Title (EN) MICRO-CHANNEL HEAT EXCHANGER AND AIR-COOLED REFRIGERATOR
(FR) ÉCHANGEUR DE CHALEUR À MICRO-CANAL ET RÉFRIGÉRATEUR REFROIDI PAR AIR
(ZH) 微通道换热器及风冷冰箱
Abstract:
(EN) Provided are a micro-channel heat exchanger (100) and an air-cooled refrigerator. The micro-channel heat exchanger (100) comprises two collecting pipes (1), a plurality of heat exchange pipes (2) and at least one fin (3), the two collecting pipes (1) being arranged parallel to each other. Two ends of the plurality of heat exchange pipes (2) are connected to the two collecting pipes (1) respectively, the plurality of heat exchange pipes (2) bend along the lengthwise direction thereof to form a plurality of pipe layers (20), and the length of some of the heat exchange pipes (2) is smaller than that of the remaining heat exchange pipes (2). Each fin (3) is arranged between two adjacent pipe layers (20) or on the outside of the outermost pipe layer (20), and each fin (3) extends in a corrugated form in the extension direction of the heat exchange pipes (2). Each fin (3) extends continuously in the extension direction of the collecting pipes (1). The fin (3) is provided with a ventilation hole (33).
(FR) L'invention concerne un échangeur de chaleur à micro-canal (100) et un réfrigérateur refroidi par air. L'échangeur de chaleur à micro-canal (100) comprend deux tuyaux de collecte (1), une pluralité de tuyaux d'échange de chaleur (2) et au moins une ailette (3), les deux tuyaux de collecte (1) étant agencés parallèlement l'un à l'autre. Deux extrémités de la pluralité de tuyaux d'échange de chaleur (2) sont reliées respectivement aux deux tuyaux de collecte (1) , la pluralité de tuyaux d'échange de chaleur (2) se courbe le long de sa direction longitudinale pour former une pluralité de couches de tuyau (20), et la longueur de certains des tuyaux d'échange de chaleur (2) est inférieure à celle des tuyaux d'échange de chaleur restants (2). Chaque ailette (3) est disposée entre deux couches de tuyau adjacentes (20) ou sur l'extérieur de la couche de tuyau la plus à l'extérieur (20), et chaque ailette (3) s'étend sous une forme ondulée dans la direction d'extension des tubes d'échange de chaleur (2). Chaque ailette (3) s'étend en continu dans la direction d'extension des tuyaux de collecte (1). L'ailette (3) est pourvue d'un trou de ventilation (33).
(ZH) 提供了一种微通道换热器(100)和风冷冰箱。微通道换热器(100)包括:两个集流管(1)、多个换热管(2)和至少一个翅片(3),两个集流管(1)平行设置。多个换热管(2)的两端分别连接两个集流管(1),多个换热管(2)沿其长度方向弯折形成多个管层(20),部分换热管(2)的管长小于其余换热管(2)的管长。每个翅片(3)设在相邻两个管层(20)之间或设在最外层的管层(20)的外侧,在换热管(2)的延伸方向上每个翅片(3)呈波纹状延伸,在集流管(1)的延伸方向上每个翅片(3)连续延伸,翅片(3)上设有通风孔(33)。
