With the high pass of the flagship processor chip Qualcomm Snapdron 855 mobile platform, the supply of the flagship system issued by Qualcomm last year is stable, in addition to the flagship models launched by major manufacturers, using the flagship configuration game mobile phone also begins to update. On March 18, the black shark officially released a new generation of mobile phone black shark game mobile phone 2, which not only used Qualcomm Flagship chip, the 855 mobile platform, but also specifically for signal, heat dissipation, etc. The decision of this issue brings everyone to the dismantling of the black shark game mobile phone 2.

Features: Screen compact L tower liquid cooling heat L screen down fingerprint
Preliminary dismantling:
The black shark game mobile phone 2 uses a front demultiplexing design, first put the heating platform on the side of the mobile phone screen, the heating temperature is approximately 80 ° C, and then slowly open the screen with the lens. After opening, you can see that the position of the heat sink is a large-scale hot copper plate, and the connection screen and the sub-board BTB soft plate are located under the lower part of the phone, and the BTB soft board interface on the heat dissipation plate is fixed to the heat dissipation plate.
After opening the heat dissipation plate, you can see the black shark game mobile phone 2 has a very similar "eight panfish" soft board that is very similar to the Sony mobile phone, and the Sony will design the soft board on the back cover, while the black shark game mobile phone 2 Designed to the battery.

Removing the snapshots can also remove the fingerprint identification module and the earpiece module. The USB interface soft board is fixed by a metal cover and a screw, and the heat dissipation plate corresponds to the position of the main board BTB interface with a user buffered foam.
Remove three connectors, sub-board FPC soft boards and a separate USB interface soft board to remove the motherboard and sub-plates. The black shark game mobile phone 2 uses four RF coaxial lines, two short coaxial lines for connecting to the LED softboard on both sides, and two long coaxial lines are connected to the panel. This design is the X-type antenna layout, which is the advantage of improving the stability of the signal.
The light sensor is made alone into a module, which is connected to the motherboard via the BTB interface, and the Silicone sleeve is also protected.
There is a metal cover on the BTB interface on the back of the motherboard as protection.
The battery of the black shark game phone 2 is fixed to the back cover by two easy-to-pull gums. It is more particular that the battery is not connected to the motherboard, but is connected to the sub-plate.
After removing the battery, remove the speaker module, the vibrator, and the USB interface soft board, and the USB interface is set with waterproof rubber circles.
Finally, the back cover left and right, the same axis and the back LEDs such as the back surface are removed. LED lights on the back of the back cover are connected to the panel, and the black shark game mobile phone 2's LED light is available.
Tower full-scale liquid cooling system detailed:
The heat dissipation design is undoubtedly the most eye-catching. The black shark game mobile phone 2 is named the heat dissipation plan as a tower-style liquid cooling system. This system has changed only by a heat conductive copper tube as a "liquid cold" material. Designed, most of the heat dissipation schemes are designed on the heat dissipation plate.
This heat sink is derived from the main, sub-plate and the battery side, and the most common "liquid cold" thermal copper tube in the game mobile phone is also upgraded to the black shark game mobile phone 2. Board + liquid cold copper tube design, liquid-cooled plate covers the main heat generation zone of the motherboard, and the liquid-cooled copper tube is located at the sub-plate, and strives to make the entire "liquid cool" system coverage greater.
There is no shield protection in the motherboard CPU position, so this heat dissipation plate is also protected. Such a design brings another advantage that the heat conductive silicone fat and the liquid cooling plate on the heat dissipation plate can directly contact the primary heat generating region. Further, the heat sink is close to the screen side as a large copper plate. When the heat is transferred to the liquid cold plate, the heat is cold copper tube, the heat can be diffused by the copper plate, and the graphite sticker of the corresponding battery position on the heat dissipation plate can absorb the heat dissipation plate. The heat at the intermediate void.
Therefore, in general, the heat dissipation efficiency with heat dissipation plates is high than the first two generations of black shark games.

Summary:
There is no doubt that the heat sink is used as an important heat dissipation program inside the mobile phone is the biggest highlight of the black shark game mobile phone 2. It is because the joining of this heat dissipation plate makes the internal design of the black shark game mobile phone 2 more complicated than a lot of Android phones.
However, this cooling design will only be seen in the game mobile phone in the game, after all, the comprehensive cost, actual use experience gap, even if the flagship model is not necessarily required to use such a powerful heat dissipation scheme.
