[0033] The following is combined Figures 1 to 3 The embodiments of this utility model are described below.

[0034] One heat dissipation structure in this embodiment includes:

[0035] Partition 1, wherein heat dissipation vent 11 is provided on partition 1;

[0036] An electrical control box 2 is disposed on the middle partition 1; an air outlet 21 is provided on one side of the electrical control box 2, and an air inlet 23 and an installation port 22 are provided on the side of the electrical control box 2 opposite to the air outlet 21, and the air outlet 21 covers the heat dissipation port 11.

[0037] Heat dissipation component 4 is disposed on the electrical control box 2; the air outlet side of the heat dissipation component 4 faces the air inlet 23;

[0038] A flow guiding component 5 is disposed inside the electrical control box 2, and the flow guiding component 5 is used to guide the airflow inside the electrical control box 2;

[0039] The electronic control board 3 is embedded in the electronic control box 2 through the mounting port 22 on one side.

[0040] The heat dissipation component 4 is located outside the control box 2, with its air outlet directly facing the air inlet 23 of the control box 2, forming directional airflow. After the airflow enters the control box 2 through the air inlet 23, it is guided to the control board 3 by the air guide component 5. The heat is carried away by the heat exchange between the control board 3 and the airflow. The heated air flows to the air outlet 21 and is finally discharged to the outside through the air outlet 21 of the control box 2 and the heat dissipation port 11 of the partition 1, forming a complete airflow convection path and achieving efficient heat dissipation of the control board 3.

[0041] The partition plate 1 can be made of aluminum alloy, which has good thermal conductivity and light weight, which is beneficial to the stability and heat dissipation efficiency of the overall heat dissipation structure; the heat dissipation vent 11 can be designed as a rectangle, and the specific size is determined according to the actual heat dissipation requirements; the heat dissipation vent 11 can be formed on the partition plate 1 by stamping process to ensure that the edges of the heat dissipation vent 11 are smooth and avoid affecting the airflow; the air outlet 21 and the air inlet 23 can be designed as rectangles, and the size is determined according to the parameters of the heat dissipation component 4 and the air guiding component 5.

[0042] Sealing rubber strips can be installed on the edges of the air outlet 21 and the air inlet 23 to prevent dust and moisture from entering the interior of the electrical control box 2.

[0043] Specifically, the airflow guiding component 5 includes an airflow guiding plate 51, which is disposed on the side of the electrical control box 2 opposite to the air inlet 23. The airflow guiding plate 51 gradually tilts from its top to its bottom towards the air inlet 23 to guide the airflow entering from the air inlet 23 to flow towards the air outlet 21.

[0044] The inclined design of the air deflector 51 can accurately guide the airflow direction. When the heat dissipation component 4 blows air into the air inlet 23, after the air enters the electrical control box 2, due to the inclined angle of the air deflector 51, the airflow will flow towards the air outlet 21 along the guiding direction of the air deflector 51; this allows the air to flow more evenly and effectively over the electrical control board 3, enhancing the heat dissipation effect, avoiding the formation of turbulence or dead zones in the airflow within the electrical control box 2, and improving the heat dissipation efficiency.

[0045] Specifically, the bottom of the electrical control box 2 is provided with a drain hole 24.

[0046] When water accumulates inside the electrical control box 2, the water will flow to the bottom of the electrical control box 2 due to gravity and be discharged to the outside of the electrical control box 2 through the drain hole 24. The drain hole 24 can drain the water inside the electrical control box 2 in a timely manner, preventing the water from damaging the electrical control board 3, such as causing short circuits or corrosion, improving the waterproof performance and reliability of the heat dissipation structure, and extending the service life of the equipment.

[0047] Specifically, the electronic control board 3 is provided with multiple heat dissipation fins 31, which are evenly distributed on the surface of the electronic control board 3 facing the air outlet 21.

[0048] Multiple heat dissipation fins 31 are evenly installed on the surface of the control board 3 facing the air outlet 21. The heat dissipation fins 31 can be fixed to the control board 3 by welding, embedding or other methods. When air flows through the control board 3 in the control box 2, the heat dissipation fins 31 increase the contact area between the control board 3 and the air, accelerate the heat dissipation speed, and enable the heat to be transferred from the control board 3 to the air more quickly, thereby improving the heat dissipation efficiency of the control board 3.

[0049] Specifically, the size of the heat dissipation vent 11 is smaller than the size of the air outlet 21.

[0050] The size of the heat dissipation vent 11 is smaller than that of the air outlet 21. When hot air flows from the air outlet 21 to the heat dissipation vent 11, the larger air outlet 21 and the smaller heat dissipation vent 11 will cause the hot air to flow faster when passing through the heat dissipation vent 11, which is more conducive to the exhaust of hot air, enhances the ventilation effect of the heat dissipation structure, and further improves the heat dissipation efficiency.

[0051] Specifically, the heat dissipation component 4 includes a fan 41, which is mounted on the electrical control box 2, and the air intake surface of the fan 41 covers the air inlet 23; the axis of the fan 41 coincides with the central axis of the air inlet 23.

[0052] The fan 41 in the heat dissipation assembly 4 can be an axial fan 41, which has a high air volume and pressure, and can effectively blow air into the electrical control box 2. The fan 41 is installed on the electrical control box 2 by bolts or clips, ensuring that the fan 41 completely covers the air inlet 23, and the axis of the fan 41 coincides with the central axis of the air inlet 23. When the fan 41 is started, the airflow generated by the fan 41 will directly and concentratedly enter the electrical control box 2 from the air inlet 23 along the axial direction. And because the axis of the fan 41 coincides with the central axis of the air inlet 23, the fan 41 is installed vertically, which effectively reduces the possibility of liquid entering the fan 41, and its waterproof performance is better.

[0053] Specifically, there are multiple air inlets 23 and multiple fans 41.

[0054] The layout of the air inlet 23 and the fan 41 is designed according to the size and shape of the electrical control box 2 to ensure that the airflow can enter the interior of the electrical control box 2 evenly; multiple fans 41 can use the same model and parameters to ensure that they can work together to provide stable air volume and pressure; the setting of multiple air outlets 21 and fans 41 increases the air intake and exhaust volume, which can dissipate the heat generated by the electrical control board 3 more quickly, further improving the heat dissipation efficiency, and is suitable for electrical control boards 3 with large heat generation.

[0055] Specifically, the air outlet 21 is located above the air inlet 23.

[0056] The air outlet 21 is higher than the air inlet 23. According to the thermodynamic principle of hot air rising, cold air will enter the electrical control box 2 from the lower air inlet 23, absorb the heat from the electrical control board 3 and become hot air. The hot air will naturally rise and be discharged from the higher air outlet 21. This height difference design can effectively enhance air convection without additional power equipment, naturally forming good air convection and improving heat dissipation efficiency. Since the airflow eventually flows out from the heat dissipation vent 11, the height difference between the heat dissipation vent 11 and the air outlet 21 can be adjusted by adjusting the relative position of the partition 1 and the electrical control box 2 in the vertical direction, thereby indirectly adjusting the height difference between the air inlet 23 and the heat dissipation vent 11, thus optimizing the air convection effect. The height difference can be determined according to the size of the electrical control box 2 and the heat dissipation requirements.

[0057] Specifically, the heat dissipation structure further includes connecting bolts; the partition plate 1 is provided with a first bolt hole, and the electrical control box 2 is provided with a second bolt hole; the connecting bolts pass through the first bolt hole and the second bolt hole to connect the partition plate 1 and the electrical control box 2.

[0058] The middle partition 1 and the electrical control box 2 are connected by connecting bolts, which ensures the stability of the connection between the two and ensures that the air outlet 21 can accurately cover the heat dissipation port 11. This avoids problems such as air leakage caused by loose connection, improves the overall stability and sealing of the heat dissipation structure, and thus ensures the heat dissipation effect.

[0059] An air conditioner includes a housing for mounting a fan, and the air conditioner also includes a heat dissipation structure as described in any of the preceding claims; a partition 1 is disposed within the housing and the partition 1 divides the internal space of the housing into a fan side and an electrical control side, and an electrical control box 2 is mounted on the electrical control side.

[0060] The preferred embodiments of the present invention have been described in detail above, but the present disclosure is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present disclosure.
