Title (EN) HEAT EXCHANGER
(FR) ÉCHANGEUR DE CHALEUR
(JA) 熱交換器
Abstract:
(EN) Provided is a heat exchanger with which adequate performance can be exhibited on both the upwind side and the downwind side in the airflow direction even when an increase in ventilation resistance due to the adhesion of frost is delayed, and with which the pressure resistance of flat multi-hole tubes is easily ensured. This heat exchanger is equipped with flat multi-hole tubes (63) having a plurality of channels (63b) aligned in the airflow direction, and fins (64) in which the flat multi-hole tubes (63) are inserted and secured in notches (64a) cut from the downwind side toward the upwind side in the airflow direction, and which have continuous parts (64x) joined at the top and bottom on the upwind side of the flat multi-hole tubes (63). In addition, the relationships 0.18 ≤ L/Wt ≤ 0.32 and 2 ≤ a/b ≤ 16 are satisfied, where L is the distance from the upwind end of the flat multi-hole tubes (63) to the upwind end of the fins (64) in the airflow direction, Wt is the length of the flat multi-hole tubes (63) in the airflow direction, a is the total value of the width in the airflow direction of the first and second channels (63b) from the upwind side in the flat multi-hole tubes (63), and b is the width in the airflow direction of the center channel (63b) in the airflow direction in the flat multi-hole tubes (63).
(FR) La présente invention concerne un échangeur de chaleur avec lequel une performance adéquate peut être présentée à la fois sur le côté sous le vent et le côté contre le vent dans la direction du flux d’air, même lorsqu’une augmentation de la résistance à la ventilation due à l’adhérence du givre est retardée, et avec lequel la résistance à la pression de tubes à trous multiples plats est aisément assurée. Cet échangeur de chaleur est équipé de tubes à trous multiples plats (63) comportant une pluralité de canaux (63b) alignés dans la direction du flux d’air, et d’ailettes (64) dans lesquelles les tubes à trous multiples plats (63) sont insérés et fixés dans des encoches (64a) découpées du côté sous le vent vers le côté contre le vent dans la direction du flux d’air, et qui comportent des parties continues (64x) assemblées au sommet et à la base sur le côté contre le vent des tubes à trous multiples plats (63). En outre, les relations 0,18 ≤ L/Wt ≤ 0,32 et 2 ≤ a/b ≤ 16 sont satisfaites, où L est la distance de l’extrémité contre le vent des tubes à trous multiples plats (63) à l’extrémité contre le vent des ailettes (64) dans la direction du flix d’air, Wt est la longueur des tubes à trous multiples plats (63) dans la direction du flux d’air, a est la valeur totale de la largeur dans la direction du flux d’air des premier et deuxième canaux (63b) depuis le côté contre le vent vers le haut dans les tubes à trous multiples plats (63), et b est la largeur dans la direction d’écoulement d’air du canal central (63b) dans la direction du flux d’air dans les tubes à trous multiples plats (63).
(JA) 霜の付着による通風抵抗の増大を遅らせる場合であっても、空気流れ方向における風上側と風下側の両方で十分に性能を発揮させつつ、扁平多穴管の耐圧強度を確保しやすい熱交換器を提供する。空気流れ方向に並んだ複数の通路(63b)を有する扁平多穴管(63)と、空気流れ方向の風下側から風上側に向けて切り欠かれた切り欠き部(64a)に扁平多穴管(63)が挿入固定されており、扁平多穴管(63)の風上側で上下に繋がった連通部(64x)を有するフィン(64)と、を備え、0.18≦L/Wt≦0.32であり、かつ、2≦a/b≦16の関係を満たす。ここで、L:扁平多穴管(63)の風上端からフィン(64)の風上端までの空気流れ方向の距離、Wt:扁平多穴管(63)の空気流れ方向の長さ、a:扁平多穴管(63)における風上側から1番目と2番目の通路(63b)の空気流れ方向の幅の合計値、b:扁平多穴管(63)における空気流れ方向中央の通路(63b)の空気流れ方向の幅である。
