[0058] 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. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0059] In the present application, the term "plurality" refers to two or more. In addition, it should be understood that in the description of the present application, the terms "first", "second", etc. are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0060] In the description of the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0061] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 A heat dissipation mechanism 100 provided in an embodiment of the present application is shown. The heat dissipation mechanism 100 can be applied to an inverter (not shown). The inverter can be applied to energy storage devices and photovoltaic devices.

[0062] In the embodiment of the present application, the length direction of the heat dissipation mechanism 100 can be defined as the first horizontal direction, the width direction as the second horizontal direction, and the height direction as the vertical direction. For example, the first horizontal direction can be as follows: Figure 1 and Figure 2 The X direction shown, the second horizontal direction can be as follows Figure 1 and Figure 2 The Y direction is shown, and the vertical direction can be as follows Figure 1 and Figure 2 The Z direction is shown. The side that the X-direction arrow faces away from is the first side of the heat dissipation mechanism 100 and its components, and the side that the X-direction arrow faces is the second side of the heat dissipation mechanism 100 and its components.

[0063] Please also read Figure 3 In one embodiment, the inverter may include a first electronic mechanism (not shown) and two second electronic mechanisms (not shown). The heat dissipation mechanism 100 may include a bottom frame 10. A receiving space (not shown) may be provided in the bottom frame 10, and the first electronic mechanism may be received in the receiving space and fixedly connected to the bottom frame 10. A first area 11, a second area 12 and a third area 13 may be provided on the bottom frame 10, and the first area 11, the third area 13 and the second area 12 are arranged in the first horizontal direction. The width of the third area 13 in the second horizontal direction may be less than the length of the first area 11 and the second area 12 in the second horizontal direction. The two second electronic mechanisms may be provided in the first area 11 and the second area 12, respectively, and the second electronic mechanisms may be fixedly connected to the bottom frame 10.

[0064] It can be understood that the two sides of the bottom frame 10 in the first horizontal direction can be the first side and the second side respectively, wherein the first area 11 is located on the first side of the bottom frame 10 and on the first side of the heat dissipation mechanism 100; the second area 12 is located on the second side of the bottom frame 10 and on the second side of the heat dissipation mechanism 100. The third area 13 is located between the first area 11 and the second area 12.

[0065] It can be understood that the bottom frame 10 can accommodate the first electronic mechanism and receive the second electronic mechanism. The first electronic mechanism and the second electronic mechanism have circuit structures and are used to implement at least part of the functions of the inverter, such as filtering function, frequency modulation function, DC-AC conversion function, etc. Among them, the first electronic mechanism can be a circuit board connected to multiple electronic components in the inverter, and the second electronic mechanism can be an inductor in the inverter.

[0066] In the embodiments of the present application, there is no specific limitation on the fixing method during the fixed connection and fixed installation. For example, the fixing method may include screw fixing, bolt fixing, welding fixing, etc.

[0067] In some embodiments, the heat dissipation mechanism 100 may further include a blowing member 20 and a plurality of wind guide components 30. The blowing member 20 is located on one side of the bottom frame 10 in the second horizontal direction, and the blowing member 20 is spaced apart from the third area 13 in the second horizontal direction. The blowing member 20 is fixedly connected to the bottom frame 10. The blowing member 20 can blow air toward the third area 13. The plurality of wind guide components 30 are disposed on the bottom frame 10 and are located between the third area 13 and the blowing member 20. The plurality of wind guide components 30 are spaced apart in the first horizontal direction.

[0068] Please also read Figure 4 Each air guide assembly 30 includes an air guide member 31 and a first driving member 32 ( Fig. 9 The air guide 31 can block part of the air flow blown out by the blowing member 20 by rotating, and guide the air flow to continue to flow in the direction of the air guide 31. The first driving member 32 can be accommodated in the accommodation space, and can be fixedly connected to the air guide 31. The first driving member 32 can drive the air guide 31 to rotate.

[0069] It can be understood that the air guide 31 can be in the shape of a plate, or part of the structure on the air guide 31 is in the shape of a plate. The rotation of the air guide plate 311 can adjust the flow direction of the airflow, thereby changing the direction of the air duct in the heat dissipation mechanism 100 for blowing heat away from the heat dissipation mechanism 100. The air guide 31 may include a first end close to the blowing member 20 in the second horizontal direction and a second end close to the third area 13. The straight line direction where the first end of the air guide 31 and the second short line are connected is the length direction of the air guide 31. When the air guide 31 is at the initial angle, the length direction of the air guide 31 coincides with the second horizontal direction. At this time, the air guide 31 may not block the gas blown out by the blowing member 20, so that the gas can flow to the third area 13.

[0070] Figure 3 The air guide 31 located on the first side is at a first angle. When the air guide 31 rotates from the initial angle to the first angle, the first end of the air guide 31 gradually approaches the first side of the bottom frame 10 in the first horizontal direction, and the second end of the air guide 31 gradually approaches the second side of the bottom frame 10 in the first horizontal direction. When the air guide 31 is at the first angle, the air guide 31 is tilted and can block the airflow blown out by the blowing member 20, so that the airflow deviates from the direction of the blowing member 20 toward the third area 13. The air guide 31 can guide the airflow to flow in the direction from the first end of the air guide 31 to the second end; when the air guide 31 is at the first angle, the second end of the air guide 31 faces the first side of the heat dissipation mechanism 100, and the air guide 31 can guide the airflow to flow to the first side of the heat dissipation mechanism 100. Among the multiple air guides 31, some of the air guides 31 located on the first side in the first horizontal direction can guide the airflow to flow to the first area 11 when they are at the first angle.

[0071] Figure 3 The air guide member 31 located on the second side is at a second angle. When the air guide member 31 rotates from the initial angle to the second angle, the first end of the air guide member 31 gradually approaches the second side of the base frame 10 in the first horizontal direction, and the second end of the air guide member 31 gradually approaches the first side of the base frame 10 in the first horizontal direction. When the air guide member 31 is at the first angle, the air guide member 31 is tilted and can block the airflow blown out by the blowing member 20, so that the airflow deviates from the direction of the blowing member 20 toward the third area 13. At this time, the second end of the air guide member 31 is toward the second side of the heat dissipation mechanism 100, and the air guide member 31 can guide the airflow to flow to the second side of the heat dissipation mechanism 100. Among the multiple air guide members 31, when some of the air guide members 31 located on the second side in the first horizontal direction are at the second angle, the airflow can be guided to flow to the second area 12.

[0072] In this way, each air guide member 31 can rotate separately or simultaneously, thereby changing the flow direction of the airflow blown out by the blowing member 20, so that the airflow can pass through any one or more areas in the first area 11, the second area 12 and the third area 13 that need to dissipate heat. This can reduce the situation where some areas in the inverter cannot dissipate heat due to being unable to receive the airflow blown out by the blowing member 20, thereby improving the heat dissipation efficiency of the heat dissipation mechanism 100 and the inverter, improving the performance of the inverter, and increasing the service life of the inverter.

[0073] In the embodiment of the present application, there is no specific limitation on the type of the blowing member 20. For example, the blowing member 20 may be, but is not limited to, a fan, a blower, and the like.

[0074] It is understood that the first driving member 32 is an electric or pneumatic member with a rotation driving function. In the embodiment of the present application, there is no specific limitation on the type of the first driving member 32. For example, the first driving member 32 can be, but is not limited to, a motor, a rotary cylinder, etc.

[0075] In the embodiments of the present application, there is no specific limitation on the number of air guide members 31. Figure 2 and Figure 3 As shown, the number of the air guide members 31 may be two, and the two air guide members 31 may be symmetrically arranged according to a surface in which the vertical direction and the second horizontal direction coexist.

[0076] Please also read Figure 5 , for example, Figure 5 As shown, the number of the air guide members 31 may be two, and the two air guide members 31 may be arranged in an array in the first horizontal direction.

[0077] It is understandable that Figure 2 and Figure 3The figure shows a situation where there are two air guides 31 and the two air guides 31 are symmetrically arranged; wherein the air guide 31 located on the first side is at a first angle, and the air guide 31 located on the second side is at a second angle. Among the two air guides 31, the air guide 31 located on the first side faces the first area 11 when it is at the first angle, and can guide the airflow to flow to the first area 11; the air guide 31 located on the second side faces the second area 12 when it is at the second angle, and can guide the airflow to flow to the second area 12.

[0078] The following embodiments are described by way of example based on the case where there are two air guide members 31 .

[0079] In some embodiments, the air guide 31 may include an air guide plate 311, a first reinforcing sheet 312, a second reinforcing sheet 313 and a connecting sheet 314. The air guide plate 311 may be arranged perpendicular to the surface where the first horizontal direction and the second horizontal direction coexist. The air guide plate 311 may block the airflow blown out by the blowing member 20. The connecting sheet 314 is fixedly connected to one end of the air guide plate 311 close to the bottom frame 10 in the vertical direction and is perpendicular to the air guide plate 311. The connecting sheet 314 is rotatably connected to the bottom frame 10. The first reinforcing sheet 312 is fixedly connected to one end of the air guide plate 311 close to the third area 13. The first reinforcing sheet 312 may be arranged at an acute angle with the air guide plate 311 or be flush with the air guide plate 311. The second reinforcing sheet 313 is fixedly connected to one end of the air guide plate 311 close to the bottom frame 10 in the vertical direction and is perpendicular to the air guide plate 311. The first reinforcing sheet 312 is fixedly connected to the second reinforcing sheet 313.

[0080] It can be understood that the rotation of the air guide plate 311 can change the direction of the air duct in the heat dissipation mechanism 100. The connecting piece 314 can provide a connection position for the connection between the air guide member 31 and the bottom frame 10. The first reinforcing piece 312 and the second reinforcing piece 313 can improve the structural strength of the air guide member 31, reduce the probability of the air guide member 31 being deformed or broken due to excessive force due to the high air flow velocity blown by the blowing member 20 and the high pressure on the air guide plate 311, and improve the service life of the air guide member 31.

[0081] In some embodiments, a plurality of limiting posts 14 are convexly provided on the bottom frame 10, and the plurality of limiting posts 14 correspond to the plurality of air guides 31 one by one. A limiting slot 315 is provided on the connecting piece 314 of each air guide 31, and the limiting posts 14 can penetrate the corresponding limiting slot 315. During the rotation of the air guide 31, the limiting posts 14 can rotate relative to the air guide 31, and the limiting members can move in the limiting slot 315. The limiting posts 14 are used to abut against the inner walls at both ends of the limiting slot 315 to limit the rotation angle of the air guide 31.

[0082] It can be understood that the limit groove 315 cooperates with the limit column 14 to limit the rotation angle of the air guide member 31, so as to reduce the probability of the air guide member 31 rotating to completely block the blowing member 20, and reduce the probability of the air guide member 31 rotating too much and guiding the airflow to deviate from the first area 11, the second area 12 and the third area 13, thereby improving the heat dissipation efficiency of the heat dissipation mechanism 100.

[0083] In some embodiments, each wind guide assembly 30 may further include an auxiliary sheet 33 and a second driving member 34 ( Fig. 9 ). The auxiliary sheet 33 is rotatably connected to the corresponding air guide 31 and is located at the second end of the air guide 31. The second driving member 34 is fixedly connected to the air guide 31. The second driving member 34 can drive the auxiliary sheet 33 to rotate relative to the air guide 31. After the auxiliary sheet 33 rotates, it can be arranged parallel to or at an acute angle with the air guide 31. The auxiliary sheet 33 may include a first end close to the blowing member 20 in the second horizontal direction and a second end close to the third area 13.

[0084] It can be understood that the end of the air guide plate 311 close to the blowing member 20 is the first end of the air guide member 31, and is the first section of the air guide plate 311; the end of the air guide member 31 where the first reinforcement plate 312 is located is the second end of the air guide member 31, and the end of the air guide plate 311 connected to the first reinforcement plate 312 is the second end of the air guide plate 311.

[0085] In some cases, when the auxiliary sheet 33 is flush with the air guide 31, the auxiliary sheet 33 is parallel to the air guide plate 311; or in the direction from the first end of the air guide plate 311 toward the second end, the projection of the auxiliary sheet 33 coincides with the projection of the air guide plate 311. At this time, the line connecting the first end and the second end of the auxiliary sheet 33 coincides with or is parallel to the line connecting the first end and the second end of the air guide plate 311.

[0086] In other cases, when the auxiliary sheet 33 is flush with the air guide 31 , the auxiliary sheet 33 is parallel to and in contact with the first reinforcing sheet 312 .

[0087] In the embodiment of the present application, there is no specific limitation on the angle between the auxiliary piece 33 and the air guide plate 311 after the auxiliary piece 33 is rotated. For example, the auxiliary piece 33 may form an angle of 45 degrees with the air guide plate 311 after the auxiliary piece 33 is rotated.

[0088] In some cases, the two air guide members 31 are symmetrically arranged, and the auxiliary piece 33 in the air guide member 31 located on the first side is located on the side of the air guide plate 311 close to the first area 11, and the auxiliary piece 33 in the air guide member 31 located on the second side is located on the side of the air guide plate 311 close to the second area 12.

[0089] When the two air guides 31 are at the initial angle, the auxiliary sheet 33 in each air guide 31 can be flush with the air guide 31, so that the airflow flows to the third area 13. The auxiliary sheet 33 of each air guide 31 can also be rotated to form an acute angle with the air guide plate 311, so as to partially block the airflow flowing toward the third area 13, and guide the blocked airflow to the first area 11 or the second area 12 located on the side of the third area 13.

[0090] When the air guide member 31 located on the first side is at a first angle, the auxiliary sheet 33 can be flush with the air guide member 31, thereby working together with the air guide plate 311 to guide the airflow to the first area 11; when the air guide member 31 located on the first side is at a second angle, the auxiliary sheet 33 can be rotated to form an acute angle with the air guide plate 311. At this time, the auxiliary sheet 33 can face the third area 13, so that when the air guide plate 311 guides the airflow to flow toward the second side of the heat dissipation mechanism 100, part of the airflow is guided to deviate from the guiding direction of the air guide plate 311 and flow to the third area 13.

[0091] When the air guide member 31 located on the second side is at the second angle, the auxiliary sheet 33 can be flush with the air guide member 31, thereby working together with the air guide plate 311 to guide the airflow to the second area 12; when the air guide member 31 located on the second side is at the first angle, the auxiliary sheet 33 can be rotated to form an acute angle with the air guide plate 311. At this time, the auxiliary sheet 33 can face the third area 13, so that when the air guide plate 311 guides the airflow to flow toward the first side of the heat dissipation mechanism 100, part of the airflow is guided to deviate from the guiding direction of the air guide plate 311 and flow to the third area 13.

[0092] In other cases, two air guides 31 are arranged in an array, and the auxiliary pieces 33 in the two air guides 31 are both located on the side of the corresponding air guide plate 311 close to the first area 11 or the second area 12. The following example is taken as an example in which the auxiliary pieces 33 in the two air guides 31 are both located on the side of the corresponding air guide plate 311 close to the first area 11.

[0093] The auxiliary piece 33 in each air guide member 31 can be flush with the air guide member 31 to allow the airflow to flow to the third area 13. The auxiliary piece 33 of the air guide member 31 located on the first side can also be rotated to form an acute angle with the air guide plate 311, thereby partially blocking the airflow flowing toward the third area 13, and guiding the blocked airflow to the first area 11 located on the side of the third area 13.

[0094] When the air guide member 31 located on the first side is at a first angle, the auxiliary sheet 33 can be flush with the air guide member 31, thereby working together with the air guide plate 311 to guide the airflow to the first area 11; when the air guide member 31 located on the first side is at a second angle, the auxiliary sheet 33 can be rotated to form an acute angle with the air guide plate 311. At this time, the auxiliary sheet 33 can face the third area 13, so that when the air guide plate 311 guides the airflow to flow toward the second side of the heat dissipation mechanism 100, part of the airflow is guided to deviate from the guiding direction of the air guide plate 311 and flow to the third area 13.

[0095] When the air guide member 31 on the second side is at an initial angle, the auxiliary sheet 33 can rotate to form an acute angle with the air guide plate 311, and the air guide member 31 can face the third area 13, and the auxiliary sheet 33 faces the first side of the heat dissipation mechanism 100, so that when the air guide plate 311 guides the airflow to flow to the second area 12, part of the airflow is guided to deviate from the guiding direction of the air guide plate 311 and flow toward the first side of the heat dissipation mechanism 100. When the air guide member 31 on the second side is at a first angle, the auxiliary sheet 33 can be flush with the air guide member 31, so as to work together with the air guide plate 311 to guide the airflow to flow toward the first side of the heat dissipation mechanism 100. When the air guide member 31 located on the second side is at the second angle, the auxiliary sheet 33 can be flush with the air guide member 31, thereby working together with the air guide plate 311 to guide the airflow to the second area 12; the auxiliary sheet 33 can also be rotated to form an acute angle with the air guide plate 311. At this time, the auxiliary sheet 33 can be directed toward the third area 13, so that when the air guide plate 311 guides the airflow to flow toward the second side of the heat dissipation mechanism 100, part of the airflow is guided to deviate from the guiding direction of the air guide plate 311 and flow to the third area 13.

[0096] It can be understood that the air guide plate 311 and the auxiliary sheet 33 in the multiple air guide members 31 cooperate with each other, and the air guide plate 311 can form an air duct while partially diverting the air duct through the auxiliary sheet 33, so that the air guide component 30 can simultaneously guide the airflow to the first area 11, the second area 12 and the third area 13, so that the heat dissipation mechanism 100 can control the air guide plate 311 and the auxiliary sheet 33 to be at different angles based on different temperature conditions of the first area 11, the second area 12 and / or the third area 13, thereby generating a variety of air guide schemes that can adapt to a variety of heat dissipation requirements, thereby improving the heat dissipation efficiency of the heat dissipation mechanism 100.

[0097] It is understood that the second driving member 34 is an electric or pneumatic member with a rotation driving function. In the embodiment of the present application, there is no specific limitation on the type of the second driving member 34. For example, the second driving member 34 can be, but is not limited to, a motor, a rotary cylinder, etc.

[0098] It is understood that the rotatable connection can be achieved by a rotating connection member, which is a connection method that allows two components to rotate relative to each other. In the embodiments of the present application, the type of the rotating connection member is not specifically limited. For example, the rotating connection member can be, but is not limited to, a pin, a bearing, a hinge, etc.

[0099] Please also read Figure 6 In some embodiments, the heat dissipation mechanism 100 may further include a heat sink 40, a first cover shell 50, a second cover shell 60 and a protective cover 70. The heat sink 40 is located in the third area 13 and is fixedly mounted on the bottom frame 10. The heat generated by the first electronic mechanism in the accommodation space can be conducted to the heat sink 40 through the portion of the bottom frame 10 located in the third area 13. A plurality of first fins 41 are provided on the heat sink 40. The plurality of first fins 41 all extend along the second horizontal direction, and the plurality of first fins 41 are spaced apart in the first horizontal direction. The heat received by the heat sink 40 can be conducted to the plurality of first fins 41, and the airflow blown out by the blowing member 20 passes through the plurality of first fins 41 located in the third area 13, can absorb the heat on the plurality of first fins 41, and take the heat away from the heat dissipation mechanism 100. In this way, the heat dissipation generated by the first electronic mechanism can be achieved through the heat conduction of the heat sink 40 and the air cooling of the blowing member 20.

[0100] Please also read Figure 7 and Figure 8 , the first housing 50 and the second housing 60 are respectively located on both sides of the radiator 40 in the first horizontal direction, and are respectively located in the first area 11 and the second area 12. The first housing 50 and the second housing 60 can be respectively covered with two second electronic mechanisms. The first housing 50 and the second housing 60 can be fixedly mounted on the bottom frame 10. The heat generated by the two second electronic mechanisms can be respectively conducted to the first housing 50 and the second housing 60. A plurality of second fins 80 are provided on each of the first housing 50 and the second housing 60. The plurality of second fins 80 extend along the second horizontal direction, and the plurality of second fins 80 are spaced apart in the first horizontal direction. The heat absorbed by the first housing 50 and the second housing 60 can be conducted to the corresponding second fins 80, and the airflow blown out by the blowing member 20 can flow to the plurality of second fins 80 located in the first area 11 and the second area 12 under the guidance of the air guide assembly 30, and the airflow can pass through the plurality of second fins 80 to absorb the heat on the plurality of second fins 80 and take the heat away from the heat dissipation mechanism 100. In this way, heat dissipation of the second electronic mechanism can be achieved through heat conduction of the first housing 50 and the second housing 60 and air cooling of the blowing member 20 .

[0101] The protective cover 70 can be covered on the third area 13, the blowing member 20 and the plurality of air guide components 30, and fixedly connected to the bottom frame 10. The height of the protective cover 70 in the vertical direction can be greater than the height of the first cover shell 50 and the second cover shell 60. The side of the protective cover 70 away from the blowing member 20 in the second horizontal direction can extend in the vertical direction toward the bottom frame 10 and abut against the bottom frame 10; the two sides of the protective cover 70 in the first horizontal direction can extend in the vertical direction toward the bottom frame 10 and abut against the bottom frame 10 or the first cover shell 50 and the second cover shell 60. The protective cover 70 can be provided with a plurality of first air outlets 71 on the side away from the blowing member 20 in the second horizontal direction, wherein some of the first air outlets 71 can be located on the side wall of the protective cover 70 away from the blowing member 20 in the second horizontal direction, and the remaining first air outlets 71 can be provided on the top wall of the protective cover 70 in the vertical direction. The first air outlet 71 can allow the airflow passing through the third area 13 to pass through, so that the airflow that absorbs heat from the radiator 40 is sent out of the heat dissipation mechanism 100. The protective cover 70 is provided with a plurality of second air outlets 72 on both sides in the first horizontal direction, and the plurality of second air outlets 72 are respectively arranged corresponding to the first housing 50 and the second housing 60. The second air outlet 72 can allow the airflow guided by the air guide assembly 30 to pass through, and flow through the plurality of second fins 80 on the first housing 50 and the second housing 60, so as to blow the heat absorbed by the first housing 50 and the second housing 60 away from the heat dissipation mechanism 100.

[0102] It can be understood that the first housing 50 and the second housing 60 can protect the second electronic mechanism while cooperating to achieve air cooling and heat dissipation of the second electronic mechanism. The protective cover 70 can protect the blowing member 20, the air guide assembly 30 and the radiator 40 while providing a channel for the passage of airflow to achieve heat dissipation of the first electronic mechanism and the second electronic mechanism.

[0103] In some embodiments, air guide ports 90 are provided on both the first housing 50 and the second housing 60. The air guide ports 90 can penetrate one or more second fins 80 on the first housing 50 close to the protective cover 70 in the first horizontal direction, and the air guide ports 90 can penetrate one or more second fins 80 on the second housing 60 close to the protective cover 70 in the first horizontal direction. The air guide ports 90 and the second air outlet 72 located on the same side of the heat dissipation mechanism 100 in the first horizontal direction are correspondingly arranged. After the airflow flows out of the protective cover 70 from the second air outlet 72, it can pass through the air guide ports 90 and contact the second fins 80 on the first housing 50 or the second housing 60 where the air guide ports 90 are located, and then continue to flow, thereby taking the heat absorbed by the first housing 50 and the second housing 60 away from the heat dissipation mechanism 100.

[0104] It can be understood that, in the airflow passing through the second air outlet 72, part of the airflow can contact the second fins 80 penetrated by the air guide 90 after passing through the second air outlet 72, and part of the airflow can contact the second fins 80 not penetrated by the air guide 90 after completely passing through the air guide 90. After contacting the second fins 80, the airflow can absorb the heat of the second fins 80, and each second fin 80 can guide the airflow to flow along the interval channel between each adjacent second fin 80, and then flow to the outside of the heat dissipation mechanism 100.

[0105] In this way, the probability of the plurality of second fins 80 being contacted by the airflow can be increased, the air-cooling efficiency of the first housing 50 and the second housing 60 can be improved, and the heat dissipation efficiency of the heat dissipation mechanism 100 can be improved.

[0106] Please also read Fig. 9 In some embodiments, the heat dissipation mechanism 100 may further include a processor 110 and a temperature detection member 120. The processor 110 may be disposed in the receiving space. The number of the temperature detection members 120 may be multiple, and at least one temperature detection member 120 may be disposed corresponding to the first area 11, the second area 12, and the third area 13. Each temperature detection member 120, each first driving member 32, and each second driving member 34 may be communicatively connected to the processor 110. The temperature detection members 120 corresponding to the first area 11, the second area 12, and the third area 13, respectively, may detect the temperatures of the first area 11, the second area 12, and the third area 13, respectively, and output the detection information to the processor 110. The detection information may indicate the temperatures of the first area 11, the second area 12, and the third area 13. The processor 110 can control the operation of the first driving member 32 according to the detection information, so that the air guide member 31 can be directed toward the first area 11, the second area 12 and / or the third area 13, so that the air flow can flow through the first area 11, the second area 12 and / or the third area 13, thereby dissipating the heat to the first area 11, the second area 12 and the third area 13.

[0107] The processor 110 can also be connected to the blowing member 20 for communication. The processor 110 can determine the temperatures of the first area 11, the second area 12, and the third area 13 according to the detection information of the temperature detection member 120, and control the operation and stop of the blowing member 20 according to the determined temperature, and control the working state of the blowing member 20.

[0108] In the embodiment of the present application, there is no specific limitation on the type of the temperature detection element 120. For example, the temperature detection element 120 may be, but is not limited to, a temperature sensor, a thermistor, and the like.

[0109] In the embodiments of the present application, there is no specific limitation on the installation positions of the processors 110 and the temperature detection components 120. For example, the processor 110 can be installed on the first electronic mechanism and located in the receiving space; the temperature detection component 120 corresponding to the third area 13 can be arranged on the third area 13 on the bottom frame 10, or arranged in the receiving space; the temperature detection component 120 corresponding to the first area 11 can be arranged on the first area 11 of the bottom frame 10, or arranged in the first housing 50; the temperature detection component 120 corresponding to the second area 12 can be arranged on the second area 12 of the bottom frame 10, or arranged in the second housing 60.

[0110] It can be understood that the communication connection can be a wired communication connection achieved through a signal line, or it can be a wireless communication connection achieved through 3G, 4G, 5G, wireless LAN, Bluetooth and other technologies, and the embodiments of the present application are not limited to this.

[0111] It can be understood that the working state of the blowing member 20 can correspond to the working power and blowing speed of the blowing member 20. In the embodiment of the present application, the blowing member 20 can work in a first state and a second state. When the blowing member 20 works in the second state, the working power of the blowing member 20 is greater than the working power when the blowing member 20 works in the first state, and the blowing speed of the blowing member 20 is greater than the blowing speed when the blowing member 20 works in the first state. Exemplarily, when the blowing member 20 works in the second state, the working power of the blowing member 20 can be twice the working power when it works in the first state.

[0112] Please also read Figures 10 to 12 , Figures 10 to 12 The directions of airflow guided by the air guide assembly 30 in different situations are shown. The following describes in detail the heat dissipation principle of the heat dissipation mechanism 100 in different situations in combination with the situation that there are two air guide assemblies 30 and the two air guide assemblies 30 are symmetrically arranged:

[0113] In the embodiment of the present application, the processor 110 can continuously detect the temperature of the first area 11, the second area 12 and the third area 13 through each temperature detection element 120 during the operation of the inverter, and the blowing element 20 can be in a stopped state when the inverter starts to work. Fig.10 As shown, at this time, the two air guides 31 are both at an initial angle to face the third area 13 ; the two auxiliary sheets 33 are respectively flush with the corresponding air guides 31 .

[0114] In some cases, when the processor 110 determines that the temperature of the third area 13 reaches the operating threshold through the detection information of the temperature detection member 120, the processor 110 is used to control the blowing member 20 to operate in the first state.

[0115] It is understood that the working threshold value may be a temperature threshold value preset in the processor 110 by a staff member or a manufacturer before the inverter works. In the embodiment of the present application, the value of the working threshold value is not specifically limited. For example, the working threshold value may be any value in [57, 67], and the unit is Celsius. Exemplarily, the working threshold value may be 62 degrees Celsius.

[0116] It can be understood that after the inverter starts working and when the blowing part 20 has not started working, the processor 110 can judge whether the temperature of the third area 13 reaches the working threshold each time it receives the detection information of the temperature detection part 120 corresponding to the third area 13, and after each judgment result is that the working threshold is not reached, it receives the detection information again and judges again.

[0117] After the processor 110 controls the blowing member 20 to work in the first state, the blowing member 20 no longer stops working during the operation of the inverter, and the processor 110 can continue to determine whether the temperature of the point area drops to less than the working threshold through the detection information corresponding to the third area 13.

[0118] In some cases, such as Fig.11 As shown, when the blowing member 20 is working in the first state, when the processor 110 determines that the temperature of the third area 13 drops below the working threshold through the detection information of the temperature detection member 120, the processor 110 is used to control the two second driving members 34 to work. The two second driving members 34 are used to drive the corresponding auxiliary pieces 33 to rotate to form an acute angle with the corresponding air guide plate 311, so that the two auxiliary pieces 33 face the first area 11 and the second area 12 respectively.

[0119] It can be understood that in some scenarios, the heating rate of the first electronic mechanism is greater than the heating rate of the second electronic mechanism, so the temperature of the third area 13 corresponding to the first electronic mechanism will be trapped in the heating of the second area 12 and the third area 13. During the process of the blowing member 20 cooling the third area 13 with air, the temperature of the first area 11 and the second area 12 will rise due to the heating of the second electronic mechanism and the environment in which the inverter is located; after the temperature of the third area 13 drops below the working threshold, the two auxiliary plates 33 can be rotated to form an acute angle with the air guide plate 311, thereby guiding part of the airflow to flow toward the first area 11 and the second area 12, so as to start cooling the first area 11, the second area 12 and the third area 13 simultaneously.

[0120] In some cases, after the two auxiliary plates 33 are respectively oriented toward the first area 11 and the second area 12, when the processor 110 determines through the detection information of the temperature detection component 120 that the temperature of the first area 11 reaches the heat dissipation threshold, the processor 110 is used to control the first driving components 32 in the two air guide components 30 to operate so that the two air guide components 31 rotate to the first angle.

[0121] It is understood that the heat dissipation threshold may be greater than the working threshold, and the heat dissipation threshold may be a temperature threshold preset in the processor 110 by a staff member or a manufacturer before the inverter works. In the embodiment of the present application, the value of the heat dissipation threshold is not specifically limited. For example, the working threshold may be any value in [65, 75], and the unit is Celsius. Exemplarily, the working threshold may be 70 degrees Celsius.

[0122] It can be understood that when the two air guides 31 are at the first angle, the two air guides 31 are both disposed toward the first side of the heat dissipation mechanism 100 , and the air guide 31 located on the first side faces the first area 11 .

[0123] When the temperatures of the first area 11, the second area 12 and the third area 13 are all lower than the heat dissipation threshold, the air guide 31 can maintain its current angle unchanged, thereby maintaining the cooling effect of the airflow blown by the blowing member 20 on various positions of the heat dissipation mechanism 100, so that the temperature of the inverter can be maintained stable.

[0124] When the temperature of the first area 11 is greater than the heat dissipation threshold, the two air guides 31 rotate to the first side toward the heat dissipation mechanism 100, and the direction of the air duct between the two air guides 31 can be adjusted to the first side toward the heat dissipation mechanism 100, thereby increasing the flow rate of the air flow flowing to the first area 11 and improving the heat dissipation efficiency of the heat dissipation mechanism 100 to the first area 11.

[0125] In some cases, when the temperature in the first area 11 is greater than the heat dissipation threshold and the processor 110 controls the two first driving members 32 to operate so that the two air guide members 31 rotate to the first angle, the processor 110 is also used to control the blowing member 20 to switch from the first state to the second state.

[0126] It can be understood that switching the working state of the blowing member 20 to the second state can increase the working power of the blowing member 20, increase the flow rate of the airflow blown out by the blowing member 20, and increase the heat dissipation efficiency of the area where the airflow passes by by increasing the flow rate. In this way, when the temperature of the first area 11 is greater than the heat dissipation temperature, the heat dissipation efficiency of the first area 11 can be improved, and the service life of the inverter can be increased.

[0127] In some cases, when the temperature of the first area 11 is greater than the heat dissipation threshold, and the processor 110 controls the two first driving members 32 to work, so that the two air guides 31 rotate to the first angle, the processor 110 is also used to control the second driving member 34 in the air guide assembly 30 located on the first side to work, so that the corresponding auxiliary piece 33 rotates to be flush with the air guide 31, so as to reduce the dispersion of the air duct, so that more airflow can flow directly to the first area 11. In this way, the heat dissipation efficiency of the first area 11 can be increased.

[0128] It can be understood that, when the air guide member 31 on the second side rotates to the second angle, the auxiliary sheet 33 on the second side rotates synchronously with the air guide member 31 and remains relatively still with the air guide member 31. When the air guide member 31 on the second side faces the first side of the heat dissipation mechanism 100, the auxiliary sheet 33 can face the third area 13 and guide the airflow to flow to the third area 13 to continue to dissipate heat for the third area 13.

[0129] In other cases, the time point when the processor 110 controls the blowing member 20 to operate in the second state may be before or after the processor 110 controls the two first driving members 32 to operate; and the time point when the processor 110 controls the second driving member 34 corresponding to the auxiliary plate 33 located on the first side to operate may be before or after the processor 110 controls the two first driving members 32 to operate, and the embodiments of the present application are not limited to this.

[0130] Similarly, in some cases, after the two auxiliary pieces 33 face the first area 11 and the second area 12 respectively, when the processor 110 determines through the detection information of the temperature detection member 120 that the temperature of the second area 12 reaches the heat dissipation threshold, the processor 110 is used to control the first driving members 32 in the two air guide components 30 to work, so that the two air guide components 31 rotate to the second angle; the processor 110 is also used to control the blowing member 20 to switch to the second state, and is also used to control the second driving member 34 in the air guide component 30 located on the second side to rotate the corresponding auxiliary piece 33 to be flush with the air guide component 31. No further details are given here.

[0131] In other cases, the time point when the processor 110 controls the second driving member 34 corresponding to the auxiliary plate 33 located on the second side to operate may be before or after the processor 110 controls the two first driving members 32 to operate, and the embodiments of the present application are not limited to this.

[0132] In some cases, such as Fig.12As shown, after the two auxiliary pieces 33 are respectively oriented toward the first area 11 and the second area 12, when the processor 110 determines through the detection information of the temperature detection member 120 that the temperatures of the first area 11 and the second area 12 have reached the heat dissipation threshold, the processor 110 is used to control the first driving member 32 in the two air guide components 30 to operate, so that the air guide member 31 located on the first side rotates to the first angle, and the air guide member 31 located on the second side rotates to the second angle.

[0133] When the temperatures of the first area 11 and the second area 12 are both greater than the heat dissipation threshold and the processor 110 controls the two first driving members 32 to work, the processor 110 is also used to control the blowing member 20 to switch to the second state.

[0134] When the temperatures of the first area 11 and the second area 12 are both greater than the heat dissipation threshold and the processor 110 controls the two first driving members 32 to operate, the processor 110 is also used to control the two second driving members 34 to operate, so that the two auxiliary plates 33 are rotated to be flush with the corresponding air guide members 31 to reduce the dispersion of the airflow.

[0135] It can be understood that when the temperature of a single area in the first area 11 and the second area 12 rises to the heat dissipation threshold, the processor 110 can control the two air guides 31 to simultaneously face the side of the heat dissipation mechanism 100 where the temperature rises to the heat dissipation threshold, thereby improving the efficiency of heat dissipation on that side; when the temperatures in both the first area 11 and the second area 12 rise to the heat dissipation threshold, the processor 110 can control the two air guides 31 to face the first area 11 and the second area 12 on the heat dissipation mechanism 100, respectively, to dissipate heat to the first area 11 and the second area 12, respectively, to avoid the temperature rise of one of the first area 11 and the second area 12 being unable to be suppressed, resulting in damage to the inverter.

[0136] At the same time, the processor 110 can control the blowing member 20 to work in the second state, increasing the flow rate of the airflow in the first area 11 and the second area 12; and the processor 110 can control the two auxiliary plates 33 to rotate to be level with the two air guides 31 to reduce the dispersion of the airflow. In this way, the heat dissipation efficiency of the first area 11 and the second area 12 can be increased.

[0137] It can be understood that after completing the control of the first driving member 32, the blowing member 20 and the second driving member 34, the processor 110 can continue to receive the detection information of each temperature detection member 120, so as to determine the temperature changes of the first area 11, the second area 12 and the third area 13.

[0138] In some cases, when the blowing member 20 is working in the second state, when the processor 110 determines that the temperature of the first area 11 and / or the second area 12 drops below the heat dissipation threshold through the detection information of the temperature detection member 120, the processor 110 is used to control the blowing member 20 to work in the first state. In this way, the energy consumption and noise of the inverter can be reduced while keeping the temperature of the first area 11 and / or the second area 12 lowered.

[0139] It can be understood that when the temperature of the first area 11 and / or the second area 12 drops to be lower than that of the heat dissipation area, the angles of the air guide 31 and the auxiliary sheet 33 remain unchanged.

[0140] In some cases, when the blowing member 20 is operating in the first state, when the processor 110 determines through the detection information of the temperature detection member 120 that the temperature of the third area 13 is greater than the operating threshold, the processor 110 is used to control the two first driving members 32 to operate so that the two air guide blades rotate to the initial angle.

[0141] At the same time, the processor 110 is also used to control the two second driving members 34 to work, so that the two auxiliary plates 33 rotate to or maintain being flush with the corresponding air guide members 31 .

[0142] It can be understood that if the processor 110 controls the second driving member 34 to work and the corresponding auxiliary piece 33 is already flush with the air guide member 31 , the second driving member 34 does not work, so that the auxiliary piece 33 is flush with the air guide member 31 .

[0143] It can be understood that after completing the heat dissipation of the first area 11 and / or the second area 12, when the temperature of the third area 13 reaches the working threshold, the air guide assembly 30 can be restored to the initial state, thereby air cooling the third area 13 again.

[0144] After the temperature of the third area 13 drops below the working threshold, the processor 110 can continue to monitor the temperatures of the first area 11, the second area 12 and the third area 13 through each temperature detection component 120, and control the first drive component 32 and the second drive component 34 to operate again when the temperature of the first area 11 and / or the second area 12 reaches the heat dissipation threshold, or the temperature of the third area 13 reaches the working threshold, and control the blowing component 20 to change the working state again, thereby continuously monitoring the temperature and dissipating the heat of each area in the inverter.

[0145] It can be understood that when the number of air guide components 30 is two and the two air guide components 30 are arranged in an array: after the temperature of the third area 13 drops from reaching the working threshold to below the working threshold, the processor 110 can control the air guide 31 located on the second side to rotate to the second angle, and control the corresponding auxiliary sheet 33 to rotate to an acute angle with the air guide plate 311, so that the air guide 31 located on the second side guides the airflow to the second area 12, and the auxiliary sheet 33 located on the second side guides the airflow to the third area 13. And when the temperature of the second area 12 rises to the heat dissipation threshold, the processor 110 can control the auxiliary sheet 33 located on the second side to rotate to fit with the air guide plate 311, so that the air guide 31 and the auxiliary sheet 33 located on the second side are both facing the second area 12. The embodiments of the present application will not be repeated in detail.

[0146] Through the inverter and heat dissipation mechanism 100 provided by the embodiment of the present application, the blowing member 20 can blow airflow toward the third area 13, and the air guide member 31 and the auxiliary sheet 33 in the air guide assembly 30 can rotate to block part of the airflow, and guide the blocked airflow to the first area 11 and the second area 12. In this way, the cooperation between the air guide assembly 30 and the blowing member 20 can achieve heat dissipation in the first area 11, the second area 12 and the third area 13, and reduce the situation where some areas in the inverter cannot receive the airflow blown by the blowing member 20 and cannot dissipate heat, thereby improving the heat dissipation efficiency of the heat dissipation mechanism 100 and the inverter, improving the performance of the inverter, and increasing the service life of the inverter.

[0147] The embodiment of the present application also provides a heat dissipation method, which can be applied to the heat dissipation mechanism 100 provided in the embodiment of the present application. The heat dissipation method can be executed after the inverter starts working, and can be executed by the processor 110. The steps of the heat dissipation method are described in detail below based on the situation that the heat dissipation mechanism 100 includes two symmetrically arranged air guide components 30.

[0148] Please also read Fig.13 and Fig.14 In some embodiments, the heat dissipation method may include steps S1 to S17.

[0149] Step S1: Determine whether the temperature of the third area 13 is greater than or equal to the working threshold.

[0150] The processor 110 can determine whether the temperature of the third area 13 is greater than or equal to the working threshold through the detection information of the temperature detection element 120 corresponding to the third area 13. The specific principle can be found in Figure 2 And the related description will not be repeated here.

[0151] It can be understood that in response to confirming that the temperature of the third area 13 is greater than or equal to the working threshold, the process proceeds to step S2; otherwise, the process returns to step S1.

[0152] Step S2: Determine whether the two air guide assemblies 30 are in an initial state.

[0153] It can be understood that when the air guide assembly 30 is in the initial state, the length direction of the air guide member 31 and the length direction of the auxiliary sheet 33 both coincide with the second horizontal direction, that is, the air guide member 31 and the auxiliary sheet 33 both face the third area 13 .

[0154] In the embodiments of the present application, the manner in which the processor 110 determines the state of the air guide assembly 30 is not specifically limited. For example, the processor 110 may determine whether the air guide assembly 30 is in the initial state based on the work record of controlling the operation of the first drive member 32 and the second drive member 34. For another example, a plurality of angle detection members may be provided in the heat dissipation mechanism 100 to respectively detect the angles of the air guide member 31 and the auxiliary sheet 33, and output the detection results to the processor 110, so that the processor 110 can know whether the air guide assembly 30 is in the initial state.

[0155] It can be understood that in response to confirming that the air guide assembly 30 is not in the initial state, the process proceeds to step S3 and step S4; otherwise, the process proceeds to step S4.

[0156] Step S3: Control the two air guide components 30 to return to the initial state.

[0157] The processor 110 can control the first driving member 32 and the second driving member 34 to work, respectively, to rotate the air guide member 31 and the auxiliary sheet 33, so that the air guide assembly 30 is restored to the initial state. The specific principle can be referred to in Figure 2 And the related description will not be repeated here.

[0158] Step S4: determining whether the blowing member 20 is working in the first state;

[0159] The processor 110 can determine whether the blowing member 20 is working in the first state by detecting parameters such as the working voltage, working current and / or working power of the blowing member 20. When the blowing member 20 is not in the first state, the blowing member 20 may be in a stopped state or working in the second state.

[0160] It can be understood that in response to the blowing member 20 working in the first state, the process proceeds to step S5; otherwise, the process proceeds to step S5 and step S6.

[0161] Step S5: controlling the blowing member 20 to operate in the first state.

[0162] The processor 110 can control the operation and stop of the blowing member 20, and can control the blowing member 20 to operate in different states. The specific principle can be found in Figure 2 And the related description will not be repeated here.

[0163] It can be understood that when the processor 110 determines that the air guide assembly 30 is in the initial state and the blowing piece 20 is not working in the first state, the current scene may be a scene in which the inverter starts working but the blowing piece 20 does not start working; at this time, if the temperature of the third area 13 rises to the operating temperature, the processor 110 can control the blowing piece 20 to start working to start heat dissipation of the inverter.

[0164] When the processor 110 determines that the blowing assembly 30 is not in the initial state, and the blowing member 20 is working in the first state, the current scene may be that the blowing member 20 has been working to dissipate heat for the inverter, and the blowing member 20 has completed the scene of cooling the first area 11 and / or the second area 12 by working in the second state; at this time, if the temperature of the third area 13 rises to the operating temperature, the processor 110 can control the air guide assembly 30 to return to the initial state to dissipate heat for the third area 13 again.

[0165] Step S6: Determine whether the temperature of the third area 13 is less than the working threshold.

[0166] The processor 110 can determine whether the temperature of the third area 13 is less than the working threshold value through the detection information of the temperature detection element 120 corresponding to the third area 13. The specific principle can be referred to in Figure 2 And the related description will not be repeated here.

[0167] It can be understood that in response to confirming that the temperature of the third area 13 is less than the working threshold, step S7 is entered; otherwise, step S6 is returned to determine again whether the temperature of the third area 13 is less than the working threshold.

[0168] Step S7: controlling the two auxiliary plates 33 to rotate to form an acute angle with the air guide plate 311 .

[0169] The processor 110 can control the second driving member 34 to work, thereby controlling the auxiliary plate 33 to rotate. The specific principle can be found in Figure 2 And the related description will not be repeated here.

[0170] Step S8: Determine whether the temperature of the first area 11 is greater than or equal to a heat dissipation threshold.

[0171] The processor 110 can determine whether the temperature of the first area 11 is greater than or equal to the heat dissipation threshold through the detection information of the temperature detection element 120 corresponding to the first area 11. The specific principle can be found in Figure 2 And the related description will not be repeated here.

[0172] It can be understood that in response to the temperature of the first area 11 being greater than or equal to the heat dissipation threshold, the process proceeds to step S9 and step S10 ; otherwise, the process proceeds to step S14 .

[0173] Step S9: Determine whether the temperature of the second area 12 is greater than or equal to a heat dissipation threshold.

[0174] The processor 110 can determine whether the temperature of the second area 12 is greater than or equal to the heat dissipation threshold through the detection information of the temperature detection element 120 corresponding to the second area 12. The specific principle can be found in Figure 2 And the related description will not be repeated here.

[0175] It can be understood that in response to the temperature of the second area 12 being greater than or equal to the heat dissipation threshold, the process proceeds to step S10 and step S11 ; otherwise, the process proceeds to step S12 and step S13 .

[0176] Step S10: Control the air guide member 31 on the first side to rotate to a first angle, control the air guide member 31 on the second side to rotate to a second angle, control the blowing member 20 to work in a second state, and control the two auxiliary plates 33 to rotate to be flush with the corresponding air guide members 31.

[0177] The processor 110 can control the first driving member 32 to work, so that the air guide member 31 rotates; the processor 110 can control the second driving member 34 to work, so that the auxiliary plate 33 rotates. The specific principle can be referred to in Figure 2 And the related description will not be repeated here.

[0178] It can be understood that when the temperatures of the first area 11 and the second area 12 are simultaneously greater than or equal to the heat dissipation threshold, the two air guides 31 can be at the first angle and the second angle, respectively, so as to synchronously guide the airflow to the first area 11 and the second area 12 to synchronously cool the first area 11 and the second area 12.

[0179] Step S11: determining whether the temperatures of the first region 11 and the second region 12 are both lower than a heat dissipation threshold.

[0180] The processor 110 can determine whether the temperatures of the first area 11 and the second area 12 are both less than the heat dissipation threshold through the detection information of the temperature detection element 120 corresponding to the first area 11 and the second area 12. The specific principle can be referred to in Figure 2 And the related description will not be repeated here.

[0181] It can be understood that in response to determining that the temperatures of the first area 11 and the second area 12 are both less than the heat dissipation threshold, step S17 is entered; otherwise, step S11 is returned to determine again whether the temperatures of the first area 11 and the second area 12 are both less than the heat dissipation threshold.

[0182] Step S12: Control the two air guides 31 to rotate to the first angle, control the blowing member 20 to work in the second state, and control the auxiliary piece 33 located on the first side to rotate to be flush with the corresponding air guide 31.

[0183] The processor 110 can control the first driving member 32 to work, so that the air guide member 31 rotates; the processor 110 can control the second driving member 34 to work, so that the auxiliary plate 33 rotates. The specific principle can be referred to in Figure 2 And the related description will not be repeated here.

[0184] It can be understood that when the temperature of the first area 11 is greater than or equal to the heat dissipation threshold at the same time, and the temperature of the second area 12 is less than the heat dissipation threshold, the two air guides 31 can both rotate to the first angle, thereby guiding the airflow to the first side of the heat dissipation mechanism 100, thereby improving the heat dissipation efficiency of the first area 11.

[0185] Step S13: Determine whether the temperature of the first area 11 is less than a heat dissipation threshold.

[0186] The processor 110 can determine whether the temperature of the first area 11 is less than the heat dissipation threshold value through the detection information of the temperature detection element 120 corresponding to the first area 11. The specific principle can be referred to in Figure 2 And the related description will not be repeated here.

[0187] It can be understood that in response to the temperature of the first area 11 being less than the heat dissipation threshold, the process proceeds to step S17 ; otherwise, the process returns to step S13 to determine again whether the temperature of the first area 11 is less than the heat dissipation threshold.

[0188] Step S14: determining whether the temperature of the second area 12 is greater than or equal to a heat dissipation threshold.

[0189] The execution principle of step S14 is the same as or similar to that of step S9, and will not be described in detail here.

[0190] It can be understood that in some cases, in response to the temperature of the second area 12 being greater than or equal to the heat dissipation threshold, step S15 and step S16 are entered. Otherwise, in some cases, step S1 is returned to allow the heat dissipation mechanism 100 to continue to dissipate heat for the inverter; in other cases, step S8 is returned to determine again whether the temperature of the first area 11 is greater than or equal to the heat dissipation threshold; in still other cases, the processor 110 may first determine the working time of the inverter or the specific time of execution according to step S14, and then determine to return to step S1 or step S8 according to a preset rule, wherein the preset rule may record the steps to be returned when the execution result of step S14 under different working times of the inverter is that the temperature of the second area 12 is less than the heat dissipation threshold, and may also record the steps to be returned when the execution result of step S14 is that the temperature of the second area 12 is less than the heat dissipation threshold at different times of each day.

[0191] Step S15 : controlling the two air guides 31 to rotate to a second angle, controlling the blowing member 20 to work in a second state, and controlling the auxiliary piece 33 located on the second side to rotate to be flush with the corresponding air guide 31 .

[0192] The processor 110 can control the first driving member 32 to work, so that the air guide member 31 rotates; the processor 110 can control the second driving member 34 to work, so that the auxiliary plate 33 rotates. The specific principle can be referred to in Figure 2 And the related description will not be repeated here.

[0193] Step S16: Determine whether the temperature of the second area 12 is less than a heat dissipation threshold.

[0194] The processor 110 can determine whether the temperature of the second area 12 is less than the heat dissipation threshold value through the detection information of the temperature detection element 120 corresponding to the second area 12. The specific principle can be referred to in Figure 2 And the related description will not be repeated here.

[0195] It can be understood that in response to the temperature of the second area 12 being less than the heat dissipation threshold, the process proceeds to step S17; otherwise, the process returns to step S16 to determine again whether the temperature of the second area 12 is less than the heat dissipation threshold.

[0196] Step S17: controlling the blowing member 20 to operate in the first state.

[0197] It can be understood that in some cases, the processor 110 may return to step S1 or S8 after executing step S17, so that the heat dissipation mechanism 100 continues to dissipate heat for the inverter. In other cases, the processor 110 may first determine the working time of the inverter or the specific time of execution of step S17, and then determine to return to step S1 or step S8 according to a preset rule, wherein the preset rule may record the steps required to return after step S17 is executed under different working times of the inverter, and may also record the steps required to return after step S17 is executed at different times of each day.
