It further comprises a reverse burring portion (151-1a) formed in a shape extending to.

The reverse burring portion 115-1a is formed to protrude outward from the outer circumference of the fixed baffle hole 115-2 in the longitudinal direction of the header tank 100, so as to surround the insertion portion 310 of the manifold 300. .

This increases the joint area between the insertion part 310 of the manifold 300 and the fixed baffle 115, thereby increasing the joint force between the manifold 300 and the first header tank 100, thereby increasing the rigidity of the heat exchanger 1000. In addition to manufacturing, it is possible to prevent the heat exchange medium from leaking to the outside.

The reverse burring unit 115-1a may be manufactured by bending the outer side of the header tank 100 from the fixed baffle body 115-1 in the longitudinal direction, but the reverse burring unit 115-1a is not limited thereto. May be formed in the fixed baffle 115.

In this case, the reverse burring portion 115-1a is formed to extend outward in the longitudinal direction of the header tank 100, but may increase the bonding force with the insertion part 310, but extends outward in the longitudinal direction of the header tank 100. Due to this, insertion of the insertion unit 310 may be difficult.

To this end, the reverse burring unit 115-1a may be formed in a shape in which the inner diameter increases gradually as the inner diameter of the end portion proceeds in the end direction such that the inner diameter of the end portion is larger than the outer diameter of the inserting portion 310. That is, the reverse burring portion 115-1a is formed in a shape in which the inner diameter is gradually increased as it proceeds toward the end direction, so that the insertion portion 310 can be easily inserted through the guide according to the insertion of the insertion portion 310, and the manifold ( 300 may be inserted into the first header tank 110 to the correct depth.

As another embodiment, the reverse burring portion 115-1a may be formed in a shape that is bent in the direction of separation of the header tank 100 such that the inner diameter of the end portion is larger than the outer diameter of the insertion portion 310.

That is, the reverse burring unit 115-1a has an end portion formed in a shape that is bent in a spaced apart direction of the header tank 100, that is, in a spaced direction of the first header tank 110 and the second header tank 120. The inner diameter may be larger than the outer diameter of the 310 to facilitate the insertion of the insertion part 310.

In addition, the fixed baffle hole 115-2 of the heat exchanger 1000 including the fixed baffle 115 including the reverse burring unit 115-1a has an inner diameter in the longitudinal direction of the header tank 100.
