Heat exchanger and fin of the same

Abstract

A heat exchanger and a fin of the same are provided. The heat exchanger includes a tube, a plurality of fins, a slit section, and a condensed water guide. The tube is arranged in at least a front row and a rear row with respect to a direction of airflow. The plurality of fins is installed with the tube passing therethrough. The slit section is formed on the fins and includes a plurality of slits. The condensed water guide is formed between at least the front row and the rear row, for guiding a draining of condensed water that is generated on a surface of the tube. A fin of the heat exchanger includes a plurality of tube insert holes, a slit section, and a condensed water guide. A refrigerant tube is inserted in the plurality of tube insert holes. The slit section includes a plurality of slits formed around the tube insert holes. The condensed water guide is formed at a rear side of one of the slits, and guides a draining of condensed water generated in a heat exchange process between refrigerant and air.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a fin of a heat exchanger, and more particularly, to a heat exchanger and a fin of the same for promptly draining condensed water to increase a heat exchanging efficiency of the heat exchanger and prevent a carry-over phenomenon where condensed water overflows into an indoor area. [0003] 2. Description of the Related Art [0004] In general, a heat exchanger is an apparatus for exchanging heat between refrigerant and air, and has various applications including air conditioners. Heat exchangers are mainly embodied in the form of finned tubes. [0005] In a heat exchanger according to a related art, a plurality of fins is vertically stacked and spaced from each other by a predetermined distance. A tube is installed through the fins and bent multiple times, through which refrigerant circulates. The fin is installed perpendicular to the tube to expand an area of heat exchange between the ref...

AI Technical Summary

Benefits of technology

[0021] An advantage of the present invention is the promp draining away of condensed water generated on a surface of a fin to prevent the condensed water from flowing into an indoor area.

[0022] Another advantage of the present invention is that heat exchanging efficiency is improved through prompt drainage of the condensed water to reduce power consumption of the heat exchanger.

Problems solved by technology

However, a plurality of slits in the structure of the heat exchanger fin according to a related art prevents condensed water from flowing, so that the condensed water cannot drain quickly away.

Such condensed water becomes a heat insulating layer between the surface of the heat exchanger and the outer air, decreasing the efficiency of the heat exchanger for heat transfer.
