Abstract

Provided are a connection tube and a condenser. The connection tube includes: multi-row tubes respectively connecting a flow path between a pair of header pipe assemblies disposed to be spaced apart from each other and including a plurality of header pipes disposed to be parallel to each other in a second direction, perpendicular to a first direction which is a length direction of the header pipe having the flow path formed therein and a plurality of connection holes formed in one surface.

First claim

What is claimed is:

1 . A connection tube comprising multi-row tubes respectively connecting a flow path between a pair of header pipe assemblies disposed to be spaced apart from each other and including a plurality of header pipes disposed to be parallel to each other in a second direction, perpendicular to a first direction which is a length direction of the header pipe having the flow path formed therein and a plurality of connection holes formed in one surface,
wherein the multi-row tube includes a plurality of single tubes respectively extending in the second direction, disposed to be spaced apart from each other in the second direction, and having two ends each inserted into the flow path through the connection hole of the header pipe assembly, and a wing connected between the plurality of single tubes, and chamfers are formed on two edges of each of the two ends of the single tubes.

2 . The tube of claim 1 , wherein the single tube has a plurality of microchannels formed therein, and
the chamfer is formed across the microchannel adjacent thereto at each of the two edges of each end of the single tubes.

3 . The tube of claim 1 , wherein when viewed in the first direction, each end of the single tubes has a length allowing the end to be inserted up to at least a central portion of the flow path.

4 . The tube of claim 3 , wherein when viewed in the first direction, each end of the single tubes has a length allowing the end to be inserted beyond at least the central portion of the flow path, and is spaced apart from an inner wall of the flow path facing the connection hole.

5 . The tube of claim 4 , wherein the header pipe has a circular cross section, and
when viewed in the first direction, each end of the single tubes has a length allowing the end to be inserted in a range of 0.5 to 0.75 of a diameter of the flow path.

6 . The tube of claim 1 , wherein when the single tubes are inserted into the flow path, an insertion length of the end of the single tubes with respect to the flow path is limited by contact between an end of the wing and an outer surface of the header pipe.

7 . The tube of claim 1 , wherein the plurality of wings are provided, and the plurality of the wings have the same length in a third direction.

8 . A condenser comprising:
a first header pipe assembly and a second header pipe assembly disposed to be spaced apart from each other and each including a plurality of header pipes disposed to be parallel to each other in a second direction, perpendicular to a first direction which is a length direction of the header pipe having a flow path formed therein and a plurality of connection holes formed in one surface; and the connection tube according to claim 1 , which connects the flow path of the first header pipe assembly and that of the second header pipe assembly to each other, and extends in a third direction, perpendicular to the first direction and the second direction.

9 . The condenser of claim 8 , further comprising:
a connection block extending in the first direction, disposed between and in contact with the respective header pipes, and having a plurality of flow holes passing through two surfaces of the connection block that are in contact with the header pipes; and a fixing baffle disposed on two sides of the header pipe assembly in the first direction, and including a plurality of blocking parts blocking the flow path of the header pipe and spaced apart from each other in the second direction, and a fixing part connecting the plurality of blocking parts to each other.
