Abstract
(EN) A plate-type refrigerant piping has: a first plate (21); a second plate (22) layered on the first plate (21); a first brazing material (B1) for joining the first plate (21) and the second plate (22); a first connecting part (51) for connecting other refrigerant piping (101, 102), the first connecting part (51) being provided to the first plate (21); and a second brazing material (B2) for joining the other refrigerant piping (101, 102) to the first connecting part (51), the melting point of the first brazing material (B1) being higher than the melting point of the second brazing material (B2).
(FR) Une tuyauterie de réfrigérant de type à plaques comprend : une première plaque (21) ; une seconde plaque (22) empilée sur la première plaque (21) ; un premier matériau de brasage (B1) destiné à relier la première plaque (21) et la seconde plaque (22) ; une première partie de raccordement (51) destinée à raccorder une autre tuyauterie de réfrigérant (101, 102), la première partie de raccordement (51) étant disposée sur la première plaque (21) ; et un second matériau de brasage (B2) destiné à relier l'autre tuyauterie de réfrigérant (101, 102) à la première partie de raccordement (51), le point de fusion du premier matériau de brasage (B1) étant supérieur au point de fusion du second matériau de brasage (B2).
(JA) プレート型冷媒配管は、第１プレート（２１）と、第１プレート（２１）に積層される第２プレート（２２）と、第１プレート（２１）と第２プレート（２２）とを接合させる第１ろう材（Ｂ１）と、第１プレート（２１）に設けられ、他の冷媒配管（１０１，１０２）を接続するための第１接続部（５１）と、第１接続部（５１）に他の冷媒配管（１０１，１０２）を接合させる第２ろう材（Ｂ２）と、を有し、第１ろう材（Ｂ１）の融点が、第２ろう材（Ｂ２）の融点よりも高い。
