Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, in particular to a novel high-power transformer. Background Art

[0002] Transformers, as core components in power systems and various electrical equipment, are mainly used to achieve voltage level conversion, impedance matching, and electrical isolation. The main structure of the transformer includes coils and iron cores. These structures generate heat during operation. In order to ensure that the device can work stably, its heat dissipation needs to be improved.

[0003] Although the existing device improves the speed of heat dissipation through relevant structures, the structural area used for heat dissipation is small and thus the heat dissipation efficiency is still not high enough.

[0004] For example, a new type of high-power transformer with Chinese utility model application number CN202223242001.6 includes two fixed plates and a coil. Trapezoidal blocks are fixedly mounted on the adjacent sides of the two fixed plates. Arc-shaped slots are defined on the upper sides of the two trapezoidal blocks, and the coil is wound around the two arc-shaped slots. The two fixed plates are also provided with arc slots on the adjacent sides. A base is bonded to the front of the two fixed plates. Heat dissipation slots are defined on the two trapezoidal blocks, and the adjacent sides of the two trapezoidal blocks are bonded to each other. This device has a small structural area for heat dissipation, resulting in insufficient heat dissipation efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a new type of high-power transformer to solve the problems raised in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a new type of high-power transformer, comprising:

[0007] A support frame and a slot constructed at the center of the bottom of the support frame, wherein an iron core is inserted into the inner side of the slot;

[0008] The side wall of the iron core is wound with a coil, and two heat-conducting plates are symmetrically nested and installed on the inner side of the support frame, and the heat-conducting plates are attached to the corresponding sides of the coil. A plurality of heat-conducting rods are uniformly integrally formed on the side of the heat-conducting plate away from the coil, and the heat-conducting rods pass through the support frame and are flush with the corresponding side outer wall of the support frame. The outer walls on both sides of the support frame are symmetrically provided with a plurality of air holes corresponding to the iron core, and the air holes are connected to the corresponding sides of the slot.

[0009] In a further embodiment, fixing plates are integrally formed on the bottoms of the symmetrical outer walls of the support frame, and a plurality of fixing holes are arranged side by side on the tops of the fixing plates.

[0010] In a further embodiment, the bottom of the fixing plate is flush with the bottom of the support frame.

[0011] In a further embodiment, four connecting holes are distributed in a rectangular shape on one side of the support frame, and the connecting holes pass through the other side of the support frame.

[0012] In a further embodiment, the heat conducting plate is flush with the top of the support frame, and a heat-resistant adhesive layer is bonded between the heat conducting plate and the support frame.

[0013] In a further embodiment, a shock-absorbing pad is supported between the heat-conducting plate and the bottom of the coil, and the shock-absorbing pad is nested in a corresponding side of the support frame.

[0014] In a further embodiment, the heat conducting plate and the heat conducting rod, and the support frame and the fixing plate are all cast into an integrally formed structure.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are:

[0016] In this new type of high-power transformer, although the existing solution increases the heat dissipation rate by designing heat dissipation grooves on the iron core, the area of ​​the related structure is not large enough, so the heat dissipation is not efficient. This solution uses heat conduction plates on both sides to conduct heat from the coil, and then the heat is dissipated through multiple heat conduction rods. At the same time, multiple air holes are used to dissipate heat from the surface of the iron core. These structures can increase the contact area and make the heat dissipation more efficient.

[0017] This new high-power transformer adopts multiple structures to achieve higher heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to adopt multiple structures to make the heat dissipation more efficient, such as Figures 1 to 4 As shown, it includes: a support frame 1 and a slot constructed in the center of the bottom of the support frame 1, and an iron core 2 is inserted into the inner side of the slot, and the side wall of the iron core 2 is wound with a coil 3. The iron core 2 and the coil 3 can constitute the main body of the transformer, and can work using the existing principle (it is not an improvement direction, so it will not be described in detail). The inner side of the support frame 1 has two symmetrical mounting slots, and a heat conducting plate 4 is nested and installed in the mounting slot, and the heat conducting plate 4 is attached to the corresponding side of the coil 3, which can quickly conduct the heat from the surface of the coil 3. The heat conducting plate 4 is flush with the top of the support frame 1, and a heat-resistant adhesive layer is bonded between the heat conducting plate 4 and the support frame 1 to ensure that the heat conducting plate 4 is firmly connected.

[0029] A plurality of heat-conducting rods 5 are uniformly cast and integrally formed on the side of the heat-conducting plate 4 away from the coil 3. The integrally cast structure has high strength and durability. The heat-conducting rods 5 pass through the support frame 1 and are flush with the corresponding side outer wall of the support frame 1. Heat can be dissipated through the plurality of heat-conducting rods 5. The outer walls on both sides of the support frame 1 are symmetrically provided with a plurality of air holes 6 corresponding to the iron core 2, and the air holes 6 are connected to the corresponding sides of the slots. The heat on the surface of the iron core 2 can be conducted out from the air holes 6 through the air.

[0030] One side of the support frame 1 is provided with four connecting holes 10 in a rectangular shape, and the connecting holes 10 pass through the other side of the support frame 1. Multiple support frames 1 can be installed side by side. At this time, external screws and nuts can be connected through the corresponding connecting holes 10 to fix adjacent support frames 1.

By screwing bolts into the fixing holes 9, the device can be stably fixed to the corresponding side of the external structure.

[0031] How it works

[0032] This new type of high-power transformer generates a certain amount of heat when the device is working. The heat on the surface of the coil 3 is transferred to the surface of the heat-conducting plates 4 on both sides, and then dissipated through multiple heat-conducting rods 5. At the same time, the heat on the surface of the iron core 2 can be transferred out from the air holes 6 through the air. The above-mentioned structural combination can make the heat dissipation efficiency higher.
