<P>PROBLEM TO BE SOLVED: To provide an air cooler avoiding supply failure of compressed air due to freezing. Ž<P>SOLUTION: First distribution parts 80, 81, 82 and second distribution parts 83, 84 are formed on an inlet side bracket 21 having an air inlet 20. Third distribution parts 90, 91, 92 and fourth distribution parts 93, 94 are formed on an outlet side bracket 31 having an air outlet 30. Pipes 40, 41, 42 with fins and pipes 50, 51 without fins are arranged in parallel between the inlet side bracket 21 and the outlet side bracket 31. A high cooling flow passage 70 is configured by the pipes 40, 41, 42 with fins. A low cooling flow passage 71 is configured by pipes 50, 51 without fins. The flow passage cross sectional area of the low cooling flow passage 71 is smaller than that of the high cooling flow passage 70. The air outlet 30 is at a position higher than the pipes 40, 41, 42 with fins. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
