[0035] Combination Figure 1 and Figure 2 As shown, Figure 1 It is a structural schematic diagram of a heat dissipation device provided in an embodiment of the present disclosure. Figure 21 is a schematic diagram of the internal structure of an outdoor unit of an air conditioner provided by an embodiment of the present disclosure. An electrical component 1 and a heat sink 2 are provided in the outdoor unit of the air conditioner. The heat sink is used to controllably absorb the heat generated by the electrical component when it is running. The heat sink 2 includes an aluminum substrate 3, a throttle valve 4 and a refrigerant heat sink ring 5. The bottom surface of the aluminum substrate 3 is fitted and fixed with the refrigerant heat sink ring 5, and the top surface of the aluminum substrate 3 is fixedly connected to the electrical component through a bracket 6. The aluminum substrate 3 is used to absorb the heat generated when the electrical component is working. One end of the throttle valve 4 is connected to the refrigerant heat sink ring 5, and the other end of the throttle valve 4 is connected to the heat exchanger 7 of the air conditioner. The refrigerant heat sink ring 5 is configured to dissipate heat from the aluminum substrate 3 when the throttle valve 4 is opened. The aluminum substrate 3, the bracket 6, the electrical component and the refrigerant heat sink ring 5 are all arranged in a box 8 in the air conditioner. Among them, a temperature monitoring device is also provided in the box, and the temperature monitoring device is used to monitor the working temperature of the electrical component. In this way, the top surface of the aluminum substrate is fixedly connected to the main control board through the bracket, so that it can absorb the heat generated when the main control board is running. The bottom surface of the aluminum substrate is fitted and fixed to the refrigerant heat dissipation ring, and the aluminum substrate can transfer the heat absorbed from the main control board to the refrigerant heat dissipation ring through heat conduction.

[0036] In some embodiments, the electrical component is a main control board of an outdoor unit of an air conditioner. The main control board includes a main control board working module and a main control board console. The main control board working module is a component that controls the normal operation of the air conditioner and is also the main heat source of the main control board. The main control board console includes a console control module and a data processing module. The data processing module is electrically connected to the console control module, and the console control module is used to send control instructions to the throttle valve in the heat dissipation device.

The throttle valve in the heat dissipation device is controlled by the main control board console.

[0038] Combination Figure 3 As shown, the embodiment of the present disclosure provides a method for controlling a heat dissipation device, comprising:

[0039] Step S301: the air conditioner obtains the temperature monitoring value and input current of the electrical component.

[0040] Step S302: The air conditioner determines a reference temperature threshold value according to the temperature monitoring value and the input current.

[0041] Step S303: the air conditioner controls the throttle valve according to the reference temperature threshold.

[0042] The method for controlling the heat dissipation device provided by the embodiment of the present disclosure is adopted, by obtaining the temperature monitoring value and input current of the electrical component, determining the reference temperature threshold value according to the temperature monitoring value and the input current, and controlling the throttle valve according to the reference temperature threshold value. In this way, by fitting and fixing the refrigerant heat dissipation ring to the bottom surface of the aluminum substrate, and controlling the refrigerant flow in the refrigerant heat dissipation ring through the throttle valve, the heat absorbed by the aluminum substrate can be better dissipated. Thereby, the operating temperature of the electrical component can be reduced in time, and the heat dissipation effect of the electrical component of the air conditioner is improved.

[0043] In some embodiments, a temperature monitoring device is provided on the electrical component, and the air conditioner obtains the temperature monitoring value of the electrical component, including: the air conditioner monitors the working temperature of the electrical component using the temperature detection device to obtain the temperature monitoring value.

[0044] In some embodiments, the air conditioner reads input current from the electrical component.

[0045] Furthermore, the air conditioner determines a reference temperature threshold value according to the temperature monitoring value and the input current, including: the air conditioner obtains an alternative temperature value corresponding to the input current, and determines the reference temperature threshold value according to the temperature monitoring value and the alternative temperature value.

[0046] Optionally, the air conditioner obtains an alternative temperature value corresponding to the input current, including: the air conditioner obtains temperature values ​​corresponding to the same input current under multiple preset working conditions, averages each temperature value, obtains an average temperature value, and determines the average temperature value as the alternative temperature value. In this way, the average temperature of the temperature values ​​corresponding to the multiple preset working conditions is obtained according to the input current. Since the influence of different working conditions on the reference temperature threshold of the air conditioner is taken into account, the alternative temperature value can be determined more accurately by averaging each temperature value under different working conditions. It is convenient to control the throttle valve more accurately and improve the heat dissipation effect of the electrical components.

[0047] In some embodiments, the preset working conditions include: maximum power heating, maximum power cooling, normal heating, normal cooling, minimum power heating or minimum power cooling, etc. Among them, when the compressor power of the air conditioner is within the first preset range during heating, it is normal heating. When the compressor power of the air conditioner is within the second preset range during cooling, it is normal cooling.

[0048] In some embodiments, when the input current is I 1 In the case of the preset working condition, the temperature corresponding to the maximum power heating is T1 ; The preset working condition is the temperature value corresponding to the maximum power cooling is T 2 ; The temperature corresponding to the default working condition of normal heating is T 3 ; The temperature corresponding to the preset working condition of normal cooling is T 4 ; The temperature corresponding to the preset working condition of minimum power heating is T 5 ; The preset working condition is the temperature value corresponding to the minimum power cooling is T 6 Then by calculating Get the average temperature value. Where, T P is the average temperature value.

[0049] Optionally, the air conditioner obtains an alternative temperature value corresponding to the input current, including: the air conditioner matches the alternative temperature value corresponding to the input current from a preset database. The preset database stores the correspondence between the input current and the alternative temperature value. In this way, since the air conditioner may encounter various extreme operating environments during operation, it is easy to cause errors in the temperature monitoring values ​​of the monitored electrical components. If the air conditioner is controlled to dissipate heat only by relying on the temperature monitoring values ​​of the monitored electrical components, it is difficult to accurately dissipate heat for the electrical components, which easily leads to poor heat dissipation effect. By adding the influencing factor of input current, the temperature monitoring value and the alternative temperature value corresponding to the input current are considered when dissipating heat for the electrical components, which can improve the accuracy of the heat dissipation control of the air conditioner. At the same time, by directly storing the alternative temperature value corresponding to the input current in the database in advance, the control efficiency can be improved, thereby achieving more timely heat dissipation of the electrical components.

[0050] Furthermore, the air conditioner determines a reference temperature threshold value based on the temperature monitoring value and the alternative temperature value, including: the air conditioner compares the temperature monitoring value with the alternative temperature value to obtain a comparison result, and when the comparison result is that the alternative temperature value is less than or equal to the temperature monitoring value, the temperature monitoring value is determined as the reference temperature threshold value. Or, when the comparison result is that the alternative temperature value is greater than the temperature monitoring value, the alternative temperature value is determined as the reference temperature threshold value. In this way, by determining the larger of the alternative temperature value and the temperature monitoring value as the reference temperature threshold value, the influence of the inaccurate temperature monitoring value obtained by the air conditioner under extreme working conditions on the heat dissipation control can be reduced as much as possible. Thereby, the throttle valve can be controlled more accurately, and the heat dissipation effect of the electrical components of the air conditioner can be improved.

[0051] Further, the air conditioner controls the throttle valve according to the reference temperature threshold, including: when the reference temperature threshold is greater than or equal to the first preset temperature, the air conditioner obtains a target valve opening corresponding to the reference temperature threshold, and controls the throttle valve to open according to the target valve opening.

[0052] Furthermore, the air conditioner obtains the target valve opening corresponding to the reference temperature threshold, including: the air conditioner matches the target valve opening corresponding to the reference temperature threshold from a preset database. The preset database stores the corresponding relationship between the reference temperature threshold and the target valve opening.

[0053] In some embodiments, the first preset temperature is T 10 , the second preset temperature is T 20 There is also a set temperature T between the first preset temperature and the second preset temperature. 11 , T 12 , T 13 , T 14 , T 15 , T 16 , T 17 , T 18 and T 19 The set temperatures are sorted from small to large, and each set temperature is an arithmetic progression with a difference of 1°C. Each set temperature has a corresponding valve opening in the preset database. Among them, the first preset temperature T 10 The first preset temperature is 40°C and the second preset temperature is 50°C. 11 Set the temperature to 41°C. 12 Set the temperature to 42°C. 13 Set the temperature to 43°C. 14 Set the temperature to 44°C. 15 Set the temperature to 45°C. 16 Set the temperature to 46°C. 17 Set the temperature to 47°C. 18 Set the temperature to 48°C. 19 is 49°C. In this way, the valve opening control of the throttle valve can be increased linearly, thereby realizing the multi-point linear control of the throttle valve on the refrigerant flow, and then realizing the linear control of the temperature of the refrigerant heat dissipation ring, and finally realizing the linear control of the working temperature of the electrical components. Improve the heat dissipation efficiency and heat dissipation stability of the electrical components. At the same time, by timely dissipating the heat of the electrical components, the working stability of the electrical components can also be improved.

[0054] In some embodiments, when the reference temperature threshold is greater than or equal to the first preset temperature and less than the second preset temperature, the air conditioner obtains the target valve opening corresponding to the reference temperature threshold as the first preset valve opening. Then the throttle valve is controlled to open according to the first preset valve opening. In some embodiments, the first preset temperature is 40°C.

[0055] In some embodiments, when the reference temperature threshold is greater than or equal to the second preset temperature, the air conditioner obtains the target valve opening corresponding to the reference temperature threshold as the second preset valve opening. The throttle valve is controlled to open according to the second preset valve opening. Among them, the second preset valve opening is the maximum valve opening, and the second preset valve opening is greater than the first preset valve opening. The second preset temperature is 50°C. In this way, when the reference temperature threshold is greater than or equal to 50°C, the throttle valve is fully opened, and the flow rate entering the refrigerant heat dissipation ring through the throttle valve reaches the maximum value. At this time, the cooling capacity of the refrigerant heat dissipation ring reaches the maximum value.

[0056] Furthermore, the air conditioner controls the throttle valve according to the reference temperature threshold, including: when the reference temperature threshold is less than the first preset temperature, the air conditioner controls the throttle valve to close. In this way, when the reference temperature threshold is less than the first preset temperature, it is considered that the electrical component does not need to dissipate heat at this time. By closing the throttle valve, the refrigerant cannot enter the refrigerant heat dissipation loop, thereby saving energy consumption.

[0057] Combination Figure 4 As shown, an embodiment of the present disclosure provides a method for controlling a heat dissipation device, the heat dissipation device comprising an aluminum substrate, a throttle valve and a refrigerant heat dissipation ring. The bottom surface of the aluminum substrate is fitted and fixed to the refrigerant heat dissipation ring, and the top surface of the aluminum substrate is fixedly connected to the electrical component through a bracket. The aluminum substrate is used to absorb the heat generated when the electrical component is working. One end of the throttle valve is connected to the refrigerant heat dissipation ring, and the other end of the throttle valve is connected to the heat exchanger of the air conditioner. The refrigerant heat dissipation ring is configured to dissipate heat to the aluminum substrate when the throttle valve is opened. The method comprises:

[0058] Step S401: the air conditioner obtains the temperature monitoring value and input current of the electrical component.

[0059] In step S402, the air conditioner obtains temperature values ​​corresponding to the same input current under multiple preset working conditions.

[0060] Step S403: the air conditioner averages each temperature value to obtain an average temperature value, and determines the average temperature value as a candidate temperature value.

[0061] Step S404: the air conditioner determines a reference temperature threshold value according to the temperature monitoring value and the candidate temperature value.

[0062] Step S405: the air conditioner controls the throttle valve according to the reference temperature threshold.

[0063] The method for controlling an air conditioner provided by the embodiment of the present disclosure is adopted. By acquiring the temperature monitoring value and input current of the electrical component, a reference temperature threshold is determined according to the temperature monitoring value and the input current, and the throttle valve is controlled according to the reference temperature threshold. In this way, since the influence of different working conditions on the reference temperature threshold of the air conditioner is taken into account, the alternative temperature value can be determined more accurately by averaging the temperature values ​​under different working conditions. Even if the air conditioner encounters different working conditions, the corresponding reference temperature threshold is determined by simultaneously collecting the temperature monitoring value and input current of the electrical component. This facilitates more accurate control of the throttle valve, thereby enabling more accurate control of the refrigerant flow in the refrigerant heat dissipation ring. This further improves the heat dissipation effect of the electrical components of the air conditioner.

[0064] Combination Figure 5 As shown, an embodiment of the present disclosure provides a method for controlling a heat dissipation device, the heat dissipation device comprising an aluminum substrate, a throttle valve and a refrigerant heat dissipation ring. The bottom surface of the aluminum substrate is fitted and fixed to the refrigerant heat dissipation ring, and the top surface of the aluminum substrate is fixedly connected to the electrical component through a bracket. The aluminum substrate is used to absorb the heat generated when the electrical component is working. One end of the throttle valve is connected to the refrigerant heat dissipation ring, and the other end of the throttle valve is connected to the heat exchanger of the air conditioner. The refrigerant heat dissipation ring is configured to dissipate heat to the aluminum substrate when the throttle valve is opened. The method comprises:

[0065] Step S501: the air conditioner obtains the temperature monitoring value and input current of the electrical component.

[0066] Step S502: the air conditioner obtains a candidate temperature value corresponding to the input current.

[0067] In step S503, the air conditioner determines a larger one of the temperature monitoring value and the candidate temperature value as a reference temperature threshold.

[0068] Step S504: when the reference temperature threshold is greater than or equal to the first preset temperature, the air conditioner obtains a target valve opening corresponding to the reference temperature threshold.

[0069] Step S505: the air conditioner controls the throttle valve to open according to the target valve opening.

[0070] The method for controlling an air conditioner provided by the embodiment of the present disclosure is adopted. By acquiring the temperature monitoring value and input current of the electrical component, a reference temperature threshold is determined according to the temperature monitoring value and the input current, and the heat dissipation device is controlled according to the reference temperature threshold. In this way, even if the air conditioner encounters different working conditions, the temperature monitoring value and input current of the electrical component are collected at the same time, and the corresponding alternative temperature value is obtained according to the input current. A larger one is selected from the temperature monitoring value and the alternative temperature value to be determined as the reference temperature threshold, and the throttle valve is controlled to open according to the corresponding target valve opening when the reference temperature threshold is greater than or equal to the first preset temperature. Thereby, the refrigerant flows into the refrigerant heat dissipation ring to absorb the heat generated by the electrical component during operation. In this way, the heat dissipation effect of the electrical components of the air conditioner can be improved.

Optionally, the device may also include a communication interface 602 and a bus 603.

The processor 604 may call the logic instructions in the memory 601 to execute the method for controlling the heat dissipation device of the above embodiment.

[0072] The device for controlling the heat dissipation device provided by the embodiment of the present disclosure is used to obtain the temperature monitoring value and input current of the electrical component, determine the reference temperature threshold value according to the temperature monitoring value and the input current, and control the throttle valve according to the reference temperature threshold value. In this way, by fitting and fixing the refrigerant heat dissipation ring to the bottom surface of the aluminum substrate and controlling the refrigerant flow in the refrigerant heat dissipation ring through the throttle valve, the heat absorbed by the aluminum substrate can be better dissipated. Thereby, the operating temperature of the electrical component can be reduced in time, and the heat dissipation effect of the electrical component of the air conditioner is improved.
