CN2449179Y - All copper/copper-aluminium alloy heat-exchanging fin for air conditioner - Google Patents

Abstract

The utility model discloses a whole copper/copper-aluminium alloy heat-exchanging fin for an air conditioner. Punching gaps and perforations of a heat exchange copper pipe are distributed on the utility model. The utility model and a U-shaped heat exchange copper pipe form a heat exchanger. A group of fins are bundled together by the U-shaped heat exchange copper pipe through the perforations. The fins are divided into three sections, wherein, a lower section is long. A middle section and an upper section are short. The three section are all bent into circular arc shapes along an annular axial-flow fan. The whole heat exchange fins form one C shape. The utility model has the advantages of high thermal efficiency, low noise, good strength, difficult deformation, difficult oxidation and enhancement of the service life of the air conditioner.

Description

A kind of air-conditioner copper/albronze heat exchange fin entirely

The utility model relates to a kind of room air conditioner heat exchange fin, specifically, relates to the heat exchange fin of a kind of room air conditioning evaporator and condenser.

At present, the heat exchanger indoor unit of room air conditioner mainly contains one-part form and two-part, and every section all is rectilinear form, and wherein the two-part heat exchanger is formed by stacking by two sections linearity fins bending certain angles, or directly is formed by stacking by the fin of two sections once-formings.The fin of this structure, its two end portions is far away from annular axial-flow fan, and it is nearer from fan to be parallel to the part at tangential direction place in annular axial-flow fan cross section, therefore, air-flow skewness when causing heat exchange makes the heat exchange inequality, the heat exchange effect is relatively poor, and noise is bigger.Simultaneously, the heat exchange fin that adopts is generally aluminium flake at present, and heat exchanger effectiveness is lower than copper fin, and the too late copper fin of intensity, and easily oxidation is yielding, directly influences the service life of air-conditioner.

It is even that the purpose of this utility model provides a kind of heat exchange, and the heat exchange efficiency height can reduce noise again effectively, is difficult for oxidation, and the good air-conditioner heat exchange fin of intensity.

For reaching above-mentioned purpose, the utility model adopts a kind of complete copper or albronze heat exchange fin, be distributed with the perforation of calking and heat exchange copper pipe on it, this fin and U type heat exchange copper pipe are formed heat exchanger, and U type heat exchange copper pipe is through one group of fin together by its perforation, and this fin is divided into three sections, hypomere is longer, stage casing and epimere are shorter, and upper, middle and lower all bend to circular arc along annular axial-flow fan for three sections, and whole heat exchange fin constitutes a C shape.

The heat exchange fin of the utility model and prior art relatively, has following tangible advantage: 1. because the each several part of heat exchange fin of the present utility model is all closer apart from annular axial-flow fan, during heat exchange, air-flow is comparatively even, and heat exchange is also comparatively abundant, thereby, improved heat exchange efficiency, and the air flow that enters heat exchanger is all vertical substantially with the fin calking, and the resistance that is subjected to is less, and the noise of generation is also less.2. owing to the utility model adopts complete copper or albronze, heat exchanger effectiveness is improved than aluminous fin, and better than aluminous fin intensity, and is not yielding, is difficult for oxidation, thereby, the service life that can improve air-conditioner.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is prior art two-part fin user mode figure;

Fig. 2 is a structural representation of the present utility model.

Heat exchange fin among Fig. 1 is divided into hypomere 1 and epimere 2, and to annular axial-flow fan 4 bendings, hypomere 1 and epimere 2 are linear pattern to epimere 2, are distributed with calking 8 and copper pipe perforation 9 on it at bending mouthful 3 places, and hypomere 1 and epimere 2 are the aluminium flake drawing.As seen from Figure 1, the upper part of the end portion of hypomere 1 and epimere 2 is all far away from annular axial-flow fan 4, and when heat exchange, air quantity is less, the air-flow inequality, and heat exchanger effectiveness is low, and aluminium matter heat transfer efficiency is also not as good as copper in addition.

As shown in Figure 2, the heat exchange fin of present embodiment adopts copper entirely, be divided into 7 three sections of hypomere 5, stage casing 6 and epimeres, be distributed with calking 8 and copper pipe perforation 9 on every section, hypomere 5 is longer, and stage casing 6 and epimere 7 are shorter, and stage casing 6 and epimere 7 all bend to annular axial-flow fan 4 at bending mouthful 3 places, and 5,6,7 three sections all bend to circular arc along annular axial-flow fan 4, make whole heat exchange fin constitute a C shape.The fin of structure like this, its various piece is all closer apart from fan 4, and during heat exchange, air-flow is just comparatively even, and heat exchange is also comparatively abundant, and it is vertical with fin calking 8 to enter the heat exchanger air flow, and the resistance that is subjected to is less, and the noise of generation is also less.Copper in addition heat transfer efficiency is higher than aluminium matter, thereby uses the utility model can obtain very high heat exchange efficiency.

Claims (1)

1. an air-conditioner is with copper/albronze heat exchange fin entirely, be distributed with calking (8) and heat exchange copper pipe perforation (9) on it, this fin and U type heat exchange copper pipe are formed heat exchanger, U type heat exchange copper pipe is through one group of fin together by perforation (9), it is characterized in that this fin is divided into three sections, hypomere (5) is longer, and stage casing (6) and epimere (7) are shorter, upper, middle and lower all bend to circular arc along annular axial-flow fan (4) for three sections, and whole heat exchange fin constitutes a C shape.
