定構造である。<Means for Solving the Problem> The present invention has been devised to solve the above-mentioned problems, drawbacks, and inconveniences that have not been solved in the related art. And install them in parallel,
The refrigerant pipe is bent in a meandering manner to form a bend portion, and a fixing structure of the refrigerant pipe and the side plate for fixing the bend portion to the side plate, wherein the side plate has both ends of an elongated hole portion into which the bend portion is inserted. Open a substantially U-shaped insertion hole with a series of short holes at right angles to
This is a structure for fixing a refrigerant pipe and a side plate in which the width of the opening at the tip of the short hole facing the long hole is made slightly smaller than the outer diameter of the refrigerant pipe.

管部分を強く保持することになる。In this case, since the opening width of the tip portion of the short hole portion facing the long hole portion is made slightly smaller than the outer diameter of the refrigerant pipe, the tip portion of the short hole portion is fixed when the two refrigerant pipe portions are fixedly mounted. Although it will be forced to elastically deform to some extent, after mounting, the tip portion of the short hole portion strongly holds the two refrigerant pipe portions by the so-called springback effect.
〈実施例〉 以下本考案を実施例の図面に基いて説明する。<Embodiment> The present invention will be described below with reference to the drawings of an embodiment.
熱交換器の主体部分は、フロンガス等の冷媒が流れる
長尺な冷媒管１に、多数のフィン２を一定間隔で平行に
装着し、冷媒管１をＵ字型に曲げて蛇行状に連続させ、
Ｕ字型に曲げた部分をベンド部３とするものである。In the main part of the heat exchanger, a large number of fins 2 are attached in parallel to a long refrigerant pipe 1 through which a refrigerant such as CFC gas flows at regular intervals, and the refrigerant pipe 1 is bent in a U-shape to be continuous in a meandering shape. ,
The bent portion 3 is a portion bent into a U shape.

を強く保持することになる。Therefore, first, as shown in FIG. 3, the bend portion 3 is inserted into the elongated hole portion 6 of the insertion hole 5, and further, as shown in FIG.
The refrigerant pipe 1 portion of the bend portion 3 is relatively laterally displaced and press-fitted into the short hole portion 7. At this time, since the opening width of the tip portion of the short hole portion 7 is slightly smaller than the outer diameter of the refrigerant pipe 1, the tip portion of the short hole portion 7 is pushed and expanded.
After the refrigerant pipe 1 portion has passed, it elastically returns, and the tip portion of the short hole portion 7 strongly holds the two refrigerant pipe portions by the springback effect.
図示実施例では、短孔部７の先端部分の開口部幅は、
長孔部６との連設部で特にやや小さくなっていて、横へ
の圧入時に抵抗の強いものになっている。In the illustrated embodiment, the opening width of the tip portion of the short hole portion 7 is
The connecting portion with the long hole portion 6 is particularly small in size, and has a strong resistance when laterally press-fitted.
