Description

A kind of fast charger of rapid cooling
Technical field
The utility model is related to the technical field of charger, the fast charger of more particularly to a kind of rapid cooling.
Background technology
With popularizing for smart mobile phone, frequent use of mobile phone causes the depletion rate of its electricity to be also getting faster, this is just So that requirement of the people for charging rate is higher and higher, the Charging Specification of the 5V/1A of script cannot increasingly meet people couple In the demand of charging rate, therefore, more and more mobile phones are initially configured quick charger and charge at present.
The electric current of existing fast charger can generally reach more than 1.5A, this just increases the thermal diffusivity to charger The requirement of energy and internal electronic element.By taking capacitance as an example, for high-voltage capacitance in the case where keeping capacity constant, volume is also more next Smaller and also more preferable in terms of pressure resistance and temperature, pressure resistance can not enough puncture capacitance, and heatproof can not enough pop capacitance.In order to Heat dissipation effect is improved, the volume of existing fast charger is also compared also increases many with the volume of common charger.
However, due to the increase of charging current, the fever of the component of fast charger has also become larger very much, although increase The volume of charger increases heat-dissipating space, since the charging circuit of existing quick charger is to be enclosed in charger case Inside, the heat of the generation of component is difficult to exhale, and causes existing fast charger that can be generated in charging process The problem of shell fever is serious.And the problem of charger internal excessively high not only easy aging speed for accelerating component, meanwhile, when If cannot be exhaled in time in charger case, it is easy to cause and burns circuit and even result in the hidden danger that charger burns explosion.
Invention content
In view of the problems of the existing technology, the main purpose of the utility model is to provide a kind of fast charge of rapid cooling and fills Electric appliance all in the radiating efficiency for improving fast charger, reduces the phenomenon that it generates heat, is hot in use, reduces charging Hidden danger.
To achieve the above object, the utility model proposes rapid cooling fast charger, including shell and button The bottom cover of shell one end is connected on, the other end is equipped with plug;Bottom cover is equipped with USB charging interfaces, and enclosure is equipped with charging electricity Road plate, the plug are electrically connected with the USB charging interfaces with the charging circuit board.The both sides of the shell are equipped with heat dissipation Hole, the component outside embedding side heat-conducting glue of the charging circuit board, and the outside of the heat-conducting glue is equipped with metal heat-conducting cover, The metal heat-conducting cover position opposite with the heat emission hole is equipped with thermally conductive sheet.
Further, the heat-conducting glue is silica gel.
Further, the heat emission hole is equipped with anti-dust filter mesh towards the side in the shell.
Further, the filter screen is metal filter screen, is in contact with the thermally conductive sheet.
The utility model is led by one layer of heat-conducting glue of embedding on charging circuit board, then in the outside of heat-conducting glue setting metal Heat cover so as to quickly absorb the heat that the component on charging circuit board generates in charging process, is passed through by metal heat-conducting cover The thermally conductive sheet for being arranged on heat dissipation hole site is in contact with cool ambient air, heat is quickly taken away, so as to reduce fast charger The phenomenon that generating heat in use, is hot reduces charging hidden danger.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, other attached drawings can also be obtained according to the structure shown in these attached drawings.
Fig. 1 is the stereogram of one embodiment of fast charger of the utility model rapid cooling;
Fig. 2 is the transverse sectional view of the fast charger of the utility model rapid cooling;
The utility model aim is realized, the embodiments will be further described with reference to the accompanying drawings for functional characteristics and advantage.
Specific embodiment
The utility model proposes a kind of fast chargers of rapid cooling.
With reference to Fig. 1-2, Fig. 1 is the stereogram of one embodiment of fast charger of the utility model rapid cooling, and Fig. 2 is this The transverse sectional view of the fast charger of utility model rapid cooling.
As shown in Figs. 1-2, in the utility model embodiment, the fast charger of the rapid cooling includes:Shell 100, And the bottom cover 110 of 100 one end of shell is snapped onto, the other end is equipped with plug 120;Bottom cover 110 is equipped with USB charging interfaces 111, shell 100 is internally provided with charging circuit board 200 (not shown), the plug 120 and the USB charging interfaces 111 with The charging circuit board 200 is electrically connected.The both sides of the shell 100 are equipped with heat emission hole 130, the member of the charging circuit board 200 Device exterior embedding side heat-conducting glue, and the outside of the heat-conducting glue is equipped with metal heat-conducting cover 300, the metal heat-conducting cover 300 The position opposite with the heat emission hole 130 is equipped with thermally conductive sheet 310.
Specifically, in the present embodiment, the silica gel with thermal conductive resin that the heat-conducting glue uses, quickly to absorb And the heat of the component on charging circuit board 200, and transfer heat to metal heat-conducting cover 300.
