Abstract
(EN)
Disclosed in the present application is a heat exchanger. The heat exchanger comprises a collecting pipe, heat exchange pipes, and a distribution pipe. There are a plurality of heat exchange pipes, a first end of each heat exchange pipe penetrates a pipe wall of the collecting pipe and is inserted into the collecting pipe, and the heat exchange pipes communicate with the collecting pipe. A first end of the distribution pipe is a fluid inlet, and a second end of the distribution pipe is closed and extends from the first end of the collecting pipe into the collecting pipe. A pipe wall of the distribution pipe has a plurality of through holes that communicate with the collecting pipe and the distribution pipe, and the plurality of through holes are a first through hole,... an n-1th through hole and an n-th through hole arranged successively along the direction from the first end to the second end of the distribution pipe, wherein the distance between an i+1th through hole and an ith through hole is: diiL0, i= 1,2,...n-1, α=0.618, L0, which is the distance between adjacent heat exchange pipes. The heat exchanger of the present application may improve the uniformity of refrigerant distribution in the heat exchanger.

La présente invention concerne un échangeur de chaleur. L'échangeur de chaleur comprend un tuyau de collecte, des tuyaux d'échange de chaleur et un tuyau de distribution. Il existe une pluralité de tuyaux d'échange de chaleur, une première extrémité de chaque tuyau d'échange de chaleur pénètre dans une paroi de tuyau du tuyau de collecte et est insérée dans le tuyau de collecte, et les tuyaux d'échange de chaleur communiquent avec le tuyau de collecte. Une première extrémité du tuyau de distribution est une entrée de fluide, et une seconde extrémité du tuyau de distribution est fermée et s'étend de la première extrémité du tuyau de collecte dans le tuyau de collecte. Une paroi de tuyau du tuyau de distribution comporte une pluralité de trous traversants qui communiquent avec le tuyau de collecte et le tuyau de distribution, et la pluralité de trous traversants sont un premier trou traversant, ..., un trou traversant n-1 et un n-ième trou traversant agencés successivement le long de la direction allant de la première extrémité à la seconde extrémité du tuyau de distribution, la distance entre un i +1ième trou traversant et un ième trou traversant étant : diiL0, i= 1,2,...n-1, α=0,618, L0, qui est la distance entre des tuyaux d'échange de chaleur adjacents. L'échangeur de chaleur de la présente invention peut améliorer l'uniformité de distribution de fluide frigorigène dans l'échangeur de chaleur.
