Abstract:
(EN) [Problem] To provide a heat exchanger which allows a refrigerant to flow uniformly without using a complex structure even with a configuration in which the refrigerant circulates through upward core portions and downward core portions. [Solution] Predetermined formulae are established from the relationship among the number of tubes 20, the total flow cross-sectional area of the tubes 20, the length in the header axial direction of the refrigerant circulation space of a header 10, the maximum cross-sectional area in the header radial direction of the refrigerant circulation space 10a of the header 10, and the minimum cross-sectional area in the header radial direction of the refrigerant circulation space 10a of the header 10 in a single upward core portion or a single downward core portion. The minimum and maximum shape coefficients of the upward core portion and the minimum and maximum shape coefficients of the downward core portion as calculated using the respective predetermined formulae fall within predetermined ranges. Thus, using the factors identifying the shape of the heat exchanger, it is possible to determine the shape of the heat exchanger such that the flow of a refrigerant is made uniform.
(FR) Le problème décrit par la présente invention est de fournir un échangeur de chaleur permettant l'écoulement uniforme d'un fluide frigorigène sans utiliser de structure complexe, même au moyen d'une configuration dans laquelle le fluide frigorigène circule dans des parties centrales vers le haut et des parties centrales vers le bas. La solution selon l'invention consiste à établir des formules prédéfinies à partir de la relation entre le nombre de tubes (20), la surface de la section transversale d'écoulement totale des tubes (20), la longueur, dans la direction axiale du collecteur, de l'espace de circulation de fluide frigorigène d'un collecteur (10), la surface de section transversale maximale, dans la direction radiale du collecteur, de l'espace de circulation de fluide frigorigène (10a) du collecteur (10), et la surface de section transversale minimale, dans la direction radiale du collecteur, de l'espace de circulation de fluide frigorigène (10a) du collecteur (10) dans une seule partie centrale vers le haut ou dans une seule partie centrale vers le bas. Les coefficients de forme minimaux et maximaux de la partie centrale vers le haut et les coefficients de forme minimaux et maximaux de la partie centrale vers le bas, calculés au moyen des formules prédéfinies respectives, s'inscrivent dans des plages prédéfinies. Ainsi, à l'aide des facteurs d'identification de la forme de l'échangeur de chaleur, il est possible de déterminer la forme de l'échangeur de chaleur de sorte que l'écoulement d'un fluide frigorigène soit uniforme.
(JA) 冷媒が上昇コア部と下降コア部とを流通する構成においても、複雑な構造を用いずに冷媒の流れを均一化することのできる熱交換器を提供する。 【課題】 【解決手段】一つの上昇コア部または下降コア部における、チューブ20の本数、チューブ20の総流路断面積、ヘッダー10の冷媒流通空間のヘッダー軸方向長さ、ヘッダー10の冷媒流通空間10aのヘッダー径方向最大断面積、ヘッダー10の冷媒流通空間10aのヘッダー径方向最小断面積の関係からなる所定の数式で求められる上昇コア部の形状係数の最小値及び最大値と、所定の数式で求められる下降コア部の形状係数の最小値及び最大値が所定範囲内になるようにしたので、熱交換器の形状を特定する因子により、冷媒の流れが均一になる熱交換器の形状を決めることができる。
