Abstract:
(EN) A heat exchanger, comprising: a heat exchange pipe unit and a fin unit (400), wherein the heat exchange pipe unit comprises a refrigerant input pipe (100), a heat exchange pipe assembly (200) and a refrigerant output pipe (300); the refrigerant input pipe (100) is connected to one end of the heat exchange pipe assembly (200); the refrigerant output pipe (300) is connected to the other end of the heat exchange pipe assembly (200); the fin unit (400) is fixedly arranged outside of the heat exchange pipe assembly (200); the heat exchange pipe assembly (200) and the fin unit (400) are made of aluminum alloy; and the corrosion potential of the aluminum alloy which forms at least a part of the heat exchange pipe assembly (200) is greater than the corrosion potential of the aluminum alloy which forms the remaining part of the heat exchange pipe assembly (200).
(FR) L'invention concerne un échangeur de chaleur comprenant : un bloc de tuyaux à échange de chaleur et un ensemble ailette (400), le bloc de tuyaux à échange de chaleur comprenant un tuyau d'entrée de fluide frigorigène (100), un ensemble tuyau d'échange de chaleur (200) et un tuyau de sortie de fluide frigorigène (300); le tuyau d'entrée de fluide frigorigène (100) est relié à une extrémité de l'ensemble tuyau d'échange de chaleur (200); le tuyau de sortie de fluide frigorigène (300) est relié à l'autre extrémité de l'ensemble tuyau d'échange de chaleur (200); l'ensemble ailette (400) est disposé à demeure à l'extérieur de l'ensemble tuyau d'échange de chaleur (200); l'ensemble tuyau d'échange de chaleur (200) et l'ensemble ailette (400) sont en alliage d'aluminium; et le potentiel de corrosion de l'alliage d'aluminium formant au moins une partie de l'ensemble tuyau d'échange de chaleur (200) est supérieur au potentiel de corrosion de l'alliage d'aluminium formant la partie restante de l'ensemble tuyau d'échange de chaleur (200).
(ZH) 一种换热器，包括：换热管单元以及翅片单元（400），其中换热管单元包括制冷剂输入管（100）、换热管组件（200）以及制冷剂输出管（300），制冷剂输入管（100）与换热管组件（200）的一端相连，制冷剂输出管（300）与换热管组件（200）的另一端相连，翅片单元（400）固定设置在换热管组件（200）的外部，换热管单元（200）以及翅片单元（400）由铝合金形成，形成换热管组件（200）的至少一部分的铝合金的腐蚀电位，高于形成换热管组件（200）其余部分的铝合金的腐蚀电位。
