Benefits of technology

The patent describes a type of heat exchanger that can efficiently distribute refrigerant to its tubes, even when used as an outdoor unit. This prevents the heat exchanger from performing poorly and ensures good heat exchange.

Problems solved by technology

In the case that a parallel flow type heat exchanger with vertical headers is used as an evaporator of an outdoor unit, distribution of a refrigerant from the vertical headers to the tubes becomes unbalanced due to gravity and variation of physical properties of the refrigerant according to a physical phase of the refrigerant.

Embodiment Construction

[0044]Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

[0045]FIG. 1 is a view illustrating an external appearance of a heat exchanger according to an exemplary embodiment of the present invention, FIG. 2 is an exploded view illustrating constituents of a second header of the heat exchanger shown in FIG. 1, and FIG. 3 is an exploded view illustrating constituents of a first header of the heat exchanger shown in FIG. 1.

[0046]Referring to FIGS. 1 to 3, the heat exchanger 10 is a parallel flow type heat exchanger having a vertical header. The heat exchanger 10 includes a plurality of tubes 60 having a refrigerant flowing therethrough and may be horizontally disposed to exchange heat with external air, a pair of headers 20 and 30 vertically disposed to guide the refrigerant to the tubes 60 and communicate with the tubes 60, and...

Abstract

A heat exchanger including a plurality of tubes disposed horizontally, a pair of vertical headers connecting the tubes, and at least one flow distribution baffle mounted to a header at one group of the plurality of tubes such that the flow distribution baffle is positioned between tubes of the one group. Each of the at least one flow distribution baffle is provided with at least one distribution hole allowing a refrigerant to pass therethrough. The heat exchanger prevents unbalanced distribution of the refrigerant when it operates as an evaporator of an outdoor unit.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application No. 10-2013-0083460, filed on Jul. 16, 2013 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Field of the Invention[0003]Embodiments of the present invention relate to a heat exchanger provided with a vertical header having an improved performance of distribution of a refrigerant.[0004]2. Description of the Related Art[0005]A heat exchanger, which is an apparatus causing a refrigerant to exchange heat with external air, generally includes tubes having a refrigerant flowing therethrough and arranged to exchange heat with external air, a heat exchange fin contacting the tubes to increase the heat dissipation area, and a header allowing ends of the tubes to communicate with each other in order to guide the refrigerant to the tubes and adapted to support the tubes.[0006]Heat exchangers include a fin tube t...
