Problems solved by technology

Among them, there is an 8-10cm (arc part) condenser at the bending part B. Since the heat exchange fins cannot be arranged in strict parallel, the wind resistance of this part of the condenser is extremely high, resulting in basically ineffective heat transfer in this part

Embodiment 1

[0036] Embodiment 1: An outdoor unit of an air conditioner

[0037] See attached Figure 3-5 As shown, it includes a condenser 1, a blower fan 2, a compressor 5 and a casing 3. The casing 3 has an air duct inside, and the air duct has an air inlet 40 and an air outlet 41. The first condensing unit 10 An air inlet 40 located in the air duct.

[0038] The condenser 1 is composed of a first condensing unit 10, a second condensing unit 11 and a connecting pipe 100; the first condensing unit 10 is located at the air inlet 40 of the air duct, and the second condensing unit 11 is located at the The air outlet 41 of the air duct; the fan 2 is arranged in the air duct and is located between the first condensing unit 10 and the second condensing unit 11 . At this time, the rotating surface of the fan 2 is parallel to the first condensing unit 10 and the second condensing unit 11, and the first condensing unit 10 and the second condensing unit 11 are opposite to the fan 2. Of course, t...

Embodiment 2

[0056] Embodiment 2: The rest is the same as Embodiment 1, except that the distance between the second cooling fins 15 in the second condensing unit is 6mm.

Embodiment 3

[0057] Embodiment 3: The rest is the same as Embodiment 1, except that the distance between the second cooling fins 15 in the second condensing unit 11 is 10 mm.

[0058] The following is the energy efficiency ratio comparison experiment of the air conditioner outdoor unit of the present invention and the air conditioner outdoor unit of the existing L-type condenser according to the national standard, and the experimental data of the energy efficiency ratio obtained by selecting different spacings for the second cooling fins is tabulated as follows:

[0059]

[0060] It can be seen that, with the gradual increase of the distance between the second cooling fins, the lost air volume is gradually reduced, and the energy efficiency of the air conditioner is also gradually increased compared with the energy efficiency of the existing air conditioner with an L-shaped condenser.

Abstract

The invention relates to an air conditioner outdoor unit which comprises a condenser, a draught fan, a compressor and a shell. An air duct is formed in the shell. The condenser comprises a first condensation unit and a second condensation unit which are arranged oppositely in parallel. The first condensation unit comprises a first copper tube and first cooling fins. The second condensation unit comprises a second copper tube and second cooling fins. The input port of the first copper tube is communicated with the output port of the second copper tube. The distance between every two adjacent first cooling fins is smaller than the distance between every two adjacent second cooling fins. By means of the air conditioner outdoor unit, the technical prejudice that the cooling area of the condenser needs to be enlarged to improve the cooling effect of the condenser and the condenser and an evaporator of an air conditioner need to be enlarged to increase the energy efficiency ratio of the air conditioner is eliminated. The energy efficiency ratio of the air conditioner can be increased while the cooling area of the condenser is narrowed, and unexpected effects are achieved.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to an outdoor unit in a split air conditioner. Background technique [0002] The general layout of the condenser and the fan inside the existing air conditioner external unit is as attached Figure 1-2 As shown, in the shell of the air conditioner external unit, the condenser adopts the straight part A to connect the bent part B with rounded corners. The purpose of the bent part B is to extend the length of the condenser without increasing the width of the external unit, thereby increasing the The heat transfer area in the condenser. Among them, there is an 8-10cm (arc part) condenser at the bending part B. Since the heat exchange fins cannot be arranged in strict parallel, the wind resistance of this part of the condenser is extremely high, resulting in basically ineffective heat transfer in this part. [0003] The air-conditioning industry believes that in order to imp...
