PURPOSE:To improve cooling by introducing cool air into a cool box from a cooling unit and providing a compact exclusive evaporator in the cool box. CONSTITUTION:Cool air is introduced in a cool box 12 through a connecting pipe 1g introducing port 14b in a fan casing 1f of a cooling unit 1. The cool air, after passing through the cool box 12, is discharged from exhaust ports 14c, 12c to the outside. Also, since an exclusive evaporator 13 is disposed in the cool box 12, cooling action of this evaporator 13 is added to that of said introduced cool air. Thus, the interior of the cool box 12 is sufficiently cooled to cool properly materials 15 to be cooled, which can be removed by opening a lid 12a of the cool box 12 in a car room. |
