Title
(EN) HEAT EXCHANGER
(FR) ÉCHANGEUR DE CHALEUR
(JA) 熱交換器
Abstract
(EN)
A heat exchanger (20) has a heat-exchange tube (40) surrounded by a core case (30), and cools a first heat medium flowing inside the heat-exchange tube (40) by a second heat medium flowing inside the core cases (30) on the outer periphery of the heat-exchange tube (40). The heat-exchange tube (40) includes first and second heat-exchange tubes (41, 42) which are different types, and the amount of heat exchanged in the first heat-exchange tube (41) is set to be larger than the amount of heat exchanged in the second heat-exchange tube (42).
(FR)
L'invention concerne un échangeur de chaleur (20) doté d'un tube échangeur de chaleur (40), entouré par un boîtier de partie centrale (30), qui refroidit un premier fluide caloporteur s'écoulant à l'intérieur du tube d'échange de chaleur (40) par un second fluide caloporteur s'écoulant à l'intérieur du boîtier de partie centrale (30) sur la périphérie externe du tube échangeur de chaleur (40). Le tube échangeur de chaleur (40) comprend des premier et second tubes échangeurs de chaleur (41, 42) de différents types, et la quantité de chaleur échangée dans le premier tube échangeur de chaleur (41) est réglée pour être plus grande que la quantité de chaleur échangée dans le second tube échangeur de chaleur (42).
(JA)
熱交換器(20)は、コアケース(30)に熱交換チューブ(40)が囲われ、熱交換チューブ(40)の内部に流される第1熱媒体を、熱交換チューブ(40)の外周であってコアケース(30)の内部に流される第2熱媒体によって冷却する。熱交換チューブ(40)は、それぞれ種類の異なる第1熱交換チューブ(41)と、第2熱交換チューブ(42)と、を含み、第1熱交換チューブ(41)において行われる熱交換の熱量が、第2熱交換チューブ(42)において行われる熱交換の熱量よりも多くなるよう設定されている。
