Abstract

Disclosed is a heat exchanger, including: at least two heat exchange tube groups—wherein each heat exchange tube group includes at least two heat exchange tubes; and a connecting member, wherein the at least two heat exchange tubes are communicated with each other by the connecting member—the at least two heat exchange tube groups are connected by the connecting member, and the at least two heat exchange tube groups are not communicated with each other.

First claim

What is claimed is:

1. A heat exchanger, comprising:
at least two heat exchange tube groups, wherein each heat exchange tube group comprises at least two heat exchange tubes; and
a connecting member, wherein the at least two heat exchange tubes in the each heat exchange tube group are communicated with each other by the connecting member, the at least two heat exchange tube groups are connected by the connecting member, and the two heat exchange tube groups are not communicated with each other;
wherein the connecting member comprises a plate member and a plurality of communication portions, each of the plurality of communication portions has a convex hull, the plurality of communication portions correspond to a plurality of convex hulls, the plate member and the plurality of convex hulls form communication cavities, the communication cavities are separated from each other, and each communication cavity is communicated with the at least two heat exchange tubes in the each heat exchange tube group;
wherein in a same heat exchange tube group of the at least two heat exchange tube groups, the same heat exchange tube group comprises one heat exchange tube at an inlet side and one heat exchange tube at an outlet side, a distance from an end of the heat exchange tube located at the inlet side away from the connecting member to the connecting member being different from a distance from an end of the heat exchange tube located at the outlet side away from the connecting member to the connecting member; the heat exchanger tube on the inlet side and the heat exchange tube on the outlet side are arranged parallel in a width direction of the heat exchanger tube; a flow area of the heat exchange tube located at the inlet side is different from a flow area of the heat exchange tube located at the outlet side.

2. The heat exchanger as claimed in claim 1 , wherein the connecting member has a heat exchange tube groove into which the heat exchange tube is inserted.

3. The heat exchanger as claimed in claim 1 , wherein the plate member is bent, and a predetermined included angle is formed between the two heat exchange tube groups.

4. The heat exchanger as claimed in claim 1 , wherein the plate member comprises: a first plate member, a second plate member, and a connecting portion arranged between the first plate member and the second plate member.

5. The heat exchanger as claimed in claim 4 , wherein the connecting portion is integrally arranged with the first plate member and the second plate member, and the connecting portion is protruded towards a side without the heat exchange tube.

6. The heat exchanger as claimed in claim 4 , wherein the connecting portion comprises a first extension arm extending from a side of the first plate member close to the second plate member and bent, and a second extension arm arranged on the second plate member, wherein the second extension arm is connected with and opposites to a surface of the first extension arm.

7. The heat exchanger as claimed in claim 4 , wherein the first plate member and the second plate member are spaced apart from one another, the plate member further comprises a third plate member, and the first plate member and the second plate member are connected by the third plate member.

8. The heat exchanger as claimed in claim 1 , wherein the heat exchange tube and the communication portions are located at a same side of the plate member; or the heat exchange tube and the plate member are located at a same side of the communication portions.
