Is heat dissipation important for mobile phone signal jammers? from dojammer's blog

Nowadays, mobile phone signal jammers are installed in almost every examination room to prevent candidates from cheating with their mobile phones during the examination. Those who are more careful will find that the jammer will be very hot after being turned on and used for a period of time. Everyone knows that electronic products will generate some heat more or less when in use. If the machine is not cooled, it will affect the normal use of the machine. In severe cases, it will cause irreparable damage to the equipment.

This is enough to show that heat dissipation is very important for mobile phone signal jammers. In order to better achieve the interference effect, manufacturers have also tried their best to dissipate the heat of the jammer. At present, major manufacturers have basically two points for the heat dissipation of jammers, natural heat dissipation or adding a cooling fan. The natural heat dissipation method is more common in outdoor machines. The heat is dissipated into the atmosphere through the large area of ​​the heat dissipation fins on the outer shell of the equipment. 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. Therefore, major manufacturers will choose devices with good performance and small temperature rise, but the cost is relatively high, so they are generally used in high-power machines. Another method is to use a cooling fan to assist in heat dissipation. The machine generates heat, and the cooling fan assists in cooling the radiator to dissipate the heat as quickly as possible. This minimizes the impact of the temperature increase on the device. Machines that use cooling fans to assist in heat dissipation are mostly small-power mobile phone signal jammers. Of course, for special models, cooling fans will also be used to assist in heat dissipation of the jammer, such as trolley-type and backpack jammers.
