Title (EN) HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE
(FR) ÉCHANGEUR DE CHALEUR ET DISPOSITIF À CYCLE FRIGORIFIQUE
(JA) 熱交換器及び冷凍サイクル装置
Abstract:
(EN) The heat exchanger relating to the present invention is provided with: a plurality of heat transfer pipes that are disposed in the vertical direction at predetermined intervals; a tubular header having, on a side surface portion thereof, a plurality of connection sections, to which the heat transfer pipes are connected, said tubular header being in communication with the heat transfer pipes; a refrigerant pipe in communication with the header at a header middle portion in the vertical direction; and a first bypass pipe having one end that is in communication with a lower portion of the header, and the other end that is in communication with a middle portion of the refrigerant pipe. The distance between an inner wall of the header, and the position where the first bypass pipe and the refrigerant pipe are in communication with each other is within double the inner diameter of the refrigerant pipe.
(FR) L'invention concerne un échangeur de chaleur comprenant : une pluralité de tuyaux de transfert de chaleur qui sont disposés dans la direction verticale à des intervalles prédéfinis ; un collecteur tubulaire ayant, sur une partie surface latérale de celui-ci, une pluralité de sections de raccordement, auxquelles les tuyaux de transfert de chaleur sont raccordés, ledit collecteur tubulaire étant en communication avec les tuyaux de transfert de chaleur ; un tuyau de fluide frigorigène en communication avec le collecteur au niveau d'une partie centrale de collecteur dans la direction verticale ; et un premier tuyau de dérivation ayant une extrémité qui est en communication avec une partie inférieure du collecteur et l'autre extrémité qui est en communication avec une partie centrale du tuyau de fluide frigorigène. La distance entre une paroi interne du collecteur et la position dans laquelle le premier tuyau de dérivation et le tuyau de fluide frigorigène sont en communication l'un avec l'autre est dans la plage du double du diamètre interne du tuyau de fluide frigorigène.
(JA) 本発明に係る熱交換器は、上下方向に規定の間隔を空けて配置された複数の伝熱管と、側面部に前記伝熱管が接続された複数の接続箇所を有し、前記伝熱管のそれぞれと連通する管状のヘッダと、前記ヘッダにおける上下方向の途中部において、前記ヘッダと連通する冷媒配管と、一端が前記ヘッダの下部に連通し、他端が前記冷媒配管の途中部に連通する第1バイパス管と、を備え、前記第1バイパス管と前記冷媒配管との連通位置と前記ヘッダの内壁との間の距離が、前記冷媒配管の内径の2倍以内となっている。
