Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer technology, specifically a dry-type transformer with full-area heat dissipation. Background Technology

[0002] A transformer consists of an iron core (or magnetic core) and coils. The coils have two or more windings; the winding connected to the power source is called the primary coil, and the others are called secondary coils. It can transform AC voltage, current, and impedance. A simple iron-core transformer consists of an iron core made of a soft magnetic material and two coils with unequal numbers of turns wound around the core. The function of the iron core is to strengthen the magnetic coupling between the two coils. To reduce eddy current and hysteresis losses within the iron core, it is made of laminated, varnished silicon steel sheets. There is no electrical connection between the two coils, which are wound with insulated copper (or aluminum) wire.

[0003] Application number CN202222113323.4 discloses a dry-type transformer, including a housing and other structures. This invention uses a temperature control component to detect when the internal temperature of the housing exceeds a threshold, controlling the operation of cooling fans. The cooling fans expel hot air from inside the housing through heat dissipation channels, achieving external air circulation and rapid heat dissipation, effectively protecting the transformer components. However, in practical use, while this application can cool the entire transformer component, the simultaneous operation of multiple cooling fans undoubtedly increases energy consumption. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A dry-type transformer with full-area heat dissipation includes a power generation mechanism, an internal heat dissipation mechanism, and an external heat dissipation mechanism. The power generation mechanism includes a transformer body and multiple outer shells fitted onto the outside of the transformer body. The internal heat dissipation mechanism includes an internal heat dissipation pipe connected between the multiple outer shells, multiple middle pipes connected and communicating with the internal heat dissipation pipes, an arc-shaped plate installed inside the outer shells and fitted onto the front end of the middle pipes, multiple side pipes connected and communicating with the internal heat dissipation pipes, and a hot air pipe connected to the front side of the outer shells. The external heat dissipation mechanism includes two external heat dissipation pipes installed at the top and bottom of the internal heat dissipation pipes and an air guide shroud located outside the air outlet of the external heat dissipation pipes.

[0007] By adopting the above technical solution, an external air source (cold air) is injected into the internal and external heat dissipation pipes. Then, the cool air in the internal heat dissipation pipes flows out through the central and side pipes. The cool air flowing out of the central pipe directly acts on the transformer body, while the cool air flowing out of the side pipes evenly fills the interior of the outer shell along the outer wall of the arc plate. Then, the hot air is discharged from the hot air pipe. At the same time, the cool air flowing out of the external heat dissipation pipes, after being guided by the air guide shroud, cools the surrounding area of ​​the outer shell. This achieves full-area heat dissipation of the internal and external environments. The heat dissipation operation relies on only one air source, effectively reducing heat dissipation energy consumption.

[0008] In a preferred embodiment, the present invention can be further configured such that: the arc-shaped plate is disposed on the rear side of the transformer body and a gap is formed between it and the transformer body, and the interior of the central tube is connected to the interior of the gap.

[0009] In a preferred embodiment, the present invention can be further configured as follows: multiple side tubes are arranged in pairs, and multiple groups of side tubes are located inside multiple outer shells respectively. Two side tubes in each group are located on both sides of the central tube, and the side tubes are located on the rear side of the arc plate.

[0010] In a preferred embodiment, the present invention can be further configured such that: two clamping plates are installed at the top and bottom of the transformer body, and the outer surface of the clamping plates is coated with insulating paint.

[0011] In a preferred embodiment, the present invention can be further configured such that: two support plates are connected between the clamping plate and the air guide shroud, and the two support plates are respectively close to both sides of the air guide shroud.

[0012] In a preferred embodiment, the present invention can be further configured such that: the length of the air guide shroud is greater than the sum of the diameters of the plurality of outer shells, the width of the air guide shroud is greater than the diameter of the outer shells, and the interior of the air guide shroud is provided with an arc surface.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] In this invention, an external air source (cold air) is injected into the inner and outer heat dissipation pipes. The cool air in the inner heat dissipation pipe flows out through the middle and side pipes. The cool air flowing out of the middle pipe directly acts on the transformer body, while the cool air flowing out of the side pipe evenly fills the interior of the outer shell along the outer wall of the arc plate. Then, the hot air is discharged from the hot air pipe. At the same time, the cool air flowing out of the outer heat dissipation pipe is guided by the air guide shroud to cool the surrounding area of ​​the outer shell. This achieves full-area heat dissipation of the internal and external environments. The heat dissipation operation relies on only one air source, effectively reducing heat dissipation energy consumption. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a dry-type transformer with full-area heat dissipation.

[0029] Example 1:

[0030] Combination Figure 1-5 As shown, the present invention provides a dry-type transformer with full-area heat dissipation, including a power generation mechanism 100, an internal heat dissipation mechanism 200 and an external heat dissipation mechanism 300. The power generation mechanism 100 includes a transformer body 110 and a plurality of outer shells 120 sleeved on the outside of the transformer body 110.

[0031] An internal heat dissipation mechanism 200 includes an internal heat dissipation pipe 210 connected between multiple outer shells 120, multiple central pipes 220 connected and communicating with the internal heat dissipation pipes 210, an arc-shaped plate 230 installed inside the outer shell 120 and sleeved on the front end of the central pipes 220, multiple side pipes 240 connected and communicating with the internal heat dissipation pipes 210, and a hot air pipe connected to the front side of the outer shell 120.

[0032] The external heat dissipation mechanism 300 includes two external heat dissipation pipes 310 installed at the top and bottom of the internal heat dissipation pipe 210, and an air guide shroud 320 located outside the air outlet of the external heat dissipation pipes 310.

[0033] Furthermore, the arc-shaped plate 230 is located on the rear side of the transformer body 110 and forms a gap between it and the transformer body 110. The interior of the central tube 220 is connected to the interior of the gap. The layout design of the arc-shaped plate 230 provides conditions for cool air to directly act on the transformer body 110.

[0034] Furthermore, multiple side pipes 240 are arranged in pairs, forming multiple groups. The multiple groups of side pipes 240 are located inside multiple outer shells 120. The two side pipes 240 in each group are located on both sides of the central pipe 220. The side pipes 240 are located behind the arc plate 230. The layout design of the side pipes 240 can guide the direction of cool air, so that the hot air inside the outer shell 120 can be completely discharged from the hot air pipe.

[0035] Furthermore, the length of the air guide shroud 320 is greater than the sum of the diameters of the multiple outer shells 120, the width of the air guide shroud 320 is greater than the diameter of the outer shells 120, and the interior of the air guide shroud 320 is curved. The size design of the air guide shroud 320 can completely dissipate heat around the multiple outer shells 120, ensuring the heat dissipation effect.

[0036] Example 2:

[0037] Combination Figure 1 As shown, based on Embodiment 1, two clamping plates 400 are installed at the top and bottom of the transformer body 110. The outer surface of the clamping plates 400 is coated with insulating paint. The clamping plates 400 can improve the stability of the transformer body 110 structure.

[0038] Example 3:

[0039] Combination Figure 1 and Figure 5 As shown in the above embodiment, two support plates 500 are connected between the clamping plate 400 and the air guide cover 320. The two support plates 500 are respectively close to both sides of the air guide cover 320. The support plates 500 can fix the air guide cover 320 and improve the installation firmness of the air guide cover 320.

[0040] The working principle and usage process of this utility model are as follows: When this device is put into actual use, an external air source (cold air) is injected into the inner heat dissipation pipe 210 and the outer heat dissipation pipe 310. Then, the cool air in the inner heat dissipation pipe 210 flows out through the middle pipe 220 and the side pipe 240. The cool air flowing out from the middle pipe 220 directly acts on the transformer body 110. Then, the cool air flowing out from the side pipe 240 evenly fills the interior of the outer shell 120 along the outer wall of the arc plate 230. Then, the hot air is discharged from the hot air pipe. At the same time, the cool air flowing out from the outer heat dissipation pipe 310, after being guided by the air guide shroud 320, cools down the area around the outer shell 120. This achieves comprehensive heat dissipation of the internal and external environments. The heat dissipation operation relies on only one air source, which effectively reduces the heat dissipation energy consumption.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
