Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2005/066560
Kind Code:
A1
Abstract:
A refrigerator has a box body having a cooling room and a machine room, a refrigeration cycle provided in the box body and having a compressor, a condenser, a pressure reducer, and an evaporator to form a refrigerant flow path, a refrigerant sealed in the refrigeration cycle and flowing in the refrigerant flow path, and a blower for forcibly cooling the condenser. The condenser is received in the machine room. The condenser has a pipe and fins provided on the pipe. The pipe is formed in a spiral shape with gaps so as to form a substantially tubular inner space having a first opening and an opening on the opposite side of the first opening. The blower is opposite the first opening, and airflow resistance between the second opening and the inner space is higher than airflow resistance between the gaps and the inner space. The machine room of the refrigerator is small, and the refrigerator has high heat radiation capability and consumes less electric power. Further, refrigerant leakage caused by bending, breakage, etc. of a pipe of the condenser can be prevented.
