However, the mobile phone signal shielding device does not have a good heat dissipation function in actual application. When the mobile phone signal shielding device is used uninterruptedly for a long time, if the heat generated continues to accumulate, it will cause damage to the mobile phone signal shielding device itself and the control panel therein, and there will also be safety hazards. Therefore, a high-quality mobile phone signal shielding device should have good heat dissipation and quickly dissipate the heat generated by the device to prevent the continuous high temperature from affecting the normal operation of the device.

[0004] In view of this, this application is hereby filed. Utility Model Content
