Abstract
A heat exchanger includes: a manifold having a manifold opening passing through a pipe wall of the manifold; a distribution pipe disposed in the manifold and having a distribution pipe opening passing through a pipe wall of the distribution pipe; and a connecting pipe assembly including a first connecting pipe The first connecting pipe is inserted in the manifold opening, has an end connected to the distribution pipe at the distribution pipe opening, and is in fluid communication with the distribution pipe. Thereby, the space occupied by the connecting pipe assembly in the manifold can be reduced.

A heat exchanger, comprising:
- a manifold having a manifold opening passing through a pipe wall of the manifold;
- a distribution pipe disposed in the manifold and having a distribution pipe opening passing through a pipe wall of the distribution pipe;
- a connecting pipe assembly comprising a first connecting pipe, wherein the first connecting pipe is inserted in the manifold opening, has an end connected to the distribution pipe at the distribution pipe opening, and is in fluid communication with the distribution pipe;
- wherein the first connecting pipe comprises a flange extended towards a radial outside from the end of the first connecting pipe, wherein the flange is connected to a portion of the pipe wall of the distribution pipe surrounding the distribution pipe opening,
- wherein an inner diameter of the end of the first connecting pipe is smaller than an inner diameter of the distribution pipe opening;
- and
- the connecting pipe assembly further comprises an insertion pipe, wherein a first end of the insertion pipe close to the first connecting pipe is inserted in the distribution pipe opening, and an end face of the first end of the insertion pipe abuts against an end face of the end of the first connecting pipe, and a second end of the insertion pipe opposite to the first end is located in the distribution pipe.
