[0024] For detailed implementation method one, please refer to... Figure 1 , Figure 2 and Figure 3A power converter structure includes a frame 1, a winding 2, and a magnetic core 3. The frame 1 is hollow and accommodates the winding 2 and the magnetic core 3. The frame 1 can be composed of a frame portion 10 and a support portion 11. The frame portion 10 has a receiving space 100 for the winding 2 to be housed within it, and a through hole 101 is provided above the frame portion 10, communicating with the receiving space 100. The support portion 11 is connected to the lower part of the frame portion 10 and can be integrally formed, with the frame portion 10 and the support portion 11 protruding outward from below the frame portion 10. The winding 2 is housed within the receiving space 100 of the frame 1 and is located within the frame portion 10 below the through hole 101. Furthermore, the winding 2 can be composed of a wire frame 20 disposed within the frame 10, and one or more sets of windings 21 wound around the wire frame 20. The magnetic core 3 is spaced apart from the winding 2 and can be made of ferrite or stacked silicon steel sheets. The magnetic core 3 can be configured and surround the receiving space 100 of the frame 1, for example, by being sandwiched between two U-shaped magnets from both sides of the frame 10; of course, it can also be configured in the receiving space 100 and spaced apart from the winding. This invention mainly involves adding an air guide shroud 12 to the aforementioned frame 1. The air guide shroud 12 has an air guide plate 120 and two side plates 121 extending from both sides of the air guide plate 120. An air inlet 122 is formed at one end between the air guide plate 120 and the two side plates 121, allowing the air guide shroud 12 to cover the through hole 101 at the top of the frame 1, with its air inlet 122 facing a location such as a fan (not shown). Figure 3 As shown, external airflow can pass through the air inlet 122 and be guided by the air guide shroud 12 to the through hole 101 and enter the interior of the frame 1 to provide heat dissipation or cooling for the winding 2. Simultaneously, the airflow entering the frame 1 can also be discharged through the gap between the frame 11 and the circuit board 4. Furthermore, the air guide shroud 12 can be provided with a rear plate 123 at the other end between the air guide plate 120 and the two side plates 121 to restrict the incoming airflow from being guided to the through hole 101 and entering the interior of the frame 1 to cool the winding. Additionally, as... Figure 4 As shown, in the second embodiment of this invention, the air guide shroud 12 may also be provided with an exhaust port 123a on the rear plate 123, or the exhaust port 123a may be formed directly at the other end between the air guide plate 120 and the two side plates 121, so that excessive airflow can be discharged through the exhaust port 123a.
[0025] Also, such as Figure 5 As shown, the air guide plate 120 of the aforementioned air guide shroud 12 can also be in a curved shape; and as described above Figure 3 or Figure 4 In one embodiment, the air guide plate 120 may be inclined.
[0026] Furthermore, such as Figure 6 As shown, the aforementioned air guide shroud 12 can also have an expanded guide portion 121a added outward at the air inlet 122, so that the external airflow can be more effectively concentrated towards the air inlet 122 and enter the frame 1 to cool the winding. Therefore, by the above-described structure, the power converter structure of this invention can be obtained.
