[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0022] The embodiment of the present application provides an electric control box to solve the problem of high temperature damage to components inside the electric control box.

[0023] In the embodiments of this application, Figure 1 As shown, the electric control box includes a box body 1 and a fan assembly, and the fan assembly is arranged in the box body 1; the fan assembly includes an air guide 2 and an air guide structure 3 arranged relatively spaced apart, and the air guide 2 is used to drive the air flow in the box body 1; the air outlet side of the air guide 2 is arranged toward the air inlet side of the air guide structure 3, so that the air outlet airflow of the air guide 2 drives the air guide structure 3 to guide the air, and the air inlet side and the air outlet side of the air guide structure 3 are vertical or inclined at an angle.

[0024] It is understood that the airflow generated by the outlet side of the air guide 2 drives the air guide structure 3, thereby saving the drive source of the air guide structure 3, reducing costs, avoiding the introduction of new heat sources into the box body 1, and providing greater installation freedom. The air inlet and outlet sides of the air guide structure 3 are perpendicular or tilted at an angle, which changes the direction of the airflow, facilitates the formation of a flow field within the box body 1, improves temperature uniformity, avoids high temperature accumulation, and protects components.

[0025] In some embodiments, as Figure 1 As shown, the air guide 2 and the air guide structure 3 are respectively disposed on opposite sides of the box body 1 along a first direction, and the air outlet direction of the air guide structure 3 is perpendicular to or inclined at an angle to the first direction. For example, the first direction can be the length, width, or height of the box body 1, or a direction inclined to at least one of the above directions. It is understood that by designing the relative position of the air guide 2 and the air guide structure 3, the flow rate of the airflow within the box body 1 can be accelerated.

[0026] In some embodiments, as Figure 1 and Figure 2As shown, the box body 1 is provided with an air outlet 12, and the air outlet 12 is located in the air outlet direction of the air guide structure 3. The position of the air outlet 12 is set according to the flow direction of the air flow, so that the hot air in the box body 1 is discharged faster.

[0027] In some embodiments, as Figure 1 and Figure 2 As shown, the box body 1 is provided with an air inlet 11 , and the air inlet side of the air guide 2 faces the air inlet 11 .

[0028] In some embodiments, as Figure 1 and Figure 2 As shown, the air outlet 12 is close to the upper side wall of the box body 1. It should be noted that the upper side wall of the box body 1 refers to the side wall of the box body 1 opposite to the direction of gravity. According to the density of hot and cold air, the air outlet 12 is set on the upper side wall of the box body 1 to increase the exhaust speed of the heated air.

[0029] In some embodiments, as Figure 1 As shown, at least two mounting portions are provided in the box body 1 for mounting heating elements, one mounting portion being located between the air outlet side of the air guide 2 and the air inlet side of the air guide structure 3, and the other mounting portion being located between the air outlet side of the air guide 2 and the air inlet side of the air guide structure 3. It should be noted that the heating element may refer to an electronic component that generates heat during operation, such as a reactor 4 and a drive board 5. For example, the heating element may be provided on different mounting portions according to the amount of heat generated, so as to achieve precise heat dissipation for different amounts of heat generated.

[0030] In some embodiments, as Figure 2 As shown, at least two mounting portions are provided within the box body 1 for mounting heating elements. One mounting portion is located between the air outlet side of the air guide 2 and the air inlet side of the air guide structure 3, and the other mounting portion is located on the air outlet side of the air guide structure 3. It is understood that one mounting portion can be used to mount multiple heating elements. Placing the mounting portion for mounting multiple heating elements between the air outlet side of the air guide 2 and the air inlet side of the air guide structure 3 has a better heat dissipation effect. The multiple heating elements here can be multiple main control boards 8; the other mounting portion can be used to mount the reactor 4.

[0031] Furthermore, along the air outlet direction of the air outlet side of the air guide structure 3 are another mounting portion and the air outlet 12 in sequence.

[0032] In some embodiments, as Figure 1 As shown, the electric control box also includes a reactor 4 and a drive plate 5; along the air outlet side of the air guide 2 pointing to the air inlet side of the air guide structure 3, two mounting parts are sequentially arranged, and the reactor 4 and the drive plate 5 are respectively arranged on the two mounting parts. It can be understood that the heating elements in this embodiment are the reactor 4 and the drive plate 5. For example, as Figure 1As shown, along the direction from the outlet side of the air guide 2 to the inlet side of the air guide structure 3, the reactor 4 and the drive plate 5 are arranged in that order. Since the heat generated by the reactor 4 is higher than that generated by the drive plate 5, arranging them in the above positions can achieve precise heat dissipation. Along the direction from the outlet side of the air guide 2 to the inlet side of the air guide structure 3, the drive plate 5 and the reactor 4 can also be arranged in that order.

[0033] Furthermore, the box body 1 is provided with an air inlet 11, and the air inlet side of the air guide 2 is arranged toward the air inlet 11; two drive plates 5 are provided, pointing along the air outlet side of the air guide 2 toward the air inlet side of the air guide structure 3, which are the reactor 4 and one drive plate 5 in sequence; the other drive plate 5 and the air outlet 12 are arranged in sequence in the air outlet direction of the air outlet side of the air guide structure 3.

[0034] In some embodiments, as Figure 1 and Figure 2 As shown, the driving board 5 is provided with a capacitor 6 and an electromagnetic coil 7. It is understandable that the original capacitor 6 and electromagnetic coil 7 in the electric control box are arranged on the driving board 5 to achieve simultaneous heat dissipation with the driving board 5.

[0035] In some embodiments, as Figure 1 and Figure 2 As shown, the reactor 4 is located on the outlet side of the air guide structure 3; the outlet side of the air guide member 2 and / or the inlet side of the air guide structure 3, facing between the capacitor 6 and the electromagnetic coil 7. Exemplarily, facing between the capacitor 6 and the electromagnetic coil 7 is: the outlet side of the air guide member 2 and the inlet side of the air guide structure 3, or the outlet side of the air guide member 2 or the inlet side of the air guide structure 3. It is understood that such arrangement of the capacitor 6 and the electromagnetic coil 7 can avoid the airflow from the air guide member 2 to the air guide structure 3, ensuring a stable flow direction of the flow field.

[0036] In some embodiments, as Figure 1 and Figure 2 As shown, the main control board 8 is also included, and is located around the reactor 4. It is understood that the temperature of the main control board 8 is lower than that of other components, so the heat dissipation requirement is relatively low. The heat dissipation requirement can be met by using the airflow flowing through the components that generate more heat.

[0037] In some embodiments, the air guide structure 3 includes a housing and blades, and the blades are centrifugal blades. It is understood that the centrifugal blades change the airflow direction on the air inlet and outlet sides of the air guide structure 3 to form a flow field.

[0038] Exemplarily, the air inlet side of the air guide structure 3 is in the axial direction or radial direction of the centrifugal fan blades, preferably in the axial direction of the centrifugal fan blades.

[0039] In some embodiments, the air guide member 2 includes an axial flow fan and a motor, and the motor is used to drive the axial flow fan to rotate.
