Heat exchanger

A heat exchanger, comprising:

• a manifold extending along a transverse direction, the manifold comprising a wall and an inner cavity defined therein;
• a partition disposed in the inner cavity along the transverse direction to divide the inner cavity into a first cavity and a second cavity being not in communication with each other;
• and
• a plurality of heat exchange tubes connecting with the manifold and spaced apart from each other along the transverse direction, each of the heat exchange tubes defining a row of micro-channels to communicate with the second cavity, each of the heat exchange tubes extending along a vertical direction perpendicular to the transverse direction;
• a plurality of fins each disposed between adjacent heat exchange tubes, each heat exchange tube comprising a main body portion connecting with the fin and a first end portion extending from the main body portion to be inserted into the inner cavity;
• a distribution pipe inserted into the second cavity, the distribution pipe defining a plurality of through holes arranged along the transverse direction, each of the through holes communicating with the second cavity;
• wherein the partition defines a plurality of slots extending therethrough along the vertical direction;
• the partition comprises a bottom surface exposed to the first cavity and a top surface exposed to the second cavity;
• the first end portion of each heat exchange tube is inserted into a corresponding slot, without protruding beyond the top surface of the partition, through the wall of the manifold and the first cavity in sequence, so that the micro-channel of each heat exchange tube is in communication with the second cavity via the corresponding slot.
