Description

【０００１】
【発明の属する技術分野】
本発明は、自動車用の空調装置等に使用される冷媒を貯溜すると共に、冷媒中の水分を除去するためのレシーバドライヤに関する。
【０００２】
【従来の技術】
例えば、特開２０００−２２１５４２号公報は、この種のレシーバドライヤを示す。レシーバドライヤは、アルミ合金材を円筒状に形成した本体と、本体の開口部を封止するヘッダと称する円盤状の部材を備える。本体内部には、冷媒中の水分を吸収する乾燥剤が封入される。乾燥剤は粒状のものであって、乾燥剤を支持するためにプラスチック製の不織布によるフィルタと、フィルタを支持するメッシュ金属製の支持部材等を必要とする。ヘッダには、冷媒の入口穴と出口穴が設けられ、空調装置の他の部材に連通される。
【０００３】
【発明が解決しようとする課題】
本発明は、以上のような基本的な構成を有するレシーバドライヤの構成を簡素化し、小型で軽量のレシーバドライヤを提供するものである。
【０００４】
【課題を解決するための手段】
本発明によるレシーバドライヤは、空気調和装置に使用される冷媒を貯留するとともに該冷媒中の水分を除去する機能を有するレシーバドライヤであって、有底の円筒状の本体と、該本体の開口部に固着され冷媒の入口穴及び出口穴を有する円盤状のヘッダと、前記本体内に封入される乾燥剤と、前記出口穴に取り付けられる異物除去用のストレーナとを備え、前記入口穴は、前記ヘッダの外側の端面から前記本体の内部に向けて延びるとともに先端部が前記ヘッダの側面に開口するように形成されており、前記ヘッダの側面における前記入口穴の開口が形成された部位と前記本体の内周面との間に冷媒が通過する隙間が形成されていることを特徴とする。
【０００５】
さらに、本発明のレシーバドライヤにおいて、前記ストレーナは、メッシュ状の金属円板をドーム状に加工してなるもので、前記ヘッダの内側の端面に前記本体の内部に向けて凸となるように取り付けられていることを特徴とする。
【０００６】
そして、本体とヘッダ又は蓋部材は、アルミ合金でつくられ、本体の開口部に固着されるヘッダ又は蓋部材の固着手段は、アーク溶接手段である。
【０００７】
【発明の実施の形態】
図１は、本発明の実施の形態の第１の例を示す説明図、図２はその構成を示す部品図である。全体を符号１００で示すレシーバドライヤは、円筒状のタンクである本体１１０と、本体１１０の開口部１１２を封止する円盤状のヘッダ１２０を有する。本体１１０の開口部１１２の反対側の底部１１４は、厚肉部に形成され、剛性の向上が図られる。
【０００８】
図２に示すように、本体１１０（図２（ａ）に示す）内に封入されるバッグ１３０（図２（ｂ）に示す）は、例えば、プラスチック製の不織布を折りたたんで、その周辺１３２ａ，１３２ｂ，１３２ｃを熱シール又は縫合してバッグ状に形成した構造を有する。バッグ１３０内には、乾燥剤１３４が封入される。バッグ１３０は、液体が通過しうる間隙を有するプラスチック製の不織布でつくられるので、本体１１０内に貯溜される冷媒は、バッグ１３０内の乾燥剤１３４に接触して、冷媒中に含まれる水分が乾燥剤に吸着される。
【０００９】
ヘッダ１２０（図２（ｄ）に示す）の本体１１０内に対向する端面には、薄肉の壁部１２６が形成される。この薄肉の壁部１２６の内側において、出口穴１２４が、ヘッダ１２０の本体１１０内に対向する端面に開口している。この壁部１２６の内部には、ストレーナ１４０（図２（ｃ）に示す）が挿入され、カシメ加工部Ｋ１によりヘッダ１２０に固定される。
このストレーナ１４０は、メッシュ金属円板を中高状に加工したものであって、本体１１０から出口穴１２４に向かう冷媒中の異物を除去する機能を有する。
【００１０】
このレシーバドライヤ１００の組立に際しては、本体１１０内にバッグ１３０を封入し、本体１１０の開口部１１２にヘッダ１２０を挿入し、アーク溶接加工Ｗ１により接合を行なう。
ヘッダ１２０には、予めストレーナ１４０がカシメ加工部Ｋ１により取付けられている。
このレシーバドライヤ１００は、冷媒の入口穴１２２、出口穴１２４が下方を向く姿勢で空調システム内に装備される。
入口穴１２２は、ヘッダ１２０の外側の端面１２７から本体１１０の内部に向けて延びているが、入口穴１２２の先端部１２２ａはヘッダ１２０の側面１２８に開口するように形成されている。また、入口穴１２２の先端部１２２ａがヘッダ１２０の側面１２８において開口する部位と本体１１０の内周面１１１との間に冷媒が通過する隙間１２９が形成されている。したがって、入口穴１２２から流入した冷媒は、隙間１２９を通じて本体１１０の上方内部に送られ、出口穴１２４に流入しにくくなっている。
【００１１】
【発明の効果】
本発明のレシーバドライヤは、円筒状の本体内に乾燥剤を封入したバッグを自由状態で封入した構造を備える。バッグの支持構造を有しないので構造も簡素化され、また、部品点数も低減される。

BACKGROUND OF THE INVENTION
The present invention relates to a receiver dryer for storing a refrigerant used in an air conditioner or the like for an automobile and removing water in the refrigerant.
[0002]
[Prior art]
For example, Japanese Patent Laid-Open No. 2000-221542 shows this type of receiver dryer. The receiver dryer includes a main body in which an aluminum alloy material is formed in a cylindrical shape, and a disk-shaped member called a header that seals an opening of the main body. A desiccant that absorbs moisture in the refrigerant is sealed inside the main body. The desiccant is granular and requires a plastic non-woven fabric filter and a mesh metal support member for supporting the filter in order to support the desiccant. The header is provided with an inlet hole and an outlet hole for the refrigerant, and communicates with other members of the air conditioner.
[0003]
[Problems to be solved by the invention]
The present invention simplifies the configuration of the receiver dryer having the basic configuration as described above, and provides a small and lightweight receiver dryer.
[0004]
[Means for Solving the Problems]
A receiver dryer according to the present invention is a receiver dryer having a function of storing a refrigerant used in an air conditioner and removing moisture in the refrigerant, and has a bottomed cylindrical main body and an opening of the main body A disc-shaped header having a refrigerant inlet hole and an outlet hole fixed thereto, a desiccant sealed in the main body, and a foreign matter removing strainer attached to the outlet hole, A portion extending from the outer end surface of the header toward the inside of the main body and having a tip portion opened to the side surface of the header, and a portion where the opening of the inlet hole is formed on the side surface of the header and the main body A gap through which the refrigerant passes is formed between the inner peripheral surface of the first and second inner surfaces.
[0005]
Furthermore, in the receiver dryer of the present invention, the strainer is formed by processing a mesh-shaped metal disk into a dome shape, and is attached to the inner end face of the header so as to protrude toward the inside of the main body. It is characterized by being .
[0006]
The main body and the header or lid member are made of an aluminum alloy, and the fixing means for the header or lid member fixed to the opening of the main body is arc welding means.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an explanatory diagram showing a first example of an embodiment of the present invention, and FIG. 2 is a component diagram showing the configuration thereof. A receiver dryer generally indicated by reference numeral 100 has a main body 110 that is a cylindrical tank and a disc-shaped header 120 that seals an opening 112 of the main body 110. The bottom 114 on the opposite side of the opening 112 of the main body 110 is formed in a thick portion, and the rigidity is improved.
[0008]
As shown in FIG. 2, a bag 130 (shown in FIG. 2 (b)) enclosed in a main body 110 (shown in FIG. 2 (a)) is, for example, a plastic nonwoven fabric folded and its periphery 132 a, 132b and 132c are heat sealed or stitched to form a bag shape. A desiccant 134 is enclosed in the bag 130. Since the bag 130 is made of a plastic nonwoven fabric having a gap through which a liquid can pass, the refrigerant stored in the main body 110 comes into contact with the desiccant 134 in the bag 130, and the moisture contained in the refrigerant is reduced. Adsorbed on desiccant.
[0009]
A thin wall 126 is formed on the end surface of the header 120 (shown in FIG. 2D) facing the main body 110. Inside the thin wall portion 126, an outlet hole 124 opens on an end surface of the header 120 facing the main body 110. Inside the wall 126, a strainer 140 (shown in FIG. 2C) is inserted and fixed to the header 120 by the crimping portion K1.
The strainer 140 is obtained by processing a mesh metal disk into a medium-high shape, and has a function of removing foreign substances in the refrigerant from the main body 110 toward the outlet hole 124.
[0010]
When assembling the receiver dryer 100, the bag 130 is sealed in the main body 110, the header 120 is inserted into the opening 112 of the main body 110, and joining is performed by arc welding W1.
A strainer 140 is attached to the header 120 in advance by a crimping portion K1.
The receiver dryer 100 is installed in the air conditioning system so that the refrigerant inlet hole 122 and the outlet hole 124 face downward.
The inlet hole 122 extends from the outer end surface 127 of the header 120 toward the inside of the main body 110, but the distal end portion 122 a of the inlet hole 122 is formed to open to the side surface 128 of the header 120. Further, a gap 129 through which the refrigerant passes is formed between a portion where the front end portion 122 a of the inlet hole 122 opens on the side surface 128 of the header 120 and the inner peripheral surface 111 of the main body 110. Therefore, the refrigerant that has flowed from the inlet hole 122 is sent to the upper inside of the main body 110 through the gap 129 and is difficult to flow into the outlet hole 124.
[0011]
【The invention's effect】
The receiver dryer of the present invention has a structure in which a bag in which a desiccant is enclosed in a cylindrical main body is enclosed in a free state. Since there is no bag support structure, the structure is simplified and the number of parts is reduced.
