Claim 19:
20. A heat exchanger, comprising:
a manifold extending along a transverse direction, the manifold defining an inner cavity; the manifold comprising a pipe wall defining a plurality of insertion holes which are disposed along the transverse direction;
a baffle disposed in the inner cavity of the manifold, the baffle extending along the transverse direction of the manifold so as to separate the inner cavity of the manifold into a first cavity and a second cavity, the baffle defining a plurality of slots which are disposed along an extending direction of the baffle, the plurality of slots and the plurality of insertion holes being disposed in a one-to-one correspondence manner, the plurality of slots extending through the baffle along a vertical direction perpendicular to the transverse direction;
a plurality of heat exchange tubes connecting with the manifold and extending along the vertical direction, the heat exchanger tubes arranged at intervals along the transverse direction, each heat exchange tube extending through a corresponding insertion hole and a corresponding slot so that a first end of each heat exchange tube is inserted into the second cavity, and at least part of each heat exchange tube is disposed in the first cavity; each heat exchange tube defining a row of micro-channels in communication with the second cavity of the manifold; and
a distribution pipe comprising a first portion located in the second cavity of the manifold and a second portion located outside the manifold; the first cavity being separated from the distribution tube by the baffle along the vertical direction; the second portion of the distribution pipe defining a fluid inlet, the first portion defining a chamber being in communication with the fluid inlet; the first portion defining a plurality of through holes communicated with the second cavity and the chamber;
the plurality of through holes comprising a first through hole, a second through hole, a third through hole, . . . an (n−1)th through hole and an nth through hole in sequence along the transverse direction from an end of the first portion close to the second portion to an end of the first portion away from the second portion; wherein a value of n is an integer greater than or equal to five;
wherein an (i+1)th through hole and an ith through hole satisfy a relationship: di=L0, i=1, 2, . . . n−1, α=0.618;
wherein di represents a distance between the (i+1)th through hole and the ith through hole, and L0 represents a distance between adjacent heat exchange tubes.
