本発明は異種金属からなるパイプを接続してなるパイプ
部材に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a pipe member formed by connecting pipes made of different metals.
例えば冷蔵庫において冷媒を循環させて冷凍サイクルを
構成するための７４イゾ部材は、熱伝導性が要求される
。For example, a 74 iso member for circulating a refrigerant in a refrigerator to configure a refrigeration cycle is required to have thermal conductivity.
一般に冷凍サイクル用のパイプ都拐は、ポンプに接続さ

パイプヲ使用して、このアルミニウムパイプの外表部に
アルマイト処理を旋して耐食性をもたせている。In general, pipes for refrigeration cycles use highly corrosion-resistant steel pipes for the part connected to the pump, and aluminum pipes, which have less corrosion resistance than copper but are cheaper, are used for other parts. The outer surface of this aluminum pipe is anodized to provide corrosion resistance.
しかして、銅パイプとアルミニウム・やイブとを接続す

めに信頼性９高いろうイ」けによる接合は行なえない。Therefore, it is necessary to connect the copper pipe and the aluminum pipe, but since both pipes are made of different metals, it is not possible to connect them with a highly reliable solder.
そこで、従来は第１図で示すよりにアルミニウム筒４と

う付は部６．６によシ接合している。Therefore, conventionally, as shown in FIG. 1, a joint 3 is used in which an aluminum tube 4 and a simple butt 5 are joined together by 7-butt adhesive, and an aluminum tube is attached to the aluminum tube 4 of this joint 3. In addition, copper wires 2 are joined to the steel portion 5 by brazing at portions 6 and 6, respectively.

を流れる冷媒が漏洩する虞れがある。However, in this conventional connection structure, the structure is complicated due to the use of the joint 3, and since brazing is performed twice, the connection operation is troublesome. Furthermore, the fludge-butt bonding that joins the aluminum cylinder 4 and the steel part 5 of the joint 3 is not reliable enough, and there is a risk that this joint will deteriorate and the refrigerant flowing through the pipe will leak.
本発明は前記事情に鑑みてなされたもので、異種金属か
らなるパイプを継手を用いずに簡単な構造および作業で
、しかも高い信頼性をもって接続したパイプ部材を提供
するものでおる。The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a pipe member in which pipes made of different metals are connected with simple structure and operation without using a joint, and with high reliability.

含むことができる。In the pipe member of the present invention, a metal layer made of the same metal as that of the other pipe is provided on the surface of the connecting portion of one pipe, and this metal layer and the other pipe are joined by brazing or the like. . The metal layer may be of any material as long as it can be easily bonded to the other i4 ino, and may include a combination such as a layer of a copper-based alloy or a copper pipe.
以下本発明を図面で示す一実施例について説明する。 An embodiment of the present invention illustrated in the drawings will be described below.

柑８を用いてろう伺けが旋されて接合されている。A layer 7 is provided on the outer surface of the aluminum via l in a groove shape over the entire length of the pipe. For this reason, the outer surface of the connecting portion of the aluminum tube 1 is provided with a gold H6 layer, that is, a copper layer 7 made of the same metal as the copper pipe 2 connected to the aluminum tube. The method of providing the copper layer 7 on the aluminum via 1 is by the Brad method, in which a copper pipe is fitted onto the outside of the aluminum, and the copper pipe is formed by extrusion or drawing, and then welded to the aluminum via under one pressure. Then, the connection part of the steel/mother pipe 2 is fitted to the connection part of the aluminum/mother pipe 1, that is, the outer circumference of the copper layer 7, and the open end of the copper pipe 2 and the copper N7 of the aluminum mother pipe 1 are The wax cover is twisted and joined using a wax material such as copper wax.
すなわち、銅・ぐイブ２と銅層７とは同質金属であるか
らろう付けが容易である。これＫよシアルミニウム・や
イブ１と銅層ぐイｆ２とが接続される。That is, since the copper guide 2 and the copper layer 7 are made of the same metal, brazing is easy. This connects the sia aluminum layer 1 and the copper layer f2.

わたって設けであるタメに、アルミニウム・母イブ１の
外表部全体を優れた耐食性をもって保強できる。In the connection between the aluminum glossy tube 1 and the copper pipe 2 configured in this way, both the pipes I and 2 are reliably joined by brazing, so the reliability and durability of the joint are high. The refrigerant flowing inside 2 is both mother Eve 1
．． There is no leakage from the joints of 2. Both pi f1.
The connection part 2 has a simple structure because it does not use a joint as in the conventional case, and it is easy to work because it requires only one brazing process. Moreover, since the copper layer 7 is provided not only at the connection portion of the aluminum via 1 but also over the entire length of the pipe, the entire outer surface of the aluminum mother tube 1 can be reinforced with excellent corrosion resistance.
従って、この実施例の・母イブ部材は冷凍サイクルを構

る。Therefore, the pipe member of the present invention is made of a different metal.
It is intended for those who connect the guive. It is preferable that the other pipe connected to one pipe has better corrosion resistance than the one pipe. The metal layer may be provided on one pipe only at the connection portion with the other pipe, but it is preferable to provide the metal layer over the entire length of the pipe. In addition to the cladding method, there are other methods for forming the gold layer, such as the plating method and the spraying method.
