Abstract

A heat exchanger may be manufactured using an apparatus which includes a rotating body configured to be disposed at one side of heat exchange fins having an insertion groove having one side formed to be depressed and placed to be downwardly directed to be rotatable. An inner side of the insertion groove of transferred heat exchange fins are seated on the rotating body. The apparatus also include a rotating blade configured to be connected to the rotating body to be rotatable together with the rotating body. The rotating blade supports the other side of the heat exchange fins to prevent the heat exchange fins from being deviated from the rotating body.

First claim

What is claimed is:

1. An apparatus for manufacturing a heat exchanger, the apparatus comprising:
a rotating body configured to be disposed at one side of heat exchange fins having an insertion groove in a downwardly directed position, the rotating body being further configured to be rotatable and to seat an inner side of the insertion groove of the heat exchange fins on the rotating body; and
a rotating blade configured to be connected to the rotating body to be rotatable together with the rotating body, and configured to support an other side of the heat exchange fins to prevent the heat exchange fins from being deviated from the rotating body.

2. The apparatus as claimed in claim 1 , wherein the rotating body includes a seating surface disposed to be parallel to a transfer direction of the heat exchange fins and is configured to have the heat exchange fins placed thereon.

3. The apparatus as claimed in claim 2 , wherein the rotating blade includes:
a vertical blade part protruding from an upper portion of the seating surface and disposed at a front portion of the seating surface in relation to the transfer direction of the heat exchange fins; and
a horizontal blade part connected to the vertical blade part, and protruding toward a rear portion of the seating surface.

4. The apparatus as claimed in claim 3 , wherein the horizontal blade part includes a supporting surface supporting the other side of the heat exchange fins and disposed to be parallel to the seating surface.

5. The apparatus as claimed in claim 2 , wherein the rotating blade is changeable to:
a first position at which the heat exchange fins are placed on the seating surface; and
a second position at which the insertion groove is disposed to be in an upwardly directed position by rotating the rotating blade together with the rotating body.

6. The apparatus as claimed in claim 1 , wherein the rotating blade includes:
a first rotating blade connected to one side of an outer surface of the rotating body; and
a second rotating blade connected to the outer surface of the rotating body and disposed at an opposite side of the first rotating blade.

7. The apparatus as claimed in claim 1 , further comprising a rotating shaft configured to be inserted into a through-hole formed at a center of the rotating body,
wherein the rotating shaft is rotated by 180° at a preset time.

8. The apparatus as claimed in claim 1 , further comprising a rotating shaft configured to be inserted into a through-hole formed at a center of the rotating body,
wherein a plurality of rotating bodies are disposed at a preset interval along a length direction of the rotating shaft.

9. The apparatus as claimed in claim 1 , further comprising a pressing block configured to be disposed at one side of the rotating body and to press a refrigerant tube into the insertion groove in a state in which the heat exchange fins are reversed so that the insertion groove is in an upwardly directed position by a rotation of the rotating body.

10. The apparatus as claimed in claim 9 , wherein the pressing block is disposed over the heat exchange fins to be elevated toward the heat exchange fins, and
a lower end of the refrigerant tube is sequentially pressed into the insertion groove.

11. The apparatus as claimed in claim 9 , wherein the pressing block includes:
a first block part of which a lower end is spaced apart from an upper end of the heat exchange fins; and
a second block part connected to one side of the first block part, and having a lower end protruding to be lower than the first block part.

12. The apparatus as claimed in claim 11 , wherein the pressing block is movable along a length direction of the heat exchange fins, and
the refrigerant tube is pressed in a first pressing state in which the refrigerant tube is pressed into the insertion groove by a lowering of the first block part, and a second pressing state in which the refrigerant tube is pressed into the insertion groove by a lowering of the second block part.

13. The apparatus as claimed in claim 11 , wherein a distance between a lower end of the first block part and a lower end of the second block part is 20% to 50% of a height of the refrigerant tube.
