ところが、最近騒音を防止するために、環状の熱交換体

いる。In the figure, 1 to 4 are fan-shaped columnar tank chambers, 5,
6 are tank chambers 1, 4, respectively. Partition wall separating tank chambers 2 and 3, 7 and 8 are artificial pipes installed in tank chambers 1 and 2, respectively, 9 and 10 are outlet pipes installed in tank chambers 3 and 4, respectively, and 11 is the upper part of tank chamber 1. The caps 12.13 provided on the tank chambers 1, 3. Tank room 2,
14 is a plate fin attached to the annular tube 12.13, and the plate fin 14 is provided radially, and the annular tube 12.13 and the plate fin 14 each form an annular heat exchanger. 15.16, the heat exchangers 15.16 are arranged in the axial direction.

１７．１８はボルト１９によってタンク室１〜４に取付
けられた側板、２０は側板１７を貫通した軸で、軸２０
は駆動源（図示せず）に接続されている。17 and 18 are side plates attached to tank chambers 1 to 4 by bolts 19; 20 is a shaft passing through the side plate 17;
is connected to a driving source (not shown).

２１は側板１７に固定されたシール、２２は軸２０に取
付けられた遠心ファンで、遠心ファン２２は熱交換体１
５．１６内に位置している。21 is a seal fixed to the side plate 17, 22 is a centrifugal fan attached to the shaft 20, and the centrifugal fan 22 is connected to the heat exchanger 1.
It is located within 5.16.

２３は側板１８に取付けられたベルマウスである。23 is a bell mouth attached to the side plate 18.

フィン１４を介して放出される。In this annular heat exchanger, when a centrifugal fan 22 is operated via a shaft 20 and two types of fluids to be cooled are supplied into tank chambers 1 and 2 from inlet pipes 7 and 8, respectively, the fluids to be cooled are annularly shaped. Tank chambers 3, 4 via capillary tubes 12.13
However, the heat contained in the fluid to be cooled is released through the plate fins 14.

ところで、遠心ファン２２を作動すると、冷却風がベル
マウス２３から吸込まれたのち、直角に曲げられて熱交
換体１５．１６を通過するから、側板１８側を通過する
冷却風の風速が側板１７側を通過する冷却風の風速より
も小さくなり、熱交換体１５．１６それぞれを通過する
冷却風の風速が異なるので、冷却効率にバラツキが生ず
る。By the way, when the centrifugal fan 22 is activated, the cooling air is sucked in from the bell mouth 23 and then bent at right angles and passes through the heat exchangers 15 and 16. Since the speed of the cooling air passing through the heat exchangers 15 and 16 is lower than that of the cooling air passing through the heat exchanger 15 and 16, variations occur in the cooling efficiency.

また、熱交換体１５゜１６それぞれを通過する風量は、
ベルマウス２３から吸込まれた全風量ではなく、ベルマ
ウス２３から吸込まれた空気の一部が熱交換体１５を通
過し、他の一部が熱交換体１６を通過するので、各熱交
換体１５．１６の放熱効率が低い。In addition, the air volume passing through each of the heat exchangers 15° and 16 is:
Rather than the total amount of air taken in from the bell mouth 23, a part of the air taken in from the bell mouth 23 passes through the heat exchanger 15, and the other part passes through the heat exchanger 16, so each heat exchanger 15.16 heat dissipation efficiency is low.

さらに、熱交換体を３個以上有する環状熱交換体におい
ては、中央部の熱交換体の入口管、出口管を軸２０と平
行に設けることができない。Furthermore, in an annular heat exchanger having three or more heat exchangers, the inlet pipe and outlet pipe of the central heat exchanger cannot be provided parallel to the axis 20.

そして、中央部の熱交換体の入口管、出口管を軸２０と
平行に設けるには、中央部の熱交換体のタンク室のみを
突出させるか、または入口管、出口管を９０°曲げなけ
ればならず、この場合には環状熱交換器の最大外径が大
きくなってしまう。In order to install the inlet and outlet pipes of the central heat exchanger parallel to the axis 20, either only the tank chamber of the central heat exchanger needs to protrude, or the inlet and outlet pipes must be bent by 90 degrees. Naturally, in this case, the maximum outer diameter of the annular heat exchanger becomes large.

この考案は上述の問題点を解決するためになされたもの

あってもよい。Further, in the above-described embodiment, the heat exchange body is composed of thin tubes and plate fins, but the heat exchange body may be composed of thin tubes and corrugated fins, or other types of heat exchange bodies may be used.

また、被冷却流体の流れる方向は、上述実施例に限定さ
れない。Furthermore, the direction in which the fluid to be cooled flows is not limited to the above embodiment.

さらに、上述実施例においては、片吸込式の遠心ファン

能であり、片吸込遠心ファンを用いる場合に、軸側から
空気を吸込んでもよい。Furthermore, in the above embodiment, a single suction type centrifugal fan was used, but a double suction type centrifugal fan may be used, and an axial fan or other type of fan may also be used. When using a suction centrifugal fan, air may be sucked in from the shaft side.

また、上述実施例においては、ファンを外部支持、外部
駆動としているが、ファン軸の軸受（片持または両持）
を側板に取付けることも可能であり、油圧モータ。In addition, in the above embodiment, the fan is externally supported and externally driven, but the fan shaft bearing (cantilevered or double-sided)
It is also possible to mount the hydraulic motor on the side plate.

電動モータ等のファン駆動源を側板に取付けることもで
きる。A fan drive source such as an electric motor can also be attached to the side plate.

さらに、上述実施例においては冷却風を中心から半径方
向外側へ向けて送ったが、冷却風を反対方向に送っても
よい。Further, in the above embodiment, the cooling air was sent radially outward from the center, but the cooling air may be sent in the opposite direction.

以上説明したように、この考案に係る環状熱交換器にお
いては、熱交換体が同心状に配置されているから、軸方
向で風速が異なったとしても、各熱交換体を冷却風が一
様に通過するから、各被冷却流体の冷却効率にバラツキ
が生ずることがない。As explained above, in the annular heat exchanger according to this invention, since the heat exchangers are arranged concentrically, even if the wind speed differs in the axial direction, the cooling air flows uniformly through each heat exchanger. Therefore, there is no variation in the cooling efficiency of each fluid to be cooled.

また、各熱交換体をファンからの空気が全量通過するか
ら、各熱交換体の放熱効率が高い。Furthermore, since the entire amount of air from the fan passes through each heat exchange body, the heat radiation efficiency of each heat exchange body is high.

さらに、３個以上の熱交換体を有する場合に、中央部の
熱交換体の入口管、出口管をファン軸と平行に設けるこ
とができ、中央部の熱交換体のタンク室を突出させる必
要がないから、最大外径を小さくすることができる。Furthermore, when there are three or more heat exchangers, the inlet and outlet pipes of the central heat exchanger can be provided parallel to the fan axis, and the tank chamber of the central heat exchanger does not need to protrude. Since there are no holes, the maximum outer diameter can be reduced.

またさらに、最もよく冷却すべき被冷却流体の熱交換体
を最も内側に配置するというように、被冷却流体の冷却
の必要に応じてその熱交換体の配置位置を定めることが
できる。Furthermore, the heat exchanger for the fluid to be cooled that should be cooled best can be placed at the innermost position, so that the position of the heat exchanger can be determined depending on the need for cooling the fluid to be cooled.

このように、この考案の効果は顕著である。In this way, the effects of this invention are remarkable.
