Basically, mobile phone signal jammers are installed in every examination room to prevent candidates from using mobile phones to cheat during the exam. Careful friends will find that the case of the jammer will be very hot after it is used for a period of time. We all know that electronic products will produce some heat more or less when they are used. If we do not heat the machine, it will affect the normal use of the machine. In serious cases, irreparable damage will be caused to the equipment.

This is enough to see that heat dissipation is very important for mobile phone signal jammer. In order to better achieve the interference effect, the manufacturer has also made every effort to dissipate the heat of the jammer. At present, the heat dissipation of the jammer by major manufacturers is basically two points, natural heat dissipation or the installation of a cooling fan. The way of natural heat dissipation is mostly seen in outdoor machines. The heat is dissipated into the atmosphere through the large area fins of the equipment shell. If there is wind, the heat dissipation effect of the jammer will be better. Of course, this is also a big test for the performance indicators of various components inside the machine, so all major manufacturers will choose the components with good performance and small impact of temperature rise, but the cost is also relatively high, So it is generally used on high-power machines. The other is to use the cooling fan for auxiliary heat dissipation. The machine generates heat. The cooling fan is used for auxiliary heat dissipation of the radiator to dissipate the heat as soon as possible. So as to minimize the impact of temperature rise on the equipment. Machines assisted by cooling fans are often seen in low-power mobile phone signal jammers. Of course, for special models, we will also choose to use the cooling fan to assist the heat dissipation of the jammer, such as the trolley box type, the backpack type jammer, and so on.
