[0002] With the widespread adoption of energy-saving inverter air conditioning technology, energy-saving window air conditioners generate a significant amount of heat during operation of the inverter electrical box components in cooling mode. Due to the compact internal space and the need to meet waterproofing requirements, this heat accumulates inside the box, causing the components to operate at high temperatures for extended periods. This not only reduces the efficiency of the components but also accelerates their aging and can even lead to malfunctions due to overheating, ultimately affecting the stability and lifespan of the air conditioner. Summary of the Invention

[0003] The main objective of this invention is to provide an electrical box assembly, an air conditioner, and a heat dissipation method to solve the problem of reduced working efficiency and reduced lifespan caused by the inability to dissipate a large amount of heat generated by the electrical control components inside the inverter electrical box assembly in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, an electrical box assembly is provided, comprising:

[0011] Furthermore, the electrical box assembly also includes:

The driving end of each elastic component is set on the outer wall of the corresponding air guide plate, and the fixed end of each elastic component is set on the side wall of the mounting housing. The airflow is moved towards the air guide plate through the heat dissipation component, so that the elastic component deforms under the action of the airflow, causing the air guide plate to rotate and the air outlet to open.

[0024] Furthermore, along the second direction, the height of the ventilation gap is less than the distance between the side of the heating element away from the air inlet and the side wall of the housing away from the air inlet.

[0025] Furthermore, the electrical box assembly also includes:

[0026] The connecting structure is located on the outside of the box. The connecting structure has a connecting inlet and a connecting outlet. The connecting inlet is connected to the air inlet, and the connecting outlet is connected to the outside.

[0027] Furthermore, the electrical box assembly also includes a filter element disposed at the connection inlet; or,

[0028] There are multiple air inlets, arranged in an array; or...

[0029] There are multiple air inlets, and the total area of ​​the multiple air inlets is 15% to 20% of the surface area of ​​the box located on the side with the air inlets; or,

[0030] There are multiple air inlets, which are circular holes with a diameter between 1.9mm and 2.1mm.

[0031] According to another aspect of the present invention, an air conditioner is provided, including an air conditioner housing and an electrical box assembly disposed within the air conditioner housing, wherein the electrical box assembly is the aforementioned electrical box assembly.

[0032] Furthermore, the air conditioner housing includes a chassis structure, which includes a chassis body and a mounting component. The mounting component protrudes from the surface of the chassis body. The chassis body has a chassis air inlet. The mounting component has an installation air inlet and an installation air outlet that are interconnected. The installation air inlet is connected to the chassis air inlet. The air inlet of the electrical box assembly is located at the installation air outlet and is connected to the installation air outlet, so as to mount the electrical box assembly on the chassis structure.

[0033] Furthermore, air conditioners also include:

[0034] The outdoor fan is installed inside the air conditioner casing and located outside the casing.

[0035] The outdoor fan includes an outdoor fan blade and an outdoor motor connected to the outdoor fan blade. The heat dissipation unit of the electrical box assembly is located on the side of the outdoor motor away from the outdoor fan blade; and / or, along the direction perpendicular to the chassis body, the height of the mounting part is between 9.8mm and 10.2mm.

[0036] According to another aspect of the present invention, an air conditioner is provided, comprising an indoor air conditioning unit and an air conditioner, wherein the air conditioner is the air conditioner described above.

[0037] According to another aspect of the present invention, a heat dissipation method is provided, which is applied to the above-described electrical box assembly. The heat dissipation method includes:

[0038] Obtain the real-time average temperature inside the electrical box assembly;

[0039] When the real-time average temperature is higher than the set temperature, the heat dissipation components of the control electrical box assembly are activated to draw the airflow inside the box out to the outside through the air outlet of the box.

[0040] Furthermore, when the real-time average temperature is greater than the set temperature, the heat dissipation components of the control electrical box assembly are activated, including:

[0041] Obtain the temperature-speed mapping table, which includes multiple historical temperature ranges and the historical speeds corresponding to each historical temperature range;

[0042] Based on the real-time average temperature, the mapping table is traversed to determine the corresponding historical rotational speed and marked as the target rotational speed;

[0043] Control the heat sink to operate at the target speed.

[0044] Applying the technical solution of this invention, external cold air enters the interior through the air inlet of the box and flows over the surface of the heating element set inside the box to absorb heat. The heated air accumulates inside the box and flows upward to the air outlet. At this time, the driving component on the mounting base outside the box is activated, driving the heat dissipation component set inside the box and opposite to the air outlet to move. The negative pressure suction force generated by the heat dissipation component forces the hot air accumulated at the air outlet to be discharged to the outside, thereby driving the external cold air to continuously enter from the air inlet, forming a continuous airflow cycle from the air inlet, through the heating element to absorb heat, and through the heat dissipation component to be discharged from the air outlet.

[0045] By placing the drive unit on a mounting base located outside the housing and transmitting power to the heat dissipation component inside the housing via a mechanical connection, spatial separation of the power source and the heat dissipation execution component is achieved. This layout avoids the sealing structure and additional space occupation required for setting up an independent motor inside the housing, which helps maintain the compactness and sealing of the internal structure of the electrical box assembly. At the same time, this structure uses an external drive unit to drive the internal heat dissipation component for forced convection heat dissipation. Compared with the traditional solution that relies on indoor cold air recirculation or additional high-energy-consuming fans, it can more accurately target the heat dissipation inside the electrical box, reduce ineffective energy consumption, meet the requirements of energy-saving air conditioners for reducing system power consumption and improving energy efficiency ratio, and help maintain the heating element at a suitable operating temperature, thereby improving the overall operational stability and reliability of the unit.

[0079] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0080] With the widespread adoption of energy-saving inverter air conditioning technology, energy-saving window air conditioners generate a significant amount of heat during operation of the inverter electrical box components in cooling mode. Due to the compact internal space and the need to meet waterproofing requirements, this heat accumulates inside the box, causing the components to operate at high temperatures for extended periods. This not only reduces the efficiency of the components but also accelerates their aging and can even lead to malfunctions due to overheating, ultimately affecting the stability and lifespan of the air conditioner.

[0081] The main objective of this technical solution is to provide an electrical box assembly, an air conditioner, and a heat dissipation method to solve the problem of reduced working efficiency and reduced lifespan caused by the inability to dissipate a large amount of heat generated by the electrical control components inside the inverter electrical box assembly in existing energy-saving inverter air conditioners.

[0082] First, such as Figures 1 to 21 As shown, this application embodiment provides an electrical box assembly, including:

[0083] The housing 100 and the heating element 200, the housing 100 having an air inlet 101 and an air outlet 102, such as Figure 4 and Figure 5 As shown, the air inlet 101 is located at the bottom of the housing 100, the air outlet 102 is located on the left side wall of the housing 100, and the heating element 200 is located inside the housing 100. Figure 4 As shown, the heating element 200 is disposed on the right side wall of the box 100. There are various types of heating elements 200. For ease of explanation, the elements that need to be dissipated are collectively referred to as heating elements 200.

[0084] The heat dissipation unit 400 includes a driving component 403 and a heat dissipation component 402, such as Figure 16 and Figure 17 As shown, the driving component 403 is driven to connect with the heat sink 402 to drive the heat sink 402 to move. The heat sink 402 is located inside the housing 100 and is positioned opposite to the air outlet 102. The driving component 403 is mounted on the mounting base, which is located outside the housing 100.

[0085] Optionally, the drive component 403 is a drive shaft, and the heat sink 402 is a cooling fan.

[0086] like Figure 4As shown, the heat sink 402 is located at the air outlet 304 and is positioned opposite to the air outlet 102. In this way, when heat dissipation is performed, the hot air inside the box 100 can be drawn out to the outside of the box 100 through the air outlet 102 via the heat sink 402.

[0087] When heat dissipation is required, the drive unit 403 located outside the box 100 is activated and drives the heat dissipation unit 402 connected to it to move. The heat dissipation unit 402 located in the air outlet 304 and opposite to the air outlet 102 creates a negative pressure suction effect inside the box 100, thereby drawing out the hot air accumulated inside the box 100, especially around the heating element 200 near the right side wall. The hot air flows through the air outlet 304 to the air outlet 102, and is finally discharged to the outside of the box 100 through the air outlet 102 located on the left side wall of the box 100, realizing the forced renewal of the air inside the box 100 and the removal of heat.

[0088] By setting a driving component 403 on the outside of the housing 100 and setting a heat sink 402 arranged inside the housing opposite to the air outlet 102, the heat accumulated inside the housing 100 is actively drawn out by the suction force generated by the driving component 403 driving the heat sink 402, avoiding the accumulation of heat inside the housing 100, effectively reducing the operating temperature of the heating element 200, thereby ensuring the stable operation of the electrical box assembly; since this heat dissipation method does not require the consumption of indoor cooling capacity or the introduction of an additional independent high-power fan, it reduces the energy loss caused by heat dissipation, which meets the requirements of energy-saving air conditioners for reducing overall energy consumption and improving energy efficiency ratio.

[0089] Furthermore, such as Figure 3 and Figure 4 As shown, the heat dissipation unit 400 also includes:

[0090] Rotating component 401, at least a portion of which is located within housing 100, has a first end and a second end, the first end being drivenly connected to driving component 403 and the second end being connected to heat sink 402.

[0091] Specifically, in this embodiment, the rotating component 401 is a rotating shaft. The first end of the rotating shaft is driven to the driving component 403, and the second end of the rotating shaft is driven to the heat sink 402, thereby driving the heat sink 402 to rotate.

[0092] Specifically, in this embodiment, the driving component 403 is an electromagnetic clutch.

[0093] When the electrical box assembly needs heat dissipation, the electromagnetic clutch located outside the box 100 acts as a driving component 403, transmitting power to the first end of the rotating component 401. The rotating component 401 drives the heat dissipation component 402 connected to its second end to rotate at high speed in the air outlet 304 inside the box 100. This creates a negative pressure suction effect at the air outlet 102 near the heating element 200 on the right side wall, causing the air inlet 101 at the bottom of the box 100 to draw in external cold air. The cold air flows through the heating element 200 inside the box 100, absorbs heat, and becomes hot air. The hot air flows upward under the negative pressure and is drawn out by the heat dissipation component 402 through the air outlet 304. Finally, it is discharged to the outside of the box 100 through the air outlet 102 located on the left side wall of the box 100, thus achieving forced heat dissipation. The heat dissipation component 402 is a cooling fan.

[0094] By using an electromagnetic clutch as the driving component 403 and utilizing the rotating component 401 to transmit power to the internal heat dissipation component 402, the heat inside the housing 100 is actively extracted without the need for an additional independent motor. This avoids overheating failures of components caused by heat accumulation. Furthermore, since this heat dissipation mechanism only engages when there is a need for heat dissipation and remains disconnected when not dissipating heat, it greatly reduces standby power consumption and operating energy consumption, meeting the stringent requirements of energy-saving air conditioners for reducing overall system energy consumption and improving energy efficiency ratio.

[0095] Furthermore, such as Figure 4 and Figure 5 As shown, the electrical box assembly also includes a controller 404, which is disposed inside the box body 100. Specifically, the controller 404 is disposed on the right side wall of the box body and is connected to the drive unit 403.

[0096] Temperature detection element 500 is connected to controller 404. Temperature detection element 500 is provided on the inner wall surface of housing 100 and / or heating element 200 to detect the real-time average temperature of heating element 200 and / or housing 100, so as to control the opening and closing of drive element 403 and the rotation speed of heat sink 402 according to the real-time average temperature.

[0097] When the temperature sensor 500 is only installed on the inner wall of the box 100, the temperature measured by the temperature sensor 500 is used as the real-time average temperature. When the temperature sensor 500 is installed on the inner wall of the box 100 and on one or more heating elements 200, the average value of the temperature detected by each temperature sensor 500 needs to be calculated and used as the real-time average temperature.

[0098] Specifically, such as Figure 5 As shown, the temperature detection element 500 is disposed on the inner top wall of the housing 100, and the temperature detection element 500 is located above the heating element 200.

[0099] When the temperature sensor 500 detects that the real-time average temperature inside the heating element 200 and / or the housing 100 has reached the set temperature, it transmits a signal to the controller 404. The controller 404 controls the electromagnetic clutch to engage, and the drive component 403 drives the heat sink 402 to rotate inside the housing 100 via the rotating component 401, thereby creating a negative pressure at the air outlet 102. This causes external cold air to enter from the air inlet 101 at the bottom of the housing 100, flow through the heating element 200 to absorb heat and form a hot airflow. The hot airflow is drawn in by the heat sink 402 and discharged through the air outlet 102, thus achieving heat dissipation. When the real-time average temperature drops below the set temperature, the controller 404 controls the electromagnetic clutch to disengage, the heat sink 402 stops rotating, and the heat dissipation process ends.

[0100] By cooperating with the temperature detection element 500, the controller 404 realizes intelligent start-stop control based on real-time temperature. The heat dissipation unit 400 is activated only when the internal temperature of the electrical box assembly is too high, avoiding the energy waste caused by continuous operation or the introduction of indoor cold air in traditional heat dissipation solutions, and effectively reducing the standby power consumption and operating energy consumption of the air conditioning system.

[0101] Furthermore, the electrical box assembly also includes:

[0102] The air guide plate unit 300 is at least partially movable at the air outlet 102 to open or close the air outlet 102.

[0103] Furthermore, such as Figure 5 As shown, the air guide plate unit 300 includes:

[0104] The mounting housing 301 is located at the air outlet 102 and has an air guide window 302 that communicates with the outside.

[0105] Multiple air guide plates 303 are rotatably mounted at the air guide window 302; heat dissipation components 402 are mounted in the air outlet channel 304 formed by the air guide window 302 and the air outlet 102.

[0106] The airflow direction driven by the heat sink 402 is set at a preset angle to the rotation direction of each air guide plate 303, so that the air guide plate 303 rotates under the drive of the heat sink 402. That is, the opening of the air guide plate 303 is achieved by the internal airflow.

[0107] When the heat sink 402 starts to rotate, airflow is formed in the air outlet 304 and flows to the air guide window 302. The airflow acts on the rotatable air guide plate 303, and the airflow push overcomes the reset resistance of the air guide plate 303 to make it rotate and open. At this time, the hot air accumulated inside the box 100 is discharged to the outside through the air guide window 302 and the air outlet 102. When the heat sink 402 stops working, the airflow disappears, and the air guide plate 303 automatically closes the air guide window 302 under the action of the reset mechanism, blocking the air flow inside and outside the box 100.

[0108] By utilizing the airflow generated by the heat sink 402 to drive the air guide plate 303 to open, the air outlet 102 is automatically opened and closed. During heat dissipation, it ensures that the hot airflow is smoothly discharged, and in the non-heat dissipation state, it keeps the air outlet 102 sealed to prevent outdoor dust and rainwater from entering or indoor cool air from escaping. This maintains the thermal balance inside the electrical box components and isolates it from the external environment, reducing the risk of increased energy consumption and component damage caused by heat exchange or pollutant intrusion during non-heat dissipation periods. This is conducive to the long-term stable and efficient operation of energy-saving air conditioners.

[0109] Specifically, such as Figure 19 As shown, each air guide window 302 is provided with an air guide plate shaft. The air guide plate 303 has a rotating hole along the extension direction of the air guide plate shaft. The air guide plate 303 is movably mounted on the air guide plate shaft through the rotating hole, so that it can be opened or closed by airflow. The free end of each air guide plate 303 overlaps with the air guide plate shaft of the adjacent air guide plate 303. That is, under the action of airflow, the air guide plate 303 can only move away from the box 100, and will not deflect into the box 100 under the external airflow.

[0110] Furthermore, such as Figure 14 As shown, the multiple air guide vanes 303 include:

[0111] At least two air guide groups 305 are arranged along the first direction X1, and at least two air guide windows 302 are provided. The at least two air guide groups 305 are provided in a one-to-one correspondence with the at least two air guide windows 302. Each air guide group 305 is provided at its corresponding air guide window 302. Each air guide group 305 includes a plurality of air guide plates 303 arranged along the second direction X2.

[0112] Among them, such as Figure 14 and Figure 15 As shown, one end of the rotating member 401 passes through the mounting housing 301 between two adjacent air guide groups 305 and into the mounting housing 301. The first direction X1 and the second direction X2 are intersected. That is, the mounting housing 301 is provided with a through hole 306 at the position between two adjacent air guide groups 305. The rotating member 401 can extend into the interior of the box 100 through the through hole 306.

[0113] When the heat sink 402 starts to rotate and generate airflow, the airflow flows along the air outlet channel 304 and impacts the air guide plate 303. The airflow exerts a force on the multiple air guide plates 303 that are distributed in an array, overcoming their rotational resistance and causing them to rotate around the air guide plate axis, thereby opening the corresponding air guide window 302. At this time, the hot air accumulated inside the box 100 is drawn out by the airflow and discharged to the outside through the corresponding air guide window 302 and air outlet 102 of each air guide group 305. When the heat sink 402 stops working, the airflow disappears, and the air guide plate 303 rotates and closes under its own gravity, closing the air guide window 302 and blocking the airflow channel.

[0114] By setting up multiple air guide groups 305 and corresponding air guide windows 302 arranged along the first direction X1, and using the rotating component 401 to drive through the through hole 306 in the middle of the adjacent air guide groups, the large-area uniform opening of the air outlet 102 is achieved, ensuring that the hot air inside the box 100 can be efficiently and uniformly extracted, avoiding overheating of components caused by local heat accumulation; at the same time, in the non-heat dissipation state, the structure can seal the air outlet by automatically closing the air guide plate 303, effectively preventing outdoor dust and rainwater from entering or indoor cold air from escaping, reducing energy loss caused by ineffective heat exchange.

[0115] Furthermore, the air guide plate unit 300 also includes:

[0116] Multiple elastic components are provided, each corresponding to a different air guide plate 303. The driving end of each elastic component is located on the outer wall of the corresponding air guide plate 303, and the fixed end of each elastic component is located on the side wall of the mounting housing 301. The airflow is directed towards the air guide plate 303 via the heat sink 402, so that the elastic component deforms under the action of the airflow, causing the air guide plate 303 to rotate and the air outlet 102 to open.

[0117] Specifically, the elastic component is a torsion spring, such as... Figure 15 As shown (the location of the elastic component is not shown), the elastic component is sleeved on one or both ends of the air guide plate shaft. The fixed end of the elastic component is set on the side wall of the mounting housing 301. Specifically, the fixed end of the elastic component is set on the outer edge of the air guide window 302, and the driving end of the elastic component is set on the outer wall surface of each air guide plate 303.

[0118] When the heat sink 402 starts to rotate, the airflow it generates flows to the air guide plate 303 located at the air guide window 302. The airflow impacts the air guide plate 303 and overcomes the restoring torque of the torsion spring, causing the torsion spring to deform and drive the air guide plate 303 to rotate around the axis, thereby opening the air guide window 302. At this time, the hot air accumulated inside the box 100 is discharged to the outside through the opened air guide window 302 and the air outlet 102 under the action of negative pressure. When the heat sink 402 stops working, the airflow disappears, the torsion spring releases the deformation energy to generate a restoring torque, drives the air guide plate 303 to rotate in the opposite direction and return to the closed state, tightly sealing the air guide window 302 and blocking the air circulation inside and outside the box 100.

[0119] By utilizing the torsion spring in conjunction with the air guide plate 303, the air outlet 102 is automatically opened under the drive of the cooling airflow and quickly and automatically closed after the airflow disappears. This ensures that hot air can be efficiently discharged during heat dissipation, and effectively isolates the external environment in the non-heat dissipation state, preventing dust, rainwater intrusion or loss of indoor cool air. It avoids heat exchange loss and energy efficiency reduction caused by the air outlet being constantly open or not tightly closed, meeting the requirements of energy-saving air conditioners for reducing standby power consumption and maintaining efficient system operation.

[0120] Furthermore, such as Figure 4 and Figure 5 As shown, the electrical box assembly also includes:

[0121] A partition member 600 is disposed inside the housing 100. The partition member 600 extends along the second direction X2. The first end of the partition member 600 is connected to the side of the housing 100 near the air inlet 101. A ventilation gap 601 is provided between the second end of the partition member 600 and the side of the housing 100 away from the air outlet 102. A heating element 200 is disposed on the first side of the partition member 600 along its thickness direction. A heat sink 402 and a rotating element 401 are disposed on the second side of the partition member 600 along its thickness direction.

[0122] Specifically, the separating component 600 is a separating plate, and the second direction X2 is in Figure 5 In the vertical direction, the first end of the partition component 600 is connected to the bottom wall of the box body 100, and a ventilation gap 601 is formed between the second end of the partition component 600 and the top wall of the box body 100, allowing ventilation from... Figure 5 As can be seen, the partition 600 divides the interior of the entire box 100 into two chambers, left and right. The left chamber is used to install components such as the heat sink 402, and the right chamber is used to install components such as the heating element 200 and the controller 404. The air inlet 101 is located in the right chamber, thus forming a heat dissipation flow path. After the air enters from the air inlet 101, it flows through the heating element 200 and enters the ventilation gap 601, and then enters the air outlet 102 along the partition 600.

[0123] External cold air enters through the air inlet 101 located at the bottom of the right chamber, flows over the surface of the heating element 200 located on the first side of the partition 600 to absorb heat, and the heated air flows upward and enters the left chamber through the ventilation gap 601 formed between the second end of the partition 600 and the top wall of the box 100. It is then drawn in by the heat sink 402 located in the left chamber and finally discharged to the outside of the box 100 through the air outlet 102 located on the left side wall, forming a directional heat dissipation flow path from the right chamber, through the heating element 200 to the ventilation gap 601, and out of the left chamber.

[0124] By setting a partition 600, the interior of the housing 100 is divided into a right chamber for installing the heating element 200 and a left chamber for installing the heat sink 402, and the two chambers are connected by a ventilation gap 601, thus creating a clear directional heat dissipation flow path. This ensures that cold air flows directly through the heating element 200 for efficient heat exchange, avoiding short circuits or mixing of hot and cold airflows, thereby improving heat dissipation efficiency. At the same time, this partition structure helps to isolate the heat-generating area from the electrical drive area, reducing the impact of heat on sensitive electronic components such as the controller 404, and ensuring the stability and reliability of the electrical box assembly under long-term operation of the energy-saving air conditioner.

[0125] Furthermore, along the second direction X2, the height of the ventilation gap 601 is less than the distance between the side of the heating element 200 away from the air inlet 101 and the side wall of the housing 100 away from the air inlet 101.

[0126] Specifically, such as Figure 5 As shown, the height of the partition component 600 is greater than the total height of the right side wall of the housing 100 occupied by all the heating elements 200.

[0127] By setting a partition component 600 with a height greater than that of the heating element 200, the airflow is forced to pass through the surface of the heating element 200 to reach the ventilation gap 601. This effectively prevents cold air that has not participated in heat exchange from being directly short-circuited and discharged, ensuring that the cold air entering the housing 100 can fully absorb the heat generated by the heating element 200, significantly improving heat dissipation efficiency. At the same time, this directional flow path design reduces ineffective heat exchange losses, which is conducive to maximizing the overall cooling energy efficiency ratio of the energy-saving air conditioner while maintaining the low-temperature stable operation of the electrical box components.

[0128] Furthermore, such as Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the electrical box assembly also includes:

[0129] The connecting structure 700 is located outside the housing 100. The connecting structure 700 has a connecting inlet 701 and a connecting outlet 702. The connecting inlet 701 is connected to the air inlet 101, and the connecting outlet 702 is connected to the outside.

[0130] Specifically, the connecting structure 700 includes a first portion 704 and a second portion 705, such as Figure 11 As shown, the first portion 704 is a rectangular structure, and the second portion 705 is located below the first portion 704. The second portion 705 is a rectangular frame structure that extends outwards to connect with the chassis structure 800, thereby increasing the connection strength between the connecting structure 700 and the chassis structure 800. Figure 11 From the inside, the side of the connecting structure 700 is L-shaped.

[0131] External cold air enters through the connecting outlet 702 on the outside of the connecting structure 700, flows along the inside of the rectangular frame structure of the second section, then enters the first section, and finally flows into the air inlet 101 inside the box 100 through the connecting inlet 701, and then flows into the right chamber and through the heating element 200, completing the air intake process from the outside through the connecting structure 700 to the inside of the electrical box.

[0132] By setting an L-shaped connection structure 700 that includes a second section (an outwardly folded rectangular frame structure), the connection between the second section and the chassis structure 800 increases the strength and stability of the overall structure, effectively preventing loosening or deformation at the connection due to vibration or external force, ensuring the airtightness of the air intake channel, avoiding a decrease in heat dissipation efficiency or an increase in energy consumption due to air leakage, and helping energy-saving air conditioners maintain long-term stable operating performance and structural reliability.

[0133] Furthermore, such as Figure 13 As shown, the electrical box assembly also includes a filter element 703 disposed at the connection inlet 701. The filter element 703 is a metal mesh.

[0134] By setting a metal mesh as a filter element 703 at the connection inlet 701, external foreign objects are effectively blocked from entering the electrical box assembly, preventing foreign objects from accumulating on the surface of the heating element 200 or obstructing the airflow channel, thereby avoiding local overheating and reduced heat dissipation efficiency caused by blockage of the heat dissipation channel; this helps to maintain the long-term stable heat dissipation performance of the electrical box assembly, reduce the additional energy consumption caused by increased cleaning and maintenance needs, and meet the requirements of energy-saving air conditioners for low maintenance costs and efficient operation.

[0135] Furthermore, such as Figure 13 As shown, there are multiple air inlets 101, and the multiple air inlets 101 are arranged in an array.

[0136] By setting multiple air inlets 101 arranged in an array, the air inlet cross-sectional area is increased and the uniformity of airflow distribution in the right chamber is optimized, ensuring that each heat-generating element 200 can obtain sufficient cooling airflow and avoiding airflow short-circuiting or uneven local heat dissipation caused by single-point air inlet. This uniform air inlet design improves the overall heat dissipation efficiency, which helps energy-saving air conditioners maintain the low temperature operation of components while reducing energy loss caused by local overheating, and improving the stability and reliability of the system.

[0137] Furthermore, there are multiple air inlets 101, and the total area of ​​the multiple air inlets 101 is 15% to 20% of the surface area of ​​the box 100 located on the side of the air inlet 101, that is, the total area of ​​the multiple air inlets 101 is 15% to 20% of the total area of ​​the bottom wall of the box 100.

[0138] By limiting the total area of ​​multiple air inlets 101 to 15%~20% of the total area of ​​the bottom wall of the box 100, the opening ratio of the air inlets is optimized while ensuring sufficient air intake to maintain effective heat dissipation. This avoids airflow short-circuiting or structural strength weakening caused by excessive air intake area, and also prevents excessive wind resistance and insufficient heat dissipation caused by insufficient air intake area. This ensures that the energy-saving air conditioner maintains the structural stability of the electrical box components and the stability of airflow while achieving efficient heat dissipation, thereby improving the overall energy efficiency performance of the unit.

[0139] Furthermore, there are multiple air inlets 101, each of which is a circular hole with a diameter between 1.9 mm and 2.1 mm.

[0140] This application embodiment also provides an air conditioner, which includes an air conditioner housing and an electrical box assembly disposed within the air conditioner housing, wherein the electrical box assembly is the aforementioned electrical box assembly.

[0141] The air conditioner in this technical solution is mainly for window air conditioners, which are located on the indoor side and the outdoor side. The electrical box assembly in this technical solution is mainly located on the outdoor side of the window air conditioner.

[0142] By integrating the aforementioned electrical box components with zoned heat dissipation, gravity self-closing, and intelligent start-stop control, this air conditioner effectively avoids short-circuiting of airflow that does not participate in heat exchange while utilizing the outdoor fan's power for forced heat dissipation, ensuring targeted and efficient heat dissipation. This structure, while ensuring stable low-temperature operation of the electrical box components, significantly improves the overall refrigeration efficiency ratio and operational reliability of the energy-saving air conditioner by providing on-demand heat dissipation and reducing ineffective energy consumption.

[0143] Furthermore, such as Figure 13 and Figure 14As shown, the air conditioner housing includes a chassis structure 800, which includes a chassis body 801 and a mounting member 802. The mounting member 802 protrudes from the surface of the chassis body 801. The chassis body 801 has a chassis air inlet 803. The mounting member 802 has an interconnected mounting air inlet and mounting air outlet, which are connected to the chassis air inlet 803. The air inlet 101 of the electrical box assembly is located at and connected to the mounting air outlet, allowing the electrical box assembly to be mounted on the chassis structure 800. Specifically, the connecting structure 700 of the electrical box assembly is connected to the mounting member 802. Figure 13 As shown, the second part 705 of the connecting structure 700 covers the outside of the mounting member 802 and is connected to the outer wall of the mounting member 802. The height of the mounting member 802 is between 9.8mm and 10.2mm along the direction perpendicular to the chassis body 801. Specifically, the height of the mounting member 802 is 10mm.

[0144] External cold air first enters through the chassis air inlet 803 on the chassis body 801, and then flows into the mounting part 802 connected to the chassis air inlet 803. The airflow passes through the mounting air inlet and the mounting air outlet in sequence, and finally enters the electrical box assembly air inlet 101 set in the second part 705 of the connecting structure 700 through the mounting air outlet. Then it enters the box 100 and flows through the heating element 200 for heat exchange, completing the airflow introduction process from the chassis structure 800 to the electrical box assembly.

[0145] By setting a mounting part 802 that protrudes from the surface of the chassis body 801 and has a height of 9.8mm~10.2mm (preferably 10mm), and using it as an airflow transition connection structure, efficient connection between the chassis air inlet 803 and the electrical box assembly air inlet 101 is achieved. This ensures both the smoothness and airtightness of the air intake path, and optimizes the matching space between the connection structure 700 and the mounting part 802 through specific height dimensions, thereby enhancing the assembly stability of the overall structure. This is beneficial for energy-saving air conditioners to maintain the long-term reliable heat dissipation performance of the electrical box assembly while reducing airflow resistance.

[0146] Furthermore, air conditioners also include:

[0147] The outdoor fan 900 is installed inside the air conditioner casing and located outside the box 100;

[0148] The outdoor fan 900 includes an outdoor fan blade 901 and an outdoor motor 902 connected to the outdoor fan blade 901. The heat dissipation unit 400 of the electrical box assembly is located on the side of the outdoor motor 902 away from the outdoor fan blade 901.

[0149] The outdoor motor 902 drives the outdoor fan blade 901 to rotate at high speed, generating a strong airflow suction force inside the air conditioner casing. This airflow mainly flows through the condenser for heat exchange, and part of the airflow is guided to the heat dissipation unit 400 of the electrical box assembly, which is located on the side of the outdoor motor 902 away from the outdoor fan blade 901, under the action of the negative pressure zone formed on the leeward side of the outdoor motor 902. When the airflow flows through the heat dissipation component 402 in the heat dissipation unit 400, it carries away the heat inside the electrical box and is finally discharged through the air outlet 102 of the electrical box assembly, forming a forced convection heat dissipation path dominated by the outdoor fan 900.

[0150] By placing the heat dissipation unit 400 of the electrical box assembly on the side of the outdoor motor 902 away from the outdoor fan blade 901, effective heat dissipation of the electrical box assembly can be achieved without the need for an additional independent cooling fan, significantly reducing system energy consumption. At the same time, this layout enables efficient reuse of the power source, reduces the number of mechanical parts and failure points, and helps energy-saving air conditioners improve heat dissipation efficiency while reducing overall power consumption and improving the overall reliability of the system.

[0151] This application also provides an air conditioner, including an indoor unit and an air conditioner, which is the air conditioner described above.

[0152] By applying air conditioners with efficient zoned heat dissipation and intelligent control functions to air conditioners, this air conditioner ensures efficient indoor cooling while utilizing outdoor fan power reuse technology to achieve low-power heat dissipation of electrical box components, avoiding additional energy consumption and loss of indoor cooling capacity. This overall configuration effectively improves the overall cooling efficiency ratio of energy-saving air conditioners, extends the service life of electrical components, and enhances the operational stability of the system under complex operating conditions.

[0153] This application embodiment also provides a heat dissipation method, which is applied to the above-mentioned electrical box assembly. The heat dissipation method includes:

[0154] Obtain the real-time average temperature inside the housing 100 of the electrical box assembly;

[0155] When the real-time average temperature is greater than the set temperature, the heat sink 402 of the control electrical box assembly is activated to draw the airflow inside the box 100 out to the outside through the air outlet 102 of the box 100.

[0156] Furthermore, when the real-time average temperature is greater than the set temperature, the heat sink 402 of the control electrical box assembly is activated, including:

[0157] Obtain the temperature-speed mapping table, which includes multiple historical temperature ranges and the historical speeds corresponding to each historical temperature range;

[0158] Based on the real-time average temperature, the mapping table is traversed to determine the corresponding historical rotational speed and marked as the target rotational speed;

[0159] Control the heat sink 402 to operate at the target speed.

[0160] The system collects the average temperature inside the electrical box assembly housing 100 in real time. When the monitored real-time average temperature exceeds the set temperature, the control unit retrieves the preset temperature-speed mapping table. By traversing the table, it searches for the historical speed range that matches the current real-time temperature to determine the corresponding target speed. Then, it controls the heat sink 402 to start running at the target speed. The negative pressure airflow generated by the heat sink 402 forces the hot air accumulated inside the housing 100 to be discharged to the outside through the air outlet 102. At the same time, it causes the external cold air to enter the housing 100 from the air inlet 101, thereby forming a directional airflow circulation path.

[0161] By introducing a speed mapping control strategy based on real-time temperature, this heat dissipation method achieves precise matching between the speed of the heat sink 402 and the heat generation of the electrical box components. This avoids overcooling or insufficient heat dissipation caused by traditional constant-speed heat dissipation, ensuring effective heat dissipation under high-temperature conditions and significantly reducing the energy consumption of the heat dissipation components under low-temperature conditions. This on-demand, variable-speed heat dissipation mechanism meets the requirements of energy-saving air conditioners for low-power operation, improving the overall energy efficiency of the unit while maintaining the stable operating temperature of electrical components.
