PURPOSE:To contrive the thinning of a cooling unit without inviting any deterioration of the flow rate of air. CONSTITUTION:An axial flow fan or a cooling fan 5 is provided horizontally in parallel to the wall surface 2 of a ceiling in an unit case 3, fixed to the wall surface 2 of the ceiling in a refrigerating chamber, a cooler 4 is provided so as to be neighbored to the outer periphery of the diametral direction of the cooling fan 5. A fan shroud 9, covering the outer periphery of the cooling fan 5, and a bulkhead 10, covering the outer periphery of the fan shroud 9 semicircularly, are provided in the unit case 3 while a pressure chamber 11, formed of the bulkhead 10, and the fan shroud 9 are provided with optimum configurations whereby air, sucked by the cooling fan 5, can be ventilated to the side of the cooler 4. |
