[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] It should be noted that this application is based on the inventor's understanding and research into the following issues:

[0033] Figure 1 The thermal management system in the related art is shown, such as Figure 1 As shown, the main control board 101, drive board 102, filter components 103, and reactor 104 are all housed in a single enclosure. This means that both temperature-sensitive and non-temperature-sensitive components are within the same enclosure. Therefore, the thermal fields of different components can interfere with each other, leading to a decrease in the reliability of the control box. Furthermore, as... Figure 2 As shown, the drive board 102, filter device 103 and reactor 104 are all placed on the same side of the heat dissipation device 50. Therefore, the heat dissipation device 50 has a large area, which increases the cost of the heat dissipation device 50, thereby increasing the cost of the electrical control box.

[0034] Based on this, embodiments of the present invention provide an electrical control box, an outdoor unit, and an air conditioner. By placing the components on both sides of the heat dissipation device, the components on both sides can share the same heat dissipation device, effectively reducing the area of ​​the heat dissipation device and thus reducing the cost of the electrical control box.

[0035] The electrical control box, outdoor unit, and air conditioner of this utility model are described below with reference to the accompanying drawings.

[0036] Figure 3 This is a structural schematic diagram of an electrical control box according to an embodiment of the present invention. Figure 3 As shown, the electrical control box includes: a first housing 10, a second housing 20, a first type of device 30, a second type of device (41 and 42) and a heat dissipation device 50.

[0037] The first housing 10 has a first receiving cavity; the second housing 20 has a second receiving cavity; a first type of device 30 is disposed in the first receiving cavity, and a second type of device (41 and 42) is disposed in the second receiving cavity, wherein the heat generated by the first type of device 30 is less than the heat generated by the second type of device 40; a heat dissipation device 50 is disposed in the second receiving cavity and includes a first surface and a second surface opposite to each other, wherein a portion of the second type of device 41 is disposed on the first surface, and the remaining second type of device 42 is disposed on the second surface.

[0038] Specifically, the first housing 10 and the second housing 20 form two cavities inside the electrical control box, namely the first receiving cavity and the second receiving cavity. The heat generated by the first type of device 30 is less than that of the second type of device (41 and 42), so the thermal fields of the first type of device 30 and the second type of device (41 and 42) are different. The first type of device 30, which generates less heat, is placed in the first receiving cavity, and the second type of device (41 and 42), which generates more heat, is placed in the second receiving cavity. In this way, the thermal fields of the first type of device 30 and the second type of device (41 and 42) will not interfere with each other. Furthermore, because the first type of device 30 generates less heat, it does not need to be equipped with a heat dissipation device 50 in the first receiving cavity. However, the second type of device 40 generates more heat, so it needs a heat dissipation device 50. Therefore, a heat dissipation device 50 (e.g., refrigerant pipe heat dissipation) is placed in the second receiving cavity. Some of the second-type devices 41 and the remaining second-type devices 42 are placed on both sides of the heat dissipation device 50. The heat dissipation device 50 can dissipate heat from the second-type devices (41 and 42) on both sides at the same time. This can effectively reduce the heat dissipation area required by the second-type devices (41 and 42), thereby reducing the heat dissipation area of ​​the heat dissipation device 50.

[0039] It should be noted that the first type of device 30 and the second type of device (41 and 42) are selected according to the application scenario of the control box. When the control box is applied in the outdoor unit of the air conditioner, the first type of device 30 and the second type of device (41 and 42) can be components used to drive and control the compressor and the outdoor fan.

[0040] In an alternative implementation, where the control box is used in the outdoor unit of an air conditioner, the first type of device 30 includes... Figure 1 The main control board 101 shown is primarily used for communication with indoor units, as well as for dry contact wiring and human-machine interaction for special functions. This means that it needs to be opened for operation when the equipment is installed on-site. The main control board 101 has low overall heat generation. The second type of device 40 includes, for example... Figure 2 The drive board 102, filter device 103, and reactor 104 shown are examples of devices that generate a lot of heat.

[0041] In the above embodiments, two accommodating cavities are formed inside the control box, and devices with different heat outputs are placed in different accommodating cavities according to their heat output, thereby solving the problem of thermal field interference between different devices and improving the reliability of the control box. Furthermore, the second type of device is set on both sides of the heat dissipation device, and the second type of device on both sides can share the same heat dissipation device, which can effectively reduce the area of ​​the heat dissipation device and thus reduce the cost of the control box.

[0042] In some embodiments, some of the second-type devices 41 are more sensitive to temperature than the remaining second-type devices 42.

[0043] Specifically, the second type of devices (41 and 42) includes devices with different temperature sensitivities. Based on the temperature sensitivity of the devices, the second type of devices (41 and 42) are placed on both sides of the heat dissipation device 50. In this way, the second type of devices on the same side of the heat dissipation device 50 will not interfere with each other, thereby further improving the reliability of the electrical control box.

[0044] Exemplary, in some embodiments, such as Figure 4 As shown, part of the second type of device 41 includes a drive board 102 adapted to drive at least one of a compressor and a fan, and the remaining second type of device 42 includes at least one of a filter device 103 and a reactor 104.

[0045] When the control box is used in an air conditioner, the second type of devices (41 and 42) may include a drive board 102, a filter device 103 (e.g., an inductor, capacitor, etc.), and a reactor 104. The filter device 103 and the reactor 104 generate significant heat and are not easily affected by temperature, while the drive board 102 is a temperature-sensitive device and is greatly affected by temperature. Therefore, the filter device 103 and the reactor 104 are placed on the second surface of the heat dissipation device 50, and the drive board 102 is placed on the first surface of the heat dissipation device 50, so that the two types of devices will not interfere with each other.

[0046] In some embodiments, such as Figure 5 As shown, some of the second type of devices 41 include a first component 411 and a second component 412. The distance between the first component 411 and the second component 412 meets a preset distance. The temperature sensitivity of the second component 412 is less than that of the first component 411.

[0047] Specifically, both the first component 411 and the second component 412 are placed on the first surface of the heat sink 50. Therefore, components with different temperature sensitivities can be placed on the same side of the heat sink 50. However, a preset distance needs to be maintained between the first component 411 and the second component 412 to prevent the thermal fields of the two types of components from interfering with each other. It should be noted that the preset distance needs to be determined based on the thermal field of the components.

[0048] In some embodiments, the temperature sensitivity of the remaining second type of device 42 is less than that of the first component 411.

[0049] In other words, the remaining second-type devices 42 can also be devices with low temperature sensitivity. Therefore, some devices with low temperature sensitivity are placed on the first surface, and the remaining devices with low temperature sensitivity are placed on the second surface.

[0050] In some embodiments, the first component 411 includes a drive board 102 adapted to drive at least one of a compressor and a fan, the second component 412 includes one of a filter component 103 and a reactor 104, and the remaining second type of component 42 includes the other of a filter component 103 and a reactor 104.

[0051] For example, such as Figure 6 As shown, a drive plate 102 and a filter component 103 are disposed on the first surface of the heat dissipation device 50, and a reactor 104 is disposed on the second surface of the heat dissipation device 50; or, as shown Figure 7 As shown, a drive plate 102 and a reactor 104 are provided on the first surface of the heat dissipation device 50, and a filter device 103 is provided on the second surface of the heat dissipation device 50.

[0052] In some embodiments, such as Figure 8 As shown, the second receiving cavity also includes a first sub-receiving cavity and a second sub-receiving cavity, wherein the first component 411 is disposed in the first sub-receiving cavity and the second component 412 is disposed in the second sub-receiving cavity.

[0053] Specifically, the second receiving cavity also includes two sub-receiving cavities, such as... Figure 6 As shown, the two sub-cavities can be formed by the partition 21, a portion of the second housing 20, and the first surface. The first component 411 is disposed in the first sub-cavity, and the second component 412 is disposed in the second sub-cavity, so that components with different temperature sensitivities are disposed in different sub-cavities.

[0054] In the above embodiment, the second receiving cavity includes two sub-receiving cavities, and the first component and the second component can be placed in different sub-receiving cavities, thereby further avoiding mutual interference of the thermal fields of the two types of components.

[0055] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, the driver board 102 includes a circuit board 1201 and a power module 1202 disposed on the circuit board 1201. The power module 1202 includes a third surface and a fourth surface opposite to each other. The third surface is disposed on the circuit board 1201 and the fourth surface is disposed on the first surface.

[0056] Specifically, the driver board 102 includes a circuit board 1201 and a power module 1202. The power module 1202 includes a third surface and a fourth surface. The third surface is disposed on the circuit board 1201, and the fourth surface is disposed on the first surface. Therefore, the power module 1202 is disposed close to the heat dissipation device 50 so that the heat dissipation device 50 can better dissipate heat from the power module 1202.

[0057] Optionally, the power module 1202 includes at least one of a compressor power module and a fan power module.

[0058] In the above embodiments, because the power module generates a lot of heat, it is placed close to the heat dissipation device to further reduce the operating temperature of the power module, thereby further improving the reliability of the control box.

[0059] In summary, the electrical control box according to this embodiment includes a first housing, a second housing, a first type of device, a second type of device, and a heat dissipation device. The first housing has a first receiving cavity, and the second housing has a second receiving cavity. The first type of device is disposed in the first receiving cavity, and the second type of device is disposed in the second receiving cavity. The heat generation of the first type of device is less than that of the second type of device. The heat dissipation device is disposed in the second receiving cavity and includes opposing first and second surfaces. A portion of the second type of device is disposed on the first surface, and the remaining second type of device is disposed on the second surface. Thus, two receiving cavities are formed within the electrical control box, and devices with different heat generation are placed in different receiving cavities according to their heat generation, thereby solving the problem of thermal interference between different devices and improving the reliability of the electrical control box. Furthermore, the second type of device is disposed on both sides of the heat dissipation device, allowing the second type of device on both sides to share the same heat dissipation device, effectively reducing the area of ​​the heat dissipation device and thus reducing the cost of the electrical control box.

[0060] Corresponding to the above embodiments, this utility model also proposes an outdoor unit. For example... Figure 9 As shown, the outdoor unit 200 includes: a compressor 201, a fan 202, and an electrical control box 100 of any of the aforementioned embodiments, wherein the electrical control box 100 is connected to the compressor 201 and the fan 202 respectively, and the electrical control box 100 is configured to control the compressor 201 and the fan 202 respectively.

[0061] According to the outdoor unit of this utility model embodiment, by adopting the above-mentioned electrical control box, the components are placed on both sides of the heat dissipation device, so that the components on both sides share the same heat dissipation device, effectively reducing the area of ​​the heat dissipation device, thereby reducing the cost of the electrical control box.
