Of course, in terms of energy saving and heat dissipation, Borch's space-time built-in cell phone jammer cannot be compared with Borch's space-time external cell phone signal blocker. From the perspective of external structure, the built-in mobile phone signal shielding device integrates the transmitting antenna, power supply and heat dissipation fins in an external plastic shell, which is more beautiful in appearance, plug-and-play, and requires complicated antenna connections, plug-in power supplies, etc. advantage. And it has great advantages in areas where the flow of personnel is large, easy to manage, or frequently moved in some school examination rooms, conference rooms and confidential places.

Then the external mobile phone signal shielding device adopts thickened pure aluminum alloy in structure, and combines the circuit board and the shell through processes such as oxidation baking varnish, making full use of the shell to achieve good heat dissipation effect. Since the antenna is connected to the shape memory alloy head and the power supply is also connected, it is not conducive to long-term mobile use, complicated operation and inconvenient installation. However, due to the built-in mobile phone signal shielding device, the external heat dissipation effect is particularly strong. The better the matching and using effect of external transmitting antenna and shielding device. Since the power supply of the external mobile phone signal shielding device is separated from the host, it will not add additional burden to the host and can work stably for a long time. Combining the above advantages, the present invention is more suitable for school classrooms, student dormitories, churches, troops, prisons, detention centers and other fixed places that need to work continuously and stably for 365 days.
