[0023] In order to explain in detail the possible application scenarios, technical principles, specific solutions that can be implemented, and the purpose and effects of this application, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of this application and are therefore only examples and are not intended to limit the scope of protection of this application.

[0024] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more features.

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0026] The embodiments of the present application provide an electronic control component and an air conditioner to solve the problem that the existing radiator is difficult to cool the electronic control component to the designed temperature.

[0027] An embodiment of the present application provides an electric control component, including an electric control box 1 and an electric control unit 2. The electric control box 1 is provided with a first air outlet 115 and a second air outlet 122. An air duct is provided inside the electric control box 1. The first air outlet 115 and the second air outlet 122 are both connected to the air duct. The electric control unit 2 is at least partially arranged in an area in the air duct between the first air outlet 115 and the second air outlet 122.

[0028] By setting the first air outlet 115 and the second air outlet 122, and making the first air outlet 115 and the second air outlet 122 connected to the air duct, wind can enter the air duct from one of the air outlets and flow out of the air duct from the other air outlet; since the electrical control component 2 is at least partially set in the air duct, the heat generated by the electrical control component 2 can be dissipated by wind convection, thereby improving the heat dissipation effect of the electrical control component 2 and solving the problem that the radiator 22 is difficult to reduce the electrical control component to the design temperature.

[0029] The electric control box 1 includes a box cover 11 and a box body 12. The box cover 11 includes a top cover 111 and a heat dissipation cover 112. The top cover 111 is arranged opposite the box body 12, and the heat dissipation cover 112 is arranged between the top cover 111 and the box body 12. The top cover 111 and the heat dissipation cover 112 are both detachably connected to the box body 12 via a snap-fit structure, and the top cover 111 and the heat dissipation cover 112 are detachably connected via bolts. Specifically, the snap-fit structure includes buckle holes 113 provided on the side panels of the top cover 111 and the heat dissipation cover 112, and buckle blocks 121 provided on the side walls of the box body 12. An inclined surface is provided between the top side and the outer side of the buckle block 121 to facilitate buckling the buckle block 121 into the buckle holes 113.

[0030] The electrical control unit 2 includes an electrical control board 21 and a heat sink 22. The electrical control board 21 is disposed within the box body 12. The heat sink 22 is disposed on the electrical control board 21. The heat sink 22 includes a heat dissipation substrate 221 and heat dissipation fins 222 disposed on the heat dissipation substrate 221. The heat dissipation substrate 221 is disposed on the electrical control board 21 and is located in the air duct. The heat dissipation fins 222 extend out of the electrical control box 1 through the heat dissipation window 114. By dissipating the heat dissipation substrate 221 within the air duct and extending the heat dissipation fins 222 out of the electrical control box 1 through the heat dissipation window 114, multiple heat dissipation fins 222 are spaced apart along the extension direction of the air duct. This allows the electrical control board 21 to not only transfer heat to the outside through the heat sink 22 but also dissipate heat through air convection, thereby controlling the temperature of the electrical control board 21 to the designed temperature. In this embodiment, air can be supplied to the air duct from one of the air vents and exhausted from the other, or air can be supplied to the air duct from both air vents and exhausted from the heat dissipation window 114, depending on actual needs.

[0031] In some embodiments of the present application, a sealing ring (not shown in the figure) is provided on the heat dissipation substrate 221, which connects the heat dissipation substrate 221 and the heat dissipation cover 112, thereby reducing the entry of foreign matter into the interior of the electrical box through the heat dissipation window 114, and in this embodiment, air needs to be supplied to the air duct from one of the air outlets and then exhausted from the other air outlet.

[0032] The first air vent 115 is provided at the top of the box cover 11, and the second air vent 122 is provided at the bottom of the box body 12. The first air vent 115 is provided on one side of the box cover 11 in the first direction, while the second air vent 122 is provided on the side of the box body 12 opposite to the first direction. By arranging the first air vent 115 at an upper and oblique position on one side of the width of the electrical box and the second air vent 122 at a lower and oblique position on one side of the width of the electrical box, the length of the wind's path is increased, allowing the wind to fully remove heat from the connection between the radiator 22 and the electronic control board 21. The first air vent 115 includes a plurality of first air holes provided on the box cover 11, and the second air vent 122 includes a plurality of second air holes provided on the box body 12. The diameter of the first air holes is D1, and the diameter of the second air holes is D2, with 1mm≤D1≤3mm and 1mm≤D2≤3mm. The preferred values of D1 and D2 are both 1.5 mm. When D1 is less than 1 mm or D2 is less than 1 mm, the air outlet is too small, which is not conducive to air flowing into the air duct. When D1 is greater than 3 mm or D2 is greater than 3 mm, the seal is too large, making it easy for foreign matter to enter the electric control box 1.

[0033] In this embodiment, the cover 11 is made of metal and has a thickness of 0.6 mm, while the body 12 is made of plastic and has a thickness of 2.7 mm. The metal cover 11 improves the passive heat dissipation capability of the electrical box, while the plastic body 12 improves the structural strength of the electrical box.

[0034] The embodiment of the present application further provides an air conditioner, which includes the electronic control assembly described above. Since the air conditioner includes the electronic control assembly described above, and because it has at least some or all of the beneficial effects of the electronic control assembly described above, they will not be described in detail here.

[0035] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0036] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
