High power signal jammer overheating problem
A mobile phone jammer is a high-power, high-current device. It generates heat when it works. If it is not dissipated in time, it will affect the normal operation of the machine at least, and endanger personal safety at worst. Most electronic products or other power devices of the same type take the thermal conductivity of the machine very seriously.
Among the commonly used metal materials, silver has the best thermal conductivity, followed by copper and aluminum. However, silver is expensive and is rarely used for heat dissipation; although copper has good thermal conductivity, it does not dissipate heat quickly, which may cause the mobile phone signal jammer to work 24 hours a day, and the heat of the machine cannot be dissipated, forming an invisible space in a small space. If you encounter high temperatures in summer, the danger can be imagined.
In addition, schools today typically have air conditioning systems installed. If the weather is too hot, the school will turn on the air conditioner or fan to ensure the safety of candidates. At this time, the temperature of the warning screen in the examination room also decreased. In fact, this thing is like a mobile phone, and it is very hot when it is opened in summer.
However, the machine will heat up after a period of use, and the heat may affect the normal use of the machine. Once the heat is too late to dissipate, it will cause the frequency offset of the jammer.
Therefore, when the machine is first used, it can normally interfere with the mobile phone signal. After working for a while, some cell phones can't interfere. Therefore, the heat dissipation capacity of the jammer gps should be considered during installation and use. There are also differences in the heat dissipation capacity of the same brand of signal isolators.
It's just that the heat dissipation capacity varies from brand to brand. So how does the heat of the signal shield in the test room dissipate?
However, due to the different components used by different manufacturers, the noise levels generated by these fans during operation are also different.Now most of the signal isolators will open the cooling hole group and install the cooling fan, which can help the instrument to cool down as soon as possible.
