Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and specifically relates to a heat-dissipating transformer. Background Technique

[0002] A transformer is an electromagnetic component that uses the principle of electromagnetic induction to change the AC voltage. It mainly has functions such as voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. It is mainly composed of coils, magnetic cores, skeletons, insulating materials, etc. Among them, the winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils. The working principle of the transformer is that when an alternating current passes through the primary coil, an alternating magnetic flux is generated in the iron core (or magnetic core), causing a current (or voltage) to be induced in the secondary coil.

[0003] When the existing high-frequency transformers are in use, the magnetic material loss of the magnetic core and the copper resistance loss of the winding coil will cause the transformer to generate heat and have a relatively high temperature rise. The relatively high temperature will affect the service life of the magnetic core and insulating materials, and may also damage the surrounding electronic components.

[0004] Therefore, we propose a heat-dissipating transformer. Content of the Utility Model

[0005] The purpose of the utility model is to provide a heat-dissipating transformer to solve the problem of poor heat dissipation of the transformer proposed in the above background technique.

An arc surface is provided in the middle of the aluminum plate base, limiting convex platforms are provided on both sides of the aluminum plate base, and the two sides of the aluminum plate base at the arc surface are set as platforms.

[0007] Preferably, the platform is located between the arc surface and the limiting convex platform.

[0010] Preferably, the threaded holes are provided on the platform.

[0011] Preferably, the radian of the arc surface is the same as that of the wire package arc.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the transformer is working, the heat generated by the magnetic core and the wire coil is transferred to the heat dissipation teeth of the machine shell through the aluminum plate base.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: A heat dissipation type transformer includes a magnetic core 1, a wire coil 2 and an aluminum plate base 3. The wire coil 2 is installed inside the magnetic core 1, the aluminum plate base 3 is installed on the top of the magnetic core 1. An arc surface 5 is provided in the middle of the aluminum plate base 3, limiting bosses 4 are provided on both sides of the aluminum plate base 3. The parts of the aluminum plate base 3 on both sides of the arc surface 5 are platforms 6. The arc surface 5 of the aluminum plate base 3 is attached to the circular wire coil 2 of the transformer, and the two end planes are attached to the magnetic core 1 of the transformer. The limiting bosses 4 at the two side edges of the aluminum plate base are stuck on both sides of the magnetic core 1 to play a limiting role. A layer of thermal conductive adhesive is applied between the aluminum plate base 3 and the transformer, which can effectively transfer the heat of the transformer wire coil 2 and magnetic core 1 through the aluminum plate base 3. The other plane of the aluminum plate base 3 touches the machine shell and is locked with screws. Through the way of heat conduction, the heat of the transformer is quickly transferred from the aluminum plate base 3 to the heat dissipation teeth of the machine shell, achieving the effect of heat dissipation.

[0020] Among them, the platform 6 is located between the arc surface 5 and the limiting boss 4, and the limiting boss 4 is arranged at the two side edges of the aluminum plate base 3;

[0021] Threaded holes 7 are provided on the aluminum plate base 3, and the threaded holes 7 are arranged on the platform 6. The other plane of the aluminum plate base 3 touches the machine shell, and screws are used to pass through the threaded holes 7 for locking;

[0022] The radian of the arc surface 5 is the same as the arc of the wire coil 2, enabling the aluminum plate base 3 to better contact the wire coil 2 and quickly transfer the heat of the wire coil 2 to achieve a fast heat dissipation effect.

[0023] Working principle: Attach the arc surface 5 of the aluminum material base plate 3 to the circular wire coil 2 of the transformer, and attach the two end planes to the transformer core 1. The limiting bosses 4 at the two side edges of the aluminum plate base are stuck on both sides of the core 1 to play a limiting role. A layer of thermal conductive adhesive is applied between the aluminum plate base 3 and the transformer, which can effectively transfer the heat of the transformer wire coil 2 and the core 1 through the aluminum plate base 3. The other plane of the aluminum plate base 3 touches the machine shell, and screws are used for locking. Through the way of heat conduction, the heat of the transformer is quickly transferred from the aluminum plate base 3 to the heat sink teeth of the machine shell to achieve the heat dissipation effect. When the transformer is working, the heat generated by the core 1 and the wire coil 2 is transferred to the heat sink teeth of the machine shell through the aluminum plate base 3. The heat of the aluminum plate base 3 and the machine shell is transferred to the outside through the ways of heat conduction and heat convection to achieve the purpose of heat dissipation and temperature reduction, thereby solving the problem of high working temperature of the transformer and avoiding phenomena such as the failure of insulating materials and burning of the machine caused by high temperature of the transformer.
