board is formed and the clamp member It is possible to evenly press the entire contact surface, improving the sealing performance and preventing the working fluid from leaking.
上記11)〜13)の作動流体注入装置によれば、注入本体の注入口の位置を、簡単に中空回路基板の注出口に合わせることができる。 According to the above working fluid injection devices 11) to 13), the position of the injection port of the injection main body can be easily adjusted to the spout of the hollow circuit board.

作動流体注入装置(10)を用いての中空回路基板(1)の中空回路(4)内へのヒートパイプ用作動流体の注入は次のようにして行われる。 Injection of the working fluid for the heat pipe into the hollow circuit (4) of the hollow circuit board (1) using the working fluid injection device (10) is performed as follows.
まず、偏心レバー(15)を固定解除位置に切り換えておき（図３参照）、中空回路基板(1)の上方突出部(5)を、その平坦面(5a)が後側を向くように、左右両側縁部を位置決め用案内部(26)により案内して注入本体(11)の両ブラケット(25)間に差し込み、その先端部を位置決め用受け部(24)に当接させる。これにより、中空回路基板(1)の位置が、注入口(7)が注出口(18)と合致するように決められる。ついで、偏心レバー(15)を図３の時計方向に回動させて固定位置に切換え、作用部(16)の部分円筒面(16a)によりクランプ部材(13)を圧縮コイルバネ(41)の付勢力に抗して後方に押圧し、クランプ部材(13)を図３の反時計方向に回動させ、クランプ部材(13)の挟着部(14)と注入本体(11)における接触面(12)が形成された下端部とにより上方突出部(5)を挟着して、中空回路基板(1)を、その注入口(7)と注入本体(11)の注出口(18)とが合致するように固定する（図４参照）。このとき、中空回路基板(1)の厚さが寸法公差の分だけばらついていたとしても、支持軸(37)が支持軸挿通用長穴(38)内を移動することにより、注入本体(11)の接触面(12)全体に、中空回路基板(1)の上方突出部(5)の平坦面(5a)が均一に押し付けられる。そして、Ｏリング(23)により中空回路基板(1)の上方突出部(5)の平坦面(5a)における注入口(7)の周囲の部分と、注入本体(11)の接触面(12)における注出口(18)の周囲の部分との間が密封される。 First, the eccentric lever (15) is switched to the unlocking position (see FIG. 3), and the upper protrusion (5) of the hollow circuit board (1) is placed so that the flat surface (5a) faces the rear side. The left and right side edge portions are guided by the positioning guide portion (26) and inserted between the brackets (25) of the injection body (11), and the tip portions thereof are brought into contact with the positioning receiving portion (24). Thereby, the position of the hollow circuit board (1) is determined so that the inlet (7) matches the spout (18). Next, the eccentric lever (15) is rotated clockwise in FIG. 3 to switch to the fixed position, and the clamping member (13) is biased by the compression coil spring (41) by the partial cylindrical surface (16a) of the action portion (16). 3 and the clamp member (13) is rotated counterclockwise in FIG. 3 so that the clamping portion (14) of the clamp member (13) and the contact surface (12) of the injection body (11) The upper projecting portion (5) is sandwiched by the lower end portion formed with the hollow circuit board (1), and the injection port (7) and the spout (18) of the injection main body (11) match. (See FIG. 4). At this time, even if the thickness of the hollow circuit board (1) varies by the dimensional tolerance, the support shaft (37) moves in the support shaft insertion slot (38), so that the injection body (11 The flat surface (5a) of the upper projecting portion (5) of the hollow circuit board (1) is uniformly pressed against the entire contact surface (12) of Then, a portion around the injection port (7) in the flat surface (5a) of the upper protrusion (5) of the hollow circuit board (1) by the O-ring (23) and the contact surface (12) of the injection body (11) The space around the spout (18) is sealed.
ついで、継手部材(27)に図示しない作動流体供給装置を接続する。作動流体供給装置には弁体押し下げピンが設けられており、この弁体押し下げピンにより弁体(32)が圧縮コイルバネ(36)の付勢力に抗して押し下げられ、閉止弁(29)が開となる。ついで、作動流体供給装置により、継手部材(27)内、注入本体(11)の作動流体通路(17)および中空回路基板(1)の作動流体注入用膨出部(6)を通して中空回路(4)内に所要量の作動流体を注入する。 Next, a working fluid supply device (not shown) is connected to the joint member (27). The working fluid supply device is provided with a valve body push-down pin, by which the valve body (32) is pushed down against the urging force of the compression coil spring (36), and the closing valve (29) is opened. It becomes. Subsequently, the working fluid supply device causes the hollow circuit (4) to pass through the joint member (27), the working fluid passage (17) of the injection body (11), and the working fluid injection bulge portion (6) of the hollow circuit board (1). ) Inject a required amount of working fluid into the inside.
ついで、注入本体(11)の継手部材(27)から作動流体供給装置を外す。すると、圧縮コイルバネ(36)により弁体(32)およびシール部材(41)が弁座(35)に押し付けられて閉止弁(29)が閉となる。ついで、中空回路基板(1)の下部を、たとえば湯に漬けて加熱する。すると、中空回路(4)内のヒートパイプ用作動流体が蒸発してガス状作動流体となり、これによって作動流体に溶存しかつ中空回路(4)内に残留していたＮ２、ＣＯ２、Ｏ２などの非凝縮性ガスが、注入本体(11)の作動流体通路(17)内に押し込まれてここに溜められる。このとき、中空回路(4)内のヒートパイプ用作動流体が突沸することがあるが、突沸した作動流体は、注入本体(11)の作動流体流出防止用小径部(21)内には流入しにくく、作動流体通路(17)における作動流体流出防止用小径部(21)よりも下方の部分に溜められる。 Next, the working fluid supply device is removed from the joint member (27) of the injection body (11). Then, the valve body (32) and the seal member (41) are pressed against the valve seat (35) by the compression coil spring (36), and the closing valve (29) is closed. Next, the lower part of the hollow circuit board (1) is heated in, for example, hot water. Then, the working fluid for the heat pipe in the hollow circuit (4) evaporates to become a gaseous working fluid, whereby N 2 , CO 2 , O dissolved in the working fluid and remaining in the hollow circuit (4). A non-condensable gas such as 2 is pushed into the working fluid passageway (17) of the injection body (11) and stored there. At this time, the heat pipe working fluid in the hollow circuit (4) may bump, but the bumped working fluid flows into the working fluid outflow prevention small diameter portion (21) of the injection body (11). The working fluid passage (17) is stored in a portion below the working fluid outflow prevention small diameter portion (21).
中空回路基板(1)を一定時間加熱した後、図示しない弁体押し下げロッドにより、弁体(32)を圧縮コイルバネ(36)の付勢力に抗して押し下げ、非凝縮性ガスを排出する。このとき、作動流体流出防止用小径部(21)の働きにより突沸した作動流体の外部への漏れが防止される。また、作動流体通路(17)における作動流体流出防止用小径部(21)よりも下方の部分に溜められた作動流体は凝縮し、注出口(18)、注入口(7)および作動流体注入用膨出部(6)を通って中空回路基板(1)の中空回路(4)内に戻される。 After the hollow circuit board (1) is heated for a certain time, the valve body (32) is pushed down against the urging force of the compression coil spring (36) by a valve body push-down rod (not shown), and the non-condensable gas is discharged. At this time, the working fluid outflow prevention small-diameter portion (21) prevents the working fluid boiled off from leaking to the outside. In addition, the working fluid accumulated in the portion of the working fluid passage (17) below the small diameter portion (21) for preventing working fluid outflow is condensed, and the outlet (18), inlet (7), and working fluid injection It returns to the hollow circuit (4) of the hollow circuit board (1) through the bulging portion (6).
ついで、注入本体(11)とクランプ部材(13)とにより挟着されている部分の下方において、中空回路基板(1)の作動流体注入用膨出部(6)全体を圧潰し、さらに上方突出部(5)を切断することにより、注入本体(11)の作動流体通路(17)内に残存している非凝縮性ガスが中空回路(4)内へ逆流しないようにしておいてから、偏心レバー(15)を固定解除位置に切換え、作動流体注入装置(10)を取り外す。最後に、中空回路基板(1)に残存した圧潰部の上端を溶接し、中空回路(4)を完全に密閉する。こうして、中空回路(4)内に作動流体が注入されて凝縮部および蒸発部を有するヒートパイプ部となり、平板状ヒートパイプが製造される。 Next, below the portion sandwiched between the injection main body (11) and the clamp member (13), the entire bulging portion (6) for injecting the working fluid of the hollow circuit board (1) is crushed and further protrudes upward. By cutting the part (5), the non-condensable gas remaining in the working fluid passage (17) of the injection body (11) is prevented from flowing back into the hollow circuit (4). Switch the lever (15) to the unlocking position and remove the working fluid injection device (10). Finally, the upper end of the crushing portion remaining on the hollow circuit board (1) is welded to completely seal the hollow circuit (4). Thus, the working fluid is injected into the hollow circuit (4) to form a heat pipe portion having a condensing portion and an evaporation portion, and a flat plate heat pipe is manufactured.
平板状ヒートパイプは、中空回路基板(1)の少なくとも一面におけるヒートパイプ部の凝縮部と対応する部分に、放熱フィンが取り付けられ、たとえば放熱装置として用いられる。放熱装置は、平板状ヒートパイプの中空回路基板のいずれかの面におけるヒートパイプ部の蒸発部と対応する部分に、発熱電子部品が熱的に接触させられた状態で産業機械、たとえばＣＮＣ（コンピュータ数値制御）工作機械に用いられる。ＣＮＣ工作機械の発熱電子部品は、たとえば制御装置の発熱電子部品である。 The flat heat pipe is attached to a portion corresponding to the condensing portion of the heat pipe portion on at least one surface of the hollow circuit board (1), and is used as a heat radiating device, for example. The heat dissipating device is an industrial machine such as a CNC (computer) with a heat generating electronic component in thermal contact with a portion corresponding to the evaporation portion of the heat pipe portion on either side of the hollow circuit board of the flat plate heat pipe. (Numerical control) Used for machine tools. The heat generating electronic component of the CNC machine tool is, for example, a heat generating electronic component of the control device.
