[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application. In addition, it should be understood that the specific implementation described herein is only used to illustrate and explain the present application, and is not used to limit the present application. In the present application, the orientation words such as "upper" and "lower" generally refer to the upper and lower directions of the device in the actual use or working state, and specifically refer to the directions of the drawing surface in the drawings; and "inner" and "outer" refer to the contour of the device. Meanwhile, in the description of the embodiments of the present application, the terms "first", "second", etc. are only used for distinction, and cannot be understood as indicating or implying relative importance. Therefore, the features limited by "first" and "second" can be explicitly or implicitly included one or more features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0031] According to the background description of the present application, with the rapid development of the Internet, the number of base stations is also increasing, and the safety of base station air conditioners is also attracting more and more attention. The base station air conditioner is mainly used to cool the equipment in the base station and provide a suitable operating environment.

[0032] The base station air conditioner needs to run all year round, therefore, in order to ensure that the base station air conditioner can run stably for a long time, the base station control mainboard generally uses refrigerant cooling, that is, the refrigerant flowing into the radiator of the mainboard is used to cool the mainboard. However, especially in the low-temperature refrigeration mode of the air conditioner, the temperature of the refrigerant entering the radiator is too low, which causes the mainboard to condense and further causes the mainboard to burn out. Therefore, it is necessary to control the temperature of the refrigerant entering the radiator to prevent the safety hazard of burning the mainboard.

[0033] In order to solve the above problems, the present application provides an air conditioner, an air conditioner mainboard cooling method and device, an electronic equipment and a computer readable storage medium, which adjusts the temperature of the refrigerant entering the radiator, avoids the phenomenon of condensation of the mainboard caused by too low temperature of the refrigerant entering the radiator in the low-temperature refrigeration mode of the air conditioner, and prevents the mainboard from burning out.

[0034] Specifically, the present embodiment provides an air conditioner, which comprises:

[0035] a compressor, a condenser, a heat exchanger, an evaporator, a control mainboard and a radiator of the control mainboard;

[0036] The compressor, the condenser, the heat exchanger, the evaporator and the radiator form a refrigerant circulation loop;

[0037] The condenser is connected in parallel with the bypass pipeline, and a solenoid valve is installed in the bypass pipeline;

[0038] The refrigerant from the compressor enters the heat exchanger through the condenser and the bypass pipe, so that the refrigerant discharged from the compressor and the refrigerant discharged from the condenser exchange heat in the heat exchanger, and then enters the radiator through the heat exchanger to dissipate heat from the control board.

[0039] In this embodiment, as Figure 1 As shown, the evaporator, compressor, condenser, heat exchanger, radiator of the control board, and electronic expansion valve form a refrigerant circulation loop. Additionally, this embodiment includes a bypass line connected in parallel with the condenser, allowing the refrigerant discharged from the compressor to flow in two directions: one to the condenser and the other to the bypass line, where it converges at the heat exchanger. In this embodiment, the radiator can be located at...

[0040] A solenoid valve is installed on the bypass pipeline. This solenoid valve can be adjustable or non-adjustable. For adjustable valves, the opening degree can be adjusted; for non-adjustable valves, there are only open and closed states. The solenoid valve is used to regulate the amount of refrigerant flowing into the heat exchanger from the bypass pipeline, allowing the refrigerant flowing out of the bypass pipeline and condenser to exchange heat in the heat exchanger. After heat exchange, the refrigerant flows into the heat sink, which then controls the main control board of the air conditioner. Figure 1 (Not shown in the image) for heat dissipation.

[0041] It is understood that in this embodiment, the refrigerant in the bypass pipe is a high-temperature, high-pressure gaseous refrigerant discharged from the compressor, while the refrigerant discharged from the condenser is a low-temperature, low-pressure liquid refrigerant. Therefore, the high-temperature, high-pressure gaseous refrigerant and the low-temperature, low-pressure liquid refrigerant can exchange heat in the heat exchanger, so that the temperature of the liquid refrigerant flowing out of the heat exchanger is significantly higher than that of the liquid refrigerant discharged directly from the condenser. The liquid refrigerant after heat exchange then flows into the radiator to dissipate heat from the air conditioner's control board.

[0042] It is worth noting that in this embodiment, the amount of high-temperature and high-pressure gaseous refrigerant entering the heat exchanger can be adjusted by the opening degree of the solenoid valve, so as to avoid the refrigerant flowing out of the heat exchanger being too hot, which would cause the liquid refrigerant to be too hot and burn out the control board.

[0043] In one embodiment, the air conditioner further includes:

[0044] External pipe temperature sensor and / or refrigerant temperature sensor;

[0045] The outer pipe temperature sensor is arranged at an outlet position of the condenser in the refrigerant circulation loop, and is arranged on a surface of a pipe of the refrigerant circulation loop, for example, to collect an operating temperature of an outer pipe at the outlet of the condenser, which can represent a temperature of refrigerant in the pipe, and to control a state of the electromagnetic valve in the bypass pipe according to the temperature, for example, to control an open state, a closed state, or an opening degree of the electromagnetic valve.

[0046] The refrigerant temperature sensor is arranged on a surface of a pipe between the heat exchanger and the radiator in the refrigerant circulation loop, for example, to collect a refrigerant temperature of refrigerant in the pipe after flowing out of the heat exchanger and before flowing into the radiator.

[0047] In the embodiment, as shown in Figure 1 The outer pipe temperature sensor is arranged at an outlet position of the condenser in the refrigerant circulation loop, and is arranged on a surface of a pipe of the refrigerant circulation loop, for example, to collect an operating temperature of an outer pipe at the outlet of the condenser, which can represent a temperature of refrigerant in the pipe, and to control a state of the electromagnetic valve in the bypass pipe according to the temperature, for example, to control an open state, a closed state, or an opening degree of the electromagnetic valve.

[0048] In addition, the refrigerant temperature sensor is arranged on a surface of a pipe between the heat exchanger and the radiator in the refrigerant circulation loop, for example, to collect a refrigerant temperature of refrigerant in the pipe after flowing out of the heat exchanger and before flowing into the radiator.

[0049] Specifically, for example, as shown in Figure 1 The outer pipe temperature sensor in the embodiment can be an outer pipe temperature bulb, and the refrigerant temperature sensor can be a refrigerant temperature bulb.

[0050] Therefore, compared with the existing air conditioner control mainboard heat dissipation mode, in the embodiment, on the basis of the original refrigerant circulation loop formed by the evaporator, the evaporator, the compressor, the condenser, the heat exchanger, the radiator, and the electronic expansion valve, a bypass pipe is additionally arranged in parallel with the condenser, so that the gaseous refrigerant discharged by the compressor flows to the condenser in one path and flows to the bypass pipe in another path. By controlling the electromagnetic valve, the high-temperature and high-pressure gaseous refrigerant discharged by the compressor flows to the condenser in one path and flows to the bypass pipe in another path. The low-temperature and low-pressure liquid refrigerant flowing out of the condenser exchanges heat with the high-temperature and high-pressure gaseous refrigerant discharged by the compressor in the heat exchanger, so as to increase the temperature of the liquid refrigerant and avoid that the temperature of the refrigerant flowing from the heat exchanger into the radiator is too low. The embodiment can ensure that the control mainboard operates at an appropriate temperature, and can also avoid that condensation occurs on the surface of the control mainboard, the mainboard is burned out, and the normal operation of the air conditioner is affected.

[0051] In an embodiment, the embodiment also provides an air conditioner mainboard heat dissipation method, which can be applied to the air conditioner in the above-mentioned embodiments. In addition, the method can also be applied to electronic equipment, which can be an air conditioner or a network device such as a server.

[0052] Specifically, the air conditioner mainboard heat dissipation method in the embodiment includes the following steps as shown in the following figure: Figure 2

[0053] S10, acquiring an outdoor environment temperature;

[0054] In the embodiment, the air conditioner is in a low-temperature refrigeration mode, and the refrigerant flowing into the radiator has a very low temperature. At this time, if the low-temperature refrigerant flowing out of the condenser is directly used to dissipate heat of the control mainboard, the control mainboard has a risk of condensation. Therefore, the air conditioner in the embodiment can acquire the outdoor environment temperature in advance, and determine whether to enter a special low-temperature refrigeration mode according to the outdoor environment temperature as shown in the following figure: Figure 3

[0055] It can be understood that in the embodiment, the air conditioner in the embodiment can have two low-temperature refrigeration modes: a special low-temperature refrigeration mode and a general low-temperature refrigeration mode. In the special low-temperature refrigeration mode, the refrigerant temperature is too low, and the control mainboard surface has a risk of condensation. The air conditioner in the embodiment can execute the air conditioner mainboard heat dissipation strategy in advance. In the general low-temperature refrigeration mode, the refrigerant temperature is not low enough to cause the control mainboard to have a condensation problem, and the air conditioner can normally refrigerate.

[0056] S20, acquiring a running temperature of an air conditioner outer pipe if the outdoor environment temperature is lower than a preset environment temperature threshold value;

[0057] S30, opening an electromagnetic valve of the air conditioner if the running temperature is lower than a preset pipe temperature threshold value, so that the refrigerant discharged by a compressor of the air conditioner enters a heat exchanger of the air conditioner, and the refrigerant discharged by the compressor and the refrigerant discharged by a condenser of the air conditioner perform heat exchange in the heat exchanger;

[0058] In the embodiment, after the air conditioner acquires the outdoor environment temperature, the air conditioner can determine whether the outdoor environment temperature is lower than the preset environment temperature threshold value. If it is determined that the outdoor environment temperature is lower than the preset environment temperature threshold value, the air conditioner can enter the special low-temperature refrigeration mode. In the mode, the air conditioner can acquire the running temperature of the air conditioner outer pipe as shown in the following figure: Figure 3

[0059] It can be understood that in the embodiment, in the special refrigeration mode, the liquid refrigerant flowing out of the condenser has a low temperature. At this time, the air conditioner can acquire the running temperature of the air conditioner outer pipe through an outer pipe temperature sensor. According to the above embodiment, the outer pipe temperature sensor can be installed at an outlet position of the condenser in the refrigerant circulation loop, for example, can be installed on the surface of the refrigerant circulation loop pipe at the outlet position, to acquire the running temperature of the outer pipe at the outlet of the condenser. The running temperature can represent the refrigerant temperature in the pipe. If the above running temperature is lower than the preset pipe temperature threshold value, it means that the refrigerant temperature flowing out of the condenser is too low, and the control mainboard has a risk of condensation.

[0060] At this time, the air conditioner can​​​Figure 3 As shown, the air conditioner can open the electromagnetic valve. According to the above description, the electromagnetic valve is installed in the bypass pipeline in the present embodiment. When the air conditioner detects that the operating temperature of the air conditioner outer pipeline is lower than the preset pipeline temperature threshold, the air conditioner opens the electromagnetic valve, so that the high-temperature and high-pressure gaseous refrigerant discharged by the compressor flows to the condenser in one way, and flows to the bypass pipeline through the opened electromagnetic valve in another way. The low-temperature and low-pressure liquid refrigerant flowing out of the condenser exchanges heat with the high-temperature and high-pressure gaseous refrigerant discharged by the compressor in the heat exchanger, so as to increase the temperature of the liquid refrigerant. The refrigerant after heat exchange flows into the radiator, and the control mainboard (not shown) of the air conditioner is cooled. Figure 1

[0061] S40, the refrigerant after heat exchange in the heat exchanger flows into the radiator of the air conditioner, and the control mainboard is cooled according to the refrigerant after heat exchange in the radiator.

[0062] In the present embodiment, after the air conditioner opens the electromagnetic valve, the low-temperature and low-pressure liquid refrigerant flowing out of the condenser exchanges heat with the high-temperature and high-pressure gaseous refrigerant discharged by the compressor in the heat exchanger. Further, the air conditioner can control the refrigerant after heat exchange to flow into the radiator, so as to cool the control mainboard.

[0063] For example, the air conditioner can control the blocking device in heat exchange to be closed for a preset time, so that the low-temperature and low-pressure liquid refrigerant flowing out of the condenser exchanges heat with the high-temperature and high-pressure gaseous refrigerant discharged by the compressor in the heat exchanger. The blocking device can be installed at the outlet position of the heat exchanger, and the blocking device is opened after the heat exchange for the preset time. The present embodiment does not specifically limit the structure of the blocking device, which can be a mechanical structure, for example.

[0064] In another embodiment, no blocking device can be arranged in the heat exchanger, so that the low-temperature and low-pressure liquid refrigerant flowing out of the condenser exchanges heat with the high-temperature and high-pressure gaseous refrigerant discharged by the compressor in the heat exchanger, and then flows into the radiator. At this time, the temperature of the liquid refrigerant flowing into the radiator is also relatively low, and the air conditioner mainboard does not have the risk of condensation.

[0065] ​It can be seen that in the present embodiment, the air conditioner can collect the outdoor environment temperature, determine that the outdoor environment temperature is lower than the preset environment temperature threshold, and enter the special low-temperature refrigeration mode. In this mode, the air conditioner can obtain the operating temperature of the air conditioner outer pipe. When the air conditioner detects that the operating temperature of the air conditioner outer pipe is lower than the preset pipe temperature threshold, the electromagnetic valve is opened, so that the high-temperature and high-pressure gaseous refrigerant discharged by the compressor flows to the condenser, and the other part flows to the bypass pipeline through the opened electromagnetic valve. The low-temperature and low-pressure liquid refrigerant flowing out of the condenser exchanges heat with the high-temperature and high-pressure gaseous refrigerant discharged by the compressor in the heat exchanger, and the air conditioner can control the refrigerant after heat exchange to flow into the radiator to dissipate heat for the control mainboard. Therefore, the bypass pipeline is added, which is connected with the condenser in parallel, so that the gaseous refrigerant discharged by the compressor flows to the condenser in the present embodiment. The bypass pipeline is connected with the condenser in parallel, and the high-temperature and high-pressure gaseous refrigerant discharged by the compressor flows to the bypass pipeline through the control of the electromagnetic valve. The low-temperature and low-pressure liquid refrigerant flowing out of the condenser exchanges heat with the high-temperature and high-pressure gaseous refrigerant discharged by the compressor in the heat exchanger, so as to improve the temperature of the liquid refrigerant and avoid that the temperature of the refrigerant flowing into the radiator from the heat exchanger is too low. The present embodiment can not only ensure that the control mainboard operates at an appropriate temperature, but also can avoid the condensation phenomenon on the surface of the control mainboard, burn out the mainboard and affect the normal operation of the air conditioner.

[0066] In an embodiment, after the above S40, "dissipating heat for the control mainboard according to the refrigerant after heat exchange in the radiator", the air conditioner can further include:

[0067] S50, obtaining the refrigerant temperature of the refrigerant in the pipeline between the heat exchanger and the radiator;

[0068] S60, if the refrigerant temperature is greater than the preset refrigerant temperature threshold, closing the electromagnetic valve;

[0069] S70, if the refrigerant temperature is less than the preset refrigerant temperature threshold, controlling the electromagnetic valve to remain in the opened state until the refrigerant temperature is greater than the preset refrigerant temperature threshold, and then closing the electromagnetic valve.

[0070] In the present embodiment, the refrigerant after heat exchange in the heat exchanger flows into the radiator of the air conditioner, and after dissipating heat for the control mainboard according to the refrigerant after heat exchange in the radiator, the air conditioner can again collect the refrigerant temperature of the refrigerant in the pipeline between the heat exchanger and the radiator through the refrigerant temperature sensor.

[0071] If it is detected that the refrigerant temperature is greater than the preset refrigerant temperature threshold, it means that the temperature of the refrigerant after heat exchange is high at this time, and the refrigerant flowing into the radiator will not cause the control mainboard of the air conditioner to appear condensation phenomenon. Therefore, the air conditioner can close the electromagnetic valve, so that the high-temperature and high-pressure gaseous refrigerant discharged by the compressor will not enter the bypass pipeline. At this time, the air conditioner is in the ordinary low-temperature refrigeration mode.

[0072] If the refrigerant temperature is detected to be less than the preset refrigerant temperature threshold, it means that the refrigerant flowing into the radiator is still likely to cause condensation on the control mainboard of the air conditioner at this time. Therefore, the air conditioner can control the electromagnetic valve to remain open until the refrigerant temperature of the refrigerant in the pipeline between the heat exchanger and the radiator is detected by the refrigerant temperature sensor to be greater than the preset refrigerant temperature threshold, and the electromagnetic valve is closed.

[0073] In the above S30, “if the operating temperature is lower than the preset pipe temperature threshold, the electromagnetic valve is opened, so that the refrigerant discharged by the compressor enters the heat exchanger, and the refrigerant discharged by the compressor and the refrigerant discharged by the condenser are heat exchanged in the heat exchanger”, can include:

[0074] S301, if the operating temperature is lower than the preset pipe temperature threshold, the corresponding electromagnetic valve opening degree is obtained according to the operating temperature by querying the preset electromagnetic valve opening degree mapping table;

[0075] S302, the electromagnetic valve is controlled to open according to the electromagnetic valve opening degree, so that the refrigerant discharged by the compressor enters the heat exchanger, and the refrigerant discharged by the compressor and the refrigerant discharged by the condenser are heat exchanged in the heat exchanger.

[0076] In this embodiment, after the air conditioner collects the operating temperature of the outer pipe of the air conditioner through the outer pipe temperature sensor, according to the above description, the operating temperature can represent the refrigerant temperature in the outer pipe of the air conditioner. If the operating temperature is lower than the preset pipe temperature threshold, it means that the refrigerant flowing out of the condenser is too low in temperature, and there is a risk of condensation on the control mainboard. At this time, the air conditioner can query the preset electromagnetic valve opening degree mapping table according to the above operating temperature to obtain the corresponding electromagnetic valve opening degree.

[0077] In the preset electromagnetic valve opening degree mapping table, the mapping relationship between the operating temperature of the outer pipe of the air conditioner and the electromagnetic valve opening degree is included, and each operating temperature has a corresponding electromagnetic valve opening degree.

[0078] Further, the air conditioner can control the electromagnetic valve to open according to the electromagnetic valve opening degree obtained by the above table lookup, so that the refrigerant discharged by the compressor and the refrigerant discharged by the condenser are heat exchanged in the heat exchanger, and the refrigerant temperature is increased.

[0079] After the above S50, “obtaining the refrigerant temperature of the refrigerant in the pipeline between the heat exchanger and the radiator”, can further include:

[0080] S80, obtaining the ambient temperature and the ambient humidity of the environment in which the control mainboard is located;

[0081] S90, calculating the condensation temperature of the control mainboard according to the ambient temperature and the ambient humidity.

[0082] S100, adjusting the opening degree of the electromagnetic valve according to the condensation temperature and the refrigerant temperature.

[0083] In the embodiment, the refrigerant after heat exchange in the heat exchanger flows into the radiator of the air conditioner, and the control mainboard is cooled according to the refrigerant after heat exchange in the radiator. The air conditioner can collect the refrigerant temperature of the refrigerant in the pipeline between the radiator and the heat exchanger through the refrigerant temperature sensor, and further, the air conditioner can obtain the ambient temperature and the ambient humidity of the environment where the control mainboard is located through the temperature sensor and the humidity sensor.

[0084] The air conditioner can calculate the condensation temperature of the control mainboard according to the ambient temperature and the ambient humidity.

[0085] It can be understood that the condensation temperature (i.e. the dew point temperature) refers to the temperature at which the water vapor in the air begins to condense into liquid water when the air is saturated at a certain pressure. When the air is cooled to equal to or lower than its dew point temperature, the water vapor begins to condense into water droplets or dew.

[0086] Further, the air conditioner can adjust the opening degree of the electromagnetic valve according to the condensation temperature and the refrigerant temperature.

[0087] Specifically, for example, if the air conditioner detects that the refrigerant temperature of the refrigerant in the pipeline between the heat exchanger and the radiator is lower than the condensation temperature, it means that the refrigerant flowing into the radiator will cause the control mainboard to condense, resulting in a risk of burning the control mainboard. Therefore, the air conditioner can increase the opening degree of the electromagnetic valve, so that the amount of high-temperature and high-pressure gaseous refrigerant flowing into the heat exchanger of the compressor increases, intensifying the heat exchange between the refrigerants, so that the refrigerant temperature is significantly improved, avoiding the refrigerant temperature flowing into the radiator being too low to cause the control mainboard to condense.

[0088] After the above S60, "if the refrigerant temperature is greater than the preset refrigerant temperature threshold, the electromagnetic valve is closed", the method can further include:

[0089] S110, obtaining a temperature difference between the refrigerant temperature and the preset refrigerant temperature threshold;

[0090] S120, if the temperature difference is greater than a preset temperature difference threshold, obtaining an actual operating frequency of the compressor;

[0091] S130, if the actual operating frequency is lower than a preset refrigeration frequency threshold, controlling the compressor to operate at a higher frequency until the operating temperature is lower than a preset pipe temperature threshold, and the electromagnetic valve is opened.

[0092] It should be noted that in the embodiment, according to the above description, on the basis of the original refrigerant circulation circuit formed by the evaporator, the evaporator, the compressor, the condenser, the heat exchanger, the radiator and the electronic expansion valve, the bypass pipeline is newly added, the bypass pipeline is connected in parallel with the condenser, by controlling the electromagnetic valve, the high temperature and high pressure gaseous refrigerant discharged by the compressor flows to the condenser in one way, and flows to the bypass pipeline in the other way, the low temperature and low pressure liquid refrigerant flowing out of the condenser exchanges heat with the high temperature and high pressure gaseous refrigerant discharged by the compressor in the heat exchanger, the temperature of the liquid refrigerant is increased, and the temperature of the refrigerant flowing into the radiator from the heat exchanger is too low, and at the same time, as shown in Figure 1 , the temperature of the heat-exchanged refrigerant flowing into the evaporator is obviously increased, resulting in poor air conditioning refrigeration effect.

[0093] Therefore, the air conditioner can obtain a temperature difference between the refrigerant temperature and the preset refrigerant temperature threshold value, and if the temperature difference is greater than the preset temperature difference threshold value, it means that the temperature of the refrigerant flowing into the evaporator is too high, which affects the refrigeration performance of the air conditioner, at this time, the air conditioner can obtain the actual running frequency of the compressor, and when the actual running frequency is lower than the preset refrigeration frequency threshold value, the compressor is controlled to run at a higher frequency, the refrigerant amount is increased, and the refrigeration effect of the air conditioner is improved, until the running temperature is lower than the preset pipe temperature threshold value, and the electromagnetic valve is restarted.

[0094] Therefore, the embodiment can not only ensure normal refrigeration of the air conditioner and improve the refrigeration performance of the air conditioner, but also avoid the condensation of the control mainboard caused by too low refrigerant, and the burning of the control mainboard.

[0095] The embodiment also provides an air conditioner mainboard heat dissipation device, which can be integrated in an air conditioner, for example, as shown in Figure 4 , the air conditioner mainboard heat dissipation device can include:

[0096] The first acquisition module 1001 is configured to acquire an outdoor environment temperature.
