Problems solved by technology

When the size of the outer fuselage is increased, it will cause the following three problems: it will lead to a decrease in the aesthetics of the product, and it will cause inconvenience in installation; due to the increase in the heat exchanger, more flow paths are required, the process is more complicated, and it is easy to cause shunting The heat transfer performance of the whole heat exchanger is not high; it is necessary to increase the size of the wind wheel or increase the speed to meet the requirements of the new heat exchanger, which leads to problems such as increased noise

no. 1 example

[0021] see figure 2 , the outdoor unit of the air conditioner includes a compressor 1, a heat exchanger and a wind wheel arranged in the frame of the outdoor unit. The wind wheel and heat exchanger in the frame of the split outdoor unit adopt a left-right structure; the wind wheel includes the left wind wheel 2 and the right wind wheel 4 arranged in the horizontal direction, and the heat exchanger includes the left heat exchanger 3 and the right heat exchanger arranged in the horizontal direction. The heat exchanger 5, the left and right heat exchangers are respectively arranged on the sides of the left and right wind wheels; the air inlet 6 shared by the left wind wheel 2 and the right wind wheel 4 is arranged on the surface of the outdoor machine frame, and the surface of the outdoor machine frame corresponds to The left wind wheel 2 and the right wind wheel 4 are provided with a left air outlet 7 and a right air outlet 8 in opposite directions. The compressor 1 is located...

no. 2 example

[0025] see image 3 The air inlet 6 shared by the left wind wheel 2 and the right wind wheel 4 is located in the middle of the frame surface of the outdoor unit, the left heat exchanger 3 is located on the right side of the left wind wheel 2, and the right heat exchanger 5 is located on the left side of the right wind wheel 4. In this example, the wind wheel is an axial flow wind wheel, which adopts the air suction method for heat exchange. See the first embodiment for the rest of the undescribed parts, and will not repeat them here.

no. 3 example

[0027] see Figure 4 , the frame surface of the outdoor unit is provided with independent left air inlet 9 and left air outlet 7 corresponding to the left wind wheel 2, and is provided with independent right air inlet 10 and right air outlet 8 corresponding to the right wind wheel 4. The frame of the outdoor unit is provided with partitions 11 that divide it into left and right sides; the left side of the frame of the outdoor unit is provided with a left wind wheel 2 and a left heat exchanger 3, and the surface of the left part is provided with a left air inlet 9 and The left air outlet 7; the right wind wheel 4 and the right heat exchanger 5 are arranged in the right part of the outdoor unit frame, and the right air inlet 10 and the right air outlet 8 are arranged on the surface of the right part. In this example, the left wind wheel is an axial flow wind wheel, and the heat exchange is carried out by means of exhaust air, and the right wind wheel is a centrifugal wind wheel....

Abstract

The invention discloses an air-conditioner outdoor unit, which comprises a compressor, heat exchangers and wind wheels arranged in an outdoor unit framework, wherein the wind wheels and the heat exchangers in the split outdoor unit framework have left and right structures; the wind wheels comprises left wind wheel and a right wind wheel arranged in the horizontal direction, the heat exchangers comprise a left heat exchanger and a right heat exchanger arranged heat exchangers, the left heat exchanger and the right left heat exchanger are arranged on the sides of the left wind wheel and the right wind wheel respectively; the surface of the outdoor unit framework is provided with an air inlet shared by the left wind wheel and the right wind wheel, and the surface of the outdoor unit framework is provided with a left air outlet and a right air outlet corresponding to the left wind wheel and the right wind wheel respectively; or, the surface of the outdoor unit framework is provided with a left air inlet and a left air outlet corresponding to the left wind wheel and provided with a right air inlet and a right air outlet corresponding to the right wind wheel. By adopting the structure of double wind wheels and double heat exchangers arranged on left and right, the air-conditioner outdoor unit not only can effectively increase the air quantity and the heat exchange efficiency of the heat exchangers, but also can effectively avoid the problem of inconvenient installation due to over high body.

Description

technical field [0001] The invention relates to an air conditioner outdoor unit. Background technique [0002] Traditional split air conditioner outdoor unit, if attached figure 1 As shown, it adopts a heat exchanger 101 with one or two upper and lower axial flow wind wheels 102 structure. With the implementation of new energy efficiency standards in my country and other countries, the size of traditional air conditioner outdoor units no longer meets the current energy efficiency requirements. In order to meet the requirements of energy efficiency standards, it is necessary to increase the size of the outdoor unit of the air conditioner (increase the heat exchange area of ​​the heat exchanger, the size of the wind wheel and the motor). When the size of the outer fuselage is increased, it will cause the following three problems: it will lead to a decrease in the aesthetics of the product, and it will cause inconvenience in installation; due to the increase in the heat excha...
