Abstract
An evaporator of a refrigerator provided in a cool air passage includes a serpentine heat-exchanging pipe and a heat-exchanging member wound around the pipe. The heat-exchanging member is shaped in a band having two longitudinal edges. One longitudinal edge of the heat-exchanging member is contacted with the circumference of the pipe, and the other longitudinal free edge thereof has a plurality of cut-off portions. Respective axis of each straight portion of pipe are parallel to each other and in the direction of the air flow.
Claims3
In an evaporator of a refrigerator provided in a cool air passage for heat-exchanging the cool air circulated in a refrigerating compartment and a freezing compartment, said evaporator comprising
- a serpentine heat-exchanging pipe containing refrigerant, respective axis of each straight portion of said pipe being substantially parallel to each other and generally in the direction of air flow through said cool air passage;
- and
- a heat-exchanging member provided around a circumference of said heat-exchanging pipe in a spiral manner, wherein said heat-exchanging member is shaped as a band having two longitudinal end portions, one longitudinal end portion of said band-shaped heat-exchanging member is in contact along the circumference of said heat-exchanging pipe and the other longitudinal end portion of said band-shaped heat-exchanging member which is free from being in contact with said heat-exchanging pipe is sloped upstream in the direction of the cool air flow.
In an evaporator of a refrigerator provided in a cool air passage for heat-exchanging the cool air circulated in a refrigerating compartment and a freezing compartment, said evaporator comprising
- a serpentine heat-exchanging pipe containing refrigerant, the respective axis of each straight portion of said pipe being substantially parallel to each other and generally in the direction of air flow through said cold air passage;
- and
- a heat-exchanging member provided around a circumference of said heat-exchanging pipe in a spiral manner, wherein said heat-exchanging member is shaped as a band having two longitudinal end portions, one longitudinal end portion of said band-shaped heat-exchanging member is in contact along the circumference of said heat-exchanging pipe
- wherein the other longitudinal end portion of said heat-exchanging member which is free from being in contact with said heat-exchanging pipe is perpendicular to the direction of cool air flow.
