Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0028] As shown in Figure 1 In a first aspect, embodiments of the present application provide a heat dissipation structure 1 adapted to dissipate heat from a heat source 3 in an air conditioner 100, which has the advantages of simple structure, good heat dissipation effect, low energy consumption, low noise, etc., and can better meet the use needs. Here, the heat source 3 in the air conditioner 100 can include, for example, an electric control box and heat generating components therein, a compressor, and other heat generating components that generate a large amount of heat when operating.

[0029] Here, the heat dissipation structure 1 includes the heat pipe 10 and the ultrasonic wave generating device 20. The heat pipe 10 is made of a heat-conductive material and thus has good heat conduction performance; one end of the heat pipe 10 is connected to the heat source 3, and can directly absorb heat from the heat source 3 to cool the heat source 3. The ultrasonic wave generating device 20 is arranged in the heat pipe 10 near the one end of the heat pipe 10 close to the heat source 3, and is configured to generate ultrasonic waves propagating along the heat pipe 10 and vibrate the heat pipe 10. On the one hand, the ultrasonic wave generating device 20 generates ultrasonic waves in a vibration mode, which can transmit the vibration to the heat pipe 10, so as to make the heat pipe 10 at least slightly vibrate, convert the heat energy absorbed from the heat source 3 into mechanical energy for consumption, and increase the heat conduction rate in the heat pipe 10, thereby enhancing the heat dissipation effect of the heat pipe 10; on the other hand, the ultrasonic waves can forcibly accelerate the directional flow of air along the heat pipe 10, so that the air quickly flows from the one end of the heat pipe 10 close to the heat source 3 to the other end of the heat pipe 10 away from the heat source 3, and then is discharged from the heat pipe 10, thereby achieving a better air flow heat dissipation effect; on the third hand, the vibration of the heat pipe 10 is relatively slight, and the ultrasonic waves are within the audible range of human ears, so that the noise of the above heat dissipation structure 1 is relatively small.

[0030] The heat dissipation structure 1 provided by the embodiment of the present application can achieve a better heat dissipation effect by arranging the heat pipe 10 and the ultrasonic wave generating device 20 which are relatively simple in structure and low in energy consumption, and the vibration of the heat pipe 10 is relatively slight and the ultrasonic waves are within the audible range of human ears, so that the noise is relatively small. Compared with the related art, the heat dissipation structure 1 provided by the embodiment of the present application has the advantages of simple structure, good heat dissipation effect, low energy consumption, and small noise, and can better meet the use needs.

[0031] The material of the heat pipe 10 can be determined according to actual needs, and can be, for example, a metal material, a heat-conductive plastic, or the like, which is not limited in the embodiment of the present application. In some embodiments, the heat pipe 10 can be an aluminum pipe, which has good heat conduction performance and vibration performance and is conducive to rapid heat dissipation. In some embodiments, the inner wall of the aluminum pipe can be arranged as a smooth surface to facilitate the rapid propagation of ultrasonic waves along the aluminum pipe.

[0032] In some embodiments, the ultrasonic wave generating device 20 can include an ultrasonic wave controller 21 and an ultrasonic wave transducer 22 connected in conduction, and the ultrasonic wave controller 21 is configured to drive the ultrasonic wave transducer 22 to generate ultrasonic waves. In other words, the ultrasonic wave controller 21 is configured to generate a driving electric signal, and the ultrasonic wave transducer 22 converts electrical energy into mechanical vibration based on the driving electric signal, and then generates an ultrasonic wave signal through the mechanical vibration.

[0033] In some examples, the heat dissipation structure 1 can include a temperature sensor 40 configured to detect the current temperature of the heat source 3. The temperature sensor 40 is arranged at one end of the heat conduction pipe 10 close to the heat source 3, or the temperature sensor 40 is arranged on the heat source 3. The ultrasonic controller 21 and the temperature sensor 40 are electrically connected, and the ultrasonic controller 21 is configured to control the frequency and / or power of the ultrasonic transducer 22 according to the temperature information measured by the temperature sensor 40, so that the frequency and / or power of the ultrasonic transducer 22 matches the heat dissipation demand of the heat source 3.

[0034] In some examples, the ultrasonic transducer 22 can be arranged on the inner wall of the heat conduction pipe 10 to generate ultrasonic waves propagating along the heat conduction pipe 10 and vibrate the heat conduction pipe 10. Here, the ultrasonic heat exchanger is in contact with the inner wall of the heat conduction pipe 10, so as to transmit the vibration generated by the ultrasonic transducer 22 to the heat conduction pipe 10, thereby causing the heat conduction pipe 10 to vibrate at least slightly.

[0035] In some examples, a plurality of heat dissipation fins 11 can be arranged on the outer peripheral wall of the heat conduction pipe 10. The plurality of heat dissipation fins 11 are arranged at intervals, and the ultrasonic transducer 22 is further configured to vibrate the heat dissipation fins 11. By arranging a plurality of heat dissipation fins 11, on the one hand, the contact heat exchange area between the heat conduction pipe 10 and the air can be increased, and on the other hand, a large part of the heat energy can be converted into mechanical energy for consumption through the vibration of the heat dissipation fins 11, thereby comprehensively improving the heat dissipation effect of the heat conduction pipe 10 through the above two aspects.

[0036] In some examples, the heat dissipation structure 1 can include a heat conduction damping layer 30 arranged between the heat source 3 and the heat conduction pipe 10. Here, the heat conduction damping layer 30 has a flexible structure, which can be in contact with the surface of the heat source 3 and the end of the heat conduction pipe 10, respectively, thereby increasing the heat conduction area between the surface of the heat source 3 and the end of the heat conduction pipe 10, and on the other hand, can buffer and absorb the vibration of the heat conduction pipe 10, avoid the vibration being transmitted to the heat source 3 to cause the heat source 3 to be damaged and work unstably, and consume and absorb the mechanical vibration energy of the heat conduction pipe 10 to improve the heat dissipation effect.

[0037] The structure of the heat conduction damping layer 30 can be determined according to actual needs, which is not limited in the embodiments of the present application. In some examples, the heat conduction damping layer 30 can include a first heat conduction adhesive layer 31, an elastic buffer layer 32 and a second heat conduction adhesive layer 33 arranged in sequence. The first heat conduction adhesive layer 31 is bonded and fixed to the heat source 3, and the second heat conduction adhesive layer 33 is bonded and fixed to the end of the heat conduction pipe 10 close to the heat source 3. In this way, the first heat conduction adhesive layer 31 and the second heat conduction adhesive layer 33 can be used to realize reliable bonding and fixation between the heat source 3 and the heat conduction pipe 10, avoid accidental separation of the heat source 3 and the heat conduction pipe 10, and ensure the heat dissipation effect of the heat conduction pipe 10 on the heat source 3.

[0038] In some embodiments, the air conditioner 100 can include an outdoor fan 2, and the opening of the thermally conductive pipe 10 away from the heat source 3 is arranged towards the outdoor fan 2. In this way, the outdoor fan 2 can be used to further promote the directional flow of air along the thermally conductive pipe 10, and then the air in the thermally conductive pipe 10 is discharged to the external environment, realizing the effect of rapid air cooling heat dissipation. In addition, the above-mentioned heat dissipation structure 1 uses the negative pressure of the outdoor fan 2 to realize forced convection, without the need to additionally set up an independent driven fan, which can save the required devices and reduce the structural cost.

[0039] As shown in FIG. 1, in the first aspect, the embodiments of the present application provide a heat dissipation structure 1. The heat dissipation structure 1 includes a heat source 3, a thermally conductive pipe 10, an ultrasonic wave generating device 20, and a temperature sensor 40. Figure 2 As shown in FIG. 2, in the second aspect, the embodiments of the present application provide a heat dissipation control method for controlling the heat dissipation structure 1 provided by any of the above embodiments. The heat dissipation control method includes S10-S20.

[0040] S10: Determine whether the difference between the current temperature of the heat source 3 and the target temperature is greater than a first threshold temperature difference. Here, the current temperature of the heat source 3 can be measured in real time by the temperature sensor 40. The target temperature of the heat source 3 can be the ideal temperature of the heat source 3 when it is running, which can be set in advance; at this target temperature, the running state of the heat source 3 is better.

[0041] S20: In response to determining that the difference between the current temperature of the heat source 3 and the target temperature is greater than the first threshold temperature difference, increase the frequency and / or power of the ultrasonic wave generating device 20. Here, the first threshold temperature can be set in the control system of the air conditioner 100, which is used to judge the high and low of the current temperature of the heat source 3 and the size of the heat dissipation demand of the heat source 3.

[0042] When it is determined that the difference between the current temperature of the heat source 3 and the target temperature is greater than the first threshold temperature difference, it indicates that the current temperature of the heat source 3 is higher and significantly higher than the target temperature of the heat source 3, and the heat dissipation demand of the heat source 3 is larger. At this time, the frequency and / or power of the ultrasonic wave generating device 20, for example, the ultrasonic wave transducer 22 therein, can be controlled to increase, so as to improve the heat dissipation performance of the thermally conductive pipe 10, thereby matching the heat dissipation demand of the heat source 3, so that the current temperature of the heat source 3 can be quickly reduced to the target temperature.

[0043] The heat dissipation control method provided by the embodiments of the present application can feedback and adjust the frequency and / or power of the ultrasonic wave generating device 20 according to the relationship between the current temperature of the heat source 3 and the target temperature, thereby matching the heat dissipation demand of the heat source 3, and realizing a better heat dissipation effect.

[0044] As shown in FIG. 2, in some embodiments, S20 can include S21-S23. Figure 3

[0045] ​S21: in response to determining that the difference between the current temperature of the heat source 3 and the target temperature is greater than the first threshold temperature difference, determining whether the difference between the current temperature of the heat source 3 and the current temperature of the heat pipe 10 is greater than a second threshold temperature difference. Here, the second threshold temperature can be pre-set in the control system of the air conditioner 100 for judging the degree of deviation between the current temperature of the heat source 3 and the current temperature of the heat pipe 10, and thus reflecting the level of the current heat dissipation effect of the heat pipe 10.

[0046] S22: in response to determining that the difference between the current temperature of the heat source 3 and the current temperature of the heat pipe 10 is greater than the second threshold temperature difference, controlling the frequency and / or power of the ultrasonic wave generating device 20 to immediately increase by a first increase amplitude, or gradually increase at a first increase rate.

[0047] When it is determined that the difference between the current temperature of the heat source 3 and the current temperature of the heat pipe 10 is greater than the second threshold temperature difference, it indicates that the current temperature of the heat source 3 is relatively high and significantly higher than the current temperature of the heat pipe 10, and the heat dissipation capacity of the heat pipe 10 has not reached saturation and has a large heat dissipation potential. At this time, the frequency and / or power of the ultrasonic wave generating device 20 can be controlled to immediately increase by a small first increase amplitude for one-time small increase, or gradually increase at a small first increase rate, avoiding the rapid and large increase of the frequency and / or power of the ultrasonic wave generating device 20 to cause energy waste, and achieving a better energy saving effect.

[0048] Here, when the frequency of the ultrasonic wave generating device 20 is controlled to immediately increase by the first increase amplitude, the first increase amplitude can be a frequency increase amplitude; when the power of the ultrasonic wave generating device 20 is controlled to immediately increase by the first increase amplitude, the first increase amplitude can be a power increase amplitude. Similarly, when the frequency of the ultrasonic wave generating device 20 is controlled to gradually increase at the first increase rate, the first increase rate can be a frequency increase rate; when the power of the ultrasonic wave generating device 20 is controlled to gradually increase at the first increase rate, the first increase rate can be a power increase rate.

[0049] S23: in response to determining that the difference between the current temperature of the heat source 3 and the current temperature of the heat pipe 10 is less than or equal to the second threshold temperature difference, controlling the frequency and / or power of the ultrasonic wave generating device 20 to immediately increase by a second increase amplitude, or gradually increase at a second increase rate. Here, the second increase amplitude is greater than the first increase amplitude, and the second increase rate is greater than the first increase rate.

[0050] When the difference between the current temperature of the heat source 3 and the current temperature of the heat pipe 10 is determined to be less than or equal to the second threshold temperature difference, it indicates that the current temperature of the heat source 3 is higher than the current temperature of the heat pipe 10, but the current temperature of the heat source 3 is higher by a smaller amplitude, the heat dissipation capacity of the heat pipe 10 tends to be saturated, and the heat dissipation potential is small. At this time, the frequency and / or power of the ultrasonic wave generating device 20 can be controlled to immediately increase by a small amplitude once in a larger second rising amplitude, or the frequency and / or power of the ultrasonic wave generating device 20 can be controlled to gradually increase at a faster second rising rate, so as to quickly match the heat dissipation demand of the heat source 3, so that the current temperature of the heat source 3 can be quickly reduced to the target temperature.

[0051] As shown in Figure 4 the third aspect, the embodiments of the present application provide an air conditioner 100, which comprises a heat source 3 and the heat dissipation structure 1 provided by any one of the above embodiments. The type of the air conditioner 100 can be determined according to actual needs, and types such as wall-mounted air conditioners, cabinet air conditioners, window air conditioners, etc. can be used, and the embodiments of the present application do not limit this. The air conditioner 100 provided by the embodiments of the present application has the heat dissipation structure 1 described above, has the advantages of simple structure, better heat dissipation effect, lower energy consumption, and smaller noise, etc., and can better meet the use needs.

[0052] In some embodiments, the air conditioner 100 can comprise an outdoor fan 2, and an end of the heat pipe 10 away from the heat source 3 is arranged to open towards the outdoor fan 2. In this way, the outdoor fan 2 can be used to further promote the directional flow of air along the heat pipe 10, and then the air in the heat pipe 10 is discharged to the external environment, achieving the effect of rapid air cooling and heat dissipation. In addition, the above heat dissipation structure 1 uses the negative pressure of the outdoor fan 2 to achieve forced convection, so that the air conditioner 100 does not need to additionally set up an independent driven fan, and the required devices can be saved, and the structural cost is reduced.
