[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] The disclosure below provides many different embodiments or examples to realize the different structures of the embodiments of the present application. In order to simplify the disclosure of the embodiments of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present application. In addition, the embodiments of the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0039] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0040] In order to solve the problems in the prior art, the present application provides a heat dissipation mechanism, an air conditioner and a temperature control method for an electrical box. The heat dissipation mechanism can realize zoned heat dissipation and temperature control according to different areas in the controller, thereby avoiding failure of devices with high heat generation due to untimely heat dissipation.

[0041] like Figure 1-8 As shown, the embodiment of the present application provides a heat dissipation mechanism for dissipating heat from an air conditioner electrical box 5, and the air conditioner electrical box 5 is provided with at least two partitions 51; the heat dissipation mechanism includes: a substrate 1, at least two groups of heat dissipation components 2, and a cold source component 3. Specifically, the air conditioner electrical box 5 is provided with multiple modules, such as a fan module, a compressor module, etc., and different modules have different heat generation under different working conditions. The partitions 51 in the electrical box 5 are set according to the distribution positions of different modules.

[0042] At least two groups of heat dissipation components 2 are arranged on the substrate 1, and at least two groups of heat dissipation components 2 respectively have a heat absorption end 21 and a heat dissipation end 22, and the heat absorption end 21 of the heat dissipation component 2 dissipates heat to the partition 51 of the air conditioner electrical box 5. Specifically, each heat dissipation component 2 corresponds to a partition 51 of the air conditioner electrical box 5, and the temperature control of the partitions 51 in different areas of the electrical box 5 can be realized.

[0043] The cold source component 3 exchanges heat with the heat dissipation ends 22 of at least two groups of heat dissipation components 2; when the heat of a partition 51 in at least two partitions 51 exceeds a threshold, the heat dissipation component 2 is controlled to perform additional cooling on the partition 51.

[0044] In the present application, the heat of the electrical box 5 is absorbed by the heat absorbing end 21 of the heat dissipation component 2, and the heat is taken away by the cold source component 3 to achieve heat dissipation and cooling of the electrical box 5. By setting independent heat dissipation components 2 to correspond to different partitions 51 of the electrical box 5, heat dissipation and temperature control of the partitions 51 can be achieved according to different areas in the electrical box 5. When the heat in the partition 51 exceeds the threshold, the heat dissipation component 2 is controlled to perform additional cooling on the partition 51, thereby avoiding malfunctions of devices with high heat in the electrical box 5 due to untimely heat dissipation.

[0045] In the related art, the existing air conditioner electrical box 5 usually dissipates heat as a whole, that is, a unified module heat dissipation is adopted for the entire electrical box 5. However, since there are many different components in the electrical box 5, the heat generated by each component when working and under different working conditions is different, and the heat generation of each component is unstable. The high frequency or long working time of some components will also increase the heat generation. Therefore, the use of a unified heat dissipation method will inevitably cause some components with higher heat to be unable to be effectively dissipated and cooled, thereby affecting the performance of the component and affecting the service life of the entire air conditioner electrical box 5.

[0046] In the embodiment of the present application, the electrical box 5 is divided into partitions 51, and then the multiple partitions 51 are cooled respectively by multiple heat dissipation components 2, thereby realizing temperature control and heat dissipation of the partitions 51 of the devices in the multiple electrical boxes 5. Even if the heat generation is unstable and the devices increase the heat due to the high working frequency, that is, when the temperature in the partition 51 exceeds the threshold, the corresponding heat dissipation component 2 can be controlled to perform additional cooling on the partition 51, thereby ensuring that the temperature of the partition 51 is reduced to below the threshold, thereby ensuring that each device in the electrical box 5 is within the proper temperature range, ensuring the performance of the device and the service life of the electrical box 5.

[0047] In some embodiments, the heat dissipation component 2 includes a plurality of heat pipes 23 , each of which has a heat absorbing end 21 and a heat dissipation end 22 that can exchange heat with the heat absorbing end 21 , and the cold source component 3 is a refrigerant pipe 31 of an air conditioner.

[0048] In the present application, the multiple heat pipes 23 of the heat dissipation assembly 2 are used together to dissipate heat for the partition 51 of the electrical box 5. The heat generated by the components in the partition 51 of the electrical box 5 is exchanged with the heat absorbing end 21 of the heat pipe 23 to transfer the heat to the heat pipe 23, and then the heat dissipation end 22 of the heat pipe 23 is exchanged with the refrigerant pipe 31 of the air conditioner to dissipate the heat, thereby achieving heat dissipation and cooling of the partition 51 in the electrical box 5. The refrigerant pipe 31 of the air conditioner has a relatively low temperature, and the heat dissipation effect of the partition 51 of the electrical box 5 can also be ensured, especially when the outdoor temperature is high.

[0049] Specifically, the interior of the heat pipe 23 is filled with a coolant, and the coolant is in a two-phase form. The coolant is in a liquid state at the heat absorbing end 21, and becomes a gas after absorbing heat and flows to the heat dissipating end 22, thereby carrying the heat to the heat dissipating end 22. After the heat dissipating end 22 dissipates heat, it becomes a liquid state and returns to the heat absorbing end 21 again. Heat conduction through the two-phase coolant has a better heat conduction effect than direct heat conduction through a conductor, and a certain temperature difference can be made between the heat dissipating end 22 and the heat absorbing end 21 of the heat pipe 23. The temperature of the heat absorbing end 21 is higher than that of the heat dissipating end 22, and components can also be protected.

[0050] like Figure 3 As shown, in some embodiments, the heat pipe 23 has a control valve 231 for controlling on and off. When the control valve 231 is in an open state, the heat absorption end 21 of the heat pipe 23 exchanges heat with the heat dissipation end 22. When the control valve 231 is in a closed state, the heat absorption end 21 of the heat pipe 23 stops exchanging heat with the heat dissipation end 22.

[0051] In the present application, the on and off of the heat pipe 23 can be controlled by the control valve 231, so as to adjust the number of the heat pipes 23 in the working state in the heat dissipation component 2. When it is necessary to additionally cool the devices in the partition 51, more heat pipes 23 are opened to increase the number of working heat pipes 23, thereby achieving additional cooling of the partition 51; when the temperature of the devices in the partition 51 decreases, a certain number of heat pipes 23 can be appropriately closed to ensure the cooling capacity of the refrigerant pipe 31.

[0052] like Figure 3 As shown, in some embodiments, the heat pipe 23 has a regulating valve 232 , and the regulating valve 232 is used to adjust the heat exchange efficiency of the heat pipe 23 .

[0053] In the present application, the heat exchange efficiency of the heat pipe 23 can be adjusted by the regulating valve 232, specifically, as follows: Figure 4 As shown, the regulating valve 232 can be a control valve 231, and the control valve 231 is arranged between the heat absorbing end 21 and the heat dissipating end 22. When the control valve 231 is in a fully open state, the flow space between the heat absorbing end 21 and the heat dissipating end 22 is opened to the maximum, and the heat exchange efficiency of the heat pipe 23 is the highest. When the control valve 231 is partially opened, the flow space between the heat absorbing end 21 and the heat dissipating end 22 is reduced, so that the heat exchange efficiency of the heat pipe 23 becomes smaller. The smaller the opening angle of the control valve 231, the smaller the heat exchange efficiency of the heat pipe 23. When the control valve 231 is completely closed, the heat absorbing end 21 and the heat dissipating end 22 are completely separated, and the heat pipe 23 is in a non-working state.

[0054] like Figure 5-6 As shown, in some embodiments, the heat dissipation mechanism further includes an adjustment component 4 disposed on the substrate 1 , and the adjustment component 4 is used to adjust at least part of the heat pipe 23 of the heat dissipation component 2 to move between at least two partitions 51 .

[0055] In the present application, the regulating component 4 drives at least part of the heat pipes 23 of the heat dissipation component 2 to move from one partition 51 to another partition 51, so as to increase the number of heat pipes 23 in one partition 51, thereby improving the heat dissipation effect of the partition 51. The temperature control of different partitions 51 in the electrical box 5 can be handled by simply increasing or decreasing the number of heat pipes 23 in one partition 51; the movement of the heat pipe 23 and the on and off of the heat pipe 23 can also be coordinated to achieve the temperature control of different partitions 51 in the electrical box 5.

[0056] In some embodiments, a guide structure 11 is provided on the substrate 1 along the arrangement direction of at least two partitions 51, and the adjustment component includes a sliding module 41 and a power module 42. The output end of the power module 42 is connected to the sliding module 41 to drive the sliding module 41 to slide along the guide structure 11. The sliding module 41 is connected to the heat pipe 23.

[0057] In the present application, the guide structure 11 can be a guide groove or a guide rail, the power module 42 is a motor 421 arranged on the substrate 1 and a gear 422 arranged at the power end of the motor 421, and the sliding module 41 is a rack 411, the rack 411 slides along the guide groove or the guide rail, and the rack 411 is also engaged with the gear 422. The gear 422 rotates to drive the rack 411 to slide along the guide structure 11, and the rack 411 drives the heat pipe 23 to move, thereby realizing the movement of the heat pipe 23 between different partitions 51.

[0058] like Figure 6 As shown, specifically, a fixed groove 12 and a movable groove 13 are provided on the substrate 1, and the heat pipe 23 includes a fixed heat pipe 23 and a movable heat pipe 23. The fixed heat pipe 23 is provided in the fixed groove 12 and its position remains unchanged. The movable heat pipe 23 is provided in the movable groove 13 and connected to the rack 411, and the heat pipe 23 can be driven to move along the movable groove 13 by the rack 411. In a specific embodiment, the heat pipe 23 includes three fixed heat pipes 23 and two movable heat pipes 23 in total, and the two movable heat pipes 23 are respectively arranged at intervals from the three fixed heat pipes 23. When the two movable heat pipes 23 move upward, the number of heat pipes 23 in the upper partition 51 increases, and when the two movable heat pipes 23 move downward, the number of heat pipes 23 in the lower partition 51 increases.

[0059] Optionally, the power module 42 can also be a motor 421 and a screw rod arranged at the power end of the motor 421. The sliding module 41 is a slider that cooperates with the screw rod thread. The slider slides along the guide structure 11 and is connected to the mobile heat pipe 23, thereby driving the mobile heat pipe 23 to move between the two partitions 51.

[0060] It should be noted that the adjustment component 4 in the present application is not limited to the method provided above, and any driving method that can drive the heat pipe 23 to move between the two partitions 51 is acceptable.

[0061] In some embodiments, the partition 51 of the air conditioner electrical box 5 includes a first partition 511 and a second partition 512, the cold source component 3 includes a first refrigerant tube 311 and a second refrigerant tube 312, the temperature of the refrigerant in the first refrigerant tube 311 is lower than the temperature of the refrigerant in the second refrigerant tube 312; the heat dissipation component 2 includes a first heat dissipation component 2 for dissipating heat to the first partition 511 and a second heat dissipation component 2 for dissipating heat to the second partition 512, the first heat dissipation component 2 includes a first heat pipe 233, the second heat dissipation component 2 includes a second heat pipe 234, the heat dissipation end 22 of the first heat pipe 233 exchanges heat with the first refrigerant tube 311, and the heat dissipation end 22 of the second heat pipe 234 exchanges heat with the second refrigerant tube 312.

[0062] Because the components that generate heat in the electrical box 5 are mainly the fan module and the compressor module, the heat generated by the compressor module is greater than that of the fan module. The heat generated by the fan module is relatively stable, while the heat generated by the compressor fluctuates greatly due to the influence of the starting frequency. Therefore, the area corresponding to the compressor module is the first partition 511, and the area corresponding to the fan module is the second partition 512.

[0063] like Figure 7 As shown, in the present application, the air-conditioning electrical box 5 has two partitions 51, namely a first partition 511 and a second partition 512. The first heat dissipation component 2 is used to dissipate heat and cool the components in the first partition 511 of the electrical box 5, and the second heat dissipation component 2 is used to dissipate heat and cool the components in the second partition 512 of the electrical box 5. The first refrigerant pipe 311 and the second refrigerant pipe 312 select different positions of the air-conditioning refrigerant pipe 31, so that the temperature of the refrigerant in the first refrigerant pipe 311 is lower than the temperature of the refrigerant in the second refrigerant pipe 312. The first heat pipe 233 exchanges heat with the first refrigerant pipe 311, and the second heat pipe 234 exchanges heat with the second refrigerant pipe 312, so that the heat exchange efficiency of the first heat pipe 233 is higher than the heat exchange efficiency of the second heat pipe 234, thereby realizing temperature control of the partitions 51 of the first partition 511 and the second partition 512 of the electrical box 5, increasing the heat dissipation effect of the first partition 511 with higher heat, and thereby ensuring that the components in the first partition 511 and the second partition 512 are within a suitable temperature range.

[0064] The embodiment of the present application does not control the temperature of the partition 51 of the electrical box 5 by increasing or decreasing the number of operable heat pipes 23, but realizes the temperature control of the partition 51 by heat exchange between the heat pipes 23 corresponding to different partitions 51 and the refrigerant pipes 31 of different temperatures, and the partition 51 with higher heat corresponds to the refrigerant pipe 31 with lower temperature. Of course, this embodiment can also be combined with the above-mentioned increase or decrease in the number of operable heat pipes 23 to jointly complete the temperature control of the partition 51 of the electrical box 5.

[0065] like Figure 8 As shown, in some embodiments, the first heat dissipation component 2 further includes a third heat pipe 235 , and the heat dissipation end 22 of the third heat pipe 235 exchanges heat with the second refrigerant pipe 312 .

[0066] In the present application, the first heat dissipation component 2 dissipates heat to the first partition 511 through the first heat pipe 233 and the third heat pipe 235. When the temperature of the first partition 511 is low, the first partition 511 can be dissipated only through the third heat pipe 235. When the temperature of the first partition 511 increases, the third heat pipe 235 can be turned off to dissipate heat to the first partition 511 through the first heat pipe 233. When the temperature of the first partition 511 increases again, the first heat pipe 233 and the third heat pipe 235 can be turned on at the same time to dissipate heat to the first partition 511.

[0067] In some embodiments, the heat absorption end 21 of the heat dissipation component 2 and the partition 51 of the air-conditioning electrical box 5 exchange heat through the substrate 1 .

[0068] In the present application, the components in the electrical box 5 are kept in contact with the substrate 1, and the heat dissipation component 2 is arranged on the substrate 1, and can also exchange heat with the substrate 1. By using the substrate 1 as a heat transfer medium between the electrical box 5 and the heat dissipation component 2, the contact area can be effectively increased, and when the heat pipe 23 of the heat dissipation component 2 moves, the effective heat dissipation of the electrical box 5 can also be ensured. Furthermore, the heat dissipation component 2 dissipates the components in the electrical box 5 through the substrate 1, and the heat dissipation component 2 does not directly dissipate the components of the electrical box 5, which can also prevent the heat absorption end 21 of the heat dissipation component 2 from being too low, causing condensation to form at the electrical box 5 and affecting the normal operation of the components in the electrical box 5.

[0069] The heat dissipation mechanism absorbs the heat of the electrical box 5 through the heat absorption end 21 of the heat dissipation component 2, and takes the heat away through the cold source component 3 to achieve heat dissipation and cooling of the electrical box 5. By setting independent heat dissipation components 2 to correspond to different partitions 51 of the electrical box 5, heat dissipation and temperature control of the partitions 51 can be achieved according to different areas in the electrical box 5. When the heat in the partition 51 exceeds the threshold, the heat dissipation component 2 is controlled to perform additional cooling on the partition 51, thereby avoiding malfunction of components with high heat in the electrical box 5 due to untimely heat dissipation.

[0070] An embodiment of the present application provides an air conditioner, comprising the above-mentioned heat dissipation mechanism.

[0071] Specifically, an air-conditioning electrical box 5 is provided in the outer unit of the air conditioner, and the heat dissipation mechanism mainly dissipates heat for the electrical box 5 in the outer unit. Because the electrical box 5 is in the external environment, it is greatly affected by the outdoor temperature. In addition, the heat generated by the components in the electrical box 5 itself can easily cause the temperature in the electrical box 5 to overheat. By adopting the heat dissipation mechanism of the present application, different areas in the electrical box 5 can be zoned 51 for control, so that different components in the electrical box 5 can work within a suitable temperature range, thereby avoiding the components in the electrical box 5 from affecting the heat dissipation effect due to different or unstable heat generation.

[0072] like Fig. 9 As shown, the embodiment of the present application provides a temperature control method for an air conditioner electrical box, which is applied to the above-mentioned air conditioner. The temperature control method includes:

[0073] S1, obtaining heat from at least two partitions 51 of the air-conditioning electrical box 5, the partitions 51 dissipate heat from the air-conditioning electrical box 5 through the heat-absorbing end 21 of the heat-dissipating component 2, and the heat-dissipating end 22 of the heat-dissipating component 2 exchanges heat through the cold source component 3;

[0074] S2. When the heat of a partition 51 among at least two partitions 51 exceeds a threshold, control the heat dissipation component 2 corresponding to the partition 51 to perform additional cooling on the partition 51.

[0075] In the present application, the temperature of the electrical box 5 can be controlled by partition 51 through the heat dissipation component 2. By obtaining the heat of each partition 51, the heat can be directly detected, or it can be reflected indirectly according to the working conditions of the devices in the partition 51. If the device works with high power, long duration, and high frequency, the heat generated is large, and if the device works with low power, short duration, and low frequency, the heat generated is small. When the heat in the partition 51 exceeds the threshold, the heat dissipation component 2 is controlled to perform additional cooling on the partition 51.

[0076] In some embodiments, the heat dissipation component 2 includes multiple heat pipes 23, and controlling the heat dissipation component 2 corresponding to the partition 51 for additional cooling includes: increasing the number of heat pipes 23 in working state by opening the control valve to turn on the non-working heat pipes, or increasing the number of heat pipes 23 in working state in the partition 51 by moving the heat pipes 23 from other partitions 51 to the partition 51.

[0077] In the present application, increasing the number of working heat pipes 23 includes: adjusting the heat pipes 23 that were originally in a non-working state to a working state, moving the heat pipes 23 of other partitions 51 to the partition 51, or moving the idle heat pipes 23 to the partition 51, which can increase the number of working heat pipes 23 in the partition 51, thereby coping with the situation where the heat of the partition 51 exceeds the threshold.

[0078] In other embodiments, the heat dissipation component 2 includes a plurality of heat pipes 23 , and controlling the heat dissipation component 2 corresponding to the partition 51 to perform additional cooling includes: improving the heat exchange efficiency of the heat pipes 23 .

[0079] In the present application, the heat exchange efficiency of the heat pipe 23 can be improved by increasing the flow rate of the coolant in the heat pipe 23. The heat pipe 23 is filled with coolant, and the coolant is in a two-phase state. The coolant is liquid at the heat absorption end 21, and becomes gaseous after absorbing heat and flows to the heat dissipation end 22, thereby carrying heat to the heat dissipation end 22. After heat dissipation at the heat dissipation end 22, it becomes liquid and returns to the heat absorption end 21 again. The heat exchange efficiency of the heat pipe 23 is controlled by adjusting the channel size between the heat absorption end 21 and the heat dissipation end 22.

[0080] In another embodiment, the electrical box 5 includes a first partition 511 and a second partition 512, the heat dissipation component 2 includes a first heat dissipation component 2 and a second heat dissipation component 2, the first heat dissipation component 2 dissipates heat for the first partition 511, and the second heat dissipation component 2 dissipates heat for the second partition 512, the refrigerant pipe 31 includes a first refrigerant pipe 311 and a second refrigerant pipe 312, the temperature of the refrigerant in the first refrigerant pipe 311 is lower than the temperature of the refrigerant in the second refrigerant pipe 312, the first heat dissipation component 2 includes a first heat pipe 233 for heat exchange with the first refrigerant pipe 311, the second heat dissipation component 2 includes a second heat pipe 234 for heat exchange with the second refrigerant pipe 312, the first heat pipe 233 and the second heat pipe 234 have different heat exchange efficiencies, thereby realizing the temperature control of the first partition 511 and the second partition 512 of the electrical box 5. When the heat of the first partition 511 or the second partition 512 exceeds the threshold, the flow rate of the coolant in the first heat pipe 233 or the second heat pipe 234 is increased.

[0081] Furthermore, the first heat dissipation component 2 also includes a third heat pipe 235 for exchanging heat with the second refrigerant pipe 312. The first heat pipe 233 and the third heat pipe 235 jointly dissipate heat for the first partition 511. When the temperature of the first partition 511 is low, heat can be dissipated only by the third heat pipe 235. As the temperature of the first partition 511 increases, the first heat pipe 233 can be turned on to dissipate heat, or the flow rate of the coolant in the first heat pipe 233 or the third heat pipe 235 can be increased to improve heat dissipation.
