Claim 10:
11. The heat exchanger according to claim 1, wherein the collecting pipe is placed horizontally and has a length greater than 250 mm; the collecting pipe is a round pipe and a diameter of the collecting pipe is larger than a width of the heat exchange tube; the collecting pipe comprises a first end, a second end and an outer peripheral surface; a distance between the first end of the heat exchange tube and the second surface of the baffle adjacent to the second cavity is greater than 0 mm and less than or equal to 2 mm;
wherein the heat exchanger further comprises:
fins disposed between adjacent heat exchange tubes, the fins being at least partially connected to the heat exchange tubes;
a distribution pipe having a first end, a second end, a pipe wall, an inner space and an outer peripheral surface; the first end of the distribution pipe being a fluid inlet; the second end of the distribution pipe being closed and extending into the second cavity from the first end of the collecting pipe; a length of the distribution pipe extending into the second cavity being substantially the same as a length of the collecting pipe; the pipe wall of the distribution pipe defining a plurality of through holes disposed along a length direction of the distribution pipe; the through holes being in communication with the second cavity and the inner space of the distribution pipe; the through holes being opened at any position of the distribution pipe along a circumferential direction of the distribution pipe; and
a support assembly comprising a plurality of first supports and a second support; the plurality of first supports being disposed along the length direction of the collecting pipe; each of the first supports comprising a first end and a second end; the first end of the first support being connected with the outer peripheral surface of the collecting pipe; the second end of the first support passing through the pipe wall of the collecting pipe, the first cavity and the baffle in sequence from the outer peripheral surface of the collecting pipe and extending into the second cavity; the first support being located below the distribution pipe and being in contact with the outer peripheral surface of the distribution pipe; the second support extending into the second cavity from the second end of the collecting pipe; the second support being located below the distribution pipe and being in contact with the outer peripheral surface of the distribution pipe.
