Description

Technical Field

[0001] This utility model relates to the field of transformer technology for power supply of charging pile modules, specifically a charging pile transformer with easy heat dissipation. Background Technology

[0002] With the rapid expansion of the electric vehicle market, the performance and efficiency of charging piles, as key facilities for the energy supply of electric vehicles, are of paramount importance. In the composition of the power supply module of the charging pile, the transformer plays a crucial role, responsible for DC-DC conversion, which directly affects the overall efficiency of the power supply module of the charging pile.

[0003] Common charging pile transformers also have some problems. For example, the traditional transformer structure generates a lot of heat in the windings and core due to the large current during use. This results in the transformer core and winding temperatures being too high, and the heat cannot be dissipated, which can easily affect the use of the transformer.

[0004] Therefore, we propose a heat-dissipating charging pile transformer to improve upon the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a charging pile transformer that is easy to dissipate heat, so as to solve the problem mentioned in the background art that the transformer core and winding temperature is too high, the heat cannot be dissipated, and it is easy to affect the use of the transformer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-dissipating charging pile transformer, comprising an upper magnetic core, an opening at the bottom of the upper magnetic core, an opening at the top of the lower magnetic core, the two being connected to form an inner cavity, a protrusion being provided in the inner cavity, a racetrack-shaped winding being installed on the protrusion, first reserved slots being provided on the left and right sides of the upper magnetic core, second reserved slots being provided on the left and right sides of the lower magnetic core, a through hole being provided at the middle position of the upper and lower magnetic cores, and extension blocks being processed on the left and right sides of the upper and lower ends of the upper and lower magnetic cores respectively.

[0007] As a further technical solution of this utility model, the first reserved slot and the second reserved slot are the same size, and the first reserved slot and the second reserved slot are aligned.

[0008] As a further technical solution of this utility model, the extension blocks are provided in multiple sets, and the extension blocks are symmetrically distributed about the horizontal center line of the upper magnetic core.

[0009] As a further technical solution of this utility model, the bottom ends of the upper magnetic core and the lower magnetic core are provided with a base, and the left and right sides and the front and rear ends of the top of the base are respectively fixedly connected with connecting rods.

[0010] As a further technical solution of this utility model, the connecting rod is respectively provided on the left and right sides of the bottom end of the upper magnetic core and the lower magnetic core, and the base is provided at the bottom end of the winding.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the easily heat-dissipating charging pile transformer not only facilitates heat dissipation of the transformer, but also facilitates protection of the transformer;

[0012] (1) By setting a first reserved slot, a through hole, an extension block and a second reserved slot, the first reserved slot, the through hole and the second reserved slot are opened to form an air channel on the upper magnetic core and the lower magnetic core, so as to dissipate heat from the upper magnetic core, the lower magnetic core and the winding, effectively reducing the temperature of the upper magnetic core, the lower magnetic core and the winding, and preventing the transformer heat from being difficult to dissipate quickly, which leads to poor transformer performance. The upper magnetic core and the lower magnetic core are added without affecting the winding.

[0013] (2) By setting a base and connecting rod, the base can support the upper and lower magnetic cores, making the bottom of the upper and lower magnetic cores moisture-proof and corrosion-proof. The base can also protect the transformer from shock and noise, thereby further increasing the service life of the transformer. Attached Figure Description

[0025] Working principle: In use, this utility model forms air ducts on the upper magnetic core 1 and lower magnetic core 3 by opening the first reserved slot 2, through hole 4 and second reserved slot 9, which dissipates heat from the upper magnetic core 1, lower magnetic core 3 and winding 7, effectively reducing the temperature of the upper magnetic core 1, lower magnetic core 3 and winding 7, preventing the transformer from having difficulty in dissipating heat quickly, which would lead to poor transformer performance. The upper magnetic core 1 and lower magnetic core 3 are added with extension blocks 5 without affecting the winding 7. The base 6 can support the upper magnetic core 1 and lower magnetic core 3, making the bottom of the upper magnetic core 1 and lower magnetic core 3 moisture-proof and corrosion-proof.
