Title (EN) HEAT EXCHANGER AND MANUFACTURING METHOD THEREFOR
(FR) ÉCHANGEUR DE CHALEUR ET PROCÉDÉ DE FABRICATION ASSOCIÉ
(JA) 熱交換器及びその製造方法
Abstract:
(EN) The present invention provides a heat exchanger having excellent hydrophilicity and hydrophilic sustainability and a manufacturing method therefor. Provided are: a heat exchanger (1) that is provided with a metal pipe (2), an aluminum fin (3), and a brazed part (4) where the metal pipe (2) and the aluminum fin (3) are joined; and a manufacturing method therefor. In the X-ray fluorescence spectrum of the fin (3), an Si-derived peak intensity (ISi), a Zr-derived peak intensity (IZr), an F-derived peak intensity (IF), and an Al-derived peak intensity (IAl) satisfy a predetermined relationship. The fin (3) has a predetermined high-content section in the range from the surface thereof to a depth of 100 nm.
(FR) La présente invention concerne un échangeur de chaleur ayant un caractère hydrophile et une durabilité hydrophile excellents et son procédé de fabrication. L'invention concerne : un échangeur de chaleur (1) qui est pourvu d'un tuyau métallique (2), d'une ailette en aluminium (3) et d'une partie brasée (4) où le tuyau métallique (2) et l'ailette en aluminium (3) sont joints ; et son procédé de fabrication. Dans le spectre de fluorescence X de l'ailette (3), une intensité de pic dérivée de Si (ISi), une intensité de pic dérivée de Zr (IZr), une intensité de pic dérivée de F (IF) et une intensité de crête dérivée d'Al (IAl) satisfont une relation prédéfinie. L'ailette (3) a une section de haute-teneur prédéfinie dans la plage allant de sa surface à une profondeur de 100 nm.
(JA) 親水性及び親水持続性に優れた熱交換器及びその製造方法を提供する。金属管(2)と、アルミニウム製のフィン(3)と、これらが接続されたろう付け部(4)とを備える熱交換器(1)及びその製造方法である。フィン(3)の蛍光X線スペクトルにおいては、Si由来のピーク強度(ISi)と、Zr由来のピーク強度(IZr)と、F由来のピーク強度(IF)と、Al由来のピーク強度(IAl)とが所定の関係を満足する。フィン(3)は、その表面から深さ100nmまでの範囲内に所定の高含有部を有する。
