PROBLEM TO BE SOLVED: To provide a lamination type heat exchanger exhibiting high heat exchanging performance.SOLUTION: A lamination type heat exchanger 40 includes core parts 41 constituted by laminating core plates 41a, 41b. Offset type fins 41f are arranged in a plurality of refrigerant passages 41rf formed at the core parts 41. The offset type fins 41f promote flow of liquid component of refrigerant and contribute to improve a heat exchange efficiency. Outer edge cylindrical portions 41a2 of the core plates 41a are laminated in multi-layers at outer peripheral surfaces of the core parts 41. End portions of the core parts 41 are provided with end plates 41d. The end plates 41d are thicker than the core plates 41a, 41b. A connecting member 43 acting as an inlet for the refrigerant is connected at an additional connecting part 43b, to a main connecting part 43a around a through-pass passage 41ri for the refrigerant. |
