PURPOSE:To reduce the size of a heat exchanger by a structure wherein through holes are provided on plate members and laminated wire sheets are packed in each through hole and in addition refrigerant passages equipped with fins are arranged in the inner periphery outside the plate member. CONSTITUTION:Through holes 2 are provided on plate members 4. Further, laminated wire sheets 21 are packed in each through hole 2. In addition, refrigerant passages 5 equipped with fins 22 are arranged in the inner periphery outside the plate members 4l. Due to the structure as mentioned above, because the heating surface area per unit volume and the heat transfer coefficient increases, the size, especially the length of a heat exchanger can be reduced. |
