It can be understood that the air flow flowing from the first air inlet 34 to the electronic control box assembly 3 passes through the top of the PCB assembly 32 and the heat sink 33, so as to dissipate heat from the top of the heat sink 33 and the PCB assembly 32, the PCB assembly 32 is a heat generating source, the top of the heat sink 33 directly contacts with the PCB assembly 32, and the top of the heat sink 33 is the position where the temperature of the heat sink 33 is highest, so that the first air inlet 34 and the top of the heat sink 33 and the PCB assembly 32 are oppositely arranged, the heat at the highest temperature place can be taken away, and the heat dissipation efficiency of the PCB assembly 32 and the heat sink 33 is improved.

Alternatively, as shown in fig. 1 and 2, the flow guide 313 includes a first flow guide 3131, a second flow guide 3132 and a third flow guide 3133, which are sequentially arranged from top to bottom, an upper end of the first flow guide 3131 is spaced apart from an inner top wall of the electrical control box 31 to define a first air flow inlet 34, a lower end of the first flow guide 3131 is spaced apart from an upper end of the second flow guide 3132 to define a second air flow inlet 35, and a lower end of the second flow guide 3132 is spaced apart from an upper end of the third flow guide 3133 to define a third air flow inlet 36. The structure of the flow guide 313 can be simplified to facilitate the arrangement of the first air inlet 34, the second air inlet 35 and the third air inlet 36.

In addition, the baffle 313 may further include a first side plate and a second side plate, the first side plate and the second side plate are respectively disposed at both sides of the heat sink 33 in the first direction, the first side plate is connected to one ends of the first, second, and third baffle plates 3131, 3132, and 3133 in the first direction, the second side plate is connected to the other ends of the first, second, and third baffle plates 3131, 3132, and 3133 in the first direction, the first and second side plates are connected to the electronic control box 31, and the first, second, and third baffle plates 3131, 3132, and 3133 are connected to the electronic control box 31 through the first and second side plates, respectively.

Further, as described in fig. 1 and 2, the lower end of the first deflector 3131 and the second deflector 3132 are inclined downward in the direction of the fan cavity 11 to the compressor cavity 12. Specifically, in the example shown in fig. 2, the lower end of the first guide plate 3131 is inclined downward in the direction from the fan chamber 11 to the compressor chamber 12 (left-to-right direction as shown in fig. 2), and the second guide plate 3132 is inclined downward in the direction from the fan chamber 11 to the compressor chamber 12 (left-to-right direction as shown in fig. 2). Therefore, the lower end of first guide plate 3131 and the upper end of second guide plate 3132 can guide the airflow flowing to second airflow inlet 35 in compressor cavity 12, thereby facilitating the airflow flowing and reducing the noise in the airflow flowing process. The lower end of second deflector 3132 may guide the airflow flowing into third airflow inlet 36 in compressor cavity 12, so as to facilitate the airflow flowing and reduce the noise generated during the airflow flowing process.

Further, as shown in fig. 2, the second deflector 3132 comprises a first section and a second section which are connected in series, both of which are inclined downward in the direction from the fan chamber 11 to the compressor chamber 12. And the angle of inclination of the first section is greater than the angle of inclination of the second section. Wherein the angle of inclination is the angle between the first and second sections and the direction of the blower chamber 11 to the compressor chamber 12.

In some embodiments of the present invention, as illustrated in fig. 2, third deflector 3133 is inclined upward in the direction of fan chamber 11 to compressor chamber 12. It is understood that the distance between the third deflector 3133 and the heat sink 33 is gradually increased in the direction from bottom to top, so that the third deflector 3133 can be spaced apart from the heat sink 33, and the air flow can be made to flow through the area of the heat sink 33 opposite to the third deflector 3133, thereby ensuring the heat dissipation effect of the heat sink 33.

Alternatively, second deflector 3132 is spaced apart from radiator 33 in the direction from fan chamber 11 to compressor chamber 12, and at least part of first deflector 3131 is spaced apart from radiator 33 in the direction from fan chamber 11 to compressor chamber 12, so that the airflow can flow through the various parts of radiator 33, achieving a better heat dissipation effect for radiator 33.

As shown in fig. 1, the upper end of the first flow guiding plate 3131 is bent and extended toward the heat sink to form a stop portion 3131a, the stop portion 3131a stops against the heat sink 33, and the stop portion 3131a can fix and support the heat sink 33. In addition, one end of the stop portion 3131a close to the heat sink 33 extends upward, so that a contact area with the heat sink 33 is increased, and a fixing and supporting effect on the heat sink 33 is improved.

In some embodiments of the present invention, as shown in fig. 3, the lower end of first deflector 3131 is located on the side of second deflector 3132 away from fan cavity 11, and the lower end of first deflector 3131 is lower than the upper end of second deflector 3132. On the one hand, the second air flow inlet 35 can be directed downwards towards the compressor chamber 12, so that the air flow in the compressor chamber 12 can enter more rapidly through the second air flow inlet 35, while the lower end of the first deflector 3131 and the second deflector 3132 are inclined downwards in the direction from the fan chamber 11 to the compressor chamber 12, so that the air flow can be better guided into the second air flow inlet 35; on the other hand, as shown in fig. 3, in the process that water drops flow towards the compressor cavity 12, because the lower end of the first guide plate 3131 is located below the upper end of the second guide plate 3132, it is possible to make the first guide plate 3131 and the second guide plate 3132 be arranged in a staggered manner in the up-and-down direction, the first guide plate 3131 and the second guide plate 3132 block the water drops, the water drops cannot directly enter the compressor cavity 12, and therefore the water drops are not easy to be sprayed onto the soundproof cotton or the compressor, the compressor is prevented from rusting, and the electrified wire body and the terminal in the compressor cavity 12 are not easy to be splashed, so that a short circuit is caused, and the safety is improved.

It can be understood that, among the correlation technique, air condensing units generally sets up in outdoor, rainy day, the rainwater gets into in the casing easily to get rid of to the compressor intracavity through the air current import very easily under the effect of fan, set up compressor and soundproof cotton in the compressor intracavity, the water that gets into the compressor intracavity makes the compressor rust easily, and has more connecting wire and side connection terminal in the compressor cavity, spatters electrified line body and terminal department very easily, causes the short circuit, has great potential safety hazard. Alternatively, the overlapping height of the first and second guide plates 3131 and 3132 in the up-down direction is greater than 2mm, for example, the overlapping height of the first and second guide plates 3131 and 3132 in the up-down direction may be 2mm, 2.5mm, 3mm, 3.5mm, or 4mm, etc., without limitation, thereby better preventing rainwater from being thrown into the compressor cavity 12, resulting in rusting of the compressor, etc.

Further, as shown in fig. 1 and 3, a lower end of second deflector 3132 is located on a side of third deflector 3133 away from fan cavity 11, and a lower end of second deflector 3132 is lower than an upper end of third deflector 3133.
