[0041] Combination Figures 1 to 6 As shown, an embodiment of the present disclosure provides a self-cleaning heat exchange component 10. The self-cleaning heat exchange component 10 includes a first heat exchange tube 11, a second heat exchange tube 12, a plurality of heat sinks 13 and a ventilation device 14. The second heat exchange tube 12 is arranged opposite to the first heat exchange tube 11, and the second heat exchange tube 12 is arranged at intervals from the first heat exchange tube 11. A plurality of heat sinks 13 are staggered in the first heat exchange tube 11 and the second heat exchange tube 12. The ventilation device 14 and the second heat exchange tube 12 are respectively located on opposite sides of the first heat exchange tube 11. Among them, the ventilation device 14 can switch between a suction state and a blowing state to clean the heat sink 13.
[0042] In this embodiment, the heat exchange efficiency can be improved by arranging the second heat exchange tube 12 opposite to the first heat exchange tube 11 and the second heat exchange tube 12 and the first heat exchange tube 11 are arranged at intervals. Specifically, the second heat exchange tube 12 and the first heat exchange tube 11 are arranged opposite to each other and at intervals, so that the interval between the second heat exchange tube 12 and the first heat exchange tube 11 can provide space for the extension of the heat sink 13, thereby improving the heat exchange efficiency.
[0043] In this embodiment, a plurality of heat sinks 13 are staggeredly arranged on the first heat exchange tube 11 and the second heat exchange tube 12, which can not only improve the heat exchange efficiency, but also facilitate the cleaning of blockages such as fluff on the heat sink 13, thereby improving the cleaning effect. Specifically, a plurality of heat sinks 13 are staggeredly arranged on the first heat exchange tube 11 and the second heat exchange tube 12, that is, the heat sinks 13 located on the first heat exchange tube 11 and the heat sinks 13 located on the second heat exchange tube 12 are staggered, thereby improving the smoothness of ventilation, facilitating the ventilation airflow to bring blockages such as fluff out of the heat sink 13, thereby improving the cleaning effect.
[0044] In actual application, the overall structure formed by the first heat exchange tube 11, the second heat exchange tube 12 and the plurality of heat sinks 13 is equivalent to a condenser. Refrigerant can flow through the first heat exchange tube 11 and the second heat exchange tube 12. The first heat exchange tube 11 and the second heat exchange tube 12 are arranged opposite to each other and at intervals, and the plurality of heat sinks 13 are staggered on the first heat exchange tube 11 and the second heat exchange tube 12, so that the heat exchange efficiency can be improved.
[0045] In this embodiment, the ventilation device 14 and the second heat exchange tube 12 are respectively located on opposite sides of the first heat exchange tube 11, so that the heat sink 13 located in the first heat exchange tube 11 and the heat sink 13 located in the second heat exchange tube 12 can be cleaned simultaneously by the ventilation device 14, and the cleaning structure is simple, and the cost is reduced. The ventilation device 14 can switch between the suction state and the blowing state, which can improve the cleaning effect of the heat sink 13 and the heat exchange efficiency, and has a simple structure and reduces the cost.
[0046] Exemplarily, when the ventilation device 14 is in the suction state, the airflow generated by the ventilation device 14 can drive the lint and other blockages on the heat sink 13 to move toward the ventilation device 14 to clean the heat sink 13. When the ventilation device 14 is in the blowing state, the airflow generated by the ventilation device 14 can drive the lint and other blockages on the heat sink 13 to move away from the ventilation device 14 to clean the heat sink 13. By switching the ventilation device 14 between the suction state and the blowing state, the airflow acts back and forth on the lint and other blockages on the heat sink 13 to remove the lint and other blockages stuck on the heat sink 13, thereby improving the cleaning effect.

[0048] In this embodiment, a plurality of first flat tubes 111 are arranged at intervals, and the plurality of first flat tubes 111 are sequentially connected in series, so that the first heat exchange tube 11 is serpentine in shape as a whole, saving installation space. The interval between two adjacent first flat tubes 111 forms a first installation space 113, which provides space for the installation of the heat sink 13.
[0049] In this embodiment, a plurality of second flat tubes 121 are arranged at intervals, and a plurality of second flat tubes 121 are sequentially connected in series, so that the second heat exchange tube 12 is serpentine in shape as a whole, saving installation space. The interval between two adjacent second flat tubes 121 forms a second installation space 123, which provides space for the installation of the heat sink 13.
[0050] In this embodiment, the first installation space 113 and the second installation space 123 can both be provided with heat sinks 13, which facilitates the arrangement of the heat sinks 13. In actual application, part of the first installation space 113 of the first heat exchange tube 11 is provided with heat sinks 13, and part of the second installation space 123 of the second heat exchange tube 12 is provided with heat sinks 13, so that the heat sinks 13 located in the first heat exchange tube 11 and the heat sinks 13 located in the second heat exchange tube 12 are arranged alternately, that is, a plurality of heat sinks 13 are alternately arranged in the first heat exchange tube 11 and the second heat exchange tube 12, which facilitates cleaning and can improve the heat dissipation effect.
[0051] Combination Figure 4 As shown, in some embodiments, the first heat exchange tube 11 further includes a first elbow 112. Both ends of the first elbow 112 are respectively connected to two adjacent first flat tubes 111, so that the two adjacent first flat tubes 111 are connected in series. The second heat exchange tube 12 further includes a second elbow 122. Both ends of the second elbow 122 are respectively connected to two adjacent second flat tubes 121, so that the two adjacent second flat tubes 121 are connected in series.
[0052] In this embodiment, both ends of the first curved pipe 112 are respectively connected to two adjacent first flat tubes 111 to realize the series connection of the two adjacent first flat tubes 111. In practical application, a plurality of first curved pipes 112 are provided. Through the plurality of first curved pipes 112, the plurality of first flat tubes 111 are sequentially connected in series to form a first heat exchange tube 11 with a serpentine structure.
[0053] In this embodiment, the two ends of the second curved pipe 122 are respectively connected to two adjacent second flat tubes 121 to realize the series connection of the two adjacent second flat tubes 121. In actual application, a plurality of second curved pipes 122 are provided. Through the plurality of second curved pipes 122, the plurality of second flat tubes 121 are sequentially connected in series to form a second heat exchange tube 12 with a serpentine structure.
[0054] Combination Figure 4 As shown, optionally, the first heat exchange tube 11 and the second heat exchange tube 12 have the same structure.
[0055] Combination Figures 1 to 3 As shown, in some embodiments, the heat sink 13 located at the first heat exchange tube 11 extends in the direction of the second heat exchange tube 12, and the heat sink 13 extends out of the first heat exchange tube 11. The heat sink 13 located at the second heat exchange tube 12 extends in the direction of the first heat exchange tube 11, and the heat sink 13 extends out of the second heat exchange tube 12. Along the direction from the first heat exchange tube 11 to the second heat exchange tube 12, there is a gap between the heat sink 13 located at the first heat exchange tube 11 and the heat sink 13 located at the second heat exchange tube 12.
[0056] In this embodiment, the heat sink 13 located at the first heat exchange tube 11 extends in the direction of the second heat exchange tube 12, and the heat sink 13 extends out of the first heat exchange tube 11, that is, the heat sink 13 located at the first heat exchange tube 11 extends relative to the first heat exchange tube 11 to the interval between the first heat exchange tube 11 and the second heat exchange tube 12 to improve the heat exchange effect.
[0057] In this embodiment, the heat sink 13 located at the second heat exchange tube 12 extends in the direction of the first heat exchange tube 11, and the heat sink 13 extends out of the second heat exchange tube 12. That is, the heat sink 13 located at the second heat exchange tube 12 extends relative to the second heat exchange tube 12 to the gap between the first heat exchange tube 11 and the second heat exchange tube 12 to improve the heat exchange effect.
[0058] In this embodiment, along the direction from the first heat exchange tube 11 to the second heat exchange tube 12, there is a gap (such as Figure 2 L in the figure) allows the lint and other obstructions on the heat sink 13 to fall from the gap L, shortening the moving path of the lint and other obstructions between the first heat exchange tube 11 and the second heat exchange tube 12, thereby improving the cleaning effect.
[0059] For example, when the ventilation device 14 is in the suction state, the lint and other obstructions on the heat sink 13 of the first heat exchange tube 11 can leave the heat sink 13 under the influence of the ventilation airflow, and fall from the side of the first heat exchange tube 11 away from the second heat exchange tube 12, thereby cleaning the heat sink 13. When the ventilation device 14 is in the suction state, the lint and other obstructions on the heat sink 13 of the second heat exchange tube 12 can leave the heat sink 13 under the influence of the ventilation airflow, and fall from the gap L, thereby cleaning the heat sink 13.
[0060] For example, when the ventilation device 14 is in the blowing state, the lint and other obstructions on the heat sink 13 of the first heat exchange tube 11 can leave the heat sink 13 under the influence of the ventilation airflow and fall from the gap L, thereby cleaning the heat sink 13. When the ventilation device 14 is in the blowing state, the lint and other obstructions on the heat sink 13 of the second heat exchange tube 12 can leave the heat sink 13 under the influence of the ventilation airflow and fall from the side of the second heat exchange tube 12 away from the first heat exchange tube 11, thereby cleaning the heat sink 13.

The heat sink 131 is vertically disposed relative to the first flat tube 111, which can be understood as the heat sink 131 being perpendicular to the two first flat tubes 111 adjacent to the heat sink 131.
[0063] In this embodiment, for the heat sink 13 disposed on the second heat exchange tube 12, the plurality of heat sinks 131 of the heat sink 13 are all disposed in the second installation space 123, and the heat sink 131 is vertically disposed or tilted relative to the second flat tube 121 to achieve a heat dissipation effect.

[0066] In this embodiment, for the heat sink 13 disposed on the first heat exchange tube 11, when the heat sink 131 is disposed obliquely relative to the first flat tube 111, a plurality of heat sinks 131 are sequentially connected end to end to form a whole, which facilitates the installation of the heat sink 131 and improves work efficiency. In addition, it is convenient for the airflow of the ventilation device 14 to remove blockages such as lint from the heat sink 131.
[0067] In this embodiment, for the heat sink 13 disposed on the second heat exchange tube 12, when the heat sink 131 is disposed obliquely relative to the second flat tube 121, a plurality of heat sinks 131 are sequentially connected end to end to form a whole, which facilitates the installation of the heat sink 131 and improves work efficiency.

In addition, the support frame 15 can make the positions of the first heat exchange tube 11, the second heat exchange tube 12 and the plurality of heat sinks 13 correspond to the air outlet of the fan, thereby improving the cleaning effect of the fan on the heat sink 13 when the fan is in the suction state or the blowing state.
