ABSTRACT:
A coil type condenser for a refrigerator holds a flow of air which cools the condenser by securing a condenser length enough to radiate heat and simultaneously holding enough pitch. In the coil type condenser, a pipe is wound spirally to face a blowing direction of cool air generated by a cooling fan of the refrigerator. The pipe includes a plurality of coils formed integrally each having upper and lower horizontal portions and left and right vertical sides, each of even numbered coils of the coils having a size different from that of each of odd numbered coils thereof. A support member welded to the pipe supporting the pipe. According to the condenser, since pitches between coils forming the coil type condenser are short, a suitable coil length of the condenser can be maintained in a narrow space. Thus, the coil type condenser can prevent an excessive pressure from generating when a compressor initially operates and can used for a small or medium refrigerator.
