Title (EN) HEAT EXCHANGER AND HEAT PUMP SYSTEM
(FR) ECHANGEUR DE CHALEUR ET SYSTÈME DE POMPE À CHALEUR
(JA) 熱交換器およびヒートポンプシステム
Abstract: front page image
(EN)A heat exchanger having improved productivity and connection reliability while keeping corrosive resistance to water and a heat pump system are provided. The heat exchanger comprises a first flat-shaped tube (1) having first refrigerant flow passages through which a first refrigerant flows and a second flat-shaped tube (2) having second refrigerant passages through which water serving as a second refrigerant flows and being constituted of a metal having the corrosive resistance to the water. The second flat-shaped tube (2) has rectangular tubes. The joining part between the flat surface of the first flat-shaped tube (1) and the flat surface of the second flat-shaped tube (2), and the joining part between the rectangular tubes are brazed simultaneously.
(FR)L'invention concerne un échangeur de chaleur dont la productivité et la fiabilité des connexions sont améliorées, et dont la résistance à la corrosion due à l'eau est maintenue, ainsi qu'un système de pompe à chaleur. L'échangeur de chaleur est constitué d'un premier tube plat (1) ayant des premiers passages d'écoulement destinés à un premier réfrigérant, et d'un second tube plat (2) ayant des seconds passages d'écoulement destinés à la circulation de l'eau, qui sert de second réfrigérant. Ces tubes sont composés d'un métal résistant à la corrosion provoquée par l'eau. Le second tube plat (2) présente des tubes rectangulaires. La partie de jointure entre la surface plane du premier tube plat (1) et la surface plane du second tube plat (2) ainsi que la partie de jointure entre les tubes rectangulaires sont brasées simultanément.
(JA) 本発明は、水に対する耐食性を確保しながら、生産性および接合信頼性を向上する熱交換器およびヒートポンプシステムを提供することを目的としている。  この発明に係る熱交換器は、第1冷媒が流れる第1冷媒流路を複数有する扁平状の第1扁平管1と、第2冷媒である水が流れる第2冷媒流路を有し、水に対して耐食性を有する金属で構成される扁平状の第2扁平管2とを備え、前記第2扁平管2は、複数の矩形状の矩形管を有し、前記第1扁平管1の扁平面と前記第2扁平管2の扁平面との間である扁平管接合部および前記複数の矩形管の間である矩形管接合部を同時にろう付けするものである。
