PURPOSE:To send rearward the whole cooling air taken in from the front for improving the cooling efficiency by disposing the front end of a heat transfer cooling member behind the front edge of an opening of a radiator and behind the front end of a water passage member. CONSTITUTION:A radiator 12 is provided with water passage members 121 spaced vertically from each other and laminated, and a heat transfer cooling member 130 corrugated left and right is interposed between these members 121. In this case, the front edge (a) of the member 130 is disposed behind the front edge (b) of the member 121 which is disposed behind the front end of an opening (c) of the radiator 12. Thus, air flowing from the opening (c) into the radiator 12 is at first guided from the front end (b) of the member 121 to the upper and lower surfaces thereof, flows rearward, abuts against the front edge (a) of the member 130 to be divided left and right and then further flows rearward. Thus, the whole air is sent rearward to improve the cooling efficiency. |
