Problems solved by technology

However, in order to obtain sufficient heat transfer performance, the surface area of ​​the corrugated fins must be increased
In addition, in the case of using louver fins, sufficient heat transfer performance can be achieved even if the surface area of ​​the fins is small, but when the air conditioner operates in winter, frost is likely to be formed on the fins, thereby greatly reducing the heat transfer performance

Embodiment Construction

[0020] Advantages, features and aspects of various embodiments (of the invention) will become apparent from the ensuing description when taken in conjunction with the drawings set forth below. Terms and words used in the following description are not limited to common or dictionary definitions, but can be interpreted with appropriate meanings and definitions consistent with technical ideas.

[0021] A heat exchanger is a device installed on or in, for example, an air conditioner for heat exchange, and a finned tube heat exchanger is mainly used in such an air conditioner system.

[0022] Fin and tube heat exchangers can include fins and tubes. As fins provided on or in pipes through which refrigerant flows, louver fins and corrugated fins are widely used. The louver fin has a structure in which a part of the fin is cut and bent, and the corrugated fin has a structure in which a metal plate is bent several times to form a "W" shape.

[0023] The corrugated fins are characteri...

Abstract

A fin (100) for a heat exchanger is provided that may include a fin body (110) having a first heat exchange area (111), and a second heat exchange area (112), which is disposed to be adjacent to the first heat exchange area; a fin collar (120) that passes through the fin body (110) and protrudes from the fin body (110), and a plurality of fin portions (130,140) formed at or on the fin body (110) and having different shapes from each other.

Description

technical field [0001] The invention discloses a heat exchanger fin and a heat exchanger with the fin. Background technique [0002] Fins for heat exchangers and heat exchangers having such fins are known. However, they suffer from various drawbacks. [0003] A heat exchanger is a device installed on or in, for example, an air conditioner for heat exchange, and a finned tube heat exchanger is mainly used in such an air conditioner system. [0004] Fin and tube heat exchangers can include fins and tubes. As fins provided on or in pipes through which refrigerant flows, louver fins and corrugated fins are widely used. The louver fin has a structure in which a part of the fin is cut and bent, and the corrugated fin has a structure in which a metal plate is bent several times to form a "W" shape. [0005] The corrugated fins are characterized in that very little frost forms on them. However, in order to obtain sufficient heat transfer performance, the surface area of ​​the c...
