In general, the temperatures of different positions of the second heat dissipation module may be different, and the first temperature here may be the highest temperature of the surface of the second heat dissipation module, and may also be the temperature of the portion where the superconducting heat pipe contacts the second heat dissipation module. The embodiment does not specifically limit the method for acquiring the first temperature, and for example, the first temperature may be acquired by using a temperature sensor.
And S2, controlling the opening degree of the first electromagnetic expansion valve according to the first temperature.

The "opening degree" herein may include any state of the first electromagnetic expansion valve, including, for example, all states from "closed" to "fully open", and also including both the "closed" and "fully open" states. Specifically, when the first temperature increases, the opening degree of the first electromagnetic expansion valve is increased to increase the flow rate of the refrigerant in the refrigerant pipe in the first heat dissipation module, so that the heat dissipation capacity of the first heat dissipation module is increased. Specifically, the temperature node at which the first electromagnetic expansion valve is "opened" may be a phase transition temperature of the superconducting heat pipe, and the first temperature of the second heat dissipation module may be greater than or equal to the phase transition temperature of the superconducting heat pipe. When the first temperature is equal to the phase change temperature of the superconducting heat pipe, the first electromagnetic expansion valve is opened, and when the first temperature is higher than the phase change temperature of the superconducting heat pipe, the opening degree of the first electromagnetic expansion valve is increased; or if the acquired first temperature is in an increasing trend, the opening degree of the first electromagnetic valve is increased so as to improve the heat dissipation capacity of the first heat dissipation module. For example, the phase transition temperature of the superconducting heat pipe may be 55 ℃, and then the temperature node at which the first electromagnetic expansion valve is opened is 55 ℃; and when the first temperature of the second heat dissipation module is higher than 55 ℃, the opening degree of the first electromagnetic expansion valve is increased.
Further, the aforementioned "obtaining the first temperature of the second heat dissipation module and controlling the opening degree of the first electromagnetic expansion valve according to the first temperature" includes that the temperature of the second heat dissipation module at least includes a first temperature range and a second temperature range, temperature values in the first temperature range are all smaller than temperature values in the second temperature range, the opening degree of the first electromagnetic expansion valve at least includes a first opening degree range corresponding to the first temperature range, and, a second opening degree range corresponding to the second temperature range, wherein the opening degrees in the first opening degree range are all smaller than the opening degrees in the second opening degree range, the current first temperature of the second heat dissipation module is obtained, the current opening degree of the first electromagnetic expansion valve is obtained, and when the conditions that the first temperature falls into the second temperature range and the current opening degree falls into the first opening degree range are met, adjusting the opening degree of the first electromagnetic expansion valve to fall into the second opening degree range.
Specifically, the different temperatures of the second heat dissipation module can be divided into at least two temperature ranges, where the two temperature ranges can be two consecutive range values, for example, the first temperature range can be 55-60 ℃ and not equal to 60 ℃, and the second temperature range can be 60-65 ℃. The first opening degree range may be an opening degree of the first electromagnetic expansion valve that decreases or maintains a temperature value within the first temperature range, and similarly, the second opening degree range may be an opening degree of the first electromagnetic expansion valve that decreases or maintains a temperature value within the second temperature range. In order to better exert the heat dissipation effect of the heat dissipation member, the number of the temperature ranges of the second heat dissipation module is not specifically limited, and may include a first temperature range, a second temperature range, … …, and an nth temperature range, and a first opening range, a second opening range, … …, and an nth opening range of the first electromagnetic expansion valve corresponding to the N temperature ranges are simultaneously set, a temperature range M (M is less than or equal to N) where the first temperature is located and an opening range E where the opening of the current electromagnetic expansion valve is located are obtained, and when M is greater than E (E is less than or equal to N), the opening of the first electromagnetic expansion valve is increased to make the opening of the first electromagnetic expansion valve fall into the mth opening range, or fall into a range greater than the mth opening range, so as to increase the heat dissipation capacity of the first heat dissipation module, and effectively dissipate heat for an object to be dissipated (which may be an inverter module of an air conditioner).

In this embodiment, the method for obtaining the second temperature is not particularly limited, and for example, a temperature sensor may be disposed in the refrigerant pipe to obtain the second temperature of the refrigerant in the refrigerant pipe. The first temperature is higher, the second heat dissipation module receives more heat of the object to be dissipated, and the opening degree of the first electromagnetic expansion valve can be increased when the second temperature of the refrigerant in the refrigerant pipe is higher, so that the heat dissipation capacity of the first heat dissipation module is improved. Specifically, the second temperature of the refrigerant in the refrigerant pipe may be obtained, and when the conditions that the first temperature is greater than the first preset value and the second temperature is greater than the second preset value are met, the opening degree of the first electromagnetic expansion valve is increased.
In the control method provided in the embodiment of the present invention, the first heat dissipation module further includes a check valve, and the control method further includes: when the condition that the air conditioner is in a heating mode is met, the check valve is adopted to prevent the refrigerant from entering the refrigerant pipe.
When the air conditioner indoor unit is in a heating mode, the outdoor environment temperature is low, the heat quantity to be dissipated by the frequency conversion module is small, and the second heat dissipation module can be adopted to dissipate the heat quantity of the frequency conversion module of the air conditioner. At this time, the refrigerant is prevented from entering the refrigerant pipe by the check valve, and further, the first electromagnetic expansion valve is adjusted to a closed state.
In an embodiment of the present invention, the check valve may be installed at a refrigerant inlet of the refrigerant pipe of the first heat dissipation module, and similarly, the first electromagnetic expansion valve may also be installed at the refrigerant inlet of the refrigerant pipe of the first heat dissipation module.
The embodiment of the invention also provides a control device of the air conditioner, and various embodiments in the control method can be introduced into the control device.
As shown in fig. 4, an air conditioner provided in an embodiment of the present invention includes: a compressor 4, a four-way valve 5, an outdoor heat exchanger 6, a first electromagnetic expansion valve 7, a capillary tube 8, a check valve 9, a second electromagnetic expansion valve 10, an indoor heat exchanger 11, and a heat radiation member.
The heat dissipation member in the embodiment of the present invention may include, as shown in fig. 2 and 3: the heat radiator comprises a first heat radiating module 1, a second heat radiating module 2 and a superconducting heat pipe 3, wherein a refrigerant pipe 101 is arranged in the first heat radiating module, and the first heat radiating module is connected with the second heat radiating module through the superconducting heat pipe.

The heat dissipation member including two heat dissipation modules provided in this embodiment employs two heat dissipation modules to dissipate heat of an object to be dissipated, and has high heat dissipation capability. For example, the first heat dissipation module may be a refrigerant heat dissipation form provided with a refrigerant pipe, specifically, heat is transferred to the first heat dissipation module through the superconducting heat pipe for heat dissipation, and cold is transferred to the superconducting heat pipe through the first heat dissipation module by the refrigerant pipe, thereby completing a phase change cycle of the superconducting heat pipe; the second heat dissipation module can be used for air cooling heat dissipation, can adopt a form of contacting with an object to be dissipated, receives heat of the object to be dissipated, and is combined with the fan to dissipate the heat to the air.
The embodiment of the invention does not specifically limit the object to be radiated, for example, the object to be radiated can be a frequency conversion module of an air conditioner with small size and high heat flux density. When the heat dissipation component provided by the embodiment is adopted to dissipate heat of the frequency conversion module of the air conditioner, compared with the existing aluminum fin radiator, the heat dissipation component can effectively dissipate heat of high-density heat flow, so that the compressor is guaranteed to work under the preset frequency, the compressor is prevented from forcibly reducing the frequency to reduce the heat productivity due to overhigh temperature of the frequency conversion module, and the user experience is further improved. Further, for current refrigerant encircle the aluminium radiator through frequency conversion module, this embodiment will be equipped with the first heat dissipation module of refrigerant pipe in with frequency conversion module direct contact, and then effectively prevented because of the risk that aluminium heating panel and inverter circuit contact surface produce the condensation and then lead to the circuit board short circuit to burn out.

Furthermore, the superconducting heat pipe is similar to a thermal diode, when the temperature of the second heat dissipation module reaches a certain temperature, the superconducting heat pipe starts the phase change heat transfer function, otherwise, the superconducting heat pipe is a common copper pipe. Specifically, the working mode of the heat dissipation member provided in the embodiment of the present invention may be that the second heat dissipation module is in contact with an object to be dissipated, the object to be dissipated serves as a heat source to transfer heat to the second heat dissipation module, the second heat dissipation module receives heat from the object to be dissipated and dissipates the heat, when the temperature of the second heat dissipation module is less than or equal to a preset value, the object to be dissipated is dissipated only by using the second heat dissipation module, at this time, the superconducting heat pipe does not transfer heat, and does not transfer heat of the second heat dissipation module to the first heat dissipation module; when the temperature of the second heat dissipation module is larger than the preset value, the first heat dissipation module and the second heat dissipation module are used for dissipating heat at the same time, at the moment, the superconducting heat pipe plays a heat transfer function and transfers the temperature of the second heat dissipation module to the first heat dissipation module, and the two heat dissipation modules dissipate heat with high heat flow density at the same time, so that the heat dissipation capacity of the heat dissipation component is improved. Specifically, in this embodiment, the object to be radiated may be an air conditioner frequency conversion module with a small size and a large heat flux density; the preset value may be 55 deg.c.

Further, the superconducting heat pipe may further include a third portion connecting the first portion and the second portion. The first part can be one heat conduction section in the superconducting heat pipe or a plurality of heat conduction sections, and the heat conduction sections can not be in contact with each other; similarly, the second portion may be one heat conducting segment of the superconducting heat pipe, or may be a plurality of heat conducting segments, and the plurality of heat conducting segments may not be in contact with each other.

The contact described in this embodiment does not limit the contact manner between the superconducting heat pipe and the first heat dissipation module and the second heat dissipation module, for example, the first portion of the superconducting heat pipe may be disposed on the surface of the first heat dissipation module to transfer heat to the surface of the first heat dissipation module, and further, in order to better exert the heat transfer effect, the first portion of the superconducting heat pipe may be further embedded inside the first heat dissipation module to transfer heat to the inside of the first heat dissipation module; similarly, the second part of the super heat conducting pipe may be disposed on the surface of the second heat dissipation module to transfer heat on the surface of the second heat dissipation module, and further, in order to better exert the heat transfer effect, the second part of the super heat conducting pipe may be further embedded in the second heat dissipation module to transfer heat inside the second heat dissipation module.
The size and shape of the superconducting heat pipe are not particularly limited in the embodiments of the present invention, and for example, the shape of the superconducting heat pipe may be a U shape as shown in fig. 2, or an L shape as shown in fig. 3.
