ABSTRACT:
A cooling unit has a cooling casing for forming an air passage, and a cooling heat exchanger disposed in the cooling casing. The cooling casing is composed of upper and lower cases detachably connected to each other in an up-down direction on a connection portion therebetween. The lower case has a first end surface on the connection portion at an inside of the cooling casing, and a protrusion portion protruding toward the upper case from the first end surface. On the other hand, the upper case has a second end surface contacting the first end surface on the connection portion, and a recess portion into which the protrusion portion is fitted. Further, a step portion downwardly stepped from the first end surface is formed in the lower case on an inside of the protrusion portion at a position proximate to the opening portion. Thus, a space is formed under the second end surface of the upper case. As a result, condensed water entered into a clearance between the first end surface of the lower case and the second end surface of the upper case falls downwardly through the space.
