Abstract

The invention is a power supply adapter, comprising: a transformer composed of iron core, primary winding and secondary winding; a small case, closely packaging the transformer and comprising uniformly distributed nano carbon ball material. The invention also provides a method for manufacturing the power supply adapter, comprising the following steps of: assembling the iron core, primary winding and secondary winding into a transformer; placing the transformer into a mould; closely enveloping the case of the molded transformer adapter with the nano carbon ball- added material by a molding device.

Description

【Technical field】 [0001] The invention relates to a power adapter and a manufacturing method thereof, in particular to a power adapter using nanometer materials for heat dissipation and a manufacturing method thereof. 【Background technique】 [0002] A power adapter is used to step down a power supply voltage so that electrical equipment such as a charger that requires a low voltage can operate. [0003] With the development of technology, when the power adapter needs to provide higher power, the heat generated inside it will also increase relatively. In order to avoid overheating and affect its performance, heat dissipation has gradually become the primary problem to be solved in the development of power adapters. Since the current power adapter is generally a closed design, it cannot dissipate heat through forced convection through an external fan like a power supply or a computer, but must dissipate heat through heat conduction and natural convection. However, the thermal...
