Title (EN) HEAT EXCHANGER AND HEAT EXCHANGING APPARATUS
(FR) ECHANGEUR DE CHALEUR ET APPAREIL ECHANGEUR DE CHALEUR
Abstract:
(EN) Disclosed is a heat exchanger and a heat exchanging apparatus that are capable of minimizing a loss of pressure of a heat transfer medium flowing in the heat exchanger while maintaining the heat conductivity improving effect by fins. The heat exchanger of the present invention is mainly constituted of a number of planar fins (14) parallelly arranged with spaces therebetween and a heat transfer tube (8) that is fixed on these planar fins (14) and forms a meandering form as an entire body. On the inner surface of straight tube portions (8A) that are located in the upstream portion GL of the heat transfer tubes (8), fins (24) are arranged in a form of zigzag to a circumference direction of the tube inner surface. On the other hand, on the inner surface of straight tube portions (8B) that are located in the downstream portion L (G) of the heat transfer tube (8), linear fins (28) that are parallel to the tube axis are formed.
(FR) L'invention concerne un échangeur de chaleur et un appareil échangeur de chaleur qui sont capables de réduire une perte de pression d'un agent de transfert de chaleur s'écoulant dans l'échangeur de chaleur tout en maintenant l'amélioration de la conductivité de chaleur par des nervures. L'échangeur de chaleur selon l'invention est principalement constitué d'un certain nombre de nervures plates (14) parallèles et espacées, et d'un tube de transfert de chaleur (8) fixé sur ces nervures plates (14) et formant un méandre en tant que corps entier. La surface interne de sections droites (8A) du tube, ces sections étant situées dans la section amont GL des tubes de transfert de chaleur (8), est pourvue de nervures (24) en zigzag dans une direction circonférentielle de la surface interne du tube. D'autre part, la surface interne des sections droites (8B) du tube, ces sections étant situées dans la section aval L (G) du tube de transfert de chaleur (8), est pourvue de nervures linéaires(28) parallèles à l'axe du tube.
