[0002] Air conditioners are now widely used in people's daily lives, allowing them to cool or heat indoors to regulate the temperature. However, with the development of society and improvements in living standards, people's demands for a higher quality of life are also increasing. For example, air conditioners now also include main control boards such as IPMs (Intelligent Power Modules) to integrate multiple functions into a single module, thereby achieving more precise and efficient motor control, which is crucial for variable-frequency air conditioners. However, during use, these main control boards generate heat and remain in a high-temperature state. If they remain in this high-temperature state for a long time, their lifespan will be shortened.

If the temperature of the main control board is high, the fan can be turned on to circulate air in the housing through the heat dissipation holes, thereby achieving the effect of cooling the main control board.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] In the related art, the existing air conditioner is provided with a fan and heat dissipation holes, which can only remove the heat dissipated by the main control board through air flow, and the heat dissipation effect is poor. The main control board may still be in a high temperature state for a long time.

[0033] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure.

For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in certain circumstances. For those of ordinary skill in the art, the specific meanings of these terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0036] Furthermore, the terms "disposed," "connected," and "fixed" should be interpreted broadly.

[0037] Unless otherwise stated, the term "plurality" means two or more.

[0038] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0039] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0041] In the prior art, a main control computer board, such as an IPM (Intelligent Power Module), is installed inside an air conditioner to integrate multiple functions into a single module. When the air conditioner is operating at high temperatures, the computer board generates a large amount of heat, so a fan is typically installed inside the air conditioner to cool the computer board.

[0042] However, for the above-mentioned air conditioner equipped with a fan, when the outdoor temperature continues to rise, the air cooling mode has a poor cooling effect on the computer board, resulting in the compressor being unable to continue to increase the frequency, thereby affecting the cooling effect of the air conditioner.

[0043] like Figures 1 to 4 As shown, the disclosed embodiments provide an outdoor unit 03 for an air conditioner and an air conditioner. When the temperature of the heat dissipation element of the main control board of the air conditioner is high, the water-cooling liquid in the water cooling tank 20 can be used to dissipate heat from the heat dissipation device 10, thereby improving the heat dissipation effect of the heat dissipation device 10 on the heat dissipation element 01. This arrangement can improve the heat dissipation efficiency of the heat dissipation element 01, thereby preventing the heat dissipation element 01 from being in a high temperature state.

[0044] like Figures 1 to 4As shown, the disclosed embodiment provides an outdoor unit 03 for an air conditioner, comprising: a housing, a heat sink 10, and a water-cooling tank 20. The housing is provided with a mounting cavity, in which a heat dissipation element 01 is disposed; the heat sink 10 is disposed in the mounting cavity for dissipating heat from the heat dissipation element 01; and the water-cooling tank 20 is disposed in a position corresponding to the mounting cavity and the heat sink 10. The water-cooling tank 20 is used to store cooling liquid, and the heat dissipation element 01 is at least partially immersed in the cooling liquid.

[0045] Specifically, the heat dissipation component 01 of the outdoor unit 03 is a computer board installed in the casing. The heat dissipation device 10 includes a heat dissipation portion 11 attached to the computer board and fins 12 in contact with the heat dissipation portion 11. The heat dissipation portion 11 is used to dissipate heat from the computer board, and the fins 12 are used to dissipate heat from the heat dissipation portion 11. The upper end of the water cooling box 20 is provided with an opening, and the size of the opening is greater than or equal to the size of the heat dissipation device 10. The user can inject water-cooling liquid into the water cooling box 20 through the opening, and then install the water cooling box 20 in the installation cavity of the casing. At this time, the fins 12 of the heat dissipation device 10 are partially or completely immersed in the water-cooling liquid, and the water-cooling liquid can dissipate heat from the fins 12, thereby improving the heat dissipation effect of the heat dissipation device 10 on the heat dissipation component 01. Such a setting can improve the heat dissipation efficiency of the heat dissipation component 01, thereby preventing the heat dissipation component 01 from being in a high temperature state.

[0046] In practical applications, at least 1 / 3 of the heat dissipation device 10 is immersed in the water-cooling liquid to ensure the heat dissipation effect of the water-cooling liquid on the heat dissipation device 10 .

[0047] Optionally, heat element 01 is located above water-cooling box 20, and the distance between heat element 01 and water-cooling box 20 is greater than or equal to 0.5 cm. For example, the distance between heat element 01 and water-cooling box 20 can be 0.5 cm, 1 cm, or 1.5 cm. This arrangement prevents the coolant in water-cooling box 20 from splashing onto heat element 01.

[0048] Optionally, a waterproof member is provided at a position corresponding to the heat dissipation component 01 and the water cooling box 20 to further prevent the water-cooling liquid in the water cooling box 20 from splashing onto the heat dissipation component 01.

[0049] Optionally, the water cooling box 20 is detachably mounted in the mounting cavity. In this way, the user can take the water cooling box 20 out of the mounting cavity, and then inject or replace the water cooling liquid in the water cooling box 20, which is more convenient for the user to operate.

[0050] like Figure 4As shown, in some embodiments, the air conditioner further includes an indoor unit 02, and the indoor unit 02 includes: a condensed water tank 04; a water cooling box 20 is provided with a water inlet 21 and a water outlet 22; wherein the water inlet 21 and the water outlet 22 are respectively connected to the condensed water tank 04 through pipelines, and the condensed water in the condensed water tank 04 can flow into the water cooling box 20 through the pipeline to form a water-cooled liquid.

[0051] Specifically, the water inlet 21 and the water outlet 22 of the water cooling box 20 are provided with waterproof rings to prevent the water-cooling liquid from dripping from the water inlet 21 and the water outlet 22 to other components of the outdoor unit 03.

[0052] When the heat dissipation element 01 is at a high temperature, the condensed water in the condensed water tank 04 can flow into the water cooling tank 20 through the water inlet 21 of the water cooling tank 20 via a pipe. The condensed water flowing into the water cooling tank 20 forms a water-cooled liquid, which dissipates heat from the heat dissipation device 10. After the water-cooled liquid absorbs heat from the heat dissipation device 10, it can flow out of the water cooling tank 20 through the water outlet 22 and flow back into the condensed water tank through the pipe, completing the condensed water circulation. This configuration ensures that the water-cooled liquid in the water cooling tank 20 remains at a low temperature, thereby ensuring the heat dissipation effect of the heat dissipation device 10.

[0053] It is understandable that, generally speaking, the temperature of condensed water is relatively low, and dissipating the heat from the heat dissipation device 10 through the condensed water in the condensed water tank 04 can not only save water resources but also ensure the heat dissipation effect of the heat dissipation device 10 .

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, the water inlet 21 is disposed at the lower half of the water cooling box 20 , and the water outlet 22 is disposed at the upper half of the water cooling box 20 .

[0055] Specifically, when the temperature of the heat dissipation element is high, the condensed water in the condensed water tank 04 can flow through the pipe from the lower half of the water cooling box 20. As the water level in the water cooling box 20 rises, the condensed water gradually soaks the heat dissipation device 10. When the water level in the water cooling box 20 rises to the water outlet 22, the condensed water can flow out of the water cooling box 20 from the water outlet 22, forming a fluid water flow.

[0056] It is understandable that setting the water inlet 21 of the water cooling box 20 in the lower half of the water cooling box 20 can reduce the height of the coolant flowing into the water cooling box 20, thereby preventing the coolant from dripping directly onto the bottom wall of the water cooling box 20.

[0057] like Figure 2As shown, in some embodiments, the outdoor unit 03 for the air conditioner further includes a water level sensor 31 and an alarm device 33. The water level sensor 31 is disposed in the water cooling tank 20 and is used to obtain the water level in the water cooling tank 20. The alarm device 33 is electrically connected to the water level sensor 31. When the water level in the water cooling tank 20 is higher than or equal to a first water level, the water level sensor 31 can trigger the alarm device 33.

[0058] Specifically, the height of the first water level is higher than the height of the water outlet 22 of the water cooling tank 20. A warning device 33 is provided on the housing to provide a user with a prompt. When the water level in the water cooling tank 20 is higher than or equal to the first water level, the water level sensor 31 sends a high water level signal to the warning device 33, triggering the warning device 33. At this point, the warning device 33 emits an audible or visual signal to remind the user that the water cooling tank 20 is at a high water level. With this configuration, the outdoor unit 03 can promptly remind the user to pour out or pump out the condensed water in the water cooling tank 20 to prevent the coolant from overflowing from the opening of the water cooling tank 20.

[0059] In the above embodiment, the first water level can be set according to the actual needs of the user, and the main requirement is that the height of the first water level is higher than the height of the water outlet 22 of the water cooling box 20. The height of the first water level refers to the height between the surface of the water-cooling liquid and the bottom wall of the water cooling box 20, and the height of the water outlet 22 refers to the height from the water outlet 22 to the bottom wall of the water cooling box 20.

[0060] In practical applications, the warning device 33 may be a device with a warning function such as a sound prompt or a light prompt.

[0061] like Figure 2 As shown, in some embodiments, the outdoor unit 03 for the air conditioner further includes a valve element. The valve element is disposed at the water inlet 21 and is used to clear or block the water inlet 21. The valve element is electrically connected to a water level sensor 31. When the water level in the water cooling tank 20 is higher than or equal to a first water level, the water level sensor 31 can control the valve element to block the water inlet 21.

[0062] Specifically, the valve body element is a solenoid valve, which is arranged at the water inlet 21. When the heat dissipation element 01 is in a high temperature state, the valve body element opens to clear the water inlet 21. At this time, the condensed water in the condensed water tank 04 can flow through the pipeline from the lower half of the water cooling box 20. As the water level in the water cooling box 20 rises, the condensed water gradually soaks the heat dissipation device 10. When the water level in the water cooling box 20 is higher than or equal to the first water level, the water level sensor 31 determines that the water cooling box 20 is in a high water level state and sends a high water level signal to the valve body element. After the valve body element receives the high water level signal, the valve body element closes and blocks the water inlet 21 to prevent the condensed water in the condensed water tank 04 from continuing to flow into the water cooling box 20, thereby preventing the condensed water in the water cooling box 20 from overflowing.

[0063] like Figure 2 As shown, in some embodiments, the outdoor unit 03 for the air conditioner further includes a temperature sensor 32. The temperature sensor 32 is disposed in the water cooling tank 20 and is used to obtain the water temperature in the water cooling tank 20. The temperature sensor 32 is electrically connected to the valve element and can control the opening of the valve element according to the water temperature in the water cooling tank 20.

[0064] Specifically, when the water-cooling liquid in the water-cooling box 20 absorbs the heat of the heat dissipation device 10, the temperature of the water-cooling liquid itself will also rise, thereby affecting the heat dissipation effect on the heat dissipation device 10. When the temperature sensor 32 detects that the water temperature in the water-cooling box 20 is less than or equal to the first preset temperature, it is determined that the water-cooling box 20 is in a low-temperature state, and a low-temperature signal is sent to the valve body element. After the valve body element receives the low-temperature signal, the valve body element can reduce the opening until it is closed to reduce the flow of condensed water, thereby saving water resources. When the temperature sensor 32 detects that the water level in the water-cooling box 20 is greater than or equal to the second preset temperature, it is determined that the water-cooling box 20 is in a high-temperature state, and a high-temperature signal is sent to the valve body element. After the valve body element receives the high-temperature signal, the valve body element can increase the opening until it is fully opened to increase the flow of condensed water, thereby improving the heat dissipation effect on the heat dissipation device 10.

[0065] like Figure 1 As shown, in some embodiments, the outdoor unit 03 for the air conditioner further includes a water receiving tray 40. The water receiving tray 40 is arranged below the water cooling box 20 and is used to receive the water-cooled liquid overflowed from the water cooling box 20.

[0066] Specifically, the water receiving pan 40 is fixedly mounted and located below the water cooling box 20. This allows the pan 40 to collect leaked or overflowed coolant from the water cooling box 20, or condensed water from the water cooling box 20 itself. This prevents coolant or condensed water from dripping onto other components of the outdoor unit 03, thereby extending the service life of the outdoor unit 03.

[0067] Optionally, the projection of the water cooling box 20 on the horizontal plane where the water receiving pan 40 is located completely falls into the water receiving pan 40 to ensure that the water-cooling liquid or condensed water completely falls into the water receiving pan 40.

[0068] In some embodiments, the water receiving tray 40 is connected to the condensed water tank 04 through a pipeline, and the water in the water receiving tray 40 can flow into the condensed water tank 04 through the pipeline.

[0069] Specifically, when the water-cooling liquid or condensed water drips onto the water receiving pan 40 , it can flow into the condensed water tank 04 through the pipeline to prevent the water in the water receiving pan 40 from overflowing.

[0070] In some embodiments, the outdoor unit 03 for the air conditioner further includes a filter. The filter is arranged at the water inlet 21 of the water cooling box 20.

[0071] Specifically, the filter is detachably installed at the water inlet 21 to filter the condensed water flowing into the water cooling box 20 to improve the water quality of the condensed water flowing into the water cooling box 20, thereby avoiding the occurrence of scale or other impurities in the water cooling box 20.

[0072] If the filter is clogged by scale or other impurities, the user can remove the filter from the water inlet 21 to clean or replace the filter.

[0073] like Figures 1 to 4 As shown, the embodiment of the present disclosure further provides an air conditioner comprising: a computer board and the outdoor unit 03 for the air conditioner. The computer board is arranged in the mounting cavity of the housing, and the computer board constitutes the heat dissipation element 01; wherein the heat dissipation device 10 is used to dissipate heat from the computer board.

[0074] Specifically, the heat dissipation device 10 can dissipate heat from the computer board, and the water-cooling liquid in the water-cooling box 20 can dissipate heat from the heat dissipation device 10, thereby improving the heat dissipation efficiency of the heat dissipation device 10 on the computer board.

[0075] Such an arrangement can improve the heat dissipation efficiency of the heat dissipation element 01 , thereby preventing the heat dissipation element 01 from being in a high temperature state.
