Description

本発明は、流体の入口用および／または出口用の配管が接続される配管接続部を備えた熱交換器に関する。   The present invention relates to a heat exchanger provided with a pipe connection portion to which pipes for fluid inlet and / or outlet are connected.

従来、熱交換媒体等の流体の入口用および／または出口用の配管が接続される配管接続部を備えた熱交換器において、配管接続部は、プレス成形した板材を最中状に接合して形成されていた。たとえば特許文献１に記載の熱交換器においては、配管接続部は、接続される配管の外形寸法に合わせた半円筒状部をそれぞれに有する２枚の板材が最中状に接合されて円筒状に形成される。   2.

特許文献１に記載の熱交換器においては、２枚の板材を組み合わせて配管差し込み口を形成するため、配管差し込み口の真円度を高くすることが困難であった。そして、配管差し込み口の真円度が低いと、熱交換器コアの気密検査を実施するための気密検査治具を取り付けた場合に、気密性が十分に保持されないおそれがあった。   In the heat exchanger described in Patent Document 1, since the pipe insertion port is formed by combining two plate members, it is difficult to increase the roundness of the pipe insertion port. If the roundness of the pipe insertion port is low, there is a possibility that the airtightness may not be sufficiently maintained when the airtight inspection jig for performing the airtight inspection of the heat exchanger core is attached.

そこで、従来は配管差し込み口に外部配管を接合した後にコアの気密検査を実施していたが、気密検査時には外部配管を接合したコアを気密検査機の中に収めなければならないため、気密検査機は大型化せざるを得なかった。さらに、コアと配管を炉中で一体ろう付けする場合には、各種形状、各種長さの配管に対応できるようにするため、ろう付け炉も大型化せざるを得なかった。また、従来はコアが気密検査をパスせず仕損品となった際に、外部配管を無駄に廃棄することとなるという欠点があった。   Therefore, in the past, the airtightness inspection of the core was carried out after joining the external piping to the pipe insertion port. However, the airtightness inspection machine must be placed in the airtightness inspection machine during the airtightness inspection. Had to be enlarged. Furthermore, when the core and the pipe are integrally brazed in the furnace, the brazing furnace has to be increased in size so as to be compatible with pipes of various shapes and lengths. Further, conventionally, when the core does not pass the airtight inspection and becomes a defective product, there is a disadvantage that the external piping is wasted.

特許文献２に記載の熱交換器においては、単一部材であるブロック状部材の一部が配管差し込み口となるので、配管差し込み口の真円度を高くすることは比較的容易である。しかし、板状部材の構造が複雑であるため、加工コストが増大するという欠点があった。   In the heat exchanger described in Patent Document 2, since a part of the block-shaped member that is a single member serves as a pipe insertion port, it is relatively easy to increase the roundness of the pipe insertion port. However, since the structure of the plate-like member is complicated, there is a disadvantage that the processing cost increases.

このような現状に鑑み、本発明の課題は、低い加工コストで外部配管の無駄な廃棄を回避し、かつ気密検査用設備やろう付け炉を小型化することができる熱交換器を提供することにある。とくに車両空調装置用熱交換器においては、接続される外部配管の寸法や形状が適用車種ごとに大きく異なるので、かかる課題は重大なものとなっていた。   In view of such a current situation, an object of the present invention is to provide a heat exchanger capable of avoiding wasteful disposal of external piping at a low processing cost and miniaturizing an airtight inspection facility and a brazing furnace. It is in. In particular, in a heat exchanger for a vehicle air conditioner, since the dimensions and shape of the external pipe to be connected vary greatly depending on the applicable vehicle type, such a problem has become serious.

上記課題を解決するために、本発明に係る熱交換器は、流体の入口用および／または出口用の配管が接続される配管接続部を備えた熱交換器において、前記配管接続部が、前記配管の差し込み穴を有し、該差し込み穴に連通する位置から熱交換器本体内通路に連通可能な位置まで延び、部材厚み方向に貫通されている内部通路を有するブロック状部材と、該ブロック状部材の部材厚み方向一面側に接合され、前記内部通路を閉塞するとともに、前記熱交換器本体内通路に連通可能な位置にて前記内部通路を前記熱交換器本体内通路に連通させる開口を有する第１の板状部材と、前記ブロック状部材の部材厚み方向他面側に接合され、前記内部通路を外部に対して閉塞する第２の板状部材とからなることを特徴とするものからなる。   In order to solve the above-described problems, a heat exchanger according to the present invention includes a pipe connection portion to which pipes for fluid inlet and / or outlet are connected, wherein the pipe connection portion includes the pipe connection portion. A block-like member having a pipe insertion hole, extending from a position communicating with the insertion hole to a position capable of communicating with the passage in the heat exchanger body, and having an internal passage penetrating in the member thickness direction; A member is joined to one side in the thickness direction of the member, has an opening that closes the internal passage and communicates the internal passage with the internal passage in the heat exchanger at a position where the internal passage can communicate with the internal passage in the heat exchanger. It consists of a 1st plate-shaped member and the 2nd plate-shaped member joined to the member thickness direction other surface side of the said block-shaped member, and obstruct | occludes the said internal channel | path with respect to the exterior. .

このような本発明の熱交換器において配管接続部は、部材厚み方向に貫通されている内部通路を有するブロック状部材を部材厚み方向の両面側から一対の板状部材によって挟み込むことにより内部通路を外部に対して閉塞しつつ、配管差し込み穴についてはブロック状部材に形成することにより構成される。かかる簡易な構造により配管接続部を形成することで、加工コストを低く抑えつつ、所望の内部通路を形成しつつ、配管差し込み口の真円度を高くすることができる。その結果、気密検査時における検査用の配管の接続部の気密性が十分に確保され、正規の外部配管を接続しない状態で気密検査を行なえることから、気密検査用設備を小型化できる。また、外部配管のろう付けについては、炉中一体ろう付けではなく、気密検査合格後の熱交換器コアに対してトーチろう付け等により行なうことが可能になるので、ろう付け炉の小型化も可能になる。   In such a heat exchanger of the present invention, the pipe connecting portion is configured such that the block-shaped member having the internal passage penetrating in the thickness direction of the member is sandwiched by a pair of plate-like members from both sides in the thickness direction of the member. The pipe insertion hole is formed by forming it in a block-like member while closing the outside. By forming the pipe connection portion with such a simple structure, it is possible to increase the roundness of the pipe insertion port while forming a desired internal passage while keeping processing costs low. As a result, the airtightness of the connection portion of the inspection pipe at the time of the airtight inspection is sufficiently ensured, and the airtight inspection can be performed without connecting a regular external pipe, so that the equipment for the airtight inspection can be downsized. In addition, brazing of external piping can be performed not by integral brazing in the furnace but by torch brazing on the heat exchanger core after passing the hermetic inspection, so the brazing furnace can be downsized. It becomes possible.

本発明の熱交換器において内部通路は、上記ブロック状部材内で屈曲または湾曲して延びる部分を有していることが好ましい。内部通路がかかる構造を有することにより、配管接続部全体がコンパクトになり、気密検査用設備やろう付け炉をより小型化することができる。   In the heat exchanger of the present invention, it is preferable that the internal passage has a portion extending in a bent or curved manner in the block-shaped member. By having such a structure of the internal passage, the entire pipe connection part becomes compact, and the equipment for airtight inspection and the brazing furnace can be further downsized.

本発明の熱交換器においては、上記ブロック状部材の部材厚み方向における一面側と他面側の外形形状を対称形状に形成することができる。かかる構造を採用することにより、配管接続部が熱交換器コアの左右いずれの側に設けられる場合にも、共通のブロック状部材を使用することができる。さらにこの場合、第１の板状部材と第２の板状部材の外形形状を同一形状に形成することにより、開口の有無以外の点で両板状部材の形状が同一となるので、板状部材の材料を共通化することができる。   In the heat exchanger of the present invention, the outer shapes of the one surface side and the other surface side in the member thickness direction of the block-shaped member can be formed symmetrically. By adopting such a structure, a common block-like member can be used even when the pipe connection portion is provided on either the left or right side of the heat exchanger core. Further, in this case, since the outer shapes of the first plate member and the second plate member are formed in the same shape, the shapes of both the plate members are the same except for the presence or absence of the opening. The material of the member can be made common.

また、本発明の熱交換器においては、上記ブロック状部材の部材厚み方向における一面側と他面側の外形形状を非対称形状に形成することもできる。この場合には、第１の板状部材と第２の板状部材の外形形状は互いに異なる外形形状に形成される。   Moreover, in the heat exchanger of this invention, the external shape of the one surface side and other surface side in the member thickness direction of the said block-shaped member can also be formed in an asymmetrical shape. In this case, the outer shapes of the first plate member and the second plate member are formed in different outer shapes.

このような本発明の熱交換器において上記ブロック状部材は、内部通路が型材長手方向に延在するように押出成形された押出型材を、上記ブロック状部材の厚みに相当する厚みごとに切断することによってブロック状部材原材を形成し、機械加工により、原材の外形を所定形状に加工するとともに差し込み穴を加工することにより形成されていることが好ましい。かかる工程を採用することにより、内部構造が既に加工されたブロック状部材原材に、簡易な機械加工を施すだけで、ブロック状部材の外形および配管差し込み穴を容易に形成することができる。   In such a heat exchanger of the present invention, the block-shaped member cuts the extruded mold material that is extruded so that the internal passage extends in the longitudinal direction of the mold material, for each thickness corresponding to the thickness of the block-shaped member. Thus, it is preferable that the block-shaped member raw material is formed, and the outer shape of the raw material is processed into a predetermined shape by machining and the insertion hole is processed. By adopting such a process, it is possible to easily form the outer shape of the block-shaped member and the piping insertion hole only by performing simple machining on the block-shaped member raw material whose internal structure has already been processed.

本発明の熱交換器においては、入口用および出口用の配管の差し込み穴が、ともに、同一のブロック状部材に形成されていることが好ましい。すなわち、入口用および出口用の両配管を単一の配管接続部に接続し、これを単一のブロック状部材から形成することにより、加工の手間を軽減することができる。また、配管接続部がコンパクトになるので、気密検査用設備やろう付け炉をより小型化することができる。   In the heat exchanger of the present invention, it is preferable that both the insertion holes for the inlet and outlet pipes are formed in the same block-shaped member. That is, both the inlet and outlet pipes are connected to a single pipe connecting portion and formed from a single block-like member, thereby reducing the processing effort. In addition, since the pipe connection portion becomes compact, the equipment for airtight inspection and the brazing furnace can be further downsized.

本発明の熱交換器において、第１の板状部材および第２の板状部材と上記ブロック状部材はろう付けにより接合されていることが好ましい。かかる接合方法を採用することにより、配管接続部を含めた熱交換器コアを炉中で一体ろう付けすることも可能となる。   In the heat exchanger of the present invention, it is preferable that the first plate-like member, the second plate-like member, and the block-like member are joined by brazing. By adopting such a joining method, the heat exchanger core including the pipe connecting portion can be integrally brazed in the furnace.

このような本発明の熱交換器において、配管接続部に接続される配管には、正規の外部配管以外に、熱交換器の気密検査用の配管が含まれることが好ましい。すなわち、本発明に係る配管接続部に気密検査用の配管を接続して気密検査を実施することで、気密検査時における配管接続部の気密性が十分に確保されるという本発明の効果が十分に発揮される。   In such a heat exchanger of the present invention, it is preferable that the pipe connected to the pipe connection portion includes a pipe for an airtight inspection of the heat exchanger in addition to the regular external pipe. That is, the effect of the present invention that the airtightness of the pipe connection portion at the time of the airtight inspection is sufficiently secured by connecting the pipe for the airtight inspection to the pipe connection portion according to the present invention and performing the airtight inspection is sufficient. To be demonstrated.

本発明の熱交換器は、積層型熱交換器において好適に用いることができる。たとえば、積層された多数のチューブのうちの端部チューブと外部配管を、本発明の熱交換器における配管接続部を用いて接続することによって、加工コストを低く抑えつつ、配管接続部の気密性を十分に確保し、気密検査用設備やろう付け炉を小型化することができるという本発明の効果が十分に発揮される。   The heat exchanger of the present invention can be suitably used in a stacked heat exchanger. For example, by connecting the end tubes and the external pipes of the laminated tubes using the pipe connection part in the heat exchanger of the present invention, the airtightness of the pipe connection part is suppressed while keeping the processing cost low. Thus, the effect of the present invention can be sufficiently exerted such that the airtightness inspection equipment and the brazing furnace can be reduced in size.

本発明の熱交換器は、車両空調装置用熱交換器として好適に用いることができる。すなわち、車両空調装置用熱交換器においては、接続される外部配管の寸法や形状が適用車種ごとに多様であるため、外部配管を接続する前の熱交換器コア単独について気密検査を行うことができるメリットは大きい。具体的には、ろう付け炉や気密検査機の小型化というメリットのほか、気密検査後における、コア保管スペースの節約やコア輸送効率の向上というメリットも多大なものである。   The heat exchanger of the present invention can be suitably used as a heat exchanger for a vehicle air conditioner. That is, in the heat exchanger for a vehicle air conditioner, since the dimensions and shapes of the external piping to be connected vary depending on the applicable vehicle type, it is possible to perform an airtight inspection on the heat exchanger core alone before connecting the external piping. The benefits you can do are great. Specifically, in addition to the merit of downsizing the brazing furnace and the airtightness inspection machine, the merit of saving the core storage space and improving the core transportation efficiency after the airtightness inspection is also great.

このように本発明の熱交換器によれば、低い加工コストで外部配管等の無駄な廃棄を回避し、かつ気密検査用設備やろう付け炉を小型化することができる。とくに車両空調装置用熱交換器のように、接続される外部配管の寸法や形状が適用対象ごとに大きく異なる場合には、かかる小型化のメリットは大きい。   As described above, according to the heat exchanger of the present invention, it is possible to avoid wasteful disposal of external piping and the like at a low processing cost, and to reduce the size of an airtight inspection facility and a brazing furnace. In particular, when the size and shape of the external piping to be connected vary greatly depending on the application target, such as a heat exchanger for a vehicle air conditioner, the merit of such downsizing is great.

By being joined to the left and right surfaces of the block-shaped member 17 in the form, the internal passage 9 is closed to the outside. The first plate-like member 15 is provided with openings 8 for inlets and outlets, and these openings 8 are formed so as to come to the positions of the internal passages 9 for inlets and outlets by joining, respectively. Yes. Since the opening 8 is not formed in the second plate member 16, the internal passage 9 is completely closed to the outside on the joint surface side of the second plate member 16.
