Title
(EN) FINNED HEAT EXCHANGER AND METHOD OF MANUFACTURING THE SAME
(FR) ECHANGEUR DE CHALEUR A AILETTES ET SON PROCEDE DE PRODUCTION
(JA) フィン付き熱交換器およびその製造方法
Abstract
(EN) A finned heat exchanger, comprising a front side heat exchanger (20) and a rear side heat exchanger (40). Each of the front side heat exchanger and the rear side heat exchanger further comprises a large number of fins (21, 41) arranged parallel with each other at specified intervals and a large number of heat transfer tubes (11) inserted into the fins generally perpendicular to the fins and allowing refrigerant to flow therein. The fins of the front side heat exchanger are so formed that each of the upstream side leading edge (22, 23) thereof and the downstream side trailing edge (32, 33) thereof is formed in bent shapes by two straight line parts forming a same obtuse angle and a curved part line part (24, 34) connecting these two straight lines to each other, and that a distance (B) between the upstream side leading edge and the downstream side trailing edge in an area near a once-through blower (5) among two areas held by the linear upstream side leading edge and the linear downstream side trailing edge of the fins is made shorter than a distance (A) between the upstream side leading edge and the downstream side trailing edge in an area apart from the once-through blower.
(FR) L'invention concerne un échangeur de chaleur à ailettes, comprenant un échangeur de chaleur côté avant (20) et un échangeur de chaleur côté arrière (40) qui présentent chacun un grand nombre d'ailettes (21, 41), agencées de manière parallèle les unes aux autres à des intervalles spécifiés, ainsi qu'un grand nombre de tubes de transfert de chaleur (11) insérés dans les ailettes de manière généralement perpendiculaire à ces dernières et permettant au réfrigérant de s'écouler à l'intérieur. Les ailettes de l'échangeur de chaleur côté avant sont formées de sorte que: chacun de leur bord avant côté amont (22, 23) et chacun de leur bord arrière côté aval (32, 33) présentent une forme courbée et comprennent deux parties rectilignes formant un même angle obtus et une partie incurvée (24, 34) reliant ces deux parties rectilignes; et une distance (B) entre le bord avant côté amont et le bord arrière côté aval dans une zone située à proximité d'une soufflante à passage unique (5), sélectionnée parmi deux zones formées par le bord avant linéaire côté amont et le bord arrière linéaire côté aval des ailettes, est inférieure à une distance (A) entre le bord avant côté amont et le bord arrière côté aval dans une zone éloignée de la soufflante à passage unique.
(JA) フィン付き熱交換器は、前面側熱交換器(20)および背面側熱交換器(40)はそれぞれ所定の間隔で平行に並べられた多数のフィン(21,41)と、これら各フィンに略直角に挿入されて内部を冷媒が流動する多数の伝熱管(11)とから構成されている。前記前面側熱交換器におけるフィンは、その風上前縁(22,23)および風下後縁(32,33)がそれぞれが同じ鈍角をなす2本の直線部並びにこれら2本の直線の間を結ぶ1本の曲線部(24,34)により折曲状に形成されるとともに、このフィンの直線状の風上前縁と直線状の風下後縁とで挟まれた二つの領域のうち、貫流送風機(5)に近い側の領域における風上前縁と風下後縁との距離(B)が、貫流送風機から遠い側の領域における風上前縁と風下後縁との距離(A)よりも短くされいる。
