INTAKE AIR COOLING DEVICE

PROBLEM TO BE SOLVED: To provide an intake air cooling device capable of reducing in size while suppressing a large amount of condensed water being sucked into a combustion chamber at one time.SOLUTION: A second cooling part 34 is located above a first cooling part 33, and located above an air intake port 11a as well. Condensed water 37 generated at the second cooling part 34 reaches a combustion chamber 11b with the suction air steadily, so that damage on an internal combustion engine 11 caused by the condensed water 37 generated at the second cooling part 34 can be suppressed. Also, the condensed water 37 generated at the first cooling part 33 reaches the combustion chamber 11b after passing through the second cooling part 34 located above. Therefore, the condensed water generated at the first cooling part 33, with gravity becoming a resistance, flows into the second cooling part 34 gradually. Also, as the second cooling part 34 itself becomes a resistance against the flow of the condensed water 37 from the first cooling part 33, it can be suppressed that a large amount of condensed water from the first cooling part 33 flows into the combustion chamber 11b at one time.
