Description

Technical Field

[0001] This utility model relates to a transformer, and more particularly to a slotted transformer structure that provides heat dissipation and air collection. Background Technology

[0002] Existing slotted transformers (also known as split transformers) have the primary winding and secondary winding wound in different winding slots, and energy conversion is achieved through the magnetic flux conduction of the iron core.

[0003] However, while this structure can reduce the risk of leakage flux and insulation between windings, the primary and secondary windings are configured in different slots, and the slots are mostly separated by iron cores or insulators, which reduces the heat conduction efficiency between the windings. When the transformer operates for a long time, the primary winding is prone to heating up due to the input voltage and current. This heat is not easily dissipated effectively through the iron core or insulating components, resulting in excessively high local temperature rise. This not only affects the efficiency and stability of the transformer, but may also accelerate the aging of the winding insulation materials.

[0004] In view of this, the creator has devoted himself to research and application of theoretical principles in order to improve and solve the above-mentioned deficiencies, and finally proposed a design that is reasonable and effective in improving the above-mentioned deficiencies. Summary of the Invention

[0005] The purpose of this utility model is to provide a slotted transformer structure with air collection, which is achieved by adding an air collection shroud to allow external airflow or airflow to enter, thereby providing effects such as heat dissipation and cooling of the primary winding.

[0006] To achieve the above-mentioned main objectives, a slotted transformer structure with air collection is provided, including: a winding frame having a base and a winding part disposed on the base, wherein the winding part is provided with a first winding slot and a second winding slot; The first magnetic core is disposed on the winding frame relative to the first winding slot; The second magnetic core is disposed on the winding frame relative to the second winding slot; and The air collecting hood has at least an expansion portion, and the expansion portion is located on either side of the first winding groove and is in an outward expansion shape.

[0007] Furthermore, the winding portion is vertically arranged on the foot, and the first winding groove and the second winding groove are arranged vertically.

[0008] Furthermore, the air collecting shroud has two channel walls, which are arranged at intervals to form a flow guiding space. The two channel walls are respectively adjacent to the first magnetic core so that the first winding groove is located in the flow guiding space.

[0009] Furthermore, the expansion section has an air inlet and is connected to one end of the airflow guiding space, and the expansion section is composed of two outwardly expanding plates respectively connected to one end of the two channel walls.

[0010] Furthermore, the air collecting hood has another expansion section, which also has an air collecting port and connects to the other end of the air guiding space. The other expansion section is composed of two outwardly expanding plates, which are respectively connected to the other end of the two channel walls.

[0011] Furthermore, both channel walls are provided with two blocking edges extending toward the flow guide space and are combined on the winding frame.

[0012] Furthermore, the two channel walls are provided with at least a connecting portion between the opposing barrier edges.

[0013] Furthermore, a partition plate is provided on the winding section and is located between the first winding groove and the second winding groove.

[0014] Furthermore, the winding section is also provided with a top plate and the first winding groove is located between the top plate and the partition plate. The partition plate and the top plate are respectively provided with sliding groove edges, and the sliding groove edges form sliding grooves with the partition plate and the top plate respectively. The blocking edge slides into the sliding groove.

[0015] Furthermore, the air collection shroud is made of insulating material.

[0016] The beneficial effects of this utility model are: the addition of the air collector shroud allows external airflow or airflow to more easily enter the coil or winding, providing heat dissipation and cooling effects. Simultaneously, the air collector shroud 4 can further provide insulation and meet safety distance requirements, while also reducing material costs. Attached Figure Description

Detailed Implementation

[0018] Please see Figure 1 , Figure 2 and Figure 3 A slotted transformer structure with air collection includes a winding frame 1, a first magnetic core 2, a second magnetic core 3, and an air collection cover 4; wherein: the winding frame 1 has a foot 10 and a winding part 11 disposed on the foot 10. The winding part 11 can be vertically disposed on the foot 10 and is provided with a first winding groove 110 and a second winding groove 111, that is, the first winding groove 110 and the second winding groove 111 are arranged vertically on the foot 10, and a partition plate 112 can be provided on the winding part 11 between the first winding groove 110 and the second winding groove 111 for separation; Furthermore, a top plate 113 may be provided on the winding portion 11, and the first winding groove 110 may be located between the top plate 113 and the partition plate 112. Additionally, coils or windings (not shown) are wound on the first winding groove 110 and the second winding groove 111, respectively. The coil or winding wound on the first winding groove 110 may be a primary-side coil or winding, while the coil or winding wound on the second winding groove 111 may be a secondary-side coil or winding. In this embodiment, the first winding groove 110 is located above the second winding groove 111. Furthermore, the base 10 is provided with a plurality of downwardly extending pins 100, which are electrically connected to the aforementioned coils and allow the winding frame 1 to be soldered onto a circuit board (not shown).

[0019] The first magnetic core 2 is a magnetic element and is positioned opposite to the coil or winding wound on the first winding slot 110. Specifically, the first magnetic core 2 may be U-shaped and positioned across the winding frame 1 from above to correspond to the outside of the first winding slot 110, or it may be hollow within the winding portion 11 (e.g., Figure 2 As shown), the first magnetic core 2 has a columnar portion that extends into the winding portion 11 to correspond to the first winding groove 110; since this part is not within the scope of this invention and can be designed and modified by existing technology, it will not be described in detail.

[0020] The second magnetic core 3 is a magnetic element and is positioned opposite to the coil or winding wound on the second winding slot 111. Specifically, the second magnetic core 3 may be in the shape of an inverted "U" and may be placed across the winding frame 1 from below to correspond to the outside of the second winding slot 111. It may also be hollow inside the winding portion 11 (e.g., Figure 3 As shown), the second magnetic core 3 has a columnar portion that extends into the winding portion 11 to correspond to the second winding groove 111; since this part is not within the scope of this invention and can be designed and modified through existing technology, it will not be described in detail.

[0021] like Figures 1 to 4 As shown, the air collecting shroud 4 has two channel walls 40, a first expansion portion 41, and a second expansion portion 42. The two channel walls 40 are spaced apart and opposite to each other to form a flow guiding space 400. The two channel walls 40 are respectively located on both sides of the first magnetic core 2, so that the first winding groove 110 is located within the flow guiding space 400. The two channel walls 40 and the first winding groove 110 are spaced apart and opposite to each other, so that the two ends of the first winding groove 110 are interconnected or connected within the flow guiding space 400. The first expansion portion 41 has a first air collecting port 410 (i.e., as shown in the image). Figure 2 (As shown) and connected to one end of the flow guiding space 400, and the first expansion portion 41 can be composed of two outwardly expanding plates respectively connected to one end of the two channel walls 40 and protruding from the first magnetic core 2, the second expansion portion 42 has a second air inlet 420 (i.e., as ... Figure 3 As shown, the first expansion portion 41 and the second expansion portion 42 are two outwardly expanding plates connected to the other ends of the two channel walls 40 and protruding from the first magnetic core 2. Thus, the first expansion portion 41 and the second expansion portion 42 serve to concentrate and guide external airflow, allowing external airflow to be more easily concentrated or introduced into the first winding groove 110, or to be ventilated from both ends of the first winding groove 110, thereby providing heat dissipation and cooling for the coil or winding wound on the first winding groove 110. Specifically, the air collecting shroud 4, at least with the aforementioned first expansion portion 41, allows external airflow to more easily enter the first winding groove 110, thereby achieving the purpose of assisting the coil or winding in heat dissipation and cooling.

[0022] Furthermore, such as Figure 1 and Figure 5As shown, the air collecting hood 4 can be further made of insulating material, serving as insulation for the coil or winding wound within the first winding groove 110. Both channel walls 40 are provided with two blocking edges 43 extending towards the flow guiding space 400 or the first winding groove 110, facilitating their combination with the first winding groove 110 while also meeting safety distance requirements. Furthermore, the partition plate 112 and the top plate 113 each have a sliding groove edge 114 at their respective locations, forming a groove d1 between the partition plate 112 and the top plate 113. These two grooves d1 allow the two blocking edges 43 of the air collecting hood 4 to slide into and combine, thus providing insulation, meeting safety distance requirements, and reducing material costs.

[0023] To facilitate the integration of the air collecting hood 4 into a single unit, at least a connecting portion 430 can be integrally formed between the two opposing barrier edges 43 of the two channel walls 40. The connecting portion 430 can be located between the two plates of the first expansion portion 41 or the second expansion portion 42 (the figure in this embodiment takes the first expansion portion 41 as an example). This makes the air collecting hood 4 a single component, which is more convenient to assemble and also has greater strength in the overall structure.

[0024] The above-described structure results in a slotted transformer structure with air collection in this embodiment.

[0025] Therefore, the embodiment features a slotted transformer structure with air collection, which, by adding the air collection cover 4, allows external airflow or airflow to more easily enter the coils or windings, providing heat dissipation and cooling effects. Simultaneously, the air collection cover 4 can further provide insulation and meet safety regulations, while also reducing material costs.
