wherein the plurality of distributing pipes comprises a plurality of straight pipes and a plurality of multi-way pipes.

2. The refrigerant distributing device according to claim 1 , wherein the plurality of distributing pipes is configured as capillary pipes.

3. The refrigerant distributing device according to claim 1 , wherein the plurality of straight pipes and the plurality of multi-way pipes are connected detachably.

4. The refrigerant distributing device according to claim 1 , wherein the plurality of multi-way pipes comprises at least one of three-way pipes, four-way pipes and six-way pipes.

5. The refrigerant distributing device according to claim 1 , wherein the distributing structure is configured as a network structure.

6. The refrigerant distributing device according to claim 5 , wherein the distributing structure is configured as a two-dimensional network structure.

7. The refrigerant distributing device according to claim 6 , wherein the two-dimensional network structure comprises a plurality of rectangular units.

8. The refrigerant distributing device according to claim 5 , wherein the distributing structure is configured as a three-dimensional network structure.

9. The refrigerant distributing device according to claim 8 , wherein the three-dimensional network structure comprises two mutually orthogonal rectangular two-dimensional network structures.

10. The refrigerant distributing device according to claim 1 , wherein the adapting block is further provided with a connecting hole communicated with the adapting chamber and configured to fit with the plurality of distributing pipes.

11. The refrigerant distributing device according to claim 1 , further comprising a stopper provided with a blind hole which is configured to fit with the plurality of distributing pipes.

12. A heat exchanger, comprising:
a first header and a second header;
a plurality of heat exchanging pipes, each heat exchanging pipe defining a first end connected to the first header and a second end connected to the second header;
a fin disposed between two adjacent heat exchanging pipes; and
a refrigerant distributing device, disposed within at least one of the first header and the second header, wherein the refrigerant distributing device includes:
a distributing structure comprising a plurality of distributing pipes, at least one of the plurality of distributing pipes being provided with a distributing hole, at least two of the plurality of distributing pipes intersecting with each other; and
an adapting block provided with an adapting chamber, and connected to the distributing structure such that the adapting chamber is communicated with an inner chamber of the distributing pipe;
wherein the plurality of distributing pipes comprises a plurality of straight pipes and a plurality of multi-way pipes.

13. The heat exchanger according to claim 12 , wherein the plurality of straight pipes and the plurality of multi-way pipes are connected detachably.

14. The heat exchanger according to claim 12 , wherein the plurality of multi-way pipes comprises at least one of three-way pipes, four-way pipes and six-way pipes.

15. The heat exchanger according to claim 12 , wherein the distributing structure is configured as a network structure.

16. The heat exchanger according to claim 15 , wherein the distributing structure is configured as a two-dimensional network structure.

17. The heat exchanger according to claim 15 , wherein the distributing structure is configured as a three-dimensional network structure.

18. The heat exchanger according to claim 12 , wherein the adapting block is further provided with a connecting hole communicated with the adapting chamber and configured to fit with the plurality of distributing pipes.
