Preparation method for cellphone charger capable of automatically dissipating heat

Abstract

The invention provides a preparation method for a cellphone charger capable of automatically dissipating heat, and the cellphone charger comprises a housing and charging inner cores. The housing comprises an upper housing and a lower housing, and the interior of the upper housing is provided with one charging inner core, and a big rotating shaft is disposed above the charging inner core. The big rotating shaft is provided with a fan. The interior of the lower housing is provided with one charging inner core, and a cavity is disposed below the charging inner core. The interior of the cavity is provided with a plug. According to the invention, the housing comprises the upper housing and the lower housing, and the upper and lower housings are enabled to be separated under the mutual action of a telescoping inner rod and a telescoping outer rod. A sufficient opened pace is reserved. The interior of the upper housing is provided with the fan, and the inner surfaces of the upper and lower housings are provided with cooling fins. The interior of the charger is enabled to make contact with air as much as possible, thereby achieving a heat dissipation effect.

Description

technical field [0001] The invention relates to a preparation method of a mobile phone charger with automatic heat dissipation. Background technique [0002] The current smartphones generally suffer from excessive energy consumption and excessive heat generation, resulting in a sharp decline in user experience; thus, heat dissipation has become an important research direction. Most of the current heat sinks only use the natural heat conduction of metals, that is, metal materials are used on heat dissipation devices such as support frames of mobile phones, so that heat can be quickly taken away by metals. The advantage of doing this is that the cost is low and the reliability is high. The disadvantage is that the natural heat conduction of metal still cannot play a good role when the mobile phone heats up a lot. At present, there is no special heat dissipation device on the mobile phone chargers commonly used. When the mobile phone is charged for a long time or the mobile p...

Problems solved by technology

[0003] The problem to be solved by the present invention is that when the mobile phone is charged for a long time or the mobile phone is charged quickly, the charger is easy to generate heat, and at the same time, the temperature of the mobile phone battery is too high, thus affecting the service life of the mobile phone battery and increasing the risk of charging , so it is not safe to use
