Description

本発明は、熱交換器、特には自動車エンジン用の給気冷却器の冷却液の循環を調整する装置、およびそれを用いた熱交換器に関する。   The present invention relates to a heat exchanger, and more particularly to an apparatus for adjusting the circulation of a coolant in a charge air cooler for an automobile engine, and a heat exchanger using the same.

この分野では、熱交換器、すなわち給気冷却器は、自動車のエンジンに供給される給気と冷却液との間の熱交換を可能にすることが知られている。熱交換器は、給気の流路と冷却液の流路とを交互に画定する熱交換束を含む。かかる熱交換器は、車両の前方に、または、少なくとも吸気口の近くに配置する必要のある、外気流により冷却される給気熱交換器とは異なり、ボンネット内、特に車両用エンジンの近傍で自由に配置することができるという利点を有する。   In this field, heat exchangers, i.e. charge air coolers, are known to allow heat exchange between the charge air supplied to the vehicle engine and the coolant. The heat exchanger includes a heat exchange bundle that alternately defines a supply air flow path and a coolant flow path. Such heat exchangers differ from supply air heat exchangers cooled by external airflow, which must be placed in front of the vehicle or at least near the air intake, in the bonnet, especially in the vicinity of the vehicle engine. It has the advantage that it can be arranged freely.

給気の温度調節のために、現在では、熱交換器またはバイパス回路のいずれかに給気を通過させることが知られている。このようにして、熱交換器を通過する空気の割合と、バイパスを通過する空気の割合に基いて、エンジンに供給される空気の温度を変更することができる。   In order to regulate the temperature of the supply air, it is now known to pass the supply air through either a heat exchanger or a bypass circuit. In this way, the temperature of the air supplied to the engine can be changed based on the proportion of air passing through the heat exchanger and the proportion of air passing through the bypass.

しかし、空気の流れを複数に分けることが必要なので、これらの解決策は比較的面倒である。   However, these solutions are relatively cumbersome because it is necessary to divide the air flow into multiple.

本発明は、この欠点を克服することを目的とし、この目的のために、熱交換器、特に、自動車エンジン用の給気冷却器の冷却液の循環を調整する装置であって、前記装置は、前記熱交換器に取り付けられるよう構成された本体を備え、前記本体は、少なくとも１つの液体循環チャンバを画定し、前記装置は、熱交換器内の冷却液の温度および／または流量を調節することを可能とする、前記チャンバ内の液体の分配手段をさらに備える装置を提案する。   The present invention aims at overcoming this drawback and for this purpose is a device for regulating the circulation of the coolant in a heat exchanger, in particular a charge air cooler for motor vehicle engines, said device comprising: A body configured to be attached to the heat exchanger, wherein the body defines at least one liquid circulation chamber and the device regulates the temperature and / or flow rate of the coolant in the heat exchanger A device further comprising means for distributing the liquid in the chamber is proposed.

冷却液回路を用いた制御を行うことにより、本発明の装置は、小型でありながら、熱交換器の給気の温度調節を確実にすることができる。さらに、熱交換器への前記装置の統合により、すぐに組み込み可能なモジュールが利用可能となる。   By performing the control using the coolant circuit, the apparatus of the present invention can ensure the temperature adjustment of the supply air of the heat exchanger while being small. Furthermore, the integration of the device into a heat exchanger makes available modules that are ready for integration.

有利には、前記本体は、チャンバ内の前記液体のための少なくとも１つの入口と、チャンバ内の前記液体のための第１および第２の出口とを備え、前記第１の出口は、熱交換器の入口に接続されるよう構成されており、前記装置は、冷却液が、前記第２の出口を通って、熱交換器の少なくとも一部をバイパスするよう構成されており、前記分配手段は、チャンバの前記第１の出口と前記第２の出口の間で、冷却液の分配を行うよう構成される。   Advantageously, the body comprises at least one inlet for the liquid in a chamber and first and second outlets for the liquid in the chamber, the first outlet being heat exchange The apparatus is configured to be connected to an inlet of a heat exchanger, and the apparatus is configured to allow coolant to bypass at least a portion of the heat exchanger through the second outlet, , Configured to distribute coolant between the first outlet and the second outlet of the chamber.

したがって、装置は、チャンバ内において、入口を入った液体の流れを、チャンバの前記第１の出口と前記第２の出口とに分配することができ、これによって、熱交換器内を循環する冷却液の流量を調節し、給気の冷却の必要に応じて、この循環を、冷却のために全部を熱交換器に流すか、部分的に冷却するために一部を熱交換器に流すか、または、冷却しないように熱交換器をバイパスするか調節することができる。また、液体循環ポンプをその定格速度で動作させ、疲労を最小限とすることができる。   Thus, the device can distribute the flow of liquid entering the inlet to the first outlet and the second outlet of the chamber, thereby cooling the circulation in the heat exchanger. Adjust the flow rate of the liquid and, depending on the need for cooling of the supply air, whether this circulation flows entirely through the heat exchanger for cooling or partially through the heat exchanger for partial cooling. Alternatively, the heat exchanger can be bypassed or adjusted so as not to cool. In addition, the fluid circulation pump can be operated at its rated speed to minimize fatigue.

本発明の他の特徴および利点は、添付の図面を参照して説明のために与えられた例示的な実施形態に関する以下の説明を読めば明らかになるであろう。   Other features and advantages of the present invention will become apparent upon reading the following description of exemplary embodiments given by way of illustration with reference to the accompanying drawings.

図１には、従来技術に従う自動車エンジン用の、エンジンの給気冷却器Ａを形成する熱交換器３を有する空気吸入モジュール１が示されている。このモジュール１は、ここでは、直接空気を供給するために、エンジンに統合されることを意図しており、図示しないシリンダヘッドに取り付けられることにより、冷却された空気Ａを、熱交換器に取り付けられた吸入マニホールド４を通して、シリンダヘッドの吸入管に向けて分配する。   FIG. 1 shows an air intake module 1 having a heat exchanger 3 forming an air charge cooler A for an automobile engine according to the prior art. This module 1 is here intended to be integrated into the engine in order to supply air directly, and is attached to a cylinder head (not shown) so that the cooled air A is attached to the heat exchanger. It distributes through the suction manifold 4 to the suction pipe of the cylinder head.

熱交換器３は、例えば、過給器からの高温の圧縮空気を受け入れるが、この圧縮空気は、ここでは、前記熱交換器の空気吸入マニホールド５を介して熱交換器に入る。この空気は、熱交換器３を通過する間に冷却され、前記吸入マニホールド４で前記熱交換器から流れ出る。熱交換は、空気と、熱交換器を循環する冷却液Ｌとの間で行われる。より具体的には、この空気の冷却は、給気の循環路と冷却液の循環路を交互に画定するプレート８のスタックで構成された、熱交換器の熱交換束７を用いて行われる。図に示すように、冷却液Ｌは、熱交換器３から離間した作動ポンプ９を用いて、熱交換器内を、より正確には、熱交換束内を循環される。   The heat exchanger 3 receives hot compressed air from a supercharger, for example, which here enters the heat exchanger via the air intake manifold 5 of the heat exchanger. This air is cooled while passing through the heat exchanger 3 and flows out of the heat exchanger at the suction manifold 4. Heat exchange is performed between the air and the coolant L circulating in the heat exchanger. More specifically, this air cooling is performed using a heat exchanger bundle 7 of a heat exchanger, which is composed of a stack of plates 8 that alternately define a supply air circulation path and a coolant circulation path. . As shown in the figure, the coolant L is circulated in the heat exchanger, more precisely in the heat exchange bundle, using an operating pump 9 spaced from the heat exchanger 3.

本発明に従うエンジンの吸入モジュール１を図２に示す。熱交換器３は、図１のそれと同様である。   An engine intake module 1 according to the invention is shown in FIG. The heat exchanger 3 is the same as that of FIG.

本発明によれば、図２に示すように、熱交換器３内の冷却液Ｌの循環を調整する装置１は、冷却液Ｌの循環路上に配置される。この装置１１は熱交換器３に装着されるが、ここでは、図５および６にも示すように、熱交換器の同じ側に、冷却液Ｌの入口１３および出口１５を備える。前記装置は、前記熱交換器に取り付けられられるよう構成された本体１７を備え、前記本体は、液体の循環のための少なくとも１つのチャンバ１９を画定する。さらに、前記装置は、チャンバ内の前記液体を分配し、熱交換器内の冷却液の温度および／または流量を調節する可能性を与える。このように、冷却液によって給気の温度調整を確実に行うことが可能であり、これは、熱交換器に統合された装置を用いて行われる。   According to the present invention, as shown in FIG. 2, the device 1 for adjusting the circulation of the cooling liquid L in the heat exchanger 3 is arranged on the circulation path of the cooling liquid L. The apparatus 11 is mounted on the heat exchanger 3, and here, as shown in FIGS. 5 and 6, an inlet 13 and an outlet 15 for the coolant L are provided on the same side of the heat exchanger. The apparatus comprises a body 17 configured to be attached to the heat exchanger, the body defining at least one chamber 19 for circulation of liquid. Furthermore, the device distributes the liquid in the chamber and gives the possibility to adjust the temperature and / or flow rate of the cooling liquid in the heat exchanger. In this way, it is possible to reliably adjust the temperature of the supply air by means of the cooling liquid, which is performed using a device integrated in the heat exchanger.

前記本体１７は、ここでは、チャンバ１９内の前記液体のための入口２１と、チャンバからの前記液体の第１の出口２３および第２の出口２５を有する。前記第１の出口２３は熱交換器の入口１３に接続されているが、装置は、冷却液が前記第２の出口２５を介して、例えば、前記第２の出口２５および熱交換器の出口１５に接続された、装置のバイパス路２７を通って、熱交換器の少なくとも一部をバイパスできるように構成されている。分配手段１２は、ここでは、割当手段２９を用いて、チャンバの前記第１の出口２３と前記第２の出口２５の間で、チャンバ内の前記液体の分配を行い、熱交換器の入口２１とバイパス路２７の間で液体を割り当てるように構成される。   The body 17 here has an inlet 21 for the liquid in the chamber 19 and a first outlet 23 and a second outlet 25 for the liquid from the chamber. Although the first outlet 23 is connected to the inlet 13 of the heat exchanger, the apparatus is arranged such that the coolant passes through the second outlet 25, for example, the second outlet 25 and the outlet of the heat exchanger. The heat exchanger is configured to be able to bypass at least a portion of the heat exchanger through a bypass passage 27 connected to the apparatus 15. The distribution means 12 here uses the assignment means 29 to distribute the liquid in the chamber between the first outlet 23 and the second outlet 25 of the chamber, and to the heat exchanger inlet 21. And a liquid is allocated between the bypass passage 27.
