Abstract (en)
[origin: EP3279599A1] Provided are a heat exchanger (100) and a multi-split system having the same. The heat exchanger (100) comprises a branch pipe (1) and a collecting pipe (2). The branch pipe (1) comprises a body (11), an inlet (12), and multiple flow separation holes. The inlet (12) is formed in the bottom of the body (11). The multiple flow separation holes are distributed in the side wall of the body (11) in the length direction of the body (11). In the direction from the bottom to the top, the body (11) comprises multiple segments of pipe bodies. In every two adjacent segments of pipe bodies, the flow area of a downstream pipe body is smaller than the flow area of an upstream pipe body, the height of each segment of pipe body is not greater than 0.5 meters, and the number N of the pipe bodies is greater than or equal to 2 and less than or equal to 3. The collecting pipe (2) and the branch pipe (1) are communicated by means of multiple heat exchange pipes, the multiple heat exchange pipes are distributed at intervals in the vertical direction, and the collecting pipe (2) has a refrigerant outlet (21).
