Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
An outdoor unit 100 of an air conditioner according to an embodiment of the present invention is described below with reference to fig. 1 to 8.
As shown in fig. 1 to 3, an outdoor unit 100 of an air conditioner according to an embodiment of the present invention includes: the heat exchanger comprises a shell 1, a heat exchanger 2, a compressor 3, a fan 4, a middle partition plate 6 and an electric control box 7. The housing 1 defines a receiving chamber therein, and the heat exchanger 2, the compressor 3 and the blower 4 are respectively disposed in the receiving chamber, and the compressor 3 and the blower 4 are disposed at a front side of the heat exchanger 2 at a spaced apart relationship.
The middle partition plate 6 is provided in the accommodation chamber to partition the accommodation chamber into the compressor placement chamber 11 and the fan placement chamber 12, the middle partition plate 6 includes a front sub-plate 61 and a rear sub-plate 62, the front end of the front sub-plate 61 is connected to the front wall surface of the housing 1, and the front sub-plate 61 is located between the compressor 3 and the fan 4, and the rear sub-plate 62 extends rearward from the rear end of the front sub-plate 61 toward a direction away from the fan 4.
The automatically controlled box 7 is established on the back minute board 62 and is located the compressor and places the chamber 11, and automatically controlled box 7 includes: the box body 71, the circuit board 72 and the radiator 73 are arranged in the box body 71, the circuit board 72 is vertically arranged, the radiator 73 comprises a radiating substrate 732 and a plurality of radiating fins 731 arranged on the radiating substrate 732, the radiating substrate 732 is connected with the circuit board 72, the plurality of radiating fins 731 penetrate through the box body 71 and the middle partition plate 6 and then extend into the fan placing cavity 12, an air passing groove 733 is defined between every two adjacent radiating fins 731, and at least part of the air passing groove 733 extends along the horizontal direction.
In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc., are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
It will be appreciated that the electric control box 7 is placed in the compressor placement cavity 11 of the compressor placement cavity 11 on one side of the middle partition plate 6, and in such a mounting position, the electric control box 7 cannot obstruct the air flow in the fan placement cavity 12, so that the performance of the air duct can be prevented from being influenced. After the circuit board 72 is vertically arranged, the whole electric control box 7 can be vertically arranged, at the moment, the electric control box 7 is correspondingly clung to the middle partition plate 6, the electric control box 7 occupies small area horizontally, and the internal layout of the air conditioner indoor unit 100 is very compact.
In the embodiment of the invention, the radiator 73 partially extends into the fan placing cavity 12 to radiate heat in the fan placing cavity 12 (that is, a part of the radiator 73 is located between the middle partition plate 6 and the heat exchanger 2), at least a part of the air passing groove 733 of the radiator 73 extends along the horizontal direction, and the air flow in the fan placing cavity 12 is basically horizontally moved from back to front under the driving of the fan 4, so that the extending direction of the air passing groove 733 is substantially consistent with the air flowing direction driven by the rotation of the fan 4, and the radiating effect of the radiator 73 is excellent. Therefore, the fins 731 of the heat sink 73 can be made smaller than conventional ones, and the cost can be reduced by about half.
Alternatively, as shown in fig. 5, the plurality of fins 731 of the radiator 73 are vertically spaced apart, and all the fins 731 on the radiator 73 extend in a horizontal direction, so that all the air passing grooves 733 of the radiator 73 extend in a horizontal direction, and thus the extending direction of all the air passing grooves 733 is consistent with the airflow direction driven by the fan 4, and the heat dissipation effect of the radiator 73 can be further improved.
It can be understood that if the direction of the air flow in the fan placement cavity and the direction of the air passing groove of the cooling fin form 90 degrees, the air flow cannot smoothly flow into the air passing groove, and the heat dissipation effect of the radiator is poor. In addition, on the side facing the fan placing chamber 12, in the vertical direction of the middle partition plate 6, the wind speed is maximum at the middle position surface of the middle partition plate 6, and the wind speed is minimum at the two ends of the middle partition plate 6. If the radiator is positioned at the uppermost part of the middle partition plate, the wind speed is minimum, and the radiating effect is also poor.
In the embodiment of the present invention, the plurality of fins 731 of the radiator 73 are vertically spaced apart, so that most of the fins 731 of the radiator 73 are close to the middle part of the middle partition 6 where the wind speed is high, and the extending direction of all the air passing grooves 733 is consistent with the flowing direction of the air flow driven by the fan 4. Here, since the circuit board 72 is vertically disposed, a larger contact area may be provided between the heat sink 73 and the circuit board 72, so that heat generated by the electrical components on the circuit board 72 can be dissipated as much as possible through the heat sink 73.
According to the air conditioner outdoor unit 100 of the embodiment of the invention, the radiator 73 of the electric control box 7 passes through the box body 71 and the middle partition plate 6 and then extends into the fan placing cavity 11, and at least part of the air passing grooves 733 extend along the horizontal direction, so that the extending direction of the air passing grooves 733 of the radiator 73 is consistent with the airflow flowing direction driven by the fan, and the heat exchange area between the circuit board 72 and the radiator 73 is large due to the vertical arrangement of the circuit board 72, so that the heat dissipation effect on the electric control box 7 is improved, the radiator 73 can be made smaller, and the production cost of the radiator 73 is reduced.
In some embodiments, as shown in FIG. 3, a plurality of fins 731 are located at the junction of front sub-plate 61 and rear sub-plate 62. The wind speed at the connection of the front and rear sub-plates 61 and 62 is large in view of the wind speed distribution in the fan housing chamber 12, so that the heat dissipation is facilitated by the heat dissipation fins 731.
Of course, in practical application, the extending position of the radiator 73 may be reset according to the result of the actual wind speed analysis and the specific structural layout, which is not limited herein.
Specifically, as shown in fig. 4 and 7-8, the front sub-plate 61 and the rear sub-plate 62 are in arc transition, the middle partition plate 6 is provided with a notch 63 which is opened upwards at the arc transition, and a plurality of cooling fins 731 are fitted at the notch 63.
