Description

本発明は、一例としてエンジン冷却水を冷却する大型の熱交換器に最適なものであって、その冷却水が一対のタンク間を蛇行状に流通するものに関する。   The present invention relates to a large heat exchanger that cools engine cooling water as an example, and relates to the cooling water that circulates between a pair of tanks in a meandering manner.

建設機械用の熱交換器の如く、大型で熱交換量の大きなものであって、エンジン冷却水をＵ字状にまたは、蛇行状に流通させるものが知られている。
下記特許文献１に記載の熱交換器は、コアの上下に一対のタンクを設け、上側のタンクはその長手方向中央に仕切部を配置することにより、冷却水をＵ字状に流通させるものが提案されている。
この熱交換器は、冷却水の流路長が長くなり、熱交換を促進させることができる。 As a heat exchanger for a construction machine, a large heat exchanger having a large heat exchanging amount and circulating engine cooling water in a U shape or a meandering shape is known.
In the heat exchanger described in Patent Document 1 below, a pair of tanks are provided at the top and bottom of the core, and the upper tank has a partition portion disposed at the center in the longitudinal direction, thereby circulating cooling water in a U-shape. Proposed.
In this heat exchanger, the flow path length of the cooling water becomes long, and heat exchange can be promoted.

特開昭５９−１０４０９６号公報JP 59-104096 Gazette

上側タンク内に仕切を設けて、流体を２パス型に流通させたものは、コアの一方の半分側を流通する温度と他方側を流通する流体の温度とが異なる。そのため、仕切を挟んで隣接するチューブ間に伝熱が生じ、その境界部において熱交換が低下する。それと共に、隣接するチューブ間に温度差が生じ、熱歪みを生じる。
そこで本発明は、複パス型の熱交換器においてコアの一方側から他方側に伝熱の生じ難いものを提供することを課題とする。 In the case where a partition is provided in the upper tank and the fluid is circulated in a two-pass type, the temperature at which one half of the core circulates is different from the temperature of the fluid at the other side. Therefore, heat transfer occurs between adjacent tubes across the partition, and heat exchange is reduced at the boundary portion. At the same time, a temperature difference is generated between adjacent tubes, and thermal distortion occurs.
Then, this invention makes it a subject to provide the thing which does not produce heat transfer easily from the one side of a core to the other side in a multipass type heat exchanger.

次に、図面に基づいて本発明の実施の形態につき説明する。   Next, embodiments of the present invention will be described with reference to the drawings.

図１は本発明の第１実施例の縦断面図であり、図２はそのII−II線断面図である。
また、図３はそれに用いるシール１１の平面および、断面図である。
これは一例として、大型の２パス型のエンジン冷却水冷却用の熱交換器である。
この熱交換器は、偏平チューブ１とフィン２とを交互に並列して、コア３を形成する。そしてコア３の上下両端に一対のタンク４，５が配置されている。各タンク４，５は細長い樹脂製のタンク本体４ａ、５ａの夫々の開口部をチューブプレート４ｂ、５ｂにより閉塞する。 FIG. 1 is a longitudinal sectional view of a first embodiment of the present invention, and FIG. 2 is a sectional view taken along line II-II.
FIG. 3 is a plan view and a sectional view of the seal 11 used therefor.
As an example, this is a heat exchanger for cooling a large two-pass type engine coolant.
In this heat exchanger, the flat tubes 1 and the fins 2 are alternately arranged in parallel to form the core 3. A pair of tanks 4 and 5 are arranged at both upper and lower ends of the core 3. Each of the tanks 4 and 5 closes the respective opening portions of the elongated resin tank bodies 4a and 5a by the tube plates 4b and 5b.

この例では、上側のタンク本体４ａはその中間部に一対の仕切板８が一体に形成されている。一対の仕切板８の間隔は、偏平チューブ１の並列した間隔の２ピッチ分に形成されている。タンク４のチューブプレート４ｂには、等間隔に偏平孔が並列し、各偏平孔に偏平チューブ１の端部が挿通されている。
このチューブプレート４ｂとタンク本体４ａとの間には、図３に示すシール１１が介装される。このシール１１は、タンク本体４ａの外周に整合する環状部１１ｂと、仕切板８に整合する架橋部１１ａとが一体に形成されている。なお、シール１１の断面形状は、円形、楕円形、方形のいずれでもよい。シール１１は予めタンク本体４ａに接着しておくことができる。そしてシール１１を介して、タンク本体４ａをチューブプレート４ｂに圧接して、タンク本体４ａの外周に予め突設された図示しない爪部を折り曲げてカシメることにより、タンク４を形成できる。 In this example, the upper tank main body 4a is integrally formed with a pair of partition plates 8 at an intermediate portion thereof. The interval between the pair of partition plates 8 is formed by two pitches of the parallel interval of the flat tubes 1. Flat holes are arranged in parallel in the tube plate 4b of the tank 4 at equal intervals, and the ends of the flat tubes 1 are inserted into the flat holes.
A seal 11 shown in FIG. 3 is interposed between the tube plate 4b and the tank body 4a. In the seal 11, an annular portion 11 b that matches the outer periphery of the tank body 4 a and a bridging portion 11 a that matches the partition plate 8 are integrally formed. The cross-sectional shape of the seal 11 may be any of a circle, an ellipse, and a square. The seal 11 can be bonded to the tank body 4a in advance. Then, the tank 4 can be formed by pressing the tank body 4a against the tube plate 4b through the seal 11 and bending and crimping a claw portion (not shown) protruding in advance on the outer periphery of the tank body 4a.

次に、この例では下側のタンク本体５ａには、その長手方向の中間部に橋部１０が、図１、図２に記載の如く、一体に形成されている。その橋部１０はタンク本体５ａの開口近くに、一対の仕切用チューブ６の端に対向して、それを覆うように配置され、その両側に脚部１０ａがチューブプレート５ｂ側に曲折されている。その橋部１０の図において下面側は、タンク５内の被冷却媒体１４の流通方向に下方へ下がる傾斜面を有する。また、そのタンク５の底側は貫通部９であり、そこを被冷却媒体１４が流通できる。そして、タンク本体５ａとチューブプレート５ｂとの間に、図３に示すシール１１が介装される。そのシール１１の架橋部１１ａは、橋部１０の脚部１０ａに整合する。そして、下側のタンク本体タンク５ａとチューブプレート５ｂとの間が、上側タンク４と同様にカシメにより固定されてタンク５を形成する。   Next, in this example, a bridge portion 10 is integrally formed on the lower tank body 5a at the middle portion in the longitudinal direction as shown in FIGS. The bridge portion 10 is disposed near the opening of the tank body 5a so as to face and cover the ends of the pair of partitioning tubes 6, and the leg portions 10a are bent to the tube plate 5b side on both sides thereof. . In the drawing of the bridge portion 10, the lower surface side has an inclined surface that falls downward in the flow direction of the medium to be cooled 14 in the tank 5. Further, the bottom side of the tank 5 is a through portion 9 through which the medium 14 to be cooled can flow. A seal 11 shown in FIG. 3 is interposed between the tank body 5a and the tube plate 5b. The bridging portion 11 a of the seal 11 is aligned with the leg portion 10 a of the bridge portion 10. Then, the lower tank body tank 5 a and the tube plate 5 b are fixed by caulking similarly to the upper tank 4 to form the tank 5.

そして、上側のタンク４のタンク本体４ａに設けた入口１２から被冷却媒体１４として、エンジン冷却水がタンク４の左半分に流入し、それがコアの左半分の各偏平チューブ１を流通して下側タンク５に達し、そのタンク５内を左方から右方に移動して右半分の各偏平チューブ１内を上昇し、右半分のタンク４から出口１３を介して外部に流出する。そして各偏平チューブ１及びフィン２の外面に、紙面の表面側から裏面側方向に冷却風が流通し、それと冷却水の被冷却媒体１４との間に熱交換が行われる。このとき、中央に位置する一対の仕切用チューブ６は、その両端が閉塞されているため、そこには被冷却媒体１４は流通しない。そのため。コア３において一対の仕切用チューブ６が左右のコア部の断熱部を形成する。
また、上側のタンク４においては一対の仕切板８及びシール１１がタンク４内の断熱層を形成する。そして、一対の仕切板８はタンク４を二重に仕切ると共に、それがタンクの耐圧性を向上させる。 Then, the engine coolant flows into the left half of the tank 4 as the medium 14 to be cooled from the inlet 12 provided in the tank body 4a of the upper tank 4 and flows through each of the flat tubes 1 in the left half of the core. It reaches the lower tank 5, moves from the left to the right in the tank 5, rises in each flat tube 1 in the right half, and flows out from the right half tank 4 through the outlet 13. Then, cooling air flows through the outer surfaces of the flat tubes 1 and the fins 2 from the front surface side to the back surface side, and heat exchange is performed between the cooling air and the cooling medium 14. At this time, since the both ends of the pair of partitioning tubes 6 positioned at the center are closed, the medium 14 to be cooled does not flow there. for that reason. In the core 3, the pair of partitioning tubes 6 form the heat insulating portions of the left and right core portions.
In the upper tank 4, the pair of partition plates 8 and the seal 11 form a heat insulating layer in the tank 4. The pair of partition plates 8 partitions the tank 4 in a double manner, which improves the pressure resistance of the tank.

上記の例では、下側のタンク本体５ａの橋部１０の下面側を、下流側に下方に下がる傾斜としたが、それを図４に示すように、チューブプレート５ｂの平面に平行に配置しても良い。また、シール１１は、その環状部１１ａと架橋部１１ｂとを一体に形成したが、両者を別体に形成してもよい。また、この例では、上側のタンク４のシール１１と、下側のタンク５のシール１１を同一形状にしたが、それらの形状を異ならせてもよい。   In the above example, the lower surface side of the bridge portion 10 of the lower tank body 5a is inclined downward to the downstream side. However, as shown in FIG. 4, it is arranged parallel to the plane of the tube plate 5b. May be. Moreover, although the seal | sticker 11 integrally formed the cyclic | annular part 11a and the bridge | crosslinking part 11b, you may form both separately. In this example, the seal 11 of the upper tank 4 and the seal 11 of the lower tank 5 have the same shape. However, the shapes may be different.

（他の実施の形態）
上記実施例では２パス型の熱交換器について述べたが、冷却水を蛇行状に流通させる多パス型熱交換器とすることもできる。その場合、下側のタンク５にも一対ずつの仕切板８が設けられる。この熱交換器をインタークーラその他の用途の熱交換器として使用することもできる。 (Other embodiments)
Although the two-pass heat exchanger has been described in the above embodiment, a multi-pass heat exchanger that circulates cooling water in a meandering manner may be used. In that case, a pair of partition plates 8 is also provided in the lower tank 5. This heat exchanger can also be used as a heat exchanger for intercoolers and other applications.
