Benefits of technology

[0015]The method may further comprise the step of disposing ridges away from the opposite longitudinal edges of the plate, thereby allowing the welding of the opposite longitudinal edges of the plate without deformation.

Problems solved by technology

However, the refrigerant flowing in a central portion of the tube does not transfer heat as actively.
Thus, a portion of the refrigerant flowing within the tube transfers heat relatively poorly with the surrounding air, resulting in reduced heat transfer efficiency.

Embodiment Construction

[0032]Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.

[0033]Referring to FIG. 1, a refrigeration cycle of a refrigerator is illustrated. The refrigeration cycle is a closed circuit and comprises a compressor 3, a condenser 4, a capillary tube 5, a drier 7, an evaporator 6, and interconnecting refrigerant tubes 8. The capillary tube 5 may be replaced with other expansion devices, such as an expansion valve.

[0034]The compressor 3 serves to compress a refrigerant into a high-temperature and high-pressure gas-phase refrigerant. The condenser 4 serves to condense the refrigerant from the compressor 3 into a high-temperature and high-pressure liquid-phase refrigerant. The drier 7 may be installed on an intermediate position o...

Abstract

A heat exchanger for a refrigerator and a method for manufacturing a tube thereof with improved heat exchanger heat transfer efficiency. The heat exchanger for a refrigerator comprising of: a tube to guide a refrigerant; and a plurality of ridges disposed on an inner peripheral surface of the tube, the ridges configured to cause the refrigerant flowing along the tube to form a turbulent flow. The method of manufacturing a tube having a plurality of ridges comprising the steps of: providing a surface of a plate; forming ridges on the surface of the plate; and coupling opposite longitudinal edges of the plate such that the surface of the plate provided with the ridges becomes an inner peripheral surface of the tube.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. §119(a) to Korean Patent Application No. 2006-0039725, filed on May 2, 2006 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.[0002]The application is related to Korean Patent Application No. 2006-0039724, filed on May 2, 2006, in the Korean Intellectual Property Office and currently pending as U.S. patent application Ser. No. ______.FIELD OF THE INVENTION[0003]The present invention relates to a heat exchanger for a refrigerator. In particular, the present invention relates to a heat exchanger for a refrigerator in which a refrigerant flowing along a tube has a turbulent flow, resulting in improved heat transfer efficiency.BACKGROUND OF THE INVENTION[0004]Generally, a refrigerator is an apparatus to cool a storage chamber with cold air produced by an evaporator of a refrigeration cycle, so as to keep contents stored in th...
