Cooling apparatus for a machine room of a refrigerator using a nacelle-shaped duct

摘要

A cooling system for a machine room of a refrigerator is provided. More particularly, a cooling system for a machine room of a refrigerator is provided, which is capable of cooling the machine room of the refrigerator using a smaller blowing fan in a nacelle-shaped or nacelle duct, which can acquire more air than using conventional fan blades, remarkably reducing noise of the fan and ensuring sufficient space, thereby efficiently cooling the compressor and the condenser installed in the machine room. The apparatus for cooling a machine room of a refrigerator may include a compressor installed in the machine room, a condenser installed in the machine room and connected to the compressor via a connection pipe, and a nacelle duct installed in the machine room that cools the compressor and the condenser by blowing air, the nacelle duct having a central opening.

主权项

1. An apparatus for cooling a machine room of a refrigerator, the apparatus comprising:
a compressor installed in the machine room; a condenser installed in the machine room and connected to the compressor via a connection pipe; a nacelle duct installed in the machine room that cools the compressor and the condenser by blowing air, the nacelle duct having a central opening; and a machine room case forming an outer wall of the machine room and including at least one inlet located at a bottom surface of the machine room case to face a lower portion of the nacelle duct, wherein the nacelle duct comprises:
a blowing device having the central opening, the blowing device having an air flow path that functions as an internal path for air flow and a blow nozzle that discharges air;a fan mounting device connected to the blowing device at a lower portion of the nacelle duct and fixed on the bottom surface of the machine room case to correspond to the inlet of the machine room case; anda blowing fan installed in the fan mounting device to suck in external air and blow the sucked in external air toward the blowing device, wherein the fan mounting device comprises an external air inlet located to face the inlet of the machine room case to form a direct introduction path for the external air, the external air being used to cool the machine room.
