Description

本発明は冷却システム、放熱システムや加熱システム等用の熱交換器に関するもので、特にコンパクト性を要求されるシステムで使用される熱交換器に関するものである。   The present invention relates to a heat exchanger for a cooling system, a heat dissipation system, a heating system, and the like, and more particularly to a heat exchanger used in a system that requires compactness.

従来、この種の熱交換器としては、管とフィンとから構成されたものが一般的であるが、近年はそのコンパクト化を図るために、管径及び管ピッチを小さくし、管を高密度化する傾向にある。その極端な形態としては、管外径が０．５ｍｍ程度の非常に細い管のみから熱交換部が構成されたものがある（例えば、特許文献１参照）。   Conventionally, this type of heat exchanger is generally composed of tubes and fins. However, in recent years, in order to achieve compactness, the tube diameter and tube pitch are reduced, and the tubes are made dense. It tends to become. As an extreme form thereof, there is one in which the heat exchanging portion is composed only of a very thin tube having a tube outer diameter of about 0.5 mm (for example, see Patent Document 1).

図１２は、特許文献１に記載された従来の熱交換器の正面図である。図１３は、図１２のＡ−Ａ線断面図である。   FIG. 12 is a front view of a conventional heat exchanger described in Patent Document 1. FIG. 13 is a cross-sectional view taken along line AA in FIG.

従来の熱交換器は、所定間隔を置いて対向配置される入口ヘッダー１と出口ヘッダー２と、入口ヘッダー１と出口ヘッダー２の間に断面円環の複数の管３が配置され、管３の外部を空気等の外部流体が流通される熱交換コア４が構成されている。管３内を流通する内部流体としては主に水や不凍液が用いられ、外部流体としては空気が主流であり、それぞれが流通し、熱交換を行う。   In the conventional heat exchanger, an inlet header 1 and an outlet header 2 which are opposed to each other with a predetermined interval, and a plurality of tubes 3 having a circular cross section are arranged between the inlet header 1 and the outlet header 2. A heat exchange core 4 through which an external fluid such as air is circulated is configured. Water or antifreeze is mainly used as an internal fluid that circulates in the pipe 3, and air is mainly used as an external fluid, and each circulates and performs heat exchange.

そして、管３を碁盤目状に配置するとともに、管３の外径を０．２ｍｍ以上０．８ｍｍ以下とし、隣接する管３のピッチを管外径で除した値を０．５以上３．５以下とすることで、使用動力に対する熱交換量を大幅に向上できるとしている。
特開２００１−１１６４８１号公報 And while arrange | positioning the pipe | tube 3 in grid shape, the outer diameter of the pipe | tube 3 shall be 0.2 mm or more and 0.8 mm or less, and the value which remove | divided the pitch of the adjacent pipe | tube 3 by the pipe outer diameter is 0.5-3. By setting it to 5 or less, it is said that the amount of heat exchange for the power used can be greatly improved.
JP 2001-116481 A

実使用上、熱交換器はダクト内に設置されたり、送風機により外部流体を通風させる等により、熱交換器前面に流入する外部流体の速度に分布ができるため、熱交換量にも分布ができる。また、外部流体の熱交換器流入側では外部流体と内部流体の温度差が大きく下流になるほど温度差が小さくなり、熱交換量は小さくなる。   In actual use, the heat exchanger can be distributed in the heat exchange amount because it can be distributed in the speed of the external fluid flowing into the front surface of the heat exchanger by installing it in the duct or ventilating the external fluid with a blower, etc. . In addition, on the heat exchanger inflow side of the external fluid, the temperature difference decreases as the temperature difference between the external fluid and the internal fluid increases, and the heat exchange amount decreases.

しかしながら、上記従来の熱交換器では、管３のピッチが均等であるため、熱交換量が小さい領域を基準に熱交換器を設計すると、熱交換量が大きい領域では熱交換量が不足し、熱交換量が大きい領域を基準に熱交換器を設計すると、管投入量が増し、コストアップになるという課題を有していた。   However, in the above conventional heat exchanger, since the pitch of the tubes 3 is uniform, when the heat exchanger is designed based on the region where the heat exchange amount is small, the heat exchange amount is insufficient in the region where the heat exchange amount is large, When a heat exchanger is designed based on a region where the heat exchange amount is large, there is a problem that the amount of pipe input increases and the cost increases.

本発明は、上記従来の課題を解決するもので、適正な熱交換量を得、かつ、安価な熱交換器を提供することを目的とする。   An object of the present invention is to solve the above-described conventional problems, and to obtain an appropriate heat exchange amount and to provide an inexpensive heat exchanger.

上記従来の課題を解決するために、本発明の熱交換器は、多数の貫通穴を備えた基板間に管内が前記貫通穴と連通し前記基板の表面から略垂直に設けられ、管外を外部流体が管内を内部流体が流動する管の配置が異なる熱交換ブロックを連結したことを特徴とするものである。   In order to solve the above-described conventional problems, the heat exchanger according to the present invention is configured such that the inside of a tube communicates with the through holes between substrates having a large number of through holes and is provided substantially vertically from the surface of the substrate. It is characterized in that heat exchange blocks having different arrangements of pipes through which the external fluid flows in the pipe are connected.

これにより、熱交換量が大きい領域には、管ピッチを小さくした熱交換ブロックを配置し、熱交換量が小さい領域には、管ピッチを大きくした熱交換ブロックを設置することにより、局所の熱交換量に応じて管を投入することができるため、適正な熱交換量を得、かつ、安価な熱交換器を提供することができる。   As a result, a heat exchange block with a reduced pipe pitch is arranged in a region where the heat exchange amount is large, and a heat exchange block with a large tube pitch is installed in a region where the heat exchange amount is small. Since the pipes can be charged according to the exchange amount, an appropriate heat exchange amount can be obtained and an inexpensive heat exchanger can be provided.

また、本発明の熱交換器は、外部流体の流速が大きい個所ほど前記管の配置間隔が小さい前記熱交換ブロックを設けたことを特徴とするものである。   The heat exchanger according to the present invention is characterized in that the heat exchange block having a smaller arrangement interval of the tubes is provided at a location where the flow rate of the external fluid is larger.

これにより、外部流体の速度が速い領域は熱交換量が大きくなり、外部流体の流速が遅い領域は熱交換量が小さくなるため、局所の熱交換量に応じて管を投入することができ、適正な熱交換量を得、かつ、安価な熱交換器を提供することができる。   Thereby, the heat exchange amount is large in the region where the speed of the external fluid is high, and the heat exchange amount is small in the region where the flow rate of the external fluid is low, so the pipe can be introduced according to the local heat exchange amount, An appropriate heat exchange amount can be obtained, and an inexpensive heat exchanger can be provided.

また、本発明の熱交換器は外部流体上流側ほど配置間隔が小さい前記熱交換ブロックを設けたことを特徴とするものである。   The heat exchanger of the present invention is characterized in that the heat exchange block having a smaller arrangement interval is provided on the upstream side of the external fluid.

これにより、外部流体上流側では外部流体と内部流体の温度差が大きく熱交換量が大きくなり、下流側では外部流体と内部流体の温度差が小さく熱交換量が小さくなるため、局所の熱交換量に応じて管を投入することができ、適正な熱交換量を得、かつ、安価な熱交換器を提供することができる。   As a result, the temperature difference between the external fluid and the internal fluid is large on the upstream side of the external fluid and the amount of heat exchange is large, and the temperature difference between the external fluid and the internal fluid is small on the downstream side and the amount of heat exchange is small. A pipe | tube can be thrown in according to quantity, the appropriate amount of heat exchange can be obtained, and an inexpensive heat exchanger can be provided.

また、本発明の熱交換器は、前記基板を接合して前記熱交換ブロック相互を連結することを特徴とするものである。   The heat exchanger of the present invention is characterized in that the heat exchange blocks are connected to each other by joining the substrates.

これにより、管相互を直接接続する必要が無く、容易に熱交換ブロックを連結することができ、安価な熱交換器を提供することができる。   Thereby, it is not necessary to connect the pipes directly, the heat exchange blocks can be easily connected, and an inexpensive heat exchanger can be provided.

また、本発明の熱交換器は前記管が管内に複数の流路を備えた多穴管であることを特徴とするものである。   The heat exchanger according to the present invention is characterized in that the tube is a multi-hole tube having a plurality of flow paths in the tube.

これにより、管を基板に接続する本数が低減でき、容易に熱交換器を製作することができ、安価な熱交換器を提供することができる。   As a result, the number of pipes connected to the substrate can be reduced, a heat exchanger can be easily manufactured, and an inexpensive heat exchanger can be provided.

本発明の熱交換器は、局所の熱交換量に応じた設計ができるため、適正な熱交換量を得、かつ安価に熱交換器を提供することができる。   Since the heat exchanger of the present invention can be designed according to the local heat exchange amount, an appropriate heat exchange amount can be obtained and the heat exchanger can be provided at low cost.

請求項１に記載の発明は、多数の貫通穴を備えた基板間に管内が貫通穴と連通し基板の表面から略垂直に設けられ、管外を外部流体が管内を内部流体が流動する管の配置が異なる熱交換ブロックを連結したことを特徴とするものであり、熱交換量が大きい領域には、管ピッチを小さくした熱交換ブロックを配置し、熱交換量が小さい領域には、管ピッチを大きくした熱交換ブロックを配置することにより、局所の熱交換量に応じて管を投入することができ、適正な熱交換量を得、かつ、安価な熱交換器を提供することができる。   According to the first aspect of the present invention, the inside of the tube communicates with the through holes between the substrates having a large number of through holes and is provided substantially perpendicularly from the surface of the substrate, and the outside fluid flows outside the tube and the inside fluid flows inside the tube. The heat exchange blocks having different arrangements are connected to each other. A heat exchange block having a small pipe pitch is arranged in a region where the heat exchange amount is large, and a tube is arranged in a region where the heat exchange amount is small. By arranging a heat exchange block with a large pitch, it is possible to introduce a tube according to the local heat exchange amount, obtain an appropriate heat exchange amount, and provide an inexpensive heat exchanger. .

請求項２に記載の発明は、請求項１に記載の発明において、外部流体の流速が大きい個所ほど管の配置間隔が小さい熱交換ブロックを設けたことを特徴とするものであり、熱交換器をダクト内に設置した場合等、外部流体の速度分布がある場合、外部流体の速度が速い領域は熱交換量が大きくなり、外部流体の流速が遅い領域は熱交換量が小さくなるため、局所の熱交換量に応じて管を投入することができ、適正な熱交換量を得、かつ、安価な熱交換器を提供することができる。   The invention according to claim 2 is characterized in that, in the invention according to claim 1, a heat exchange block having a smaller arrangement interval of the tubes is provided at a place where the flow velocity of the external fluid is larger. When there is a velocity distribution of the external fluid, such as when installed in a duct, the heat exchange amount is large in the region where the external fluid velocity is high, and the heat exchange amount is small in the region where the external fluid velocity is slow. Therefore, it is possible to supply a pipe according to the amount of heat exchange, to obtain an appropriate amount of heat exchange, and to provide an inexpensive heat exchanger.

請求項３に記載の発明は、請求項１または２に記載の発明において、外部流体上流側ほど配置間隔が小さい熱交換ブロックを設けたことを特徴とするものであり、外部流体上流側では外部流体と内部流体の温度差が大きく熱交換量が大きくなり、下流側では外部流体と内部流体の温度差が小さく熱交換量が小さくなるため、局所の熱交換量に応じて管を投入することができ、適正な熱交換量を得、かつ、安価な熱交換器を提供することができる。   The invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, a heat exchange block having a smaller arrangement interval is provided on the upstream side of the external fluid. Since the temperature difference between the fluid and the internal fluid is large and the heat exchange amount is large, and the temperature difference between the external fluid and the internal fluid is small on the downstream side and the heat exchange amount is small, pipes should be inserted according to the local heat exchange amount. Therefore, an appropriate heat exchange amount can be obtained, and an inexpensive heat exchanger can be provided.

請求項４に記載の発明は、請求項１から３のいずれか一項に記載の発明において、基板を接合して熱交換ブロック相互を連結することを特徴とするものであり、容易に熱交換ブロックを連結することができ、安価な熱交換器を提供することができる。   The invention according to claim 4 is characterized in that, in the invention according to any one of claims 1 to 3, the heat exchange blocks are connected to each other by joining the substrates, and heat exchange can be easily performed. The blocks can be connected, and an inexpensive heat exchanger can be provided.

熱交換器１０は熱交換ブロック２０を相互に連結し、上下にヘッダー４０を連結して構成されている。   The heat exchanger 10 is configured by connecting the heat exchange blocks 20 to each other and connecting headers 40 vertically.

熱交換ブロック２０は多数の貫通穴を備えた基板５０間に管内が貫通穴と連通し基板５０の表面から略垂直に設けられた管６０から構成されており、管ピッチが密な熱交換ブロック２０ａは外部流体の流れ方向に垂直な管ピッチが密になっており、管ピッチが粗な熱交換ブロック２０ｂは外部流体の流れ方向に垂直な管ピッチが粗になっている。管６０は管内に複数の流路７０を備えている。本実施の形態では管内に複数の流路７０を備えた管６０を用いたが、管内流路が１つの円管、楕円管、角管でもよい。   The heat exchanging block 20 is composed of a pipe 60 which is connected to the through holes between the substrates 50 having a large number of through holes and is provided substantially perpendicularly from the surface of the substrate 50, and has a dense tube pitch. 20a has a dense pipe pitch perpendicular to the flow direction of the external fluid, and the heat exchange block 20b having a coarse pipe pitch has a coarse pipe pitch perpendicular to the flow direction of the external fluid. The tube 60 includes a plurality of flow paths 70 in the tube. In the present embodiment, the pipe 60 having a plurality of flow paths 70 in the pipe is used. However, the pipe flow path may be a single circular pipe, an elliptical pipe, or a square pipe.

ここで熱交換器１０は管ピッチが密な熱交換ブロック２０ａを中央に２段連結し、それぞれ左右に管ピッチが粗な熱交換ブロック２０ｂが連結されている。熱交換ブロック２０相互はそれぞれの基板５０を連結している。熱交換ブロック２０ａと熱交換ブロック２０ｂの配置は本実施の形態に限定されるものではなく、熱交換器の設置場所や使用条件等により適切に組み合わせて使用する。   Here, the heat exchanger 10 has a heat exchange block 20a with a dense pipe pitch connected in two stages in the center, and a heat exchange block 20b with a coarse pipe pitch is connected to the left and right. The heat exchange blocks 20 connect the substrates 50 to each other. The arrangement of the heat exchanging block 20a and the heat exchanging block 20b is not limited to the present embodiment, and the heat exchanging block 20a and the heat exchanging block 20b are used in an appropriate combination depending on the installation place of the heat exchanger and the use conditions.

以上のように構成された熱交換器について、ダクト内に設置された場合を例に以下その動作、作用を説明する。   About the heat exchanger comprised as mentioned above, the operation | movement and an effect | action are demonstrated below for the case where it installs in a duct as an example.

ヘッダー４０ａから流入した内部流体は分岐されて管内流路７０内を流れる。また、外部流体は管６０相互間を流れ、内部流体と外部流体が熱交換を行い、ヘッダー４０ｂより内部流体は流出する。   The internal fluid flowing in from the header 40a is branched and flows in the in-pipe flow path 70. The external fluid flows between the pipes 60, the internal fluid and the external fluid exchange heat, and the internal fluid flows out of the header 40b.

この際、熱交換器１０をダクト内に設置した場合、外部流体の流れが層流であればダクト壁付近の流速は遅く、ダクト中心部の流速は速くなる。本実施の形態の熱交換器１０は、外部流体の流速が速く熱交換量が大きい領域には管６０を密に配した熱交換ブロック２０ａを設置し、外部流体の流速が小さく熱交換量が小さい領域には管６０を粗に配した熱交換ブロック２０ｂを設置したので、熱交換量に応じて管を投入することができるとともに、容易に製作ができる。   At this time, when the heat exchanger 10 is installed in the duct, if the flow of the external fluid is a laminar flow, the flow velocity near the duct wall is slow and the flow velocity in the center of the duct is fast. In the heat exchanger 10 of the present embodiment, the heat exchange block 20a in which the pipes 60 are densely arranged is installed in a region where the flow rate of the external fluid is fast and the heat exchange amount is large, and the flow rate of the external fluid is small and the heat exchange amount is large. Since the heat exchange block 20b in which the pipes 60 are roughly arranged is installed in a small area, the pipes can be introduced according to the heat exchange amount and can be easily manufactured.

以上のように、本実施の形態においては、管内に複数の流路７０を備えた管６０を基板５０から略垂直に密に配置した熱交換ブロック２０ａを中央に配置し、その両側に管６０を基板５０から略垂直に粗に配置した熱交換ブロック２０ｂを配置したことにより、ダクト内に設置した場合など周辺部よりも中央部の風速が速い場合、熱交換量が大きくなる中央部に管６０を密に投入することで熱交換量に応じて管を投入することができ、適正な熱交換量が得られ、かつ安価に熱交換器１０を製作することができる。   As described above, in the present embodiment, the heat exchanging block 20a in which the pipe 60 having the plurality of flow paths 70 in the pipe is densely arranged substantially vertically from the substrate 50 is arranged in the center, and the pipe 60 is provided on both sides thereof. When the heat exchange block 20b is arranged roughly vertically from the substrate 50, when the wind speed is higher in the central portion than in the peripheral portion, such as when installed in a duct, the tube is formed in the central portion where the heat exchange amount increases.

本実施の形態の熱交換器１００は外部流体の流れ方向に熱交換ブロック２０を２列連結しており、外部流体上流側の熱交換ブロック２０ａは管ピッチが密であり、下流側の熱交換ブロック２０ｂは管ピッチが粗である。なお、本実施の形態では２列の場合を示したが、２列以上であればよく、また管ピッチが異なる熱交換ブロック２０を２種類用いているが、２種類以上であればよい。   In the heat exchanger 100 of the present embodiment, two rows of heat exchange blocks 20 are connected in the flow direction of the external fluid, the heat exchange block 20a on the upstream side of the external fluid has a dense pipe pitch, and heat exchange on the downstream side. The block 20b has a rough pipe pitch. In the present embodiment, the case of two rows is shown. However, it is sufficient if there are two or more rows, and two types of heat exchange blocks 20 having different tube pitches are used, but two or more types may be used.

以上のように構成された熱交換器について、以下その動作、作用を説明する。   About the heat exchanger comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

ヘッダー４０ａから流入した内部流体は分岐されて管内流路７０内を流れる。また、外部流体は管６０相互間を流れ、内部流体と外部流体が熱交換を行い、ヘッダー４０ｂより内部流体は流出する。   The internal fluid flowing in from the header 40a is branched and flows in the in-pipe flow path 70. The external fluid flows between the pipes 60, the internal fluid and the external fluid exchange heat, and the internal fluid flows out of the header 40b.

外部流体の上流側では外部流体と内部流体との温度差が大きく、熱交換量が大きくなり、外部流体が熱交換器１００内を通過するに従い、外部流体と内部流体の温度差は小さくなり、熱交換量は低下する。この際、熱交換量が大きい外部流体の上流側に管ピッチが密な熱交換ブロック２０ａを配置し、下流側に管ピッチが粗な熱交換ブロック２０ｂを配置することにより、熱交換量が大きい領域に管６０を密に、熱交換量が小さい領域に管６０を粗に配置することが容易にできるため、熱交換器を安価に提供することができる。   On the upstream side of the external fluid, the temperature difference between the external fluid and the internal fluid is large, the amount of heat exchange increases, and as the external fluid passes through the heat exchanger 100, the temperature difference between the external fluid and the internal fluid decreases, The amount of heat exchange decreases. At this time, the heat exchange block 20a having a dense pipe pitch is disposed on the upstream side of the external fluid having a large heat exchange amount, and the heat exchange block 20b having a coarse pipe pitch is disposed on the downstream side, whereby the heat exchange amount is large. Since it is possible to easily arrange the pipe 60 densely in the area and the pipe 60 roughly in the area where the amount of heat exchange is small, the heat exchanger can be provided at low cost.

Therefore, the heat exchanger 100 can be manufactured at a low cost by obtaining an appropriate heat exchange amount.

また、本実施の形態では、基板５０相互を接合し、熱交換ブロック２０を連結しているため、容易に熱交換ブロック２０を連結することができ、安価に熱交換器を提供することができる。   Moreover, in this Embodiment, since the board | substrates 50 are joined and the heat exchange block 20 is connected, the heat exchange block 20 can be connected easily and a heat exchanger can be provided cheaply. .

また、本実施の形態では、複数の管内流路７０を備えた管６０を用いているため、管６０の本数が低減でき、基板５０への接続工数が低減でき、安価に熱交換器を提供することができる。   In this embodiment, since the pipe 60 provided with a plurality of in-pipe flow paths 70 is used, the number of pipes 60 can be reduced, the number of connection steps to the substrate 50 can be reduced, and a heat exchanger can be provided at low cost. can do.

以上のように、本発明にかかる熱交換器は、非常に優れた熱交換性能を維持しながら、安価に実現でき、冷凍冷蔵機器や空調機器用の熱交換器や、廃熱回収機器等の用途にも適用できる。   As described above, the heat exchanger according to the present invention can be realized at low cost while maintaining very excellent heat exchange performance, such as heat exchangers for refrigeration equipment and air conditioning equipment, waste heat recovery equipment, etc. It can also be applied to applications.
