[0025] The following further details the present disclosure in conjunction with the drawings and embodiments. It should be understood that the embodiments provided herein are only used to explain the present disclosure and not to limit the present disclosure. Additionally, the embodiments provided below are partial embodiments for implementing the present disclosure, rather than all embodiments for implementing the present disclosure.

However, the heat dissipation control method of the air conditioner provided by the embodiments of the present disclosure is not limited to the recorded steps. Similarly, the heat dissipation control device of the air conditioner provided by the embodiments of the present disclosure includes a series of units.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this disclosure belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.
[0029] It can be understood that in the specific implementation of this application, when it comes to relevant data, when the embodiments of this application are applied to specific products or technologies, user permission or consent is required, and the collection, use, and processing of relevant data need to comply with the relevant laws, regulations, and standards of relevant countries and regions.
[0030] Figure 1 The structural diagram of an air conditioner according to an embodiment of the present application is schematically shown. Figure 2 The flowchart of the heat dissipation control method of an air conditioner according to an embodiment of the present application is schematically shown.
[0031] The execution subject of the heat dissipation control method of the air conditioner can be any heat dissipation control device of an air conditioner with processing capabilities. The heat dissipation control device of the air conditioner can be set in devices such as an air conditioner, a mobile phone, a computer, a smart watch, and other household electrical appliances. The heat dissipation control device of the air conditioner can at least include a memory and a processor.
[0032] As Figure 1 shown, the air conditioner may include an outdoor unit 110. The outdoor unit 110 may include a heat pipe radiator 111, a subcooler 112, and an electronic control module 114 of a compressor 113. The electronic control module 114 is disposed on the heat pipe radiator 111, and the refrigerant pipeline 1121 of the subcooler 112 passes through the condensation end 1111 of the heat pipe radiator 111.
[0033] On this basis, as Figure 2 shown, the heat dissipation control method of the air conditioner may include steps S210 to S230.
[0034] Step S210, if it is monitored that the actual temperature of the module of the electronic control module is greater than or equal to the first temperature limit value, calculate the expansion valve opening according to the actual temperature of the module and the first temperature limit value;
[0035] Step S220: Open the subcooler electronic expansion valve on the refrigerant pipeline to the expansion valve opening degree, so that the refrigerant flows through the condensation end via the refrigerant pipeline to assist the heat pipe radiator in dissipating heat from the electronic control module.
[0036] Step S230: If it is monitored that the actual module temperature of the electronic control module is less than the second temperature limit value, close the subcooler electronic expansion valve, where the second temperature limit value is less than or equal to the first temperature limit value.
[0037] The heat pipe radiator 111 can utilize the property of absorbing and dissipating heat during the phase change process for cooling and heat dissipation. Refer to Figure 3 and Figure 4 , the heat pipe radiator 111 may specifically include a heat pipe 1113, a heat dissipation substrate 1114, and heat dissipation fins 1115. The heat pipe is disposed on the heat dissipation substrate 1114, the heat dissipation fins 1115 are disposed below the heat dissipation substrate 1114, and the electronic control module 114 may be disposed on the heat dissipation substrate 1114.
[0038] The refrigerant pipeline 1121 of the subcooler 112 passes through the condensation end 1111 of the heat pipe radiator 111. When the electronic control module 114 generates heat, a section of the pipe on the evaporation end 1112 side of the heat pipe 1113 starts to be heated, and the liquid around the pipe wall of this section of the pipe will instantly vaporize to generate vapor. At this time, the pressure of this section of the pipe will increase, causing the vapor flow to flow under the traction of the pressure to a section of the pipe on the condensation end 1111 side of the heat pipe 1113. After the vapor flow reaches the section of the pipe on the condensation end 1111 side, it condenses into a liquid, and at the same time, heat is also released through the heat dissipation substrate 1114 and the heat dissipation fins 1115, thereby dissipating heat from the electronic control module 114.
[0039] Among them, the refrigerant pipeline passes through the condensation end 1111 of the heat pipe radiator 111, and it can be that the refrigerant pipeline passes through from above, inside, or below the condensation end 1111. Passing through inside means that the refrigerant pipeline is embedded in the condensation end 1111.
[0040] Furthermore, if it is monitored that the actual module temperature (K measured) of the electronic control module is greater than or equal to the first temperature limit value (K1), calculate the expansion valve opening degree according to the actual module temperature and the predetermined temperature limit value, and open the subcooler electronic expansion valve 115 on the refrigerant pipeline to the calculated expansion valve opening degree. Further, it can be made that the refrigerant flows through the condensation end 1111 via the refrigerant pipeline according to the flow rate restricted by this expansion valve opening degree. Then, after the vapor flow reaches the section of the pipe on the condensation end 1111 side, the cold quantity of the refrigerant can be further used to assist the vapor flow in condensing into a liquid, and then assist the heat pipe radiator 111 in better dissipating heat from the electronic control module 114.
[0041] Further continuously detect the actual temperature of the electronic control module. If it is monitored that the actual temperature of the electronic control module is lower than the second temperature limit value (the second temperature limit value is less than or equal to the first temperature limit value), it indicates that continuing to use the refrigerant for auxiliary heat dissipation will cause a risk of condensation on the electronic control module. Then, close the electronic expansion valve of the subcooler, end the auxiliary of the refrigerant to the heat pipe radiator, and only let the heat pipe radiator dissipate heat by itself, so as to avoid condensation caused by the too low temperature of the electronic control module.
[0042] In addition, when using only the heat pipe radiator for heat dissipation, in order to ensure high-temperature heat dissipation, the size of the heat dissipation substrate of the heat pipe radiator needs to be relatively large, resulting in high costs, large installation space occupation, and long heat pipe flow paths. In the embodiment of the present application, by cooperating the heat pipe radiator and the refrigerant, the size of the heat dissipation substrate can be reduced, the cost can be lowered, the installation space occupation can be reduced, and the heat pipe flow path can be shortened.
[0043] In summary, in the way of the embodiment of the present application, by cooperating the heat pipe radiator and the refrigerant in the subcooling section of the outdoor unit, in complex working conditions such as high humidity and high temperature, not only the heat dissipation efficiency of the electronic control module is significantly improved, the module temperature is effectively reduced, but also condensation is successfully avoided, thus taking into account the effective heat dissipation and anti-condensation of the electronic control module, and improving the reliability and stability of the air conditioning system.
[0044] Next, specific optional embodiments of each step in the heat dissipation control of the air conditioner in the foregoing embodiment will be described.
[0045] In one embodiment, calculating the expansion valve opening according to the actual module temperature and the first temperature limit value may specifically include: subtracting the first temperature limit value from the actual module temperature to obtain a temperature difference; multiplying the temperature difference by a predetermined coefficient to obtain an adjustment value; and adding the adjustment value to a predetermined opening value to obtain the expansion valve opening.
[0046] Specifically, in this embodiment, the expansion valve opening can be calculated according to the formula P = A + (K actual - K1) * S, where P is the expansion valve opening, K actual is the actual module temperature, K1 is the first temperature limit value, S is the predetermined coefficient, A is the predetermined opening value, (K actual - K1) * S is the adjustment value, and K actual - K1 is the temperature difference. The applicant has found that calculating the expansion valve opening in the way of this embodiment and opening the electronic expansion valve of the subcooler on the refrigerant pipeline to the expansion valve opening can further avoid condensation as much as possible while effectively assisting heat dissipation. Among them, in one specific example, A = 150 and S = 20; in other examples, the values of A and S can be set according to actual situations.
[0047] Optionally, in other embodiments, calculating the opening degree of the expansion valve according to the actual temperature of the module and the first temperature limit value may include: subtracting the actual temperature of the module from the first temperature limit value to obtain a temperature difference; then, querying a predetermined opening degree corresponding to the temperature difference from a predetermined opening degree table as the opening degree of the expansion valve.
[0048] Further, in one embodiment, the oil return pipeline of the compressor passes through the evaporation end of the heat pipe radiator; the method further includes: controlling the opening or closing of the oil return pipeline solenoid valve in the oil return pipeline according to the actual temperature of the electronic control module, so as to dissipate heat from the oil return flowing through the evaporation end via the oil return pipeline through the heat pipe radiator.
[0049] Refer to Figure 1 , the oil return pipeline 1131 of the compressor 113 passes through the evaporation end 1112 of the heat pipe radiator 111, continuously detecting the actual temperature of the electronic control module, and controlling the opening or closing of the oil return pipeline solenoid valve 116 in the oil return pipeline according to the actual temperature of the electronic control module. When the actual temperature of the module meets a predetermined condition, the oil return pipeline solenoid valve 116 can be opened to enable the oil return to flow through the evaporation end 1112 via the oil return pipeline, so that a section of the heat pipe 1113 on the side of the evaporation end 1112 also absorbs the heat of the oil return in the oil return pipeline, and the heat pipe radiator dissipates heat from the oil return flowing through the evaporation end via the oil return pipeline.
[0050] By means of this embodiment, it is avoided that the oil return at high temperature directly returns to the suction side of the compressor, resulting in overheating of the suction temperature, and it is avoided that the suction volume of the compressor decreases, resulting in a decrease in the refrigeration capacity. Moreover, to a certain extent, heat can be provided by the high-temperature oil return, avoiding that the evaporation end 1112 of the heat pipe radiator absorbs too much heat from the electronic control module 114, causing the temperature of the electronic control module to be too low to generate condensation, and further preventing condensation of the electronic control module to a certain extent.
[0051] Among them, the oil return pipeline of the compressor passing through the evaporation end of the heat pipe radiator may be that the oil return pipeline passes through from above, inside or below the evaporation end, and passing through inside means that the oil return pipeline is embedded in the evaporation end.
[0052] In one embodiment, controlling the opening or closing of the oil return pipeline solenoid valve in the oil return pipeline according to the actual temperature of the electronic control module may include:
[0053] When it is monitored that the actual temperature of the electronic control module is less than the third temperature limit value, the oil return pipeline solenoid valve is opened, and the third temperature limit value is less than the first temperature limit value;
[0054] When it is detected that the actual temperature of the electronic control module rises to the fourth temperature limit value, the solenoid valve of the oil return pipeline is closed, and the fourth temperature limit value is greater than the third temperature limit value.
[0055] When it is detected that the actual temperature of the electronic control module is lower than the third temperature limit value (the third temperature limit value is lower than the first temperature limit value), the solenoid valve of the oil return pipeline is opened, so that the oil return flows through the evaporation end 1112 via the oil return pipeline, and a section of the heat pipe 1113 on the side of the evaporation end 1112 also absorbs the heat of the oil return in the oil return pipeline, and the heat of the oil return flowing through the evaporation end via the oil return pipeline is dissipated by the heat pipe radiator. At this time, the actual temperature of the electronic control module is lower than the third temperature limit value, indicating that the temperature of the electronic control module is relatively low. By cooling the oil return, the temperature of the electronic control module is prevented from being too high, ensuring the safety of the electronic control module while cooling the oil return.
[0056] Furthermore, when it is detected that the actual temperature of the electronic control module rises to the fourth temperature limit value (the fourth temperature limit value is greater than the third temperature limit value), the solenoid valve of the oil return pipeline is closed, and the oil return flow is stopped to further prevent the temperature of the electronic control module from being too high due to the oil return temperature, ensuring the safety of the electronic control module while cooling the oil return.
[0057] In an embodiment, two compressors and two heat pipe radiators are included in the outdoor unit. The electronic control modules of each compressor are respectively arranged on one heat pipe radiator, and the oil return pipelines of each compressor respectively pass through the evaporation end of the heat pipe radiator where the electronic control module of another compressor is located. When it is detected that the actual temperature of the electronic control module is lower than the second temperature limit value, opening the solenoid valve of the oil return pipeline may include: when it is detected that the actual temperature of the electronic control module of the first compressor is lower than the second temperature limit value, opening the solenoid valve of the oil return pipeline in the oil return pipeline of the second compressor; when it is detected that the actual temperature of the electronic control module of the second compressor is lower than the second temperature limit value, opening the solenoid valve of the oil return pipeline in the oil return pipeline of the first compressor; correspondingly, when it is detected that the actual temperature of the electronic control module rises to the third temperature limit value, closing the solenoid valve of the oil return pipeline may include: when it is detected that the actual temperature of the electronic control module of the first compressor rises to the third temperature limit value, closing the solenoid valve of the oil return pipeline in the oil return pipeline of the second compressor; when it is detected that the actual temperature of the electronic control module of the second compressor rises to the third temperature limit value, closing the solenoid valve of the oil return pipeline in the oil return pipeline of the first compressor.
[0058] In this embodiment, combined with Figure 5 , the outdoor unit includes two compressors and two heat pipe radiators. The two compressors can be the first compressor 310 and the second compressor 320 as shown in Figure 5 respectively, and the two heat pipe radiators can be respectively as shown inFigure 5 The first heat pipe radiator 330 and the second heat pipe radiator 340 shown. Further, the electronic control modules of each compressor are respectively arranged on a heat pipe radiator. For example, Figure 5 as shown, the first electronic control module 350 of the first compressor 310 is arranged on the first heat pipe radiator 330, and the second electronic control module 360 of the second compressor 320 is arranged on the second heat pipe radiator 340. Further, the oil return pipelines of each compressor respectively pass through the evaporation end of the heat pipe radiator where the electronic control module of another compressor is located. For example, Figure 5 as shown, the oil return pipeline of the first compressor 310 passes through the evaporation end of the second heat pipe radiator 340 where the second electronic control module 360 of the second compressor 320 is located, and the oil return pipeline of the second compressor 320 passes through the evaporation end of the first heat pipe radiator 330 where the first electronic control module 350 of the first compressor 310 is located.
[0059] Further, in this embodiment, the step of "when it is monitored that the actual temperature of the module of the electronic control module is less than the second temperature limit value, the oil return pipeline solenoid valve is opened" may specifically be: when it is monitored that the actual temperature of the module of the electronic control module of the first compressor 310 (such as Figure 5 the first electronic control module 350 in) is less than the second temperature limit value, the oil return pipeline solenoid valve 370 in the second oil return pipeline 321 of the second compressor 320 is opened; when it is monitored that the actual temperature of the module of the electronic control module of the second compressor 320 (such as Figure 5 the second electronic control module 360 in) is less than the second temperature limit value, the oil return pipeline solenoid valve 380 in the first oil return pipeline 311 of the first compressor 310 is opened.
[0060] Correspondingly, the step of "when it is monitored that the actual temperature of the module of the electronic control module rises back to the third temperature limit value, the oil return pipeline solenoid valve is closed" may specifically be: when it is monitored that the actual temperature of the module of the electronic control module of the first compressor 310 (such as Figure 5 the first electronic control module 350 in) rises back to the third temperature limit value, the oil return pipeline solenoid valve 370 in the second oil return pipeline of the second compressor 320 is closed; when it is monitored that the actual temperature of the module of the electronic control module of the second compressor 320 (such as Figure 5 the second electronic control module 360 in) rises back to the third temperature limit value, the oil return pipeline solenoid valve 380 in the first oil return pipeline of the first compressor 310 is closed.
[0061] In the manner of this embodiment, the oil return pipelines of the compressors respectively pass through the evaporation ends of the heat pipe radiators where the electronic control modules of the other compressors are located. That is, the oil return pipelines of the two compressors cross through the evaporation ends of the two heat pipe radiators. When only one of the two compressors is operating, the "oil return in the oil return pipeline of the operating compressor" can be cooled by the "heat pipe radiator where the electronic control module of the non-operating compressor is located", which can achieve better oil return heat dissipation and is not restricted by the temperature of the electronic control module of the operating compressor.
[0062] Further, in combination with Figure 5 , when the outdoor unit includes two such compressors and two such heat pipe radiators, the refrigerant pipeline of the subcooler can pass through the condensation ends of the two heat pipe radiators. As Figure 5 shown, in the outdoor unit, the refrigerant pipeline 391 of the subcooler 390 passes through the condensation end of the first heat pipe radiator 330 and passes through the condensation end of the second heat pipe radiator 340.
[0063] It can be understood that referring to Figure 5 , the outdoor unit of the air conditioner may further include components such as a four-way valve 3100, an oil separator 3110, a gas separator 3120, an outdoor heat exchanger 3130, and an outdoor fan 3140; the indoor unit may include components such as an indoor heat exchanger 3150.
[0064] In addition, the embodiment of the present application further provides a heat dissipation control device for an air conditioner, and the heat dissipation control device for an air conditioner can be applied to a control device. As Figure 6 shown, Figure 6 shows a block diagram of a heat dissipation control device for an air conditioner according to an embodiment of the present application. Specifically: the heat dissipation control device 400 for an air conditioner may include a processor 401 with one or more processing cores and a memory 402 with one or more computer-readable storage media.
[0065] The processor 401 can, according to instructions, load the executable files corresponding to the processes of one or more computer programs into the memory 402, and the processor 401 runs the computer programs stored in the memory 402, so as to implement various functions in the embodiments of the heat dissipation control method for the air conditioner described above in the present application.
[0066] For example, the processor 401 may execute the following steps: If it is detected that the actual temperature of the electronic control module is greater than or equal to the first temperature limit value, calculate the expansion valve opening degree according to the actual temperature of the module and the first temperature limit value: Open the subcooler electronic expansion valve on the refrigerant pipeline to the expansion valve opening degree, so that the refrigerant flows through the condensation end via the refrigerant pipeline to assist the heat pipe radiator to dissipate heat from the electronic control module; If it is detected that the actual temperature of the electronic control module is less than the second temperature limit value, close the subcooler electronic expansion valve, and the second temperature limit value is less than or equal to the first temperature limit value.
[0067] Those of ordinary skill in the art can understand that all or part of the steps in the various methods of the above embodiments can be completed by a computer program, or by a computer program controlling relevant hardware. The computer program can be stored in a computer-readable storage medium and loaded and executed by a processor.
[0068] Therefore, an embodiment of the present application further provides a storage medium, in which a computer program is stored. The computer program can be loaded by a processor to execute the steps in any one of the methods provided by the embodiments of the present application.
[0069] Among them, the storage medium may be a computer-readable storage medium, and the storage medium may include: read-only memory (ROM, Read Only Memory), random access memory (RAM, Random Access Memory), magnetic disk or optical disk, etc.
[0070] Since the computer program stored in the storage medium can execute the steps in any one of the methods provided by the embodiments of the present application, the beneficial effects that can be achieved by the methods provided by the embodiments of the present application can be realized. For details, see the previous embodiments and will not be repeated here.
