COOLING UNIT FOR VEHICULAR AIR CONDITIONER

PROBLEM TO BE SOLVED: To restrain condensed water generated in an evaporator, from being scattered to the lower reaches side and to simplify constitution for restraining the scatter of the condensed water. SOLUTION: Air velocity is high on the outside of a sharp turn of air flow on the lower reaches of air (lower side) of an evaporator 13, and air velocity is low on the inside of the turn. A phenomenon of condensed water 105 being blown up on a case internal wall surface 18a to be the outside of the turn by the air flow of high air velocity is generated in a second draft air duct 18, which causes scattering of condensed water. A rib 19 protruded into the second draft air duct 18 is therefore disposed at a turn outside part 18a where air velocity becomes high in the second draft air duct 18, and the rib 19 restrains the condensed water from being blown up along the turn outside part 18a.
