[0002] The demand for side-exhaust units with small shells and high power is becoming more and more common, but the electrical box is located in the sealed cavity inside the unit. The wind field in the sealed cavity is weak and messy, and the overall heat dissipation effect is poor, especially for high-power devices such as IPM modules. Heat dissipation is difficult. If the temperature of components is too high for a long time or exceeds its maximum temperature limit, it is easy to cause damage to the components and lead to air-conditioning failure.

[0003] The prior art discloses an electronic control heat dissipation structure for an air conditioner outdoor unit, which mainly involves a first heat dissipation hole on a middle partition, a heat dissipation cavity on the back of an electrical box, and a second heat dissipation hole in an inner cavity of the electrical control box to form a heat dissipation duct. The first heat dissipation hole on the middle partition is arranged opposite to the second heat dissipation hole on the electrical box. Since water easily enters the heat dissipation hole on the middle partition, the main board inside the electrical box becomes damp and is prone to short circuits and other electrical safety problems. Secondly, the unit has many air ducts and the air volume cannot be concentrated, so it cannot effectively take away the heat of the heating components inside the electrical control box, and the heat dissipation effect is average.

[0032] The utility model provides an outdoor unit heat dissipation structure, an air conditioner outdoor unit and an air conditioner which have good heat dissipation effect and avoid short circuit caused by moisture in internal heating components.

[0033] Combine the following Figure 1 to Figure 5The technical solution provided by the utility model is described in more detail.

[0034] The utility model provides an outdoor unit heat dissipation structure, comprising a middle partition 10, an electrical box 11 mounted on the middle partition 10, and a heating component 12 embedded in the inner cavity of the electrical box 11;

[0035] The middle partition 10 is provided with a first heat dissipation window 15, and the first side wall 13 of the electrical box 11 close to the first heat dissipation window 15 is provided with a second heat dissipation window 16, and the second heat dissipation window 16 communicates with the first heat dissipation window 15 and the inner cavity of the electrical box 11;

[0036] The first side wall 13 and the middle partition board 10 are disposed at an angle A, and a projection of the second heat dissipation window 16 on the middle partition board 10 does not overlap with the first heat dissipation window 15 .

[0037] The utility model provides a heat dissipation structure for an outdoor unit, wherein a first heat dissipation window 15 is arranged on a middle partition 10, and a second heat dissipation window 16 is arranged on a first side wall 13 of an electrical box 11, wherein the second heat dissipation window 16 is used to connect the first heat dissipation window 15 with the inner cavity of the electrical box 11, and when the fan of the unit is running, a negative pressure effect is generated, and the wind in the unit passes through the inner cavity of the electrical box 11, the first heat dissipation window 15 and the second heat dissipation window 16 and is then discharged by the fan, and in the process of wind discharge, the heat of the heating component 12 in the electrical box 11 is taken away, thereby achieving heat dissipation and cooling of the heating component 12 in the electrical box 11, and solving the heat dissipation problem of the electrical box 11.

[0038] In addition, the first side wall 13 is set at an angle A with the middle partition 10, and the projection of the second heat dissipation window 16 on the middle partition 10 does not overlap with the first heat dissipation window 15. Even if rainwater enters the first heat dissipation window 15, it will not directly enter the inner cavity of the electrical box 11, thereby avoiding the problem of short circuit caused by moisture in the internal heating component 12.

[0039] It is understandable that a heating component 12 is provided in the inner cavity of the electrical box 11. The heating component 12 generally includes a circuit board, an electrolytic capacitor, a power device, etc. The heating component 12 generates a lot of heat. Unsatisfactory heat dissipation effect in the electrical box 11 may cause abnormalities in the unit. By providing a first heat dissipation window 15 on the middle partition 10 and a second heat dissipation window 16 on the electrical box 11, the negative pressure effect when the fan is running can be utilized to discharge the heat in the electrical box 11, and the flow of wind field can be utilized to take away the heat of the heating component 12, thereby improving the heat dissipation effect.

[0040] Taking into account the different heat generation, temperature resistance and heat dissipation requirements of different heating elements in the heating component 12, for example, the driving board, the filter board and the like have higher heat dissipation requirements, they are arranged close to the first heat dissipation window 15; therefore, it is necessary to perform rational zoning settings according to the different characteristics of the heating components 12 in the electrical box 11, so as to achieve the best heat dissipation effect.

[0041] In some embodiments of the present invention, the second heat dissipation window 16 is disposed at a position higher than or equal to a position of important heat-generating components in the heat-generating assembly 12 in the electrical box 11 .

[0042] In some of the above-mentioned embodiments of the utility model, since the important heat-generating components in the heating assembly 12 in the electrical box 11 have a greater heat dissipation demand, when setting the second heat dissipation window 16, it is preferred that the setting position of the second heat dissipation window 16 be set to be higher than or equal to the setting position of the important heat-generating components in the heating assembly 12 in the electrical box 11, thereby ensuring that the wind can pass through the important heat-generating components of the heating assembly 12 in the electrical box 11 and then be discharged after the second heat dissipation window 16 and the first heat dissipation window 15, so as to better solve the heat dissipation problem of the electrical box 11 and realize cooling of the electrical box 11 by using the wind field.

[0043] It can be understood that when setting the position of the second heat dissipation window 16, by setting important heat-generating components on the wind flow path, it is ensured that the heat of the important heat-generating components can be taken away immediately, thereby improving the heat dissipation effect. Setting the position of the second heat dissipation window 16 higher than or equal to the setting position of the important heat-generating components can ensure that the important heat-generating components are set on the wind flow path.

[0044] In some embodiments of the utility model, the electrical box 11 includes a first side wall 13 and a second side wall 14, the first side wall 13 and the second side wall 14 are arranged in an L-shaped structure, the heating component 12 is arranged on the first side wall 13 and the second side wall 14, and the second heat dissipation window 16 is arranged on the side of the first side wall 13 close to the second side wall 14.

[0045] In some of the above-mentioned embodiments of the utility model, the electrical box 11 includes a first side wall 13 and a second side wall 14, and the first side wall 13 and the second side wall 14 are arranged in an L-shaped structure. The heating component 12 is arranged on the first side wall 13 and the second side wall 14. Through the arrangement of the first side wall 13 and the second side wall 14, the heating component 12 can be arranged on the first side wall 13 and the second side wall 14 respectively, thereby avoiding the problem of heat concentration caused by the concentrated arrangement of the heating component 12, which is beneficial to heat dissipation; the first side wall 13 and the second side wall 14 can also be used to reasonably divide the heating component 12, and rationally arrange the heating components in the heating component 12 in zones, so as to cool down the concentrated heat source by the wind field and improve the heat dissipation effect.

[0046] The second heat dissipation window 16 is arranged on a side of the first side wall 13 close to the second side wall 14, that is, the second heat dissipation window 16 is arranged near the intersection of the first side wall 13 and the second side wall 14. Wind can pass through the heat-generating components on the first side wall 13 and the second side wall 14 and then be discharged from the second heat dissipation window 16, which effectively solves the problem of heat dissipation of the electrical box 11.

[0047] It can be understood that when the important heat-generating components in the heat-generating assembly 12 are arranged at a lower position and are arranged close to the second heat-dissipating window 16, the heat dissipation effect can be improved; when the important heat-generating components are arranged at a lower position, the position of the second heat-dissipating window 16 can be set lower. Since the second heat-dissipating window 16 is higher than or equal to the setting position of the important heat-generating components, it can ensure that the heat of the important heat-generating components is discharged immediately, and the heat dissipation effect can also be improved; and the position of the second heat-dissipating window 16 can be set lower, and the size of the second heat-dissipating window 16 can be set larger to improve the heat dissipation effect.

[0048] In some embodiments of the present invention, an angle A between the first side wall 13 and the middle partition 10 is 60-120 degrees.

[0049] In some of the above-mentioned embodiments of the utility model, the first side wall 13 is arranged at an angle with the middle partition 10, which can prevent the moisture entering through the first heat dissipation window 15 on the middle partition 10 from directly entering the inner cavity of the electrical box 11 through the first side wall 13, thereby avoiding the problem of short circuit caused by moisture in the internal heating component 12.

[0050] In some embodiments, the first side wall 13 is vertically arranged to the middle partition 10, the heat dissipation holes on the first heat dissipation window 15 and the second heat dissipation window 16 are vertically distributed, and the first heat dissipation window 15 and the second heat dissipation window 16 do not overlap. At this time, the problem of short circuit caused by moisture in the internal heating component 12 can be well avoided.

[0051] In some embodiments, the first side wall 13 and the middle partition 10 are set at an acute angle. At this time, in order to ensure that the projection of the second heat dissipation window 16 on the middle partition 10 does not overlap with the second heat dissipation window 16, it is necessary to stagger the first heat dissipation window 15 and the second heat dissipation window 16 to ensure that moisture does not directly enter the inner cavity of the electrical box 11.

[0052] In some embodiments, the first side wall 13 and the middle partition 10 are set at an obtuse angle. At this time, the second heat dissipation window 16 and the first heat dissipation window 15 will not overlap at all, which can effectively avoid the problem of short circuit caused by moisture in the internal heating component 12.

[0053] Considering the internal space and layout of the outdoor unit, the angle A between the first side wall 13 and the middle partition 10 is preferably selected to be 60-120 degrees.

[0054] In some embodiments of the present invention, an air guide component 17 is further included. The air guide component 17 is disposed at the bottom of the electrical box 11 , and the air guide component 17 is connected to the inner cavity of the electrical box 11 and the air inlet window 18 .

[0055] In some of the above-mentioned embodiments of the utility model, an air guide component 17 is provided between the air inlet window 18 and the inner cavity of the electrical box 11. The air guide component 17 is used to connect the air inlet window 18 and the inner cavity of the electrical box 11. When the fan is running, it can ensure that the airflow entering through the air inlet window 18 can be gathered by the air guide component 17 and flow into the inner cavity of the electrical box 11, thereby changing the problem of a messy and weak wind field inside the existing unit.

[0056] In some specific implementations of the present utility model, the air guide assembly 17 includes an air guide pipe 19;

[0057] The first end of the air guide 19 is provided with an air outlet 20, the upper air outlet of the air outlet 20 is connected to the inner cavity of the electrical box 11, and the diameter of the lower air outlet of the air outlet 20 connected to the first end of the air guide 19 is smaller than the diameter of the upper air outlet of the air outlet 20;

[0058] An air inlet pipe 21 is disposed at the second end of the air guide pipe 19 , and the air inlet pipe 21 is communicated with the air inlet window 18 .

[0059] In some of the above-mentioned embodiments of the utility model, the air guide component 17 includes an air guide duct 19, an air outlet duct 20 and an air inlet duct 21. The air inlet duct 21 is connected to the air inlet window 18, and the air outlet duct 20 is connected to the inner cavity of the electrical box 11. The air outlet duct 20 has a larger diameter facing the upper air outlet of the inner cavity of the electrical box 11, which can guide the airflow to the inner cavity of the electrical box 11, ensure the heat dissipation of the heating component 12 in the inner cavity of the electrical box 11, improve the heat dissipation effect, and make the heat dissipation more efficient.

[0060] Furthermore, the air inlet window 18 is provided with a plurality of strip-shaped heat dissipation holes, and the width of the strip-shaped heat dissipation holes does not exceed 3 mm, thus meeting the requirements of insect and rodent prevention.

[0061] In some specific implementations of the present invention, the vertical cross-section of the air outlet duct 20 is a trapezoidal structure. The trapezoidal structure has a good flow guiding effect, ensuring that the airflow can be guided into the inner cavity of the electrical box 11.

[0062] In some specific implementations of the present invention, a heat dissipation fan is further provided in the inner cavity of the electrical box 11. The heat dissipation in the electrical box 11 is accelerated by the heat dissipation fan.
