Description

Technical Field

[0001] This application relates to the technical field of air conditioning equipment, for example, to an outdoor unit of an air conditioner and an air conditioner. Background Art

[0002] In high-temperature situations, the operation of the air conditioner can cause the temperature of the main control board of the outdoor unit to be too high. In order to protect the main board from being damaged, it is easy to trigger the high-temperature protection action. After the high-temperature protection action is triggered, the air conditioner will reduce the operating frequency or even stop, which will greatly reduce the cooling capacity on the indoor side.

[0003] In related technologies, in order to reduce the temperature of the main control board, one way is to use metal fins to connect the heat-generating positions of the outdoor unit main board, transfer the heat to the surface of the metal fins, and then cooperate with the outdoor unit fan for convective heat dissipation. Another way is to introduce the low-temperature refrigerant on the indoor side to circulate and cool the main board module of the outdoor unit.

[0004] In the disclosed implementation process, the following problems exist:

[0005] For the method of using metal fins for heat dissipation, due to the low heat transfer coefficient of the metal fins, the heat dissipation ability is limited. For the method of introducing the low-temperature refrigerant on the indoor side for heat dissipation, it will reduce the cooling effect on the indoor side, and condensation water is likely to be generated on the surface of the pipeline for leading out the low-temperature refrigerant, which will pose a certain safety hazard to the internal circuit of the outdoor unit.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of this application, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

The outdoor unit housing 110 includes an installation cavity. The main control board 120 is disposed in the installation cavity. The semiconductor refrigeration device 130 is disposed in the installation cavity, and the cold end of the semiconductor refrigeration device 130 faces the side of the main control board 120. The semiconductor refrigeration device 130 is used to cool the main control board 120.

The power supply module 140 includes a solar power generation device 142. The solar power generation device 142 is disposed on the outdoor unit housing 110, outside the installation cavity. The solar power generation device 142 is used to convert solar energy into electrical energy.

[0045] In the outdoor air conditioner 1 provided by the embodiments of the present disclosure, the cold end of the semiconductor refrigeration device 130 faces the side of the main control board 120 for cooling the main control board 120. The power supply module 140 is connected to the semiconductor refrigeration device 130 for supplying power to the semiconductor refrigeration device 130. And, the power supply module 140 includes a solar power generation device 142, and the solar power generation device 142 is used to convert solar energy into electrical energy.

[0046] The embodiments of the present disclosure use the semiconductor refrigeration device 130 to cool the main control board 120, improving the heat dissipation efficiency compared with the heat dissipation methods in the related art. And, the semiconductor refrigeration device 130 does not require the use of the low-temperature refrigerant of the refrigeration system of the air conditioner. Compared with the cooling method using the low-temperature refrigerant, the heat dissipation structure is simplified, the pipeline setting is reduced, and the use safety is improved. Further, by setting the power supply device, the solar power generation device 142 is used to supply power to the semiconductor refrigeration device 130, reducing the power consumption. Using the outdoor unit 1 of the present disclosure can extend the usage time of the air conditioner during the high-temperature period in summer and improve the user experience.

[0047] Optionally, in combination with Figure 2 and Figure 3 As shown, the power supply module 140 further includes a storage battery 144. The storage battery 144 is disposed in the outdoor unit housing 110. The access terminal of the storage battery 144 is connected to the solar power generation device 142, and the solar power generation device 142 is used to charge the storage battery 144. The access terminal of the storage battery 144 is connected to the semiconductor refrigeration device 130 to supply power to the semiconductor refrigeration device 130.

[0048] In this embodiment, by providing the storage battery 144, power is supplied to the semiconductor refrigeration device 130. Moreover, the storage battery 144 is connected to the solar power generation device 142. The solar power generation device 142 converts solar energy into electrical energy to charge the storage battery 144, and the storage battery 144 supplies power to the semiconductor refrigeration device 130. In this way, the electricity cost generated by the power consumption of the semiconductor refrigeration device 130 is reduced. And by supplying power to the semiconductor refrigeration device 130 through the storage battery 144, the main control board 120 can be continuously cooled, thereby reducing the temperature of the main control board 120 to extend the service life of the air conditioner, and further enhancing the user experience.

[0049] Optionally, in combination with Figure 3 As shown, the power supply module 140 further includes: a power cord 146 disposed on the storage battery 144 for connecting to an external power source to charge the storage battery 144.

[0050] In this embodiment, the storage battery 144 is further provided with a power cord 146. Through the power cord 146, the storage battery 144 can be charged during the peak and valley periods of night electricity consumption to reduce the overall energy consumption of the machine.

[0051] In some examples, the outdoor unit 1 further includes a control device and a temperature sensor disposed on the outdoor unit 1. The control device is connected to the solar power generation device 142, the storage battery 144, and the semiconductor refrigeration device 130.

[0052] During the day, the solar power generation device 142 is used for power generation, and the storage battery 144 is charged. Through the temperature sensor provided on the outdoor unit 1, the outdoor ambient temperature T is obtained. When T≥T1, the control device controls the storage battery 144 to supply power to the semiconductor refrigeration device 130, and the control device controls the refrigeration gear of the semiconductor refrigeration device 130 to gear 1, where T1 is the first temperature threshold. As the outdoor ambient temperature rises, when T≥T2, the control device controls the refrigeration gear of the semiconductor refrigeration device 130 to gear 2, where T2 is the second temperature threshold, T2>T1, and the refrigeration capacity corresponding to gear 2 is greater than the refrigeration capacity corresponding to gear 1. After entering the night, the outdoor ambient temperature gradually drops. When T<T1, the temperature T0 of the main control board 120 is obtained through the temperature sensor provided on the main control board 120. When T0≥T3, the control device controls the refrigeration gear of the semiconductor refrigeration device 130 to gear 1, and T3 is the third temperature threshold, and T3 can be specifically set according to the safe operating temperature of the electrical components set on the main control board 120. Also, at night, the remaining power of the storage battery 144 is obtained. When the remaining power of the storage battery 144 is less than 80%, the power supply line 146 is connected during the peak-valley electricity period until the storage battery 144 is charged to 100%. Here, the connection of the power supply line 146 can be realized by setting an intelligent switch on the power supply line 146 to be turned on or off through the control device. In this way, by collecting solar power generation with the storage battery 144 and using cheap peak-valley electricity, power supply to the storage battery 144 is achieved, improving the energy-saving effect. Cooperating with the semiconductor refrigeration device 130 to cool down the main control board 120 of the outdoor unit 1 improves the cooling effect on the main control board 120, and extends the service life of the outdoor unit 1, thereby improving indoor comfort and enhancing the user experience.
