Cooling Device And Construction Machine

A cooling device comprising:

• a main pipe comprising an introduction pipe configured to introduce a charge air supercharged by a supercharger, a first aftercooler connected to the introduction pipe, and a discharge pipe configured to discharge the charge air from the first aftercooler;
• a branch pipe comprising a branch pipe branched from the introduction pipe, a second aftercooler connected to the branch pipe, and a joint pipe connecting the second aftercooler to the discharge pipe;
• and
• a cooling fan configured to supply a cooling wind to the first aftercooler and the second aftercooler, wherein
• the first aftercooler and the second aftercooler are disposed to be shifted from each other in a rotation axis direction of the cooling fan and in a direction perpendicular to the rotation axis direction and are disposed not to be overlapped with each other in the rotation axis direction of the cooling fan.
