Abstract
This invention relates to a radiator for mobile communication equipment, which contains printed circuit board, shield frame and shield cover, wherein the printer circuit board having heating element, shield frame located around the radiation device, said shield frame and cover forming a shield space, shield cover and heating device conducting and radiating heat, the large area metal shield cover can quick radiates heat in heating device to raise equipment reliability.
Description
Technical field
The relevant a kind of heat abstractor of the present invention, the heat abstractor of especially relevant a kind of mobile communication equipment.
Background technology
Current rhythm of life is more and more faster, and for effective connection, various mobile communication equipments arise at the historic moment.People are also more and more frequent for the use of mobile communication equipment, and for the ease of carrying, mobile communication equipment also develops towards compact direction, and the continuous increase of its speed and function, make that the heating phenomenon of some devices of mobile phone is very serious.
In addition, in order to prevent the phase mutual interference of electric signal, need be to some radio-frequency power amplifier (RFPA in the mobile phone for example, Radio Frequency Power Amplifier) and the function element of main big current drain such as charging chip (CHARGEIC) shield, and these function elements are main heater members, so heater members is following centering on of metal shielding like this, and the radiating rate of heater members is slowed down.In compact mobile communication equipment, the speed of radiating rate can produce influence greatly to the task performance of device and life-span, is to need the problem that solves so how to effectively utilize that existing device dispels the heat.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of radiator for mobile communication device that can efficiently radiates heat is provided.
The object of the present invention is achieved like this: a kind radiator for mobile communication device, comprise printed circuit board (PCB), mask frame and screening cover, wherein printed circuit board (PCB) is provided with heater members, mask frame is arranged at the periphery of heater members, screening cover combines with mask frame and forms a shielding space, described screening cover comprises end face, and the corresponding heater members of described end face position forms a groove downwards; Have heat conduction cloth between described groove and the heater members and carry out heat loss through conduction.
Compared with prior art, the invention has the beneficial effects as follows: owing to have bigger area of dissipation at screening cover, and utilize existing device can not increase the volume and the weight of mobile communication equipment, and can dispel the heat effectively, guarantee the reliability of mobile communication equipment.
Description of drawings
Fig. 1 is the structure chart of first embodiment of radiator for mobile communication device of the present invention.
Wherein:
1 printed circuit board (PCB), 2 heater members
3 screening covers, 4 mask frame
5 heat conduction cloth, 6 grooves
7 buckling partss, 8 end faces
Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
See also shown in Figure 1ly, in the present embodiment, mobile communication equipment is a mobile phone, radiator for mobile communication device of the present invention comprises printed circuit board (PCB) 1, this printed circuit board (PCB) 1 is provided with heater members 2, is provided with mask frame 4 around heater members 2, and mask frame 4 is made by foreign blank.Above-mentioned mask frame 4 and printed circuit board (PCB) 1 vertical setting.Screening cover 3 comprises buckling parts 7 and end face 8, and both vertically are provided with, and buckling parts 7 can be interlocked with above-mentioned mask frame 4, thereby forms a shielding space, and heater members 2 is effectively shielded.The position of corresponding heater members 2 forms a groove 6 downwards on the above-mentioned end face 8.Between groove 6 and above-mentioned heater members 2, has heat conduction cloth 5, the heat that heater members 2 is sent can be conducted to screening cover 3, because screening cover 3 is to be made by foreign blank, so the speed of its heat loss through conduction is very fast, and screening cover 3 is interlocked with mask frame, so also can utilize mask frame 4 further to dispel the heat.
In sum, the present invention has finished inventor's purpose, owing to do not increase any device, so can not increase the weight and the volume of mobile communication equipment, satisfy the compact requirement of mobile communication equipment, and can dispel the heat effectively, in addition, the setting of heat conduction cloth also can avoid the metallic shield lid to damage heater members.
