[0026] See also Figures 1 to 6 As shown, according to an embodiment of the present application, a heat sink includes a first heat sink 1, a second heat sink 3 and a connecting portion 2, wherein the connecting portion 2 includes a first section and a second section, wherein the first section is arranged on the first heat sink 1, and the second section is arranged on the second heat sink 3, and the connecting portion 2 can be bent so that the first heat sink 1 and the second heat sink 3 are arranged at an angle. By providing the connecting portion 2, and the connecting portion 2 can be bent, the first heat sink 1 can be rotated, and the position and orientation of the first heat sink 1 can be adjusted so that the first heat sink 1 is parallel to the wind direction of the heat dissipation wind, which can effectively increase the contact area between the heat dissipation wind and the heat sink, improve the heat dissipation efficiency of the heat sink, and ensure the service life of the power device.

[0027] Further, as an implementation mode, the connection part 2 may be a metal sheet with good thermal conductivity, that is, the first heat dissipation part 1 and the second heat dissipation part 3 are connected via the metal sheet.

[0028] The second heat dissipation part 3 includes a second fin and a substrate. The second fin is arranged on the substrate, and the substrate is arranged on the mounting carrier.

[0029] As another embodiment, the substrate of the second heat dissipation part 3 extends in a direction away from the mounting carrier and can be bent to serve as the connecting part 2 , that is, the first heat dissipation part 1 is disposed on the extended substrate of the second heat dissipation part 3 .

[0030] Furthermore, the first heat dissipation part 1, the second heat dissipation part 3 and the connecting part 2 are made of heat-conducting materials. The heat of the power element is transferred to the connecting part 2 through the second heat dissipation part 3, and then transferred to the first heat dissipation part 1. At the same time, the second heat dissipation part 3, the connecting part 2 and the first heat dissipation part 1 can also play a heat dissipation role.

[0031] The second heat dissipation part 3 is arranged on the mounting carrier, the first heat dissipation part 1 includes a first fin 11, and the connecting part 2 is bent so that the plane where the first fin 11 is located is on the flow path of the heat dissipation air. By rotating the first fin 11, the contact area between the heat dissipation air and the heat sink can be effectively increased, the heat dissipation efficiency of the heat sink can be improved, and the service life of the power device can be guaranteed.

[0032] Furthermore, in this embodiment, the power element to be cooled is arranged on the second cooling portion 3 .

[0033] Furthermore, the plane where the first fins 11 are located is on the flow path of the heat dissipation air, and the plane where the first fins 11 are located is parallel to the wind direction of the heat dissipation air.

[0034] The second heat dissipation portion 3 includes a first end and a second end opposite to each other, and the first end is arranged on the mounting carrier. When the connecting portion 2 is not bent, the first heat dissipation portion 1 is parallel to the second heat dissipation portion 3, and the first heat dissipation portion 1 is arranged opposite to the second end, thereby increasing the distance between the second heat dissipation portion 3 and the mounting carrier, thereby facilitating the heat dissipation of the second heat dissipation portion 3.

[0035] Further, such as Figure 1 As shown, in this embodiment, the first end is the bottom end of the second heat dissipation portion 3 , and the second end is the top end of the second heat dissipation portion 3 . When the connecting portion 2 is not bent, the first heat dissipation portion 1 is located above the second heat dissipation portion 3 .

[0036] The connecting portion 2 can be bent 90° so that the angle between the first heat dissipation portion 1 and the second heat dissipation portion 3 is a right angle. In the prior art, the flow direction of the heat dissipation air is usually perpendicular to the fins of the radiator. In this embodiment, the connecting portion 2 can be bent 90°, which can adapt to the existing heat dissipation fan and heat dissipation air duct, etc., thereby improving the applicability of the radiator.

[0037] A slideway 21 is provided on the connecting portion 2 , and the first heat dissipating portion 1 is slidably provided on the slideway 21 , which can further increase the contact area between the first heat dissipating portion 1 and the heat dissipating air.

[0038] Furthermore, when the connecting portion 2 is not bent, sliding the first heat dissipation portion 1 in a direction away from the mounting carrier can effectively increase the contact area between the first heat dissipation portion 1 and the heat dissipation air, thereby improving the heat exchange capacity.

[0039] Furthermore, when the connecting portion 2 is bent, the first heat dissipation portion 1 can slide on the slideway 21 so that the first heat dissipation portion 1 and the second heat dissipation portion 3 form a T-shaped structure, thereby improving the stability of the radiator and preventing the radiator from being damaged due to uneven force.

[0040] like Figure 5 As shown, when the connecting portion 2 is bent 90°, the first heat dissipation portion 1 slides to the right, so that the first heat dissipation portion 1 and the second heat dissipation portion 3 form a roughly T-shaped structure, so that the center of gravity of the first heat dissipation portion 1 falls on the top of the second heat dissipation portion 3, making the overall structure and force more stable.

[0041] The first heat dissipation part 1 also includes a first base plate 12, and the first fin 11 is arranged on the first base plate 12. The radiator also includes a sliding member 4, one end of the sliding member 4 is fixed on the first base plate 12, and the other end of the sliding member 4 passes through the slide 21, so that the first heat dissipation part 1 is slidably arranged on the slide 21 through the sliding member 4. By setting the sliding member 4, the first heat dissipation part 1 can slide more smoothly in the slide 21.

[0042] Furthermore, the first fin 11 is arranged on one side of the first bottom plate 12 , and the sliding member 4 is arranged on the other side of the first bottom plate 12 .

[0043] Furthermore, in this embodiment, the sliding member 4 is a screw, the slideway 21 is a slide groove, and the screw passes through the slide groove and is fixed on the first bottom plate 12 .

[0044] Furthermore, the diameter of the screw rod of the screw is equal to the width of the slideway 21, so the screw can slide stably in the slideway.

[0045] One end of the sliding member 4 away from the first bottom plate 12 is arranged on a limiting member to limit the sliding member 4 on the slideway 21 to prevent the sliding member 4 from being separated from the slideway 21 .

[0046] Furthermore, in this embodiment, the limiting member is the head of the screw, the tail of the screw is fixed to the first bottom plate 12 , and the diameter of the head of the screw is larger than the width of the slideway 21 to prevent the screw from falling out of the slideway 21 .

[0047] A first locking hole and a second locking hole are provided on the slide 21, and the sliding member 4 can be locked in the first locking hole or the second locking hole. By providing the first locking hole and the second locking hole, the sliding member 4 is locked when it slides to the first locking hole and the second locking hole, thereby ensuring a stable connection between the first heat dissipation part 1 and the second heat dissipation part 3.

[0048] Furthermore, the first locking hole is located at one end of the slide 21, and the second locking hole is located at the other end of the slide 21. When the sliding member 4, i.e., the screw, slides to the first locking hole or the second locking hole, the screw is tightened to lock the first heat dissipation part 1 and the second heat dissipation part 3 with each other.

[0049] The first heat dissipation part 1 can rotate in the slideway 21 with the sliding member 4 as the axis. When the mainboard direction is rotated in different unit layouts, the windward angle can be adjusted by rotating the fin angle to match different ventilation duct directions.

[0050] Furthermore, the first heat dissipation part 1 can rotate in the plane with the sliding part 4 as the axis. That is, in this embodiment, the first heat dissipation part 1 is perpendicular to the second heat dissipation part 3, the second heat dissipation part 3 is in the vertical plane, and the first heat dissipation part 1 is in the horizontal plane. The first heat dissipation part 1 can rotate in the horizontal plane with the sliding part 4 as the axis to adapt to the wind direction of the heat dissipation wind.

[0051] Furthermore, when multiple power devices are arranged compactly or side by side, the interference between the fins can be prevented by deflecting the angle of the upper fins in the same direction by a small angle.

[0052] Another aspect of the present embodiment provides an air conditioner including the above-mentioned radiator.

[0053] A heat sink provided in an embodiment of the present invention can effectively increase the contact area between the heat dissipation wind and the heat sink, improve the heat dissipation efficiency of the heat sink, and ensure the service life of the power device.
