Description

本発明は、熱交換装置に関するものである。   The present invention relates to a heat exchange device.

従来、熱交換装置（例えばインタークーラー）を形成するために、複数の熱交換器（インタークーラーＩ．Ｃ．単体）を、パイプＰを介して直列状に連結したものがある（図９、図１０参照）。
この場合、例えば大型の建設機械等のエンジンに使用されるラジエータには、激しい振動や衝撃等の過酷な使用条件に耐え得るように、またラジエータ損傷時に、損傷部の部分的な交換により、容易に修理し得るように、小型熱交換装置を、直列あるいは並列に連結して形成した複合型熱交換装置がしばしば使用される。
例えば、特許文献１のように、直列に並ぶ上下の熱交換器単体の互いに重合しうる突出部を設けると共に、両突出物の重合面に、両サブタンクを連通するボルトとナットとをもって、両サブタンクを結合し、さらに両サブタンクを、適宜の手段で、両メインタンクと一体をなす補強杆に固定してなるものがある。 Conventionally, in order to form a heat exchange device (for example, an intercooler), a plurality of heat exchangers (intercooler IC) are connected in series via a pipe P (see FIGS. 9 and 10). ).
In this case, for example, a radiator used in an engine such as a large construction machine can easily withstand severe use conditions such as severe vibration and shock, and when the radiator is damaged, it can be easily replaced by partially replacing the damaged part. Therefore, a composite heat exchange device formed by connecting small heat exchange devices in series or in parallel is often used.
For example, as in Patent Document 1, the upper and lower heat exchangers arranged in series are provided with protrusions that can overlap each other, and the overlapping surfaces of both protrusions have bolts and nuts that communicate the two subtanks. In addition, there is a structure in which both sub-tanks are fixed to a reinforcing rod integrated with both main tanks by appropriate means.

実開昭６３−３０７７０号公報Japanese Utility Model Publication No. 63-30770

ところで、インタークーラーの熱交換装置性能指標の一つである過給気の圧力損失は、一般的に次のように分割できるとされている。
ΔＰｇ total＝ΔＰｇ pipe ＋ΔＰｇ tube ＋ΔＰｇ core
｛ただし、ΔＰｇ total：インタークーラー全体の圧力損失，ΔＰｇ pipe：パイプ部圧力損失（拡大収縮、摩擦），ΔＰｇ tube：チューブ入口出口圧力損失（拡大収縮），ΔＰｇ core：コア部損失（チューブ内部摩擦）｝ By the way, it is said that the pressure loss of supercharged air, which is one of the performance indicators of the heat exchanger of the intercooler, can be generally divided as follows.
ΔPg total = ΔPg pipe + ΔPg tube + ΔPg core
{However, ΔPg total: Pressure loss of the entire intercooler, ΔPg pipe: Pipe portion pressure loss (expansion and contraction, friction), ΔPg tube: Tube inlet / outlet pressure loss (expansion and contraction), ΔPg core: Core portion loss (tube internal friction) }

従って、各インタークーラーＩ．Ｃ．を接続する場合、図９のように連結すると、圧力損失を生じるパイプ部ｐ（ΔＰｇ pipe）が３箇所、チューブ入口出口（ΔＰｇ tube）が２箇所、コア部が１箇所であり、単体のインタークーラーＩ．Ｃ．（図１０参照）における圧力損失を生じる箇所として、パイプ部ｐ（ΔＰｇ pipe）が２箇所、チューブ入口出口（ΔＰｇ tube）が１箇所、コア部が１箇所であるから、図９のような直列連結したものは、単体のインタークーラーＩ．Ｃ．よりも全体の圧力損失（ΔＰｇ total）が高くなってしまうことがわかる。
本発明はこのような課題を改善するために提案されたものであって、過給気の圧力損失を低減可能とする一方、連結時の剛性を高めることによって構造の強化を図り、耐振性を向上させるようにした、熱交換装置を提供することを目的とする。 Therefore, each intercooler I.D. C. When connecting as shown in FIG. 9, there are three pipe parts p (ΔPg pipe) that cause pressure loss, two tube inlet / outlet (ΔPg tube), and one core part, and a single intercooler I. C. As shown in FIG. 9, there are two pipe parts p (ΔPg pipe), one tube inlet / outlet (ΔPg tube), and one core part as the places where pressure loss occurs (see FIG. 10). What is connected is a single intercooler I.D. C. It turns out that the whole pressure loss ((DELTA) Pgtotal) will become high.
The present invention has been proposed in order to improve such a problem, and it is possible to reduce the pressure loss of the supercharged air, while at the same time strengthening the structure by increasing the rigidity at the time of connection and improving the vibration resistance. An object of the present invention is to provide a heat exchange device that is improved.

（第１実施形態）
図１、図２に、本発明にかかる熱交換装置１０を模式的に示す。この熱交換装置１０は、インタークーラーであり、複数（ここでは２つ）の熱交換器１０ｕをヘッダタンク１１を介して互いに連結して構成したものである。
熱交換器１０ｕは、実質的に、コア部１２として、流体として冷却水が流通する複数本の断面扁平形状のチューブ１３と、これらチューブ１３間において、チューブ１３の外表面に接合されて空気との伝熱面積を増大させる波状のフィン１４とを備え、それぞれの熱交換器１０ｕを、チューブ１３の長手方向両端側に位置して、各チューブ１３と連通するヘッダタンク１１とから構成されている。 (First embodiment)
1 and 2 schematically show a heat exchange device 10 according to the present invention. This heat exchange device 10 is an intercooler, and is configured by connecting a plurality (here, two) of heat exchangers 10 u to each other via a header tank 11.
The heat exchanger 10u is substantially composed of a plurality of tubes 13 having a flat cross-sectional shape in which cooling water flows as a fluid as the core portion 12, and between these tubes 13 joined to the outer surface of the tube 13 and air. Each of the heat exchangers 10 u is located on both ends of the tubes 13 in the longitudinal direction, and includes a header tank 11 communicating with each tube 13. .

ヘッダタンク１１は、それぞれの熱交換器１０ｕにおける、複数のチューブ１３端部近傍を互いに接合したコアプレート部１１ａを備え、これらコアプレート部１１ａを、互いに所定の密接面積で液密に、例えばろう付けにより固定した合わせ縁部１１ｅを介して連結して構成している。
その場合、それぞれの熱交換器１０ｕは、複数のチューブ１３端部側が、コアプレート部１１ａで構成するヘッダタンク１１内の密閉された空間に開放されている（図３参照）。
なお、これら２つの熱交換器１０ｕで構成される熱交換装置１０では、図中、上部の導入タンク部１５には、冷却水の入口パイプ１６、下部の排出タンク部１７には出口パイプ１８が設けられている。 The header tank 11 includes a core plate portion 11a in which the vicinity of the ends of the plurality of tubes 13 in each heat exchanger 10u are joined to each other, and the core plate portions 11a are liquid-tight, for example, in a predetermined close area. It is configured to be connected through an alignment edge portion 11e fixed by attachment.
In that case, each heat exchanger 10u is open | released by the sealed space in the header tank 11 comprised by the core plate part 11a in the some tube 13 edge part side (refer FIG. 3).
In the heat exchanging device 10 constituted by these two heat exchangers 10u, in the drawing, the inlet tank portion 15 in the upper portion has an inlet pipe 16 for cooling water and the outlet pipe portion 18 in the lower discharge tank portion 17. Is provided.

以上のような接続構成によれば、圧力損失が生じる箇所は、冷却水の入口パイプ１６、出口パイプ１８の２箇所（ΔＰｇ pipe）、コア部１２におけるチューブ１３への入口出口圧力損失として２箇所（ΔＰｇ tube）、コア部１２における圧力損失として１箇所（ΔＰｇ core）となり、少なくとも、図９に示す連結構成のインタークーラーに比較して圧力損失を抑制することができる。   According to the connection configuration as described above, there are two places where the pressure loss occurs as two places (ΔPg pipe) of the cooling water inlet pipe 16 and the outlet pipe 18 and the inlet outlet pressure loss to the tube 13 in the core portion 12. (ΔPg tube), the pressure loss in the core portion 12 is one place (ΔPg core), and at least the pressure loss can be suppressed as compared with the intercooler having the connection configuration shown in FIG.

また、２つの熱交換器１０ｕをヘッダタンク１１を介して結合したことにより、少なくとも、同寸法の単体の熱交換器（インタークーラー）に比較して、２つの熱交換器１０ｕの中間位置にあるヘッダダンク１１結合箇所によって剛性が高くなり、耐振性は向上する。   In addition, since the two heat exchangers 10u are coupled via the header tank 11, the header is located at an intermediate position between the two heat exchangers 10u as compared to at least a single heat exchanger (intercooler) having the same dimensions. Rigidity is increased by the location where the dunk 11 is joined, and vibration resistance is improved.

（第２実施形態）
本発明にかかる熱交換装置１０は、また、図４のように構成することもできる。
この熱交換装置１０では、２つの熱交換器１０ｕを連結する構造として、ヘッダタンク１１内において、隣接する熱交換器１０ｕにおける複数本のチューブ１３間を、互いに流通可能に連結する構成としている。
すなわち、隣接する熱交換器１０ｕにおける複数本のチューブ１３間を、直接、それぞれ連結パイプ１９によって連結する構成としている。なお、チューブ１３内には、図５に示すように、フィンｆが介在されていてもよい。 (Second Embodiment)
The heat exchange device 10 according to the present invention can also be configured as shown in FIG.
In this heat exchange device 10, as a structure for connecting two heat exchangers 10 u, a plurality of tubes 13 in adjacent heat exchangers 10 u are connected to each other so as to be able to circulate in the header tank 11.
That is, the plurality of tubes 13 in the adjacent heat exchanger 10 u are directly connected by the connection pipe 19. Note that fins f may be interposed in the tube 13 as shown in FIG.

これにより、チューブ１３同士を直接的に連結したことにより、第１実施形態で示した、圧力損失より、コア部１２におけるチューブ１３への入口出口圧力損失が１箇所（ΔＰｇ tube）となり、一層、圧力損失を抑えることができる。
なお、チューブ１３内にフィンｆを介在する構成とすれば、圧力損失という点では不利になるものの、チューブ１３内を流体がフィンｆに接触しながら流通するため、熱拡散の効果を促進させることができる。 Thereby, by connecting the tubes 13 directly, the pressure loss shown in the first embodiment, the pressure loss at the inlet to the tube 13 in the core portion 12 becomes one place (ΔPg tube). Pressure loss can be suppressed.
In addition, although it will be disadvantageous in the point of pressure loss if it is set as the structure which interposes the fin f in the tube 13, since the fluid distribute | circulates the tube 13 in contact with the fin f, the effect of thermal diffusion is promoted. Can do.

（第３実施形態）
本発明にかかる熱交換装置１０は、また、図６のように構成することもできる。
この場合の熱交換装置１０では、隣接する熱交換器１０ｕ同士を連結するヘッダタンク１１において、車両本体における適宜な固定部材に固定している。
この場合、双方の熱交換器１０ｕにおけるヘッダタンク１１の互いの当接面である、合わせ縁部１１ｅ間に、支持補助部材２０を第１の締付けボルト２１により挟持し、この支持補助部材２０に、車体本体の適宜な固定部材２２に対して第２の締付けボルト２３により固定するようにしている。 (Third embodiment)
The heat exchanging device 10 according to the present invention can also be configured as shown in FIG.
In the heat exchange device 10 in this case, the header tank 11 that connects the adjacent heat exchangers 10u is fixed to an appropriate fixing member in the vehicle body.
In this case, the supporting auxiliary member 20 is sandwiched between the mating edge portions 11e, which are the contact surfaces of the header tanks 11 in both heat exchangers 10u, by the first tightening bolts 21, and the supporting auxiliary member 20 The second fastening bolt 23 fixes the vehicle body to an appropriate fixing member 22.

以上のような熱交換装置１０によれば、熱交換器１０ｕ同士をヘッダタンク１１を介して連結したことにより剛性、強度が向上したことから、このヘッダタンク１１を利用して車体側に固定することにより、車体から伝わる運転時の振動や衝撃などにも、充分に耐え得る強度を確保することができる。   According to the heat exchange device 10 as described above, since the rigidity and strength are improved by connecting the heat exchangers 10u via the header tank 11, the header tank 11 is used to fix the heat exchanger 10u to the vehicle body side. As a result, it is possible to secure a sufficient strength to withstand vibrations and shocks during driving transmitted from the vehicle body.

（第４実施形態）
本発明にかかる熱交換装置１０は、また、図７，８のように構成することもできる。
前述したように、第１〜第３実施形態は、熱交換器１０ｕを２基、連結した例を挙げたが、勿論、熱交換器１０ｕを３基、結合するようにしてもよい。
この場合の圧力損失が生じる箇所は、冷却水の入口パイプ１６、出口パイプ１８の２箇所（ΔＰｇ pipe）、コア部１２におけるチューブ１３への入口出口圧力損失として３箇所（ΔＰｇ tube）、コア部１２における圧力損失として１箇所（ΔＰｇ core）となる。 (Fourth embodiment)
The heat exchanging device 10 according to the present invention can also be configured as shown in FIGS.
As described above, in the first to third embodiments, an example in which two heat exchangers 10u are connected has been described. Of course, three heat exchangers 10u may be combined.
In this case, the pressure loss occurs at two locations (ΔPg pipe) of the cooling water inlet pipe 16 and the outlet pipe 18, and at three locations (ΔPg tube) as the inlet / outlet pressure loss to the tube 13 in the core portion 12. The pressure loss at 12 is one place (ΔPg core).

このように、本発明は、これまでのように、熱交換器１０ｕをつなぐパイプをなくし、熱交換器１０ｕ同士をヘッダタンク１１を介して連結したことにより、剛性、強度が向上すると共に、熱交換器１０ｕをつなぐパイプをなくしたことから、圧力損失を減じることができ、３基、熱交換器１０ｕを連結しても、高効率を確保することができる。   As described above, the present invention eliminates the pipe connecting the heat exchangers 10u and connects the heat exchangers 10u to each other via the header tank 11 so that the rigidity and the strength are improved. Since the pipe connecting the exchanger 10u is eliminated, pressure loss can be reduced, and high efficiency can be ensured even if three heat exchangers 10u are connected.
