Since the first air passing opening 131 is closer to the heat conducting portion 21 than the second air passing opening 132, the air flow flowing from the first air passing opening 131 to the heat dissipating portion 22 can flow to the end of the heat dissipating portion 22 close to the heat conducting portion 21 as much as possible, the air flow flowing from the second air passing opening 132 to the heat dissipating portion 22 can flow to the end of the heat dissipating portion 22 away from the heat conducting portion 21 as much as possible, and the air flow flowing from the first air passing opening 131 to the heat dissipating portion 22 and the air flow flowing from the second air passing opening 132 to the heat dissipating portion 22 can also flow to the portion between the two ends of the heat dissipating portion 22. The comprehensive airflow can act on the part of the heat dissipation part 22 close to the heat conduction part 21 and the part far away from the heat conduction part 21 through the first air passing opening 131 and the second air passing opening 132, so that the airflow flowing through the heat dissipation part 22 is increased, and the heat exchange area between the airflow and the heat dissipation part 22 is increased. Moreover, the end of the heat dissipating part 22 close to the heat conducting part 21 is the highest temperature position on the heat dissipating part 22, and the air flowing from the first air passing opening 131 to the heat dissipating part 22 directly flows to the end of the heat dissipating part 22 close to the heat conducting part 21, so that the highest temperature position on the heat dissipating part 22 can be better dissipated, that is, the technical scheme of the utility model can greatly improve the heat dissipating effect of the electronic control box 100.
In one embodiment, the box body 10 is provided with a partition 14 for partitioning between the heat dissipation chamber 12 and the mounting chamber 11, and the first air passing opening 131 is provided in the partition 14 to communicate the mounting chamber 11 and the heat dissipation chamber 12. That is, the heat dissipation cavity 12 and the installation cavity 11 are separated by the partition plate 14, and the partition plate 14 is arranged through passing a first opening, so that the airflow firstly flows into the installation cavity 11, and then flows to the heat dissipation part 22 from the first air passing opening 131, so that the airflow can take away part of heat in the installation cavity 11 through the airflow in the process of flowing through the installation cavity 11, and the heat dissipation effect in the installation cavity 11 is favorably improved. Of course, the present invention is not limited thereto, and in other embodiments, the first air passing opening 131 may also be disposed on a wall of the heat dissipation chamber 12 adjacent to the partition 14 to directly communicate with the compressor chamber 31 or directly communicate with a space outside the outer casing 30.
In an embodiment, the installation cavity 11 is provided with an air inlet 135, the air inlet 135 is used for communicating with the compressor cavity 31 of the outdoor unit of the air conditioner, one side of the partition plate 14 facing the installation cavity 11 is provided with a flow guiding surrounding wall 15, the flow guiding surrounding wall 15 and the partition plate 14 surround to form a flow guiding channel 16, one end of the flow guiding channel 16 is communicated with the first air passing opening 131, and the other end of the flow guiding channel extends towards the air inlet 135. In this embodiment, the heat dissipating portion 22 and the heat conducting portion 21 are distributed in the vertical direction, the first air passing opening 131 and the second air passing opening 132 are distributed in the vertical direction, the mounting cavity 11 has a first cavity bottom wall 111, the first cavity bottom wall 111 is connected to the lower end of the partition plate 14, and the air inlet 135 is disposed on the first cavity bottom wall 111. One end of the flow guiding surrounding wall 15 surrounds the edge of the first air passing opening 131, the other end extends towards the air inlet 135, one end of the flow guiding surrounding wall 15, which is far away from the first air passing opening 131, is spaced from the air inlet 135, and the flow guiding surrounding wall 15 and the part of the partition plate 14, which is located at the lower side of the first air passing opening 131, surround to form a flow guiding channel 16. That is, the air guiding channel 16 is inclined in the vertical direction, so that one end of the air guiding channel 16 faces the heat dissipating portion 22 and the other end of the air guiding channel 16 faces the air inlet 135. Make air intake 135, diversion channel 16 and the one end that radiating part 22 is close to heat-conducting part 21 roughly lie in a straight line, thereby after the air current flowed into installation cavity 11 from air intake 135, can flow through diversion channel 16 straight one end that heat-conducting part 21 is close to towards radiating part 22, so that the one end that the air current that flows to radiator 20 from first air inlet 131 can be comparatively concentrated flow direction radiating part 22 and be close to heat-conducting part 21, the effect position is more direct more accurate, can dispel the heat to the highest position of temperature on the radiating part 22 better. And can avoid the air current to flow to the condition that changes from the in-process of air intake 135 flow direction heat dissipation portion 22 better for the air current flows to the in-process of heat dissipation portion 22 from air intake 135, and air current running resistance is little, the loss is few, guarantees that the air current flows to the velocity of flow and the flow that heat dissipation portion 22 is close to the one end of heat conduction portion 21 all great, can further promote the radiating effect that heat dissipation portion 22 is close to the one end of heat conduction portion 21.
In addition, since the compressor chamber 31 does not have an outdoor heat exchanger (condenser), the temperature of the compressor chamber 31 is relatively low compared to the heat exchange chamber 32 provided with the outdoor heat exchanger, and the heat dissipation effect is better when the heat is dissipated to the heat sink 20 by the airflow flowing through the compressor chamber 31. Compared with the condition that the air inlet 135 is directly communicated with the space outside the outer machine shell 30, the possibility that external water vapor enters the electric control box 100 can be reduced, and the electric safety of the electric control box 100 is ensured. Of course, the present invention is not limited thereto, and in other embodiments, the heat dissipation portion 22 and the heat conduction portion 21, the first air passing opening 131 and the second air passing opening 132 may also all extend in the transverse direction. In addition, in other embodiments, the air inlet 135 may also be directly communicated with the space outside the outer machine casing 30, for example, the air inlet 135 may be directly communicated with the space outside the outer machine casing 30 through a ventilation duct; or when the part of the box body 10 provided with the air inlet 135 is attached to the outer machine shell 30, the outer machine shell 30 is provided with a through hole; or a portion of the box body 10 provided with the air inlet 135 is protruded to the outside of the outer casing 30.

That is, the size of the end of the guide passage 16 near the air inlet 135 is larger than that of the first air passing opening 131, and the size of the guide passage 16 gradually increases in the direction near the air inlet 135, that is, the guide passage 16 has a bell-mouth structure. In the process that the airflow flows from the air inlet 135 to the first air passing opening 131, the flow rate of the airflow is gradually increased, so that the flow rate of the airflow flowing to the heat dissipation portion 22 is relatively high, and the heat dissipation effect of the heat dissipation portion 22 is further improved.

At least the top peripheral wall 121 of the top peripheral wall 151 and the partition 14 extends obliquely in a direction away from the heat sink 20 in a direction from the heat dissipating portion 22 toward the heat conductive portion 21. With this arrangement, while the cross-sectional area of the diversion channel 16 is ensured to be gradually increased in the direction approaching the air inlet 135, the end of the diversion channel 16 away from the first air passing opening 131 can be ensured to extend toward the air inlet 135, so that the air inlet 135, the diversion channel 16 and the end of the heat dissipation portion 22 approaching the heat conduction portion 21 are approximately aligned.

The present invention further provides an outdoor unit of an air conditioner, which includes an outdoor unit casing 30 and an electronic control box 100, and the specific structure of the electronic control box 100 refers to the above embodiments, and since the outdoor unit of the air conditioner employs all technical solutions of all the above embodiments, the outdoor unit of the air conditioner at least has all the beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein. The electronic control box 100 is mounted on the external casing 30, the external casing 30 is provided with a heat exchange cavity 32, and the heat dissipation cavity 12 of the electronic control box 100 is communicated with the heat exchange cavity 32 through the mounting opening 133. In this embodiment, the outdoor unit of the air conditioner further includes an outdoor fan, an outdoor heat exchanger, and a compressor assembly, the outdoor unit casing 30 has a heat exchange cavity 32 and a compressor cavity 31, the outdoor fan and the outdoor heat exchanger are disposed in the heat exchange cavity 32, the compressor assembly is disposed in the compressor cavity 31, and the electronic control box 100 is disposed above or beside the compressor assembly. The electrical control box 100 may be installed in the compressor cavity 31, or may be integrally disposed above the compressor cavity 31.
In one embodiment, an outdoor fan is disposed in the heat exchange cavity 32, and the mounting port 133 is communicated with a negative pressure side of the outdoor fan. That is, when the outdoor fan works, the outdoor fan may generate negative pressure at the mounting opening 133, so as to drive the airflow of the compressor cavity 31 to flow to the outdoor fan after flowing through the heat sink 20 from the first air passing opening 131 and the second air passing opening 132, and thus, by using the manner that the outdoor fan drives the airflow to flow through the heat sink 20, additional fans may be avoided, the structure of the outdoor unit of the air conditioner may be simplified, the energy consumption of the outdoor unit of the air conditioner may be reduced, and the cost may be reduced.
When the air conditioner outdoor unit of the technical scheme of the present invention adopts the above-mentioned electronic control box, the negative pressure generated by the outdoor fan can be used to drive the airflow of the compressor cavity 31 to flow through the heat sink 20 from the first air passing opening 131 and the second air passing opening 132, so as to dissipate the heat of the heat sink 20. Because the first air passing opening 131 is closer to the heat conducting portion 21 than the second air passing opening 132 in the electronic control box, the air flowing from the first air passing opening 131 to the heat dissipating portion 22 can flow to the end of the heat dissipating portion 22 close to the heat conducting portion 21 as much as possible, the air flowing from the second air passing opening 132 to the heat dissipating portion 22 can flow to the end of the heat dissipating portion 22 away from the heat conducting portion 21 as much as possible, and the air flowing from the first air passing opening 131 to the heat dissipating portion 22 and the air flowing from the second air passing opening 132 to the heat dissipating portion 22 can also flow to the portion between the two ends of the heat dissipating portion 22. The comprehensive airflow can act on the part of the heat dissipation part 22 close to the heat conduction part 21 and the part far away from the heat conduction part 21 through the first air passing opening 131 and the second air passing opening 132, so that the airflow flowing through the heat dissipation part 22 is increased, and the heat exchange area between the airflow and the heat dissipation part 22 is increased. And the one end that the heat dissipation part 22 is close to heat conduction part 21 is the highest position of temperature on the heat dissipation part 22, through making the air current that flows to the heat dissipation part 22 from first air inlet 131 directly flow to the one end that the heat dissipation part 22 is close to heat conduction part 21, so can dispel the heat to the highest position of temperature on the heat dissipation part 22 better, greatly reduced the overheated risk of automatically controlled box 100.
