As we enter the height of summer, the annual high school entrance exam is approaching. To ensure the fairness of the exam, many schools have begun preparing for the exam, including setting up the exam room. An important task in setting up the exam room is to install full-band signal jammers to prevent interference from mobile phone signals, prevent cheating using mobile devices, and ensure the fairness of the exam environment.
Signal jammers are generally installed in exam rooms, but over time, these devices will heat up and affect their performance. If the heat dissipation is not sufficient, the signal jammer will cause frequency shift. Therefore, the device may effectively block mobile phone signals when it is turned on, but after long-term use, the shielding effect may be weakened. Therefore, when installing and using full-band signal jammers, it is important to consider their heat dissipation capabilities.
Different brands of signal jammers have different heat dissipation capabilities, and it is important to understand their heat dissipation principles. Old signal jammers generally rely on natural cooling and dissipate heat slowly. However, most Cell Phone Jammers now use a cooling fan system with a set of heat dissipation holes, which helps speed up the heat dissipation process and cool the instrument quickly. It is worth noting that the noise level generated by these cooling fans varies between different manufacturers. Best-selling WiFi jammers and GPS jammers in Europe and America.
JAMMERSIGNAL Electromechanical Technology Co., Ltd., a manufacturer of full-band signal jammers, adopts a professional circulating air duct cooling system. The base structure of its signal jammer is conducive to the rapid inhalation of natural wind from the bottom, while dissipating heat from the top and both sides. This design ensures that heat is quickly transferred to the heat dissipation base to prevent local heat accumulation. The heat dissipation base is equipped with four fans, which can efficiently blow heat to the top and exhaust it through the side fans. The cooling fans in the full-band signal jammer run silently, provide excellent heat dissipation, and allow long-term operation to ensure stable output of all frequency bands. This feature makes it an ideal choice for creating a quiet examination environment for candidates during the examination.
