Title (EN) DOUBLE PIPE
(FR) TUYAU DOUBLE
(JA) 二重管
Abstract:
(EN) A double pipe (61) is provided with an inner pipe (62) inside of which a refrigerant flows, and an outer pipe (63) that has the inner pipe (62) in the interior thereof, the refrigerant flowing between the inner pipe (62) and the outer pipe (63). The inner pipe (62) has a pipe member (64) formed in the shape of a cylinder, and a helical member (65) disposed inside the pipe member (64). The helical member (65) has a helical part (66) that guides the flow of refrigerant flowing inside the inner pipe (62) into a helical shape, and a guide part (67) that is connected to a longitudinal-direction end (66a) of the helical part (66) and that guides the flow of the refrigerant flowing inside the inner pipe (62). The guide part (67) is formed so as to have less flow channel resistance than does the helical part (66).
(FR) Un tuyau double (61) est pourvu d'un tuyau interne (62) à l'intérieur duquel s'écoule un fluide frigorigène, et d'un tuyau externe (63) avec le tuyau interne (62) à l'intérieur de celui-ci, le fluide frigorigène s'écoulant entre le tuyau interne (62) et le tuyau externe (63). Le tuyau interne (62) a un élément de tuyau (64) formé sous la forme d'un cylindre, et un élément hélicoïdal (65) disposé à l'intérieur de l'élément de tuyau (64). L'élément hélicoïdal (65) a une partie hélicoïdale (66) qui guide l'écoulement de fluide frigorigène s'écoulant à l'intérieur du tuyau interne (62) en une forme hélicoïdale, et une partie de guidage (67) qui est reliée à une extrémité de direction longitudinale (66a) de la partie hélicoïdale (66) et qui guide l'écoulement du fluide frigorigène s'écoulant à l'intérieur du tuyau interne (62). La partie de guidage (67) est formée de manière à avoir une résistance de canal d'écoulement inférieure à celle de la partie hélicoïdale (66).
(JA) 二重管(61)は、冷媒が内部を流れる内管(62)と、内管(62)を内部に有し、冷媒が内管(62)との間を流れる外管(63)と、を備える。内管(62)は、円筒形に形成される管部材(64)と、管部材(64)の内部に配される螺旋部材(65)と、を有する。螺旋部材(65)は、内管(62)の内部を流れる冷媒の流れを螺旋状に案内する螺旋部(66)と、螺旋部(66)の長手方向の端部(66a)に接続され、内管(62)の内部を流れる冷媒の流れを案内するガイド部(67)と、を有する。ガイド部(67)は、螺旋部(66)と比較して流路抵抗が小さくなるように形成される。
