Description

Technical Field

[0001] The utility model relates to the technical field of flat-plate transformers, in particular to a flat-plate transformer with auxiliary heat dissipation. Background Art

[0002] The flat transformer, also known as the planar transformer, is a new type of transformer. Compared with the traditional transformer, the biggest difference is the iron core and coil winding. The flat transformer uses a small-sized E-type, RM-type or toroidal ferrite transformer housing, which is usually made of high-frequency power ferrite material and has a lower leakage inductance at high frequencies. The flat transformer is widely used in power supply equipment and devices. For example, it can be used as an AC / DC and DC / DC converter in single-ended forward, flyback, half-bridge, full-bridge and push-pull converters. It is particularly suitable for low-voltage, high-current converters. Therefore, it is particularly suitable for contemporary computer power supplies.

[0003] The working principle of the transformer is to transfer electrical energy from one circuit to another through electromagnetic induction. In this process, a large amount of heat will be generated. If the heat is not dissipated in time, it will greatly affect the performance and life of the transformer. At the least, it will affect the output power of the device, and at the worst, it may damage the device. In order to solve the heat dissipation problem, flat transformers usually adopt some heat dissipation structures, such as heat sinks, heat pipes, etc. These heat dissipation structures can help the heat sink to quickly conduct heat away, thereby improving the heat dissipation effect. At the same time, a fan can also be used for cooling to further improve the heat dissipation effect. In general, the flat transformer needs to dissipate heat because its internal parts will generate a lot of heat during operation. If it cannot be dissipated in time, it will have a serious impact on the performance and life of the transformer. Therefore, a flat transformer with auxiliary heat dissipation will be needed.

[0004] After searching, a flat transformer with a heat dissipation structure is disclosed in the announcement number: CN218159882U. A flat transformer with a heat dissipation structure is provided, including a transformer body, a first fixed shell and a second fixed shell. The first fixed shell is arranged on one side of the transformer body, and the second fixed shell is arranged on the other side of the transformer body. An auxiliary structure is arranged at the connection between the transformer body and the second fixed shell. A pin is arranged at the bottom end of the transformer body, and a rust-proof structure is arranged on the surface of the pin. The heat dissipation structure is arranged on one side of the first fixed shell and the second fixed shell. The utility model is provided with a heat dissipation structure. During the use of the transformer body, it is easy to generate heat due to the work of its internal parts. If it only relies on its own heat dissipation, the heat dissipation effect will be poor. Therefore, the use of a heat conductive sheet, a heat sink and a fan can accelerate the heat dissipation effect of the transformer body, so that the transformer body is more efficient in heat dissipation, thereby improving the heat dissipation effect.

[0005] However, there are still some deficiencies in the above-mentioned application and the above-mentioned patent, such as the inability to adjust the distance between the heat sink and the heating element according to the specific hardware configuration and working status. The above-mentioned technology can only accelerate the heat dissipation effect of the transformer body by using thermal conductive sheets, heat sinks and fans, so that the transformer body is more efficient in heat dissipation, thereby improving the heat dissipation effect, but it cannot adjust the distance between the heat sink and the heating element according to the specific hardware configuration and working status, so as to optimize the heat dissipation effect of the equipment.
