Claims

[Scope of utility model registration request]

At least one first flow path A through which a heat exchange first fluid flows, and second and third flow paths B through which a heat exchange second fluid and a heat exchange third fluid to be heat exchanged with the first fluid flow, respectively. It is equipped with a flow path C,
At least one second flow path B is arranged on one side of one first flow path A, or the second flow paths B and the first flow paths A are arranged alternately or irregularly. and at least one on the same side.
three third passages C are arranged, or the third passages C and the first passages A are arranged alternately or irregularly, and all the passages A, B, and C are made of an aluminum brazing sheet. The first flow path A is separated by a spacer 2 interposed between the upper and lower edges of the flat plate 2.
A second flow path B is formed by the bars 3, 3 and a fin member 4 disposed between the spacer bars 3, 3, and is interposed between the front and rear edges of the flat plate 2. It consists of both side walls 6, 6, and a plate-like connecting wall 7 extending between the side walls 6, 6, and is cut up from the connecting wall 7 and protrudes upward and downward. The third flow path C is formed by a second flow path forming body 5 having a projection 8 and a fluid passage hole 9 facing all the arched projections 8, By the third flow path forming body 10 consisting of both side walls 11, 11 interposed between the edges and a plate-like connecting wall 12 that spans the both side walls 11, 11 and has parallel fins 13 on both the left and right sides. Heat exchanger being formed.
