図１は、本発明の実施例を示しており、コンデンサ１にレシーバドライヤ１０を一体にした組立体の例を示す。
コンデンサ１は、２本の冷媒通路２，３を有し、コンデンサ１の開口部４にはレシーバドライヤ１０の胴体１００の端部と継手部１１０が挿入され、コンデンサ１の開口部４と胴体１００の端部の間は、Ｏリング５でシールされる。コンデンサ１に対してレシーバドライヤ１０はこの実施例では取付金具７で固着される。 FIG. 1 shows an embodiment of the present invention, and shows an example of an assembly in which a receiver dryer 10 is integrated with a capacitor 1.
The capacitor 1 has two refrigerant passages 2 and 3, and the end portion of the body 100 of the receiver dryer 10 and the joint portion 110 are inserted into the opening 4 of the capacitor 1, and the opening 4 and the body 100 of the capacitor 1 are inserted. Is sealed with an O-ring 5. In this embodiment, the receiver dryer 10 is fixed to the capacitor 1 with a mounting bracket 7.

レシーバドライヤ１０は、金属材を加工した円筒状の胴体１００と、胴体１００の開口端側に形成される継手部１１０を有する。胴体１００の内部には、乾燥剤１２０が充填され、不織布等でつくられるフィルタ１３０が挿入される。フィルタ１３０の反対側にはパンチングメタル等でつくられる補強板１４０が挿入され、ノッチ又はスピニング加工部Ｋ１で固定される。 The receiver dryer 10 includes a cylindrical body 100 obtained by processing a metal material, and a joint portion 110 formed on the opening end side of the body 100. The body 100 is filled with a desiccant 120 and a filter 130 made of a nonwoven fabric or the like is inserted. On the opposite side of the filter 130 is inserted reinforcing plate 140 made of punching metal or the like, it is fixed in a notch or spinning unit K 1.

レシーバドライヤ１０の継手部１１０は、先細りのテーパー形状に形成されてテーパー面を有している。継手部１１０の先端の開口部には、プラスチック材を一体成型して作られるストレーナ１５０が取付けられ、ストレーナ１５０は通過して流出する冷媒中の異物の通過を防ぐ。継手部１１０のテーパー面には、冷媒が流入する穴１１２が形成される。   The joint portion 110 of the receiver dryer 10 is formed in a tapered shape having a taper surface. A strainer 150 made by integrally molding a plastic material is attached to the opening at the tip of the joint portion 110, and the strainer 150 prevents passage of foreign substances in the refrigerant that passes through and flows out. A hole 112 through which the refrigerant flows is formed in the tapered surface of the joint portion 110.

図２は、本発明の実施例に係るレシーバドライヤ１０の胴体１００の先端の継手部１１０を、コンデンサ１に対して組付けるための構造を拡大して示す。
レシーバドライヤ１０の継手部１１０は、絞り加工により成形される先細りのテーパー面１１１を有し、テーパー面１１１に冷媒通過用の穴１１２が設けられる。テーパー面１１１の先端部は首部１１９を有している。この首部１１９の開口部の内径は胴体１００の内径よりも小さくなっており、首部１１９にはストレーナ１５０の小径側の円筒部１５１が圧入等の方法によって固着されている。 FIG. 2 shows an enlarged structure for assembling the joint portion 110 at the tip of the body 100 of the receiver dryer 10 according to the embodiment of the present invention to the capacitor 1.
The joint portion 110 of the receiver dryer 10 has a tapered surface 111 that is formed by drawing, and the tapered surface 111 is provided with a hole 112 for passage of refrigerant. The tip of the tapered surface 111 has a neck 119. The inner diameter of the opening of the neck portion 119 is smaller than the inner diameter of the body 100, and a cylindrical portion 151 on the small diameter side of the strainer 150 is fixed to the neck portion 119 by a method such as press fitting.

ここで、ストレーナ１５０の形状例について図３と図４を参照して説明すると、ストレーナ１５０は、円筒部１５１と、円筒部１５２およびメッシュ部１５４を有しており、樹脂を成型することにより一体に製作されている。図示例では、円筒部１５１の外形寸法は円筒部１５２の外形寸法に比べて小さく、メッシュ部１５４の外形はさらに小さい。冷媒は、図２に示す冷媒通路２と穴１１２を通り、メッシュ部１５４を通って異物が除去された後に、円筒部１５１と円筒部１５２の中を通って、冷媒通路３側に戻る。
ストレーナ１５０の大径側の円筒部１５２は、コンデンサ１の冷媒の冷媒通路３に通ずる開口部４の下部開口部分４９内に圧入されている。この円筒部１５２の圧入により、冷媒の流入通路である冷媒通路２と、流出通路である冷媒通路３の間が確実にシールされている。 Here, an example of the shape of the strainer 150 will be described with reference to FIGS. 3 and 4. The strainer 150 has a cylindrical portion 151, a cylindrical portion 152, and a mesh portion 154, and is integrally formed by molding a resin. It is made in. In the illustrated example, the outer dimensions of the cylindrical portion 151 are smaller than the outer dimensions of the cylindrical portion 152, and the outer shape of the mesh portion 154 is smaller. The refrigerant passes through the refrigerant passage 2 and the hole 112 shown in FIG. 2, passes through the mesh portion 154, removes foreign matter, passes through the cylindrical portion 151 and the cylindrical portion 152, and returns to the refrigerant passage 3 side.
The cylindrical portion 152 on the large diameter side of the strainer 150 is press-fitted into the lower opening portion 49 of the opening 4 that communicates with the refrigerant passage 3 of the refrigerant of the condenser 1. By the press-fitting of the cylindrical portion 152, the gap between the refrigerant passage 2 that is the refrigerant inflow passage and the refrigerant passage 3 that is the outflow passage is reliably sealed.

また、コンデンサ１の開口部４の内面形状は、環状の溝２９を備える。この環状の溝２９は、レシーバドライヤ１０の胴体１００の一部分とコンデンサ１の開口部４の内面形状の間をシールするＯリング５を受け入れる空間を区画する。このＯリング５により、冷媒通路２からコンデンサ１の開口部４内に流入する冷媒が、円筒部１１７の外周部を通ってコンデンサ１の外に漏出することを確実に防止でき、コンデンサ１の開口部４と外部との間のシールをしている。   Further, the inner surface shape of the opening 4 of the capacitor 1 includes an annular groove 29. The annular groove 29 defines a space for receiving the O-ring 5 that seals between a part of the body 100 of the receiver dryer 10 and the inner shape of the opening 4 of the capacitor 1. The O-ring 5 can reliably prevent the refrigerant flowing from the refrigerant passage 2 into the opening 4 of the capacitor 1 from leaking out of the capacitor 1 through the outer peripheral portion of the cylindrical portion 117. A seal is provided between the portion 4 and the outside.

次に、図５と図６を参照して本発明の別の実施例について説明する。
図５と図６の実施例が図１と図２の実施例と異なるのは、レシーバドライヤ１０の継手部１１０の形状とＯリング５の取り付け構造である。
胴体１００とテーパー面１１１の間には、段付部１１６と、胴体１００に比べて縮径加工された円筒部１１７が形成される。そして、円筒部１１７の外周部には、シール部材であるＯリング５が嵌装される。レシーバドライヤ１０の継手部１１０の外面形状とコンデンサ１の開口部４の内面形状は、両者間をシールするＯリング５を受け入れる空間を区画すべく段付穴５ｂを備える。つまり、コンデンサ１には、このＯリング５を受け入れるための段付穴５ｂが加工される。この段付穴５ｂを設けることにより、Ｏリングを受け入れる環状の溝を省略することができ、加工コストが削減される。このＯリング５により、冷媒通路２から流入する冷媒が円筒部１１７の外周部を通ってコンデンサ１の外に漏出することが防止される。
なお、胴体１００をコンデンサ１側へ固定する取付金具７の構成は、種々のものが採用できる。 Next, another embodiment of the present invention will be described with reference to FIGS.
The embodiment of FIGS. 5 and 6 differs from the embodiment of FIGS. 1 and 2 in the shape of the joint 110 of the receiver dryer 10 and the mounting structure of the O-ring 5.
Between the body 100 and the tapered surface 111, a stepped portion 116 and a cylindrical portion 117 whose diameter is reduced as compared with the body 100 are formed. An O-ring 5 that is a seal member is fitted on the outer peripheral portion of the cylindrical portion 117. The outer surface shape of the joint portion 110 of the receiver dryer 10 and the inner surface shape of the opening 4 of the capacitor 1 include a stepped hole 5b so as to define a space for receiving the O-ring 5 that seals between the two. That is, the capacitor 1 is processed with a stepped hole 5b for receiving the O-ring 5. By providing the stepped hole 5b, an annular groove for receiving the O-ring can be omitted, and the processing cost is reduced. The O-ring 5 prevents the refrigerant flowing from the refrigerant passage 2 from leaking out of the capacitor 1 through the outer peripheral portion of the cylindrical portion 117.
Various configurations can be employed for the mounting bracket 7 for fixing the body 100 to the capacitor 1 side.
