Description
Technical Field
The invention relates to a mobile phone accessory, in particular to a mobile phone shell.
Background
Nowadays, a mobile phone becomes one of indispensable communication tools in life of people, and along with the increase of functions of the mobile phone, the heat productivity of the mobile phone is higher and higher when the mobile phone is used; when the mobile phone is overheated, the power consumption of the mobile phone is correspondingly increased, so that the standby time of the mobile phone is shortened; when the temperature of the mobile phone is too high, the mobile phone may even be halted and the like, and potential safety hazards such as explosion and the like are easy to occur at the same time; particularly, in summer, the mobile phone can be scalded by using the mobile phone for a short time, which seriously shortens the service life of the mobile phone; in addition, people like to use the protective shell for the mobile phone, the mobile phone shell can prevent the mobile phone from being worn when the mobile phone is dropped by mistake, but the heat dissipation of the mobile phone is seriously influenced, and the mobile phone shell made of poor materials can deform under the high-temperature baking of the mobile phone, so that the protective shell cannot protect the mobile phone, the mobile phone can be overheated, and the service life of the mobile phone can be shortened; some cell-phone shell manufacturers choose metal material for use in order to guarantee the radiating effect, and this kind of cell-phone shell is firm and can high-efficient heat conduction, but serious separation cell-phone signal influences normal communication, and this kind of way has got unreliated.

After the heat on the back of the mobile phone is absorbed by the traditional mobile phone shell, the heat can be dissipated only through the heat conduction of the material of the traditional mobile phone shell, so that the heat dissipation efficiency is low; the invention uses the heat of the mobile phone to do work on the driving section, converts part of the heat energy into kinetic energy and carries out primary heat dissipation; meanwhile, the high-temperature surface is directly rotated and exposed in the air through the rotation of the heat dissipation cylinder, so that rapid heat conduction is carried out, and secondary heat dissipation is carried out; the heat dissipation efficiency of the mobile phone shell is effectively improved; the invention has exquisite structure, can realize the autonomous rotation and the rapid heat dissipation of the shell without external power supply, and simultaneously does not interfere the signal of the mobile phone.
Preferably, the number of the partition plates in each heat dissipation cylinder is 6-8; the structure can ensure normal heat dissipation of the mobile phone cover, and meanwhile, the production cost cannot be excessively increased.
Preferably, stripes with different colors are coated on the heat dissipation cylinders; so as to increase the ornamental of cell-phone shell, can know which position calorific capacity of cell-phone is great through the slew velocity of observing each stripe simultaneously to whether the side is observed the cell-phone and is generated heat normally.
Preferably, 2-3 different background pictures are divided into picture strips with equal width, the picture strips of each picture are attached to the cylinder wall of the heat dissipation cylinder correspondingly, namely the picture strips belonging to different background pictures are attached to the cylinder wall of each heat dissipation cylinder in an equal arc surface manner; with the rotation of the heat dissipation cylinder, the mobile phone shell can alternately display a plurality of background pictures, so that the ornamental value and the style of the mobile phone shell are effectively improved.
