Claim 0:
1. A heat exchanger, comprising:
a collecting pipe having a first end, a second end, a pipe wall and an inner cavity;
a plurality of heat exchange tubes arranged along a length direction of the collecting pipe, each of the heat exchange tubes having a first end and an inner channel, the inner channel of the heat exchange tube being in communication with the inner cavity of the collecting pipe;
a distribution pipe having a first end, a second end, a pipe wall and an inner space, the first end of the distribution pipe being a fluid inlet, the second end of the distribution pipe being closed, the pipe wall of the distribution pipe defining a plurality of through holes which are in communication with the inner cavity of the collecting pipe and the inner space of the distribution pipe, the plurality of through holes being disposed along a length direction of the distribution pipe, and 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 a direction from the first end of the distribution pipe to the second end of the distribution pipe, wherein a value of n is an integer greater than or equal to five, a distance between an (i+1)th through hole and an ith through hole is:
di=αiL0, i=1, 2, . . . n−1, α=0.618, L0 is a distance between adjacent heat exchange tubes;
wherein the heat exchanger further comprises a support assembly comprising:
a first support having a first end and a second end, the collecting pipe having an outer peripheral surface, the distribution pipe having an outer peripheral surface, wherein the first end of the first support is connected to the outer peripheral surface of the collecting pipe and the second end of the first support is in contact with the outer peripheral surface of the distribution pipe such that, along a direction from the first end of the first support to the second end of the first support, the first support extends through the pipe wall of the collecting pipe and into the inner cavity of the collecting pipe; and
a second support extending from the second end of the collecting pipe into the inner cavity of the collecting pipe, and the second support being in contact with the outer peripheral surface of the distribution pipe.
