US 6,098,705 A · Coil type condenser for refrigerator

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.

A condenser for refrigerator, said condenser comprising:

a pipe wound spirally to face a blowing direction of cool air generated by a cooling fan of the refrigerator, the pipe including 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;
and
a support member welded to the pipe for supporting the pipe, wherein the support member includes
a first support welded to at least one of the upper and lower horizontal portions and left and right vertical portions of the odd and even numbered coils for supporting the odd and even numbered coils on a first same plane,
a second support welded to at least one of the upper and lower horizontal portions and left and right vertical portions of the odd numbered coils for supporting the odd numbered coils on a second same plane, and
a third support welded to at least one of the upper and lower horizontal portions and left and right vertical portions of the even numbered coils for supporting the even numbered coils on a third same plane.
