[0050] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0052] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0053] Example 1:

[0054] Reference Figure 1 , Figure 2 As shown, the rectifier structure in this embodiment includes a heat dissipation base 1 and a rectifier device 2 mounted on the heat dissipation base 1. The heat dissipation base 1 includes a first surface 101 and a second surface 102 disposed opposite to each other. The bottom surface of the rectifier device 2 is thermally connected to the first surface 101 of the heat dissipation base 1. The heat dissipation base 1 includes a main body 11 and a plurality of extensions 12 extending outward from the main body 11. The first surface 101 and the second surface 102 are horizontal planes. By increasing the surface area of ​​the heat dissipation base 1, the heat from the rectifier device 2 is conducted to the heat dissipation base 1 and exchanged with the air through the heat dissipation base 1, thereby reducing the operating temperature of the rectifier device 2, increasing its durability and stability, extending its service life, improving customer satisfaction, and reducing maintenance costs.

[0055] The rectifier device 2 in this embodiment includes a housing 21 thermally connected to the first surface 101 and at least one rectifier diode 22 disposed within the housing 21. Specifically, refer to... Figure 2 As shown, the rectifier 2 in this embodiment is a bridge rectifier composed of four rectifier diodes 22. Of course, in other embodiments, the rectifier 2 can also be a half-wave rectifier composed of a single rectifier diode 22 connected in series in the AC input circuit, or a center-tapped full-wave rectifier composed of two rectifier diodes 22, or a three-phase rectifier composed of six rectifier diodes 22.

[0056] Preferably, in order to increase the heat dissipation area of ​​the heat dissipation base 1 in contact with the air, refer to Figure 2 , Figure 3 As shown, the extension 12 in this embodiment includes a first heat dissipation surface 121 facing the rectifier 2 and a second heat dissipation surface 122 facing away from the rectifier 2. Both the first heat dissipation surface 121 and the second heat dissipation surface 122 are planar. Of course, in other embodiments, one of the first heat dissipation surface 121 and the second heat dissipation surface 122 may be planar.

[0057] Optionally, refer to Figure 3As shown, the extension 12 in this embodiment also includes a third heat dissipation surface 123 connecting the first heat dissipation surface 121 and the second heat dissipation surface 122. The third heat dissipation surface 123 is a curved surface protruding away from the main body 11. This design increases the heat dissipation area of ​​the heat dissipation base 1 in contact with the air and allows for a smooth transition between the first heat dissipation surface 121 and the second heat dissipation surface 122. Of course, in other embodiments, the third heat dissipation surface 123 can also be a plane, a curved surface recessed towards the main body 11, or a combination of a plane and a curved surface.

[0058] Optionally, refer to Figure 3 As shown, in this embodiment, two adjacent extensions 12 are connected by a fourth heat dissipation surface 124, which is a curved surface recessed towards the main body 11. This design increases the heat dissipation area of ​​the heat dissipation base 1 in contact with the air and allows for a smooth transition between two adjacent extensions 12. Of course, in other embodiments, the third connecting surface can also be a plane, a curved surface protruding away from the main body 11, or a combination of a plane and a curved surface.

[0059] Specifically, refer to Figure 3 As shown, in this embodiment, four extension portions 12 are provided on both sides of the main body 11 that are opposite to each other, and the four extension portions 12 are spaced apart in the direction away from the rectifier 2.

[0060] Reference Figure 3 As shown, since the first heat dissipation surface 121 of the uppermost extension 12 is part of the first surface 101 and the second heat dissipation surface 122 of the lowermost extension 12 is part of the second surface 102, the first heat dissipation surface 121 of the uppermost extension 12 is horizontally arranged and the heat dissipation surface 122 of the lowermost extension 12 is horizontally arranged.

[0061] To increase the heat dissipation area of ​​the heat dissipation base 1 in contact with the air and thus improve heat dissipation, the thickness of the extension 12 gradually decreases at least partially in the direction away from the main body 11. The spacing between two adjacent extensions 12 gradually increases at least partially in the direction away from the main body 11. For example, see reference... Figure 3 As shown, in this embodiment, the thickness of the extension 12 gradually decreases in the direction away from the main body 11, and the distance between two adjacent extensions 12 gradually increases in the direction away from the main body 11.

[0062] To facilitate increasing the heat dissipation area, refer to Figure 3As shown, in this embodiment, multiple extensions 12 are provided on both sides of the main body 11 that are opposite to each other. Compared with a design where only one side wall of the main body 11 has an extension 12, the design of this embodiment further increases the heat dissipation area of ​​the heat dissipation base 1. The extensions 12 on both side walls can be arranged symmetrically or asymmetrically. Compared with an asymmetrical arrangement, the symmetrical arrangement of the heat dissipation base 1 results in a more stable structure and a longer service life.

[0063] Reference Figure 2 As shown, in order to facilitate the transfer of heat from the rectifier 2 to the heat dissipation base 1, in this embodiment, the entire orthographic projection area of ​​the bottom surface of the rectifier 2 onto the first surface 101 is located inside the first surface 101. Of course, in other embodiments, the orthographic projection area of ​​the bottom surface of the rectifier 2 onto the first surface 101 is partially located inside the first surface 101. Compared to the designs of other embodiments, the design of this embodiment increases the effective contact area between the rectifier 2 and the heat dissipation base 1, which is more conducive to heat dissipation.

[0064] Preferably, refer to Figure 2 As shown, in this embodiment, a first thermally conductive adhesive layer 3 is provided between the rectifier device 2 and the heat dissipation base 1. This design fills the gap between the rectifier device 2 and the heat dissipation base 1, increasing the effective contact area between them, reducing thermal resistance, and thus significantly improving heat transfer efficiency. The first thermally conductive adhesive layer 33 can be thermally conductive silicone, thermal paste, or thermal grease, etc., which will not be elaborated here. In this embodiment, the thickness of the first thermally conductive adhesive layer 3 is between 0.1 μm and 50 μm. The thermal conductivity of the first thermally conductive adhesive layer 3 is between 1.0 W / m·K and 5.0 W / m·K. For example, the thickness of the first thermally conductive adhesive layer 3 is 0.1 μm, or 25 μm, or 50 μm. The thermal conductivity of the first thermally conductive adhesive layer 3 is 1.0 W / m·K, or 2 W / m·K, or 5 W / m·K.

[0065] In order to fix the rectifier 2 on the heat sink base 1, refer to Figure 2 As shown, the rectifier structure in this embodiment also includes a first fastener 4, which passes through the rectifier device 2 and is mounted on the main body 11 of the heat sink base 1. Specifically, the main body 11 in this embodiment is provided with a first mounting hole 111, and the rectifier device 2 is provided with a second mounting hole 23 communicating with the first mounting hole 111. The first fastener 4 passes through the first mounting hole 111 and the second mounting hole 23 so that the rectifier device 2 is fixedly mounted on the main body 11 of the heat sink base 1 by the second fastener 7. The first fastener 4 can be a screw, bolt, screw, etc.
