How does a mobile phone jammer eliminate working heat?

No matter what kind of cell phone jammer (those small signal jammers) you use, they will heat up over time. Like any other electronic equipment, the internal components of the signal jammer will eventually generate heat. Therefore, it is recommended not to use the signal jammer without a reliable cooling system for a long time to prevent the cooler from being disturbed. In any case, more powerful mobile jammer devices will absorb more heat, and they need to have a cooling system to function properly. Portable jammers use fast cooling fans and air slots to achieve good ventilation and hot air exhaust. Desktop models use very few powerful cooling fans and reliable radiators to maximize heat dissipation.
